[EPA-ROI-OAR-2010-0207 ; A-1-FRL- ] 

Approval of the Clean Air Act, Section 112(1), Authority for Hazardous Air 

Pollutants : Air Emission Standards for Halogenated Solvent Cleaning Machines: 

State of Rhode Island Department of Environmental Management 

AGENCY: Environmental Protection Agency (EPA). 

ACTION: Proposed rule. 

SUMMARY: Under Clean Air Act section 112(1), 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 . EPA proposes to approve Rhode 

Island Department of Environmental Management's ("RI DEM's") request for approval 

to implement and enforce Air Pollution Control Regulation Number 36, Control of 

Emissions from Organic Solvent Cleaning ("RI Regulation No. 36") and Rhode Island 

Air Pollution Control, General Definitions Regulation ("RI General Definitions Rule"), 

as a partial substitution for the National Emissions Standards for Halogenated Solvent 

Cleaning ("Halogenated Solvent NESHAP") as it applies to organic solvent cleaning 

machines in Rhode Island, except for continuous web cleaning machines. This approval 

would grant RI DEM the authority to implement and enforce RI Regulation No. 36 and 

the RI General Definitions Rule in place of the Halogenated Solvent NESHAP for 

organic solvent cleaning machines and would make the Rhode Island Department of 

Environmental Management's rules referenced above federally enforceable. Continuous 

web cleaning machines would remain subject to the Halogenated Solvent NESHAP .

SUPPLEMENTARY INFORMATION: In the Final Rules Section of this Federal 

Register , EPA is approving the State of Rhode Island's Section 112(1) submittal as a 

direct final rule without prior proposal because the Agency views this as a 

noncontroversial submittal and anticipates no adverse comments. A detailed rationale for 

the approval is set forth in the direct final rule . If no adverse comments are received in 

response to this action rule, no further activity is contemplated . If EPA receives adverse 

comments, the direct final rule will be withdrawn and all public comments received will 

then be addressed in a subsequent final rule based on this proposed rule . EPA will not 

institute a second comment period . Any parties interested in commenting on this action 

should do so at this time. 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.
