ENVIRONMENTAL PROTECTION AGENCY

40 CFR Part 63

[EPA-R01-OAR-2020-0007; FRL-10498-01-R1]


Approval of the Clean Air Act, Section 112(l), Authority for 
Hazardous Air Pollutants: Air Emissions Standards for Halogenated 
Solvent Cleaning Machines; State of Rhode Island Department of 
Environmental Management

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

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

SUMMARY: The EPA is proposing to grant the Rhode Island Department of 
Environmental Management (RI DEM) the authority to implement and 
enforce the amended Rhode Island Code of Regulations, Control of 
Emissions from Organic Solvent Cleaning (Organic Solvent Cleaning 
Rule), and the General Definitions Regulation (General Definitions 
Rule) in place of the National Emission Standard for Halogenated 
Solvent Cleaning (Halogenated Solvent NESHAP) as a partial rule 
substitution as it applies to organic solvent cleaning machines in 
Rhode Island. Upon approval, RI DEM's amended Organic Solvent Cleaning 
Rule and General Definitions Rule would apply to all sources that 
otherwise would be regulated by the Halogenated Solvent NESHAP, except 
for continuous web cleaning machines, for which the Halogenated Solvent 
NESHAP would continue to apply. The EPA has reviewed RI DEM's request 
and has preliminarily determined that the State's amended Organic 
Solvent Cleaning Rule and General Definitions Rule satisfy the 
requirements necessary for approval. Thus, the EPA is proposing to 
approve the request. This approval would make RI DEM's amended Organic 
Solvent Cleaning Rule and General Definitions Rule federally 
enforceable. This action is being taken under the Clean Air Act (CAA).

I. Background and Purpose

    Under CAA section 112(l), the 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 for hazardous air pollutants (HAPs). The Federal 
regulations governing the 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 the EPA's approval to 
substitute a state rule for the applicable Federal rule (e.g., the 
National Emission Standards for Hazardous Air Pollutants (NESHAP)). 
Upon approval by the 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.
    The EPA promulgated the National Emissions Standards for 
Halogenated Solvent Cleaning (``Halogenated Solvent NESHAP'') on 
December 2, 1994. See 40 CFR part 63, subpart T. The EPA promulgated 
several amendments to the Halogenated Solvent NESHAP, with the latest 
amendments promulgated on May 3, 2007. See 72 FR 25138.
    On June 18, 2010, the EPA approved the Rhode Island Air Pollution 
Control Regulation No. 36, currently codified in Title 250 Department 
of Environmental Management, Chapter 120 Air Resources, Subchapter 05 
Air Pollution Control, Part 36 Control of Emissions from Organic 
Solvent Cleaning (Organic Solvent Cleaning Rule), and Rhode Island Air 
Pollution Control General Definitions Regulation, currently codified in 
Title 250 Department of Environmental Management, Chapter 120 Air 
Resources, Subchapter 05 Air Pollution Control, Part 0 General 
Definitions Regulation (General Definitions Rule), as a partial rule 
substitution for the Halogenated Solvent NESHAP, applicable to all 
sources in Rhode Island, except for continuous web cleaning 
machines,\1\ for which the Halogenated Solvent NESHAP continues to 
apply. See 75 FR 34647.
---------------------------------------------------------------------------

    \1\ The regulatory text promulgated in 40 CFR 63.99(a)(40)(ii) 
on June 10, 2010 specifies that the EPA's approval applies to area 
sources. However, Rhode Island did not request that the rule 
substitution be limited to area sources. In addition, nothing in the 
June 10, 2010 Federal Register preamble describes the rule 
substitution as being limited to area sources. We believe the rule 
substitution was intended to apply to both major and area sources 
and that the term area source is erroneously included in the 
regulatory text in Sec.  63.99(a)(40)(ii). We therefore propose to 
remove the reference to area sources currently in 40 CFR 
63.99(a)(40)(ii) by this rulemaking.
---------------------------------------------------------------------------

    Under 40 CFR 63.91(e)(2), within 90 days of any state amendment, 
repeal, or revision of any state rule approved as an alternative to a 
Federal requirement, the state must provide the EPA with a copy of the 
revised authorities and request approval of the revised rule. In a 
letter dated June 30, 2022, RI DEM requested approval of its amended 
rules pertaining to organic solvent cleaning in Rhode Island. 
Specifically, RI DEM requested approval of its amended rules in Title 
250 Department of Environmental Management, Chapter 120 Air Resources, 
Subchapter 05 Air Pollution Control, Part 36 Control of Emissions from 
Organic Solvent Cleaning, effective June 13, 2022, excluding the 
provisions in Parts 36.2, 36.5.A.28, 36.6.D, and 36.17,\2\ and in Title 
250 Department of Environmental Management, Chapter 120 Air Resources, 
Subchapter 05 Air Pollution Control, Part 0 General Definitions Rule, 
effective January 4, 2022, excluding the provisions in Part 0.2.\3\ In 
this Federal Register document, the EPA is proposing to approve the 
amended Organic Solvent Cleaning Rule and General Definitions Rule 
under the rule substitution criteria in 40 CFR 63.93.
---------------------------------------------------------------------------

    \2\ The excluded provisions at Parts 36.A.5.28, 36.6.D, and 
36.17 apply to industrial solvent cleaning not regulated by the 
Halogenated Solvent NESHAP. We are not proposing to approve these 
provisions.
    \3\ The excluded provisions at Parts 36.2 and 0.2 state that the 
State's regulation shall be liberally construed to permit RI DEM to 
effectuate the purposes of state laws, goals and policies. We are 
not proposing to approve these provisions.
---------------------------------------------------------------------------

    Rhode Island's Part 36 Organic Solvent Cleaning Rule was also 
submitted as a State Implementation Plan (SIP) revision for purposes of 
meeting reasonable available control technology (RACT) requirements for 
volatile organic compounds (VOCs). The EPA will take action on that 
submittal in a separate document.

II. What requirements must a state rule meet to substitute for a 
section 112 rule?

    A state must first demonstrate that it has satisfied the ``up-
front'' 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 the EPA's 
regulations at 40 CFR 63.91(d). These criteria require, among other 
things, that the state has demonstrated that its program contains 
adequate authorities to assure compliance with each applicable Federal 
requirement, adequate resources for implementation, and an expeditious 
compliance schedule. Under 40 CFR

[[Page 78623]]

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 October 1, 2001, the EPA promulgated full approval 
of RI DEM's operating permits program. See 66 FR 49839. Accordingly, RI 
DEM 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 the 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 the EPA may approve, a partial 
delegation of the EPA's authorities. CAA 112(l)(1). To obtain a partial 
rule substitution, the state's submittal must meet the otherwise 
applicable requirements in 40 CFR 63.93 and be separable from the 
portions of the program that the state is not seeking rule substitution 
for. See 64 FR 1889, January 12, 1999.
    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 the 
EPA determines equivalency for state alternative NESHAP requirements is 
provided in the preamble to the EPA's proposed subpart E amendments on 
January 12, 1999. See 64 FR 1908, January 12, 1999.

III. What material changes did Rhode Island make to its organic solvent 
cleaning rule and general definitions rule?

    Effective as of June 13, 2022,\4\ RI DEM amended Part 36 Control of 
Emissions from Organic Solvent Cleaning (amended Organic Solvent 
Cleaning Rule) and effective as of January 4, 2022, RI DEM amended Part 
0 General Definitions Regulation (amended General Definitions Rule). 
The new State regulations differ in several ways from the regulations 
we last approved in 2010. See 75 FR 34647.
---------------------------------------------------------------------------

    \4\ Since the EPA's 2010 approval, Rhode Island amended Part 36 
on January 9, 2017, and then subsequently on January 13, 2019 and 
June 13, 2022.
---------------------------------------------------------------------------

    In 2016, the State of Rhode Island revised its Administrative 
Procedures Act to require that every state regulation be rewritten into 
the new Rhode Island Code of Regulations format. In order to meet this 
requirement, Part 0 General Definitions Rule and Part 36 Organic 
Solvent Cleaning Rule were revised consistent with the required format. 
Changes to the format included renumbering and lettering the 
provisions, moving the general provisions about purpose, authority, and 
severability from the end of the regulation to the beginning, and 
eliminating the table of contents. In addition, Rhode Island added an 
incorporated materials section to adopt and incorporate the Federal 
regulations cited within the rule. These revisions are not substantive, 
and they continue the State program we had previously approved, with 
the exceptions noted below. Our prior approval notice contains a 
detailed discussion of the differences between Rhode Island's Organic 
Solvent Cleaning Rule and the Halogenated Solvent NESHAP. See 75 FR 
34647, June 18, 2010.
    In addition to the recodification to the new format, Rhode Island 
also made several substantive changes to the Part 36 Organic Solvent 
Cleaning Rule. The following discussion summarizes the material changes 
to Rhode Island's amended Organic Solvent Cleaning Rule. A detailed 
side by side comparison table of Rhode Island's amended Organic Solvent 
Cleaning Rule compared to the Halogenated Solvent NESHAP is included in 
the docket identified in the ADDRESSES section of this Federal Register 
document See Enclosure 1 of Rhode Island's June 30, 2022 submission.
    Rhode Island's amended Organic Solvent Cleaning Rule added an 
exemption from requirements for cold cleaning machines with an internal 
volume of 1 liter or less and not using halogenated HAP solvents as 
defined. See Rhode Island's Part 36.6.C. Because Rhode Island regulates 
cold cleaning machines with an internal volume of 1 liter or less if 
using halogenated HAP solvents as does the Halogenated Solvent NESHAP, 
Rhode Island's amended Organic Solvent Cleaning Rule is no less 
stringent than the Halogenated Solvent NESHAP. See 40 CFR 63.460(a).
    Rhode Island's amended Organic Solvent Cleaning Rule changed the 
requirement for batch vapor machines without a solvent air interface to 
determine compliance with the three-month rolling emission limit on the 
15th of every month. The Halogenated Solvent NESHAP requires these 
machines to determine compliance with the three-month rolling emission 
limit on the 1st of every month. Because the State's rule and the 
NESHAP require the same frequency of determining compliance (i.e., once 
every month), Rhode Island's amended Organic Solvent Cleaning rule is 
not less stringent than the Halogenated Solvent NESHAP. See Rhode 
Island's Part 36.12.A.3 and 40 CFR 63.464 and 63.465(c).
    Rhode Island's Organic Solvent Cleaning Rule includes solvent vapor 
pressure limits for certain cold cleaning operations. Rhode Island's 
amended Organic Solvent Cleaning Rule clarified the provisions for cold 
cleaning machines excluded from the solvent vapor pressure limits. The 
Halogenated Solvent NESHAP does not set vapor pressure limits for 
solvents. Because Rhode Island's rule amended Organic Solvent Cleaning 
rule imposes limits beyond what the NESHAP requires, it is not less 
stringent than the Halogenated Solvent NESHAP. See Rhode Island's Part 
36.9.G.
    Rhode Island's Organic Solvent Cleaning Rule includes a monthly 
halogenated HAP solvent emission limit for all organic solvent cleaning 
operations, calculated on a 12-month rolling average basis. Rhode 
Island's amended Organic Solvent Cleaning Rule added explicit 
compliance dates for sources complying with the monthly halogenated HAP 
solvent emission limit. See Rhode Island's Parts 36.8.Q and 36.7.B. 
Rhode Island's monthly halogenated HAP solvent emission limit 
compliance dates are consistent with the Halogenated Solvent NESHAP. 
See 40 CFR 63.460(i).
    Rhode Island removed the specific dates for approval of 
alternatives for machines installed before November 29, 1993 because 
those dates have passed. Rhode Island's amended Organic Solvent 
Cleaning Rule requires alternatives to be submitted and approved by EPA 
and RI DEM before startup of the machine. Rhode Island's amended 
Organic Solvent Cleaning Rule is equivalent to the Halogenated Solvent 
NESHAP. See Rhode Island's Parts 36.9.C.2, 36.10.F.5, 36.10.G.3, 
36.11.H.3, and 36.11.G.4 and 40 CFR 63.469.

[[Page 78624]]

    Rhode Island removed the provision requiring requests to be 
submitted by December 1, 1996, for exemptions from automated parts 
handling for machines installed before November 29, 1993, because the 
deadline has passed for sources to request an exemption from parts 
handling for machines installed before November 29, 1993. Rhode 
Island's amended Organic Solvent Cleaning Rule requires requests for 
exemption from parts handling to be submitted 30 days before startup of 
the solvent cleaning machine. The Halogenated Solvent NESHAP does not 
have an analogous requirement for sources to request using the 
alternative emission limitation as an alternative to the control 
technology standards. Both the Halogenated Solvent NESHAP and Rhode 
Island's rule require sources complying with the alternative emission 
standard to report solvent emissions averages. Because Rhode Island's 
amended Organic Solvent Cleaning Rule imposes this request requirement 
that the NESHAP does not require, it is not less stringent than and is 
consistent with the Halogenated Solvent NESHAP. See Rhode Island's Part 
36.16 and 40 CFR 63.464.
    Rhode Island removed initial notification and compliance 
notification reporting dates for sources installed before November 29, 
1993, because those reporting deadlines have passed. Rhode Island's 
amended Organic Solvent Cleaning Rule requires sources to submit an 
initial notification 120 days before startup and a compliance 
notification report 60 days after startup. The Halogenated Solvent 
NESHAP requires the initial notification for new sources to be 
submitted as soon as practicable before construction or reconstruction 
is commenced and requires the initial statement of compliance report to 
be submitted no later than 150 days after startup. Because RI's amended 
Organic Solvent Cleaning Rule requires a more expeditious notification 
and reporting schedule than the NESHAP, it is not less stringent than 
and is consistent with the Halogenated Solvent NESHAP. See Rhode 
Island's Parts 36.15.1.A and 36.15.2.A and 40 CFR 63.468(b)-(e).
    Rhode Island amended and added definitions in order to be 
consistent with the NESHAP, including definitions for air blanket, 
consumption, contaminants, cover, halogenated HAP solvent, hoist, 
overall control device efficiency, part, soil, solvent/air interface 
area, sump heater, sump heater coils, and vapor cleaning. Because Rhode 
Island's definitions are equivalent to those in the NESHAP, Rhode 
Island's rule is no less stringent than the NESHAP. See Rhode Island's 
Part 36.5 and 40 CFR 63.461.

IV. What is the EPA's evaluation regarding Rhode Island's amended 
organic solvent cleaning rule and general definitions rule?

    After reviewing the request for approval of Rhode Island's amended 
Organic Solvent Cleaning Rule and General Definitions Rule, the EPA 
proposes to find that this request meets all of the requirements 
necessary to qualify for a partial rule substitution approval under CAA 
section 112(l) and 40 CFR 63.93. Specifically, we believe that the 
amended State program generally continues the program we approved in 
2010, with the exceptions described in this document. We thus 
incorporate the findings we made in our 2010 approval notification. See 
75 FR 34650, June 18, 2010. The amendments to the program since then 
are generally non-substantive changes to conform the State's 
regulations to its recently revised Administrative Procedures Act. We 
have scrutinized the several substantive changes as described above and 
find that these do not unfavorably affect the stringency of the State's 
program or its consistency with the NESHAP. We thus propose to find 
that Rhode Island's amended Organic Solvent Cleaning Rule and General 
Definitions Rule meet all the criteria for our approval in 40 CFR 
63.93(b): the State's program is not less stringent than the 
Halogenated Solvent NESHAP as required by each of the criteria set 
forth in 40 CFR 63.93(b)(1)-(2), is consistent with the compliance 
schedule in the NESHAP as required by 40 CFR 63.93(b)(3), and satisfies 
the compliance and enforcement requirements in 40 CFR 63.93(b)(4). We 
make these findings for the State's program as applied to all sources 
in Rhode Island otherwise regulated by the Halogenated Solvent NESHAP, 
except for continuous web cleaning machines for which the Halogenated 
Solvent NESHAP would continue to apply. Therefore, the EPA proposes to 
approve Rhode Island's amended Organic Solvent Cleaning Rule, effective 
as of June 13, 2022, and Rhode Island's General Definitions Rule, 
effective as of January 4, 2022, in lieu of the Halogenated Solvent 
NESHAP, for all sources in Rhode Island, except for continuous web 
cleaning machines.

V. Proposed Action

    EPA is proposing to approve RI DEM's amended rules in Title 250 
Department of Environmental Management, Chapter 120 Air Resources, 
Subchapter 05 Air Pollution Control, Part 36 Control of Emissions from 
Organic Solvent Cleaning, effective as of June 13, 2022, excluding the 
provisions in Parts 36.2, 36.5.A.28, 36.6.D, and 36.17, and in Title 
250 Department of Environmental Management, Chapter 120 Air Resources, 
Subchapter 05 Air Pollution Control, Part 0 General Definitions 
Regulation, effective as of January 4, 2022, excluding the provisions 
in Part 0.2, as a partial rule substitution for the Halogenated Solvent 
NESHAP, for all sources in Rhode Island, except for continuous web 
cleaning machines. EPA is soliciting public comments on the issues 
discussed in this document. These comments will be considered before 
the EPA takes final action. Interested parties may participate in the 
Federal rulemaking procedure by submitting written comments to this 
proposed rule by following the instructions listed in the ADDRESSES 
section of this Federal Register document.

VI. Incorporation by Reference

    In this rule, the EPA is proposing to include in a final EPA rule 
regulatory text that includes incorporation by reference. In accordance 
with requirements of 1 CFR 51.5, the EPA is proposing to incorporate by 
reference Rhode Island's rules in Title 250 Department of Environmental 
Management, Chapter 120 Air Resources, Subchapter 05 Air Pollution 
Control, Part 36 Control of Emissions from Organic Solvent Cleaning, 
effective as of June 13, 2022, excluding the provisions in Parts 36.2, 
36.5.A.28, 36.6.D, 36.17, and in Title 250 Department of Environmental 
Management, Chapter 120 Air Resources, Subchapter 05 Air Pollution 
Control, Part 0 General Definitions Regulation, effective as of January 
4, 2022, excluding the provisions in Part 0.2. The EPA has made, and 
will continue to make, these documents generally available through 
https://www.regulations.gov and at the EPA Region 1 Office (please 
contact the person identified in the FOR FURTHER INFORMATION CONTACT 
section of this preamble for more information).

VII. Statutory and Executive Order Reviews

    Under the CAA, the Administrator has the authority to approve CAA 
section 112(l) submissions that comply with the provisions of the Act 
and applicable Federal regulations. In reviewing section 112(l) 
submissions, the EPA's role is to approve state choices, provided that 
they meet the criteria and objectives of the CAA and of the EPA's 
implementing regulations. Accordingly, this action proposes to

[[Page 78625]]

approve the State's request as meeting Federal requirements and does 
not impose additional requirements beyond those imposed by State law. 
For that reason, this proposed 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).
    In addition, this rule 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. It also 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) because the EPA is proposing to approve the State's request 
as meeting Federal requirements and is not imposing additional 
requirements beyond those imposed by State law. This rule does not have 
Tribal implications as specified by Executive Order 13175 (65 FR 67249, 
November 9, 2000), because the EPA is not proposing to approve the 
submitted rule to apply in Indian country located in the State, and 
because the submitted rule will not impose substantial direct costs on 
Tribal governments or preempt Tribal law.
