Approval and Promulgation of Air Quality Implementation Plans; Oregon; Removal of Perchloroethylene Dry Cleaning Systems Rules

AGENCY:

Environmental Protection Agency (EPA).

ACTION:

Proposed rule.

SUMMARY:

In this action, EPA is proposing to approve a revision to the Oregon State Implementation Plan and repeal rules which are no longer required by the Clean Air Act. The revision consists of the repeal of Oregon's control technology guidelines for perchloroethylene (perc) dry cleaning systems. Perc is a solvent commonly used in dry cleaning, maskant operations, and degreasing operations. In 1996, EPA excluded perc from the Federal definition of volatile organic compounds for the purpose of preparing state implementation plans to attain the national ambient air quality standards for ozone under title I of the Clean Air Act. Emissions from perc dry cleaners continue to be regulated as hazardous air pollutants under the National Emissions Standards for Hazardous Air Pollutants.

SUPPLEMENTARY INFORMATION:

For further information, please see the direct final action, of the same title, which is located in the Rules and Regulations section of this Federal Register. EPA is approving the State's SIP revision as a direct final rule without prior proposal because EPA views this as a noncontroversial SIP revision and anticipates no adverse comments. A detailed rationale for the approval is set forth in the preamble to the direct final rule. If EPA receives no adverse comments, EPA will not take further action on this proposed rule.

If EPA receives adverse comments, EPA will withdraw the direct final rule and it will not take effect. EPA will address all public comments in a subsequent final rule based on this proposed rule. EPA will not institute a second comment period on this action. Any parties interested in commenting on this action should do so at this time. Please note that if we receive 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.
