{"abstract":"Notice is hereby given that EPA has performed an analysis to evaluate emission levels of oxides of nitrogen ( NO<INF>X</INF>) and volatile organic compounds (VOC) and their relationships to the application of current and anticipated control measures expected to be implemented in four serious one-hour ozone nonattainment areas. This analysis was done to determine if additional reasonably available control measures (RACM) are available after adoption of Clean Air Act (Act) required measures for the following serious ozone nonattainment areas: Greater Connecticut, New York-New Jersey-Connecticut; Springfield, Massachusetts; Washington, D.C.-Virginia-Maryland; and Atlanta, Georgia. The EPA performed this analysis in response to comments that were submitted on the proposals on these areas' one-hour ozone attainment demonstrations. The EPA took action to propose approval (and disapproval in the alternative) of these areas' State implementation plans (SIPs) on December 16, 1999 (Greater Connecticut (64 FR 70332); Springfield (64 FR 70319); Metropolitan Washington (64 FR 70460); and Atlanta (64 FR 70478)). This information supplements the December 16, 1999 proposals.","action":"Notice of availability and reopening of comment period.","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/2000/10/16/00-26612.html","cfr_references":[{"chapter":null,"citation_url":null,"part":52,"title":40}],"citation":"65 FR 61134","comment_url":null,"comments_close_on":"2000-10-31","correction_of":null,"corrections":[],"dates":"The EPA is establishing a comment period, ending on October 31, 2000.
