The EPA on Monday announced it intends to reconsider portions of three rules under its New Source Review (NSR) permitting program. According to an agency release the "rules under review determine when and how facilities are required to account for air emissions that are not released through a stack, vent or other confined air stream; keep records on emissions; and account for air emissions associated with fine particle pollution when obtaining a permit."
In its release, the EPA noted it will will publish a notice of proposed rulemaking in the Federal Register requesting comment on certain aspects of each of these three rules.
Also in NSR news, the EPA released its final amendments to the Standards of Performance for Nonmetallic Mineral Processing Plants (NMPP). These amendments include revisions to the emission limits for NMPP-affected facilities that commenced construction, modification or reconstruction on or after April 22, 2008. These final amendments for NMPP also include additional testing and monitoring requirements for affected facilities that commence construction, modification, or reconstruction on or after April 22, 2008; exemption of affected facilities that process wet material from this final rule; changes to simplify the notification requirements for all affected facilities; and changes to definitions and various clarifications.
The agency did not take final action in this document regarding the amendment to the Standards of Performance for Calciners and Dryers in Mineral Industries, even though the agency discussed doing so in the proposed rule. This final rule became effective on April 28, 2009.
