The Commissioner of Environmental Protection recently gave notice of a public hearing on the Department of Environmental Protection's (DEP) proposed regulation: Section 22a-174-42. This rule would set emissions limitations for both existing and new DG sources. A public hearing will be held on April 7, 2004 in Hartford, CT.
Section 22a-174-42 ("Section 42") encourages the deployment of environmentally sustainable distributed generators; encourages technological improvement to reduce emissions output from such generators; and regulates emissions from distributed generators consistent with the Ozone Transport Commission recommendation in its March 28, 2001 "Resolution of the States of the Ozone Transport Commission Concerning the Creation of Incentives for Additional Clean Distributed Generation of Electric Power." The requirements include output-based standards for emissions of oxides of nitrogen, particulate matter, carbon monoxide and carbon dioxide as well as fuel sulfur content requirements to control emissions of sulfur dioxide and, for new generators, a standard for ammonia emissions. The requirements restrict emissions to levels below the permit applicability thresholds for minor sources set forth in R.C.S.A. section 22a-174-3a ("Section 3a").
Distributed Generator means any new or existing generator with a nameplate capacity less than 15 MW that generates electricity for other than emergency use. Electricity generated may be used either onsite or for sale under an agreement with a utility, other market participant or system operator. Such a generator may also generate electricity for use during an emergency but is not defined as an emergency generator.
