The Republican-controlled House is continuing its campaign against environmental regulations, this time passing a bill to delay rules to curb toxic air pollution from industrial boilers and incinerators.
The legislation passed 274-142 on Thursday. It joins a host of other measures aimed at weakening, delaying or scrapping EPA regulations that Republicans view as job killers.
The measures have little chance of passing the Democratic-controlled Senate. The White House has threatened to veto them.
The boiler rule would have reduced toxic emissions and mercury from more than 13,000 large boilers. Boilers burn coal and other fuels for heat and electricity.
The EPA already had cut compliance costs and delayed the rule until April 2012 due to industry criticism.
