Back in 2006, the Ohio Legislature passed Senate Bill 265 which was hailed as the biggest change to air pollution control regulations in Ohio in several decades.  The center piece of the legislation was an exemption for smaller sources of air pollution (10 tons per year or less) from having to comply with Ohio’s Best Available

EPA is proposing a whole series of new inspection and testing requirements for underground storage tanks (USTs).  By expanding the types of UST systems covered under the rules, EPA is  proposing to extend application of all UST regulations to entities not previously regulated, such as hospitals and universities.

U.S. EPA finally issued its long awaited air pollution regulation aimed at reducing mercury emissions from coal-fired power plants- Mercury and Air Toxics Standards (MATS).  MATS sets specific numeric emission standards for mercury and other air toxics from coal-fire power plants  25 megawatts in size or larger.

MATS will apply to some 1,400 generating units across

In early November, the EPA sent to OMB the next significant regulation governing greenhouse gas emissions.  Under the latest rule, EPA would establish CO2 emission standards for new and modified coal-fired power plants. 

The new rule is titled the Greenhouse Gas New Source Performance Standard (NSPS) for Electric Utility Steam Generating Units.  The NSPS standards are based

Back in June, the Supreme Court agreed to hear the case of Sackett v. EPA which could forever change the way EPA enforcement actions are defended.  While the case involves an EPA administrative enforcement order for unauthorized filling of a wetland, the ruling potentially impacts EPA enforcement under all its major statutes- RCRA (hazardous waste), Clean Air
