New Mexico Questions PNM Claims

New Mexico – The New Mexico Environment Department says it doesn't object to Public Service Company of New Mexico's request for more time to respond to a proposal that would require more emissions controls at one of its coal-fired power plants.

But the department is questioning claims by PNM that new equipment for controlling nitrogen oxides emissions at the San Juan Generating Station would cost between $750 million and $1 billion.

PNM has said the state's proposal would result in significant costs for its 500,000 customers.

Environment Secretary Ron Curry says he's disappointed PNM failed to plan for the proposed rule and is now threatening that its customers will have to pay for it.

The department says PNM would have to get regulatory approval before imposing the costs of complying with the rule on rate payers.
