Nitrogen Oxide (NOx) Ozone Season Net Output Reporting

Under 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 EPA’s Clean Air Interstate Rule (CAIR), effective January 1, 2015. 

Although the federal CAIR program and consequently the MassCAIR program have ended, MassDEP monitoring, reporting and record-keeping requirements remain in effect. 

NOx Ozone Season Units with (1) electric output ratings of 15 megawatts (Mw) or more or (2) maximum design heat input of 250 million British thermal units per hour (MMBTu/hr) or more are required to submit Net Output Reports providing net electrical and/or steam output information after each Ozone Season.

NOx Ozone Season Net Output Reports are due on December 1 annually. Completed forms should be sent via email to: michelle.blanchard@state.ma.us

Regional Greenhouse Gas Initiative (RGGI) Annual Net Output Reporting

The Commonwealth of Massachusetts participates in the Regional Greenhouse Gas Initiative (RGGI), 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 have been incorporated into the Massachusetts CO2 Budget Trading Program regulations at 310 CMR 7.70.  

CO2 Budget Units that at any time since January 1, 2005, have served electricity generators with nameplate capacity of 25 megawatt (Mw) equivalents or more are required to (1) submit and receive approval for output monitoring plans that include methods for quantifying net energy output and (2) submit RGGI Annual Net Output Reports providing net electrical and/or steam output each year.

RGGI Annual Net Output Reports are due on March 1 annually. Completed forms should be sent via email to: michelle.blanchard@state.ma.us
