EPA Regulatory News

  • EPA issued final changes to Clean Air Act standards for major and area source boilers and commercial/industrial solid waste incinerators.  For more information go to

  • EPA revised the non-hazardous secondary materials rules (NHSM) which defines which materials are, or are not, “solid waste” when burned in combustion units.  For additional information go to

  • EPA issued a memo regarding the deferred deadline for reporting inputs to emissions equations under 40 CFR Part 98 until March 2013.  The deadline for reporting of inputs to emissions equations was deferred in August 2011 to allow EPA to evaluate concerns by reporters that the inputs were Confidential Business Information (CBI).  The subparts affected by the deferred reporting deadline include the following:

·         C – Stationary Fuel Combustion

·         D – Electricity Generation

·         DD – SF6 from Electrical Equipment Use

·         FF – Underground Coal Mines

·         HH – Municipal Landfills

·         II – Industrial Wastewater Treatment

·         SS – Electric T&D Equipment Manufacturing

·         TT – Industrial Waste Landfills

EPA has concluded that the data elements in question are not CBI.  As such, these data elements will have to be reported in the next GHG report (due by April 1, 2013).  The input fields to capture these data elements will be added to EPA’s electronic greenhouse gas reporting tool (e-GGRT).  One of the more important things resulting from EPA’s determination is that reporters will not only have to input these data elements for 2012, but also go back and include this data for reports submitted for 2010 and 2011 emissions, as applicable.   Please refer to the link for more information: http://www.epa.gov/ghgreporting/reporters/cbi/index.html

  • EPA is proposing to approve revisions to the Wisconsin State Implementation Plan (SIP), submitted by the Wisconsin Department of Natural Resources (WDNR) to EPA on May 4, 2011, June 20, 2012, and September 28, 2012. The proposed  revisions modify Wisconsin’s Prevention of Significant Deterioration (PSD) program to establish appropriate emission thresholds for determining which new stationary sources and modification projects become subject to Wisconsin’s PSD permitting requirements for their greenhouse gas (GHG) emissions. Additionally, these revisions propose to defer until July 21, 2014, the application of the PSD permitting requirements to biogenic carbon dioxide (CO2) emissions from bioenergy and other biogenic stationary sources in the State of Wisconsin. EPA is proposing approval of Wisconsin’s revisions because the Agency has made the preliminary determination that these revisions are in accordance with the Clean Air Act (CAA) and EPA regulations regarding PSD permitting for GHGs.

  • EPA proposed to determine that the Milwaukee-Racine, Wisconsin area had attained the 2006 24-hour fine particle (2006 PM 2.5) National Ambient Air Quality Standard (NAAQS). EPA received several comments on the original proposal, including one suggesting that the suspension of certain Clean Air Act (CAA) requirements cannot be applied in this instance because it only pertains to the 1997 PM 2.5 NAAQS and not to the 2006 PM 2.5 NAAQS. As a result, EPA is reproposing a narrow portion of our original determination to address this issue. We will address all comments received on the original proposal and this proposal in our final notice.  Comments must be received on or before January 28, 2013.  To view entire Federal Register entry go to http://www.gpo.gov/fdsys/pkg/FR-2012-12-28/html/2012-31290.htm
