National Emission Standards for Hazardous Air Pollutants for
Source Categories: Organic Hazardous Air Pollutants From the Synthetic
Organic Chemical Manufacturing Industry and Other Processes Subject to
the Negotiated Regulation for Equipment Leaks; Correction
AGENCY: Environmental Protection Agency (EPA).
ACTION: Final rule; Correcting amendments.
-----------------------------------------------------------------------
SUMMARY: This action corrects several errors in cross-referencing
provisions and clarifies regulatory text of the ``National Emission
Standards for Hazardous Air Pollutants for Source Categories: Organic
Hazardous Air Pollutants from the Synthetic Organic Chemical
Manufacturing Industry and Other Processes Subject to the Negotiated
Regulation for Equipment Leaks,'' which was issued as a final rule on
April 22, 1994 and June 6, 1994. This rule is commonly known as the
Hazardous Organic NESHAP or the HON.
EFFECTIVE DATE: December 12, 1995.
FOR FURTHER INFORMATION CONTACT: Dr. Janet S. Meyer, Coatings and
Consumer Products Group, Emissions Standards Division (MD-13), U.S.
Environmental Protection Agency, Research Triangle Park, North Carolina
27711, telephone number (919) 541-5254.
SUPPLEMENTARY INFORMATION: On April 22, 1994 (59 FR 19402) and June 6,
1994 (59 FR 29196), the EPA promulgated the
[[Page 63625]]
national emission standards for hazardous air pollutants (NESHAP) for
the synthetic organic chemical manufacturing industry (SOCMI), and for
several other processes subject to the equipment leaks portion of the
rule. These regulations were promulgated as subparts F, G, H, and I in
40 CFR part 63, and are commonly referred to as the Hazardous Organic
NESHAP or the HON. On September 20, 1994, the EPA published in the
Federal Register a notice of corrections to typographical and cross-
referencing errors in subparts F, H, and I of the final regulations.
The notice also included a few editorial changes to clarify the intent
of certain provisions in those subparts. This notice contains
additional corrections to typographical and cross-referencing errors,
as well as additional editorial changes to clarify the intent of
certain provisions in subparts F, G, and H of the final regulations.
Corrections are being made to Sec. 63.100(f)(1) and the definition
of ``batch operation'' in Sec. 63.101 of subpart F to clarify that the
process vent provisions of the rule apply only to continuous vents, and
the definition of batch operation was intended to apply to unit
operations. This correction is necessary to avoid confusion over the
applicability of the process vent control requirements. The definition
of ``batch operation'' is being revised to clarify that the term
``batch operation'' refers to a unit operation within the chemical
manufacturing process unit rather than to the entire chemical
manufacturing process unit operation. To improve consistency with the
definition of ``unit operation,'' the definition of ``batch operation''
under Sec. 63.101 of subpart F is being revised to cover all
operations, including but not limited to, extraction, drying,
condensation, filtration, absorption, distillation, and reaction. This
same revision is being made to the definition of ``batch operation''
under Sec. 63.111 of subpart G.
Section 63.104(b)(1)(i)(C) is being revised to correct a drafting
error. The restrictive clause ``If monitoring for speciated HAP'' is
being deleted from that paragraph because it was the EPA's intention in
the final rule that under the provisions for monitoring cooling water,
whether a source chooses to monitor for total hazardous air pollutants
(HAP), total volatile organic compounds (VOC), or speciated HAP, the
source is required to monitor for only those HAP that are present in
the process fluid in concentrations greater than 5 percent by weight.
A few revisions are being made to subpart F to improve consistency
in terminology and consistency among the provisions in subparts A, F,
and H. To improve consistency among the subpart A, F, and H provisions,
and to correct an error in cross-referencing subpart A,
Sec. 63.100(k)(3) of subpart F is being revised to cross-reference the
compliance extension provisions in Sec. 63.182(a)(6) of subpart H and
Sec. 63.6(i) of subpart A which indicates that sources granted
extensions as provided in subparts A and F are not required to meet the
schedule requirements under subpart H. Additionally, Sec. 63.102(c)(1)
is being revised to correct errors in cross-referencing 40 CFR parts 70
and 71, and Sec. 63.105(a) is being revised to correct an error in
cross-referencing subpart G.
A few corrections are being made to subpart G to improve
consistency in terminology. The term ``vapor pressure'' in table 10,
which is not defined in the HON provisions, is being changed to
``maximum true vapor pressure,'' which is the defined term in the HON
provisions. The definition of ``hard-piping'' is being changed to make
it consistent with an earlier revision to the definition of this term
in subpart H. The definition of the term ``rack-weighted average
partial pressure'' is being changed to clarify that the mole fraction
of the compound is used in calculating the individual HAP maximum true
vapor pressure, and to clarify the definition of the term Gi.
Footnote ``d'' for tables 14b and 15b, and footnote ``e'' for table 16
are being corrected to be consistent with the reporting requirements
specified in those tables.
Various sections in subpart G are being revised to correct drafting
errors in the usage of terms and in cross-referencing. Several
typographical errors in Figure 7, table 6, the definition of
``incinerator'' in Sec. 63.111, and in Secs. 63.144, 63.145, and 63.152
are being corrected. Various cross-referencing errors in table 15a,
table 15b, the definition of ``average flow rate'' in Sec. 63.111, and
in Secs. 63.138, 63.147, 63.150, and 63.175 are being corrected.
Changes are being made to Sec. 63.150 (k) and (k)(1) to correct a
drafting error. The rule should have referred to ``operating permit
authority'' instead of the ``Administrator.'' As discussed in the April
22, 1994 Federal Register, the decision on the hazard/risk evaluation
is to be made by the State or local permit authority, not by the EPA.
The reference to Sec. 63.6(i)(6) of subpart A in
Sec. 63.151(a)(6)(ii) is being revised to reflect the general
provisions as issued in the final rule (59 FR 12408). The reference
made to Sec. 63.6 of subpart A in Sec. 63.151(a)(6)(ii) of the final
HON rule had reflected an earlier draft of the general provisions. This
same cross-reference correction is being made to Sec. 63.182(a)(6)(ii)
of subpart H. Section 63.182(d)(2)(vii) is being corrected to cross-
reference both Sec. 63.173(a) and (b). Nitrobenzene is being added to
table 9 because nitrobenzene was inadvertently not included in table 9
of the version of the HON sent to the Federal Register for printing.
Corrections are being made to several sections in subpart G to
clarify the intent of the provisions. The ``knowledge of the
wastewater'' option for determining average volatile organic hazardous
air pollutant (VOHAP) concentration is being amended to clarify that
water concentrations of HAP must be multiplied by the appropriate
fm factors from table 34 to obtain the volatile HAP fraction. The
drafting in Sec. 63.148(j) is being corrected to clarify the
relationship between those requirements and the reporting requirements
of Secs. 63.152(c) and 63.182(b).
The Implementation Plan requirements in Sec. 63.151(a)(2) and
Sec. 63.151 (c) are being corrected to clarify that for existing
sources, the information required in the implementation plan need not
be submitted earlier than 12 months prior to the compliance date for
sources not using emissions averaging or 18 months prior to the
compliance date for sources using emissions averaging. This
clarification is necessary to make the regulation consistent with the
EPA's intent to allow 18 or 24 months for preparation of the required
information. Due to a drafting error, the final rule could be
interpreted to require earlier submittal of this information for any
source required to submit an operating permit application before these
dates. The intent of Sec. 63.151(c)(1) is to avoid duplicative
submissions of implementation plan information, not to require
submission of such information earlier than 12 or 18 months prior to
the compliance date.
By promulgating these technical corrections directly as a final
rule, the EPA is foregoing an opportunity for public comment on a
notice of proposed rulemaking. Section 553(b) of title 5 of the United
States Code and Section 307(b) of the Clean Air Act permit an agency to
forego notice and comment when ``the agency for good cause finds (and
incorporates the finding and a brief statement of reasons therefore in
the rules issued) that notice and public procedure thereon are
impracticable, unnecessary, or contrary to the public interest.'' The
EPA finds that notice and comment regarding these minor technical
corrections are unnecessary due to their noncontroversial nature and
because they do not substantively
[[Page 63626]]
change the requirements of the HON. The EPA finds that this constitutes
good cause under 5 U.S.C. 553(b) for a determination that the issuance
of a notice of proposed rulemaking is unncessary.

Pollutants From the Synthetic Organic Chemical Manufacturing
Industry for Process Vents, Storage Vessels, Transfer Operations,
and Wastewater
7. Section 63.111 is amended by revising the definitions of
``average flow rate,'' ``batch operation,'' ``hard-piping,''
``incinerator,'' ``mass flow rate,'' and ``rack-weighted average
partial pressure'' to read as follows:
Sec. 63.111 Definitions.
* * * * *
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).
Batch operation means a noncontinuous operation in which a discrete
quantity or batch of feed is charged into a unit operation within a
chemical manufacturing process unit and distilled or reacted at one
time. Batch operation includes noncontinuous operations in which the
equipment is fed intermittently or discontinuously. Addition of raw
material and withdrawal of product do not occur simultaneously in a
batch operation. After each batch operation, the equipment is generally
emptied before a fresh batch is started.
* * * * *
Hard-piping means pipe or tubing that is manufactured and properly
installed using good engineering judgment and standards such as
American National Standards Institute (ANSI) B31-3.
Incinerator means an enclosed combustion device that is used for
destroying organic compounds. Auxiliary fuel may be used to heat waste
gas to combustion temperatures. Any energy recovery section present is
not physically formed into one manufactured or assembled unit with the
combustion section; rather, the energy recovery section is a separate
section following the combustion section and the two are joined by
ducts or connections carrying flue gas. The above energy recovery
section limitation does not apply to an energy recovery section used
solely to preheat the incoming vent stream or combustion air.
* * * * *
Mass flow rate, as used in the wastewater provisions, means the
rate at which the mass of a constituent in a wastewater stream flows
past a point, determined by multiplying the average concentration of
that constituent in the wastewater stream by the average flow rate
(annual average volumetric flow rate) and density of the wastewater
stream, as determined according to the procedures specified in
Secs. 63.144 (e)(2) and (e)(3).
* * * * *
Rack-weighted average partial pressure means the throughput
weighted average of the average maximum true vapor pressure of liquids
containing organic HAP transferred at a transfer rack. The rack-
weighted average partial pressure shall be calculated using the
equation below:
Where:
[[Page 63627]]
P = Rack-weighted average partial pressure, kilopascals.

Sec. 63.144 Process wastewater provisions--test methods and procedures
for determining applicability and Group 1/Group 2 determinations.
* * * * *
(b) * * *
(3) * * *. If the water concentration of an individual HAP present
in the wastewater is used to develop a total VOHAP average
concentration or average VOHAP concentration for that individually
speciated HAP, it shall be multiplied by the HAP-specific fm
factor in table 34 of this subpart to obtain the volatile portion of
that HAP.
* * * * *
(5) * * *
(i) * * *
(B) Total VOHAP concentration (stream) can be determined by summing
the VOHAP concentrations of all individually speciated organic HAP in

(D) If the wastewater stream has a steady flow rate throughout the
year, the total VOHAP average concentration for HAP listed on table 9
of this subpart of the wastewater stream shall be calculated by
averaging the values calculated in paragraph (b)(5)(i)(B) for the
individual samples:
[GRAPHIC][TIFF OMITTED]TR12DE95.003
Where:
Cstream,avg = Total VOHAP average concentration for HAP listed on
