Notice ofIntent to Adopt and Amend Air Quality Regulations and to Revise the State Implementation Plan In accordance with the provisions of section 4-168(a) ofthe Connecticut General Statutes (CGS). the Commissioner ofthe Department ofEnergy and Environmental Protection (DEEP) hereby gives notice that it proposes to adopt and amend regulations concerning the sulfur content offuel used in stationary sources ofair pollution, under the authority ofCGS sections 22a-6 and 22a174. Upon adoption, the amended and adopted regulations will be submitted to the U.S

. Environmental Protection Agency (EPA) as a revision to the State Implementation Plan (SIP) for air quality. Description. DEEP is proposing to: • Adopt, in new section 22a-l74-19b ofthe Regulations ofConnecticut State Agencies (RCSA), fuel sulfur content restrictions for distillate, residual, kerosene and aviation fuels used in all non-mobile equipment for purposes other than heating; • Eliminate the less stringent fuel sulfur content restrictions ofRCSA section 22a-174-19; and • Remove outdated provisions in RCSA section 22a- l 74-19a, without changing the current requirements regulating S02 emissions from large electric generating units and industrial boilers

. The primary purpose ofthis proposal is to limit the sulfur content offuel oils burned in stationary sources to reduce emissions ofsulfur dioxide (S02) , an air pollutant and a contributor to the formation ofthe pollutant fine particulate matter (PM2 .5). The reduction in S02 emissions is important to reduce visibility-impairing emissions that contribute to regional haze and protect the public health from the adverse health impacts of S02 and PM2.s pollution. This proposal does not regulate the sulfur content ofheating oil to which CGS section 16a-21a applies. Written comments. Interested persons are invited to comment on the proposal. Comments should be submitted no later than October 10, 2013 to Wendy Jacobs, DEEP, Bureau ofAir Management, Engineering and Enforcement, 79 Elm Street, Hartford, Connecticut 06106-5127.
