Preston Howard, Jr., P.E., Director October 15, 1997 Doug McMillan, Chief Executive Officer The Capital Area YMCA Post Office Box 10976 Raleigh, North Carolina 27605 Subject: Permit No. WQ0007144 The Capital Area YMCA Camp Seafarer Wastewater Spray Irrigation Pamlico County Dear Mr. McMillan: In accordance with the renewal request received July 14, 1997, we are forwarding herewith Permit No. WQ0007144, dated October 15, 1997, to The Capital Area YMCA for the continued operation of the subject wastewater treatment and spray irrigation facilities. This permit restricts the number of camp occupants to an average weekly camp occupancy limit of 750 persons per day. This limit is based on the calculated capacity of the active spray irrigation field and to allow effective control of any wastewater storage build-up in the existing treatment lagoon. This limit was calculated using the water balance, the disposal capacity, and the projected occupancy rate. If The Capital Area YMCA wishes to increase the number of campers and staff above this limit, an engineering study and a complete permit amendment application must be submitted to the Division for review. The engineering study must demonstrate there is adequate long term storage and spray field capacity to handle the additional wastewater, the proposed change will generate. This permit shall be effective from the date of issuance until September 30, 2002, shall void Permit No. WQ0007144 issued December 31, 1996, and shall be subject to the conditions 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, P.O. Drawer 27447, Raleigh, NC 27611-7447. Unless such demands are made this permit shall be final and binding. P.O.
