Comments on the Massachusetts Department of Environmental Protection’s proposed amendments to 310 CMR 7.00 Air Pollution Control

Clean Air Task Force (“CATF”) respectfully comments on the Massachusetts Department of Environmental Protection (“DEP” or “Department”) proposed amendments to 310 CMR 7.00 Air Pollution Control, and 310 CMR 60.00, Air Pollution Control for Mobile Sources. The proposed amendments respond to the mandates found in the Global Warming Solutions Act, M.G.L. c. 21N (“GWSA”), as confirmed by the Supreme Judicial Court in Kain v. DEP, 474 Mass. 278 (2016). We confine our comments to the proposed rules governing the electric sector and the oil and gas methane emissions reductions (proposed 310 CMR 7.73, 7.74 and 7.75), as those are the areas in which CATF has most expertise, and therefore can most be of service to the Commonwealth’s efforts to regulate greenhouse gas emissions.
