Comment Period

After considering the request received from North American Insulation Manufacturers Association (NAIMA) to extend the public comment period, the EPA has decided to extend the public comment period for an additional 30 days. Therefore, the public comment period will end on January 14, 2015, rather than December 15, 2014. This extension will help ensure that the public has sufficient time to review the proposed rule and the supporting technical documents and data available in the docket.
