40 CFR Part 63

[EPA-R01-OAR-2017-0343; A-1-FRL-9972-97-Region 1]

Approval of Section 112(l) Authority for Hazardous Air 
Pollutants; Perchloroethylene Air Emission Standards for Dry Cleaning 
Facilities; State of Vermont

AGENCY: Environmental Protection Agency (EPA).

ACTION: Direct final rule.

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

SUMMARY: The Environmental Protection Agency (EPA) is taking direct 
final action to grant the Vermont Department of Environmental 
Conservation (VT DEC) the authority to implement and enforce, with 
respect to area sources only, the Vermont Perchloroethylene Dry 
Cleaning Rule in place of the National Emissions Standards for 
Hazardous Air Pollutants for Perchloroethylene Dry Cleaning Facilities 
(Dry Cleaning NESHAP). Pursuant to the Clean Air Act (CAA), the VT DEC 
submitted a request for approval to implement and enforce the 
Perchloroethylene Dry Cleaning Rule of the Vermont Air Pollution 
Control Regulations as a partial substitution for the National 
Emissions Standards for Hazardous Air Pollutants for Perchloroethylene 
Dry Cleaning Facilities (Dry Cleaning NESHAP), as it applies to area 
sources. EPA has reviewed this request and has determined that the 
Vermont Perchloroethylene Dry Cleaning Rule satisfies the requirements 
necessary for partial rule substitution. Thus, EPA is hereby granting 
VT DEC's request. This action does not affect the authority of any 
party to implement and enforce the Dry Cleaning NESHAP with respect to 
major source dry cleaners. This approval makes the Vermont 
Perchloroethylene Dry Cleaning Rule federally enforceable in Vermont.

DATES: This direct final rule will be effective June 4, 2018, unless 
EPA receives adverse comments by April 4, 2018. If EPA receives adverse 
comment, EPA will publish a timely withdrawal of the direct final rule 
in the Federal Register informing the public that the rule will not 
take effect. The incorporation by reference of certain publications 
listed in the rule is approved by the Director of the Federal Register 
as of June 4, 2018.

I. General Information

A. Why is the EPA using a direct final rule?

    The EPA is publishing this action without prior proposal because 
the Agency views this as a noncontroversial submittal 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 state rule should 
adverse comments be filed.
    If the EPA receives such comments, then EPA will publish a notice 
withdrawing the direct 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 on the proposed rule. 
All parties interested in commenting on the proposed rule

[[Page 9216]]

should do so at this time. If no such comments are received, the public 
is advised that this rule will be effective on June 4, 2018 and no 
further action will be taken on the proposed rule. For further 
information about commenting on this rule, see the ADDRESSES section of 
this document.

II. Background

    Under CAA section 112(l), EPA may approve state or local rules or 
programs to be implemented and enforced in place of certain otherwise 
applicable Federal rules, emissions standards, or requirements. The 
Federal regulations governing EPA's approval of state and local rules 
or programs under section 112(l) are located at 40 CFR part 63, subpart 
E. See 58 FR 62262 (November 26, 1993), as amended by 65 FR 55810 
(September 14, 2000). Under these regulations, a state air pollution 
control agency has the option to request EPA's approval to substitute a 
state rule for the applicable Federal rule (e.g., the National Emission 
Standards for Hazardous Air Pollutants). Upon approval by EPA, the 
state agency is authorized to implement and enforce its rule in place 
of the Federal rule, and the state rule becomes federally enforceable 
in that state.
    EPA originally promulgated the Dry Cleaning NESHAP on September 22, 
1993. See 58 FR 49354. The Dry Cleaning NESHAP has been amended several 
times and is codified at 40 CFR part 63, subpart M, ``National 
Perchloroethylene Air Emission Standards for Dry Cleaning Facilities.'' 
On May 26, 2017, EPA received VT DEC's request to implement and enforce 
Vermont Air Pollution Control Regulations (VT APCR) section 5-253.11 
Perchloroethylene Dry Cleaning (Vermont Dry Cleaning Rule) in lieu of 
the Dry Cleaning NESHAP as applied to area sources.

III. What requirements must a State rule meet to substitute for a 
Section 112 rule?

    A state must demonstrate that it has satisfied the general 
delegation/approval criteria contained in 40 CFR 63.91(d). The process 
of providing ``up-front approval'' assures that a state has met the 
delegation criteria in Section 112(l)(5) of the CAA as implemented by 
EPA's regulations at 40 CFR 63.91(d). These criteria require, among 
other things, that the state has demonstrated that its NESHAP program 
contains adequate authorities to assure compliance with each applicable 
Federal requirement, adequate resources for implementation, and an 
expeditious compliance schedule. Under 40 CFR 63.91(d)(3), interim or 
final Title V program approval under 40 CFR part 70 satisfies the 
criteria set forth in 40 CFR 63.91(d) for ``up-front approval.'' On 
November 29, 2001, EPA promulgated full approval of VT DEC's operating 
permits program with an effective date of November 30, 2001. See 66 FR 
59535. Accordingly, VT DEC has satisfied the up-front approval criteria 
of 40 CFR 63.91(d).
    Additionally, the regulations governing approval of state 
requirements that substitute for a section 112 rule require EPA to 
evaluate the state's submittal to ensure that it meets the stringency 
and other requirements of 40 CFR 63.93. A rule will be approved if the 
state requirements contain or demonstrate: (1) Applicability criteria 
that are no less stringent than the corresponding Federal rule; (2) 
levels of control and compliance and enforcement measures that result 
in emission reductions from each affected source that are no less 
stringent than would result from the otherwise applicable Federal rule; 
(3) a compliance schedule that requires each affected source to be in 
compliance within a time frame consistent with the deadlines 
established in the otherwise applicable Federal rule; and (4) the 
additional compliance and enforcement measures as specified in 40 CFR 
63.93(b)(4). See 40 CFR 63.93(b).
    A state may also seek, and EPA may approve, a partial delegation of 
the EPA's authorities. See CAA 112(l)(1). To obtain a partial rule 
substitution, the state's submittal must meet the otherwise applicable 
requirements in 40 CFR 63.91 and 63.93, and be separable from the 
portions of the program that the state is not seeking rule substitution 
for. See 64 FR 1889.
    Before we can approve alternative requirements in place of a part 
63 emissions standard, the state must submit to us detailed information 
that demonstrates how the alternative requirements compare with the 
otherwise applicable Federal standard. A detailed discussion of how EPA 
will determine equivalency for state alternative NESHAP requirements is 
provided in the preamble to EPA's proposed Subpart E amendments on 
January 12, 1999. See 64 FR 1908.
    After reviewing VT DEC's partial rule substitution request and 
equivalency demonstration for the Dry Cleaning NESHAP as it applies to 
area sources, EPA has determined this request meets all the 
requirements necessary for approval under CAA section 112(l) and 40 CFR 
63.91 and 63.93.

IV. What if any material differences exist between the Vermont Dry 
Cleaning Rule and the Dry Cleaning NESHAP and what is EPA's evaluation?

    The following discussion explains the major differences between the 
area source requirements in the Vermont Dry

[[Page 9217]]

Cleaning Rule and the area source requirements in the Dry Cleaning 
NESHAP and how EPA evaluated the Vermont Dry Cleaning Rule. A detailed 
side-by-side comparison of these requirements, as well as an 
equivalency narrative, are included in the public docket.

A. What are the differences in applicability?

    The Dry Cleaning NESHAP applies to each dry cleaning facility that 
uses perchloroethylene (PCE), except for coin-operated dry cleaning 
machines. The Dry Cleaning NESHAP exempts existing dry cleaning 
machines from certain requirements if the total PCE consumption of the 
dry cleaning facility is less than 140 gallons per year. See 40 CFR 
63.320(d). The Vermont Dry Cleaning Rule applies to all dry cleaning 
facilities that use PCE at area sources of HAP. The Vermont Dry 
Cleaning Rule has no exemption for coin-operated machines and no 
exemption based on PCE consumption. Under Vermont's rule, major sources 
of Hazardous Air Pollutants (HAP) must continue to comply with the 
Federal Dry Cleaning NESHAP. See VT APCR section 5-253.11(a). 
Consequently, EPA finds that the applicability of the Vermont Dry 
Cleaning Rule is no less stringent than that of the Dry Cleaning 
NESHAP.

B. How does the Vermont Dry Cleaning Rule address the control 
requirements?

    The Dry Cleaning NESHAP requires the owner or operator of each dry 
cleaning system at area sources to equip each dry cleaning machine with 
a refrigerated condenser, except that certain existing dry cleaning 
systems installed between December 9, 1991, and September 22, 1993, may 
alternatively comply by routing the air-perchloroethylene gas-vapor 
stream of each dry cleaning machine through a carbon adsorber. See 40 
CFR 63.322(a). The Dry Cleaning NESHAP requires new area source dry 
cleaning systems installed after December 21, 2005, to equip each dry 
cleaning machine with a refrigerated condenser and a non-vented carbon 
adsorber and to desorb the carbon adsorber in accordance with the 
manufacturer's instruction. See 40 CFR 63.322(o)(2). The Vermont Dry 
Cleaning rule requires all dry cleaning machines to be equipped with a 
refrigerated condenser without exception, and requires dry cleaning 
systems installed after December 21, 2005 to equip each dry cleaning 
machine with a refrigerated condenser and a non-vented carbon adsorber. 
The carbon adsorber must be desorbed in accordance with the 
manufacturer's instruction. The Vermont Dry Cleaning rule does not 
allow a primary carbon adsorber as a method of control. See VT APCR 
section 5-253.11(c)(2) and (4). Both the Vermont Dry Cleaning Rule and 
the Dry Cleaning NESHAP effectively prohibit transfer machines, 
prohibit dry cleaning systems installed after December 21, 2005 in a 
building with a residence, and prohibit any dry cleaning system in a 
building with a residence after December 21, 2020. See VT APCR section 
5-253.11(c)(3), (5)-(6) and 40 CFR 63.322(o)(3)-(5). The Vermont Dry 
Cleaning Rule only allows equivalent control devices approved by the 
Vermont Air Pollution Control Officer and the EPA pursuant to 40 CFR 
63.325. See VT APCR section 5-253.11(c)(2)(ii) and (3). Consequently, 
EPA finds that the Vermont Dry Cleaning control requirements are no 
less stringent than those of the Dry Cleaning NESHAP.

C. How do the monitoring requirements differ?

    The Dry Cleaning NESHAP requires dry cleaning systems at area 
sources to be inspected weekly for perceptible leaks and requires a 
monthly inspection using a halogenated hydrocarbon detector or PCE gas 
analyzer. See 40 CFR 63.322(k) and (o)(1)(i). Instead, the Vermont Dry 
Cleaning Rule requires a weekly inspection for perceptible leaks and a 
weekly inspection using a halogenated hydrocarbon detector or PCE gas 
analyzer. See VT APCR section 5-253.11(e)(1). The Dry Cleaning NESHAP 
requires weekly temperature monitoring to determine if the temperature 
is equal to or less than 45 degrees Fahrenheit, or alternatively 
monitoring of refrigeration system high pressure and low pressure 
during the drying phase. See 40 CFR 63.323(a)(1). The Vermont Dry 
Cleaning Rule requires weekly temperature monitoring of the 
refrigerated condenser and requires the temperature to be maintained at 
less than or equal to 40 degrees Fahrenheit. The Vermont Dry Cleaning 
Rule does not allow refrigeration system high and low pressure 
monitoring as an alternative to temperature monitoring of the 
refrigerated condenser. See VT APCR section 5-253.11(c)(2)(i)(B) and 
(e)(2). Therefore, EPA finds that the Vermont Dry Cleaning Rule 
monitoring requirements are no less stringent than those of the Dry 
Cleaning NESHAP.

D. What are the differences in reporting and recordkeeping?

    The Dry Cleaning NESHAP requires the owner or operator of any new 
dry cleaning facility to submit a notification of compliance status 
within 30 days after startup. See 40 CFR 63.324(b). The Vermont Dry 
Cleaning Rule also requires the owner or operator of any new dry 
cleaning facility to submit a notification of compliance status within 
30 days of commencing operations. See VT APCR section 5-253.11(g)(2). 
Thus, the Vermont Dry Cleaning Rule reporting requirements are no less 
stringent than those of the Dry Cleaning NESHAP.

E. Is the State's submittal separable?

    A state may also seek, and EPA may approve, a partial delegation of 
the EPA's authorities. See CAA 112(l)(1). To obtain a partial rule 
substitution, the state's submittal must meet the otherwise applicable 
requirements in 40 CFR 63.91 and 63.93, and be separable from the 
portions of the program that the state is not seeking rule substitution 
for. See 64 FR 1889. A separable portion of a state rule or program is 
a section(s) of a rule or a portion(s) of a program which can be acted 
upon independently without affecting the overall integrity of the rule 
or program as a whole.
    Here, the state's rule applies to area source dry cleaners, while 
the NESHAP continues to apply to major source dry cleaners. EPA finds 
that there exists a logical and compelling distinction between area and 
major dry cleaning sources. That is, the state rule may independently 
regulate area source dry cleaners separate from major source dry 
cleaners, without affecting the overall integrity of the rule or 
program as a whole. EPA further finds that granting partial delegation 
would not create an overly cumbersome or unworkable scheme. For these 
reasons, EPA concludes that the portion of the NESHAP delegated under 
this partial rule substitution is separable from the remainder of the 
NESHAP. Therefore, partial delegation is appropriate.

F. What is EPA's action regarding the Vermont Dry Cleaning Rule?

    After reviewing VT DEC's request for approval of the Vermont Dry 
Cleaning Rule, EPA has determined that the Vermont Dry Cleaning Rule 
meets all of the requirements necessary for partial rule substitution 
under section 112(l) of the CAA and 40 CFR 63.91 and 63.93. Therefore, 
EPA hereby approves VT DEC's request to implement and enforce VT APCR 
section 5-253.11 (as effective under state law on December 15, 2016), 
in place of the Dry Cleaning NESHAP for area sources in Vermont. As of 
the effective date of this action, the Vermont Dry Cleaning Rule is 
enforceable by EPA and by citizens under the CAA. Although VT DEC has 
primary

[[Page 9218]]

responsibility to implement and enforce the Vermont Dry Cleaning Rule, 
EPA retains the authority to enforce any requirement of the rule upon 
its approval under CAA 112. See CAA section 112(l)(7).

V. Final Action

    EPA is approving the Vermont Air Pollution Control Regulations, 
Chapter 5, Air Pollution Control, section 5-253.11, Perchloroethylene 
Dry Cleaning (as effective under state law on December 15, 2016) as a 
partial rule substitution for the Dry Cleaning NESHAP for area sources 
in Vermont. The Federal Dry Cleaning NESHAP continues to apply to major 
source dry cleaners in Vermont. The applicability of the Federal NESHAP 
to major source dry cleaners is in no way affected by this action.
    This rule will be effective June 4, 2018 without further notice 
unless the Agency receives relevant adverse comments by April 4, 2018.

VI. Incorporation by Reference

    In this rule, the EPA is finalizing regulatory text that includes 
incorporation by reference. In accordance with requirements of 1 CFR 
51.5, the EPA is finalizing the incorporation by reference of Vermont 
Air Pollution Control Regulations, Chapter 5, Air Pollution Control, 
section 5-253.11, Perchloroethylene Dry Cleaning, effective December 
15, 2016. The EPA has made, and will continue to make, these documents 
generally available electronically through http://www.regulations.gov.

VII. Statutory and Executive Order Reviews

    Under the CAA, the Administrator has the authority to approve 
section 112(l) submissions that comply with the provisions of the Act 
and applicable Federal regulations. In reviewing section 112(l) 
submissions, EPA's role is to approve state choices, provided that they 
meet the criteria and objectives of the CAA and of EPA's implementing 
regulations. Accordingly, this action merely approves the State's 
request as meeting Federal requirements and does not impose additional 
requirements beyond those imposed by state law. For that reason, this 
action:
     Is not a significant regulatory action subject to review 
by the Office of Management and Budget under Executive Orders 12866 (58 
FR 51735, October 4, 1993) and 13563 (76 FR 3821, January 21, 2011);
     does not impose an information collection burden under the 
provisions of the Paperwork Reduction Act (44 U.S.C. 3501 et seq.);
     is certified as not having a significant economic impact 
on a substantial number of small entities under the Regulatory 
Flexibility Act (5 U.S.C. 601 et seq.);
     does not contain any unfunded mandate or significantly or 
uniquely affect small governments, as described in the Unfunded 
Mandates Reform Act of 1995 (Pub. L. 104-4);
     does not have Federalism implications as specified in 
Executive Order 13132 (64 FR 43255, August 10, 1999);
     is not an economically significant regulatory action based 
on health or safety risks subject to Executive Order 13045 (62 FR 
19885, April 23, 1997);
     is not a significant regulatory action subject to 
Executive Order 13211 (66 FR 28355, May 22, 2001);
     is not subject to requirements of Section 12(d) of the 
National Technology Transfer and Advancement Act of 1995 (15 U.S.C. 272 
note) because application of those requirements would be inconsistent 
with the CAA; and
     does not provide EPA with the discretionary authority to 
address, as appropriate, disproportionate human health or environmental 
effects, using practicable and legally permissible methods, under 
Executive Order 12898 (59 FR 7629, February 16, 1994).
    In addition, this rule does not have Tribal implications as 
specified by Executive Order 13175 (65 FR 67249, November 9, 2000), 
because the submitted rule is not approved to apply in Indian country 
located in the State, and EPA notes that it will not impose substantial 
direct costs on Tribal governments or preempt Tribal law.
    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). This rule will be effective June 4, 2018.

VIII. Judicial Review

    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 May 4, 2018. Filing a 
petition for reconsideration by the Administrator of this final rule 
does not affect the finality of this action 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).
