US: The Environmental Protection Agency (EPA) has sent for the White House Office of Management and Budget (OMB) to review its proposed revisions to its emissions rules for the Portland cement sector, ahead of a tentative 15 June 2012 deadline for issuing the revisions in line with a proposed consent decree with the industry.

The pending proposed revised rules undergoing OMB review will address not only the remand but also the EPA's May 2011 partial reconsideration of the cement rules - including standards for open clinker storage piles and start-up and shutdown monitoring requirements - as those provisions included in the recent proposed consent decree with industry.

In the Register notice on the consent decree, the EPA says that it "would also agree to propose to extend the existing source compliance date of 10 September 2013, or in any case to discuss the possibility of extending that date, and to take final action by 20 December 2012 regarding the date of compliance," if such provisions are 'supported by the administrative record.'

While stalling the compliance deadline would be a 'win' for the cement industry, it would likely draw protests from environmentalists supportive of the current air toxics rule. The deadline for comments on the proposed consent decree is 7 June 2012.
