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. Mr- Non -Discharge Permitting Unit Internet http:/lh2o.enr.state.ne.us/ndpu R
