IVEY, TowN ADMDUSTRATOR TOWN OF OCEAN ISLE BEACH 3 WEST T�In2I7 STREET OCEAN ISLE BEACH, NORTH CAROLINA 28469-7506 Dear Ms. Ivey: IF?e IT NCDENR NORTH CAROL.INA DEPARTMENT OF ENVIRONMENT AND NATURAL RESOURCES Subject: Permit No. WQ0006085 Correction Town of Ocean Isle Beach Town of Ocean Isle Beach Wastewater Treatment Plant Upgrade Wastewater Treatment and Spray Irrigation / Reclaimed Water Utilization System Brunswick County In accordance with a telephone request received on August 20, 2001 from Mr. J.F. Boney, acting on the Town of Ocean Isle Beach's (Town) behalf, we are forwarding herewith a corrected Page 11 of Permit No. WQ0006085, issued August 13, 2001, for the subject wastewater treatment and spray irrigation/reclaimed water utilization systern. The following correction has been made to the pen- nit- 1. Condition IV. 1. of the permit requires that irrigation of wastewater effluent or reclaimed water shall not be performed when the separation between the seasonal high water table and the land surface is less than three feet. During adjudicatory negotiations following a 1997 permitting action, the Town and the Division of Water Quality (Division) agreed that the phrase "seasonal high" would be stricken from this condition. At that time, the Division provided guidance regarding this condition as follows: "[t]he intent of the condition is to prohibit the spray irrigation of wastewater onto the land when the actual water table is less than three feet below the land surface [and] not when evidence of a seasonal high water table is present within three feet of the Iand surface." In this most recent permitting action, the Division mistakenly included the "seasonal high" phrase in this condition once again. With this correction, the language of this condition is being amended to rectify this oversight by reflecting the language agreed to by the Town and the Division in 1997. Please replace Page 1.1 with the corrected Page 11 into Permit No. WQ0006085, issued August 13, 2001. 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 any additional information concerning this matter, please contact Ms. Shannon Mohr Thornburg at (919) 733-5083, bxtension 353.

Three copies of all reclaimed water monitoring data, as specified in Condition III. 2. and Condition III. 5., shall be submitted on Form NDMR-1 on or before the last day of the month following the monitoring/sampling month. All monitoring and reporting forms shall be submitted to the following address: NC Division of Water Quality Water Quality Section Non -Discharge Compliance/Enforcement Unit 1617 Mail Service Center Raleigh, North Carolina 27699-1617 8. Noncompliance Notification: The Permittee shall report by telephone to the Wilmington Regional Office, telephone number (910) 395-3900, as soon as possible, but in no case more than 24 hours or on the next working day following the occurrence or first knowledge of the occurrence of any of the following: a. Any occurrence at the facilities that results in the treatment of significant amounts of wastes which are abnormal in quantity or characteristic, such as the dumping of the contents of a sludge digester; the known passage of a slug of hazardous substance through the facility; or any other unusual circumstances. b. Any process unit failure, due to known or unknown reasons, that render the facilities incapable of adequate wastewater treatment, such as mechanical or electrical failures of pumps; aerators; compressors; etc. c. Any failure of the facilities that results in a bypass directly to receiving waters without treatment of all or any portion of the influent to the facilities. d. Any time that self -monitoring information indicates that the facilities have gone out of compliance with its permit limitations. Persons reporting such occurrences by telephone shall also file a written report in letterform within five days following first knowledge of the occurrence. This report shall outline the actions taken or proposed to ensure that the problem does not recur. IV. GROUNDWATER REQUIREMENTS No irrigation of wastewater effluent/reclaimed water on the spray irrigation/reclaimed water utilization facilities shall be undertaken when the water table is less than three feet below the land surface. 2. Until the existing spray irrigation facilities are modified such that they receive wastewater effluent meeting the reclaimed water quality criteria only (i.e., following the Phase III construction), the six existing groundwater monitoring wells (i.e., MWA, MW-2, MW-3, MW-4, MW-5, and MW-6) shall be sampled every March, July, and November for the following parameters: PH Total Organic Carbon (TOC) Total Ammonia -Nitrogen (NH3-N) Water Level If TOC concentrations greater than 10 milligrams per liter are detected in any downgradient groundwater monitoring well, additional groundwater sampling and analysis shall be conducted to identify the individual constituents comprising the TOC concentration. If the TOC concentration in the background (i.e., upgradient) groundwater monitoring well exceeds 10 milligrams per liter, this concentration shall be taken to represent the naturally -occurring TOC concentration in the groundwater. Any exceedance of this naturally -occurring TOC concentration in downgradient wells shall be subject to additional groundwater sampling and analysis as described above. II
