American Lung Association, Earthjustice, Environmental Advocates of New York, Jobs to Move America, New York Public Interest Research Group, New Yorkers for Clean Power, and Sierra Club submit comments on the New York State Department of Environmental Conservation’s (DEC) proposed amendments to its regulations implementing the Diesel Emission Reduction Act of 2006 (DERA). We applaud DEC’s proposed amendments that extend DERA’s requirements to use ultra-low sulfur diesel and best available retrofit technology to heavy-duty vehicles operated on behalf of State agencies, and not just those vehicles directly owned, operated, or leased by State agencies
