The EPA is taking direct final action on amendments to the national emission standards for hazardous air pollutants (NESHAP) for asphalt processing and asphalt roofing manufacturing, which were issued on April 29, 2003 under section 112 of the Clean Air Act (CAA). These amendments correct minor errors and add a clarifying exemption inadvertently omitted in the final rule. We are issuing these amendments as a direct final rule, without prior proposal, because we view the revisions as noncontroversial and anticipate no significant adverse comments. However, in the Proposed Rules section of this Federal Register, we are publishing a separate document that will serve as the proposal to amend the national emission standards for asphalt processing and asphalt roofing manufacturing, if significant adverse comments are filed. If we receive any adverse comments on a specific element of the direct final rule, we will publish a timely withdrawal in the Federal Register informing the public which amendments will become effective and which amendments are being withdrawn due to adverse comment. We will address all public comments in a subsequent final rule based on the proposed rule. Any of the distinct amendments in the direct final rule for which we do not receive adverse comment will become effective on the date set out below. We will not institute a second comment period on the direct final rule. Any parties interested in commenting must do so at this time.
