Summary of CO2 caps in MA and NH
Massachusetts
The regulation is 310 CMR 7.29 “Emissions Standards for Power Plants”
Announced by Gov. Jane Swift on 23 April 2001
Affected facilities: several characteristics basically define 6 facilities. Massachusetts is a deregulated market.
NOx
- on 1 October, 2004 1.5 lbs/MWh calculated over any consecutive 12 month period, recalculated monthly
- on 1 October, 2006 3.0 lbs/MWh calculated over any individual month
- no credit trading option exists
SO2
- on 1 October, 2004 6.0 lbs/MWh calculated over any consecutive 12 month period, recalculated monthly
- on 1 October, 2006 3.0 lbs/MWh calculated over any consecutive 12 month period, recalculated monthly AND shall not exceed 6.0 lbs/MWh over any individual month
- early reductions at the affected facility can be banked for use later with out penalty or discounting
- SO2 allowances can be purchased from the market and can be applied in a discounting ratio of 3 allowances for every ton emitted over the cap; this is above and beyond credits used to meet the Federal caps
Mercury (Hg)
- 1 Dec, 2002 DEP will complete evaluation of the technological and economic feasibility of controlling Hg in accordance with the NEG/ECP plan
- within 6 months of that, the DEP will propose standards for a compliance date of 1 October, 2006
CO2
- emissions for the year 2004 and 2005 must not exceed historical actual emissions
- emissions for 2006 and every year thereafter must not exceed 1800lbs/MWh average (=total CO2 emitted for the year/total MWh generated in that year)
- CO2 emissions caps can be met with offsite reductions or sequestration
If an affected facility chooses to meet any part of this regulation by adding controls or repowering one or more units at the facility and submits an application to do so by 1 January 2003, dates for meeting all requirements at all units at the facility move back two years (2004 to 2006, 2006 to 2008).
There are spaces reserved for possible future carbon monoxide (CO) and particulate mater (PM) regulations. Finally, there is also an annual reporting requirement for all of the above.
New Hampshire
Legislation HB 284 (Clean Power Act), was signed into law by Gov. Jeanne Shaheen on 9 May 2002.
Affected facilities: those “grandfathered” by the Clean Air Act, Merrimack Units 1 &2, Schiller Units 4, 5 & 6, and Newington Unit 1. All of these units are owned and operated by PSNH. Costs of compliance can be recovered through regulated rates.
SO2
- beginning 31 December 2006, total SO2 emissions from affected sources must not exceed 7,289 tons annually (75% less than current levels)
NOx
- beginning 31 December 2006, total NOx emissions from affected sources must not exceed 3,644 tons annually (70% less than current levels)
Mercury (Hg)
- a Hg cap will be suggested after the US EPA sets a national regulation but not after 31 March 2004. Compliance still appears to be 31 December 2006.
CO2
- from 31 December 2006 thru 31 December 2010, total CO2 emissions from affected sources must not exceed 5,425,866 tons annually. After this, a lower cap will be used to be suggested by 31 March 2004.
Allowances will be given out up to the cap. Additional allowances can be bought on national markets to meet the requirements.
For each 0.80 SO2 allowance purchased from upwind sources, the state will grant an additional 0.20 allowance. SO2 allowances doled out by the state will not exceed 20,000 each year.
NOx allowances cannot be bought for emission between 1 May and 30 September.
Early reductions of CO2 may be banked for future use in regional or national trading programs or to meet this emission cap.
Money spent on energy efficiency, new renewable energy, or conservation and load management projects, will receive emission allowances worth (on the market) the amount of the investment in such projects.
In the future, purchased Hg credits can only be used for the portion of this rule more stringent then federal requirements.
Various fines will be imposed on violators, including “not more than $25,000” per violation per day.
