The EPA on Tuesday amended its national volatile organic compound (VOC) emission standards for aerosol coatings, which establishes national reactivity-based emission standards for the aerosol coatings category under section 183(e) of the Clean Air Act.

The amendments add compounds and associated reactivity factors to Table 2--Reactivity Factors based on petitions the agency received from regulated entities, and clarify which VOCs are to be quantified in compliance determinations, according to the agency.

The final rule makes certain changes related to the notice required for a company to certify that it will assume the responsibility for compliance with recordkeeping and reporting requirements for a regulated entity, and it also addresses which party is liable following such a certification, the EPA said. The agency also noted a few minor revisions and corrections to the aerosol coatings reactivity rule.

The deadline for submitting the initial notifications required in one section of the aerosol coatings regulations for has been extended 30 days, until July 31, 2009.
