Thresholds for greenhouse gas permitting announced

On May 13, the US Environmental Protection Agency (EPA) announced its final “GHG Tailoring” rule to address greenhouse gas (GHG) emissions from stationary sources. The phased-in approach will initially address large facilities like power plants and oil refineries that emit most of the greenhouse gases from stationary sources. The regulated GHGs include carbon dioxide, methane, nitrous oxide, hydrofluorocarbons, perfluorocarbons and sulfur hexafluoride.

Those facilities will be required to include GHGs in their permit if they increase their GHG emissions by 75,000 tons per year (tpy). In July 2011, permitting requirements will expand to cover all new facilities with GHG emissions of at least 100,000 tpy and modifications at existing facilities that would increase GHG emissions by at least 75,000 tpy. The permits must demonstrate the use of best available control technologies to minimize GHG emission increases when facilities are constructed or significantly modified. EPA estimates approximately 900 additional permitting actions covering new sources and modifications to existing sources would be subject to review each year. In addition, 550 sources will need to obtain operating permits for the first time because of their GHG emissions.

Permitting requirements for smaller sources will await the findings of a 5-year study of the effects of GHG permitting of these sources, slated for completion in 2015.

According to the EPA press release announcing the final rule, the agency received about 450,000 (!) comments within the 60-day public comment period that followed issuance of the proposed rule in October 2009.

What do you think? Has EPA struck the proper balance between regulating a significant threat to health and the environment and providing relief to small businesses and farms?

For “major” sources of air pollution, the hits keep coming…

In a matter of a few weeks, the US Environmental Protection Agency (EPA) has proposed several actions that could have dramatic impacts for facilities subject to Clean Air Act New Source Review (NSR) provisions (i.e., major sources of air pollutant emissions).  These actions address the grandfathering provision for fine particulate emissions, the fugitive emissions rule and the aggregation rule.  To wit:

  • On February 4, EPA proposed to repeal the NSR “grandfathering provision” for emissions of particulate matter less than 2.5 microns, or micrometers, in diameter (PM2.5), commonly termed “fine particulates.”  The rule had allowed permit applicants to rely on permitting requirements for “coarse particulates” – particulate matter 10 microns or less in diameter, or PM10 -  as a surrogate for PM2.5 requirements if the application had been submitted prior to July 15, 2008.  The EPA proposal also will end the “PM10 surrogate policy” by no later than May 2011, eliminating the use of PM10 as a substitute for PM2.5 analysis in State permitting programs.

EPA formally announces greenhouse gas permitting schedule

The US Environmental Protection Agency (EPA) has announced  that Clean Air Act permits for stationary sources of greenhouse gases (GHGs) will not be required before January 2011 – or, to put it another way, EPA has put the largest sources of greenhouse gas emissions on notice that permitting will commence in January 2011.

Clean Air Act construction and operating permit requirements for the facilities emitting the largest quantities of GHGs will begin when the first national GHG control rule takes effect.  EPA’s target date for implementation of a rule regulating GHG emissions from cars and light trucks is January 2011, when model year 2012 vehicles meeting the standards can first be sold in the United States.  Final greenhouse gas emissions standards for vehicles are pending. image: air emissions stacks at industrial facility

At this point, potentially regulated sources are still waiting for EPA to formally reveal the threshold quantities of GHG emissions that will trigger the requirement for permit limitations on these emissions.

What do you think – too soon?  Can we expect that regulators and regulated industries will be able to identify, engineer and implement effective control technologies and procedures in timely fashion?  And how will the costs affect not only the permitted industries but also chances for an economic recovery?
