In accordance with the application for a discharge permit received October 28, 1996, the Division is forwarding herewith the subject NPDES permit. This permit is issued pursuant to the requirements of North Carolina General Statute 143-215 1 and the Memorandum of Agreement between North Carolina and the US Environmental Protection Agency dated December 6, 1983 Please note that all concerns, in reference to the draft permit, identified in the comment letter dated August 18, 1997, have been made as requested except for the following• • Part I, Page 2 of 9 CP&L requested less frequent monitoring for the following parameters: total phosphorus (TP), total nitrogen (TN), and arsenic Monitoring for TP and TN is mandated by the Administrative Code Section 2B 0500. This section states that monthly monitoring for TP and TN is required for all facilities that discharge 1 MGD or higher. Therefore, the monitoring frequency for TP and TN will remain as monthly. In response to reducing the monitoring requirement for arsenic, it is division policy to require monthly monitoring for all toxicants at facilities classified as class I or class II CP&L is classified as a class II facility so monthly monitoring is appropriate • Part I, Page 5 of 9 The limits page for outfall 008 can not be deleted as requested. CP&L is responsible for the proper operation and maintenance of the treatment facility to ensure treatment of domestic wastewater to secondary standards. The Division feels that it is necessary to keep this effluent monitoring page in the permit so there is no misunderstanding as to what constitutes "proper operation and maintenance." • Part I, Page 7 of 9, 8 of 9, and 9 of 9 The toxicity re -opener on page 9 of 9 (Part 1, C 7 ) has been deleted. The re -opener language on pages 7 of 9 and 8 of 9 has been revised to read as follows: Should any test data from either these monitoring requirements or tests performed by the North Carolina Division of Water Quality indicate or predict negative P O Box 29535, Raleigh, North Carolina 27626-0535 Telephone 919-733-7015 FAX 919-733-0719 An Equal Opportunity Affirmative Action Employer 50% recycled/ 10% post -consumer paper } NPDES Permit Issuance Permit No NC0003425 CP&L Roxboro S E Power Plant Page 2 of 2 impacts to the biological integrity of the receiving stream, this permit may be re- opened and modified to include alternate monitoring requirements or limits. • Part II. General Comments CP&L requested the inclusion of a definition for continuous temperature monitoring The Division at this point is not prepared to draft a representative definition However, the Division does recognize that reasonable downtime is acceptable If CP&L would like to submit a definition for continuous temperature monitoring, the Division will review it and (if approved) will keep it in the permit file for the subject CP&L facihty • Part 11, Page 10 of 21 The Division does not agree that upsets should be listed in B 3 as an exception to noncompliance Therefore, no modifications have been made to the permit If any parts, measurement frequencies or sampling requirements contained in this permit are unacceptable to you, you have the right to an adjudicatory hearing upon written request within thirty (30) days following receipt of this letter This request must be in the form of a written petition, conforming to Chapter 150B of the North Carohna General Statutes, and filed with the Office of Administrative Hearings, Post Office Drawer 27447, Raleigh, North Carolina 27611-7447 Unless such demand is made, this decision shall be final and binding Please take notice this permit is not transferable Part II, E 4 addresses the requirements to be followed in case of change in ownership or control of this discharge This permit does not affect the legal requirements to obtain other permits which may be required by the Division of Water Quality or permits required by the Division of Land Resources, Coastal Area Management Act or any other Federal or Local governmental permit that may be required If you have any questions concerning this permit, please contact Mr Jeff Myhra at telephone number (919)733-5083, extension 597 gingl' Signed By David A.
