SUPPLEMENTARY INFORMATION: I. Background MSHA issued an Emergency Temporary Standard (ETS) on May 22, 2007, (72 FR 28796), and extended the comment period to September 17, 2007. MSHA is seeking additional public comment on the Report. The Report summarizes the preliminary results of a study performed under contract (MSHA NO 1A-AR 6000012) for MSHA's Technical Support Directorate (Technical Support) by the U.S. Army Corps of Engineers (USACE). The USACE conducted research and testing from August 2006 to April 2007. The USACE provided a draft of the Report of their findings to Technical Support in May of 2007. The Report details the USACE's efforts to mathematically model the methane explosion at the Sago Mine and potentially establish the seal overpressures. The Report was not finalized. MSHA is expressly limiting comments to those which address the Report as it relates to the regulatory provisions in the ETS. The Report is available on the Internet at: 
                    *http://www.msha.gov/​CFDSagoReport.pdf.*
                     This notice allows commenters sufficient time to review the Report and submit comments. All comments and other appropriate data must be received by midnight, January 18, 2008, Eastern Standard Time. II.
