Next steps for MassDEP Output Reporting

  1. What to Know

    The owners/operators of certain facilities in Massachusetts are required to report net electrical output and/or steam output to the Department of Environmental Protection (MassDEP) on an annual basis.

    RGGI Annual Net Output Reporting

    Massachusetts participates in the Regional Greenhouse Gas Initiative (RGGI). This is an ongoing effort among Northeast and Mid-Atlantic States to develop and implement a regional carbon dioxide (CO2) cap-and-trade program aimed at stabilizing and then reducing CO2 emissions from large fossil fuel-fired electricity generating units.

    RGGI requirements are incorporated into the Massachusetts CO2 Budget Trading Program regulations at 310 CMR 7.70.  

    The owner/operator of a CO2 Budget Unit that at any time since January 1, 2005, has served electricity generators with nameplate capacity of 25 megawatt equivalents (MWe) or more is required to submit a RGGI Annual Net Output Report after each calendar year, providing annual net electrical and/or net steam output.

    NOx Ozone Season Net Output Reporting

    In response to a 2014 U.S. Court of Appeals decision, the U.S. Environmental Protection Agency (EPA) implemented the Cross-State Air Pollution Rule (CSPAR) to supersede its Clean Air Interstate Rule (CAIR), effective January 1, 2015. The federal CAIR program, and consequently the MassCAIR program, ended as a result.

    MassDEP replaced the MassCAIR program with the MassNOx program effective March 9, 2018. Facilities are not required to report ozone season net output data under the MassNOx program.
