RESOURCES Subject: Permit No. WQ0004898 Town of Pikeville Pikeville Wastewater Treatment Facility Wastewater Treatment and Spray Irrigation Facilities Wayne County Dear Mr. Medlin; In accordance with your permit renewal application received on September 14, 2001, we are forwarding herewith Permit No. WQ0004898, dated December 12, 2001, to the Town of Pikeville for the continued operation of the subject wastewater treatment and spray irrigation facilities. This permit shall be effective from the date of issuance until November 30, 2006; shall void Permit No. WQ0004898, issued April 18,1997; and shall be subject to the conditions and limitations as specified therein. Be aware that the issuance of this permit shall not preclude the you .from complying with all terms and conditions of the most recent version of any Special Order of Consent approved by the Environmental Management Commission for the facilities. This permit approves the continued operation of the subject wastewater treatment and spray irrigation facilities for another five-year cycle. However, please tape the time to review this permit thoroughly as some of the conditions contained therein may have been added, changed, or deleted since the last issuance of this permit. Note, for example, that the requirement for sampling the groundwater monitoring wells has been removed from this permit because the Division of Water Quality (Division) believes that the data collected from the wells is not representative of the actual groundwater conditions due to their questionable integrity. Therefore, guidance for abandonment of MW-1 and MW-3 as well as potential new groundwater monitoring requirements will be added to this permit when it is modified by the Division's Construction Grants & Loans Section to accommodate implementation of the approved alternative from the 201 Facilities Plan. As always, 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 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. 1617 Mail Service Center, Raleigh, North Carolina 27699-1617 Telephone (919) 733-5083 Fax (919) 715-6048 An Equal Opportunity Affirmative Action Employer 50% recycled/10% post -consumer paper If you need additional information concerning this matter, please contact Ms. Shannon Mohr Thornburg at (919) 733-5083, extension 353.
