National Emission Standards for Hazardous Air Pollutants: Generic 
Maximum Achievable Control Technology (Generic MACT); Process 
Wastewater Provisions

AGENCY: Environmental Protection Agency (EPA).

ACTION: Final rule; amendments.

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

SUMMARY: On June 29, 1999 (64 FR 34854), we promulgated a consolidated 
rulemaking that included standards for four specific source categories 
(i.e., acetal resins (AR), acrylic and modacrylic fiber (AMF), hydrogen 
fluoride (HF) and polycarbonate (PC) production), and general control 
requirements for certain types of emission points for hazardous air 
pollutants (HAP).
    At the time of promulgation of the consolidated rulemaking, we 
deferred taking final action regarding provisions applicable to 
wastewater streams for the AR, AMF, and PC production source categories 
based on a need to propose significant changes to the wastewater 
provisions that were proposed on October 14, 1998 (63 FR 55178). The HF 
production source category does not have wastewater streams. In 
parallel with the promulgated consolidated rulemaking package, we 
published a supplemental notice of proposed rulemaking regarding 
wastewater provisions (64 FR 34950) applicable to wastewater streams 
for the AR, AMF, and PC production source categories and reopened the 
public comment period regarding those proposed wastewater provisions.
    Today's action promulgates wastewater provisions amendments 
applicable to wastewater streams for the AR, AMF, and PC production 
source categories based on our response to comments received on the 
wastewater provisions proposed on June 29, 1999 (64 FR 34950).

EFFECTIVE DATE: November 22, 1999.

ADDRESSES: Docket No. A-97-17 contains supporting information used in 
developing the standards. The docket is located at the U.S. 
Environmental Protection Agency, 401 M Street, SW, Washington, DC 20460 
in room M-1500, Waterside Mall (ground floor), and may be inspected 
from 8:30 a.m. to 5:30 p.m., Monday through Friday, excluding legal 
holidays.

a This table is not intended to be exhaustive, but rather provides a
  guide for readers regarding entities likely to be regulated by this
  action. This table lists the types of entities that the EPA is now
  aware could potentially be regulated by this action. Other types of
  entities not listed in the table could also be regulated. To determine
  whether your facility, company, business, organization, etc., is
  regulated by this action, you should carefully examine the
  applicability criteria in Sec.  63.1104(a)(1), (b)(1), (c)(1), and
  (d)(1) of the rule. If you have questions regarding the applicability
  of this action to a particular entity, consult the person listed in
  the preceding FOR FURTHER INFORMATION CONTACT section.

    Judicial review. Under section 307(b)(1) of the Act, judicial 
review of these final wastewater provision amendments is available only 
by filing a petition for review in the United States Court of Appeals 
for the District of Columbia Circuit by January 21, 2000. Under section 
307(d)(7)(B) of the Act, only an objection to these wastewater 
provisions amendments which was raised with reasonable specificity 
during the period for public comment can be raised during judicial 
review. Moreover, under section 307(b)(2) of the Act, the requirements 
established by today's final action may not be challenged separately in 
any civil or criminal proceeding we bring to enforce these 
requirements.

I. What Is the Background for These Wastewater Provision 
Amendments?

    On June 29, 1999 (64 FR 34854), we promulgated a consolidated 
rulemaking that included generic MACT standards under section 112 of 
the Act for certain small source categories consisting of five or fewer 
sources. At that time, we proposed amendments to the provisions 
applicable to wastewater and certain liquid streams in open systems and 
deferred taking final action on those provisions until now. Today's 
action finalizes these amendments based on comments received on the 
proposed amendments and our response to those comments.

II. Compliance Dates

    The compliance dates for the standards promulgated on June 29, 1999 
(64 FR 34854) for the AR, AMF, and PC production source categories are 
July 1, 2002 for existing sources and upon startup after June 29, 1999 
for new sources. Additional compliance time is not warranted for 
existing sources, and there have not been any new AR, AMF, and PC 
production facilities that would warrant specifying a different 
compliance date for new sources. Therefore, although we deferred action 
on the wastewater provisions for the AR, AMF, and PC production source 
categories, the dates for compliance with the wastewater provisions 
adopted by this action will be the same as for the other provisions we 
previously promulgated on June 29, 1999.

III. Comments Received on the Proposed Wastewater Provisions 
Amendments

    We received no major comments on the wastewater provisions 
amendments proposed on June 29, 1999 (64 FR 34950). We have made 
limited clarifying changes and some editorial changes in response to 
comments received. Clarifying changes include (1) amending 40 CFR part 
63, subpart YY by replacing the term ``chemical manufacturing process 
unit'' and ``CMPU'' with the phrase ``a process unit whose primary 
product is a product produced by a source category subject to this 
subpart''; (2) amending 40 CFR part 63, subpart YY applicability tables 
for process wastewater requirements to reflect that both Group 1 and 
Group 2 wastewater streams are subject to requirements under 
Sec. 63.1106(a); and (3) amending 40 CFR part 63, subpart YY to clarify 
that when a source subject to this subpart is colocated with a 
Synthetic Organic Chemical Manufacturing Industry (SOCMI) source, and a 
single wastewater treatment facility treats similar wastewaters from 
both sources, a certification by the treatment facility that they will 
manage and treat the waste in conformity with the specific control 
requirements set forth in 40 CFR 63.133 through 63.147 will also be 
deemed sufficient to satisfy the certification requirements for the 
generic MACT wastewater provisions.
    A supplementary information memorandum that contains a summary of 
the public comments received on the proposed wastewater provisions 
amendments and our response to those comments may be obtained from the 
docket for this rule, A-97-17 (see Docket).

IV. Summary of Final Wastewater Provisions Amendments

    The final wastewater provisions amendments incorporate and cross-
reference wastewater provisions of the HON for the AR, AMF, and PC 
production source categories. These final amendments respond to 
comments received on the proposed wastewater provisions published on 
October 14, 1998 (63 FR 55178), and the proposed amendments to those 
provisions published on June 29, 1999 (64 FR 34950). In addition, these 
final amendments reflect our original intent regarding ``point of 
determination'' measurements and ``treatment and destruction'' 
requirements for process wastewater, and that requirements for 
maintenance wastewater and liquid streams in open systems be included.
    The final amendments for process wastewater, maintenance 
wastewater, and liquid streams in open systems within the regulated 
process unit directly refer to HON wastewater requirements. For process 
wastewater, you are required to make a group determination for each 
wastewater stream based on flow rate and organic HAP concentration. If 
a process wastewater stream is determined to be Group 1, you must 
comply with specific requirements for waste management units to 
suppress emissions, and requirements to treat the wastewater streams to 
reduce the organic HAP concentration. The suppression requirements in 
the referenced sections of the HON are equivalent in stringency to the 
wastewater requirements that were initially proposed on October 14, 
1998 (63 FR 55178) for most emissions points associated with wastewater 
streams.
    The maintenance wastewater provisions require, for each maintenance 
wastewater stream that contains organic HAP, that you develop and 
follow procedures to manage wastewaters generated during maintenance 
activities so that emissions are minimized. The provisions for liquid 
streams in open systems apply to drain or drain hubs, manholes, lift 
stations, trenches, pipes, oil/water separators, and tanks within the 
regulated process unit, and require that you implement specific 
emission reduction techniques for each type of equipment.

V. Summary of Impacts

    We estimate that the impacts for air emissions will be negligible 
because AR, AMF, and PC production affected sources that will be 
subject to these requirements are already well controlled. Similarly, 
water pollution and solid waste, and increases in energy use resulting 
from the use of control devices will be negligible. Based on

[[Page 63697]]

previous impacts analyses associated with the application of the 
control and recovery devices required under the standards and because 
each of the three subject source categories have only five or fewer 
major sources, we believe that there will be minimal, if any, adverse 
environmental or energy impacts associated with the final amendments.
    Likewise, based on available information, we estimate that the cost 
and economic impacts of the final wastewater provisions amendments for 
the three source categories being regulated will be insignificant or 
minimal. The economic analyses for each of the three source categories 
can be obtained from the docket (see Docket).

VI. Administrative Requirements

A. Paperwork Reduction Act

    The information collection requirements associated with these 
wastewater provisions amendments do not add to the promulgated rule 
information collection requirements. The information collection 
requirements of the promulgated rule for the generic MACT standards 
were submitted for approval to the Office of Management and Budget 
(OMB) under the Paperwork Reduction Act, 44 U.S.C. 3501, et seq. Under 
the promulgated rule, we prepared an Information Collection Request 
(ICR) document (ICR No. 1750.01) and a copy may be obtained from Sandy 
Farmer, OPPE Regulatory Information Division, U.S. Environmental 
Protection Agency (2137), 401 M Street, SW, Washington, DC 20460, or by 
calling (202) 260-2740. We 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 our regulations are listed in 40 CFR part 9 and 48 CFR chapter 15. 
The OMB approved the information collection requirements for the AR, 
AMF, and PC production source categories and assigned the OMB control 
number 2060-0420 to the ICR. This approval expires September 30, 2002.

B. Executive Order 12866

    Under Executive Order 12866 (58 FR 51735, October 4, 1993), we must 
determine whether a 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 result in 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, or 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 final wastewater provisions amendments for AR, AMF, and PC 
production do not constitute a ``significant regulatory action'' as 
defined under Executive Order 12866, and therefore, are not subject to 
review by OMB.

C. Executive Order 13132 (Federalism)

    Executive Order 13132, entitled ``Federalism'' (64 FR 43255, August 
10, 1999), requires EPA to develop an accountable process to ensure 
``meaningful and timely input by State and local officials in the 
development of regulatory policies that have federalism implications.'' 
``Policies that have federalism implications'' is defined in the 
Executive Order to include regulations that have ``substantial direct 
effects on the States, on the relationship between the national 
government and the States, or on the distribution of power and 
responsibilities among the various levels of government.'' Under 
Executive Order 13132, EPA may not issue a regulation that has 
federalism implications, that imposes substantial direct compliance 
costs, and that is not required by statute, unless the Federal 
government provides the funds necessary to pay the direct compliance 
costs incurred by State and local governments, or EPA consults with 
State and local officials early in the process of developing the 
proposed regulation. EPA also may not issue a regulation that has 
federalism implications and that preempts State law unless the Agency 
consults with State and local officials early in the process of 
developing the proposed regulation.
    If EPA complies by consulting, Executive Order 13132 requires EPA 
to provide to the Office of Management and Budget (OMB), in a 
separately identified section of the preamble to the rule, a federalism 
summary impact statement (FSIS). The FSIS must include a description of 
the extent of EPA's prior consultation with State and local officials, 
a summary of the nature of their concerns and the agency's position 
supporting the need to issue the regulation, and a statement of the 
extent to which the concerns of State and local officials have been 
met. Also, when EPA transmits a draft final rule with federalism 
implications to OMB for review pursuant to Executive Order 12866, EPA 
must include a certification from the agency's Federalism Official 
stating that EPA has met the requirements of Executive Order 13132 in a 
meaningful and timely manner.
    This final rule will not have substantial direct effects on the 
States, on the relationship between the national government and the 
States, or on the distribution of power and responsibilities among the 
various levels of government, as specified in Executive Order 13132. 
This rule has minimal direct affects on the 9 plants which are impacted 
by this rule. This rule has even less impacts on States within which 
the plants reside. Thus,the requirements of section 6 of the Executive 
Order do not apply to this rule.

D. Regulatory Flexibility Act/Small Business Regulatory Enforcement 
Fairness Act of 1996

    Under the Regulatory Flexibility Act (RFA) of 1980 (5 U.S.C. 601, 
et seq.), as amended by the Small Business Regulatory Enforcement 
Fairness Act of 1996 (SBREFA), we are required to give special 
consideration to the effect of Federal regulations on small entities 
and to consider regulatory options that might mitigate any such 
impacts.
    Today's action is not subject to the requirements of the RFA as 
modified by SBREFA because it does not impose any regulatory 
requirements on small entities.

E. Unfunded Mandates Reform Act

    Under section 202 of the Unfunded Mandates Reform Act of 1995 
(Unfunded Mandates Act), we 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 1 year. Under section 203, we are required to establish 
a plan for obtaining input from and informing, educating, and advising 
any small governments that may be significantly or uniquely affected by 
the rule. Under section 205 of UMRA, we must identify and consider a 
reasonable number of regulatory alternatives before promulgating a rule 
for which a budgetary impact statement must be prepared. We are 
required to select the

[[Page 63698]]

least burdensome alternative for State, local, and tribal governments 
and the private sector that achieves the objectives of the rule, unless 
we explain why this alternative is not selected or unless the selection 
of this alternative is inconsistent with law.
    Because the promulgated rule and these final amendments to the rule 
do not include a Federal mandate and are estimated to result in 
expenditures less than $100 million in any 1 year by State, local, and 
tribal governments, we have not prepared a budgetary impact statement 
or specifically addressed the selection of the least costly, most cost-
effective, or least burdensome alternative. In addition, because small 
governments would not be significantly or uniquely affected by this 
rule, we are not required to develop a plan with regard to small 
governments. Therefore, the requirements of the UMRA do not apply to 
this action.

F. National Technology Transfer and Advancement Act

    Under section 12(d) of the National Technology Transfer and 
Advancement Act of 1995 (NTTAA), Pub. L. 104-113, section 12(d) (15 
U.S.C. 272 note), we are directed to use voluntary consensus standards 
instead of government-unique standards in our regulatory activities 
unless to do so would be inconsistent with applicable law or otherwise 
impractical. By doing so, the Act is intended to reduce the cost to the 
private and public sectors.
    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. We are required by the NTTAA to provide Congress, 
through OMB, explanations when we decide not to use available and 
applicable voluntary consensus standards.
    As part of a larger effort, we are undertaking a project to cross-
reference existing voluntary consensus standards on testing, sampling, 
and analysis, with current and future EPA test methods. When completed, 
this project will assist us in identifying potentially-applicable 
voluntary consensus standards that can then be evaluated for 
equivalency and applicability in determining compliance with future 
regulations.
    This action does not involve the promulgation of any new technical 
standards. It does, however, cross-reference existing technical 
standards, including government-unique technical standards that have 
been proposed and promulgated under other rulemakings for similar 
source control applicability and compliance determinations, therefore 
section 12(d) does not apply.

G. Executive Order 13045

    Executive Order 13045, entitled Protection of Children from 
Environmental Health Risks and Safety Risks (62 FR 19885, April 23, 
1997), applies to any rule that we determine (1) is economically 
significant as defined under Executive Order 12866, and (2) the 
environmental health or safety risk addressed by the rule has a 
disproportionate effect on children. If the regulatory action meets 
both criteria, we 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 we considered.
    This amendatory action is not subject to Executive Order 13045 
because it does not constitute an economically significant regulatory 
action as defined by Executive Order 12866 and because it does not 
establish an environmental standard intended to mitigate health or 
safety risks.

H. Executive Order 13084

    Under Executive Order 13084, we may not issue a regulation that is 
not required by statute, that significantly or uniquely affects the 
communities of Indian tribal governments, and that imposes substantial 
direct compliance costs on those communities, unless the Federal 
government provides the funds necessary to pay the direct compliance 
cost incurred by the tribal governments, or we consult with those 
governments. If we comply by consulting, we are required to provide to 
OMB, in a separately identified section of the preamble to the rule, a 
description of the extent of our prior consultation with 
representatives of affected tribal governments, a summary of the nature 
of their concerns, and a statement supporting the need to issue the 
regulation. In addition, we are required to develop an effective 
process permitting elected officials and other representatives of 
Indian tribal governments ``to provide meaningful and timely input in 
the development of regulatory policies on matters that significantly or 
uniquely affect their communities.''
    Today's amendments implement requirements specifically set forth by 
Congress in section 112 of the Act without the exercise of any 
discretion by us. Accordingly, the requirements of section 3(b) of 
Executive Order 13084 do not apply to this rule.

I. Congressional Review Act

    Under the Small Business Regulatory Enforcement Fairness Act of 
1996, we submitted a report containing these final amendments and other 
required information to the U.S. Senate, the U.S. House of 
Representatives, and the Comptroller General of the General Accounting 
Office prior to publication of these final amendments in the Federal 
Register. This is not a ``major rule'' as defined by the Small Business 
Regulatory Enforcement Fairness Act.

List of Subjects in 40 CFR Part 63

    Environmental protection, Acetal resins production, Acrylic and 
modacrylic fiber production, Air emissions control, Hazardous air 
pollutants, Polycarbonates production, Process wastewater streams, 
Wastewater.

    Dated: November 15, 1999.
Carol M. Browner,
Administrator.

    For the reasons set out in the preamble, title 40, chapter I, part 
63 of the Code of Federal Regulations is amended as follows:

PART 63--NATIONAL EMISSION STANDARDS FOR HAZARDOUS AIR POLLUTANTS 
FOR SOURCE CATEGORIES

    1. The authority citation for part 63 continues to read as follows:

    Authority: 42 U.S.C. 7401 et seq.

Subpart YY--National Emission Standards for Hazardous Air 
Pollutants for Source Categories: Generic Maximum Achievable 
Control Technology Standards

    2. Section 63.1100 is amended by adding paragraph (g)(5) as 
follows:


Sec. 63.1100  Applicability.

* * * * *
    (g) * * *
    (5) Overlap of subpart YY with other regulations for wastewater. 
(i) After the compliance dates specified in Sec. 63.1102 for an 
affected source subject to this subpart, a wastewater stream that is 
subject to the wastewater requirements of this subpart and the 
wastewater requirements of subparts F, G, and H of this part 
(collectively known as the ``HON'') shall be deemed to be in compliance 
with the requirements of this subpart if it complies with either set of 
requirements. In any instance where a source subject to this subpart is 
colocated with a Synthetic Organic Chemical Manufacturing Industry 
(SOCMI) source, and a single wastewater treatment facility treats both

[[Page 63699]]

Group 1 wastewaters and wastewater residuals from the source subject to 
this subpart and wastewaters from the SOCMI source, a certification by 
the treatment facility that they will manage and treat the waste in 
conformity with the specific control requirements set forth in 40 CFR 
63.133 through 63.147 will also be deemed sufficient to satisfy the 
certification requirements for wastewater treatment under this subpart.
    (ii) After the compliance dates specified in Sec. 63.1102 for an 
affected source subject to this subpart, a wastewater stream that is 
subject to control requirements in the Benzene Waste NESHAP (subpart FF 
of part 61 of this chapter) and this subpart is required to comply with 
both rules.
    3. Section 63.1101 is amended by adding definitions in alphabetical 
order to read as follows:


Sec. 63.1101  Definitions.

* * * * *
    Annual average concentration, as used in the wastewater provisions, 
means the flow-weighted annual average concentration, as determined 
according to the procedures specified in Sec. 63.144(b).
    Annual average flow rate, as used in the wastewater provisions, 
means the annual average flow rate, as determined according to the 
procedures specified in Sec. 63.144(c).
* * * * *
    Group 1 wastewater stream means a process wastewater stream at an 
existing or new source that meets the criteria for Group 1 status in 
Sec. 63.132(c).
    Group 2 wastewater stream means a process wastewater stream that 
does not meet the definition of a Group 1 wastewater stream.
* * * * *
    Maintenance wastewater means wastewater generated by the draining 
of process fluid from components in the process unit, whose primary 
product is a product produced by a source category subject to this 
subpart, into an individual drain system prior to or during maintenance 
activities. Maintenance wastewater can be generated during planned and 
unplanned shutdowns and during periods not associated with a shutdown. 
Examples of activities that can generate maintenance wastewaters 
include descaling of heat exchanger tubing bundles, cleaning of 
distillation column traps, draining of low legs and high point bleeds, 
draining of pumps into an individual drain system, and draining of 
portions of the process unit, whose primary product is a product 
produced by a source category subject to this subpart, for repair.
* * * * *
    Oil-water separator or organic-water separator means a waste 
management unit, generally a tank used to separate oil or organics from 
water. An oil-water or organic-water separator consists of not only the 
separation unit but also the forebay and other separator basins, 
skimmers, weirs, grit chambers, sludge hoppers, and bar screens that 
are located directly after the individual drain system and prior to 
additional waste management units such as an air flotation unit, 
clarifier, or biological treatment unit. Examples of an oil-water or 
organic-water separator include, but are not limited to, an American 
Petroleum Institute separator, parallel-plate interceptor, and 
corrugated-plate interceptor with the associated ancillary equipment.
* * * * *
    Point of determination means each point where process wastewater 
exits the process unit, whose primary product is a product produced by 
a source category subject to this subpart.

    Note to definition for point of determination: The regulation 
allows determination of the characteristics of a wastewater stream 
at the point of determination or downstream of the point of 
determination if corrections are made for changes in flow rate and 
annual average concentration of Table 9 compounds (as defined under 
this subpart) as determined in Sec. 63.144. Such changes include 
losses by air emissions, reduction of annual average concentration 
or changes in flow rate by mixing with other water or wastewater 
streams, and reduction in flow rate or annual average concentration 
by treating or otherwise handling the wastewater stream to remove or 
destroy hazardous air pollutants.

    Process wastewater means wastewater which, during manufacturing or 
processing, comes into direct contact with or results from the 
production or use of any raw material, intermediate product, finished 
product, by-product, or waste product. Examples are product tank 
drawdown or feed tank drawdown, water formed during a chemical reaction 
or used as a reactant, water used to wash impurities from organic 
products or reactants, equipment washes between batches in a batch 
process, water used to cool or quench organic vapor streams through 
direct contact, and condensed steam from jet ejector systems pulling 
vacuum on vessels containing organics.
    Process wastewater stream means a stream that contains process 
wastewater.
* * * * *
    Table 9 compounds means compounds listed in Table 9 of subpart G of 
this part.

    Wastewater is either a process wastewater or a maintenance 
wastewater and means water that:
    (1) Contains either:
    (i) An annual average concentration of Table 9 compounds (as 
defined under this subpart) of at least 5 parts per million by weight 
at the point of determination and has an annual average flow rate of 
0.02 liter per minute or greater, or
    (ii) An annual average concentration of Table 9 compounds (as 
defined under this subpart) of at least 10,000 parts per million by 
weight at the point of determination at any flow rate, and that
    (2) Is discarded from a process unit, whose primary product is a 
product produced by a source category subject to this subpart.
