Vapor Intrusion: Opportunity for Comment with EPA

Last month, the Environmental Protection Agency published a notice for “Public Comment on the Development of Final Guidance for Evaluating the Vapor Intrusion to Indoor Air Pathway From Contaminated Groundwater and Soils (Subsurface Vapor Intrusion Guidance)” in the Federal Register. The draft of the Subsurface Vapor Intrusion Guidance was initially released for comment during 2002 and the EPA is planning on issuing final guidance by November 20, 2012.

This Rule will K(NOx)ck Your SOx Off – EPA Proposes New Clean Air Rule

On July 6, 2010, the USEPA proposed a new interstate transport of ozone and fine particulate rule for power plants. The goal of the rule is to achieve by 2014 a 72% reduction of sulfur dioxide (SO2) and a 54% reduction of oxides of nitrogen (NOx) from 2005 levels. The tri state area, like most of the states east of the Mississippi, is covered by this rule for both fine particulates and ozone. The sulfur and nitrogen oxides are fine particulates in the air.

Changing the Climate for Greenhouse Gas Regulation: Decisions by Appellate Court and EPA May Help to Pave the Way for Comprehensive Federal Legislation

Since late June, when the House narrowly passed the American Clean Energy and Security Act of 2009, the loud and rancorous debate over health care may have obscured another critical issue being considered by Congress: climate change and the regulation of greenhouse gas emissions. Decisions made public on successive days in September by a federal appellate court and the U.S. Environmental Protection Agency (EPA), however, may go a long way toward making wide-ranging federal controls over greenhouse gas emissions a reality.

EPA Proposes to Limit Greenhouse Gas Emissions from Largest Sources

On September 30, just days after finalizing its new rule on mandatory reporting of greenhouse gas (GHG) emissions, EPA announced that it is proposing to use existing Clean Air Act provisions to limits such emissions from the largest sources of such emissions. The proposed rule, which focuses on sources that emit more than 25,000 tons of GHGs per year, would subject hundreds of new sources and modifications to existing sources to EPA review each year. In total, according to EPA, some 14,000 large sources would come under the proposed rule, which requires them to obtain operating permits that include limits on GHG emissions.
