AGENCY:

Environmental Protection Agency (EPA).

ACTION:

Proposed rule; extension of the comment period.

SUMMARY:

EPA is extending the comment period for a proposed rule which published on January 6, 2011 (76 FR 758). In the 76 FR 758 Federal Register, EPA proposed to disapprove the revisions and new rules as submitted by the State of Montana on October 16, 2006 and November 1, 2006. EPA found that these revisions and new rules, pertaining to the regulation of oil and gas well facilities and applicability to Montana's air quality permitting requirements, do not meet the requirements of the Clean Air Act and EPA's Minor New Source Review (NSR) regulations. The 76 FR 758 Federal Register also stated that comments must be received on or before February 7, 2011. EPA is extending the comment period through February 28, 2011, due to a request from several commenters for an extension.

DATES:

Comments must be received on or before February 28, 2011.
