Ross Jr., Secretary North Carolina Department of Environment and Natural Resources O Alan W. Klimek, P.E., Director Coleen H. Sullins, Deputy Director Division of Water Quality March 31, 2004 Mr. Michael T. Walker, Chairman Seagrove-Ulah Metropolitan Water District P. O. Box 370 Seagrove, North Carolina 27341 Subject: Permit No. WQ0002648 Con Agra Grocery Products Co. Wastewater Surface Irrigation Randolph County Dear Mr. Walker: In accordance with your permit application request for modification received February 25, 2004, we are forwarding herewith Permit No. WQ0002648, dated March 31, 2004, to Seagrove-Ulah Metropolitan Water District for the continued operation of the subject wastewater treatment and surface irrigation facilities. The purpose of this modification is to change the owner of record from Con Agra Grocery Products Co. to Seagrove- Ulah Metropolitan Water District. Please note the most recent soil scientist report (by Toney C. Jacobs, dated January 12, 1995) allows a loading rate of 38.4 inches/acre/year for the existing subject 40 acre spray irrigation field. The 300,000 GPD, allowed in the previous wastewater permits far exceeds the 38.4 inches/acre/year loading rate. The submitted application package indicates a total treatment capacity of 120,000 GPD from the 30,000 GPD sanitary package treatment plant, the 60,000 GPD process waste package treatment plant, and the estimated 30,000 GPD of contact cooling water. This only allows approximately 5 days of storage, for the 588,000 gallon capacity of the wet weather storage pond. By calculation for a 365. day work year, the existing 40 acre spray field can handle an approximate average of 114,261 gallons per day. By calculation, for the 120,000 GPD rate, the 38.4 inches/acre/year spray field loading rate could accommodate approximately 346 work days per year. The Division has been assured the subject ConAgra Grocery Products Company plant will take all steps necessary to prevent any over flow of the storage pond or runoff from the spray field. Therefore, this permit must reduce the previously allowed 300,000 GPD flow to the 120,000 GPD total treatment capacity. ConAgra Grocery Products Company (Seagrove-Ulah Metropolitan Water District) is cautioned that it would be a violation of this permit to allow any over flow of the storage pond or runoff from the spray field. This permit shall be effective from the date of issuance unt April 3 5, shall void Permit No. WQ0002648 issued November 11, 2001, and shall be subject to the con 1tlons and limitations as specified therein. Please pay particular attention to the monitoring requirements in this permit. Failure to establish an adequate system for collecting and maintaining the required operational information will result in future compliance problems. If any parts, requirements, or limitations contained in this permit are unacceptable, you have the right to request an adjudicatory hearing upon written request within thirty (30) days following receipt of this permit. This request must be in the form of a written petition, conforming to Chapter 150B of the North Carolina General Statutes, and filed with the Office of Administrative Hearings, 6714 Mail Service Center, Raleigh, NC 27699- 6714. Unless such demands are made this permit shall be final and binding.
