Provinces target coal-fired plants

Under the voluntary standard which has been in the works for years, ministers will also consider a further tightening of emissions limits to achieve 80 per cent capture after 2018.

But the agreement, announced recently at a federal-provincial meeting in Yellowknife, will pose major challenges for Ontario, which has four old coal-fired plants and no plan yet to replace them.

Mercury is a highly potent toxin that persists in the environment, builds up in the food chain and can cause neurological damage to humans, who are exposed mainly through eating fish.

The metal is also blamed for causing reproductive failure among loons and river otters.

"All of us are working on plans to have this as a standard for Canada," said Saskatchewan Environment Minister John Nilson, outgoing chairman of the Canadian Council of Ministers of the Environment.

He said Saskatchewan is reviewing its power needs for the next 20 years, and reducing mercury pollution is a central objective.

Ken Ogilvie, executive director of Pollution Probe, said the national standard is an important step forward.

"Mercury is a global problem of huge significance. The faster we move the better," he said.

Ogilvie said he would prefer that the ministers commit to 80 per cent capture sooner, because it is feasible with current technology.

Ontario Environment Minister Laurel Broten said her province will have a plan by spring for closing its coal-fired plants.

Broten said she expects the federal Conservative government to honour a $536 million agreement Ontario had reached with the former Liberal government to facilitate closure of the plants.

But Ottawa has not been clear on its intentions.

Even without federal money, she said, Ontario will phase out the plants.

"We are absolutely committed to the short-term goal of 60 per cent capture by 2010."
