Environmental Protection Agency (EPA) Region 4 (Region 4) is proposing to approve a portion of a State Implementation Plan (SIP) revision submitted by the state of North Carolina, through the North Carolina Division of Air Quality (NC DAQ), in a letter dated June 5, 2017, which changes North Carolina's SIP-approved rule regarding nitrogen oxides (NO<INF>X</INF>) emissions from large internal combustion engine sources. In so doing, Region 4 is first considering adopting an alternative policy regarding startup, shutdown, and malfunction (SSM) exemption provisions in SIPs that departs from EPA's 2015 national policy on this subject and, accordingly, if that policy is adopted, is also proposing to withdraw the SIP call issued to North Carolina for exemptions contained in the existing SIP-approved provisions for SSM events.
