{"abstract":"This action proposes amendments to the emissions monitoring and compliance provisions contained in Subpart Da--Standards of Performance for Electric Utility Steam Generating Units for Which Construction is Commenced After September 18, 1978, and Subpart Db-- Standards of Performance for Industrial-Commercial-Institutional Steam Generating Units. This action proposes monitoring exemptions and alternative compliance requirements for duct burners used in combined cycle systems. The proposed amendments ensure that all owners or operators of duct burners have appropriate compliance requirements and similar exemptions for their monitoring requirements. In the Rules and Regulations section of this Federal Register, we are making these amendments in a direct final rule, without prior proposal, because we view these revisions as noncontroversial, and we anticipate no significant adverse comments. We have explained our reasons for these amendments in the preamble to the direct final rule. If we receive no significant adverse comments, we will take no further action on this proposed rule. If an adverse comment applies to an amendment, paragraph, or section of this proposed rule, and that provision may be addressed separately from the remainder of the proposed rule, we will withdraw only those provisions on which we received adverse comments. We will publish a timely withdrawal in the Federal Register indicating which provisions will become effective and which provisions are being withdrawn.","action":"Proposed rule; amendments.","agencies":[{"raw_name":"ENVIRONMENTAL PROTECTION AGENCY","name":"Environmental Protection Agency","id":145,"url":"https://www.federalregister.gov/agencies/environmental-protection-agency","json_url":"https://www.federalregister.gov/api/v1/agencies/145","parent_id":null,"slug":"environmental-protection-agency"}],"body_html_url":"https://www.federalregister.gov/documents/full_text/html/2001/04/10/01-8799.html","cfr_references":[{"chapter":null,"citation_url":null,"part":60,"title":40}],"citation":"66 FR 18579","comment_url":null,"comments_close_on":"2001-05-10","correction_of":null,"corrections":[],"dates":"Written comments on these proposed amendments must be received by May 10, 2001.
