chlor-alkali facilities were also reduced by more than 90%
though the use of best management practices at a facility in
New Brunswick and the closure of a facility in Maine.
Regulations and legislation targeting coal-fi red EGUs in
New England are now being implemented and will result
in further substantial reductions in regional mercury emis-
sions. These state requirements will achieve considerably
greater emission reductions under faster implementation
timeframes than the vacated CAMR. For example, legisla-
tion adopted in Connecticut in June 2003 established an
emission control target of 90% by 2008 for coal-fi red units
in that state (Connecticut General Assembly 2003). In 2004,
Massachusetts adopted stringent emission limits for this sector
based on an analysis of mercury emission levels and control
technology options (MassDEP, 2002, 2003, 2004a). The regu-
lations phase in emission reduction requirements in two steps,
culminating in a 95% emission control requirement in 2012.
The anticipated emission reductions under these regulations
are depicted in Figure 16.1.

The region has continued to advance effective mercury
pollution-prevention initiatives on many fronts. The New
England states have taken cutting-edge leadership positions
regarding product stewardship for mercury-added prod-
