The valley's seven major industrial sources pumped 8,118 tons of sulfur dioxide into the air in 2008, a 10 percent reduction from the year before. [...] for the first time, the ConocoPhillips refinery became the valleys smallest source--emitting only 108 tons of sulfur dioxide--while processing a record amount of crude oil. Last year, the plant produced 30 percent of the valley's pollution, which includes sulfur dioxide, nitrogen oxide, particulate, carbon monoxide and volatile organic compounds.
EPA is approving in part and disapproving in part state implementation plan (SIP) revisions submitted by California to provide for attainment of the 1997 fine particulate matter (PM) national ambient air quality standards in the Los Angeles-South Coast area (South Coast). These SIP revisions are the South Coast 2007 Air Quality Management Plan (South Coast 2007 AQMP) (revised 2011) and South Coast-related provisions of the 2007 State Strategy (revised 2009 and 2011). EPA is approving the emissions inventory; reasonably available control measures/reasonably available control technology demonstration; the reasonable further progress and attainment demonstrations and associated air quality modeling; and the transportation conformity motor vehicle emissions budgets. EPA is also granting Cal...

Managers of several North Jersey indoor ice rinks say they have enough safeguards in place to ensure that skaters don't get sick from emissions from Zambonis and other ice-resurfacing machines like the entire hockey team that fell ill recently at a Rhode Island arena. The Fritz Dietl Ice Rink in Westwood recently installed a new exhaust system, including one in the room that houses its Zamboni. Floyd Hall Arena in Little Falls has nitrogen oxide and carbon monoxide detectors throughout the facility. The Ice House in Hackensack constantly pumps outdoor air into its rinks. And the Ice Vault Arena in Wayne has its two Zambonis tuned up at least twice a year.
EPA is finalizing its approval of most of the Nevada Regional Haze State Implementation Plan (SIP) that implements the Clean Air Act (CAA) Regional Haze Rule requiring states to prevent any future and remedy any existing man-made impairment of visibility in mandatory Class I areas through a regional haze program. EPA proposed to approve all parts of Nevada's SIP revisions on June 22, 2011 (76 FR 36450). This final approval applies to all aspects of Nevada's SIP except for that portion of Nevada's determination regarding the Best Available Retrofit Technology (BART) to reduce nitrogen oxide (NO<INF>X</INF>) emissions at the Reid Gardner Generating Station (RGGS). We will take action on BART for NO<INF>X</INF> at RGGS in a future notice.
