The state of New Hampshire participates in the Regional Greenhouse Gas Initiative (RGGI) with other Northeast and Mid-Atlantic States, which is a market-based program designed to reduce greenhouse gases. The New Hampshire Department of Environmental Services (NHDES) published the following approved changes to its RGGI-implementing rules on January 14, 2020:

  • Amendments of the New Hampshire Code of Administrative Rules - Env-A 4600: CO2 Budget Trading Program
  • Repeal of the New Hampshire Code of Administrative Rules - Env-A 4700: Carbon Dioxide (CO2) Offset Projects

All changes were effective January 1, 2020.

The repeal of Env-A 4700 means that New Hampshire will no longer award CO2 offset allowances under the Regional Greenhouse Gas Initiative (RGGI). However, regulated power plants located in New Hampshire are still eligible to use CO2 offset allowances awarded by another RGGI state.

The final CO2 budget trading program rule can be viewed here. The changes include:

  1. The cost containment reserve trigger price (CCR trigger price) is set for $10.77 per CO2 allowance for 2020, $13.00 per CO2 allowance in 2021, and 1.07 multiplied by the CCR trigger price for the previous calendar year for each calendar year thereafter
  2. The base budget is reduced to 3.96 million allowances and provides that the allowances decline by approximately 119,000 tons of CO2 every year thereafter
  3. The exemptions for units combusting biomass and the definition of “participating state” are clarified
  4. The quantity of first and second control period banked allowances are established
  5. The CO2 authorized account representative (AAR) or alternate AAR may delegate authority to review the CO2 allowance tracking system
