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; Rule Clarifications

AGENCY: Environmental Protection Agency (EPA).

ACTION: Final rule; amendments.

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

SUMMARY: On April 22, 1994 and June 6, 1994, the EPA issued 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. This rule is commonly known 
as the Hazardous Organic NESHAP or the HON. In June 1994, petitions for 
review of the April 1994 rule were filed in the U.S. Court of Appeals 
for the District of Columbia Circuit. The petitioners raised over 75 
technical issues and concerns with drafting clarity of the rule. On 
August 26, 1996, the EPA proposed correcting amendments to the rule to 
address the petitioners' issues. Among the proposed amendments were 
proposed revisions that would eliminate the need for filing some 
implementation plans that would otherwise be due December 31, 1996, and 
would allow the filing of requests for compliance extensions up to four 
months before the April 1997 compliance date. Today's action takes 
final action on those proposed amendments.
    These amendments to the rule will not change the basic control 
requirements of the rule or the level of health protection it provides. 
The rule requires new and existing major sources to control emissions 
of hazardous air pollutants (HAP) to the level reflecting application 
of the maximum achievable control technology. Final action on the rest 
of the amendments proposed on August 26, 1996 will be taken in a 
separate Federal Register document at a later date.

EFFECTIVE DATE: December 5, 1996.

INFORMATION CONTACT Section.

B. Background on Rule

    On April 22, 1994 (59 FR 19402) and June 6, 1994 (59 FR 29196), the 
EPA published in the Federal Register the NESHAP for the 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. Since the April 22, 1994 notice, there have been 
several amendments to clarify various aspects of the rule. Readers 
should see the following Federal Register notices for more information: 
September 20, 1994 (59 FR 48175); October 24, 1994 (59 FR 53359); 
October 28, 1994 (59 FR 54131); January 27, 1995 (60 FR 5321); April 
10, 1995 (60 FR 18020); April 10, 1995 (60 FR 18026); December 12, 1995 
(60 FR 63624); February 29, 1996 (61 FR 7716); June 20, 1996 (61 FR 
31435); and August 26, 1996 (61 FR 43698).
    In June 1994, the Chemical Manufacturers Association (CMA) and Dow 
Chemical Company filed petitions for review of the promulgated rule in 
the U.S. Court of Appeals for the District of Columbia Circuit, 
Chemical Manufacturers Association v. EPA, 94-1463 and 94-1464 (D.C. 
Cir.) and Dow Chemical Company v. EPA, 94-1465 (D.C. Cir.). The 
petitioners raised over 75 technical issues on the rule's structure and 
applicability. Issues were raised regarding details of the technical 
requirements, drafting clarity, and structural errors in the drafting 
of certain sections of the rule. On August 26, 1996, the EPA proposed 
clarifying and correcting amendments to subparts F, G, H, and I of Part 
63 to address the issues raised by CMA and Dow on the April 1994 rule.
    In the August 26, 1996 notice, the EPA committed to taking final 
action on some portions of the proposed amendments to the rule as soon 
as possible after the close of the comment period in order to give 
sources as much lead time as possible. The comment period on the August 
26, 1996 proposal ended on September 25, 1996. With today's action, the 
EPA is taking final action on those portions of the proposed amendments 
that would eliminate the need for filing some implementation plans that 
would otherwise be due December 31, 1996, and would allow the filing of 
requests for compliance extensions up to four months before the April 
1997 compliance date.

C. Public Comment on the August 26, 1996 Proposal

    Eighteen comment letters were received on the August 26, 1996 
notice of proposed changes to the rule. All comment letters received 
were from industry representatives and trade associations. All comment 
letters were supportive of the proposed amendments pertaining to the 
requirements for implementation plans and to the deadline for filing of 
compliance extension requests. A few of these comment letters also 
included suggested editorial revisions to further clarify some aspects 
of these proposed amendments. The EPA considered these suggestions and, 
where appropriate, made changes to the proposed amendments.

D. Judicial Review

    Under Section 307(b)(1) of the CAA, judicial review of this final 
action is available only on the filing of a petition

[[Page 64573]]

for review in the U.S. Court of Appeals for the District of Columbia 
Circuit within 60 days of today's publication of this final rule. Under 
Section 307(b)(2) of the CAA, the requirements that are subject to 
today's notice may not be challenged later in civil or criminal 
proceedings brought by the EPA to enforce these requirements.

II. Summary of Comments and Amendments to the Rule

A. Rule Changes To Eliminate the Need for Filing Implementation Plans

1. Rule Changes To Remove Requirement for Filing Implementation Plans
    On August 26, 1996 the EPA proposed to remove the requirement for 
submittal of implementation plans for existing sources' emission points 
that are not included in an emissions average. Under the 1994 final 
rule, owners or operators who have not yet submitted an operating 
permit application with the information specified in Sec. 63.152(e) 
were required to submit by December 31, 1996, an implementation plan 
for all points not included in an emissions average. The proposed 
amendments to the rule to eliminate this requirement specified that 
this information would be provided in an operating permit application 
or as otherwise specified by the permitting authority.
    All comments on the proposed amendments supported the proposal to 
remove the redundant reporting requirement. Commenters also recommended 
that Sec. 63.151(a)(2) should be revised to clarify that new sources 
are required to submit an implementation plan unless an operating 
permit application containing the information specified in 
Sec. 63.152(e) has been submitted. This correction was recommended in 
order to make this paragraph consistent with Sec. 63.151(c) and thereby 
eliminate the potential for misunderstandings. The EPA agrees that the 
suggested correction of Sec. 63.151(a)(2) is appropriate and this 
correction is included in the final amendments to this paragraph. No 
editorial revisions were suggested for any of the other paragraphs 
affected by this change to the rule.
    Although no public comments were received requesting revisions to 
other paragraphs affected by this group of amendments, the EPA has also 
corrected drafting errors in proposed Sec. 63.120(d)(2) and 
Sec. 63.151(c). In today's amendments, in addition to revising 
Sec. 63.120(d)(2) to remove the reference to the Implementation Plan, 
the EPA is revising Sec. 63.120(d)(2) to specify that the monitoring 
plan for storage vessels complying using a control device must be 
submitted as part of the Notification of Compliance Status. The rule 
amendments proposed on August 26, 1996, required that the monitoring 
plan be submitted, but did not specify when the monitoring plan had to 
be submitted. The need to specify a submittal date was inadvertently 
overlooked when the revisions to remove the implementation plan 
requirement were considered. Because the monitoring plan specifies the 
compliance monitoring requirements for storage vessels complying using 
a control device, the EPA considers the Notification of Compliance 
Status to be the most appropriate report for this information. This 
correction also makes paragraph Sec. 63.120(d)(2) consistent with 
paragraph Sec. 63.120(d)(3) which requires that the operating range for 
the monitored parameter be reported in the Notification of Compliance 
Status. The EPA also made minor editorial revisions to Sec. 63.151(c) 
to improve the organization of this paragraph. The specific changes 
made were to remove redundant text in paragraph (c)(1) and to 
redesignate paragraph (c)(1)(i) as (c)(1). Under this reorganized 
structure, paragraph (c)(1)(ii) is no longer reserved.
    The other proposed changes to remove the requirement to file an 
implementation plan are being added to the final rule without change. 
Today's amendments revise all provisions that require filing of 
implementation plans by December 31, 1996. Some provisions in 
Secs. 63.143, 63.146, and 63.147 still refer to the implementation 
plan. These sections are part of the wastewater provisions in subpart G 
which the EPA anticipates will be final no later than December 31, 
1996.
2. Associated Changes to Rule, Sec. 63.100(i)
    In the August notice, the EPA proposed to revise paragraph (i) to 
include provisions to address the assignment of dedicated distillation 
units and clarify that the assignment procedure in this paragraph 
applies to distillation units shared among several processes. Revisions 
were also proposed to paragraph (i) to clarify the wording of the 
requirement to reassess the assignment of the equipment whenever there 
is a change in the use of the equipment.
    Today's amendments include these clarifying changes to 
Sec. 63.100(i). These changes are being made at this time because it is 
not practical to remove the requirement for submittal of implementation 
plans from these provisions without also finalizing these changes. 
Furthermore, there were no adverse or editorial comments on the 
proposed revisions to paragraph (i). Thus, the proposed changes to 
paragraph (i) are being added to the final rule without change.

B. Timing of Compliance Extension Requests

    The April 22, 1994 rule required that requests for compliance 
extensions be submitted one year prior to the otherwise applicable 
compliance date. In the August 26, 1996 Federal Register, the EPA 
proposed to revise this requirement, which is in Sec. 63.151(a)(6)(i), 
to allow submittal of requests up to 120 days prior to the compliance 
date. The EPA also proposed to add a new paragraph (iv) to 
Sec. 63.151(a)(6) that would allow requests during the last 120 days 
before the compliance date if the need arose during that 120 days and 
if the need was due to circumstances beyond the reasonable control of 
the owner or operator. All comments were supportive of these proposed 
amendments and of the rationale for these changes. None of the comments 
included recommendations for editorial changes to clarify these 
provisions. Thus, the proposed amendments are being added to the rule 
without change.
    One commenter did, however, encourage the EPA to refrain from 
taking enforcement actions against applicants during the EPA's review 
of the requested compliance extension. While the rule is silent on this 
issue, the EPA will bear the commenter's concern in mind in reviewing 
such applications. It is generally not the EPA's practice to take 
enforcement action against a source that has timely filed an extension 
request until the request has been acted on negatively.

C. Correction to Sec. 63.106(a)

    In the August notice, the EPA proposed to correct the delegation of 
authority citation in Sec. 63.106(a) to reference Section 112(l), not 
Section 112(d), of the CAA. No comments were received on this proposed 
change. Thus, the proposed change to Sec. 63.106(a) is being added to 
the final rule without change.

III. Administrative Requirements

A. Paperwork Reduction Act

    The Office of Management and Budget (OMB) has approved the 
information collection requirements contained in the rule the 
Provisions of the Paperwork Reduction Act, 44 U.S.C. 3501 et seq. and 
has assigned OMB control number 2060-0282. An Information Collection

[[Page 64574]]

Request (ICR) document was prepared by EPA (ICR No. 1414.02) and a copy 
may be obtained from Sandy Farmer, OPPE Regulatory Information 
Division; U.S. Environmental Protection Agency (2137); 401 M St., S.W.; 
Washington, DC 20460 or by calling (202) 260-2740.
    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 EPA's 
regulations are listed in 40 CFR part 9 and 48 CFR Chapter 15.
    The changes listed in this Rule: Amendments to the NESHAP will have 
no impact on the information collection burden estimates previously 
made. Further, the changes remove redundant reporting requirement, do 
not impose additional ones, and appropriately revises the deadline for 
submitting compliance extension requests for this rule. Consequently, 
the ICR has not been revised for this rule.

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 Hon rule promulgated on April 22, 1994 was considered 
``significant'' under Executive Order 12866, and a regulatory impact 
analysis was prepared. The amendments issued today remove a redundant 
reporting requirement and revise the deadline for submitting compliance 
extension requests to a date more appropriate for this rule. These 
amendments do not add any new control requirements. Therefore, this 
regulatory action is considered ``not significant.''

C. Regulatory Flexibility

    The EPA has determined that it is not necessary to prepare a 
regulatory flexibility analysis in connection with this final rule. The 
EPA has also determined that this rule will not have a significant 
economic impact on a substantial number of small entities. See the 
April 22, 1994 Federal Register (59 FR 19449) for the basis for this 
determination. The changes to the rule remove a reporting requirement 
and provide additional time to request compliance extensions. 
Therefore, the changes do not create a burden for any of the regulated 
entities.

D. Submission to Congress and the General Accounting Office

    Under 5 U.S.C. 801(a)(1)(A), as added by the Small Business 
Regulatory Enforcement Fairness Act of 1996, the EPA submitted a report 
containing this rule 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 the rule in today's 
Federal Register. This rule is not a ``major rule'' as defined by 5 
U.S.C. 804(2).

E. 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. Under Section 205, the EPA must select the most cost-
effective and 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 the action promulgated today 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.

    (i) Except as provided in paragraph (i)(4) of this section, the 
owner or operator shall follow the procedures specified in paragraphs 
(i)(1) through (i)(3) and (i)(5) of this section to determine whether 
the vent(s) from a distillation unit is part of the source to which 
this subpart applies.
    (1) Where a distillation unit is dedicated to a chemical 
manufacturing process unit, the distillation column shall be considered 
part of that chemical manufacturing process unit.

[[Page 64575]]

    (i) If the chemical manufacturing process unit is subject to this 
subpart according to the criteria specified in paragraph (b) of this 
section, then the distillation unit is part of the source to which this 
subpart applies.
    (ii) If the chemical manufacturing process unit is not subject to 
this subpart according to the criteria specified in paragraph (b) of 
this section, then the distillation unit is not part of the source to 
which this subpart applies.
    (2) If a distillation unit is not dedicated to a single chemical 
manufacturing process unit, then the applicability of this subpart and 
subpart G of this part shall be determined according to the provisions 
in paragraphs (i)(2)(i) through (i)(2)(iv) of this section.
    (i) If the greatest input to the distillation unit is from a 
chemical manufacturing process unit located on the same plant site, 
then the distillation unit shall be assigned to that chemical 
manufacturing process unit.
    (ii) If the greatest input to the distillation unit is provided 
from a chemical manufacturing process unit that is not located on the 
same plant site, then the distillation unit shall be assigned to the 
chemical manufacturing process unit located at the same plant site that 
receives the greatest amount of material from the distillation unit.
    (iii) If a distillation unit is shared among chemical manufacturing 
process units so that there is no single predominant use as described 
in paragraphs (i)(2)(i) and (i)(2)(ii) of this section, and at least 
one of those chemical manufacturing process units is subject to this 
subpart, the distillation unit shall be assigned to the chemical 
manufacturing process unit that is subject to this subpart. If more 
than one chemical manufacturing process unit is subject to this 
subpart, the owner or operator may assign the distillation unit to any 
of the chemical manufacturing process units subject to this subpart.
    (iv) If the predominant use of a distillation unit varies from year 
to year, then the applicability of this subpart shall be determined 
based on the utilization that occurred during the year preceding April 
22, 1994. This determination shall be included as part of an operating 
permit application or as otherwise specified by the permitting 
authority.
    (3) If the chemical manufacturing process unit to which the 
distillation unit is assigned is subject to this subpart, then each 
vent from the individual distillation unit shall be considered 
separately to determine whether it is a process vent (as defined in 
Sec. 63.101 of this subpart). Each vent that is a process vent is part 
of the source to which this subpart applies.
    (4) If the distillation unit is part of one of the chemical 
manufacturing process units listed in paragraphs (i)(4)(i) through 
(i)(4)(iii) of this section, then each vent from the individual 
distillation unit shall be considered separately to determine whether 
it is a process vent (as defined in Sec. 63.101 of this subpart). Each 
vent that is a process vent is part of the source to which this subpart 
applies:
    (i) The Aromex unit that produces benzene, toluene, and xylene;
    (ii) The unit that produces hexane; or
    (iii) The unit that produces cyclohexane.
    (5) If a distillation unit that was dedicated to a single chemical 
manufacturing process unit, or that was part of a chemical 
manufacturing unit identified in paragraphs (i)(4)(i) through 
(i)(4)(iii) of this section, begins to serve another chemical 
manufacturing process unit, or if applicability was determined under 
the provisions of paragraphs (i)(2)(i) through (i)(2)(iv) of this 
section and there is a change so that the predominant use may 
reasonably have changed, the owner or operator shall reevaluate the 
applicability of this subpart to the distillation unit.
