[CT058-7217a; A-1-FRL-6886-5]


Approval and Promulgation of Air Quality Implementation Plans; 
Connecticut; Changes to Various VOC Regulations

AGENCY: Environmental Protection Agency (EPA).

ACTION: Direct final rule.

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

SUMMARY: EPA is approving several revisions to the Connecticut (CT) 
State Implementation Plan (SIP). The revisions being approved consist 
of changes to various volatile organic compound (VOC) regulations that 
are currently in the CT SIP. These changes include: revisions to the 
definition of VOC; revisions to the gasoline loading regulation; 
revisions to the metal cleaning regulation; revisions to the 
miscellaneous metal parts and products coating regulation; and 
revisions to CT's ``reasonably available control technology (RACT) for 
volatile organic compounds'' regulation. Additionally, EPA is approving 
CT's negative declarations for the synthetic organic chemical 
manufacturing industry (SOCMI) distillation and reactor vessel source 
categories for which EPA issued control technique guideline documents 
(CTGs).
    The intended effect of this action is to approve these revisions to 
the SIP in accordance with sections 110 and 182(b)(2) of the Clean Air 
Act (CAA).

DATES: This direct final rule is effective on December 18, 2000 without 
further notice, unless EPA receives relevant adverse comment by 
November 20, 2000. If relevant adverse comment is received, EPA will 
publish a timely withdrawal of the direct final rule in the Federal 
Register and inform the public that the rule will not take effect.

ADDRESSES: Comments may be mailed to David Conroy, Unit Manager, Air 
Quality Planning, Office of Ecosystem Protection (mail code CAQ), U.S.

regulations?
    I. What does ``direct final rulemaking'' mean?

A. What Action Is EPA Taking?

    EPA is approving State Implementation Plan (SIP) revisions 
submitted by the State of Connecticut (CT). This action revises various 
volatile organic compound (VOC) regulations that are currently in the 
CT SIP. EPA is fully approving the following sections of the 
regulations of the State of Connecticut as changes to CT's SIP: (1) 
revisions to the definition of VOC, section 22a-174-1(97); (2) 
revisions to the gasoline loading regulation, section 22a-174-20(b); 
(3) revisions to the metal cleaning regulation, section 22a-174-20(l); 
(4) revisions to the miscellaneous metal parts and products coating 
regulation, section 22a-174-20(s); and (5) revisions to CT's reasonably 
available control technology (RACT) for VOC regulation, section 22a-
174-32.
    In addition to the regulatory changes, EPA is also approving 
negative declarations submitted by CT for two post-1990 CTG categories. 
Specifically, EPA is approving CT's negative declarations for the 
synthetic organic chemical manufacturing industry (SOCMI) distillation 
and reactor vessel source categories for which EPA issued CTG documents 
in 1993. Section 182(b)(2)(A) of the Clean Air Act (CAA) requires 
states with ozone nonattainment areas to revise their SIPs to require 
RACT at facilities in each industrial category covered by a CTG that is 
issued by the Administrator between November 1990 and the date of 
attainment. Through the negative declaration, CT is asserting that 
there are no sources within the State that would be subject to a rule 
for these source categories. EPA is approving this negative declaration 
submittal as meeting the section 182(b)(2)(A) RACT requirements for 
these two source categories. However, if evidence is submitted by 
November 20, 2000 that there are existing sources within CT that, for 
purposes of meeting the RACT requirements, would be subject to a rule 
for these categories, if developed, such comments would be considered 
adverse and EPA would withdraw its approval action on the negative 
declarations.
    Additionally, in order to meet the requirements of section 
182(b)(2)(A), CT revised section 22a-174-32 to apply to facilities 
subject to the three other final CTGs issued by EPA since 1990, i.e., 
the wood furniture, shipbuilding and repair, and aerospace coating 
CTGs. The revised section 22a-174-32 explicitly applies to wood 
furniture manufacturing and aerospace manufacturing and rework 
facilities. And, although there is no explicit applicability provision 
for shipbuilding facilities, section 22a-174-32 was revised to apply 
now to all major stationary sources, which is consistent with the 
applicability of the final shipbuilding CTG, as explained further 
below.

B. What Air Pollutants Are Reduced by the Changes to Connecticut's 
Regulations?

    The changes to CT's regulations reduce emissions of volatile 
organic compounds, or VOCs. Volatile organic compounds are certain 
types of hydrocarbons that are precursors to the type of air pollution 
known as ground level ozone, the main ingredient of smog. Ground-level 
ozone is formed by a chemical reaction between VOCs and oxides of 
nitrogen ( NO<INF>X</INF>) in the presence of sunlight. Therefore, the 
changes to CT's regulations will help reduce ground level ozone.

C. Who Is Affected by Today's Action?

    Today's action approves changes to category-specific regulations 
that affect a variety of VOC-emitting industrial facilities. Section 
22a-174-20(b) applies to gasoline and volatile organic liquid loading 
facilities. Section 22a-174-20(l) applies to facilities that clean or 
prepare metal surfaces. Section 22a-174-20(s)

[[Page 62621]]

applies to facilities that paint and coat certain kinds of metal parts 
and products.
    Additionally, section 22a-174-32 is a general VOC RACT regulation 
that applies to all VOC emitting processes that are not already 
regulated by other VOC control regulations in the CT SIP. Today's 
action approves changes to the applicability of the earlier section 
22a-174-32 requirements in order to include emissions from processes 
previously unregulated under the SIP such as: coating or painting wood 
products, coating or painting aerospace products, painting or 
refinishing commercial ships, storing volatile organic liquids, 
producing batch chemicals or pharmaceuticals, producing VOC-laden 
industrial wastewater and the coating of plastics.

D. Where Do the Changes to the Regulations Apply?

    All of the regulations being considered are applicable across the 
state. However, the applicability of section 22a-174-32 varies 
depending on the location of the VOC-emitting facility. In the area of 
CT designated as serious nonattainment of the ozone standard, the 
regulation applies to facilities with the potential to emit 50 tons of 
VOC or more per year. This area covers all of the State with the 
exception of southwestern CT. In the southwestern portion of CT 
designated as severe nonattainment for ozone, the regulation applies to 
facilities with the potential to emit 25 tons of VOC or more per year.
    Since the shipbuilding CTG applies to facilities with the potential 
to emit 50 tons of VOC or more per year, the applicability of section 
22a-174-32 now covers any shipbuilding sources subject to EPA's CTG. 
Also, consistent with the aerospace and wood furniture manufacturing 
CTGs, section 22a-174-32 specifically applies to facilities with the 
potential to emit 25 tons of VOC or more per year regardless of 
location within the state.

E. When Does Today's Action Take Effect?

    If EPA receives no relevant adverse comments during the 30-day 
public comment period that follows the publication of this notice, EPA 
approval action will be effective 60 days after the date of 
publication.

F. What Is ``Reasonably Available Control Technology,'' or RACT?

    EPA defines RACT as the lowest emission limit that an existing 
polluting source is capable of meeting if it uses pollution control 
equipment and/or material or process changes that are reasonably 
available considering costs and current technology. For many VOC-
emitting industrial categories, EPA has published control technique 
guidelines, or CTGs. CTGs analyze available control technologies and 
recommend emission limitations or technology standards that are 
considered economically feasible.
    The changes being considered today to CT's definition of VOC, 
gasoline loading, and metal cleaning regulations do not affect the CTG-
based RACT standards that are part of the existing regulations in CT. 
The changes being considered for CT's general VOC RACT regulation do 
not change the RACT norms established in the previous version of the 
regulation but do expand the applicability to cover additional 
facilities.
    However, the changes being considered to CT's miscellaneous metal 
parts and products coating regulations define RACT for a new category 
of coatings, i.e., the ``high performance architectural aluminum 
coatings.''
1. What Is EPA's Recommended VOC RACT for Miscellaneous Metal Parts and 
Products Coatings?
    In the CTG for miscellaneous metal parts and products, EPA 
recommended limits for the VOC quantity of various metal coatings. For 
the ``outdoor, harsh exposure, or extreme performance'' coatings, EPA 
recommended a RACT limit of 3.5 pounds of VOC per gallon of coating, 
minus water and exempt solvents, at a cost effectiveness of $6,841 or 
less per ton VOC removed. See EPA document number EPA-450/2-78-015 for 
more details.
2. Do the Changes to Connecticut's VOC RACT for Miscellaneous Metal 
Parts and Products Coatings Meet EPA Guidance?
    The revisions to section 22a-174-20(s) are approvable. These 
revisions include a new definition of ``high performance architectural 
aluminum coating'' and a 6.3 lb VOC per gallon of coating emission 
limit for this type of coating. CT's alternative limit, which 
represents a relaxation from the EPA Control Technique Guideline limit 
of 3.5 lbs VOC per gallon of coating, only applies to a coating 
applicator that emits 3,333 lbs of VOC per month or less (approximately 
20 tons per year) and was an existing source in CT on or before 
November 1, 1994. CT's revisions were proposed in August 1994 and were 
adopted and effective in the State of Connecticut on March 1, 1995.
    At the time of CT's rulemaking, it was documented that compliant 
coatings (3.5 lb VOC per gallon of coating) were not available at that 
add-on controls that were estimated to cost in excess of $15,000 per 
ton of VOC removed were not considered cost-effective. In addition, as 
previously stated, CT's alternative limit only applies to coating 
applicators in use in CT prior to November 1994 and is limited to 20 
tons per year per applicator. There are only two applicators in CT that 
meet these criteria. Therefore, only 40 tons of VOC per year could be 
emitted at the higher limit. Also, new sources of sufficient size would 
trigger a BACT (Best Available Control Technology) or LAER (Lowest 
Achievable Emission Rate) review under CT's new source review program 
for minor and major sources. Furthermore, examination of CT's 1996 
periodic emissions inventory shows that the 40 tons represents only 2 
percent of CT's approximately 1990 tons of VOC emissions per year from 
miscellaneous metal parts and products surface coating operations. 
EPA's Blue Book \1\ allows for deviations from CTG recommendations by 
means of the ``5 percent rule'' (i.e., emission resulting from 
implementation of the state's alternative must be within 5 percent of 
emissions resulting from implementation of EPA's CTG-based model rule).
---------------------------------------------------------------------------

    \1\ ``Issues Relating to VOC Regulation Cutpoints, Deficiencies, 
and Deviations: Clarification to Appendix D of November 24, 1987 
Federal Register'' (May 25, 1988)
---------------------------------------------------------------------------

    Also, section 193 of the Clean Air Act (i.e., the General Savings 
Clause), requires that any regulation in effect before the date of the 
enactment of the Clean Air Act Amendments of 1990 in any non-attainment 
area may only be modified if the modification insures equivalent or 
greater reductions of the same pollutant. Although the changes to pre-
1990 section 22a-174-20(s) represent a potential increase in emissions 
of 40 tons per year, the expanded applicability of section 22a-174-32 
is projected to reduce emissions by more than 40 tons per year. Given 
the VOC reductions resulting from the regulatory changes being acted on 
at this time, CT meets the requirements of the Savings Clause of 
section 193 of the Act.

G. Why Is EPA Promulgating a Full Approval of the Changes to 
Subsections 22a-174-1, 22a-174-20(b), 22a-174-20(l), 22a-174-20(s) and 
Section 22a-174-32?

    The revisions submitted for subsections 22a-174-1, 22a-174-20(b), 
22a-174-20(l), 22a-174-20(s), and the negative declarations for SOCMI 
reactor and distillation processes, are consistent with EPA guidance 
and meet the requirements of the CAA. Therefore,

[[Page 62622]]

EPA is fully approving these changes as revisions to the Connecticut 
SIP.
    Section 22a-174-32 establishes four RACT options. Options (A) and 
(B) of section 22a-174-32(e)(1), in combination with 22a-174-32(e)(2) 
and (e)(3), are methods of achieving RACT by either: (A) operating a 
system to capture and control VOC emissions to reduce VOC emissions by 
at least 85 percent of uncontrolled emissions; or by (B) reducing VOC 
use and emissions by 80 percent through reformulation or process 
changes. Options (C) and (D) are methods of achieving RACT through the 
use of emission reduction credits or an alternative compliance plan.
    Options (A) and (B) define approvable VOC RACT methods. Options (C) 
and (D), however, describe processes by which RACT can be defined, but 
do not define RACT. Connecticut must define explicitly, and have 
approved by EPA, RACT for all of those sources complying with section 
22a-174-32 through Options (C) and (D).
    On October 5, 2000, EPA received a letter from Connecticut 
identifying the facilities for which RACT orders had not yet been 
issued and will be under section 22a-174-32(e)(1)(C) or (D). They are:
1. Keeler and Long/PPG Architectural Finishes
2. Hitchcock Chair Co. Ltd.
3. Carlon Rubber Products
4. Danbury Pharmacal

    Connecticut has not yet submitted any of the necessary single 
source SIP revisions. Connecticut must submit and EPA must approve 
single source SIP revisions for the four sources listed above.
    Although EPA has not received the final single source SIP revisions 
for these four facilities, section 22a-174-32 is fully approvable. On 
November 7, 1996, EPA issued a policy memorandum entitled ``Approval 
Options for Generic RACT Rules Submitted to Meet the non-CTG VOC RACT 
Requirements and Certain NOX RACT Requirements,'' \2\ which applies to 
section 22a-174-32. Generic RACT provisions are those portions of a 
regulation where the emission limit or technology standard is not 
specified in the rule, rather, the determination of a limit is to be 
made on a case-by-case basis. Under the Act, these case-specific RACT 
determinations must be submitted to EPA as revisions to a State's SIP. 
The generic RACT policy allows full approval of a State's non-CTG VOC 
RACT regulation which contains generic provisions if an analysis has 
been completed that demonstrates that the remaining case-specific VOC 
RACT determinations involve a de minimis level of VOC emissions.
---------------------------------------------------------------------------

    \2\ November 7, 1996 memorandum from Sally Shaver, Director, Air 
Quality Strategies and Standards Division, Office of Air Quality 
Planning and Standards, to Air Program Directors, EPA Regional 
Offices.
---------------------------------------------------------------------------

    In the case of Connecticut's section 22a-174-32, analysis has shown 
that the emissions remaining to be covered by the case-specific RACT 
determinations for the four facilities constitute less than 3.5% of 
Connecticut's base year non-CTG VOC RACT emissions. Under the generic 
RACT policy, such emissions can be considered to be de minimis. Given 
this analysis, section 22a-174-32, including the generic provisions, is 
fully approvable.
    It is important to note that approval of this regulation under the 
generic RACT policy does not exempt any remaining miscellaneous sources 
from RACT; rather it is a de minimis deferral of the approval of the 
remaining case-by-case RACT determinations. This means that approval of 
section 22a-174-32 will not relieve the remaining sources of the 
obligation to develop, submit and implement RACT level controls. 
Similarly, approval will not relieve Connecticut of the obligation to 
ensure that all sources within the State comply with the VOC RACT 
requirements of the Act by adopting and implementing emission 
limitations or technology standards. In fact, approval of this 
regulation will serve to reinforce the requirement for the State to 
submit any remaining case-specific RACT determinations. Because section 
22a-174-32 requires that non-CTG VOC RACT determinations be submitted 
to EPA for approval as SIP revisions, approval of the regulation will 
make the requirement to submit remaining non-CTG VOC RACT orders 
enforceable by EPA, as well as by citizens under section 304 of the 
Act.

H. Where to Go for More Information on the Changes to Connecticut's 
Regulations?

    For a more detailed discussion of the changes to Connecticut's VOC 
RACT regulations and EPA's evaluation, you can refer to the technical 
support document, entitled, ``Technical Support Document--Connecticut--
Changes to Various VOC Regulations,'' dated December 15, 1999 and the 
amendment to that document. For copies of the Technical Support 
Document, contact the EPA or the Connecticut Department of 
Environmental Protection at the addresses listed in the addresses 
section of this notice.

I. What Does ``Direct Final Rulemaking'' Mean?

    Essentially, ``direct final rulemaking'' means that the EPA is 
publishing this rule without prior proposal because the Agency views 
this as a noncontroversial amendment and anticipates no adverse 
comments. However, in the proposed rules section of this Federal 
Register publication, EPA is publishing a separate document that will 
serve as the proposal to approve the SIP revision should relevant 
adverse comments be filed. This action will be effective December 18, 
2000 without further notice unless the Agency receives relevant adverse 
comments by November 20, 2000. Please note that if EPA receives adverse 
comment on an amendment, paragraph, or section of this rule and if that 
provision may be severed from the remainder of the rule, EPA may adopt 
as final those provisions of the rule that are not the subject of an 
adverse comment.
    If the EPA receives such comments, then EPA will publish a document 
withdrawing the final rule and informing the public that the rule will 
not take effect. All public comments received will then be addressed in 
a subsequent final rule based on the proposed rule. The EPA will not 
institute a second comment period. Parties interested in commenting 
should do so at this time. If no such comments are received, the public 
is advised that this rule will be effective on December 18, 2000 and no 
further action will be taken on the proposed rule.

II. Final Action

    EPA is approving the SIP revisions concerning CT's changes to 
subsections 22a-174-1(97), 22a-174-20(b), 22a-174-20(l), 22a-174-20(s), 
and section 22a-174-32, as well as the negative declarations for SOCMI 
reactor and distillation processes CTG categories.

III. Administrative Requirements

    Under Executive Order 12866 (58 FR 51735, October 4, 1993), this 
action is not a ``significant regulatory action'' and therefore is not 
subject to review by the Office of Management and Budget. This action 
merely approves state law as meeting Federal requirements and imposes 
no additional requirements beyond those imposed by state law. 
Accordingly, the Administrator certifies that this rule will not have a 
significant economic impact on a substantial number of small entities 
under the Regulatory Flexibility Act (5 U.S.C. 601 et seq.). Because 
this rule approves pre-existing requirements under state law and does 
not impose any additional

[[Page 62623]]

enforceable duty beyond that required by state law, it does not contain 
any unfunded mandate or significantly or uniquely affect small 
governments, as described in the Unfunded Mandates Reform Act of 1995 
(Public Law 104-4). For the same reason, this rule also does not 
significantly or uniquely affect the communities of tribal governments, 
as specified by Executive Order 13084 (63 FR 27655, May 10, 1998). This 
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 (64 FR 43255, August 
10, 1999), because it merely approves a state rule implementing a 
Federal standard, and does not alter the relationship or the 
distribution of power and responsibilities established in the Clean Air 
Act. This rule also is not subject to Executive Order 13045 (62 FR 
19885, April 23, 1997), because it is not economically significant.
    In reviewing SIP submissions, EPA's role is to approve state 
choices, provided that they meet the criteria of the Clean Air Act. In 
this context, in the absence of a prior existing requirement for the 
State to use voluntary consensus standards (VCS), EPA has no authority 
to disapprove a SIP submission for failure to use VCS. It would thus be 
inconsistent with applicable law for EPA, when it reviews a SIP 
submission, to use VCS in place of a SIP submission that otherwise 
satisfies the provisions of the Clean Air Act. Thus, the requirements 
of section 12(d) of the National Technology Transfer and Advancement 
Act of 1995 (15 U.S.C. 272 note) do not apply. As required by section 3 
of Executive Order 12988 (61 FR 4729, February 7, 1996), in issuing 
this rule, EPA has taken the necessary steps to eliminate drafting 
errors and ambiguity, minimize potential litigation, and provide a 
clear legal standard for affected conduct. EPA has complied with 
Executive Order 12630 (53 FR 8859, March 15, 1988) by examining the 
takings implications of the rule in accordance with the ``Attorney 
General's Supplemental Guidelines for the Evaluation of Risk and 
Avoidance of Unanticipated Takings' issued under the executive order. 
This rule does not impose an information collection burden under the 
provisions of the Paperwork Reduction Act of 1995 (44 U.S.C. 3501 et 
seq.).
    The Congressional Review Act, 5 U.S.C. 801 et seq., as added by the 
Small Business Regulatory Enforcement Fairness Act of 1996, generally 
provides that before a rule may take effect, the agency promulgating 
the rule must submit a rule report, which includes a copy of the rule, 
to each House of the Congress and to the Comptroller General of the 
United States. EPA will submit 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 United States prior 
to publication of the rule in the Federal Register. A major rule cannot 
take effect until 60 days after it is published in the Federal 
Register. This action is not a ``major rule'' as defined by 5 U.S.C. 
804(2).
    Under section 307(b)(1) of the Clean Air Act, petitions for 
judicial review of this action must be filed in the United States Court 
of Appeals for the appropriate circuit by December 18, 2000. Interested 
parties should comment in response to the proposed rule rather than 
petition for judicial review, unless the objection arises after the 
comment period allowed for in the proposal. Filing a petition for 
reconsideration by the Administrator of this final rule does not affect 
the finality of this rule for the purposes of judicial review nor does 
it extend the time within which a petition for judicial review may be 
filed, and shall not postpone the effectiveness of such rule or action. 
This action may not be challenged later in proceedings to enforce its 
requirements. (See section 307(b)(2).)
