On December 11, 2018, the Maryland Department of the Environment (MDE), Air and Radiation Administration, incorporated revisions to their Carbon Dioxide (CO2) Budget Trading Program codified in Title 26 of the Code of Maryland Regulations Subtitle 09 (COMAR 26.09). Maryland is part of the Regional Greenhouse Gas Initiative (RGGI), a program created to reduce CO2 emissions from fossil fuel-fired electricity generators with a nameplate capacity of 25 megawatts (MW) or greater. To implement RGGI, each participating state has a CO2 Budget Trading Program based on a model rule from RGGI. The RGGI states have been conducting a Program Review that evaluates program success, program impacts, the potential for additional reductions, imports and emissions leakage, and offsets. It was during the 2016 Program Review that the RGGI states developed these revisions.

The following summarizes the COMAR 26.09 rule revisions:

  1. Reduces the size and structure of the cap and allowance apportionment,
  2. Adjusts the emissions budget from 2021-2025,
  3. Modifies the Cost Containment Reserve mechanism when allowance costs are too high and adds an Emissions Containment Reserve mechanism when they are too low,
  4. Eliminates the Reduction in Emissions of Sulfur Hexafluoride (SF6) and Reduction in Avoidance of CO2 Emissions from Natural Gas, Oil, or Propane End-Use Combustion Due to End-Use Energy Efficiency offset categories.
  5. Adjusts the remaining offset categories, and
  6. Adds new delegation language for alternate CO2 authorized account representatives.

This action, which was originally proposed for adoption on October 26, 2018, has been adopted as proposed. A Notice of Final Action was published on December 21, 2018 with an effective date of December 31, 2018.
