Service Center DENR . WATER QUALITY Raleigh NC 27699-1617 POINT SOURCE BRANCH Subject: Belews Creek Steam Station (BCSS) — Stokes County Temporary and Permanent Pumping Systems Withdrawal of Water from Dan River to Belews Lake Per our recent discussions, approval for temporary pumping of water from the Dan River to raise the lake level of Belews Lake will lie necessary again this winter to ensure uninterrupted power production by BCSS in 2010. The current lake level is tracking the levels recorded in 2001 and 2007. Based on the BCSS operating experience during the drought conditions of 2001-2002, 2007, and 2008 and the increased evaporative loss due to the new flue gas desulfurization systems operation in 2008 and 2009, construction of a permanent pumping system is proposed in 2010. Enclosed are 3 copies of the completed preconstruction notification (PCN) form with the required information needed for coordination of review by the Division of Water Quality (DWQ) and other appropriate agencies. Included with the PCN submittal are copies of past DWQ authorizations to operate the temporary pumping system. Approval to install and operate the temporary system again this fall and winter is requested immediately. Approval for construction of the permanent pumping system is needed as soon as possible in order to have the system available in November 2010 for operation on as needed basis per available river flow. Should you have questions regarding the enclosed information, please call me at (980) 373-5710. Sincerely, Ronald E.
