Environmental Protection Agency April 24, 2009 – Federal Register Recent Federal Regulation Documents

Notice is hereby given that a petition has been received from the state of Maine requesting a determination by the Regional Administrator, U.S. Environmental Protection Agency, that adequate facilities for the safe and sanitary removal and treatment of sewage from all vessels are reasonably available for the waters of Southern Mount Desert Island.

EPA is approving a site specific revision to the Minnesota sulfur dioxide (SO2) State Implementation Plan (SIP) for the Rochester Public Utility's Cascade Creek Generating Facility (Cascade Creek), located in the city of Rochester, Olmsted County, Minnesota. On March 5, 2008, the Minnesota Pollution Control Agency (MPCA) requested that EPA approve certain portions of a joint Title I/Title V document into the Minnesota SO2 SIP for the Cascade Creek facility. This SIP revision includes the addition of two new oil and gas fired turbines and modification of the starter engine on the No. 1 turbine. This SIP revision will show reduced emissions of SO2 from this facility and the SO2 National Ambient Air Quality Standards (NAAQS) will be maintained in the area. Because the SO2 emission limits are being reduced, the air quality of Olmsted County will be protected.

EPA is approving a July 28, 2008, request from the Wisconsin Department of Natural Resources (WDNR) that EPA find that the Milwaukee-Racine, Wisconsin (WI) nonattainment area has attained the revoked 1-hour ozone National Ambient Air Quality Standard (NAAQS).

EPA is approving site specific revisions to the Minnesota sulfur dioxide (SO2) State Implementation Plan (SIP) for the Federal Cartridge Company and Hoffman Enclosures, located in the city of Anoka, Anoka County, Minnesota. On March 3, 2008, the Minnesota Pollution Control Agency (MPCA) requested that EPA approve certain portions of joint Title I/Title V documents into the Minnesota SO2 SIP for Federal Cartridge Company and Hoffman Enclosures. The state is also requesting in this submittal that EPA rescind the Administrative Order issued to Federal Hoffman, Inc. which is currently included in Minnesota's SIP for SO2. The emissions units previously owned by Federal Hoffman, Inc., are now owned by Federal Cartridge Company and Hoffman Enclosures. Because the sulfur dioxide emission limits are being reduced, the air quality of Anoka County will be protected.

Today the Administrator is proposing to find that greenhouse gases in the atmosphere endanger the public health and welfare of current and future generations. Concentrations of greenhouse gases are at unprecedented levels compared to the recent and distant past. These high atmospheric levels are the unambiguous result of human emissions, and are very likely the cause of the observed increase in average temperatures and other climatic changes. The effects of climate change observed to date and projected to occur in the futureincluding but not limited to the increased likelihood of more frequent and intense heat waves, more wildfires, degraded air quality, more heavy downpours and flooding, increased drought, greater sea level rise, more intense storms, harm to water resources, harm to agriculture, and harm to wildlife and ecosystemsare effects on public health and welfare within the meaning of the Clean Air Act. In light of the likelihood that greenhouse gases cause these effects, and the magnitude of the effects that are occurring and are very likely to occur in the future, the Administrator proposes to find that atmospheric concentrations of greenhouse gases endanger public health and welfare within the meaning of Section 202(a) of the Clean Air Act. She proposes to make this finding specifically with respect to six greenhouse gases that together constitute the root of the climate change problem: carbon dioxide, methane, nitrous oxide, hydrofluorocarbons, perfluorocarbons, and sulfur hexafluoride.
