      RE:	Request for Extension of Time  -  SBAR Panel: Risk and Technology Review

Dear Ms. Barch:

The North American Insulation Manufacturers Association ("NAIMA") appreciated the opportunity to meet with Environmental Protection Agency ("EPA"), Small Business Administration ("SBA"), and Office of Management and Budget ("OMB") representatives on April 27, 2011 to discuss the SBAR Panel Briefing: Risk and Technology Review for Mineral Wool Production.  At that meeting, a response from NAIMA was targeted for May 11, 2011.

In the interim, EPA has contacted NAIMA and requested additional information on formaldehyde binders and has also requested two plant visits.  NAIMA has become directly involved in both requests, including participating in the plant visits in Huntington and Wabash, Indiana.

Given the commitment of NAIMA to provide thorough and comprehensive information, NAIMA is requesting an additional ten days beyond the scheduled plants visits in Indiana on May 12, 2011 to provide NAIMA's preliminary response to the questions raised during the SBAR presentation.

This extension of time would facilitate the ongoing dialogue that has been both productive and cooperative. 

Sincerely,

Angus E. Crane

Angus E. Crane
Executive Vice President, General Counsel
