{"abstract":"Pursuant to a proceeding for reconsideration, the EPA requests comment on a Clean Air Act (CAA) rule, the New Source Review (NSR) Aggregation Amendments, which was promulgated on January 15, 2009. The NSR Aggregation Amendments established a new interpretation of the existing NSR rules governing the modification of major sources by requiring sources and permitting authorities to combine emissions from nominally-separate activities at a major stationary source only when the activities are \"substantially related.\" This proposed reconsideration is in response to a petition from the Natural Resources Defense Council (NRDC) received on January 30, 2009. EPA requests public comment on all issues included in NRDC's petition. In light of the legal and policy issues raised in the petition and in our own review of the rule, EPA's preferred option is to revoke the NSR Aggregation Amendments. EPA is also proposing to extend the effective date of the stay by an additional 6 months, and soliciting comment on a longer extension of the stay.","action":"Proposed rule.","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/2010/04/15/2010-7534.html","cfr_references":[{"chapter":null,"citation_url":null,"part":51,"title":40},{"chapter":null,"citation_url":null,"part":52,"title":40}],"citation":"75 FR 19567","comment_url":null,"comments_close_on":"2010-05-17","correction_of":null,"corrections":[],"dates":"Comments.
