{"abstract":"EPA is taking direct final action on a State Implementation Plan (SIP) revision submitted by the State of Maryland. This revision concerns a plan which demonstrates that the emissions reductions of volatile organic compounds (VOC) required in ozone attainment and marginal ozone nonattainment areas in Maryland are comparable to the reductions which would be achieved by Stage II vapor recovery (Stage II) in those same areas. EPA is approving the Stage II comparability plan in the State of Maryland in accordance with the Clean Air Act (the Act).","action":"Direct final 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/1998/12/09/98-32577.html","cfr_references":[{"chapter":null,"citation_url":null,"part":52,"title":40}],"citation":"63 FR 67780","comment_url":null,"comments_close_on":"1999-01-08","correction_of":null,"corrections":[],"dates":"This rule is effective on February 8, 1999, without further notice unless EPA receives adverse written comment by January 8, 1999.
