Abstract

The Environmental Protection Agency (EPA) is proposing revisions to the New Source Review preconstruction permitting program’s definition of “begin actual construction.” These proposed revisions would distinguish between construction of a stationary source and construction of non-emitting components or structures, while clarifying and codifying that the latter can occur before an owner or operator obtains an NSR air permit for a new major stationary source or major modification of an existing major stationary source. The revisions will update the definition of “begin actual construction” and add a definition of “pollutant-emitting activities” in the Federal NSR regulations for both Nonattainment New Source Review (NNSR) and Prevention of Significant Deterioration (PSD); revise the definition of “begin construction” and “commence construction” in the Federal minor NSR regulations applicable in Indian country; and address the applicability procedures for “begin actual construction” in the NNSR regulations.
