Nova Scotia seeks comment on draft mercury emission limits from coal-fired plants
HALIFAX, NS-The Nova Scotia government is inviting public comments on draft Canada-wide Standards (CWS) for reduction of mercury emissions from coal-fired power plants. The proposed CWS, approved in principle in June by the Canadian Council of Ministers of Environment (CCME), will set provincial caps on annual mercury emissions from existing plants starting in 2010. Caps for individual provinces will depend on facilities and the type of coal burned. Nova Scotia's cap will be 65 kilograms per year, which is equivalent to reducing mercury emissions by 56%. These standards, combined with measures Nova Scotia Power has already taken, will reduce mercury emissions by more than 70% from 2000 levels. Together, the provinces will aim to achieve a proposed national capture rate-the percentage of mercury in coal that must be removed from emissions-of 65% for existing power plants. This is equivalent to reducing the mercury emissions by 50%. Copies of the draft standards are available on the Environment and Labour Web site, www.gov.ns.ca/enla/aq. Written comments should be sent by Monday, August 29, 2005 to the Air Quality Branch, Nova Scotia Department of Environment and Labour, PO Box 697, Halifax B3J 2T8, E-mail email@example.com.
