Riepilogo

EPA is approving a State Implementation Plan (SIP) revision submitted by the State of New Hampshire. The revision consists of a new rule, PART Env-A 623, "Prevention of Significant Deterioration (PSD) of Air Quality Permitting," that adopts into New Hampshire's SIP the federal PSD program provisions. The SIP revision also amends New Hampshire's permit procedural rule, PART Env-A 205, "Permit Notice and Hearing Procedures: Temporary Permits and Permits to Operate," to make the rule consistent with the new state PSD rule. The approval of this revision will make the New Hampshire PSD program consistent with the federal plan requirements for a SIP-approved PSD program. This action is being taken in accordance with the Clean Air Act.
