# AGENCY:

Environmental Protection Agency (EPA). 

# ACTION:

Extension of public comment period. 

# SUMMARY:

EPA is announcing the extension of the public comment period on the proposed reconsideration amendments to the new source performance standards (NSPS) for electric utility steam generating units and industrial-commercial-institutional steam generating units. EPA originally requested comments on the proposed rule by March 12, 2007 (February 9, 2007,72 FR 6320). EPA is extending the deadline to March 26, 2007, and is now requesting written comments by that date. EPA received a request for a 15 day extension to the comment period from the Utility Air Regulatory Group, the Council of Industrial Boiler Owners, and the Coke Oven Environmental Task Force. The reason given for requesting the extension was the need for additional time to gather data and review the proposed amendments. Since the original comment period was 30 days, EPA finds this request reasonable.
