Dear Mr. Autry:
William G. Ross Jr., Secretary
North Carolina Department of Environment and Natural Resources
Coleen H. Sullins, Director
Division of Water Quality
Enclosed please find a copy of the Compliance Evaluation Inspection form from the inspection conducted on August 20, 2007.
The Compliance Evaluation Inspection was conducted by Mark Brantley, Environmental Chemist, of the Fayetteville Regional
Officer -The facility was found to be in Compliance with permit NC0043176. The cooperation of-Donrie Dukes, Grade IV
ORC, was greatly appreciated. As a reminder, preservation of the Waters of the State can only be achieved through consistent
NPDES Permit compliance.
Comments
• Facility was clean and neat in appearance at the time of the inspection.
• Plant staff is taking advantage of the dry conditions by taking one clarifier a week off line for annual routine and
preventive maintenance measures. -
• Also during the inspection it was noted that powder soda ash (which is used to help maintain proper effluent pH) was
stored in the blower building next to the blowers that supply air to the aeration basin: The Fayetteville Regional ' "
Office of the Division of Water Quality strongly encourages the facility to store the soda ash in a more appropriate
place away from any mechanical machinery as the soda ash may cause unnecessary corrosion or other damage to the
Machinery. It may be -necessary to construct a separate storage area.
Please refer to the enclosed inspection report for additional observations and comments. If you or your staff have any
questions, please call me at 910-433-3327.
