The Massachusetts Department of Environmental Protection (MassDEP) adopted 310 CMR 7.70, Massachusetts Carbon Dioxide (CO2) Budget Trading Program. MassDEP also announces final amendments to 310 CMR 7.29, Emissions Standards for Power Plants, and 310 CMR 7.00 Appendix B(7), Greenhouse Gas (GHG) Credit Banking and Trading Program. Specifically, these amendments will terminate the CO2 requirements of 310 CMR 7.29 on December 31, 2008, and terminate the GHG Credit Banking and Trading Program in 2013. These amendments facilitate the transition to 310 CMR 7.70 by combining and postponing the final compliance date for the CO2 emissions standards of 310 CMR 7.29 until September 1, 2009, expanding the geographic scope for the creation of GHG credits, and allowing for the limited discounted exchange of Massachusetts GHG Credits for Massachusetts CO2 Budget Trading Program allowances. http://mass.gov/dep/air/laws/regulati.htm#co2trade.
