Standards of Performance for New Stationary Sources: Volatile 
Organic Compound Emissions From the Synthetic Organic Chemical 
Manufacturing Industry Wastewater; Supplement to Proposed Rule

AGENCY: Environmental Protection Agency (EPA).

ACTION: Supplemental to proposed rule and notice of public hearing.

-----------------------------------------------------------------------

SUMMARY: On September 12, 1994, the EPA proposed Standards of 
Performance for New Stationary Sources: Volatile Organic Compound 
Emissions from the Synthetic Organic Chemical Manufacturing Industry 
Wastewater. On October 11, 1995, the EPA issued a supplement to the 
proposal. The action proposed today clarifies and revises the 
previously proposed rule and proposes to add Appendix J to part 60.
    Volatile organic compounds (VOC), when emitted into the ambient 
air, are precursors to the formation of tropospheric ozone. A wide 
variety of acute and chronic respiratory health effects and welfare 
(e.g., agricultural, ecosystem) effects have been attributed to 
concentrations of ozone commonly measured in the ambient air throughout 
the U.S.
    Appendix J to part 60, How to Determine Henry's Law Constants, Fm 
Values, Fr Values, and Fe Values for Organic Compounds, is being 
proposed today. This appendix provides the methodology for determining 
Henry's law constants, fraction measured (Fm) values, fraction removed 
values (Fr), and fraction emitted (Fe) values.

B. Health and Welfare Effects of VOC

    VOC, when emitted into the ambient air, are precursors to the 
formation of ozone at ground-level, where it can be harmful to breathe. 
It is the prime component of smog in cities. Exposure to ozone is 
associated with health effects and damage to vegetation. Ozone impairs 
normal functioning of the lungs and reduces the ability to perform 
physical exercise; the effects are more severe in individuals with 
sensitive respiratory systems. Symptoms associated with ozone exposure 
include cough, chest pain, and throat irritation. Emerging health 
effects information suggests some healthy adults engaged in moderate 
exercise for 6 to 8 hours may experience symptoms and reduction in lung 
function even at exposure levels below the current ozone health 
standard. Of perhaps greater concern are the potential chronic health 
effects that may result from repeated exposure to ozone over many 
seasons or a lifetime, such as inflammation of lung tissue, which 
precedes permanent scarring of lung tissue. Animal studies have shown 
that chronic ozone exposures of months to years do indeed cause 
permanent

[[Page 67989]]

reductions in lung function and lung tissue damage.
    Children are at a higher risk from ozone exposure than adults. They 
breathe more air per pound of body weight than adults and they spend 
more time outdoors, especially in the summer, when exposure to ozone is 
more prevalent. Because children's respiratory systems are still 
developing, they are more susceptible than adults to environmental 
threats.
    Studies of the major cash crops in the U.S. indicate that ozone is 
responsible for several billion dollars in agricultural crop yield loss 
each year. Ozone also causes noticeable foliar damage in many crops 
which reduces marketability and value. Finally, it appears that ozone 
is responsible for forest and ecosystem damage, which may be exhibited 
as foliar damage, reduced growth rate, and increased susceptibility to 
insects and disease.
    Some VOC that would be regulated by this rule, including benzene, 
hexane, methyl ethyl ketone, toluene, and naphthalene, are also organic 
hazardous air pollutants. These organic hazardous air pollutants are 
known to cause a range of adverse health effects such as: increased 
risk of cancer, aplastic anemia, pancytopenia, chromosomal breakages, 
weakening of bone marrow, polyneuropathy (muscle weakness and 
numbness), and cataracts and anemia in infants.

C. Background on the Rule

    On September 12, 1994 (59 FR 46780), the EPA proposed the NSPS for 
SOCMI wastewater in the Federal Register. On October 11, 1995 (60 FR 
52889), the EPA published a supplement to the proposed NSPS for SOCMI 
wastewater in the Federal Register. Both of these notices are also 
available on EPA's Technology Transfer Network (TTN) via the Internet.

II. Overview of Changes to the Proposed Rule

    Today the Agency is proposing revisions that are designed to 
clarify provisions of the proposed 40 CFR, part 60, subpart YYY. These 
proposed revisions address some of the public comments received in 
response to the September 1994 and October 1995 notices and incorporate 
some of the provisions promulgated in the HON, published on January 17, 
1997 (62 FR 2721). If promulgated, the proposed revisions retain the 
same basic control requirements and best demonstrated technology as the 
proposed rule. Best demonstrated technology for this rule was discussed 
in the September 12, 1994 preamble, 59 FR 46733. A summary of the 
revisions is provided in the following paragraphs.
    The applicability and date of compliance section (Sec. 60.770) has 
been revised to improve clarity and incorporate certain concepts 
relevant to applicability of the rule. Concepts such as designated 
chemical process unit and primary product have been added. The 
requirement that an affected facility must generate a wastewater stream 
has been removed. Modified facilities will have to be in compliance by 
initial startup or promulgation, whichever is later. In addition, 
provisions have been added to Sec. 60.772 to clarify how to determine 
whether an affected facility has been modified.
    Seven sections have been substantially revised in today's 
amendments to improve clarity and to incorporate the new ``point of 
determination'' concept discussed in section VI. of this preamble. The 
seven sections address the following topics: criteria for determining 
the Group 1 and Group 2 wastewater streams (Sec. 60.773); compliance 
options for wastewater tanks, surface impoundments, containers, 
individual drain systems, and oil-water separators (Sec. 60.774); 
performance standards for process wastewater (Sec. 60.779); procedures 
for determining Group 1 and Group 2 wastewater streams (Sec. 60.782); 
procedures for demonstrating compliance (Sec. 60.783); alternative 
monitoring and recordkeeping systems, one excursion per control device 
per day, excused excursions, clarification of monitoring parameter 
value violations, and Notification of Compliance Status (Sec. 60.784); 
and recordkeeping provisions (Sec. 60.785). Also, sections addressing 
aqueous in-process streams (Sec. 60.775); maintenance wastewater 
(Sec. 60.776); and, start-up, shutdown, and other provisions 
(Sec. 60.787) have been added.
    Changes are also proposed to the sections governing control 
devices, delay of repair, monitoring, recordkeeping, and reporting, and 
the proposed rule's relationship to other rules. The list of SOCMI 
chemicals that trigger the rule's applicability was previously in 
Sec. 60.788; it is now in Table 1 to subpart YYY. Other tables have 
been added to the subpart, and all the tables have been renumbered.
    As a result, today's provisions are being proposed in Secs. 60.770 
through 60.789, in Tables 1 through 14, and in appendix J to part 60. 
This preamble is organized in the order of the proposed rule sections.

III. Revisions to Requirements for Determining Applicability and 
Date of Compliance (Sec. 60.770)

A. Applicability and Affected Facility Determination

1. Overview of Applicability and Affected Facility Determination
    The application of the NSPS to SOCMI wastewater facilities under 
both the September 1994 proposal and today's revisions is predicated on 
a chemical process unit (CPU) that produces a chemical on the list of 
SOCMI chemicals in Table 1, and that commences construction or 
reconstruction, or is modified after September 12, 1994. However, 
today's revisions add the designated CPU concept, remove the 
requirement that an affected facility must generate a wastewater, add 
the primary product concept, provide a list of processes which are not 
considered SOCMI processes, clarify how storage vessels are assigned to 
a CPU, and include other clarifying edits.
2. Chemical Process Unit and Designated Chemical Process Unit
    The term ``chemical process unit'' is used instead of ``process 
unit,'' which was used in the September 1994 proposal. These two terms 
and the term ``chemical manufacturing process unit'' used in the HON 
have essentially the same meaning. The difference is that the 
definition of chemical process unit does not include transfer racks. 
Transfer racks were removed from the definition because the amount of 
wastewater they generate is insignificant and more difficult to control 
as compared to individual drain systems and storage vessels.
    The chemical process unit (CPU) is the basis for determining 
whether the process equipment is SOCMI as it was for the original 
proposal. As explained in section IV.D. of the September 12, 1994 
preamble, using the CPU as the basis for the applicability 
determination has several advantages including maintaining consistency 
with the HON and reflecting industry construction practices.
    While the CPU is the basis for determining SOCMI, today's revisions 
propose using the ``designated CPU'' as the basis for determining 
whether construction, reconstruction, or modification has occurred. The 
designated CPU is either the entire CPU, a process line within the CPU, 
or a combination of process lines within the CPU. The owner or operator 
may assign

[[Page 67990]]

either a process line, or combination of process lines, within the CPU 
as a designated CPU. However, once the assignment of process lines and 
associated storage vessels has been made, it is irrevocable.
    EPA believes incorporating the designated CPU concept would add 
flexibility for industry while supporting EPA's long-term goals of 
protecting human health and the environment. Industry commented that 
the cost of compliance with the rule would, in some cases, be many 
times greater than the cost of the change. This could result in 
unintended consequences, such as reluctance to make process 
improvements, that would be damaging to industry's ability to compete 
in the world market. In addition, EPA believes that changes in SOCMI 
are on-going and that most designated CPU's would meet the 
applicability criteria of the rule over time.
    The proposed rule excludes certain processes from the definition of 
CPU because they are not SOCMI processes, but are sometimes associated 
with SOCMI. Other SOCMI rules have also excluded these processes. The 
processes excluded are as follows: (1) research and development 
facilities; (2) petroleum refining processes (but not CPU located at 
petroleum refinery plant sites); (3) chemical process units located in 
coke by-product recovery plants; (4) solvent reclamation, recovery, or 
recycling operations at hazardous waste treatment, storage, and 
disposal facilities (TSDF) requiring a permit under 40 CFR 270 that are 
not part of a CPU; and, (5) organic chemicals extracted from natural 
sources or totally produced from biological synthesis such as pinene 
and beverage alcohol. Determinations for excluding processes must be 
based on the designation for the process unit, in contrast to the plant 
site.
3. CPU Must Manufacture a SOCMI Product as its Primary Product
    Today's action incorporates the concept of ``primary product'' into 
the rule's applicability determination. The primary product 
determination is made for a CPU. If the product(s) of the CPU, on a 
mass basis, are comprised of 50 percent or more of the SOCMI chemicals 
listed in Table 1 of the rule, the CPU's primary product is SOCMI. For 
purposes of this rule, ``product'' includes products, co-products, and 
by-products manufactured by the CPU. ``Product'' does not include 
isolated intermediates, impurities, wastes, and trace contaminants.
    The primary product determination is dependent upon the quantity of 
each chemical produced by the CPU and whether expected use of the CPU 
is known. The primary product provisions address both cases: (1) the 
expected use of the CPU is known for a 12-month period and (2) the 
expected use of the CPU is unknown for a 12-month period. When owners 
or operators know the expected use of the CPU, the primary product 
determination is based on the mass of product produced. If a CPU 
produces 50 percent or more, by mass, of the chemicals listed in Table 
1, the primary product is SOCMI.
    For some contract manufacturing units, the owner or operator may 
not be able to predict production sufficiently to make a primary 
product determination. In these cases, the primary product of the CPU 
is SOCMI once the facility begins producing a SOCMI chemical or has a 
contract to produce a SOCMI chemical.
    EPA adopted the primary product approach to simplify applicability 
determinations, to limit the applicability of the rule to those CPU 
that produce mostly the chemicals listed in Table 1 of the rule, and to 
make the proposed rule more like the HON.
    The revised proposed rule simplifies the determination of SOCMI in 
two ways. First, together with the definition of ``product,'' it 
clarifies the meaning of the terms ``product'' and ``to produce'' and 
the correct way to decide whether a source ``produces'' a listed 
chemical. Second, the primary product concept provides clear criteria 
for making a determination.
    The primary product concept also limits the applicability of the 
rule to CPU that produce mostly SOCMI products. In the September 1994 
proposal, by-products, co-products, and intermediates produced by the 
CPU and listed in Table 1 of the rule, in any amount, made the CPU a 
SOCMI unit. This could have resulted in numerous non-SOCMI process 
units, such as pharmaceutical units, being designated SOCMI and being 
subject to the SOCMI Wastewater NSPS. The proposal addresses this by 
establishing the 50 percent threshold. Although this change will reduce 
the number of CPU affected by the rule, it more accurately reflects the 
SOCMI source category.
    EPA believes that making the SOCMI Wastewater NSPS as much like the 
HON as possible will facilitate implementation of the rule. The HON and 
the SOCMI Wastewater NSPS will regulate the same types of process units 
and treatment processes, and in some cases, the same process units and 
treatment processes. Thus, the primary product concept was adopted for 
the proposal.
    Today's revisions use expected annual production as the basis for 
determining the mass for each product. Expected annual production is 
proposed instead of annual design capacity to accommodate CPU designed 
and operated to manufacture more than one chemical. Typically these 
facilities are contract manufacturing facilities, also known as tolling 
or multi-purpose facilities or flexible operations facilities. Using 
expected annual production allows a facility to more closely represent 
actual production rather than basing the primary product decisions for 
each chemical on annual design capacity. The facility would also have 
to report the CPU's annual design capacity. However, EPA is concerned 
whether this approach creates potential burden for regulating agencies 
and requests comment on whether expected production or design capacity 
should be used.
4. Designated CPU Must Have Been Constructed, Reconstructed or Modified 
After September 12, 1994
    To be subject to this proposed rule, a designated CPU must have 
been constructed, reconstructed, or modified after September 12, 1994.
5. Affected Facility Must Generate a Process Wastewater, a Maintenance 
Wastewater, and/or an Aqueous In-Process Stream for Control 
Requirements To Apply
    In the original proposal, an affected facility had to be a process 
unit that generated wastewater. ``Wastewater'' included process 
wastewater and maintenance wastewater. Today's revised proposal removes 
``generating wastewater'' as a criteria for determining applicability.
    This change to the applicability determination was done for two 
reasons. First, to remove maintenance wastewater from triggering 
applicability of the rule to a designated CPU. Maintenance wastewater 
is generally more difficult to quantify and EPA believes is a less 
significant source of VOC emissions than process wastewater for this 
source category. Second, in the September 1994 proposal, ``wastewater'' 
was defined as ``an organic containing water . . .,'' without regard to 
the concentration of VOC in the wastewater. Today's revised proposal, 
adds a concentration of 50 part per million, by weight, (ppmw) into the 
wastewater definition. Thus, low concentration wastewater streams that 
would have triggered applicability in the original proposal would not 
do so with the revised wastewater definition. EPA intends that a 
designated CPU that is

[[Page 67991]]

new or reconstructed or modified after September 12, 1994 and that is 
part of a CPU that produces SOCMI as its primary product control 
process wastewater streams, maintenance wastewater streams, and aqueous 
in-process streams when the streams are generated.
    EPA recognizes that affected facilities that do not generate 
wastewater or aqueous in-process streams should not be subject to all 
the reporting and recordkeeping requirements. Therefore, EPA has 
specified that affected facilities that do not generate process 
wastewater streams, maintenance wastewater streams, or aqueous in-
process streams are exempt from most of the provisions of the subpart. 
If the affected facility began generating a process wastewater stream, 
a maintenance wastewater stream, or aqueous in-process stream, it would 
have to comply with all applicable provisions of the subpart at the 
time of the change.
6. Applicability of Part 60 and Part 63 General Provisions
    Today's proposal adds table 2 and table 2A, which clarify the 40 
CFR part 60 and part 63 general provisions that apply to this rule. 
There was a need for selected part 63 general provisions to apply to 
this part 60 rule because the part 60 general provisions do not contain 
certain provisions that were used by the HON and are necessary for 
compliance with this rule. The applicable part 63 general provisions 
pertain to the start-up, shutdown, and malfunction plan, performance 
testing requirements, control device requirements, and delegated 
authority.

B. Date of Compliance

    In October 1995 the Agency proposed to allow modified sources 
undergoing significant capital improvements an additional three years 
to come into compliance with the SOCMI Wastewater NSPS. The additional 
time would have been subject to the Administrator's approval and would 
have required documentation of the need for more time.
    Today's revised proposal would require that all affected facilities 
be in compliance with the NSPS no later than initial start-up of an 
affected facility or promulgation of the rule, whichever is later.
    In response to the September 1994 proposal, several commenters 
wrote that the applicability and compliance provisions were unclear 
making it difficult for them to implement any requirements. In 
addition, EPA recognizes that some facilities may require several 
months or years lead time to complete large capital projects such as 
retrofitting sewers and designing and installing steam strippers. 
Facilities need time to determine whether the rule applies to them, 
familiarize themselves with the rule, choose a compliance option, 
design the necessary equipment, and construct and renovate as needed.
    To provide time for facilities that commenced construction, 
reconstruction, or modification between September 12, 1994 and the 
promulgation date, EPA is proposing to promulgate this rule no earlier 
than spring 2000. Appendix J to part 60 may be promulgated earlier.
    Facilities commencing construction, reconstruction, or modification 
after the promulgation date will be required to be in compliance upon 
initial start-up. As is the case under all other NSPS, facilities will 
have to plan ahead to complete any necessary construction at a facility 
so as to be in compliance with the NSPS upon start-up of operations.
    Today's revised proposed rule would limit modifications to changes 
costing 12.5 percent or more of the cost of the existing facility. This 
is discussed in section V. of this preamble. Because the cost test 
precludes relatively smaller changes from triggering the NSPS, only 
larger projects will be modifications. The larger projects take more 
time to plan and implement, giving the facility time to plan for 
compliance. Therefore, the facilities that become modified after the 
promulgation date will have adequate notice of the requirements and 
sufficient time to plan for compliance.

IV. Revisions to the Definitions (Sec. 60.771)

A. Overview of Changes to the Definitions

1. Definitions Added
    Significant changes were made to the definition section of the 
rule. The following definitions were added to Sec. 60.771: aqueous in-
process stream; automated monitoring and recording system; chemical 
process unit; closed biological treatment process; designated chemical 
process unit or designated CPU; enhanced biological treatment system or 
enhanced biological treatment process; flexible operation unit; Fbio; 
Fe; Fr;, Fr; fuel gas; fuel gas system; incinerator; initial start-up; 
modification; non-automated monitoring and recording system; on-site or 
onsite; open biological treatment process; petroleum refining process 
or petroleum refining process unit; plant site; point of determination; 
product; recapture device; recovery device; research and development 
facility; shutdown; specific gravity monitoring device; start-up; 
start-up, shutdown, and malfunction plan; steam jet ejector; storage 
vessel; tank drawdown; unit operation; volatile organic compound or 
VOC; and wastewater tank.
2. Definitions Removed
    The following definitions were removed from Sec. 60.771: mass flow 
rate, operating parameter value, point of generation, process unit, 
process unit shutdown, tank, and volatile organic concentration.
3. Definitions Changed
    The following definitions were changed: annual average 
concentration, annual average flow rate, boiler, closed-vent system, 
container, continuous record, continuous recorder, continuous seal, 
control device, cover, duct work, flame zone, flow indicator, hard-
piping, individual drain system, oil-water separator or organic water 
separator, process wastewater, residual, sewer line, temperature 
monitoring device, treatment process, waste management unit, 
wastewater, and wastewater seal controls. Most of these revisions were 
to make the definitions in today's proposed rule consistent with those 
in the HON.

B. Significant Definitional Changes

    Significant definitional changes proposed are as follows: revisions 
to the ``wastewater'' definition; revisions to the ``product'' 
definition; replacement of the ``point of generation'' (POG) definition 
with ``point of determination'' (POD) definition; addition of 
``closed'' and ``open biological treatment process'' definitions; 
addition of the ``enhanced biological treatment system'' definition; 
revisions to the ``individual drain system'' definition; and, revisions 
to the ``VOC'' definition.
    The definitions of ``wastewater,'' ``recovery device,'' and ``point 
of generation'' were revised to clarify EPA's intent concerning which 
VOC-containing waters are in-process fluids regulated by the provisions 
in Sec. 60.775 and which are wastewater and regulated by the provisions 
in Sec. 60.773 and Sec. 60.779 through Sec. 60.783.
1. Revised Wastewater Definition
    The most significant change proposed today to the ``wastewater'' 
definition is the addition of the concept of ``discard.'' This concept 
is fundamental to distinguishing which fluids exiting the CPU are 
subject to the SOCMI Wastewater NSPS provisions in Sec. 60.773. Adding 
``discard'' to the definitions provides a clear demarcation

[[Page 67992]]

between those fluids no longer useful to that production process, i.e., 
discarded, and those fluids that add value to that production process. 
Together with the point of determination and aqueous in-process stream 
concepts, the revised definition of wastewater makes it easier for 
facilities and regulatory authorities to implement the rule.
    2. Replaced Point of Generation With Point of Determination
    Today's revised proposal changes the definition of ``point of 
generation'' to ``point of determination.'' The change is to reflect a 
conceptual difference. ``Point of generation'' was defined in the 
September 1994 proposed rule as ``the location where process wastewater 
exits the process unit equipment.'' In today's revised proposal, it has 
been replaced by ``point of determination'', which is defined as ``each 
point where the process wastewater exits the chemical process unit,'' 
often the last recovery device. The need for and significance of this 
change is discussed in more detail in section VI.B. of this preamble.
3. Recovery Device
    Today's revised proposed rule includes a revised definition of 
``recovery device.'' The proposed definition of ``recovery device'' 
differs from the existing definition in order to reflect the revised 
approach to the definition of ``wastewater'' and to reflect the fact 
that deviations from normal operations do occur. This was discussed in 
the HON preamble of August 26, 1996 (61 FR 43710).
    The revised definition of ``recovery device'' is intended to 
eliminate the potential for sham transactions involving the ``sale'' of 
wastewater by limiting the concept of sales to sales for the same 
general purposes for which chemicals may be recovered and used within 
the facility (i.e., use, reuse, or burning as fuel). The EPA believes 
that the revised definition is broad enough to encompass any sale that 
is not a sham since ``use'' and ``reuse'' are very general concepts. 
The definition also differs from the existing definition in that the 
word ``normally'' now modifies the phrase ``used for the purpose of 
recovering. . . .'' This change was made to recognize that occasional 
exceptions to normal usage can and will arise.
4. Added Definitions for Closed Biological Treatment Process, Open 
Biological Treatment Process, and Enhanced Biological Unit
    Definitions for closed biological treatment process, open 
biological treatment process, and enhanced biological treatment system 
were added to the definitions in Sec. 60.771. The new definitions are 
necessary to make distinctions among biological treatment processes 
which allow the incorporation of more flexible and less burdensome 
compliance demonstrations for some facilities. This is discussed in 
more detail in the discussion of changes to Sec. 60.783 in section XI. 
of this preamble.
5. Modified Individual Drain System Definition
    The definition for individual drain system would be modified to 
clarify three key concepts and incorporate minor wording changes. The 
definition in today's proposal would clarify that only stationary 
systems are included in the definition; that individual drain systems 
are used to convey residuals as well as wastewater streams; and that 
the individual drain system does not include in-process equipment as 
described in Sec. 60.775.
6. Modified VOC Definition
    VOC, for the purposes of this subpart, are defined to be those 
substances already defined as volatile organic compounds in 40 CFR 
section 51.100(s) and that are not excluded or exempted by that 
section, except that any substance with a Henry's law constant less 
than or equal to 0.1 y/x atmosphere per mole fraction as determined 
according to Appendix J of this subpart is not a VOC for the purposes 
of this subpart.
    This definition of VOC reflects EPA's belief that chemicals with 
lower Henry's law constants are not a significant source of VOC 
emissions from wastewater. A Henry's law constant of 0.1 y/x at 
25 deg.C is similar to the lowest Fe value for the HAP controlled by 
the HON. In selecting which compounds to control, EPA also considered a 
compound's biodegradability and Fr value. In general, lower volatility 
compounds are already significantly biodegraded and are not removed to 
a significant extent by steam stripping.

V. Revisions to Requirements for Determining Modification 
(Sec. 60.772)

1. Modification

    Today's proposed rule revises Sec. 60.772 to clarify how to 
determine whether a designated CPU has been modified such that it is 
subject to the SOCMI Wastewater rule. The revisions add a definition of 
``modification'' in Sec. 60.771; clarify that the designated CPU is 
used as the basis of modification determinations; provide exclusions to 
modification; and, provide procedures to determine increases from 
process wastewater and aqueous in-process streams.
    Modification, as defined in Sec. 60.771, means ``any physical 
change in, or change in the method of operation of, an existing 
designated CPU which increases or creates emissions to the atmosphere 
of VOC from process wastewater and/or aqueous in-process streams 
generated by the designated CPU, except as provided in 
Sec. 60.772(c).'' This definition supersedes for the purposes of 
subpart YYY the definition in Sec. 60.2 of the General Provisions to 40 
CFR, part 60. The proposed definition incorporates the concept that 
only process wastewater and aqueous in-process streams are considered 
for modification determinations; maintenance wastewater is not 
considered. It also states that the basis of the modification is the 
designated CPU, making the modification provisions consistent with the 
applicability provisions for subpart YYY.
    Today's revisions also replace the exclusions to what constitutes a 
modification in Sec. 60.14(e) of the general provisions with four 
exclusions. Three of these are similar to exclusions provided by 
Sec. 60.14(e)--maintenance, repair, and replacement, including 
replacement of spent catalyst with the same catalyst; increase in hours 
of operation; and, relocation or change in ownership of an existing 
facility.
    The fourth exclusion is for changes that cost less than 12.5 
percent of the cost of the existing designated CPU. This concept is 
also used in the SOCMI rule for equipment leaks, subpart VV to part 60. 
It is meant to encompass any change, including, an increase of 
production rate, environmental control, and bottleneck removal. One 
reason a percent cost exclusion was added is in recognition that SOCMI 
equipment routinely undergoes small changes and that EPA does not 
intend small changes to constitute a modification for this rule. 
Another reason is that this exclusion provides a clear and simple 
statement of what is not a modification. EPA chose 12.5 percent because 
12.5 percent was used in the SOCMI rule for equipment leaks, subpart VV 
to part 60. In addition, the General provisions to part 60 use the 12.5 
percent level in an exclusion for an increase in production rate (see 
Sec. 60.14(e)(2), Sec. 60.14(2), definition of ``capital expenditure, 
and Internal Revenue Service Publication 534). When two or more 
physical or operational changes are reasonably viewed as a project, the 
cost of the entire project should be considered when determining the 
12.5 percent.
    Today's proposed revisions add provisions for determining whether 
an increase in VOC emissions from process

[[Page 67993]]

wastewater or aqueous in-process streams has occurred or will occur. 
The proposed provisions make a distinction between flexible operations 
units and non-flexible operations units. The flexible operations units, 
which manufacture more than one product, choose one product as a 
baseline against which to compare emissions that occur due to changes. 
This approach was outlined in a memo entitled ``Clarification of 
Methodology for Calculating Potential to Emit (PTE) for Batch Chemical 
Production Operations' which was issued by John S. Seitz, the director 
of EPA's Office of Air Quality Planning and Standards, to the 10 EPA 
Regional Offices on August 29, 1996.
    For both flexible operation units and non-flexible operation units, 
the owner or operator would calculate VOC emissions before and after a 
physical or operational change. The owner or operator may elect to 
determine the amount of VOC emissions by calculating VOC mass flow rate 
in the wastewater as a surrogate for VOC emissions or by calculating 
VOC emissions using a fraction emitted, Fe, value. The Fe value may be 
either a default Fe value or a site-specific Fe value. The default Fe 
values are listed in Table 2 of the proposed appendix J to this part. 
The site-specific Fe values are determined according to the procedures 
and forms specified in the proposed appendix J to this part.
    Once the VOC mass flow rate or VOC emissions have been determined 
both before and after the change, they must be compared to determine 
whether the change caused an increase in VOC emissions to the 
atmosphere. When emissions are determined using mass flow rate as a 
surrogate for emissions, the VOC mass flow rate before the change for 
all process wastewater streams affected by the change are compared to 
the VOC mass flow rate after the change for all process wastewater 
streams affected by the change. The same comparison is done for aqueous 
in-process streams. If either comparison, i.e., the process wastewater 
comparison or the aqueous in-process streams comparison, demonstrates 
that VOC mass flow rate has increased after the change, the designated 
CPU is modified and becomes an affected facility. In contrast, when 
emissions are determined using Fe values, the sum of all affected 
process wastewater streams and all affected aqueous in-process streams 
before the change are compared to the sum of all affected aqueous in-
process streams and all affected process wastewater streams after the 
change.

2. Reconstruction

    Today's revisions clarify when costs begin accumulating for 
purposes of reconstruction, clarify the accumulation period, and add a 
requirement for documentation. The reconstruction of an affected 
facility subjects it to the NSPS because the replacement of the 
components of an existing facility eventually results in a new 
facility. The general provisions to 40 CFR, part 60 sets the level of 
replacement that constitutes reconstruction at 50 percent or greater of 
the cost of constructing a comparable new facility. EPA is proposing 
that the first day replacement costs for actual work, i.e., dismantling 
of equipment or construction, on the facility are incurred, the costs 
are ``charged'' to the designated CPU for the purpose of determining 
reconstruction. When replacement of components is reasonably viewed as 
a project, the cost of the entire project would be charged to the first 
day expenses were incurred. All replacement costs must be counted 
toward the reconstruction cost, regardless of whether costs arise from 
different projects.
    The September 12, 1994 proposal set a time period of two years as 
the period that project costs should be aggregated and counted toward 
reconstruction. Today's notice clarifies that the two year period is a 
rolling two year period. A rolling two year period is not based on a 
specific set of dates. A rolling two year period allows any day to be 
used as the beginning point for the two year period. Thus, the two year 
period can be considered to any 730 consecutive days. The rolling two 
year period should be examined to see if all combined replacements to 
the facility cost 50 percent or more of the cost of constructing a new 
facility that would be comparable in cost to the existing facility. The 
cost of all projects incurred within a two year period would be added 
together.

VI. Revisions to the General Requirements for Process Wastewater 
(Sec. 60.773)

    The EPA is proposing changes to the general process wastewater 
provisions in Sec. 60.773. These provisions provide instructions on how 
to determine if a process wastewater stream requires control and the 
general outline of requirements for process wastewater streams. These 
changes are consistent with the changes made to the wastewater 
provisions in the HON rule. Significant changes proposed include the 
following: requirements for determining whether wastewater streams 
require control by determining Group 1 or Group 2 status, replacement 
of point of generation with point of determination, addition of 
prohibition of discarding certain organic material into water or 
wastewater, and the addition of off-site treatment requirements. The 
off-site treatment provisions require that an owner or operator may 
only ship to a facility that has certified that it will treat the 
wastewater to the standard required by the rule.

A. Group 1/Group 2 Status Determination

    The EPA is proposing using Group 1 and Group 2 terminology to 
determine whether a process wastewater stream requires control for VOC. 
Determination of whether a process wastewater stream is Group 1 or 
Group 2 is based on annual average concentration and flow rate 
criteria. Control requirements for Group 1 wastewater streams require 
that VOC emissions be controlled until the VOC are either removed from 
the wastewater or destroyed. Group 2 wastewater streams are required to 
comply with certain recordkeeping and reporting requirements. The 
proposed control criteria of 500 ppmw at a flow rate of 1 liter per 
minute (lpm) or 10,000 ppmw at any flow rate have not changed.

B. Change From Point of Generation to Point of Determination

    Today's revised proposed rule predicates the determination of the 
applicability of control requirements to a wastewater stream on its 
characteristics at the point where the wastewater stream exits the last 
piece of processing equipment. The new location for determining the 
characteristics of a wastewater stream is being called the point of 
determination (POD) to distinguish it from the POG concept used in 
other air rules for waste and wastewater such as the Benzene Waste 
NESHAP. In instances where the wastewater stream exits the process 
equipment and is not sent to a recovery device that recovers chemicals 
for fuel value, use, reuse, or for sale (for fuel value, use, or reuse) 
the POD would be the same as the POG location. The POD concept proposed 
for this rule is the same as used in the HON.
    The EPA's intent in developing the POD approach is to have a clear 
decision criterion that specifies the location for evaluation of a 
wastewater stream for the purposes of control. The POD encompasses each 
point where process wastewater exits the last piece of process 
equipment, often the last recovery device. There can be multiple POD 
associated with a CPU or

[[Page 67994]]

designated CPU. This proposed definition of POD would allow a facility 
to recover chemicals for fuel value, use, reuse or for sale (for fuel 
value, use, or reuse). As with the POG, under the POD approach owners 
and operators would not be allowed to mix streams together for the 
purpose of escaping compliance by the diluting of wastewater streams. 
Under the POD approach, process units conveying process fluids in the 
chemical process unit are subject to the requirements established in 
Table 6 of the rule. Table 6 is consistent with the suppression 
requirements for a wastewater stream requiring control. Again, the 
intent is to allow process fluids that have recovery potential to be 
sent to recovery devices; however, these fluids are required to be 
managed to limit VOC emissions to the atmosphere. Process fluids that 
do not have recovery potential are considered wastewater streams at the 
point where the stream exits the process equipment. A more detailed 
discussion is available in section IV.D. of the HON preamble published 
on August 26, 1996 (61 FR 43698).

C. Prohibition of Discarding Certain Organic Materials into Water or 
Wastewater

    Language that prohibits discarding of certain organic material into 
water or wastewater has been added to Sec. 60.773. Specifically, liquid 
or solid organic materials containing greater than 10,000 parts per 
million of VOC may not be discarded into water or wastewater unless the 
receiving stream is managed and treated as a Group 1 wastewater stream. 
The prohibition would exclude equipment leaks; activities included in 
maintenance or start-up/shutdown/malfunction plans; spills; and 
samples. This paragraph was added to ensure that high concentration 
organic streams, such as off-specification product, are discarded only 
to individual drain systems and treatment processes meeting the 
requirements for Group 1 wastewater streams.

D. Addition of Off-Site or Third-Party Treatment Requirements

    Today's proposed rule would allow owners and operators to transfer 
Group 1 wastewater streams or residuals off-site for treatment provided 
the transferee certifies to EPA (and provides a copy to the owner or 
operator) that it will manage and treat the wastewater streams or 
residuals in accordance with this rule's provisions. These provisions 
were revised to provide a means to allow transfers of treatment 
responsibility without holding the owner or operator responsible for 
the actions of another and are consistent with the HON provisions.

VII. Revisions to Requirements for Wastewater Tanks, Surface 
Impoundments, Containers, Individual Drain Systems, and Oil-Water 
Separators (Sec. 60.774)

    Today's revised proposed rule adds additional compliance options 
for wastewater tanks, surface impoundment, containers, individual drain 
systems, and oil-water separators. The six compliance options that may 
be selected are as follows: HON, part 63, subparts F and G; Standard-
standards, part 63, subparts QQ, PP, RR, and VV; Petroleum Refinery, 
part 60, subpart QQQ; RCRA, part 264, subpart CC; RCRA, part 265, 
subpart CC; and Benzene Waste, part 61, subpart FF.
    Table 3 was added to today's revised proposed rule in order to 
indicate which of the six compliance options may be used as a control 
option for wastewater tanks, surface impoundment, containers, 
individual drain systems, and oil-water separators. Table 5 was added 
to today's revised proposed rule in order to identify the control 
requirements, monitoring provisions, recordkeeping provisions, 
reporting provisions, control device provisions, leak detection 
provisions, and delay of repair provisions for each of the six 
compliance options.
    As shown in Table 3, the owner or operator must comply with the 
control requirements for one of the six compliance options. If an owner 
or operator has a waste management unit that is subject to any of the 
six compliance options, then the owner or operator may choose to comply 
with the delay of repair provisions, monitoring provisions, 
recordkeeping provisions, reporting provisions, control device 
provisions, and leak detection provisions in the selected compliance 
option or in this subpart. If an owner or operator was not subject to 
the control requirements for any of the six compliance options, then 
the owner or operator must comply with the delay of repair provisions, 
monitoring provisions, recordkeeping provisions, reporting provisions, 
control device provisions, and leak detection provisions of this 
subpart.

VIII. Addition of Requirements for Control of Certain Aqueous In-
Process Streams (Sec. 60.775)

    The revisions adding a new Sec. 60.775 and Table 6 are an outgrowth 
of the change from the point of generation (POG) concept of the 
September 1994 rule to the point of determination (POD) concept in 
these revisions. As discussed in Section XI. of this preamble, the 
point of the determination concept is replacing the point of generation 
concept. The purpose of this new section is to ensure that VOC-
containing fluids are properly managed in closed systems. Table 6 lists 
the applicable requirements for a drain or drain hub, manhole, lift 
station, trench, oil-water separator, and a tank.
    In developing the point of determination approach, the EPA assumed 
that fluids containing organic compounds within the process would be 
managed in closed systems to minimize losses of a recoverable material. 
The provisions in Table 6 and the new Sec. 60.775 were designed to 
ensure that conveyance and handling of process fluids containing 
volatile organic compounds would be handled in a manner consistent with 
the requirements for wastewater streams subject to control.

IX. Addition of Requirements for Maintenance Wastewater 
(Sec. 60.776)

    The EPA is proposing changes to the maintenance wastewater 
requirements in the proposed rule. In the September 1994 proposal, 
maintenance wastewater and process wastewater were subject to the same 
provisions in Sec. 60.773 and Sec. 60.779. The maintenance wastewater 
provisions, which can now be found in Sec. 60.776 of the rule, were 
changed to be consistent with the HON maintenance wastewater 
provisions. The provisions require the owner or operator to provide a 
description of their procedures for managing wastewater generated from 
the emptying and purging of equipment in the process during temporary 
shutdowns for inspections, maintenance, and repair and during non-
shutdown periods such as routine maintenance. A description of these 
procedures will be included in a facility's start-up, shutdown, and 
malfunction plan.

X. Addition of Requirements for Determining Stream-Specific List of 
VOC (Sec. 60.778)

    Today's revised proposed rule provides a procedure that would allow 
a facility to develop a stream-specific list of VOC. The stream-
specific list of VOC could be used to estimate changes in emissions for 
modification determinations, to make Group 1 and Group 2 
determinations, and to make compliance demonstrations. EPA believes 
adding these provisions provides flexibility without sacrificing 
compliance assurance. EPA is proposing to add these requirements as 
Sec. 60.778.

[[Page 67995]]

A. Group 1 and Group 2 Determinations and Modification Determinations

    When a stream-specific list of VOC is needed to make a Group 1 
determination, the owner or operator must identify up to 75 chemicals 
(those with the greatest mass). The chemicals on the stream-specific 
list must represent at least 90 percent of the total VOC in the process 
wastewater stream. Chemicals with a concentration less than 1 ppmw can 
be excluded from the list. Method 25 D in appendix A to part 60 must be 
used when at least 90 percent of the total VOC in the wastewater stream 
cannot be identified. The same procedures are used when a stream-
specific list of VOC is needed to estimate changes for modification 
determinations.

B. Compliance Determinations

    When a stream-specific list is needed to make a compliance 
determination, three cases exist. The first case is when an owner or 
operator knows at least 90 percent of the total VOC in the wastewater 
stream. In this case, each chemical that has a mass of 5 percent or 
greater, must be included on the list. If less than half of the total 
VOC in the wastewater stream are represented by chemicals with a mass 
of 5 percent or greater, each chemical, up to 75 chemicals, must be on 
the stream-specific list. The second case is when an owner or operator 
knows at least 50 percent of the total VOC in the wastewater stream. In 
this case, the chemicals with the greatest mass that can be identified 
up to 75 chemicals are required to be included on the stream-specific 
list. For both of these cases, the owner or operator must: (1) ensure 
the stream-specific list of VOC is adequate to demonstrate compliance, 
and (2) document the method used to determine concentration and total 
VOC in the wastewater stream.
    The third case is for all other streams. An owner or operator who 
cannot identifiy at least 50 percent of the total VOC in the wastewater 
stream must choose a compliance option that does not require 
speciation. Three compliance options do not require speciation: (1) the 
design steam stripper option (Sec. 60.779(d)); the 95 percent and 
outlet reduction of 50 ppmw mass removal/destruction option for 
nonbiological treatment process (Sec. 60.779(e)(2)); and, the steam 
stripper three compound option (Sec. 60.779(e)(3)).

XI. Revisions to Requirements for--Performance Standards for 
Process Wastewater (Sec. 60.779)--Procedures for Determining Which 
Process Wastewater Streams Require Control (Sec. 60.782)--
Procedures for Determining Compliance (Sec. 60.783)

A. General

    Three sections of today's proposed rule, Secs. 60.779, 60.782, and 
60.783, were revised to incorporate the point of determination concept 
and to add flexibility in the compliance demonstration for facilities 
using biological treatment processes to meet the requirements of 
subpart YYY. These revisions are based mostly on the HON. Revisions to 
Sec. 60.782 include the addition of methods and an alternative 
validation procedure. The three sections referenced above are discussed 
together because a change made to one has generally also been made to 
the other sections. A specific change will be discussed where it first 
appears or has the most impact.

B. Changes to Sec. 60.779, Process Wastewater Provisions--Performance 
Standards for Treatment Processes Managing Group 1 Wastewater Streams 
and/or Residuals Removed From Group 1 Wastewater Streams

    Section 60.779 contains provisions for control of Group 1 
wastewater streams and residuals from Group 1 wastewater streams. The 
most significant changes proposed to Sec. 60.779 are: adoption of the 
Group 1/Group 2 terminology from the HON; deletion of the recycling 
control options; clarification on how to use speciated options within 
the existing compliance option framework; technical corrections to the 
design steam stripper specifications and removal of unnecessary 
specification of steam quality; clarification of compliance 
demonstration procedures that may be used for biological treatment 
processes; clarification that treatment in series is allowed; addition 
of provisions for a 1 megagram facility-wide exemption; and 
clarification of when design evaluations may be used to demonstrate 
compliance instead of performance tests.
1. Deletion of Recycling Options From Sec. 60.779
    The recycling option is unnecessary under the POD concept which 
replaces the POG concept. The recycling option allowed an owner or 
operator to achieve compliance by recycling a process stream to a 
process unit. The recycling provisions in paragraph (d) of the 
September 1994 proposed rule would have required that the wastewater or 
residual not be exposed to the atmosphere and that waste management 
units in contact with the wastewater streams or residual comply with 
control and inspection and monitoring requirements. With the proposed 
point of determination concept, the recycling option would become 
redundant because as long as a fluid stays in the process, it would not 
be a wastewater subject to the provisions of Sec. 60.779; instead, it 
would be an aqueous in-process stream subject to the provisions of 
Sec. 60.775.
2. Addition of Simplified Compliance Demonstration for Steam Strippers
    Today's revisions include a compliance option for steam strippers 
that bases compliance on three VOC--methanol, ethylene glycol monobutyl 
ether acetate, and methyl ethyl ketone. This compliance option requires 
that the Fr value, expressed as a percentage, be achieved for each of 
the three compounds. This simplifies compliance demonstration by 
requiring a demonstration for three compounds instead of up to 75 
compounds. This option could be used by a facility without identifying 
the compounds in the wastewater stream that are going to the steam 
stripper.
    The EPA has defined design and operating specifications for a steam 
stripper, called the design steam stripper. The design steam stripper 
is the basis of the wastewater control requirements. Other steam 
strippers may provide equivalent or superior performance to the design 
steam stripper. Equivalent performance to the design steam stripper can 
be demonstrated based on compounds not present in the wastewater 
stream.
    EPA chose methanol, ethylene glycol monobutyl ether acetate, and 
methyl ethyl ketone because they cover a range of volatilities. 
Methanol is only partially removed by the design steam stripper, and 
methyl ethyl ketone is removed at levels greater than 95 percent. The 
methanol removal is used to verify the steam rate. The methyl ethyl 
ketone removal is used to verify the separation performance of the 
steam stripper. The Henry's law constant of ethylene glycol monobutyl 
ether acetate is in between the Henry's law constant of methanol and 
methyl ethyl ketone. Consequently, the percent of ethylene glycol 
monobutyl ether acetate removed by the steam stripper should be in 
between the percents removed for the other two compounds. This helps 
provide verification of steam stripper performance.
    When design evaluations are used to demonstrate compliance, the 
design

[[Page 67996]]

evaluation is based on the three compounds. The proposal specifies 
Henry's law constants at a 100  deg.C, expressed in atmosphere per mole 
fraction, that must be used in the design evaluation. These Henry's law 
constants and the Fr values for each compound are listed in Table 2 of 
this preamble.
    Any computer model that can be used for accurate prediction of the 
steam stripper system of concern can be used. Depending on the 
complexity of the steam stripper system, some computer models may not 
be appropriate. Some examples of computer model failures include 
particulate buildup in the column, lack of ability to predict liquid 
phase separation, inability to partition compounds into oil and 
emulsified oil, and inadequate thermodynamic properties for the system 
of interest.

------------------------------------------------------------------------

    When performance tests are used to demonstrate compliance, if the 
wastewater stream entering the steam stripper does not contain all 
three compounds, the wastewater stream must be spiked so that the 
percent removal of the compounds can be determined.
    Today's revisions include two other compliance options that do not 
require speciation. They are the 95 percent mass removal with an outlet 
VOC concentration of 50 ppmw option and the design steam stripper 
option. EPA is aware that some in the regulated community are working 
to develop a nonspeciated method to demonstrate compliance with 
biological treatment units. If this procedure is demonstrated to be 
effective, EPA will consider adding it to these provisions.
3. Clarification That Treatment in Series is Allowed
    The September 1994 proposed rule intended that more than one 
treatment process could be used to comply with the rule. Today's 
revised proposed rule explicitly provides for treatment in series in 
Secs. 60.779 and 60.783 and clarifies EPA's intent on this issue. 
Although all Group 1 wastewater streams or residuals must be conveyed 
in controlled individual drain systems, treatment in series may be used 
whether or not treatment processes are connected by hard-piping. 
However, inlet and outlet mass flow rate determination for compliance 
demonstration differ, depending on whether hard-piping is used to 
connect treatment processes and whether a biological treatment process 
is part of the series.
4. Revised Provisions for the One Megagram Source-wide Exemption
    The provisions for the 1 megagram option were clarified and revised 
and were moved from Sec. 60.770 into Sec. 60.779. In the September 1994 
proposed rule, the 1 megagram exception could have been applied to each 
affected process at the plant site. The 1 megagram exemption in today's 
revised proposed rule is a source-wide exemption that is to be shared 
among affected facilities at the plant site. This change makes the rule 
more consistent with the HON.

C. Alternative Methods to Method 25D Used in Sec. 60.782

    Today's revised proposed rule would allow use of alternative 
methods for Group 1 or Group 2 determinations for process wastewater 
streams in lieu of Method 25D for all compliance options. The EPA 
reviewed Methods 624, 625, 1624, and 1625 and has determined that these 
methods may be used with certain additional requirements. These 
requirements are specified in Sec. 60.782(b) of today's proposed rule. 
Other methods may be used if they are validated by the Method 301 
validation procedure. EPA's review of these methods was discussed in 
section IV.F. of the HON preamble of 26 August 1996 (61 FR 43698).

D. Changes to Sec. 60.783, Process Wastewater--Test Methods and 
Procedures To Determine Compliance

    Section 60.783 indicates how to demonstrate compliance with the 
performance standards in Sec. 60.779. Several significant changes are 
proposed to this section.
1. Reorganization of Sec. 60.783
    In today's proposal, three clarifications to Sec. 60.783 are of 
particular note: (1) conditions under which a performance test or 
design evaluation is allowed or under which neither is required are 
specified in paragraphs (a)(1) and (a)(2); (2) new paragraphs (a)(3)-
(a)(7) specify the following performance test and compliance 
determination guidance: performance tests and compliance determinations 
are to be conducted according to 63.7(a) of subpart A of 40 CFR part 63 
and this subpart, the Administrator should be notified of the intention 
to conduct a performance test at least 30 calendar days before the 
performance test is scheduled, certain operating conditions apply when 
conducting tests, data should be reduced and validated, and how to 
apply for a performance test waiver; and (3) ``representative operating 
conditions'' for treatment processes and control devices are specified 
in paragraphs (a)(8) and (a)(9) of Sec. 60.783. The reorganized section 
would also make provisions for measuring concentration and flow rate 
consistent throughout the section.
2. Demonstrating Compliance for Biological Treatment Processes and 
Addition of ``Enhanced Biological Treatment Process'' Concept
    Today's revised proposed rule would add paragraph (h) which (1) 
describes how to determine the site-specific fraction of VOC 
biodegradated (Fbio); (2) clarify that biological treatment processes 
must use one of the required mass removal options to comply with the 
rule; (3) add flexibility in demonstrating compliance for biological 
treatment processes; and (4) add provisions that allow a subset of VOC 
to be used to demonstrate compliance.
    Paragraph (h)--how to determine Fbio--is added to make the 
provisions easier to locate. In addition, Sec. 60.783(h), together with 
appendix C to part 63, provide more flexibility to the owner or 
operator to demonstrate compliance for biological treatment processes. 
The September 1994 proposed rule required owners and operators using 
biological treatment processes to demonstrate compliance using appendix 
C to part 63 to determine Fbio. Today's revisions recognize that for 
some biological treatment processes, those EPA has designated 
``enhanced biological treatment processes,'' a less rigorous 
determination of Fbio is sufficient to demonstrate compliance. This 
concept is discussed below.
    When a biological treatment process is used, one of the required 
mass removal options, Sec. 60.779(f) or (g), must be chosen as the 
compliance option. The provisions that may be used to demonstrate 
compliance depend on whether the biological treatment process is open 
or closed. In each case, the proposed rule specifies which compliance 
demonstration provisions may be used.
    For open biological treatment processes, volatilization is an 
important

[[Page 67997]]

concern. Therefore, to demonstrate compliance, the owner or operator 
must determine the mass of VOC that are removed due to biodegradation 
rather than volatilization. If the open biological treatment process is 
an enhanced biological treatment process, the source would have more 
flexibility in demonstrating compliance.
3. Performance Requirements for Open Biological Treatment Processes
    Today's revised proposed rule lists 24 compounds in Table 14. This 
list of compounds would be used together with other provisions to 
specify how the source may demonstrate compliance. Table 14 may only be 
used for wastewater streams treated in an enhanced biological treatment 
system as defined by the proposed revisions to the rule. The basis of 
the list is discussed in detail in the HON preamble of 26 August 1996 
(61 FR 43698), in the HON preamble of January 17, 1997 (62 FR 2722), in 
the HON preamble of August 22, 1997 (62 FR 44608), and in Docket A-90-
23.
    A performance demonstration would not be required for enhanced 
biological treatment systems that receive wastewater streams that 
require control and that contain only Table 14 compounds. An example 
would be an activated sludge unit that meets the proposed enhanced 
biological treatment system definition and treats Group 1 wastewater 
streams that contain only methanol and nitrobenzene (proposed Table 14 
compounds). For enhanced biological treatment systems treating 
wastewater containing compounds other than those on proposed Table 14, 
a performance demonstration is required.
    Today's revisions offer several techniques for demonstrating 
compliance for an open biological treatment unit meeting the proposed 
definition of an enhanced biological treatment system. The 
demonstration is performed by estimating the Fbio for the system using 
the first order biodegradation constant (K1) and the forms in appendix 
C to part 63. The owner or operator may use any of the procedures 
specified in 40 CFR part 63, appendix C to calculate the site-specific 
K1s for VOC. The owner or operator may elect not to calculate site-
specific biodegradation rate constants but instead to calculate Fbio 
for the Table 14 compounds using the defaults for K1s in Table 14 and 
to follow the procedure explained in Form IIA of appendix C. For all 
other VOC treated in a unit meeting the definition of ``enhanced 
biological treatment system,'' the owner or operator is allowed to use 
any of the procedures specified in 40 CFR part 63, appendix C, to 
calculate the site-specific K1. Biological treatment units not meeting 
the definition of an enhanced biological treatment system are allowed 
to determine the Fbio using the site-specific K1 values determined by 
any of the procedures in appendix C to part 63 except procedure 3 
(inlet and outlet concentration measurements).
    The EPA believes that today's proposed revisions to the biological 
treatment option adds additional flexibility without sacrificing 
reduction of emissions. By separating VOC into the proposed Table 14 
compounds and all other VOC and allowing different performance 
requirements depending on the properties of the compounds on proposed 
Table 14, additional options have been made available to the owner/
operator. The flexibility allowed by not requiring that the site-
specific fraction biodegraded be determined for all VOC in the 
wastewater stream is predicated on the underlying assumption that the 
wastewater is treated in an enhanced biological treatment system.
4. Meaning of Enhanced Biological Treatment Unit
    The definition of ``enhanced biological treatment system or 
enhanced biological treatment process'' is intended to reflect the 
basis for the simplified compliance approach for some systems. The list 
of compounds in Table 14 were developed by modeling performance of an 
activated sludge system that was a thoroughly mixed biological 
treatment unit (Docket number A-90-23, item VII-B-8). The definition of 
enhanced biological treatment process includes a description of a 
``thoroughly mixed treatment unit.'' ``Thoroughly mixed treatment 
unit'' is intended to convey the concept of an activated sludge system 
that is designed and operated to approach or achieve the 
characteristics of a completely back mixed system. Because the EPA does 
not intend the definition to only allow systems with perfect uniformity 
in characteristics, a ``thoroughly mixed treatment unit'' would be 
described as a unit that is ``designed and operated to approach or 
achieve uniform biomass distribution and organic compound concentration 
throughout the aeration unit by quickly dispersing the recycled biomass 
and the wastewater entering the unit.'' This description is intended to 
recognize that well-designed complete mix systems may still have small 
insignificant stagnant zones or other minor deviations from complete 
mixing. The meaning of enhanced biological treatment system in this 
subpart is meant to be exactly the same as its meaning in the HON.
    The EPA realizes that many units have varying degrees of uniformity 
in biomass distribution and organic compound concentration throughout 
the biological unit. The EPA is developing additional information to 
assist in determining whether a biological treatment unit is thoroughly 
mixed and meets the enhanced biological treatment system definition. 
When finished, the additional information will be available from the 
Air and Radiation Docket and Information Center and on the EPA's 
Technology Transfer Network (TTN).
5. Equations in Sec. 60.783
    Many of the equations in Sec. 60.783 were revised to make 
mathematical corrections or to make the equations consistent with the 
rest of the rule and with the HON. The terms in the equations were 
changed to make them consistent as well.
6. Compounds not Required To Be Considered in Performance Tests
    Today's revised proposed rule adds Sec. 60.783(a)(6) which 
specifies when compounds can be excluded from in a performance test. 
These provisions were added because EPA recognizes that not all VOC are 
present in a wastewater stream; and not all compounds need to be 
measured to demonstrate compliance, i.e., measuring a predominant 
compound may be enough to show the mass removal necessary to achieve 
compliance. These provisions would also provide that compounds present 
at concentrations less than 1 ppmw at the POD or compounds present at 
the POD at concentrations less than the lower detection limit where the 
lower detection limit is greater than 1 ppmw may be excluded from the 
performance test. This provision was added to avoid imposing an 
unnecessary analytical burden.

XII. Revisions to Requirements for Delay of Repair (Sec. 60.777) 
and Control Devices (Sec. 60.780)

    Today's revised proposed rule changes the control device provisions 
in Sec. 60.780. The delay of repair provisions previously included in 
this section have been moved to Sec. 60.777. The delay of repair 
provisions in Sec. 60.777 reflect changes and clarifications made to 
the HON delay of repair provisions for process wastewater in the 
January 17, 1997 HON rule amendments. The revised provisions allow 
delay of repair for any of the following situations: (1) the repair is 
technically infeasible without a shutdown, or the emissions of purged 
material from immediate repair

[[Page 67998]]

would be greater than emissions likely to result from delay of repair, 
(2) the equipment has been emptied or is no longer used to treat or 
manage Group 1 wastewater streams, and (3) additional time is necessary 
to obtain parts.

XIII. Revisions to Requirements for Inspections and Monitoring 
(Sec. 60.781)

    Today's revised proposed rule changes the inspection and monitoring 
provisions in Sec. 60.781. The changes clarify that for each excursion, 
except for excused excursions, the owner or operator has failed to 
apply control in a manner that achieves the required operating 
conditions. Failure to achieve the required operating conditions is a 
violation of the standard.

XIV. Revisions to Reporting Requirements (Sec. 60.784)

    Today's revised proposed rule changes the reporting provisions in 
Sec. 60.784. These changes are consistent with the reporting provisions 
in the HON rule. Significant changes proposed include: allowing 
alternative monitoring and recordkeeping systems, including non-
automated systems and data compression systems; clarifying that only 
one excursion per control device per day can occur; the addition of one 
excused excursion per control device per semiannual period; 
clarification of monitoring parameter value violations; and the 
addition of a report name, the Notification of Compliance Status, to 
describe compliance demonstration information that must be reported.

A. Alternative Monitoring and Recordkeeping Systems

    Today's revised proposed rule would allow owners or operators the 
option to request approval to use alternative monitoring and 
recordkeeping systems. This change will allow owners or operators to 
use existing systems. Alternative monitoring systems specifically 
discussed in the rule include non-automated systems and data 
compression systems. These systems will be allowed on a site-specific 
basis and requests for approval of alternative monitoring must be 
submitted prior to the implementation of the alternative monitoring 
system for which approval is being requested.
    Another type of alternative monitoring system allows reduced 
recordkeeping. Under this alternative, the owner or operator may use a 
monitoring system capable of detecting unrealistic or impossible data. 
The monitoring system must be equipped with an alarm or other means for 
alerting the owner or operator when unrealistic or impossible data is 
generated. Use of such a monitoring system allows the owner or operator 
to retain only the daily average value and would not require retention 
of more frequent monitored operating parameter values. Additional 
monitoring system requirements and recordkeeping requirements for this 
program are specified in Sec. 60.785.
    If after 6 months no excursions have occurred, the owner or 
operator is no longer required to record the daily average value for 
any operating day when the daily average value is less than the maximum 
or greater than the minimum established limit. If an excursion occurs 
after the owner or operator has ceased recording daily average values, 
the owner or operator must resume retaining the daily average value for 
each operating day until another period of 6 consecutive months has 
passed without an excursion.

B. One Excursion per Control Device

    Commenters requested that the rule specifically state that not more 
than one excursion per control device per operating day is possible. 
The rule was clarified to say that if one parameter meets the excursion 
criteria of the rule, then that is considered a single excursion for 
the control device. If the control device has multiple parameters that 
are monitored, and more than one of the parameters meets the excursion 
criteria, it is still considered a single excursion for the control 
device.

C. Excused Excursions

    Commenters stated that excused excursions were necessary to account 
for the inevitable and unanticipated operating parameter fluctuations 
that occur during normal operation of control devices. The commenters 
stated that a certain number of excursions could be expected even with 
properly operated pollution control devices. The proposed rule requires 
the owner or operator to record a daily average for each control device 
with continuously monitored parameters. The EPA is proposing to allow 
one excused excursion per control device per six month reporting 
period. Excused excursions may be appropriate when a technology 
standard, such as the standard mandated in section 111 of the CAA, is 
predicated on the best demonstrated control. EPA has determined that 
even properly operated and maintained control equipment may not perform 
perfectly over time and that this may be taken into account when 
determining best demonstrated control.
    The proposed one excused excursion per semiannual reporting period 
equates to roughly one-half percent of the days in the reporting 
period. As discussed in the HON preamble, the time allowed as excused 
excursions was selected based on information about the types of events 
that cause parameter excursions; the duration of the typical 
excursions; and, the frequency of the events that create excursions. In 
addition, the proposed approach to excused excursions would provide 
consistency with the HON.
    Examples of events that could cause excursions that would count 
toward the number of excused excursions are as follows: a thermocouple 
failure in an incinerator; water contamination in a condenser; off-
specification feedstocks; electrical problems; control valve problems 
such as leaky pneumatic drivers; and extreme environmental conditions. 
Events that are considered malfunctions under the Start-up, Shut-down, 
and Malfunction Plan required by this subpart are to be handled 
separately and would not be counted toward the allowed number of 
excused excursions. In addition, the provisions for excused excursions 
are not meant to allow actions that are specifically disallowed by 
other sections of the NSPS or the General Provisions, such as bypass of 
a control device.

D. Monitoring Parameter Value Violations

    Under earlier NSPS and NESHAP programs, parameter monitoring has 
traditionally been used as a tool in determining whether control 
devices are being maintained and operated properly. However, section 
114(a)(3) of the Act and Sec. 70.6(c) of the operating permit rule (57 
FR 32251, July 21, 1992) require the submissions of ``compliance 
certifications'' from sources subject to the operating permit program. 
Affected facilities would be subject to the operating permit program. 
Sources must certify whether compliance was continuous or intermittent, 
as well as their compliance status at the end of the reporting period. 
In light of these requirements, the Agency has considered how sources 
subject to this rule would demonstrate compliance.
    EPA has considered several approaches for monitoring requirements 
and has determined that one or more continuous monitoring systems 
provide the best compliance assurance. EPA has developed a hierarchy 
for selecting monitoring requirements. The hierarchy is: (1) continuous 
emissions monitoring; (2) continuous emissions monitoring for surrogate 
emissions; (3) operating parameters monitoring; and, (4) work practice 
requirements. The choice of monitoring system selected should be based 
on availability, cost, and effectiveness.

[[Page 67999]]

    For many waste management units, today's revisions specify good 
work practices, including periodic inspections. For control devices and 
treatment processes, today's revisions either specify, or require the 
owner or operator to establish appropriate monitoring parameter values.
    Today's revisions specify that operating above the approved maximum 
value or below the approved minimum value for monitoring parameter 
values is a violation of the standard.

E. Notification of Compliance Status

    The term ``Notification of Compliance Status'' has been added to 
the rule to provide a report name for compliance demonstration 
information that must be submitted to the EPA. Most of the information 
required to be submitted in the Notification of Compliance Status was 
already required under the September 1994 proposed rule. Types of 
information that would be included in the Notification of Compliance 
Status include results of emission point group determinations, 
performance tests, inspections, continuous monitoring system 
performance evaluations, values of monitored parameters established 
during performance tests, and other information used to demonstrate 
compliance. The Notification of Compliance Status is a one time report 
submitted for each affected facility. The term ``Notification of 
Compliance Status'' was chosen because it is also used in the HON.
    In addition, the rule was revised to clarify that when performance 
tests and group determinations based on measurements are performed, 
only one complete test report is necessary for each test method used 
for a particular kind of emission point. Results and other required 
information still must be submitted.
    A time frame for submittal of the Notification of Compliance Status 
was added to the rule. The rule was revised to say that the 
Notification of Compliance Status is due within 150 days after the 
compliance dates for the rule. This time frame is consistent with the 
time frame for the Notification of Compliance Status in the HON.
    Tables 9 through 12 were also revised to reflect changes made to 
the HON tables and to require that the information in the tables be 
submitted as part of the Notification of Compliance Status. Tables 5, 
7, 8, and 13 were also revised to reflect HON table changes.

XV. Revisions to Recordkeeping Requirements (Sec. 60.785)

    Today's revised proposed rule changes the recordkeeping provisions 
in Sec. 60.785. The changes clarify the periods during which monitoring 
data should not be included in the daily average: monitoring system 
breakdowns, repairs, calibration checks, and zero (low-level) and high-
level adjustments; start-ups; shutdowns; malfunctions; periods of non-
operation of the chemical process unit (or portion thereof), resulting 
in cessation of the emissions to which the monitoring applies.
    The EPA also added data retention provisions. Under these 
provisions, records and reports required by the rule must be kept and 
must be accessible for 5 years.
    Provisions for keeping continuous records and calculating daily 
averages have been clarified in the proposed rule. Provisions were 
added to clarify the frequency with which monitoring systems should 
record data and which of this data are necessary to demonstrate 
continuous compliance. The provisions require the monitoring system to 
measure data values at least once every 15 minutes. Each measured data 
value or block average values for 15-minute or shorter periods are used 
to calculate hourly average data values. The hourly average values are 
used to calculate daily average values. For days when all recorded 
values for a monitored parameter are below the minimum or above the 
maximum established value, the owner or operator may record that all 
values were below the maximum or above the minimum established 
operating parameter value. The 15-minute value must be retained for 
operating days when the daily average value of the monitored parameter 
is above the maximum or below the minimum established value. These 
provisions are consistent with the continuous record provisions in the 
HON.

XVI. Revisions to Additional Requirements--Start-up, Shutdown, 
Malfunction, and Non-Operation, and Alternative Means of Emission 
Limitation, and Permits (Sec. 60.787)

    Today's revised proposed rule adds provisions for proper operation 
and maintenance of the affected facility during periods of start-up, 
shutdown, malfunction, and non-operation. The provisions require that 
the owner or operator of each affected facility develop a written 
start-up, shutdown, and malfunction plan, to be kept on-site, which 
would describe procedures for operating and maintaining the affected 
facility during periods of start-up, shutdown, and malfunction, and a 
program for corrective action for malfunctioning process and air 
pollution control equipment used to comply with this subpart. 
Appropriate reporting and recordkeeping of periods of start-up, 
shutdown, and malfunction are specified in this section. This change 
makes the rule more consistent with the HON.
    New provisions have also been added for approval of an alternative 
means of emission limitation if the alternative achieves a reduction in 
VOC emissions at least equivalent to the reduction achieved under this 
subpart. Approved alternatives are published in the Federal Register. 
This change makes the rule more consistent with the HON.
    Provisions directing owners or operators to obtain a permit under 
the operating permit program are also included in this section.

XVII. Revisions to Leak Inspection Requirements (Sec. 60.786)

    Today's revised proposed rule changes the leak inspection 
provisions in Sec. 60.786. These changes mirror the changes made to 
Sec. 63.148, Leak inspection provisions, of the HON rule in the January 
17, 1997 amendments (62 FR 2775).

XVIII. Revisions to List of SOCMI Chemicals (Table 1)

    EPA reviewed the list of proposed SOCMI chemicals on Table 1 of the 
rule and made spelling corrections and removed some duplicate 
compounds. EPA is considering removing other chemicals from Table 1 and 
requests comment on whether any chemicals should be added to or deleted 
from Table 1.

XIX. Addition of Appendix J to Part 60

    Today's revised proposed rule adds Appendix J to part 60, How to 
Determine Henry's Law Constants, Fm Values, Fr Values, and Fe Values 
for Organic Compounds. This appendix provides the methodology for 
determining Henry's law constants, fraction measured (Fm) values, 
fraction removed values (Fr), and fraction emitted (Fe) values.
    The development of these values is discussed in ``Correction to the 
report dated February 2, 1994 ``Estimation of Air Emissions from model 
wastewater collection and treatment plants'' and ``Estimation of 
Compound Properties: Correlations for Fm, Fr, Fe, and Fet.'' (Docket 
item A-90-23, IV-B-4 and Docket item A-94-32, IV-A-1)
    The proposed appendix has four sections. Section 2 contains the 
procedures for determining Henry's law constants, Fm values, Fr values, 
and Fe values. Section 3 describes how to

[[Page 68000]]

locate certain resources. Section 4 contains five tables and thirteen 
forms.
    The appendix would be used to:
    1. Determine whether a chemical has a Henry's law constant at 
25 deg. C that is less than 0.1 y/x atmosphere per mole fraction.
    2. Determine a fraction measured (Fm) value for a chemical.
    3. Subtract the concentration of a chemical from a Method 25D 
concentration.
    4. Determine the fraction removed (Fr) value for a chemical that 
has a Henry's law constant at 25 deg. C that is greater than or equal 
to 0.1 y/x atmosphere per mole fraction.
    5. Determine the fraction emitted (Fe) value for a chemical that 
has a Henry's law constant at 25 deg. C that is greater than or equal 
to 0.1 y/x atmosphere per mole fraction.
    6. Calculate a Henry's law constant at a specific temperature using 
a Henry's law constant at a different temperature for the same 
chemical.

XX. Administrative Requirements

A. Paperwork Reduction Act

    The information collection requirements in this proposed rule have 
been submitted for approval to the Office of Management and Budget 
(OMB) under the Paperwork Reduction Act, 44 U.S.C. 3501 et seq. An 
Information Collection Request (ICR) document has been prepared by EPA 
(ICR No. 1697.02) and a copy may be obtained from Sandy Farmer, 
Regulatory Information Division; U.S. Environmental Protection Agency 
(2137); 401 M St., SW; Washington, DC 20460 or by calling (202) 260-
2740.
    Information will be collected as required in the General Provisions 
to part 60 and the requirements in the reporting and recordkeeping 
sections of the proposed rule. The information will be used to ensure 
compliance with the standard.
    The changes included in today's revised proposed rule do not affect 
the information collection burden estimates prepared for the September 
1994 proposal. The changes consist of revised definitions, alternative 
test procedures, and clarifications of requirements. The proposed 
changes do not include new or additional requirements. Consequently, 
the ICR has not been revised for this rule, although it has been 
resubmitted to OMB.
    The estimated annual cost and hour burden per respondent is about 
$4,830 and 150 hours, per respondent. Burden means the total time, 
effort, or financial resources expended by persons to generate, 
maintain, retain, or disclose or provide information to or for a 
federal agency. This includes the time needed to review instructions; 
develop, acquire, install, and use technology and systems for the 
purposes of collecting, validating, and verifying information, 
processing and maintaining information, and disclosing and providing 
information; adjust the existing ways to comply with any previously 
applicable instructions and requirements; train personnel to be able to 
respond to a collection of information; search data sources; complete 
and review the collection of information; and transmit or otherwise 
disclose the information.
    An agency may not conduct or sponsor, and a person is not required 
to respond to, a collection of information unless it displays a 
currently valid OMB control number. The OMB control numbers for the 
EPA's regulations are listed in 40 CFR part 9 and 48 CFR Chapter 15.
    The Agency requests comments on the need for this information, the 
accuracy of the provided burden estimates, and any suggested methods 
for minimizing the respondent burden, including through the use of 
automated collection techniques. Send comments on the ICR to the 
Director, Regulatory Information Division; U.S. Environmental 
Protection Agency (2137); 401 M St., S.W.; Washington, D.C. 20460; and 
to the Office of Information and Regulatory Affairs, Office of 
Management and Budget, 725 17th St., N.W., Washington, D.C. 20503, 
marked ``Attention: Desk Officer for EPA.'' Include the ICR number in 
any correspondence. Since OMB is required to make a decision concerning 
the ICR between 30 and 60 days after [insert date of publication in 
Federal Register], a comment to OMB is best assured of having its full 
effect if OMB receives it by [insert date 30 days after publication in 
the Federal Register]. The final rule will respond to any OMB or public 
comments on the information collection requirements contained in this 
proposal.

B. Executive Order 12866 Review

    Under Executive Order 12866, the EPA must determine whether the 
proposed regulatory action is ``significant'' and, therefore, subject 
to OMB review and the requirements of the Executive Order. The Order 
defines ``significant'' regulatory action as one that is likely to lead 
to a rule that may:
    (1) Have an annual effect on the economy of $100 million or more or 
adversely affect in a material way the economy, a sector of the 
economy, productivity, competition, jobs, the environment, public 
health or safety in State, local, or tribal governments or communities;
    (2) create a serious inconsistency or otherwise interfere with an 
action taken or planned by another agency;
    (3) materially alter the budgetary impact of entitlements, grants, 
user fees, or loan programs or the rights and obligations of recipients 
thereof; or
    (4) raise novel legal or policy issues arising out of legal 
mandates, the President's priorities, or the principles set forth in 
the Executive Order.
    The September 1994 proposal was considered ``not significant'' 
under Executive Order 12866. The revisions proposed today clarify the 
September 1994 proposed rule. As revised the proposed rule does not add 
any new control requirements. Therefore, this regulatory action is 
considered ``not significant'' and was not reviewed by OMB.

C. Regulatory Flexibility

    The Regulatory Flexibility Act (RFA) provides that, whenever an 
agency promulgates a proposed rule under 5 U.S.C. Sec. 553, an agency 
must prepare an initial regulatory flexibility analysis unless the head 
of the agency certifies that the proposed rule will not have a 
significant economic impact on a substantial number of small entities. 
The EPA has evaluated the impact of this proposed regulation on small 
entities. Based upon the analysis, and pursuant to section 605(b) of 
the Regulatory Flexibility Act, 5 U.S.C. 605 (b), I certify that this 
rule will not have a significant impact on a substantial number of 
small entities.
    The SOCMI Wastewater NSPS applies to new and modified sources. 
Existing sources may be subject to the NSPS in the event these 
facilities are modified. Since the regulation is applicable to new 
sources or existing sources that modify facilities, the actual entities 
impacted by the regulation are not known precisely. This is 
particularly true with regard to new sources. Due to the difficulties 
in predicting those facilities that will be subject to the rule, the 
EPA looked at two data sources for information: the regulatory 
flexibility analysis performed for the HON and the SOCMI wastewater 
database.
    The EPA analyzed SOCMI for impacts on small business when the HON 
was developed. Since the HON and the SOCMI wastewater NSPS will affect 
the same and similar facilities and the emission control requirements 
are similar, the EPA believes that the analysis done for the HON is 
valid for this rule as well. The HON analysis, which was based on 66 
firms, concluded that fewer than 15 percent of

[[Page 68001]]

the firms were small firms and that they do not constitute a 
substantial number. Furthermore, the economic analysis for the HON 
projected generally small impacts (87 percent of the analyzed sample 
were projected to have output changes of less than 2 percent). 
Therefore, the HON was not expected to have a significant economic 
impact on a substantial number of small firms. The regulatory 
flexibility analysis for the HON is discussed in 59 FR 19449 (April 22, 
1994).
    The EPA next considered a database created from surveys sent to 
industry under the authority of section 114 of the Act. This database, 
called the SOCMI 114 database, includes information on SOCMI-generated 
wastewater streams. The EPA used the database as another way to assess 
potential impacts on small entities.
    The 25 facilities in the SOCMI 114 database used to make this 
assessment are owned by 9 companies. All of these facilities produce 
chemicals in either Standard Industrial Classification (SIC) 2869 
(Industrial Chemicals, N.E.C.) or SIC 2821 (Plastic Materials, 
Synthetic Resins, and Nonvulcanizable Elastomers). The Small Business 
Administration (SBA) defines a small business for SIC 2869 and SIC 2821 
to be companies with less than 1000 and 750 employees, respectively. 
Each of the 9 companies in the SOCMI 114 database are not small 
businesses within the SBA definition. Based upon this database, no 
small businesses are expected to be directly impacted by the SOCMI 
Wastewater NSPS. The economic impacts of this regulation for the 
facilities in the SOCMI 114 database are also anticipated to be minimal 
with price and quantity impacts of less than 1 percent.
    The small business analysis conducted for this regulation indicates 
that companies potentially affected by the NSPS are large companies 
(SOCMI 114 database) or are not anticipated to be significantly 
impacted by the regulation (HON regulatory flexibility analysis). Thus, 
the EPA concludes that this regulation will not have a significant 
impact on a substantial number of small entities as specified in the 
RFA.

D. Unfunded Mandates Reform Act

    Under Section 202 of the Unfunded Mandates Reform Act of 1995 
(Unfunded Mandates Act), the EPA must prepare a budgetary impact 
statement to accompany any proposed or final rule that includes a 
Federal mandate that may result in estimated costs to State, local, or 
tribal governments in the aggregate or to the private sector, of $100 
million or more in any one year. Under Section 205, the EPA must select 
the least costly, most cost-effective, or least burdensome alternative 
that achieves the objectives of the rule and is consistent with 
statutory requirements. Section 203 requires the EPA to establish a 
plan for informing and advising any small governments that may be 
significantly or uniquely impacted by the rule. The EPA has determined 
that today's proposed rule contains no regulatory requirements that 
might significantly or uniquely affect small governments.
    The EPA has determined that today's proposed rule does not include 
a Federal mandate that may result in estimated costs of $100 million or 
more to either State, local, or tribal governments in the aggregate or 
to the private sector. Therefore, the requirements of the Unfunded 
Mandates Act do not apply to this action.

E. Executive Orders 12875 and 13084

    Today's action does not impose any unfunded mandate upon any State, 
local, or tribal government; therefore, Executive Orders 12875 and 
13084 do not apply to this rulemaking.
    Under E.O. 12875 and E.O. 13084, EPA may not issue a regulation 
that is not required by statute and that creates a mandate upon a 
State, local or Tribal government unless the Federal Government 
provides the necessary funds to pay the direct costs incurred by the 
State, local or Tribal government or EPA provides to the Office of 
Management and Budget a description of the extent of the prior 
consultation and written communications with representatives of 
affected State, local and Tribal governments and an Agency statement 
supporting the need to issue the regulation. In addition, E.O. 12875 
and E.O. 13084 require EPA to develop an effective process permitting 
elected officials and other representatives of State, local and Tribal 
governments ``to provide meaningful and timely input in the development 
of regulatory proposals containing significant unfunded mandates.''

F. National Technology Transfer and Advancement Act

    Section 12(d) of the National Technology Transfer and Advancement 
Act of 1995 (the NTTAA), Pub. L. No. 104-113, sec. 12(d) (15 U.S.C. 272 
note), directs EPA to use voluntary consensus standards in its 
regulatory activities unless to do so would be inconsistent with 
applicable law or otherwise impractical. Voluntary consensus standards 
are technical standards (e.g., materials specifications, test methods, 
sampling procedures, business practices, etc.) that are developed or 
adopted by voluntary consensus standard bodies. The NTTAA requires EPA 
to provide Congress, through OMB, explanations when the Agency decides 
not to use available and applicable voluntary consensus standards.
    This proposed rulemaking includes technical standards and 
requirements for taking measurements. Consequently, the EPA searched 
for applicable voluntary consensus standards by searching the National 
Standards System Institute (NSSN) database. The NSSN is an automated 
service provided by the American National Standards Institute for 
identifying available national and international standards.
    EPA searched for methods and tests required by this proposed rule, 
all of which are methods or tests previously promulgated. The proposed 
rule includes methods that measure: (1) Volatile organic compound 
concentration in wastewater (EPA Methods 25D, 305, 624, 625, 1624, or 
1625); (2) biodegradation rates (EPA Methods 304A and B, aerated 
reactor test (i.e., BOX test) serum bottle test, performance data with 
and without biodegradation, or inlet and outlet concentration 
measurements); (3) vapor leak detection (EPA Method 21); (4) volatile 
organic compound concentration in vented gas stream (EPA Method 18); 
(5) volumetric flow rate of the vented gas stream (EPA Methods 2, 2A, 
2C, or 2D); (6) sampling site location (Method 1 or 1A); (7) validation 
of chemical methods (EPA Method 301); (8) determination of actual 
oxygen concentration (percent O2d) (EPA Method 3B); and (9) visible 
emissions (EPA Method 22). These EPA methods are found in Appendix A to 
parts 60, 63, and 136. The biodegradation tests are found in Appendix C 
to part 63.
    Except for EPA Methods 2 and 2C (Appendix A to part 60), no other 
potentially equivalent methods for the methods and tests in the 
proposal were found in the NSSN database search. EPA identified one 
Chinese (Taiwanese) National Standard (CNS) which may potentially be an 
equivalent method to EPA Methods 2 and 2C. The CNS method is CNS K9019 
for measuring velocity and flow rates in stack gases.
    However, EPA does not believe that CNS K9019 is a voluntary 
consensus method. It is unlikely that CNS K9019 was considered by 
industry groups or national setting standards organizations because it 
was not developed in the United States (U.S.) and there is no available 
information about it in the U.S.

[[Page 68002]]

    To confirm EPA's belief, EPA is asking for comment on whether any 
U.S. industry has adopted CNS K9019 as a voluntary consensus method. 
EPA is also asking for comment on whether any potential voluntary 
consensus methods exist that could be allowed in addition to the 
methods in the proposal. Methods submitted for evaluation should be 
accompanied with a basis for the recommendation, including method 
validation data and the procedure used to validate the candidate method 
(if a method other than Method 301, 40 CFR part 63, Appendix A was 
used).

G. Executive Order 13045

    This proposed rule is not subject to Executive Order 13045 (E.O. 
13045), entitled ``Protection of Children from Environmental Health 
Risks and Safety Risks'' (62 FR 19885, April 23, 1997), because this is 
not an economically significant regulatory action as defined by 
Executive Order 12866 (E.O. 12866).
    The E.O. 13045 applies to any rule that EPA determines (1) 
``economically significant'' as defined under E.O. 12866, and (2) the 
rule has a disproportionate effect on children. If the regulatory 
action meets both criteria, the Agency must evaluate the environmental 
health or safety effects of the planned rule on children and explain 
why the planned regulation is preferable to other potentially effective 
and reasonably feasible alternatives considered by the Agency.

Subpart YYY--Standards of Performance for Volatile Organic Compound 
(VOC) Emissions from Synthetic Organic Chemical Manufacturing 
Industry (SOCMI) Wastewater


Sec. 60.770  Applicability and date of compliance.

    (a) The provisions of this subpart apply to each affected facility 
and any devices or systems required by this subpart. An affected 
facility is a designated chemical process unit (CPU) in the synthetic 
organic chemical manufacturing industry which commences or commenced 
construction, reconstruction or modification after September 12, 1994. 
An affected facility that does not generate a process wastewater 
stream, a maintenance wastewater stream, or an aqueous in-process 
stream, is not subject to the control requirements of this subpart.
    (1) Initial determination of applicability. Determine applicability 
to this subpart as specified in paragraphs (b) through (g) of this 
section. For an affected facility, determine if the affected facility 
generates a process wastewater stream, maintenance wastewater stream, 
or aqueous in-process stream as specified in paragraph (h) of this 
section. The owner or operator of an affected facility that generates a 
process wastewater stream, a maintenance wastewater stream, or an 
aqueous in-process stream shall comply with requirements of this 
subpart. The owner or operator of an affected facility that does not 
generate a process wastewater stream, a maintenance wastewater stream, 
or an aqueous in-process stream is exempt from the requirements 
specified in this subpart, except for the requirements specified in 
Sec. 60.770(a)(2), Sec. 60.770(h)(2), Sec. 60.784(d)(12), and 
Sec. 60.785(c)(8) of this subpart.
    (2) Reevaluation of applicability criteria. When one or both of the 
applicability criteria in paragraph (a)(2)(i) or (a)(2)(ii) of this 
section changes, the owner or operator shall reevaluate the 
applicability as specified in this paragraph (a). A CPU or designated 
CPU shall not be evaluated more than once every 12 months. If the

[[Page 68003]]

designated CPU is an affected facility and subject to the provisions of 
this subpart, the owner or operator may elect not to reevaluate 
applicability.
    (i) Produces SOCMI as a primary product. If a CPU begins 
manufacturing chemicals not used in the primary product determination 
or ceases manufacturing chemicals listed in the primary product 
determination, the primary product determination is no longer in effect 
and shall be reevaluated as specified in paragraph (f) of this section.
    (ii) Is Modified or Reconstructed. If a designated CPU that is not 
an affected facility is modified or reconstructed after September 12, 
1994, then the applicability determination shall be evaluated as 
specified in Sec. 60.772 of this subpart.
    (3) Each affected facility shall be in compliance with the 
provisions of this subpart no later than initial start-up or [DATE OF 
PUBLICATION OF FINAL RULE], whichever is later.
    (b) The designated CPU is in the synthetic organic chemical 
manufacturing industry (SOCMI) if the conditions of either paragraph 
(b)(1) or (b)(2) of this section are met.
    (1) The designated CPU is a combination of all process lines within 
a CPU, i.e., an entire CPU, and the primary product of the designated 
CPU is a SOCMI chemical; or
    (2) The designated CPU is a process line, or combination of process 
lines within a CPU, and the primary product of the CPU is a SOCMI 
chemical.
    (3) The primary product of a CPU shall be determined as provided in 
paragraph (f) of this section.
    (4) The SOCMI chemicals are listed in Table 1 of this subpart.
    (5) Each storage vessel that is part of the CPU shall be assigned 
to one designated CPU that it services. Storage vessels shall be 
assigned to the CPU as specified in paragraph (g) of this section.
    (c) The designated CPU shall be an entire CPU except as otherwise 
provided in this paragraph (c).
    (1) The owner or operator may designate each process line or 
combination of process lines within a CPU to be a designated CPU for 
purposes of this subpart, at any time before commencing construction, 
reconstruction or modification.
    (i) If the owner or operator designates each process line, or 
combination of process lines, within a CPU to be a designated CPU, the 
installation of an additional process line may constitute construction 
of a designated CPU, but shall not in itself be considered modification 
or reconstruction of the existing process lines.
    (ii) If the entire CPU is the designated CPU, the installation of 
an additional process line may constitute modification or 
reconstruction of the designated CPU, but shall not in itself be 
considered construction of a designated CPU.
    (2) The owner or operator shall assign all equipment that is part 
of the CPU to one or more designated CPU.
    (3) Any designation under paragraph (c)(1) of this section shall be 
reported to the Administrator as provided in Sec. 60.784 of this 
subpart and shall be irrevocable.
    (d) General Provisions applicability. The owner or operator shall 
comply with the provisions of subpart A of this part and subpart A of 
40 CFR part 63 as specified in Table 2 and 2A of this subpart.
    (e) The provisions of this subpart do not apply to the processes 
listed in paragraphs (e)(1) through (e)(5) of this section. This 
subpart does not require these processes to comply with the provisions 
of subpart A of this part.
    (1) Research and development facilities.
    (2) Petroleum refining process units, regardless of whether the 
units supply feedstocks that include chemicals listed in Table 1 of 
this subpart to chemical process units that are subject to the 
provisions of this subpart.
    (3) Chemical process units that are located in coke by-product 
recovery plants.
    (4) Solvent reclamation, recovery, or recycling operations at a 
hazardous waste treatment, storage, and disposal facility (TSDF) 
requiring a permit under 40 CFR part 270 that are not part of a SOCMI 
chemical process unit.
    (5) Organic chemicals extracted from natural sources or totally 
produced from biological synthesis, such as pinene, coconut oil acids, 
sodium salt, fatty acids, tall oil, tallow acids, potassium salt, and 
beverage alcohol.
    (f) Primary product determinations. The primary product of a CPU is 
determined according to the procedures specified in paragraphs (f)(1) 
and (f)(2) of this section. With respect to CPU for which the expected 
use is known, the owner or operator shall use paragraph (f)(1) of this 
section. With respect to CPU for which the expected use is unknown, the 
owner or operator shall use paragraph (f)(2) of this section.
    (1) Expected use is known. The primary product determination for a 
CPU, where the expected use is known for the 12 months following 
initial startup shall be determined according to the procedures in 
paragraphs (f)(1)(i) through (f)(1)(iii) of this section.
    (i) If a chemical process unit produces none of the chemical 
products listed in Table 1 of this subpart, the primary product is not 
a SOCMI product.
    (ii) If a chemical process unit produces only chemical products 
listed in Table 1 of this subpart, the primary product is a SOCMI 
product.
    (iii) If a chemical process unit produces one or more chemical 
products listed in Table 1 of this subpart and one or more chemical 
products not listed in Table 1 of this subpart, the owner or operator 
shall sum the expected annual production, on a mass basis, for the 
chemical products listed in Table 1 of this subpart and sum the 
expected annual production, on a mass basis, for the chemical products 
not listed in Table 1 of this subpart. If the sum of the chemical 
products listed in Table 1 of this subpart is greater than or equal the 
sum of the chemical products not listed in Table 1 of this subpart, the 
primary product is a SOCMI product. If not, the primary product is not 
a SOCMI product.
    (2) Expected use is unknown. Where the expected use of the CPU is 
unknown for the 12 months following initial startup and the CPU will 
manufacture one or more of the chemical products listed in Table 1 of 
this subpart, the primary product of the CPU is a SOCMI product.
    (g) Storage vessel assignment. The owner or operator shall follow 
the procedures specified in paragraphs (g)(1) through (g)(4) of this 
section to determine whether a storage vessel is part of the CPU to 
which this subpart applies, either in part or in whole.
    (1) Where a storage vessel is dedicated to a chemical process unit, 
the storage vessel shall be considered part of that chemical process 
unit.
    (2) If a storage vessel is not dedicated to a single chemical 
process unit, then the applicability of this subpart shall be 
determined according to the provisions in paragraphs (g)(2)(i) through 
(g)(2)(iii) of this section.
    (i) If a storage vessel is shared among chemical process units and 
one of the process units has the predominant use, as determined by 
paragraphs (g)(2)(i)(A) and (g)(2)(i)(B) of this section, then the 
storage vessel is part of that chemical process unit.
    (A) If the greatest input into the storage vessel is from a 
chemical process unit that is located on the same plant site, then that 
chemical process unit has the predominant use.
    (B) If the greatest input into the storage vessel is provided from 
a chemical process unit that is not located

[[Page 68004]]

on the same plant site, then the predominant use is the chemical 
process unit on the same plant site that receives the greatest amount 
of material from the storage vessel.
    (ii) If a storage vessel is shared among chemical process units so 
that there is no single predominant use, and at least one of those 
chemical process units is subject to this subpart, in part or whole, 
the storage vessel shall be considered to be part of the chemical 
process unit that is subject to this subpart, in part or whole. If more 
than one chemical process unit is subject to this subpart, in part or 
whole, the owner or operator may assign the storage vessel to any of 
the chemical process units subject to this subpart.
    (iii) If the predominant use of a storage vessel varies from year 
to year, then the applicability of this subpart shall be determined 
based on the use that occurred during the year preceding [date final 
rule is published]. This determination shall be reported as part of an 
operating permit application or as otherwise specified by the 
permitting authority.
    (3) Where a storage vessel is located at a plant site that includes 
one or more chemical process units which place material into, or 
receive materials from the storage vessel, but the storage vessel is 
located in a tank farm (including a marine tank farm), the 
applicability of this subpart shall be determined according to the 
provisions in paragraphs (g)(3)(i) through (g)(3)(iv) of this section.
    (i) The storage vessel may only be assigned to a chemical process 
unit that utilizes the storage vessel and does not have an intervening 
storage vessel for that product (or raw material, as appropriate). With 
respect to any chemical process unit, an intervening storage vessel 
means a storage vessel connected by hard-piping to the chemical process 
unit and to the storage vessel in the tank farm so that product or raw 
material entering or leaving the chemical process unit flows into (or 
from) the intervening storage vessel and does not flow directly into 
(or from) the storage vessel in the tank farm.
    (ii) If there is no chemical process unit at the plant site that 
meets the criteria of paragraph (g)(3)(i) of this section with respect 
to a storage vessel, this subpart does not apply to the storage vessel.
    (iii) If there is only one chemical process unit at the plant site 
that meets the criteria of paragraph (g)(3)(i) of this section with 
respect to a storage vessel, the storage vessel shall be assigned to 
that chemical process unit.
    (iv) If there are two or more chemical process units at the plant 
site that meet the criteria of paragraph (g)(3)(i) of this section with 
respect to a storage vessel, the storage vessel shall be assigned to 
one of those chemical process units according to the provisions of 
paragraph (g)(2) of this section. The predominant use shall be 
determined among only those chemical process units that meet the 
criteria of paragraph (g)(3)(i) of this section.
    (4) If the storage vessel begins receiving material from (or 
sending material to) another chemical process unit, or ceasing to 
receive material from (or send material to) a chemical process unit, or 
if there is a significant change in the use of a storage vessel whose 
predominant use was determined according to paragraph (g)(2)(i) of this 
section that could reasonably change the predominant use, the owner or 
operator shall reevaluate the applicability of this subpart to the 
storage vessel.
    (h) Process Wastewater, maintenance wastewater, and aqueous in-
process stream determination. 
    (1) The owner or operator shall determined whether an affected 
facility generates a process wastewater stream, a maintenance 
wastewater stream, or an aqueous in-process stream. The owner or 
operator of an affected facility that generates a process wastewater 
stream, maintenance wastewater stream, or aqueous in-process stream 
shall comply with the provisions of this subpart. The owner or operator 
of an affected facility that does not generate a process wastewater 
stream, maintenance wastewater stream, or aqueous in-process stream is 
exempt from the requirements specified in this subpart, except for the 
requirements specified in Secs. 60.770(a)(2), 60.770(h)(2), 
60.784(d)(12), and 60.785(c)(8) of this subpart.
    (2) If an affected facility begins to or ceases to generate a 
process wastewater stream, maintenance wastewater stream, or aqueous 
in-process stream, the owner or operator shall reevaluate the 
applicability of this subpart to the affected facility. If an affected 
facility is subject to the provisions of this subpart, the owner or 
operator may elect not to reevaluate applicability.
    (3) The affected facility includes the water and wastewater streams 
listed in paragraphs (h)(3)(i) through (h)(3)(vi) of this section, but 
they are not subject to the requirements of this subpart or the 
provisions of subpart A of this part.
    (i) Stormwater managed in segregated sewers.
    (ii) Water from fire-fighting and deluge systems in segregated 
sewers.
    (iii) Spills.
    (iv) Water from safety showers.
    (v) Water from testing of deluge systems.
    (vi) Water from testing of firefighting systems.


Sec. 60.771  Definitions.

    As used in this subpart, all terms not defined here shall have the 
meaning given them in the Act and in subpart A of this part. The

ended valves or lines, valves, connectors, and instrumentation systems. 
A chemical process unit is identified by its primary product.
    Closed biological treatment process means a tank or surface 
impoundment where biological treatment occurs and VOC emissions from 
the treatment process are routed either to a control device by means of 
a closed vent system or to a fuel gas system by means of hard-piping. 
The tank or surface impoundment has a fixed roof, as defined in this 
section, or a floating flexible membrane cover that meets the 
requirements specified in 40 CFR 63.134.
    Closed-vent system means a system that is not open to the 
atmosphere and is composed of hard-piping, ductwork, connections, and, 
if necessary, flow inducing devices that transport gas or vapor from an

    (a) General. The owner or operator shall follow the procedures 
specified in paragraphs (b), (c), (d), (f), (g), (h) and (j) of this 
section to determine whether a designated CPU that is neither a 
flexible operating unit or part of a flexible operating unit has been 
or will be modified. The owner or operator shall follow the procedures 
specified in paragraphs (b), (c), (e), (f), (g), (h) and (j) of this 
section to determine whether a designated CPU that is a flexible 
operating unit or part of a flexible operating unit has been or will be 
modified. The owner or operator shall follow the procedures specified 
in paragraph (k) of this section to determine whether a designated CPU 
has been or will be reconstructed.
    (b) Determining modification Modification determinations are based 
on the designated CPU. To determine whether a modification has occurred 
or will occur, the owner or operator shall follow the procedures in 
either paragraph (b)(1) or (b)(2) of this section.
    (1) Designate the physical or operational change as a modification.
    (2) Determine whether the physical or operational change 
constitutes a modification by evaluating whether VOC emissions from 
process wastewater and aqueous in-process streams increased as a result 
of the physical or operational change. To make this determination, the 
owner or operator shall follow the procedures specified in paragraph 
(d) or (e), and in paragraphs (f), (g), (h) and (j) of this section, as 
appropriate. Physical and operational changes that are not, by 
themselves, considered modifications under this subpart are listed in 
paragraph (c) of this section.
    (c) Physical or operational changes that are not modifications. The 
changes listed in this paragraph (c) shall not, by themselves, be 
considered modifications under this subpart. Section 60.14(e) does not 
apply for the purposes of this subpart.
    (1) Maintenance, repair, and replacement which the Administrator 
determines to be routine for a source category, subject to the 
provisions of Sec. 60.15 of this part. Replacement of spent catalyst 
with like catalyst is not a modification.

    (3) Physical or operational changes that cost less than 12.5 
percent of the original cost of the existing designated CPU as adjusted 
to reflect capital improvements, casualty losses, and defunct 
equipment. Neither account depreciation or deflation is an allowable 
adjustment. The owner or operator shall keep a record or shall provide 
documentation on demand documenting that the cost was less than 12.5 
percent.
    (4) The relocation or change in ownership of an existing facility.
    (d) Determining VOC emissions generated by a designated CPU that is 
neither a flexible operation unit or part of a flexible operation unit. 
For a

[[Page 68009]]

designated CPU that is neither a flexible operation unit or part of a 
flexible operation unit, the owner or operator shall follow the 
procedures specified in paragraphs (d)(1) through (d)(4) of this 
section to determine whether VOC emissions from process wastewater and 
aqueous in-process streams have increased or will increase after a 
physical or operational change has occurred. The owner or operator is 
required to evaluate only those process wastewater and aqueous in-
process streams that are affected (i.e., changed or created) by the 
physical or operational change. For the purposes of this section, 
``affected process wastewater stream'' and ``affected aqueous in-
process stream'' mean process wastewater streams and aqueous in-process 
streams changed or created by a physical or operational change. The 
owner or operator shall keep a record or shall provide documentation on 
demand showing how it was determined that a process wastewater or 
aqueous in-process stream was not affected by a physical or operational 
change. At a minimum this documentation shall document concentration 
and flow rate of affected process wastewater and aqueous in-process 
streams both before and after a physical or operational change.
    (1) Identify the designated CPU. Identify the designated CPU that 
has undergone or will undergo a physical or operational change.
    (2) Determine VOC emissions before a physical or operational 
change. For each affected process wastewater and aqueous in-process 
stream, the owner or operator shall determine VOC emissions before a 
physical or operational change, i.e., baseline emissions, using VOC 
emissions or VOC mass flow rate as a surrogate for VOC emissions. VOC 
emissions and mass flow rate shall be determined as specified in 
paragraph (f) of this section. The baseline VOC emissions or baseline 
VOC mass flow rate for process wastewater and aqueous in-process 
streams shall be summed as specified in paragraph (j) of this section.
    (3) Determine VOC emissions after a physical or operational change. 
For each affected process wastewater or aqueous in-process stream, the 
owner or operator shall determine VOC emissions after a physical or 
operational change, using VOC emissions or VOC mass flow rate as a 
surrogate for VOC emissions. VOC emissions and mass flow rate shall be 
determined as specified in paragraph (f) of this section. The VOC 
emissions or VOC mass flow rate for process wastewater and aqueous in-
process streams shall be summed as specified in paragraph (j) of this 
section.
    (4) Compare the sum of baseline VOC emissions and the sum of VOC 
emissions after a physical or operational change.
    (i) VOC emissions. The owner or operator shall compare the sum of 
baseline VOC emissions to the sum of VOC emissions after the physical 
or operational change. If the sum of VOC emissions from process 
wastewater and aqueous in-process streams after the physical or 
operational change are greater than the sum of baseline VOC emissions 
from process wastewater and aqueous in-process streams, the VOC 
emissions from process wastewater and aqueous in-process streams have 
increased for the designated CPU.
    (ii) VOC mass flow rate as a surrogate for VOC emissions. For 
process wastewater streams, the owner or operator shall compare the sum 
of baseline VOC mass flow rate at the point of determination to the sum 
of VOC mass flow rate at the point of determination after the physical 
or operational change. The owner or operator shall compare the sum of 
baseline VOC mass flow rate for aqueous in-process streams to the sum 
of VOC mass flow rate for aqueous in-process streams after the physical 
or operational change. If the sum of VOC mass flow rate at the point of 
determination after the physical or operational change is greater than 
the sum of baseline VOC mass flow rate at the point of determination, 
the VOC mass flow rate has increased and the VOC emissions have 
increased for the designated CPU. If the sum of VOC mass flow rate for 
aqueous in-process streams after the physical or operational change is 
greater than the sum of baseline VOC mass flow rate of aqueous in-
process streams, the VOC mass flow rate has increased and the VOC 
emissions increased for the designated CPU. Once a determination has 
been made that VOC mass flow rate has increased, either at the point of 
determination or for aqueous in-process streams, the owner or operator 
may elect not to make the other comparison.
    (e) Determining VOC emissions generated by a designated CPU that is 
a flexible operation unit or part of a flexible operation unit. For a 
designated CPU that is a flexible operation unit or part of a flexible 
operation unit, the owner or operator shall follow the procedures 
specified in paragraphs (e)(1) through (e)(5) of this section to 
determine whether VOC emissions from process wastewater and aqueous in-
process streams have increased or will increase after a physical or 
operational change has occurred. The owner or operator is required to 
evaluate only those process wastewater and aqueous in-process streams 
that are affected (i.e., changed or created) by the physical or 
operational change.
    (1) Identify the designated CPU that has undergone or will undergo 
a physical or operational change.
    (2) Select the baseline product. The owner or operator shall select 
a baseline product from those products that the designated CPU is 
capable of producing without a change in physical or operational 
design. The owner or operator shall use best engineering judgement and 
consider the information specified in paragraphs (e)(2)(i)(A) through 
(e)(2)(i)(D) of this section in identifying these products. Products 
the owner or operator shall not consider are specified in paragraphs 
(e)(2)(ii)(A) through (e)(2)(ii)(C) of this section.
    (i) Products that could be produced by the designated CPU.
    (A) Products the designated CPU currently produces.
    (B) Products that the designated CPU has produced in the past, 
provided that a change in physical or operational design has not 
occurred since the product was last produced.
    (C) Products that the designated CPU reasonably can produce without 
having to change the physical or operational design.
    (D) Products that similar designated CPU have produced.
    (ii) Products that could not be produced by the CPU.
    (A) Products that would require a change in the physical or 
operational design of the designated CPU.
    (B) Products which cannot reasonably be produced, including 
products which cannot be reasonably produced in commercially viable 
quantities, products which are not sold in commerce, and products for 
which no commercial market is reasonably foreseeable or for which there 
is no known use in commerce.
    (C) Products for which the designated CPU may have the theoretical 
physical capacity to produce, but for which the owner or operator does 
not have the technical knowledge necessary to produce that product and 
cannot, through exercise of reasonable due diligence, obtain the 
requisite technical knowledge.
    (3) Determine VOC emissions before a physical or operational 
change. For each affected process wastewater and aqueous in-process 
stream, the owner or operator shall determine VOC emissions before a 
physical or operational change, i.e., baseline emissions, using VOC 
emissions or VOC mass flow rate as a surrogate for VOC emissions. VOC 
emissions and mass flow rate shall be

[[Page 68010]]

determined as specified in paragraph (f) of this section. Baseline VOC 
emissions shall be based on production of the baseline product. The VOC 
emissions or VOC mass flow rate for each process wastewater or aqueous 
in-process stream shall be summed as specified in paragraph (j) of this 
section.
    (4) Determine VOC emissions after a physical or operational change. 
For each process wastewater and aqueous in-process stream, the owner or 
operator shall determine the sum of VOC emissions after a physical or 
operational change using VOC emissions or VOC mass flow rate as a 
surrogate for VOC emissions. VOC emissions and mass flow rate shall be 
determined as specified in paragraph (f) of this section. The VOC 
emissions or VOC mass flow rate for each process wastewater or aqueous 
in-process stream shall be summed as specified in paragraph (j) of this 
section. VOC emissions after the physical or operational change shall 
be based on the production of the product or products that are produced 
after the physical or operational change. The owner or operator may 
consider only the new product(s).
    (5) Compare baseline VOC emissions and VOC emissions after a 
physical or operational change.
    (i) VOC emissions. The owner or operator shall compare the sum of 
baseline VOC emissions to the sum of VOC emissions after the physical 
or operational change. If the sum of VOC emissions from process 
wastewater and aqueous in-process streams after the physical or 
operational change are greater than the sum of baseline VOC emissions 
from process wastewater and aqueous in-process streams, the VOC 
emissions from process wastewater and aqueous in-process streams have 
increased for the designated CPU.
    (ii) VOC mass flow rate as a surrogate for VOC emissions. The owner 
or operator shall compare baseline VOC mass flow rate at the point of 
determination to VOC mass flow rate at the point of determination after 
the physical or operational change. The owner or operator shall compare 
baseline VOC mass flow rate for aqueous in-process streams to VOC mass 
flow rate for aqueous in-process streams after the physical or 
operational change. If the VOC mass flow rate at the point of 
determination after the physical or operational change is greater than 
the baseline VOC mass flow rate at the point of determination, the VOC 
mass flow rate has increased and the VOC emissions have increased for 
the designated CPU. If the VOC mass flow rate for aqueous in-process 
streams after the physical or operational change is greater than the 
baseline VOC mass flow rate of aqueous in-process streams, the VOC mass 
flow rate has increased and the VOC emissions have increased for the 
designated CPU. Once a determination has been made that VOC mass flow 
rate has increased, either at the point of determination or for aqueous 
in-process streams, the owner or operator may elect not to make the 
other comparison.
    (f) Determining VOC emissions. VOC emissions shall be determined 
using either VOC emissions or mass flow rate as a surrogate for VOC 
emissions. VOC emissions and mass flow rate shall be determined on an 
annual average basis. To determine VOC emissions using the default 
fraction emitted value, Fe, for the individual drain system and the 
treatment process, the owner or operator shall use the procedures 
specified in paragraph (f)(1) of this section. To determine VOC 
emissions using site-specific modeling for the individual drain system 
and either the default Fe values for the treatment process or VOC 
emissions for the treatment process, the owner or operator shall use 
the procedures specified in paragraph (f)(2) of this section. To 
determine VOC emissions using annual average mass flow rate as a 
surrogate for emissions, the owner or operator shall follow the 
procedures specified in paragraph (f)(3) of this section.
    (1) Calculate VOC emissions using the default fraction emitted 
value, Fe, for the individual drain system and the treatment process. 
For each process wastewater stream and aqueous in-process stream, the 
owner or operator shall calculate VOC emissions using the default Fe 
values for the individual drain system and the treatment process and 
use equation 1 in this paragraph (f)(1). The default Fe values for the 
individual drain system and the treatment process are listed in table 2 
in appendix J of this part. Annual average concentration shall be 
determined using the procedures specified in paragraph (g)(1) of this 
section. Annual average flow rate shall be determined using the 
procedures specified in paragraph (h) of this section. The owner or 
operator is not required to determine the concentration of VOC that are 
not reasonably expected to be in the process. The owner or operator is 
required to consider only VOC included on the stream-specific list of 
VOC when measuring VOC concentrations. The stream-specific list of VOC 
shall be as determined as specified in Sec. 60.778 of this subpart.

concentration shall be a flow-weighted average representative of actual 
or anticipated operation of the designated CPU generating the process 
wastewater or aqueous in-process stream generated by the designated CPU 
over the designated 12-month period. Flow-weighted annual average

occurring in the process wastewater stream or aqueous in-process stream 
during the designated 12-month period divided by the total mass of the 
process wastewater stream or aqueous in-process stream during the same 
designated 12-month period. The owner or operator shall determine the 
annual average concentration using the procedures specified in 
paragraphs (g)(1)(i) through (g)(1)(iv) of this section. The owner or 
operator is required to consider only VOC included on the stream-
specific list of VOC when measuring VOC concentrations. The stream-
specific list of VOC shall be as determined as specified in Sec. 60.778 
of this subpart.
    (1) VOC emissions. When an owner or operator is determining 
concentration as part of determining annual average VOC emissions under 
paragraph (f)(1) or paragraph (f)(2) of this section, the procedures in 
paragraphs (g)(1)(i) through (g)(1)(iv) of this section shall be used.
    (i) For process wastewater streams, the annual average 
concentration shall be determined either at the point of determination 
or downstream of the point of determination, with adjustment for 
concentration changes made according to Sec. 60.782(b)(6) of this 
subpart if a point downstream of the point of determination is used.

wastewater stream or aqueous in-process stream shall be taken. Samples 
may be grab samples or composite samples.
    (iv) Concentration values that are not determined using Method 25D 
may be adjusted with the chemical's Fm value. Chemical-specific Fm 
factors shall be determined as specified in appendix J of this part. 
When Fm adjustments are made, they shall be used for all compounds and 
in all instances for the purpose of this section.
    (2) VOC mass flow rate. When an owner or operator is determining 
concentration as part of determining annual average VOC mass flow rate 
under paragraph (f)(3) of this section, the procedures specified in 
paragraph (g)(2)(i) and (g)(2)(ii) of this section shall be used. 
Measurements shall be taken at the point of determination.
    (i) If an owner or operator is measuring concentration as part of 
determining annual average VOC mass flow rate under paragraph (f)(3) of 
this section, Method 25D of 40 CFR part 60, appendix A shall be used to 
determine annual average concentration.
    (ii) A minimum of three wastewater samples from each process 
wastewater stream or aqueous in-process stream shall be taken. Samples 
may be grab samples or composite samples.
    (h) Determining annual average flow rate for a process wastewater 
stream or aqueous in-process stream. The annual average flow rate shall 
be representative of the process wastewater stream or aqueous in-
process stream generated by the designated CPU over the designated 12-
month period. The owner or operator shall consider the total annual 
average wastewater volume generated by the designated CPU. The owner or 
operator shall determine the annual average flow rate using the 
procedures specified in paragraphs (h)(1) and (h)(2) of this section.
    (1) For process wastewater streams, the annual average flow rate 
shall be determined either at the point of determination or downstream 
of the point of determination, with adjustment for flow rate changes 
made according to Sec. 60.782(c)(4) of this subpart if a point 
downstream of the point of determination is used. For aqueous in-
process streams, the annual average flow rate shall be determined 
before the point of determination, and the owner or operator shall make 
corrections if streams are mixed or treated before being measured.
    (2) The procedures in Sec. 60.782(c)(1) through (c)(3) of this 
subpart are considered acceptable procedures for determining flow rate. 
The procedures in Sec. 60.782(c)(1) through (c)(3) of this subpart may 
be used in combination, and no one procedure shall take precedence over 
another.

Sum the annual average VOC mass flow rate, as calculated in paragraph 
(f)(3) of this section, for each aqueous in-process stream affected by 
the physical or operational change to determine the annual average VOC 
mass flow rate for the designated CPU. Once a determination has been 
made that VOC emissions have increased, the owner or operator can elect 
not to make the other comparison.
    (k) Reconstruction. (1) For the purposes of this subpart ``fixed 
capital cost of the new components,'' as used in Sec. 60.15 of this 
part, includes the fixed capital cost of all depreciable components 
which are replaced within any 2-year rolling period following September 
12, 1994. Replacement costs shall be charged to the first day the owner 
or operator incurred any expenses involving the actual work of 
replacement, i.e., the designated CPU has had either components removed 
in preparation of the replacements or components added as replacements. 
When replacement of components, e.g., replacing a distillation column, 
is reasonably viewed as a project, the cost of the entire project shall 
be charged to the first day the owner or operator incurred any expenses 
involving the actual work of replacement.
    (2) The owner or operator shall either keep a record for the 
purposes of this subpart or provide on demand documentation kept for 
financial or tax purposes that documents when costs for replacements 
were first incurred and the costs of the replacements.

    (ii) The annual average concentration of VOC is greater than or 
equal to 500 parts per million by weight and the annual average flow 
rate is greater than or equal to 1 liter per minute.
    (2) A wastewater stream is a Group 2 wastewater stream if it is not 
a Group 1 wastewater stream by the criteria in paragraph (b)(1) of this 
section.
    (c) How to designate a Group 1 wastewater stream. The owner or 
operator may elect to designate a wastewater stream as a Group 1

streams as a Group 1 wastewater stream, the procedures specified in 
paragraphs (c)(1) and (c)(2) of this section and Sec. 60.782(a)(2) of 
this subpart shall be followed.
    (1) From the point of determination for each wastewater stream that 
is included in the Group 1 designation to the location where the owner 
or operator elects to designate such wastewater stream(s) as a Group 1 
wastewater stream, the owner or operator shall comply with all 
applicable emission suppression requirements specified in Sec. 60.774 
of this subpart.

specified in Sec. 60.774 of this subpart and with the treatment 
requirements in Sec. 60.779 of this subpart.
    (d) Owners or operators shall not discard liquid or solid organic 
materials containing greater than 10,000 parts per million VOC (as 
determined by analysis of the stream composition, engineering 
calculations, or process knowledge) from a chemical process unit to 
water or wastewater, unless the receiving stream is managed and treated 
as a Group 1 wastewater stream. This prohibition does not apply to 
materials from the activities listed in paragraphs (d)(1) through 
(d)(4) of this section.
    (1) Equipment leaks;
    (2) Activities included in maintenance or startup/shutdown/
malfunction plans;

     (4) Samples.
    (e) Off-site or third-party treatment. The owner or operator may 
elect to transfer a Group 1 wastewater stream or residual removed from 
a Group 1 wastewater stream to an on-site treatment operation not owned 
or operated by the owner or operator of the affected facility 
generating the wastewater stream or residual, or to an off-site 
treatment operation.
    (1) The owner or operator transferring the wastewater stream or 
residual shall:
    (i) Comply with the provisions specified in Sec. 60.774 of this 
subpart for each waste management unit that receives or manages a Group 
1 wastewater stream or residual removed from a Group 1 wastewater 
stream prior to shipment or transport.
    (ii) Include a notice with the shipment or transport of each Group 
1 wastewater stream or residual removed from a Group 1 wastewater 
stream. The notice shall state that the wastewater stream or residual 
contains VOC that are to be treated in accordance with the provisions 
of this subpart. When the transport is continuous or ongoing (for 
example, discharge to a publicly-owned treatment works), the notice 
shall be submitted to the treatment operator initially and whenever 
there is a change in the required treatment. These notices shall be 
retained by the owner or operator as specified in Sec. 60.785(c) of 
this subpart.
    (2) The owner or operator may not transfer the wastewater stream or 
residual unless the transferee has submitted to EPA a written 
certification that the transferee will manage and treat any Group 1 
wastewater stream or residual removed from a Group 1 wastewater stream 
received from a affected facility subject to the requirements of this 
subpart in accordance with the requirements of either Secs. 60.774 
through 60.786 of this subpart or Sec. 60.787(b) of this subpart if 
alternative emission limitations have been granted the transferor in 
accordance with those provisions. The certifying entity may revoke the 
written certification by sending a written statement to EPA and the 
owner or operator giving at least 90 days notice that the certifying 
entity is rescinding acceptance of responsibility for compliance with 
the regulatory provisions listed in this paragraph (e)(2). Upon 
expiration of the notice period, the owner or operator may not transfer 
the wastewater stream or residual to the treatment operation.

[[Page 68014]]

    (3) By providing this written certification to EPA the certifying 
entity accepts responsibility for compliance with the regulatory 
provisions listed in paragraph (e)(2) of this section with respect to 
any shipment of wastewater or residual covered by the written 
certification. Failure to abide by any of those provisions with respect 
to such shipments may result in enforcement action by EPA against the 
certifying entity in accordance with the enforcement provisions 
applicable to violations of these provisions by owners or operators of 
affected facilities.
    (4) Written certifications and revocation statements, to EPA from 
the transferees of wastewater or residuals shall be signed by a 
responsible official of the certifying entity, provide the name and 
address of the certifying entity, and be sent to the appropriate EPA 
Regional Office. Such written certifications are not transferable by 
the treater.

    (a) Each owner or operator of an affected facility subject to this 
subpart shall comply with the requirements of paragraphs (b) through 
(e) of this section for maintenance wastewaters containing VOC.
    (b) The owner or operator shall prepare a description of 
maintenance procedures for management of maintenance wastewaters 
generated from the emptying and purging of equipment in the process 
during temporary shutdowns for inspections, maintenance, and repair 
(i.e., a maintenance-turnaround) and during periods which are not 
shutdowns (i.e., routine maintenance). The descriptions shall be as 
follows:
    (1) Specify the process equipment or maintenance tasks that are 
anticipated to create wastewater during maintenance activities.
    (2) Specify the procedures that will be followed to properly manage 
the wastewater and control VOC emissions to the atmosphere; and
    (3) Specify the procedures to be followed when clearing materials 
from process equipment.
    (c) The owner or operator shall modify and update the information 
required by paragraph (b) of this section as needed to reflect new or 
revised equipment or procedures.
    (d) The owner or operator shall implement the procedures described 
in paragraphs (b) and (c) of this section as part of the start-up, 
shutdown, and malfunction plan required in Sec. 60.787 of this subpart.
    (e) The owner or operator shall maintain a record of the 
information required by paragraphs (b) and (c) of this section as part 
of the start-up, shutdown, and malfunction plan required in Sec. 60.787 
of this subpart.


Sec. 60.777  Delay of repair.

    (a) Delay of repair of equipment for which a control equipment 
failure or a gap, crack, tear, or hole has been identified, is allowed 
if the repair is technically infeasible without a shutdown, as defined 
in Sec. 60.771 of this subpart, or if the owner or operator determines 
that VOC emissions of purged material from immediate repair would be 
greater than the VOC emissions likely to result from delay of repair. 
Repair of this equipment shall occur by the end of the next shutdown.
    (b) Delay of repair of equipment for which a control equipment 
failure or a gap, crack, tear, or hole has been identified, is allowed 
if the equipment is emptied or is no longer used to treat or manage 
Group 1 wastewater streams or residuals removed from Group 1 wastewater 
streams.
    (c) Delay of repair of equipment for which a control equipment 
failure or a gap, crack, tear, or hole has been identified is also 
allowed if additional time is necessary due to the unavailability of 
parts beyond the control of the owner or operator. Repair shall be 
completed as soon as practical. The owner or operator who uses this 
provision shall comply with the requirements of Sec. 60.785(b)(7) of 
this subpart to document the reasons that the delay of repair was 
necessary.


Sec. 60.778  Stream-specific list of VOC determination.

    (a) General. This section specifies how to determine a stream-
specific list of VOC for a process wastewater stream or in-process 
aqueous stream. A stream-specific list of VOC is required when 
speciation is used for compliance demonstration (i.e., performance 
tests, design evaluations, and ranges of parameters set for monitoring 
and for determining if VOC emissions increase has occurred for 
modification determinations. A stream-specific list may also be used 
for Group 1 and Group 2 determinations.
    (b) Test methods for determining VOC concentration. The owner or 
operator shall use one of the test methods that speciates compounds and 
is specified in Sec. 60.782(b)(5) of this subpart to determine 
concentration. For process wastewater streams, the annual average 
concentration shall be determined either

[[Page 68024]]

at the point of determination or downstream of the point of 
determination, with adjustment for concentration changes made according 
to Sec. 60.782(b)(6) of this subpart if a point downstream of the point 
of determination is used. For aqueous in-process streams, the annual 
average concentration shall be determined before the point of 
determination and shall be adjusted for any losses of VOC to the 
atmosphere and for dilution.
    (c) Compounds that may be excluded from the site-specific list of 
VOC. Compounds that meet the requirements specified in paragraphs 
(b)(1), (b)(2), or (b)(3) of this section are not required to be 
included in the stream-specific list of VOC. The owner or operator 
shall use one of the methods specified in Sec. 60.782(b)(5) of this 
subpart to determine concentration.
    (1) Compounds not used or produced by the chemical process unit.
    (2) Compounds with concentrations at the point of determination 
that are below 1 part per million by weight.
    (3) Compounds with concentrations at the point of determination 
that are below the lower detection limit where the lower detection 
limit is greater than 1 part per million by weight. The method used for 
determining concentration shall be an analytical method for wastewater 
which has the compound of interest as a target analyte.
    (d) Create stream-specific list of VOC for Group 1 and Group 2 
determination. The owner or operator shall include those individual VOC 
with the greatest mass on the stream-specific list of VOC until 75 
compounds or every compound, whichever is fewer, is included on the 
list, except as provided by paragraph (c) of this section. The stream-
specific list of VOC must represent at least 90 percent of the total 
VOC in the process wastewater stream. If the compounds on the stream-
specific list of VOC do not represent at least 90 percent of total VOC, 
Method 25D to appendix A of this part shall be used to make the Group 1 
determination for that process wastewater stream. The owner or operator 
shall document how the percent of VOC in the process wastewater stream 
was determined.
    (e) Create stream-specific list of VOC for estimating VOC emission 
changes for modification determinations. The owner or operator shall 
include those individual VOC with the greatest mass on the stream-
specific list of VOC until 75 compounds or every compound, whichever is 
fewer, is included on the list, except as provided by paragraph (c) of 
this section. The stream-specific list of VOC must represent at least 
90 percent of the total VOC in the process wastewater stream or aqueous 
in-process stream. If the compounds on the stream-specific list of VOC 
do not represent at least 90 percent of total VOC, the owner or 
operator shall use the mass flow rate procedure specified in 
Sec. 60.772 of this subpart to estimate VOC emissions for modification 
determinations. The owner or operator shall document how the percent of 
VOC in the process wastewater stream or aqueous in-process stream was 
determined.
    (f) Create stream-specific list of VOC for compliance 
demonstrations. The owner or operator shall determine the percent of 
total VOC in the process wastewater stream. The owner or operator shall 
document how the percent of VOC in the process wastewater stream was 
determined.
    (i) For the owner or operator that can identify at least 90 
percent, by mass, of the VOC in the wastewater stream or aqueous in-
process stream, the individual VOC that are 5 percent, by mass, or 
greater, are required to be included on the list. If less than half of 
the total VOC in the wastewater are represented by the compounds with a 
mass of 5 percent or greater, the owner or operator shall include those 
individual VOC with the greatest mass on the stream-specific list of 
VOC until 75 compounds or every compound, whichever is fewer, is 
included on the list, except as provided by paragraph (c) of this 
section. The owner or operator shall document that the site-specific 
list of VOC is representative of the process wastewater stream and 
forms the basis of a good compliance demonstration.
    (ii) For the owner or operator that can identify at least 50 
percent, by mass, of the VOC in the wastewater stream, the individual 
VOC with the greatest mass on the stream-specific list of VOC up to 75 
compounds or every compound, whichever is fewer, are to be included on 
the list, except as provided by paragraph (c) of this section. The 
owner or operator shall document that the site-specific list of VOC is 
representative of the process wastewater stream and forms the basis of 
a good compliance demonstration.
    (iii) For the owner or operator that cannot identify at least 50 
percent, by mass, of the VOC in the process wastewater stream, one of 
the following compliance options shall be used to treat the process 
wastewater stream:
    (A) The design steam stripper option in Sec. 60.779(d) of this 
subpart; or
    (B) The 95 percent mass removal with outlet concentration of 50 
ppmw option in Sec. 60.779(e)(2) of this subpart; or
    (C) The steam stripper option in Sec. 60.779(e)(3) of this subpart.


Sec. 60.779  Process wastewater provisions--Performance standards for 
treatment processes managing Group 1 wastewater streams and/or 
residuals removed from Group 1 wastewater streams.

    (a) This section specifies the performance standards for treating 
process wastewater streams that are Group 1 wastewater streams. The 
owner or operator shall comply with the requirements as specified in 
paragraphs (a)(1) through (a)(8) of this section. Where multiple 
compliance options are provided, the options may be used in combination 
for different wastewater streams and/or for different compounds in the 
same wastewater streams, except where otherwise provided in this 
section. Once a Group 1 wastewater stream or residual removed from a 
Group 1 wastewater stream has been treated in accordance with this 
subpart, it is no longer subject to the requirements of this subpart.
    (1) Control options: Group 1 wastewater streams. The owner or 
operator shall comply with the requirements specified in any one of 
paragraphs (d), (e), (f), (g), (h), or (m) of this section, except as 
provided in Sec. 60.789 of this subpart for relationship with other 
rules.
    (2) [Reserved]
    (3) Biological treatment processes. Biological treatment processes 
in compliance with this section may be either open or closed biological 
treatment processes as defined in Sec. 60.771 of this subpart. An open 
biological treatment process in compliance with this section need not 
be covered and vented to a control device as required in Sec. 60.774 of 
this subpart. An open or a closed biological treatment process in 
compliance with this section and using Secs. 60.783(f) or 60.783(g) of 
this subpart to demonstrate compliance is not subject to the 
requirements of Sec. 60.774 of this subpart. A closed biological 
treatment process in compliance with this section and using 
Sec. 60.783(e) of this subpart to demonstrate compliance shall comply 
with the requirements of Sec. 60.774 of this subpart. Waste management 
units upstream of an open or closed biological treatment process shall 
meet the requirements of Sec. 60.774 of this subpart, as applicable.
    (4) Performance tests and design evaluations.  If the design steam 
stripper option (paragraph (d) of this section) or the Resource 
Conservation and Recovery Act (RCRA) option (paragraph (h) of this 
section) is selected to comply with this section, neither a design 
evaluation nor a performance test is required. If Sec. 60.789(d) of 
this subpart (Relationship to the HON) is selected to

[[Page 68025]]

comply with this section, the performance test or design evaluation 
used to demonstrate compliance for the HON also demonstrates compliance 
with this section. For any other non-biological treatment process, and 
for closed biological treatment processes as defined in Sec. 60.771 of 
this subpart, the owner or operator shall conduct either a design 
evaluation as specified in paragraph (j) of this section, or a 
performance test as specified in Sec. 60.783 of this subpart. For each 
open biological treatment process as defined in Sec. 60.771 of this 
subpart, the owner or operator shall conduct a performance test as 
specified in Sec. 60.783 of this subpart.

    Note to paragraph (a)(4) of this section: Some open biological 
treatment processes may not require a performance test. Refer to 
Sec. 60.783(h) of this subpart and table 36 of the appendix to 
subpart G of 40 CFR part 63 to determine whether the biological 
treatment process meets the criteria that exempt the owner or 
operator from conducting a performance test.)

    (5) Control device requirements. When gases are vented from the 
treatment process, the owner or operator shall comply with the 
applicable control device requirements specified in Secs. 60.780 and 
60.783(i) and (j) of this subpart, and the applicable leak inspection 
provisions specified in Sec. 60.786 of this subpart. This requirement 
does not apply to any open biological treatment process that meets the 
mass removal requirements. Vents from anaerobic biological treatment 
processes may be routed through hard-piping to a fuel gas system.
    (6) Residuals: general. When residuals result from treating Group 1 
wastewater streams, the owner or operator shall comply with the 
requirements for residuals specified in paragraph (k) of this section.
    (7) Treatment using a series of treatment processes. In all cases 
where the wastewater provisions in this subpart allow or require the 
use of a treatment process or control device to comply with emissions 
limitations, the owner or operator may use multiple treatment processes 
or control devices, respectively. For combinations of treatment 
processes where the wastewater stream is conveyed by hard-piping, the 
owner or operator shall comply with either the requirements of 
paragraph (a)(7)(i) or (a)(7)(ii) of this section. For combinations of 
treatment processes where the wastewater stream is not conveyed by 
hard-piping, the owner or operator shall comply with the requirements 
of paragraph (a)(7)(ii) of this section. For combinations of control 
devices, the owner or operator shall comply with the requirements of 
paragraph (a)(7)(i) of this section.
    (i)(A) For combinations of treatment processes, the wastewater 
stream shall be conveyed by hard-piping between the treatment 
processes. For combinations of control devices, the vented gas stream 
shall be conveyed by hard-piping between the control devices.
    (B) For combinations of treatment processes, each treatment process 
shall meet the applicable requirements of Sec. 60.774 of this subpart 
except as provided in paragraph (a)(3) of this section.
    (C) The owner or operator shall identify, and keep a record of, the 
combination of treatment processes or of control devices, including 
identification of the first and last treatment process or control 
device.
    (D) The performance test or design evaluation shall determine 
compliance across the combination of treatment processes or control 
devices. If a performance test is conducted, the ``inlet'' shall be the 
point at which the wastewater stream or residual enters the first 
treatment process, or the vented gas stream enters the first control 
device. The ``outlet'' shall be the point at which the treated 
wastewater stream exits the last treatment process, or the vented gas 
stream exits the last control device.
    (ii)(A) For combinations of treatment processes, each treatment 
process shall meet the applicable requirements of Sec. 60.774 of this 
subpart except as provided in paragraph (a)(3) of this section.
    (B) The owner or operator shall identify, and keep a record of, the 
combination of treatment processes, including identification of the 
first and last treatment process.
    (C) The owner or operator shall determine the mass removed or 
destroyed by each treatment process. The performance test or design 
evaluation shall determine compliance for the combination of treatment 
processes by adding together the mass removed or destroyed by each 
treatment process.
    (8) Prohibition against double counting. The removal of VOC must be 
in addition to the reduction and destruction required by other rules, 
unless the removal of VOC is from the same stream.
    (b) [Reserved]
    (c) [Reserved]
    (d) Design steam stripper option. The owner or operator shall 
operate and maintain a steam stripper that meets the requirements of 
paragraphs (d)(1) through (d)(6) of this section.

    (2) Countercurrent flow configuration with a minimum of 10 actual 
trays;
    (3) Minimum steam flow rate of 0.04 kilograms of steam per liter of 
wastewater feed within the column;
    (4) Minimum wastewater feed temperature to the steam stripper of 
95 deg. C, or minimum column operating temperature of 95 deg. C;
    (5) Maximum liquid loading of 67,100 liters per hour per square 
meter; and
    (6) Operate at nominal atmospheric pressure.
    (e) Percent mass removal/destruction option, for nonbiological 
treatment process. For wastewater streams that are Group 1 and treated 
in a nonbiological treatment process, the owner or operator shall 
comply with either paragraph (e)(1) or (e)(2) of this section for a 
noncombustion treatment process and paragraph (e)(1) of this section 
for a combustion treatment process. For wastewater streams that are 
Group 1 and treated in a steam stripper, the owner or operator shall 
comply with either paragraph (e)(1), (e)(2), or (e)(3) of this section. 
This paragraph (e) shall not be used for biological treatment 
processes.
    (1) Reduce mass flow rate of VOC by the appropriate Fr values. For 
wastewater streams that are Group 1, the owner or operator shall 
reduce, by removal or destruction, the mass flow rate of VOC by the 
required removal or destruction efficiency, i.e., the flow-weighted 
average Fr value. To use this compliance option, the owner or operator 
shall develop a stream-specific list of VOC upon which to base the 
compliance demonstration and shall calculate a flow-weighted average 
Fr. Follow the procedures in Sec. 60.778 of this subpart to develop a 
stream-specific list of VOC. Follow the procedures in appendix J of 
this part to determine Fr values for individual compounds. The owner or 
operator shall conduct either a design evaluation or a performance 
test. Design evaluation requirements are specified in paragraph (j) of 
this section. Performance test requirements are specified in 
Sec. 60.783(c) of this subpart, for noncombustion treatment processes, 
and in Sec. 60.783(d) of this subpart, for combustion treatment 
processes.
    (2) Reduce mass flow rate of VOC by 95 percent and reduce outlet 
concentration of VOC to less than 50 ppmw, for noncombustion treatment 
process. For wastewater streams that are Group 1, the owner or operator 
shall reduce, by removal or destruction, the mass flow rate of VOC by 
95 percent and reduce the outlet concentration of VOC to less than 50 
ppmw. The owner or operator shall conduct either a design evaluation or 
a performance test. Design evaluation requirements are specified in

[[Page 68026]]

paragraph (j) of this section. Performance test requirements are 
specified in Sec. 60.783(c) of this subpart.
    (3) Demonstrate a steam stripper reduces mass flow rate of 
methanol, ethylene glycol monobutyl ether acetate, and methyl ethyl 
ketone by the appropriate Fr value. For wastewater steams that are 
Group 1 and treated in a steam stripper, the owner or operator shall 
demonstrate that the mass flow rate of methanol is reduced by 31 
percent; that the mass flow rate of ethylene glycol monobutyl ether 
acetate is reduced by 76 percent; and that the mass flow rate of methyl 
ethyl ketone is reduced by 95 percent. The owner or operator shall 
conduct either a design evaluation or a performance test. Design 
evaluation requirements are specified in paragraph (j) of this section. 
Performance test requirements are specified in Sec. 60.783(c) of this 
subpart. When design evaluations are used to demonstrate compliance, 
the Henry's law constant at 25 deg. C (expressed as y/x atmosphere per 
mole fraction) used in the evaluation shall be: 7.73 for methanol; 
24.96 for ethylene glycol monobutyl ether acetate; and 59.2 for methyl 
ethyl ketone.
    (f) Required mass removal (RMR) option, for noncombustion treatment 
process. For wastewater streams that are Group 1, the owner or operator 
shall reduce, by removal or destruction, the mass flow rate of VOC by 
the required mass removal, i.e, the flow-weighted average Fr. To use 
this compliance option, the owner or operator shall develop a list of 
VOC upon which to base the compliance demonstration and shall calculate 
a flow-weighted average Fr. Follow the procedures in Sec. 60.778 of 
this subpart to develop a stream-specific list of VOC. Follow the 
procedures in appendix J of this part to determine Fr values. The owner 
or operator shall conduct a compliance demonstration as specified in 
paragraphs (f)(1), (f)(2), and (f)(3) of this section.
    (1) Nonbiological, noncombustion treatment process. The owner or 
operator shall conduct either a design evaluation or a performance 
test. Design evaluation requirements are specified in paragraph (j) of 
this section. Performance test requirements are specified in 
Sec. 60.783(e) of this subpart.
    (2) Aerobic biological treatment process--open and closed 
biological treatment processes. Closed biological treatment process 
means a tank or surface impoundment where biological treatment occurs 
and air VOC emissions from the treatment process are routed to either a 
control device by means of a closed vent system or to a fuel gas system 
by means of hard-piping. The tank or surface impoundment has a fixed 
roof, as defined in Sec. 60.771 of this subpart, or a floating flexible 
membrane cover that meets the requirements specified in 40 CFR 
Sec. 63.134. Open biological treatment process is not a closed 
biological treatment process. Open biological treatment processes have 
additional requirements for compliance demonstration because they have 
more potential for VOC emissions.
    (i) Closed biological treatment process. The owner or operator 
shall conduct either a design evaluation or a performance test. Design 
evaluation requirements are specified in paragraph (j) of this section. 
Performance test requirements are specified in both Sec. 60.783(e) or 
(f) of this subpart.
    (ii) Open biological treatment process. The owner or operator shall 
conduct a performance test as specified in Sec. 60.783(f) of this 
subpart, except as provided in Sec. 60.783(h) of this subpart.

treatment process shall also be a closed biological treatment process. 
The owner or operator shall conduct either a design evaluation or a 
performance test. Design evaluation requirements are specified in 
paragraph (j) of this section. Performance test requirements are 
specified in Sec. 60.783(e) of this subpart.
    (g) 95-percent RMR option, for biological treatment processes. The 
owner or operator shall reduce, by removal or destruction, the mass 
flow rate of VOC by 95 percent for all wastewater entering the 
biological treatment process. To use this compliance option, the owner 
or operator shall develop a stream-specific list of VOC as specified in 
Sec. 60.778 of this subpart upon which to base the compliance 
demonstration. The owner or operator shall conduct a compliance 
demonstration as specified in paragraphs (g)(1) and (g)(2) of this 
section. The owner or operator shall also comply with paragraphs (g)(3) 
and (g)(4) of this section.
    (1) Aerobic biological treatment process--open and closed 
biological treatment processes.

shall conduct either a design evaluation or a performance test. Design 
evaluation requirements are specified in paragraph (j) of this section. 
Performance test requirements are specified in both Sec. 60.783(e) and 
(g) of this subpart.
    (ii) Open biological treatment process. The owner or operator shall 
conduct a performance test as specified in Sec. 60.783(g) of this 
subpart, except as provided in Sec. 60.783(h) of this subpart.
    (2) Anaerobic biological treatment process. An anaerobic biological 
treatment process shall also be a closed biological treatment process. 
The owner or operator shall conduct either a design evaluation or a 
performance test. Design evaluation requirements are specified in 
paragraph (j) of this section. Performance test requirements are 
specified in Sec. 60.783(e) of this subpart.
    (3) For each treatment process or waste management unit that 
receives, manages, or treats wastewater streams subject to this 
paragraph (g)(3), from the point of determination of each Group 1 or 
Group 2 wastewater stream to the biological treatment unit, the owner 
or operator shall comply with Sec. 60.774 of this subpart for control 
of air VOC emissions.
    (4) If a wastewater stream is in compliance with the requirements 
in paragraph (d), (e), (f), (h), or (m) of this section before entering 
the biological treatment unit, the VOC mass of that wastewater is not 
required to be included in the total mass flow rate entering the 
biological treatment unit for the purpose of demonstrating compliance.
    (h) Treatment in a RCRA unit option. The owner or operator shall 
treat the wastewater stream or residual in a unit identified in, and 
complying with, paragraphs (h)(1), (h)(2), or (h)(3) of this section. 
These units are exempt from the design evaluation or performance tests 
requirements specified in paragraphs (a)(4) and (j) of this section, 
and from the monitoring requirements specified in Sec. 60.781 of this 
subpart, as well as recordkeeping and reporting requirements associated 
with monitoring and performance tests.
    (1) The wastewater stream or residual is discharged to a hazardous 
waste incinerator for which the owner or operator has been issued a 
final permit under 40 CFR part 270 and complies with the requirements 
of 40 CFR part 264, subpart O, or has certified compliance with the 
interim status requirements of 40 CFR part 265, subpart O;
    (2) The wastewater stream or residual is discharged to a process 
heater or boiler burning hazardous waste for which the owner or

    (ii) Has certified compliance with the interim status requirements 
of 40 CFR part 266, subpart H.
    (3) The wastewater stream or residual is discharged to an 
underground injection well for which the owner or operator has been 
issued a final permit

[[Page 68027]]

under 40 CFR part 270 or 40 CFR part 144 and complies with the 
requirements of 40 CFR part 122. The owner or operator shall comply 
with all applicable requirements of this subpart prior to the point 
where the wastewater enters the underground portion of the injection 
well.
    (i) [Reserved]
    (j) Design evaluations or performance tests for treatment 
processes. Except as provided in paragraph (j)(3), (h), or (m) of this 
section, the owner or operator shall demonstrate by the procedures in 
either paragraph (j)(1) or (j)(2) of this section that each 
nonbiological treatment process used to comply with paragraphs (e), 
and/or (f) of this section achieves the conditions specified for 
compliance. The owner or operator shall demonstrate by the procedures 
in either paragraph (j)(1) or (j)(2) of this section that each closed 
biological treatment process used to comply with paragraphs (f) or (g) 
of this section achieves the conditions specified for compliance. If an 
open biological treatment unit is used to comply with paragraph (f) or 
(g) of this section, the owner or operator shall comply with 
Sec. 60.783(f) or Sec. 60.783(g), respectively, of this subpart. Some 
open biological treatment processes may not require a performance test. 
Refer to Sec. 60.783(h) of this subpart to determine whether the open 
biological treatment process meets the criteria that exempt the owner 
or operator from conducting a performance test.
    (1) This paragraph (j)(1) may be used to demonstrate compliance 
with paragraphs (e), (f), or (g) of this section, except when the 
treatment process is an open biological treatment process. A design 
evaluation and supporting documentation that addresses the operating 
characteristics of the treatment process and that is based on operation 
at a representative wastewater stream flow rate and a representative 
concentration under which it would be most difficult to demonstrate 
compliance. For closed biological treatment processes, the actual mass 
removal shall be determined by a mass balance over the unit. The mass 
flow rate of VOC exiting the treatment process shall be the sum of the 
mass flow rate of VOC in the wastewater stream exiting the biological 
treatment process and the mass flow rate of the vented gas stream 
exiting the control device. The mass flow rate entering the treatment 
process minus the mass flow rate exiting the process determines the 
actual mass removal.
    (2) This paragraph (j)(2) may be used to demonstrate compliance 
with paragraphs (e), (f), or (g) of this section. Performance tests 
conducted using test methods and procedures that meet the applicable 
requirements specified in Sec. 60.783 of this subpart.
    (3) The provisions of paragraphs (j)(1) and (j)(2) of this section 
do not apply to design stream strippers which meet the requirements of 
paragraph (d) of this section.
    (k) Residuals. For each residual removed from a Group 1 wastewater 
stream, the owner or operator shall control for air VOC emissions by 
complying with Sec. 60.774 of this subpart and by complying with one of 
the provisions in paragraphs (k)(1) through (k)(4) of this section.
    (1) Recycle the residual to a production process or sell the 
residual for the purpose of recycling. Once a residual is returned to a 
production process, the residual is no longer subject to this section.
    (2) Return the residual to the treatment process.
    (3) Treat the residual to destroy the total combined mass flow rate 
of VOC by 99 percent or more, as determined by the procedures specified 
in Sec. 60.783(c) or (d) of this subpart.
    (4) Comply with the requirements for RCRA treatment options 
specified in paragraph (h) of this section.
    (l) [Reserved]
    (m) 1 Mg exemption. For each plant site, up to 1 Mg of VOC per year 
may be excluded from control. The 1 Mg shall be based on an annual 
average and calculated according to procedures in paragraphs (m)(1) and 
(m)(2) of this section.
    (1) Annual average concentration. The annual average concentration 
shall be a flow-weighted average representative of actual or 
anticipated operation of the CPU generating the process wastewater over 
a designated 12-month period. For flexible operation units, the owner 
or operator shall consider the anticipated production over the 
designated 12-month period and include all process wastewater streams 
generated by the process equipment during this period. The owner or 
operator is not required to determine the concentration of VOC that are 
not reasonably expected to be in the process. Concentration values that 
are not determined using Method 25D may be adjusted with the chemical's 
Fm value. Compound-specific Fm factors shall be determined as specified 
in appendix J of this part. Flow-weighted annual average concentrations 
for VOC means the total mass of VOC occurring in the wastewater stream 
during the designated 12-month period divided by the total mass of the 
wastewater stream during the same designated 12-month period. The 
annual average concentration shall be determined for each process 
wastewater stream either at the point of determination, or downstream 
of the point of determination with adjustment for concentration changes 
made according to Sec. 60.782 of this subpart. The procedures specified 
in Sec. 60.782(b)(5)(i) through (b)(5)(iv) and (b)(6) of this subpart 
are considered acceptable for determining the annual average 
concentration. They may be used in combination, and no one procedure 
shall take precedence over another. A minimum of three wastewater 
samples from each process wastewater stream shall be taken. Samples may 
be grab samples or composite samples.
    (2) Annual average flow rate. The owner or operator shall determine 
the annual average flow rate by measuring flow rate either at the point 
of determination for each process wastewater stream, or downstream of 
the point of determination with adjustment for flow rate changes made 
according to Sec. 60.782(c)(4) of this subpart. The annual average flow 
rate for the process wastewater stream shall be representative of the 
actual or anticipated operation of the CPU generating the wastewater 
over the designated 12-month period.

Sec. 60.782  Process wastewater provisions--test methods and procedures 
for determining applicability and Group 1 and Group 2 determinations 
(determining which process wastewater streams require control).

    (a) Procedures to determine applicability. An owner or operator 
shall comply with paragraph (a)(1) or (a)(2) of this section for each 
wastewater stream to determine which wastewater streams require control 
for VOC. The owner or operator may use a combination of the approaches 
in paragraphs (a)(1) and (a)(2) of this

[[Page 68030]]

section for different wastewater streams generated at the affected 
facility.
    (1) Determine Group 1 or Group 2 status. Determine whether a 
wastewater stream is a Group 1 or Group 2 wastewater stream in 
accordance with paragraphs (b) and (c) of this section.
    (2) Designate as Group 1. An owner or operator may designate as a 
Group 1 wastewater stream a single wastewater stream or a mixture of 
wastewater streams. The owner or operator is not required to determine 
the concentration or flow rate for each designated Group 1 wastewater 
stream for the purposes of this section.
    (b) Procedures to establish concentrations, when determining Group 
status under paragraph (a)(1) of this section. An owner or operator who 
elects to comply with the requirements of paragraph (a)(1) of this 
section shall determine the annual average concentration for VOC 
according to paragraph (b)(1) of this section. The annual average 
concentration shall be a flow-weighted average representative of actual 
or anticipated operation of the designated CPU generating the 
wastewater over a designated 12-month period. For flexible operation 
units, the owner or operator shall consider the anticipated production 
over the designated 12-month period and include all wastewater streams 
generated by the process equipment during this period. The owner or 
operator is not required to determine the concentration of VOC that are 
not reasonably expected to be in the process or in the resulting 
wastewater stream.
    (1) General. An owner or operator who elects to comply with the 
requirements of paragraph (a)(1) of this section shall determine the 
flow-weighted annual average concentration for VOC and the range of 
concentrations represented by the flow-weighted annual average 
concentration. For the purposes of this section, the term 
concentration, whether concentration is used alone or with other terms, 
may be adjusted by the compound-specific fraction measured (Fm) 
factors. Compound-specific Fm factors shall be determined as specified 
in appendix J of this part. Flow-weighted annual average concentration 
for VOC means the total mass of VOC occurring in the wastewater stream 
during the designated 12-month period divided by the total mass of the 
wastewater stream during the same designated 12-month period. The 
annual average concentration shall be determined for each wastewater 
stream either at the point of determination, or downstream of the point 
of determination with adjustment for concentration changes made 
according to paragraph (b)(6) of this section. The procedures specified 
in paragraphs (b)(3), (b)(4), and (b)(5) of this section are considered 
acceptable procedures for determining the annual average concentration. 
They may be used in combination, and no one procedure shall take 
precedence over another.
    (2) [Reserved]
    (3) Process knowledge of the wastewater. Where process knowledge is 
used to determine the annual average concentration, the owner or 
operator shall provide sufficient information to document the annual 
average concentration for wastewater streams determined to be Group 2 
wastewater streams as specified in Sec. 60.785(g) of this subpart. 
Documentation to determine the annual average concentration is not 
required for Group 1 streams. Examples of acceptable documentation 
include material balances, records of chemical purchases, process 
stoichiometry, or previous test results. If test data are used, the 
owner or operator shall provide documentation describing the testing 
protocol and the means by which any losses of volatile compounds during 
sampling, and the bias and accuracy of the analytical method, were 
accounted for in the determination.
    (4) Bench-scale or pilot-scale test data. Where bench-scale or 
pilot-scale test data are used to determine the annual average 
concentration, the owner or operator shall provide sufficient 
information to document that the data are representative of the actual 
annual average concentration, or are reliably indicative of another 
relevant characteristic of the wastewater stream that could be used to 
predict the annual average concentration. For concentration data, the 
owner or operator shall also provide documentation describing the 
testing protocol, and the means by which any losses of volatile 
compounds during sampling, and the bias and accuracy of the analytical 
method, were accounted for in the determination of annual average 
concentration.
    (5) Test data from sampling at the point of determination or at a 
location downstream of the point of determination. Where an owner or 
operator elects to comply with paragraph (a)(1) of this section by 
measuring the concentration for VOC, the owner or operator shall comply 
with the requirements of this paragraph (b)(5). For each wastewater 
stream, measurements shall be made either at the point of 
determination, or downstream of the point of determination with 
adjustment for concentration changes made according to paragraph (b)(6) 
of this section. A minimum of three samples from each wastewater stream 
shall be taken. Samples may be grab samples or composite samples.
    (i) Methods. The owner or operator shall use any of the methods 
specified in paragraphs (b)(5)(i)(A) through (b)(5)(i)(F) of this 
section.
    (A) Method 25D. Use procedures specified in Method 25D, 40 CFR part 
60, appendix A.
    (B) Method 305. Use procedures specified in Method 305, 40 CFR part 
63, appendix A .
    (C) Methods 624 and 625. Use procedures specified in Methods 624 
and 625, 40 CFR part 136, appendix A and comply with the sampling 
protocol requirements specified in paragraph (b)(5)(ii) of this 
section. If these methods are used to analyze one or more compounds 
that are not on the method's published list of approved compounds, the 
Alternative Test Procedure specified in 40 CFR part 136.4 and 136.5 
shall be followed. For Method 625, make corrections to the compounds 
for which the analysis is being conducted. The corrections shall be 
based on the accuracy as recovery factors in Table 7 of the method.
    (D) Method 1624 and Method 1625. Use procedures specified in Method 
1624 and Method 1625, 40 CFR part 136, appendix A and comply with the 
requirements specified in paragraph (b)(5)(ii) of this section. If 
these methods are used to analyze one or more compounds that are not on 
the method's published list of approved compounds, the Alternative Test 
Procedure specified in 40 CFR part 136.4 and 136.5 shall be followed.
    (E) Other EPA method(s). Use procedures specified in the method and 
comply with the requirements specified in paragraphs (b)(5)(ii) and 
either paragraph (b)(5)(iii)(A) or (b)(5)(iii)(B) of this section.
    (F) Method(s) other than EPA method. Use procedures specified in 
the method and comply with the requirements specified in paragraphs 
(b)(5)(ii) and (b)(5)(iii)(A) of this section.
    (ii) Sampling plan. The owner or operator who is expressly referred 
to this paragraph (b)(5)(ii) by provisions of this subpart shall 
prepare a sampling plan. Wastewater samples shall be collected using 
sampling procedures which minimize loss of organic compounds during 
sample collection and analysis and maintain sample integrity. The 
sample plan shall include procedures for determining recovery 
efficiency of the relevant VOC. An example of an acceptable sampling 
plan

[[Page 68031]]

would be one that incorporates similar sampling and sample handling 
requirements to those of Method 25D, 40 CFR part 60, appendix A. The 
sampling plan shall be maintained at the facility.
    (iii) Validation of methods. The owner or operator shall validate 
EPA methods other than Methods 25D, 305, 624, 625, 1624, and 1625 using 
the procedures specified in paragraph (b)(5)(iii)(A) or (b)(5)(iii)(B) 
of this section. The owner or operator shall validate other methods as 
specified in paragraph (b)(5)(iii)(A) of this section.
    (A) Validation of EPA methods and other methods. The method used to 
measure VOC concentrations in the wastewater shall be validated 
according to section 5.1 or 5.3, and the corresponding calculations in 
section 6.1 or 6.3, of Method 301 of appendix A of this part. The data 
are acceptable if they meet the criteria specified in section 6.1.5 or 
6.3.3 of Method 301 of appendix A of this part. If correction is 
required under section 6.3.3 of Method 301 of appendix A of this part, 
the data are acceptable if the correction factor is within the range 
0.7 to 1.30. Other sections of Method 301 of appendix A of this part 
are not required. The concentrations of the individual VOC measured in 
the water may be corrected to their concentrations had they been 
measured by Method 25D of appendix A of this part, by multiplying each 
concentration by the compound-specific fraction measured (Fm) factor. 
Compound-specific Fm factors shall be determined as specified in 
appendix J of this part.
    (B) Validation for EPA methods. Follow the procedures as specified 
in ``Alternative Validation Procedure for EPA Waste Methods'' 40 CFR 
part 63, appendix D.
    (iv) Calculations of average concentration. For methods that 
speciate, the average concentration of VOC shall be calculated by first 
summing the concentration of the individual compounds to obtain a total 
VOC concentration for the sample, adding the sample totals, and then 
dividing by the number of samples in the run to obtain the sample 
average for the run. If the method used does not speciate the 
compounds, the sample results should be added and this total divided by 
the number of samples in the run to obtain the sample average for the 
run.
    (6) Adjustment for concentrations determined downstream of the 
point of determination. The owner or operator shall make corrections to 
the annual average concentration when the concentration is determined 
downstream of the point of determination at a location where: two or 
more wastewater streams have been mixed; one or more wastewater streams 
have been treated; or, losses to the atmosphere have occurred. The 
owner or operator shall make the adjustments either to the individual 
data points or to the final annual average concentration.
    (c) Procedures to determine flow rate, when evaluating Group status 
under paragraph (a)(1) of this section. An owner or operator who elects 
to comply with paragraph (a)(1) of this section shall determine the 
annual average flow rate of the wastewater stream and the range of flow 
rates represented by the annual average flow rate. The annual average 
flow rate shall be determined either at the point of determination for 
each wastewater stream, or downstream of the point of determination 
with adjustment for flow rate changes made according to paragraph 
(c)(4) of this section. These procedures may be used in combination for 
different wastewater streams at the affected facility. The annual 
average flow rate for the wastewater stream shall be representative of 
actual or anticipated operation of the designated CPU generating the 
wastewater over a designated 12-month period. The owner or operator 
shall consider the annual wastewater volume generated by the designated 
CPU. If the designated CPU is a flexible operation unit, the owner or 
operator shall consider all anticipated production in the process 
equipment over the designated 12-month period. The procedures specified 
in paragraphs (c)(1), (c)(2), and (c)(3) of this section are considered 
acceptable procedures for determining the flow rate. They may be used 
in combination, and no one procedure shall take precedence over 
another.
    (1) Process knowledge of the wastewater. The owner or operator may 
use process knowledge of the wastewater stream and/or the process to 
determine the annual average flow rate. The owner or operator shall use 
the maximum expected annual average production capacity of the process 
unit, knowledge of the process, and/or mass balance information to 
either estimate the annual average wastewater flow rate directly or 
estimate the total annual wastewater volume and then divide total 
volume by 525,600 minutes in a year. Where process knowledge is used to 
determine the annual average flow rate, the owner or operator shall 
provide sufficient information to document the flow rate for wastewater 
streams determined to be Group 2 wastewater streams as specified in 
Sec. 60.785(g) of this subpart. Documentation to determine the annual 
average flow rate is not required for Group 1 streams.
    (2) Historical records. The owner or operator may use historical 
records to determine the annual average flow rate. Derive the highest 
annual average flow rate of wastewater from historical records 
representing the most recent 5 years of operation or, if the process 
unit has been in service for less than 5 years but at least 1 year, 
from historical records representing the total operating life of the 
process unit. Where historical records are used to determine the annual 
average flow rate, the owner or operator shall provide sufficient

to be Group 2 wastewater streams. Documentation to determine the annual 
average flow rate is not required for Group 1 streams.
    (3) Measurements of flow rate. Where an owner or operator elects to 
comply with paragraph (a)(1) of this section by measuring the flow 
rate, the owner or operator shall comply with the requirements of this 
paragraph (c)(3). Measurements shall be made at the point of 
determination, or at a location downstream of the point of 
determination with adjustments for flow rate changes made according to 
paragraph (c)(4) of this section. Where measurement data are used to 
determine the annual average flow rate, the owner or operator shall 
provide sufficient information to document the flow rate for wastewater 
streams determined to be Group 2 wastewater streams. Documentation to 
determine the annual average flow rate is not required for Group 1 
streams.
    (4) Adjustment for flow rates determined downstream of the point of 
determination. The owner or operator shall make corrections to the 
annual average flow rate of a wastewater stream when it is determined 
downstream of the point of determination at a location where two or 
more wastewater streams have been mixed or one or more wastewater

for such changes in the annual average flow rate.


Sec. 60.783  Process wastewater provisions--test methods and procedures 
to determine compliance.

    (a) General. This section specifies the procedures for performance 
tests that are conducted to demonstrate compliance of a treatment 
process or a control device with the control requirements specified in 
Sec. 60.779 of this subpart. Owners or operators conducting a design 
evaluation shall comply with the requirements of either

[[Page 68032]]

paragraph (a)(1) or (a)(2) of this section. Owners or operators 
conducting a performance test shall comply with the applicable 
requirements in paragraphs (a) through (i) of this section.
    (1) Performance tests and design evaluations for treatment 
processes. If design steam stripper option (Sec. 60.779(d) of this 
subpart) or RCRA option (Sec. 60.779(h)of this subpart) is selected to 
comply with Sec. 60.779 of this subpart, neither a design evaluation 
nor a performance test is required. For any other non-biological 
treatment process, the owner or operator shall conduct either a design 
evaluation as specified in Sec. 60.779(j) of this subpart, or a 
performance test as specified in this section. For closed biological 
treatment processes, the owner or operator shall conduct either a 
design evaluation as specified in Sec. 60.779(j) of this subpart, or a 
performance test as specified in this section. For each open biological 
treatment process, the owner or operator shall conduct a performance 
test as specified in this section.

    Note to paragraph (a)(1): Some open biological treatment 
processes may not require a performance test. Refer to paragraph (h) 
of this section to determine whether the biological treatment 
process meets the criteria that exempt the owner or operator from 
conducting a performance test.

    (2) Performance tests and design evaluations for control devices. 
The owner or operator shall conduct either a design evaluation as 
specified in Sec. 60.780(d) of this subpart, or a performance test as 
specified in paragraph (i) of this section for control devices other 
than flares and paragraph (j) of this section for flares.
    (3) Performance tests and compliance determinations shall be 
conducted according to the schedule and procedures in 40 CFR 63.7(a) 
and table 2A of this subpart, and the applicable sections of this 
subpart.
    (4) The owner or operator shall notify the Administrator of the 
intention to conduct a performance test at least 30 calendar days 
before the performance test is scheduled to allow the Administrator the 
opportunity to have an observer present during the test.
    (5) Performance tests shall be conducted according to the 
provisions of 40 CFR 63.7(e)(1) through (e)(2) and (e)(4) and table 2A 
of this subpart, except that performance tests shall be conducted at 
maximum representative operating conditions for the process. During the 
performance test, an owner or operator may operate the control or 
recovery device at maximum or minimum representative operating 
conditions for monitored control or recovery device parameters, 
whichever results in lower emission reduction.
    (6) Data shall be reduced in accordance with the EPA-approved 
methods specified in the applicable subpart or, if other test methods 
are used, the data and methods shall be validated according to the 
protocol in Method 301 of appendix A of 40 CFR part 63.
    (7) Performance tests may be waived with approval of the 
Administrator as specified in 40 CFR 63.7(h)(2) and table 2A of this 
subpart. Owners or operators who apply for a waiver of a performance 
test shall submit the application by the dates specified in paragraph 
(b)(7)(i) of this section.
    (i) The application for a waiver of an initial performance test 
shall be submitted not later than 90 calendar days before the 
Notification of Compliance Status required in Sec. 60.784(c) of this 
subpart is due to be submitted.
    (ii) Any application for a waiver of a performance test shall 
include information justifying the owner or operator's request for a 
waiver, such as the technical or economic infeasibility, or the 
impracticality, of the affected facility performing the required test.
    (8) Representative process unit operating conditions. Compliance 
shall be demonstrated for representative operating conditions. 
Operations during periods of start-up, shutdown, or malfunction and 
periods of non-operation shall not constitute representative 
conditions. The owner or operator shall record the process information 
that is necessary to document operating conditions during the test.
    (9) Representative treatment process or control device operating 
conditions. Performance tests shall be conducted when the treatment 
process or control device is operating at a representative inlet flow 
rate and concentration. If the treatment process or control device will 
be operating at several different sets of representative operating 
conditions, the owner or operator shall comply with paragraphs 
(a)(9)(i) and (a)(9)(ii) of this section. The owner or operator shall 
record information that is necessary to document treatment process or 
control device operating conditions during the test.
    (i) Range of operating conditions. If the treatment process or 
control device will be operated at several different sets of 
representative operating conditions, performance testing over the 
entire range is not required. In such cases, the performance test 
results shall be supplemented with modeling and/or engineering 
assessments to demonstrate performance over the operating range.
    (ii) Consideration of residence time. If concentration and/or flow 
rate to the treatment process or control device are not relatively 
constant (i.e., comparison of inlet and outlet data will not be 
representative of performance), the owner or operator shall consider 
residence time, when determining concentration and flow rate.
    (10) Testing equipment. All testing equipment shall be prepared and 
installed as specified in the applicable test methods, or as approved 
by the Administrator.
    (11) Compounds not required to be considered in performance tests 
or design evaluations. This paragraph (a)(11) applies only when test 
methods that speciate compounds are used. Compounds that meet the 
requirements specified in paragraphs (a)(11)(i), (a)(11)(ii), or 
(a)(11)(iii) of this section are not required to be included in the 
performance test.
    (i) Compounds not used or produced by the chemical process unit; or
    (ii) Compounds with concentrations at the point of determination 
that are below 1 part per million by weight; or
    (iii) Compounds with concentrations at the point of determination 
that are below the lower detection limit where the lower detection 
limit is greater than 1 part per million by weight. The method shall be 
an analytical method for wastewater which has that compound as a target 
analyte.
    (12) Treatment using a series of treatment processes. In all cases 
where the wastewater provisions in this subpart allow or require the 
use of a treatment process to comply with emission limitations, the 
owner or operator may use multiple treatment processes. The owner or 
operator complying with the requirements of Sec. 60.779(a)(12)(i) of 
this subpart, when wastewater is conveyed by hard-piping, shall comply 
with either paragraph (a)(12)(i) or (a)(12)(ii) of this section. The 
owner or operator complying with the requirements of 
Sec. 60.779(a)(12)(ii) of this subpart shall comply with the 
requirements of paragraph (a)(12)(ii) of this section.
    (i) The owner or operator shall conduct the performance test across 
each series of treatment processes. For each series of treatment 
processes, inlet concentration and flow rate shall be measured either 
where the wastewater stream enters the first treatment process in a 
series of treatment processes, or prior to the first treatment process 
as specified in paragraph (a)(14) of this section. For each series of 
treatment processes, outlet concentration and flow

[[Page 68033]]

rate shall be measured where the wastewater stream exits the last 
treatment process in the series of treatment processes, except when the 
last treatment process is an open or a closed aerobic biological 
treatment process demonstrating compliance by using the procedures in 
paragraphs (f) or (g) of this section. When the last treatment process 
is either an open or a closed aerobic biological treatment process 
demonstrating compliance by using the procedures in paragraphs (f) or 
(g) of this section, inlet and outlet concentrations and flow rates 
shall be measured as provided in paragraphs (a)(12)(i)(A) and 
(a)(12)(i)(B) of this section. The mass flow rates removed or destroyed 
by the series of treatment processes and by the biological treatment 
process are all used to calculate actual mass removal (AMR) as 
specified in paragraph (f)(5)(ii) of this section.
    (A) The inlet and outlet to the series of treatment processes prior 
to the biological treatment process are the points at which the 
wastewater enters the first treatment process and exits the last 
treatment process in the series, respectively, except as provided in 
paragraph (a)(14)(ii) of this section.
    (B) The inlet to the biological treatment process shall be the 
point at which the wastewater enters the biological treatment process 
or the outlet from the series of treatment processes identified in 
paragraph (a)(12)(i)(A) of this section, except as provided in 
paragraph (a)(14)(ii) of this section.
    (ii) The owner or operator shall conduct the performance test 
across each treatment process in the series of treatment processes. The 
mass flow rate removed or destroyed by each treatment process shall be 
added together to determine whether compliance has been demonstrated 
using paragraphs (c), (d), (e), (f), and (g) of this section, as 
applicable. If a biological treatment process is one of the treatment 
processes in the series of treatment processes, the inlet to the 
biological treatment process shall be the point at which the wastewater 
enters the biological treatment process or the inlet to the 
equalization tank if all the criteria of paragraph (a)(14)(ii) of this 
section are met.
    (13) When using a biological treatment process to comply with 
Sec. 60.779 of this subpart, the owner or operator may elect to 
calculate the AMR using a subset of VOC determined at the point of 
determination or downstream of the point of determination with 
adjustment for concentration and flowrate changes made according to 
Sec. 60.782(b)(6) and (c)(4), respectively, of this subpart. All VOC 
measured to determine the RMR, except as provided by paragraph (a)(11) 
of this section, shall be included in the RMR calculation.
    (14) The owner or operator determining the inlet for purposes of 
demonstrating compliance with paragraphs (e), (f), or (g) of this 
section may elect to comply with paragraph (a)(14)(i) or (a)(14)(ii) of 
the section.
    (i) When wastewater is conveyed exclusively by hard-piping from the 
point of determination to a treatment process that is either the only 
treatment process or the first in a series of treatment processes 
(i.e., no treatment processes or other waste management units are used 
upstream of this treatment process to store, handle, or convey the 
wastewater), the inlet to the treatment process shall be at any 
location from the point of determination to where the wastewater stream 
enters the treatment process. When samples are taken upstream of the 
treatment process and before wastewater streams have converged, the 
owner or operator shall ensure that the mass flow rate of all Group 1 
wastewater streams is accounted for when using Sec. 60.779(e) or (f) of 
this subpart to comply and that the mass flow rate of all Group 1 and 
Group 2 wastewater streams is accounted for when using Sec. 60.779(g) 
of this subpart to comply, except as provided in Sec. 60.779(a)(6) of 
this subpart.
    (ii) The owner or operator may consider the inlet to the 
equalization tank as the inlet to the biological treatment process if 
all the criteria in paragraphs (a)(14)(ii)(A) through (a)(14)(ii)(C) of 
this section are met. The outlet from the series of treatment processes 
prior to the biological treatment process is the point at which the 
wastewater exits the last treatment process in the series prior to the 
equalization tank, if the equalization tank and biological treatment 
process are part of a series of treatment processes. The owner or 
operator shall ensure that the mass flow rate of all Group 1 wastewater 
streams is accounted for when using Sec. 60.779(e) or (f) of this 
subpart to comply and that the mass flow rate of all Group 1 and Group 
2 wastewater streams is accounted for when using Sec. 60.779(g) of this 
subpart to comply, except as provided in paragraph (a)(11) of this 
section.
    (A) The wastewater is conveyed by hard-piping from either the last 
previous treatment process or the point of determination to the 
equalization tank.
    (B) The wastewater is conveyed from the equalization tank 
exclusively by hard-piping to the biological treatment process and no 
treatment processes or other waste management units are used to store, 
handle, or convey the wastewater between the equalization tank and the 
biological treatment process.
    (C) The equalization tank is equipped with a fixed roof and a 
closed vent system that routes VOC emissions to a control device that 
meets the requirements of 40 CFR 63.133(a)(2)(i) and (b)(1) through 
(b)(4).

this subpart. The method shall be an analytical method for wastewater 
which has that compound as a target analyte. Samples may be grab 
samples or composite samples. Samples shall be taken at approximately 
equally spaced time intervals over a 1-hour period. Each 1-hour period 
constitutes a run, and the performance test shall consist of a minimum 
of 3 runs.
    (2) Flow rate. The flow rate of the entering and exiting wastewater 
streams shall be determined using inlet and outlet flow meters, 
respectively. Where the outlet flow is not greater than the inlet flow,

measurements to determine RMR shall be taken at the point of 
determination or downstream of the point of determination with 
adjustment for concentration change made according to Sec. 60.782(b)(6) 
of this subpart. Concentration measurements to determine AMR shall be

tests that are conducted for open or closed aerobic biological 
treatment processes to demonstrate compliance with the 95-percent mass 
removal provisions for VOC. This compliance option is specified in 
Sec. 60.779(g) of this subpart. The RMR for this option is 95-percent 
mass removal. The owner or operator shall comply with the requirements 
specified in paragraphs (g)(1) of this section to determine AMR, 
paragraphs (e)(3)(ii) and (e)(4)(ii) of this section to determine RMR, 
and paragraph (g)(2) of this section to determine whether compliance 
has been demonstrated. Some compounds may not require a performance 
test. Refer to paragraph (h) of this section and Table 14 of this 
subpart to determine which compounds may be exempt from the 
requirements of this paragraph (g).
    (1) The owner or operator shall comply with the requirements 
specified in paragraphs (f)(1), (f)(2), and (f)(5) of this section to 
determine AMR. References to Group 1 wastewater streams shall be deemed

treatment process meets the definition of ``enhanced biological 
treatment process'' in Sec. 60.771 of this subpart and the wastewater 
streams include one or more compounds not on Table 14 of this subpart 
that do not meet the criteria in paragraph (h)(1)(ii) of this section, 
the owner or operator shall determine Fbio for VOC not on 
Table 14 of this subpart using any of the procedures specified in 40 
CFR part 63, appendix C. (stream-specific list) (The symbol

specified in Sec. 60.780(c) of this subpart. If complying with the 95-
percent reduction efficiency requirement, comply with the requirements 
specified in paragraphs (i)(1) through (i)(9) of this section. If 
complying with the 20 ppm by volume requirement, comply with the 
requirements specified in paragraphs (i)(1) through (i)(6) and (i)(9) 
of this section. The 20 ppm by volume limit or 95 percent reduction 
efficiency requirement shall be measured as either total VOC or as TOC

combustion device. The emission rate correction factor for excess air, 
composite sampling (i.e., integrated sampling) and analysis procedures 
of Method 3B, 40 CFR part 60, appendix A shall be used to determine the 
actual oxygen concentration (%02d). The samples shall be taken during 
the same time that the TOC (minus methane or ethane) or total VOC 
samples are taken.
    (ii) 3 percent oxygen calculation. The concentration corrected to 3 
percent oxygen (CGc), when required, shall be computed using the 
following equation:

ethane) or total VOC, in vented gas stream entering and exiting 
(QMGb) the control device, dry basis, kilograms per hour.

    (9) Compare mass destruction efficiency to required efficiency. If 
complying with the 95 percent reduction efficiency requirement, 
compliance is demonstrated if the mass destruction efficiency 
(calculated in Equation WW18) is 95 percent or greater. If complying 
with the 20 parts per million by volume limit in Sec. 60.780(c) of this 
subpart, compliance is demonstrated if the outlet total organic 
compound concentration, less methane and ethane, or total VOC 
concentration is 20 parts per million by volume, or less. For 
combustion control devices, the concentration shall be calculated on a 
dry basis, corrected to 3 percent oxygen.

in paragraphs (h)(1) through (h)(3) of this section, that compliance 
demonstration may be used to satisfy the requirements of this paragraph 
(j) if either no deliberate process changes have been made since the 
compliance demonstration, or the results of the compliance 
demonstration reliably demonstrate compliance despite process changes.

    (1) [Reserved]
    (2) The semiannual report shall include reports of all excursions 
and all periods when monitoring parameters are above the maximum or 
below the minimum established value.
    (3) The semiannual report shall include the daily average values of 
monitored parameters for all excursions, as defined by paragraphs 
(d)(3)(i), (d)(3)(ii), or (d)(3)(iii) of this section. For excursions 
caused by lack of monitoring data, the duration of periods when 
monitoring data were not collected shall be reported. For a control 
device where multiple parameters are monitored, if one or more of the 
parameters meets the excursion criteria in paragraphs (d)(3)(i), 
(d)(3)(ii), or (d)(3)(iii) of this section, this is considered a single 
excursion for the control device.
    (i) When the daily average value of one or more monitored 
parameters is above the maximum or below the minimum (as appropriate) 
established operating parameter value.
    (ii) When the period of control device operation is 4 hours or 
greater in an operating day and monitoring data are insufficient to 
constitute a valid hour of data for at least 75 percent of the 
operating hours.
    (iii) When the period of control device operation is less than 4 
hours in an operating day and more than one of the hours during the 
period of operation does not constitute a valid hour of data due to 
insufficient monitoring data.
    (iv) Monitoring data are insufficient to constitute a valid hour of 
data, as used in paragraphs (d)(3)(ii) and (d)(3)(iii) of this section, 
if measured values are unavailable for any of the 15-minute periods 
within the hour. For data compression systems approved under paragraph 
(b)(4) of this section, monitoring data are insufficient to calculate a 
valid hour of data if there are less than 4 data values recorded during 
the hour.
    (4) Each control device is allowed one excused excursion per 
semiannual period. The first semiannual period is the 6-month period 
covered by the first semiannual report.
    (5)(i) Paragraphs (d)(5)(i)(A) through (d)(5)(i)(D) of this section 
specify when an excursion is not a violation. In cases where continuous 
monitoring is required, the excursion does not count toward the number 
of excused excursions for determining compliance.

up, shutdown, or malfunction and the

[[Page 68043]]

affected facility is operated during such period in accordance with the 
affected facility's start-up, shutdown, and malfunction plan, or
    (D) If cessation of the emissions to which the monitoring applies 
occurs during periods of non-operation of the chemical process unit or 
portion thereof.
    (ii) Nothing in paragraphs (d)(3) through (d)(5) of this section 
shall be construed to allow or excuse a monitoring parameter excursion 
caused by any activity that violates other applicable provisions of 
this subpart.
    (iii) Paragraphs (d)(3) through (d)(5) of this section, except 
paragraph (d)(5)(i) of this section, shall apply only to emission 
points and control devices for which continuous monitoring is required 
by this subpart.
    (6) The semiannual report shall include results of any performance 
tests conducted during the reporting period including one complete 
report for each test method used for a particular kind of emission 
point tested. For additional tests performed for a similar emission 
point using the same method, results and any other information required 
shall be submitted, but a complete test report is not required. A 
complete test report shall contain a brief process description, 
sampling site data, description of sampling and analysis procedures and 
any modifications to standard procedures, quality assurance procedures, 
record of operating conditions during the test, record of preparation 
of standards, record of calibrations, raw data sheets for field 
sampling, raw data sheets for field and laboratory analyses, 
documentation of calculations, and any other information required by 
the test method.

Sec. 60.785(f)(10) of this subpart when the vent is diverted from the 
control device through a bypass line, with the next semiannual report.
    (10) The semiannual report shall include notification of all 
occurrences recorded under Sec. 60.785(f)(11) of this subpart in which 
the seal mechanism is broken, the bypass line damper or valve position 
has changed, or the key to unlock the bypass line damper or valve was 
checked out, with the next semiannual report.
    (11) The semiannual report shall include notification that 
semiannual report information for waste management units will be 
submitted with semiannual reports required by another rule that is one 
of the compliance options for waste management units as specified in 
Sec. 60.784 of this subpart.
    (12) The semiannual report shall include notification of each 
affected facility that ceases to generate at least one process 
wastewater stream or aqueous in-process stream or no longer produces a 
primary product that is a SOCMI product.
    (e) Semiannual reporting for treatment processes. Except as 
provided in paragraph (g) of this section, for each treatment process 
used to comply with this subpart, the owner or operator shall submit as 
part of the next semiannual report required by paragraph (d) of this 
section the information specified in paragraphs (e)(1) and (e)(2) of

this section as alternatives to the continuous operating parameter 
monitoring and recordkeeping provisions specified in this subpart. The 
owner or operator shall retain for a period of 5 years each record 
required by paragraph (j)(1) or (j)(2) of this section.
    (1) The owner or operator may retain only the daily average value, 
and is not required to retain more frequent monitored operating 
parameter values, for a monitored parameter with respect to an item of 
equipment, if the requirements of paragraphs (j)(1)(i) through 
(j)(1)(vi) of this section are met. An owner or operator electing to 
comply with the requirements of paragraph (j)(1) of this section shall 
notify the Administrator in the Notification of Compliance Status as 
specified in Sec. 60.784(c)(13) of this subpart or, if the Notification 
of Compliance Status has already been submitted, in the semiannual 
report immediately preceding implementation of the requirements of 
paragraph (j)(1) of this section as specified in Sec. 60.784(d)(7) of 
this subpart.
    (i) The monitoring system is capable of detecting unrealistic or 
impossible data during periods of operation other than start-ups, 
shutdowns, or malfunctions (e.g., a temperature reading of -200 deg.C 
on a boiler), and will alert the operator by alarm or other means. The 
owner or operator shall record the occurrence. All instances of the 
alarm or other alert in an operating day constitute a single 
occurrence.
    (ii) The monitoring system generates, updated at least hourly 
throughout each operating day, a running average of the monitoring 
values that have been obtained during that operating day, and the 
capability to observe this running average is readily available to the 
Administrator on-site during the operating day. The owner or operator 
shall record the occurrence of any period meeting the criteria in 
paragraphs (j)(1)(ii)(A) through (j)(1)(ii)(C) of this section. All 
instances in an operating day constitute a single occurrence.
    (A) The running average is above the maximum or below the minimum 
established limits;
    (B) The running average is based on at least six 1-hour average 
values; and
    (C) The running average reflects a period of operation other than a 
start-up, shutdown, or malfunction.
    (iii) The monitoring system is capable of detecting unchanging data 
during periods of operation other than start-ups, shutdowns, or 
malfunctions, except in circumstances where the presence of unchanging 
data is the expected operating condition based on past experience 
(e.g., pH in some scrubbers), and will alert the operator by alarm or 
other means. The owner or operator shall record the occurrence. All 
instances of the alarm or other alert in an operating day constitute a 
single occurrence.
    (iv) The monitoring system will alert the owner or operator by an 
alarm or other means, if the running average parameter value calculated 
under paragraph (j)(1)(ii) of this section reaches a set point that is 
appropriately related to the established limit for the parameter that 
is being monitored.
    (v) The owner or operator shall verify the proper functioning of 
the monitoring system, including its ability to comply with the 
requirements of paragraph (j)(1) of this section, at the times 
specified in paragraphs (j)(1)(v)(A) through (j)(1)(v)(C). The owner or 
operator shall document that the required verifications occurred.
    (A) Upon initial installation.
    (B) Annually after initial installation.
    (C) After any change to the programming or equipment constituting 
the monitoring system, which might reasonably be expected to alter the 
monitoring system's ability to comply with the requirements of this 
section.
    (vi) The owner or operator shall retain the records identified in 
paragraphs (j)(1)(vi)(A) through (j)(1)(vi)(D) of this section.
    (A) Identification of each parameter, for each item of equipment, 
for which the owner or operator has elected to comply with the 
requirements of paragraph (j) of this section.
    (B) A description of the applicable monitoring system(s), and of 
how compliance will be achieved with each requirement of paragraphs 
(j)(1)(i) through (j)(1)(v) of this section. The description shall 
identify the location and format (e.g., on-line storage, log entries) 
for each required record. If the description changes, the owner or 
operator shall retain both the current and the most recent superseded 
description, as provided in paragraph (a) of this section, except as 
provided in paragraph (j)(1)(vi)(D) of this section.
    (C) A description, and the date, of any change to the monitoring 
system that would reasonably be expected to impair its ability to 
comply with the requirements of paragraph (j)(1) of this section.
    (D) Owners and operators subject to paragraph (j)(1)(vi)(B) of this 
section shall retain the current description of the monitoring system 
as long as the description is current, but not less than 5 years from 
the date of its creation. The current description shall, at all times, 
be retained on-site or be accessible from a central location by 
computer or other means that provides access within 2

[[Page 68046]]

hours after a request. The owner or operator shall retain all 
superseded descriptions for at least 5 years after the date of their 
creation. Superseded descriptions shall be retained on-site (or 
accessible from a central location by computer or other means that 
provides access within 2 hours after a request) for at least 6 months 
after their creation. Thereafter, superseded descriptions may be stored 
off-site.
    (2) If an owner or operator has elected to implement the 
requirements of paragraph (j)(1) of this section for a monitored 
parameter with respect to an item of equipment and a period of 6 
consecutive months has passed without an excursion as defined in 
paragraph (j)(2)(iv) of this section, the owner or operator is no 
longer required to record the daily average value for any operating day 
when the daily average value is less than the maximum or greater than 
the minimum established limit. With approval by the Administrator, 
monitoring data generated prior to the compliance date of this subpart 
shall be credited toward the period of 6 consecutive months, if the 
parameter limit and the monitoring accomplished during the period prior 
to the compliance date was required and/or approved by the 
Administrator.
    (i) If the owner or operator elects not to retain the daily average 
values, the owner or operator shall notify the Administrator in the 
next semiannual report as specified in Sec. 60.784(d)(8) of this 
subpart. The notification shall identify the parameter and unit of 
equipment.
    (ii) If, on any operating day after the owner or operator has 
ceased recording daily average values as provided in paragraph (j)(2) 
of this section, there is an excursion as defined in paragraph 
(j)(2)(iv) of this section, the owner or operator shall immediately 
resume retaining the daily average value for each operating day and 
shall notify the Administrator in the next semiannual report. The owner 
or operator shall continue to retain each daily average value until 
another period of 6 consecutive months has passed without an excursion 
as defined in paragraph (j)(2)(iv) of this section.
    (iii) The owner or operator shall retain the records specified in 
paragraphs (j)(1)(i) through (j)(1)(iv) of this section, for the 
duration specified in paragraph (j) of this section. For any calendar 
week, if compliance with paragraphs (j)(1)(i) through (j)(1)(iv) of 
this section does not result in retention of a record of at least one 
occurrence or measured parameter value, the owner or operator shall 
record and retain at least one parameter value during a period of 
operation other than a start-up, shutdown, or malfunction.
    (iv) For purposes of paragraph (j) of this section, an excursion 
means that the daily average value of monitoring data for a parameter 
is greater than the maximum, or less than the minimum established 
value, except that the daily average value during any start-up, 
shutdown, or malfunction shall not be considered an excursion for 
purposes of paragraph (j)(2) of this section, if the owner or operator 
follows the applicable provisions of the start-up, shutdown, and 
malfunction plan required by Sec. 60.787 of this subpart. An excused 
excursion, as described in Sec. 60.784(d)(4) of this subpart, shall not 
be considered an excursion for purposes of this paragraph (j)(2).


Sec. 60.786  Leak inspection provisions.

    (a) For each vapor collection system, closed-vent system, fixed 
roof, cover, or enclosure required to comply with this section, the 
owner or operator shall comply with the requirements of paragraphs (b) 
through (i) of this section, unless otherwise specified in this 
subpart.
    (b) Except as provided in paragraphs (g) and (h) of this section, 
each vapor collection system and closed-vent system shall be inspected 
according to the procedures and schedule specified in paragraphs (b)(1) 
and (b)(2) of this section and each fixed roof, cover, and enclosure 
shall be inspected according to the procedures and schedule specified 
in paragraph (b)(3) of this section.
    (1) If the vapor collection system or closed vent system is 
constructed of hard-piping, the owner or operator shall:
    (i) Conduct an initial inspection according to the procedures in 
paragraph (c) of this section; and
    (ii) Conduct annual visual inspections for visible, audible, or 
olfactory indications of leaks.
    (2) If the vapor collection system or closed vent system is 
constructed of duct work, the owner or operator shall:
    (i) Conduct an initial inspection according to the procedures in 
paragraph (c) of this section, and
    (ii) Conduct annual visual inspections for visible, audible, or 
olfactory indications of leaks.
    (2) If the vapor collection system or closed vent system is 
constructed of duct work, the owner or operator shall:
    (i) Conduct an initial inspection according to the procedures in 
paragraph (c) of this section; and
    (ii) Conduct annual inspections according to the procedures in 
paragraph (c) of this section.
    (iii) Conduct annual visual inspections for visible, audible, or 
olfactory indications of leaks.
    (3) For each fixed roof, cover, and enclosure, the owner or 
operator shall:
    (i) Conduct an initial inspection according to the procedures in 
paragraph (c) of this section; and
    (ii) Conduct semi-annual visual inspections for visible, audible, 
or olfactory indications of leaks.
    (c) Each vapor collection system, closed vent system, fixed roof, 
cover, and enclosure shall be inspected according to the procedures 
specified in paragraphs (c)(1) through (c)(6) of this section.
    (1) Inspections shall be conducted in accordance with Method 21, 40 
CFR part 60, appendix A, and with the exceptions and modifications 
specified in this subpart.
    (2) The detection instrument shall meet the performance criteria of 
Method 21, 40 CFR part 60, appendix A except the instrument response 
factor criteria in Section 3.1.2(a) of Method 21 shall be for the 
average composition of the process fluid not each individual VOC in the 
stream.
    (i) Except as provided in paragraph (c)(2)(ii) of this section, the 
detection instrument shall meet the performance criteria of Method 21, 
40 CFR part 60, appendix A, except the instrument response factor 
criteria in section 3.1.2(a) of Method 21 shall be for the average 
composition of the process fluid not each individual VOC in the stream. 
For process streams that contain nitrogen, air, or other inerts which 
are not organic hazardous air pollutants or VOCs, the average stream 
response factor shall be calculated on an inert-free basis.
    (ii) If no instrument is available at the plant site that will meet 
the performance criteria specified in paragraph (c)(2)(i) of this 
section, the instrument readings may be adjusted by multiplying by the 
average response factor of the process fluid, calculated on an inert-
free basis as described in paragraph (c)(2)(i) of this section.
    (3) The detection instrument shall be calibrated before use on each 
day of its use by the procedures specified in Method 21, 40 CFR part 
60, appendix A.
    (4) Calibration gases shall be as follows:
    (i) Zero air (less than 10 parts per million hydrocarbon in air); 
and
    (ii) Mixtures of methane in air at a concentration less than 10,000 
parts per million. A calibration gas other than methane in air may be 
used if the instrument does not respond to methane or if the instrument 
does not meet the performance criteria specified in

[[Page 68047]]

paragraph (c)(2)(i) of this section. In such cases, the calibration gas 
may be a mixture of one or more of the compounds to be measured in the 
air.
    (5) An owner or operator may elect to adjust or not adjust 
instrument readings for background. If an owner or operator elects to 
not adjust readings for background, all such instrument readings shall 
be compared directly to the applicable leak definition to determine 
whether there is a leak. If an owner or operator elects to adjust 
instrument readings for background, the owner or operator shall measure 
background concentration using the procedures in 40 CFR 63.180(b) and 
(c). The owner or operator shall subtract background reading from the 
maximum concentration indicated by the instrument.
    (6) The arithmetic difference between the maximum concentration 
indicated by the instrument and the background level shall be compared 
with 500 parts per million for determining compliance.
    (d) Leaks, as indicated by an instrument reading greater than 500 
parts per million above background or by visual inspections, shall be 
repaired as soon as practical, except as provided in paragraph (e) of 
this section.
    (1) A first attempt at repair shall be made no later than 5 
calendar days after the leak is detected.
    (2) Repair shall be completed no later than 15 calendar days after 
the leak is detected.
    (e) Delay of repair of a vapor collection system, closed vent 
system, fixed roof, cover, or enclosure for which leaks have been 
detected is allowed if the repair is technically infeasible without a 
shutdown or if the owner or operator determines that emissions 
resulting from immediate repair would be greater than the fugitive 
emissions likely to result from delay of repair. Repair of such 
equipment shall be complete by the end of the next shutdown.
    (f) For each vapor collection system or closed vent system that 
contains bypass lines that could divert emissions away from a control 
device, the owner or operator shall comply with the provisions of 
either paragraph (f)(1) or (f)(2) of this section. Equipment such as 
low leg drains, high point bleeds, analyzer vents, open-ended valves or 
lines, and pressure relief valves needed for safety purposes are not 
subject to this paragraph (f).
    (1) Properly install, maintain, and operate a flow indicator that 
takes a reading at least once every 15 minutes. Records shall be 
generated as specified in Sec. 60.785(f)(10) of this subpart. The flow 
indicator shall be installed at the entrance to any bypass line that 
could divert emissions away from the control device and to the 
atmosphere; or
    (2) Secure the bypass line damper or valve in the non-diverting 
position with a car-seal or a lock-and-key type configuration. A visual 
inspection of the seal or closure mechanism shall be performed at least 
once every month to ensure that the damper or valve is maintained in 
the non-diverting position and emissions are not diverted through the 
bypass line. Records shall be generated as specified in 
Sec. 60.785(e)(11) of this subpart.
    (g) Any parts of the vapor collection system, closed vent system, 
fixed roof, cover, or enclosure that are designated, as described in 
paragraph (i)(1) of this section, as unsafe to inspect are exempt from 
the inspection requirements of paragraphs (b)(1), (b)(2), and (b)(3)(i) 
of this section if:
    (1) The owner or operator determines that the equipment is unsafe 
to inspect because inspecting personnel would be exposed to an imminent 
or potential danger as a consequence of complying with paragraphs 
(b)(1), (b)(2), or (b)(3)(i) of this section; and
    (2) The owner or operator has a written plan that requires 
inspection of the equipment as frequently as practicable during safe-
to-inspect times.
    (h) Any parts of the vapor collection system, closed vent system, 
fixed roof, cover, or enclosure that are designated, as described in 
paragraph (i)(2) of this section, as difficult to inspect are exempt 
from the inspection requirements of paragraphs (b)(1), (b)(2), and 
(b)(3)(i) of this section if:
    (1) The owner or operator determines that the equipment cannot be 
inspected without elevating the inspecting personnel more than 2 meters 
above a support surface; and
    (2) The owner or operator has a written plan that requires 
inspection of the equipment at least once every 5 years.
    (i) The owner or operator shall record the information specified in 
paragraphs (i)(1) through (i)(5) of this section.
    (1) Identification of all parts of the vapor collection system, 
closed vent system, fixed roof, cover, or enclosure that are designated 
as unsafe to inspect, an explanation of why the equipment is unsafe to 
inspect, and the plan for inspecting the equipment.
    (2) Identification of all parts of the vapor collection system, 
closed vent system, fixed roof, cover, or enclosure that are designated 
as difficult to inspect, an explanation of why the equipment is 
difficult to inspect, and the plan for inspecting the equipment.
    (3) For each vapor collection system or closed vent system that 
contains bypass lines that could divert a vent stream away from the 
control device and to the atmosphere, the owner or operator shall keep 
a record of the information specified in either paragraph (i)(3)(i) or 
(i)(3)(ii) of this section.
    (i) Hourly records of whether the flow indicator specified under 
paragraph (f)(1) of this section was operating and whether a diversion 
was detected at any time during the hour, as well as records of the 
times of all periods when the vent stream is diverted from the control 
device or the monitor is not operating.
    (ii) Where a seal mechanism is used to comply with paragraph (f)(2) 
of this section, hourly records of flow are not required. In such 
cases, the owner or operator shall record whether the monthly visual 
inspection of the seals or closure mechanisms has been done, and shall 
record the occurrence of all periods when the seal mechanism is broken, 
the bypass line valve position has changed, or the key for a lock-and-
key type configuration has been checked out, and records of any car-
seal that has broken.
    (4) For each inspection during which a leak is detected, a record 
of the information specified in paragraphs (i)(4)(i) through 
(i)(4)(viii) of this section.
    (i) The instrument identification numbers; the name or initials of 
the person conducting the inspection; and identification of the 
equipment.
    (ii) The date the leak was detected and the date of the first 
attempt to repair the leak.
    (iii) Maximum instrument reading measured by the method specified 
in paragraph (d) of this section after the leak is successfully 
repaired or determined to be nonrepairable.
    (iv) ``Repair delayed'' and the reason for the delay if a leak is 
not repaired within 15 calendar days after discovery of the leak.
    (v) The name, initials, or other form of identification of the 
owner or operator (or designee) whose decision it was that repair could 
not be effected without a shutdown.
    (vi) The expected date of successful repair of the leak if a leak 
is not repaired within 15 calendar days.
    (vii) Dates of shutdowns that occur while the equipment is 
unrepaired.
    (viii) The date of successful repair of the leak.
    (5) For each inspection conducted in accordance with paragraph (c) 
of this section during which no leaks are detected, a record that the 
inspection was performed, the date of the

[[Page 68048]]

inspection, and a statement that no leaks were detected.
    (6) For each visual inspection conducted in accordance with 
paragraph (b)(1)(ii) or (b)(3)(ii) of this section during which no 
leaks are detected, a record that the inspection was performed, the 
date of the inspection, and a statement that no leaks were detected.


Sec. 60.787  Additional Requirements--Start-up, Shutdown, Malfunction, 
or Nonoperation; Alternative Means of Emission Limitation; and Permits

    (a) Applicability of this subpart during periods of start-up, 
shutdown, malfunction, or non-operation. Paragraphs (a)(1) through 
(a)(4) of this section shall be followed during periods of start-up, 
shutdown, malfunction, or non-operation of the affected facility or any 
part thereof.
    (1) The emission limitations set forth in this subpart and the 
emission limitations referred to in this subpart shall apply at all 
times except during periods of non-operation of the affected facility 
(or specific portion thereof) resulting in cessation of the emissions 
to which this subpart applies. The emission limitations of this subpart 
and the emission limitations referred to in this subpart shall not 
apply during periods of start-up, shutdown, or malfunction. During 
periods of start-up, shutdown, or malfunction, the owner or operator 
shall follow the applicable provisions of the start-up, shutdown, and 
malfunction plan as specified in 40 CFR 63.6(e)(3) and table 2A of this 
subpart. However, if a start-up, shutdown, malfunction, or period of 
non-operation of one portion of an affected facility does not affect 
the ability of a particular emission point to comply with the emission 
limitations to which it is subject, then that emission point shall 
still be required to comply with the applicable provisions of this 
subpart during the start-up, shutdown, malfunction, or period of non-
operation.
    (2) The owner or operator shall not shut down items of equipment 
that are required or utilized for compliance with this subpart during 
periods of start-up, shutdown, or malfunction during times when 
emissions, wastewater streams, or residuals are being routed to such 
items of equipment, if the shutdown would contravene requirements of 
this subpart applicable to such items of equipment. This paragraph 
(a)(2) does not apply if the item of equipment is malfunctioning. This 
paragraph (a)(2) also does not apply if the owner or operator shuts 
down the compliance equipment (other than monitoring systems) to avoid 
damage due to a contemporaneous start-up, shutdown, or malfunction of 
the affected facility or portion thereof. If the owner or operator has 
reason to believe that monitoring equipment would be damaged due to a 
contemporaneous start-up, shutdown, or malfunction of the affected 
facility or portion thereof, the owner or operator shall provide 
documentation to the Administrator, as soon as possible, supporting 
such a claim. Once approved by the Administrator, the provision for 
ceasing to collect, during a start-up, shutdown, or malfunction, 
monitoring data that would otherwise be required by the provisions of 
this subpart must be incorporated into the start-up, shutdown, 
malfunction plan for that affected facility.
    (3) During start-ups, shutdowns, and malfunctions when the emission 
limitations of this subpart do not apply pursuant to paragraphs (a)(1) 
and (a)(2) of this section, the owner or operator shall implement, to 
the extent reasonably available, measures to prevent or minimize excess 
emissions. For purposes of this paragraph (a)(3), the term ``excess 
emissions'' means emissions in excess of those that would have occurred 
if there were no start-up, shutdown, or malfunction and the owner or 
operator complied with the relevant provisions of this subpart. The 
measures to be taken shall be identified in the applicable start-up, 
shutdown, and malfunction plan, and may include, but are not limited 
to, air pollution control technologies, recovery technologies, work 
practices, pollution prevention, monitoring, and/or changes in the 
manner of operation of the affected facility. Back-up control devices 
are not required, but may be used if available.
    (b) Start-up, shutdown, and malfunction plan. The owner or operator 
of an affected facility shall develop and implement a written start-up, 
shutdown, and malfunction plan as specified in 40 CFR 63.6(e)(3) and 
table 2A of this subpart. This plan shall describe, in detail, 
procedures for operating and maintaining the affected facility during 
periods of start-up, shutdown, and malfunction and a program for 
corrective action for malfunctioning process and air pollution control 
equipment used to comply with this subpart. A provision for ceasing to 
collect, during a start-up, shutdown, or malfunction, monitoring data 
that would otherwise be required by the provisions of this subpart may 
be included in the start-up, shutdown, and malfunction plan only if the 
owner or operator has demonstrated to the Administrator that the 
monitoring system would be damaged or destroyed if it were not shut 
down during the start-up, shutdown, or malfunction. The affected 
facility shall keep the start-up, shutdown, and malfunction plan on-
site.
    (1) Records of start-up, shutdown, and malfunction. The owner or 
operator shall keep the records specified in paragraphs (b)(1)(i) and 
(b)(1)(ii) of this section.
    (i) Records of the occurrence and duration of each start-up, 
shutdown, and malfunction of operation of process equipment or control 
devices or recovery devices or continuous monitoring systems used to 
comply with this subpart during which excess emissions (as defined in 
paragraph (a)(3) of this section) occur.
    (ii) For each start-up, shutdown, or malfunction during which 
excess emissions (as defined in paragraph (a)(3) of this section) 
occur, records reflecting whether the procedures specified in the 
affected facility's start-up, shutdown, and malfunction plan were 
followed, and documentation of actions taken that are not consistent 
with the plan. For example, if a start-up, shutdown, and malfunction 
plan includes procedures for routing a control device to a backup 
control device, records shall be kept of whether the plan was followed. 
These records may take the form of a ``checklist,'' or other form of 
recordkeeping that confirms conformance with the start-up shutdown, and 
malfunction plan for the event.
    (2) Reports of start-up, shutdown, and malfunction. For the 
purposes of this subpart, the start-up, shutdown, and malfunction 
reports shall be submitted on the same schedule as the semiannual 
reports required under Sec. 60.784(d) of this subpart. Said reports 
shall include the information specified in paragraphs (b)(1)(i) and 
(b)(1)(ii)of this section and shall contain the name, title, and 
signature of the owner or operator or other responsible official who is 
certifying its accuracy.
    (b) Alternative means of emission limitation. If, in the judgment 
of the Administrator, an alternative means of emission limitation will 
achieve a reduction in VOC emissions at least equivalent to the 
reduction in VOC achieved under any design, equipment, work practice, 
or operational standards in this subpart, the Administrator will 
publish a notice permitting the use of the alternative means for 
purposes of compliance with that requirement.
    (1) The notice may condition the permission on requirements related 
to the operation and maintenance of the alternative means.

[[Page 68049]]

    (2) Any notice under paragraph (b) of this section shall be 
published only after public notice and an opportunity for a hearing.
    (3) Any person seeking permission to use an alternative means of 
compliance under this section shall collect, verify, and submit to the 
Administrator information showing that the alternative means achieves 
equivalent emission reductions.
    (c) Permit. Each owner or operator of an affected facility subject 
to this subpart shall obtain a permit under 40 CFR part 70 or part 71 
from the appropriate permitting authority. If EPA has approved a State 
operating permit program under 40 CFR part 71, the permit shall be 
obtained from the State authority. If the State operating permit 
program has not been approved, the owner or operator shall apply to the 
EPA regional office pursuant to 40 CFR part 70.


Sec. 60.788  [Reserved]


Sec. 60.789  Relationship to other regulations.

    (a) The owner or operator who is subject to the provisions of this 
section shall include in the Notification of Compliance Status a 
statement specifying the options being used to comply with the 
provisions of this section.
    (b) Relationship to benzene waste. After the compliance dates 
specified in Sec. 60.770 of this subpart, the owner or operator of a 
Group 1 or Group 2 wastewater stream that is also subject to the 
provisions of 40 CFR part 61, subpart FF is required to comply with the 
provisions of both this subpart and 40 CFR part 61, subpart FF. 
Alternatively, the owner or operator may elect to comply with the 
provisions of paragraphs (b)(1) and (b)(2) of this section, which shall 
constitute compliance with the provisions of 40 CFR part 61, subpart 
FF.
    (1) Comply with the provisions of this subpart; and
    (2) For any Group 2 wastewater stream or organic stream whose 
benzene emissions are subject to control through the use of one or more 
treatment processes or waste management units under the provisions of 
40 CFR part 61, subpart FF on or after September 12, 1994, comply with 
the requirements of this subpart for Group 1 wastewater streams.
    (c) Relationship to RCRA. After the compliance dates specified in 
Sec. 60.770 of this subpart, the owner or operator of any Group 1 or 
Group 2 wastewater stream that is also subject to provisions in 40 CFR 
parts 260 and 272 shall comply with the requirements of either 
paragraph (c)(1) or (c)(2) of this section.
    (1) For each Group 1 or Group 2 wastewater stream, the owner or 
operator shall comply with the more stringent control requirements 
(e.g., waste management units, numerical treatment standards, etc.) and 
the more stringent testing, monitoring, recordkeeping, and reporting 
requirements that overlap between the provisions of this subpart and 
the provisions of 40 CFR parts 260 through 272. The owner or operator 
shall keep a record of the information used to determine which 
requirements were the most stringent and shall submit this information 
if requested by the Administrator; or
    (2) The owner or operator shall submit, no later than four months 
before the applicable compliance date specified in Sec. 60.770 of this 
subpart, a request for a case-by-case determination of requirements. 
The request shall include the information specified in paragraphs 
(c)(2)(i) and (c)(2)(ii) of this section.
    (i) Identification of the wastewater streams that are subject to 
this subpart and to the provisions in 40 CFR parts 260 through 272, 
determination of the Group 1/Group 2 status of those streams using the 
provisions specified in this subpart, determination of whether or not 
those streams are listed or exhibit a characteristic as specified in 40 
CFR part 261, and determination of whether the waste management unit is 
subject to permitting under 40 CFR part 270.
    (ii) Identification of the specific control requirements (e.g., 
waste management units, numerical treatment standards, etc.) and 
testing, monitoring, recordkeeping, and reporting requirements that 
overlap between the provisions of this subpart and the provisions of 40 
CFR parts 260 through 272.
    (d) Overlap with the Vinyl Chloride NESHAP. After the compliance 
dates specified in Sec. 60.770 of this subpart, the owner or operator 
of a Group 1 and Group 2 wastewater stream that is also subject to the 
provisions of 40 CFR part 61 subpart F shall comply with the provisions 
of either paragraph (d)(1) or (d)(2) of this section.
    (1) The owner or operator shall comply with the provisions of both 
this subpart and 40 CFR part 61 subpart F or
    (2) The owner or operator may submit, no later than four months 
before the applicable compliance date specified in Sec. 60.770 of this 
subpart, information demonstrating how compliance with 40 CFR Part 61, 
subpart F, will also ensure compliance with this subpart. The 
information shall include a description of the testing, monitoring, 
reporting, and recordkeeping that will be performed.
    (e) Overlap with the HON. After the compliance dates specified in 
Sec. 60.770 of this subpart, the owner or operator of any Group 1 or 
Group 2 process wastewater stream that is also subject to and 
controlled according to the provisions in 40 CFR, subpart G shall 
comply with either 40 CFR, subpart G or this subpart.
    (f) Overlap with other regulations for monitoring, recordkeeping, 
or reporting with respect to combustion devices, recovery devices, or 
recapture devices. After compliance dates specified in Sec. 60.770 of 
this subpart, if any combustion device, recovery device, or recapture 
device subject to this subpart is also subject to monitoring, 
recordkeeping, and reporting requirements in 40 CFR part 264, subpart 
AA or CC, or is subject to monitoring and recordkeeping requirements in 
40 CFR part 265, subpart AA or CC and other owner or operator complies 
with the periodic reporting requirements under 40 CFR part 264, subpart 
AA or CC that would apply to the device if the facility had final-
permitted status, the owner or operator may elect to comply with the 
monitoring, recordkeeping, and reporting requirements of this subpart, 
or with the monitoring, recordkeeping, and reporting requirements in 40 
CFR parts 264 and/or 265, as described in this paragraph (f), which 
shall constitute compliance with the monitoring, recordkeeping, and 
reporting requirements of this subpart.

    3. Part 60 is amended by adding appendix J to read as follows:

Appendix J to Part 60--How to Determine Henry's Law Constants, Fm 
Values, Fr Values, and Fe Values for Organic Compounds

    1. Use of Appendix and General Information. This appendix has 
four sections. Section 2 contains the procedures for determining 
Henry's law constants, fraction measured (Fm) values, fraction 
removed values (Fr), and fraction emitted (Fe) values for an 
individual chemical. Section 3 describes how to locate certain 
resources. Section 4 contains five tables and thirteen forms.
    1.1 You should use this appendix if you need to:
    1. Determine whether a chemical has a Henry's law constant at 
25 deg. C that is less than 0.1 y/x atmosphere per mole fraction 
(see section 2.1).
    2. Determine a fraction measured (Fm) value for a chemical (see 
section 2.2).

[[Page 68068]]

    3. Subtract the concentration of a chemical from a Method 25D 
concentration (see section 2.3).
    4. Determine the fraction removed (Fr) value for a chemical that 
has a Henry's law constant at 25 deg. C that is greater than or 
equal to 0.1 y/x atmosphere per mole fraction (see section 2.4).
    5. Determine the fraction emitted (Fe) value for a chemical that 
has a Henry's law constant at 25 deg. C that is greater than or 
equal to 0.1 y/x atmosphere per mole fraction (see section 2.5).
    6. Calculate a Henry's law constant at a specific temperature 
using a Henry's law constant at a different temperature for the same 
chemical (see section 2.6).
    1.2 This appendix requires documentation for some procedures. 
The referencing subpart, i.e., the rule to which you are complying, 
may require additional recordkeeping and may specify records 
concerning this appendix that are to be included in reports.
    1.3 When the term ``WATER8'' is used in this appendix, the term 
``WATER8, or updates to WATER8'' must be used for the purposes of 
this appendix. When the term ``CHEM9'' is used in this appendix, the 
term ``CHEM9, or updates to CHEM9'' must be used for the purposes of 
this appendix. When the terms ``waste'' or ``wastewater'' are used 
in this appendix, the term ``waste or wastewater, as applicable to 
the referencing subpart'' must be used for the purposes of this 
appendix. When the terms ``Henry's law constant'' or ``Henry's law 
constants'' are used in this appendix, the terms ``Henry's law 
constant(s) with units of atmosphere per mole fraction'' must be 
used for the purposes of this subpart.
    2. Procedures.
    2.1  How to determine whether a chemical has a Henry's law 
constant at 25 deg. C that is less than 0.1 y/x. You must use one of 
the following to determine whether a chemical has a Henry's law 
constant that is less than 0.1 y/x atmosphere per mole fraction.
2.1.1  Use Table 1. The chemicals listed in Table 1 have a Henry's 
law constant at 25 deg. C that is less than 0.1 y/x atmosphere per 
mole fraction.
2.1.2  Use CHEM9 or WATER8. Use CHEM9 or WATER8 to determine the 
Henry's law constant at 25 deg. C. You must know compound 
properties, such as solubility in water and vapor pressure, and the 
structure of the compound to estimate a Henry's law constant using 
CHEM9 or WATER8.
2.1.3  Determine experimentally. The Henry's law constant may be 
measured by several laboratory techniques. These techniques can be 
categorized as either two phase closed systems techniques or open 
system techniques.
2.1.3.1  Two phase closed systems. For two phase closed system 
techniques, the volume of each phase and two concentration 
measurements are needed. The concentration measurements are: (1) 
concentration in one of the phases, and (2) either the concentration 
in the other phase or the total concentration in both phases. Use 
Form 1 to calculate the Henry's law constant for two phase closed 
systems.
2.1.3.2  Open systems. For open systems, gas is passed through a 
liquid volume containing the compound. The Henry's law constant is 
calculated from the rate of stripping of the compound from the 
water. Use Form 2 to calculate the Henry's law constant for open 
systems.
2.1.4  Calculate a Henry's law constant at 25 deg. C from a Henry's 
law constant at a different temperature for the same chemical. Use 
the procedures specified in section 2.6 to calculate a Henry's law 
constant at 25 deg. C from a Henry's law constant at a different 
temperature for the same chemical.
2.2.  How to determine a Fm value for a chemical. Fm means compound-
specific fraction measured factor, and it has the units of mass 
measured by Method 25D divided by the total mass in the wastewater. 
You must use one of the following to determine the Fm value for a 
chemical.
    2.2.1  Use Table 1 or Table 2. To determine the Fm value for a 
chemical with a Henry's law constant at 25 deg. C that is less than 
0.1 y/x atmosphere per mole fraction, use the Fm value listed for 
the chemical in Table 1. To determine the Fm value for a chemical 
with a Henry's law constant at 25 deg. C that is greater than or 
equal to 0.1 y/x, use the Fm value listed for the chemical in Table 
2.

    Note to section 2.2.1: Table 1 and Table 2 include Fm values for 
Method 25D and for Method 305. Unless otherwise specified in this 
appendix or the referencing subpart, use the Fm values for Method 
25D.

    2.2.2  Use CHEM9. Use CHEM9 to determine an Fm value. You must 
know the structure of the chemical and certain other compound 
properties, e.g., boiling point, Antoine's coefficients, vapor 
pressure, and solubility in water, to estimate an fm value using 
CHEM9. The accuracy of the computer estimation procedure depends on 
the nature of the compound and the quality of the available data. 
The procedure is flexible in that the method can be used with a 
variety of different types of compound data. You must confirm and 
document the compound properties used as inputs for CHEM9 and the 
lack of availability for missing compound properties. In some cases, 
this method is not accurate, especially with missing compound 
properties. Before accepting the estimation values of CHEM9 in these 
cases, you must document the consistency of the predicted values 
with other related experimental data.
    2.2.3  Measure the Fm value. Spike a sample of waste with a 
known amount of the compound of interest. Measure the concentration 
of the sample using Method 25D. The Fm value for the recovery of a 
specific chemical is the ratio of the Method 25D concentration to 
the actual concentration in the waste sample. You must minimize loss 
of organic compounds during sample collection and analysis, and 
maintain sample integrity. An example of acceptable sampling and 
handling procedures are the sampling and handling requirements in 
Method 25D.
    2.2.4  Extrapolating a Method 25D Fm Value from a Method 305 Fm 
value. Method 305 measures the recovered concentration, not the 
actual concentration in the wastewater. The Method 25D correction 
value may be obtained from the Method 305 value and the ratio of the 
Method 25D value to the Method 305 value for that compound. This 
ratio for a compound is independent of the wastewater and may be 
determined once for each compound.
    2.3  How to subtract a chemical from a Method 25D concentration. 
You must follow the procedures specified in sections 2.3.1 through 
2.3.5 to subtract a chemical's concentration from the total 
concentration measured by Method 25D. You may only subtract from the 
total Method 25D concentration compounds for which you have a 
measured concentration (i.e., you must not subtract compounds for 
which test results are below the quantification limit.) If an Fm 
value cannot be determined for a chemical, the concentration of the 
chemical cannot be subtracted from the Method 25D results. You must 
follow the procedures in Form 3 to subtract a chemical from a Method 
25D concentration. Form 4 provides an example.
    2.3.2  Determine the concentration for each chemical in the 
wastewater stream that will be subtracted from the Method 25D 
concentration. The concentration for each chemical must be 
determined using a method and sampling procedure specified in the 
referencing subpart. Methods other than Method 25D and Method 305 
are considered alternative methods for the purposes of this 
appendix.
    2.3.3  Determine the correct Fm value. If an Fm value is needed, 
use the procedures in section 2.2 of this appendix to determine the 
correct Fm value.
    2.3.4  Adjust the concentration of chemicals which may be 
subtracted from the Method 25D concentration. You must multiply the 
concentration of the chemical measured by the alternative method 
(i.e., a method that is not Method 25D or Method 305 and that is 
specified in the referencing subpart) by the Method 25D Fm. The 
product will be the adjusted concentration for that chemical. This 
adjustment must be done for each chemical you subtract from the 
concentration measured by Method 25D.
    2.3.5  Subtract. Subtract the product(s) you calculated from the 
Method 25D concentration.
    2.4  How to determine an Fr value for a chemical with a Henry's 
law constant at 25 deg. C that is greater than or equal to 0.1 y/x. 
Fr means fraction removal value and is unitless. You must use one of 
the following to determine a Fr value.
    2.4.1  Use Table 2. Use the Fr value listed for the chemical in 
Table 2. The chemicals listed in table 2 have a Henry's law constant 
at 25 deg. C that is greater than or equal to 0.1 y/x.
    2.4.2  Use 0.99. Assign an Fr value of 0.99 to any chemical. 
This is the highest Fr value that is assigned to a chemical.
    2.4.3  Use CHEM9. Use CHEM9 to determine the Fr value of a 
chemical. You must know the compound structure and the Henry's law 
constant at 100 deg. C to estimate an Fr value using CHEM9. The 
Henry's law constant at 100 deg. C for a chemical must be determined 
as specified in either section 2.4.3.1, 2.4.3.2, or 2.4.3.3. The 
method used to determine the Henry's law constant at 100 deg. C for 
a chemical must be documented.
    2.4.3.1  Determine Henry's law at 100 deg. C experimentally. The 
Henry's law constant

[[Page 68069]]

may be measured by several laboratory techniques. These techniques 
can be categorized as either two phase closed systems techniques or 
open system techniques.
    2.4.3.1.1  Two phase closed systems. For two phase closed system 
techniques, the volume of each phase and two concentration 
measurements are needed. The concentration measurements are: (1) 
concentration in one of the phases, and (2) either the concentration 
in the other phase or the total concentration in both phases. Use 
Form 1 to calculate the Henry's law constant for two phase closed 
systems.
    2.4.3.1.2  Open systems. For open systems, gas is passed through 
a liquid volume containing the compound. The Henry's law constant is 
calculated from the rate of stripping of the compound from the 
water. Use Form 2 to calculate the Henry's law constant for open 
systems.
    2.4.3.2  Calculate a Henry's law constant at 100 deg. C from a 
Henry's law constant at a different temperature for the same 
chemical. Use the procedures in section 2.6 to calculate a Henry's 
law constant at 100 deg. C from a Henry's law constant at a 
different temperature for the same chemical.
    2.4.3.3  Literature Value. Experimental values of Henry's law 
constants at a 100 deg. C for some chemicals are available in data 
bases or reported in the literature. You must provide the reference 
for and description of any database or literature you used.
    2.5  How to determine an Fe value for a chemical that has a 
Henry's law constant at 25 deg. C that is greater than or equal to 
0.1 y/x. Use the appropriate Fe value as specified in the 
referencing subpart.
    2.5.1  Default Fe values for emissions from both the individual 
drain system and the treatment process. You must measure the 
temperature of the wastewater stream at the point of determination, 
unless another location is specified by the referencing subpart. If 
the temperature of the wastewater stream is less than or equal to 
35 deg. C, you may use the default Fe values listed in either Table 
2 or Table 3. If the temperature of the wastewater stream is greater 
than 35 deg. C, you must use the default Fe values listed in Table 
3.
    2.5.1.1  Use Table 2. To use Table 2, use the default Fe value 
listed for the chemical in Table 2.
    2.5.1.2  Use Table 3. You must either use a default Fe listed in 
Table 3 or use Table 3 to interpolate an Fe value. To use Table 3, 
you must determine the chemical's Henry's law constant at the 
temperature you measured for the wastewater stream. You must find 
this Henry's law constant in the table and select an Fe value 
greater than or equal to the Fe value that corresponds to the 
Henry's law constant.
    2.5.2  Site-specific Fe values for emissions from the individual 
drain system. Use WATER8 and Forms 6 and 7 for each type of waste 
management unit modeled and Forms 8 through 13, as appropriate for 
the different types of waste management units. (Note that this Fe 
value does not include Fe values for the treatment process.)
    2.5.3  Default Fe values for emissions from the biological 
treatment process (Fet). The default Fe values in Table 4 and Table 
5 are Fe values for the biological treatment system (i.e., the 
wastewater treatment plant) and have been assigned the abbreviation 
``Fet.'' You must measure the temperature of the wastewater 
stream(s) treated in the biological treatment system at the inlet to 
the biological treatment system (e.g., at the bar screen). If the 
temperature of the wastewater stream(s) is less than or equal to 
35 deg. C, you must use either Table 4 or Table 5 to determine the 
Fet value. If the temperature of the wastewater stream is greater 
than 35 deg. C, you must use Table 5 to determine the Fet value.
    2.5.3.1  Use Table 4. To use Table 4, use the default Fet value 
listed for the chemical in Table 4.
    2.5.3.2  Use Table 5. To use Table 5, you must either use a 
default Fet listed in Table 5 or use Table 5 to interpolate an Fet 
value. You must determine the chemical's Henry's law constant at the 
temperature you measured for the wastewater stream. You must find 
this Henry's law constant in the table and select an Fet value 
greater than or equal to the Fet value that corresponds to the 
Henry's law constant.
    2.6  How to calculate a Henry's law constant from a Henry's law 
constant at a different temperature for the same chemical. Use 
WATER8 and Form 5 to estimate a Henry's law constant from a Henry's 
law constant at a different temperature for the same chemical.
    3. Location of resources.
    3.1  Where to find information on CHEM9 and WATER8.

Definitions of Terms

    Area of openings at unit (cm\2\) The area that can vent 
headspace gas or permit outside air to enter the collection system. 
This area is generally less than or equal to the area of the drop 
pipe opening.
    Area of surface (cm\2\) (sump) The area of the surface exposed 
to the wind or to the headspace in a sump. This area generally 
corresponds to the physical area of the sump exposed surface 
horizontal cross-section.
    Assume equilibrium in unit, =1 If condition are present in the 
unit such that equilibrium is expected (agitated surface, sealed 
waterfall, splash loading, low gas and liquid flow, or other 
factors) enter a 1 as a computer flag.
    Cover An enclosure that prevents the exchange of ambient air and 
the headspace air. If there are openings in the cover, then air may 
be exchanged with the headspace air. The openings in the cover are 
specified as area of openings at unit.
    Covered, then enter 1 The input value is a computer program flag 
that specifies that the unit is sealed and outside wind will not 
blow across the surface of the liquid in the unit. If the unit is 
covered, this does not indicate that the surface of the liquid is 
not exposed to headspace gas.
    Depth of liquid in sump (cm) The depth in centimeters from the 
top of the liquid surface in the sump to the base of the sump. The 
depth is always positive.
    Depth of water level (cm) (J trap) The depth in centimeters from 
the top of the liquid surface in the water seal to the base of the 
water seal. This depth is always positive and would correspond to 
the wet distance on a dip-stick. This variable may be used for 
periodically active hubs.
    Description of unit This is a general description that 
identifies the unit that is being specified. Examples can include 
``Tank A45'', ``Drain E-17'', ``Sewer WW4'', or other description. 
This description will appear on some of the reports.
    Displacement in oscillation (cm) (J trap) Distance of surface 
level fluctuation in the J trap. The value of the displacement is 
used in an air emission model to estimate air exchange.
    Distance to next unit (cm) The distance of the run of the 
underflow conduit that connects the unit to the next unit 
downstream.
    Distance to trap liquid surface (cm) (J trap) The depth in 
centimeters from the top of the open hub top to the liquid surface 
within the J trap. The depth is always positive and would correspond 
to the dry distance on a dip-stick.
    Drop length to conduit (cm) The length in centimeters from the 
top of the hub in the drop pipe to the typical liquid surface in the 
underflow conduit. The length is always positive.
    Drop length to conduit (cm) (J trap) The length in centimeters 
from the water seal in the J trap to the typical liquid surface in 
the underflow conduit. The length is always positive.
    Flow entrance depth under surface (cm) The length between the 
surface of the liquid in the sump and the base of the inlet conduit. 
This length is always positive and represents the effective depth of 
flow for the mass transfer model.
    Fractional approach to equilibrium The fraction of equilibrium 
between the liquid and the headspace in the lift station unit. The 
lift station model uses this value as an input parameter because 
analysis of laboratory data indicated that the vent gas in an 
enclosed unit with a waterfall was approximately 50% of the 
equilibrium value. For water falling in a more open unit, consider 
using the waterfall unit instead of the lift station model.
    Headspace The headspace is the air over the wastewater in the 
enclosed underflow conduit.
    Municipal waste in conduit=1 The input value is a computer 
program flag which identifies which mass transfer model is used for 
the calculations. A value of zero is the default value and the mass 
transfer is calculated using the trench model correlation derived 
from Owens. A value of 1 would calculate mass transfer through the 
Parkhurst-Pomeroy correlation for municipal sewers. Additional 
options for mass transfer options may be added in the future.
    Open surface=1 The input value is a computer program flag which 
indicates that the surface of the unit receiving the waste is open 
to the atmosphere. Zero is the default value (closed unit). Many of 
the collection system units have this option for flexibility. This 
flag does not refer to the underflow conduit, only to the units. The 
flow of headspace in the drop pipe will be of less importance if the 
drop pipe connects to a unit that is open.
    Open surface=1 (J trap) The input value is a computer program 
flag which indicates that the surface of the unit receiving the 
waste is open to the atmosphere. Zero is the default value, and it 
is considered very unusual to use an open J trap for discharge into 
a unit with an exposed surface.
    Open surface=1 (sump) The input value is a computer program flag 
which indicates that the surface of the unit receiving the waste is 
open to the atmosphere. Zero is the default value, and a value of 1 
indicates that there are potential air emissions from wind blowing 
across the surface. Grates and perforated covers are considered 
characteristic of an open surface.
    Oscillation cycle time (min) The cycle time or period of the 
water level rise and drop in an open water trap. Variations in the 
internal headspace pressure will cause water level oscillations.
    Radius of drop pipe (cm) The radius in centimeters in the drop 
pipe that connects the hub to the unit. There is no water seal on 
the drop pipe (see J trap).
    Radius of drop pipe (cm) (J trap) The radius in centimeters in 
the drop pipe forming a water seal in the J trap. The drop pipe 
connects the hub to the water seal in the J trap.

[[Page 68113]]

    Radius of underflow conduit (cm) One half the diameter of a 
circular exiting pipe that connects the unit to the next unit 
downstream. This pipe is considered closed and not exposed to leaks 
and air exchange with the environment during the run of the pipe. If 
the conduit is not closed, consider the trench model.
    Rise The difference in elevation in an underflow conduit that 
connects collection system units.
    Run The path in an underflow conduit that connects collection 
system units.
    Slope of underflow conduit The ratio of the rise to the run in 
the underflow conduit. The slope is always positive and measured 
from downstream to upstream in each run.
    Subsurface entrance=1 This input value is a computer program 
flag which indicates that the headspace is blocked from flowing into 
or out of the upstream underflow conduits. A value of zero indicates 
that there is no headspace blockage.
    Subsurface exit=1 This input value is a computer program flag 
which indicates that the headspace is blocked from flowing into or 
out of the underflow conduit downstream. A value of zero indicates 
that there is no headspace blockage.
    Total water added at the unit (l/s) This is an optional 
specification of the total amount of water added to the collection 
system at the unit. This specification is only used if water is 
added to the specified wastewater streams at the unit. This optional 
specification could be used if the total wastewater flow at the unit 
differed from the sum of the flows of the wastes upstream of the 
unit.
    Underflow conduit The exiting pipe or trench that connects the 
unit to the next unit downstream. This conduit may be (1) closed and 
not exposed to leaks and air exchange with the environment during 
the run of the pipe or (2) exposed to leaks and air exchange with 
the environment.
    Underflow Temperature (C) The entrance temperature of the liquid 
into the unit. The temperature of the waste stream is specified 
separately.
    Velocity air at opening (ft/min) The velocity of flow into the 
unit at the specified unit openings (see area of openings at unit). 
This value is only used if a special flag is set. (See Form 6 
general specifications 22. Specified line vent rates, =1)
    Waste added to system at unit number The input information of 
waste streams into the collection system units is accomplished by 
specifying the waste number. The waste number refers to a data base 
element that includes the drop distance into the hub, the flow rate, 
the temperature, concentrations, the oil content and other 
information.
    Waterfall drop height (cm) The distance from the top of the 
waterfall to the tailwater surface level (unit liquid underflow 
level) . This value is always positive.
    Waterfall: Open surface=1 The input value is a computer program 
flag which indicates that the waterfall is open to the atmosphere. 
Zero is the default value (waterfall is enclosed).
    Waterfall: tailwater depth (m) The depth of flow in the 
underflow conduit under the waterfall.
    Waterfall width at surface (m) The width of the waterfall across 
the at the upper liquid level. The flow rate is used with the width 
to estimate the thickness of the falling water film.
