Environmental Protection Agency January 13, 2015 – Federal Register Recent Federal Regulation Documents

The Environmental Protection Agency (EPA) is proposing to revise provisions of the Arizona Regional Haze (RH) Federal Implementation Plan (FIP) applicable to the Nelson Lime Plant. In response to a request for reconsideration from the plant's owner, Lhoist North America of Arizona, Inc. (LNA), we propose to replace the control technology demonstration requirements for nitrogen oxides (NOX) applicable to Kilns 1 and 2 at the Nelson Lime Plant with a series of revised recordkeeping and reporting requirements. Lastly, we are proposing a correction in the regulatory language of the final rule where a table listing the pollution emission limits for NOX and sulfur dioxide (SO2) at each kiln was misprinted. We are seeking comment on each of these proposed actions.

The Environmental Protection Agency (EPA) is proposing to approve state implementation plan (SIP) revisions submitted by California to address Clean Air Act (CAA or Act) requirements for the 2006 24-hour fine particulate matter (PM2.5) national ambient air quality standard (NAAQS) in the San Joaquin Valley (SJV) Moderate PM2.5 nonattainment area. These SIP revisions are the 2012 PM2.5 Plan, submitted March 4, 2013, and the Supplement, submitted November 6, 2014. The EPA is also proposing to disapprove interpollutant trading ratios identified in these SIP submittals for nonattainment new source review permitting purposes. Finally, the EPA is proposing to reclassify the SJV area, including Indian country within it, as a Serious nonattainment area for the 2006 PM2.5 NAAQS based on EPA's determination that the area cannot practicably attain this standard by the applicable Moderate area attainment date of December 31, 2015. Upon final reclassification as a Serious area, California will be required to submit a Serious area plan including a demonstration that the plan provides for attainment of the 2006 PM2.5 NAAQS in the SJV area by the applicable Serious area attainment date, which is no later than December 31, 2019, or by the most expeditious alternative date practicable, in accordance with the requirements of part D of title I of the CAA.
