Air Plan Approval; NH; Regional Haze 5-Year Report

The Environmental Protection Agency (EPA) is approving a State Implementation Plan (SIP) revision submitted by the State of New Hampshire on December 16, 2014. New Hampshire's SIP revision addresses requirements of the Clean Air Act (CAA) and EPA's rules that require States to submit periodic reports describing progress toward reasonable progress goals (RPGs) established for regional haze and a determination of the adequacy of the state's existing Regional Haze SIP. In addition, the December 16, 2014 submittal includes a revised regulation that reduces the total suspended particulate (TSP) emission limit for the state's sole Tangential-Firing, Dry-Bottom Boiler.
