Cary, North Carolina 27518 ALAN R. KEITH, P.E. Telephone (919) 467-9972 — Fax (919) 467-5327 June 22, 2020 Mr. Nathaniel Thornburg Branch Chief Division of Water Resources- Non -Discharge Branch 1617 Mail Service Center Raleigh, NC 27699-1617 [Submitted via email to: Thornburg, Nathaniel nathaniel.thornburg(ancdenr.aov] Re: Minor Permit Modification Request Chapel Ridge Effluent Storage Pond Permit No. WQ0022870 Dear Mr. Thornburg: Please find attached one signed form RWNC 06-16, plans for the addition of two 5 HP floating aerators to the effluent storage pond for the Chapel Ridge Wastewater Treatment Plant (aerator specifications are included on sheet 2 of the plans), and a copy of the latest issue of Permit No. WQ0022870. On behalf of the permittee, Aqua North Carolina, Inc., we are requesting a minor modification of the referenced permit to allow the installation of the floating aerators. The aerators are proposed in response to odor concerns raised by some of the residents of the Chapel Ridge community. The treated reclaimed water is irrigated on common areas and the golf course within Chapel Ridge; the irrigated waters have been the source of the odor concerns. It is our opinion that any objectionable odors associated with the irrigated waters could be due to the intake pipe for the irrigation system being located at the bottom of the storage pond, thus making it likely that water is withdrawn from the most oxygen -depleted zone of the pond. The bottom of ponds and lakes typically have anaerobic bacteria present due to the lack of dissolved oxygen; as these bacteria decompose organic matter that has settled to the bottom of the pond, a byproduct of their activity is the production of compounds containing sulfur. If these compounds are exposed to air, as is possible through irrigation, the sulfur compounds can produce objectionable odors. Mr. Nathaniel Thornburg June 22, 2020 Page 2 of 2 In an effort to address this potential problem, two 5 horsepower floating aerators are proposed for the storage pond. The aerators will be located in the vicinity of the irrigation intake pipe, with the goal being to create aerobic conditions for that section of the pond and to minimize the possibility of anaerobically produced sulfur compounds being withdrawn from the pond. Due to the maximum depth possible in the pond, the aerators are proposed to have draft tubes, to extend their mixing and oxygenation effects deeper into the pond. The attached plans show the effective radii of mixing and oxygenation of the aerators, based on the manufacturer's data. The oxygenated volume in the pond could be equivalent to 4 to 10 days of irrigation flow, depending upon the depth of the pond and the volume of irrigation water applied. Given this project does not propose to alter the permitted flow. the treatment unit processes, or the irrigation zones, only Parts I and II of the attached RWNC 06-16 were completed. Please advise if you require any other information for this minor permit modification request, or if you require paper copies of the attached files. Thank you for your assistance with this project.

Failure to comply with the conditions and limitations contained herein may subject the Permittee to an enforcement action by the Division in accordance with North Carolina General Statutes 143-215.6A to 143-215.6C. [G.S. 143-215.6A to 143-215.6C] 2. This permit is effective only with respect to the nature and volume of wastes described in the permit application, Division approved plans and specifications, and other supporting documentation. No variances to applicable rules governing the construction or operation of the permitted facilities are granted, unless specifically requested and approved in this permit pursuant to 15A NCAC 02T .0105(n). [G. S. 142-215.1 ] 3. Pursuant to the flow reduction request approved November 29, 2004, the Division accepts the data - based design flow rate of 250 gallons per day per residence (GPD/residence) for the users served by this facility. Regardless of the adjusted daily wastewater design flow rate, at no time shall wastewater flows exceed the limits defined in this permit for the subject facility, or exceed the sewer capacity downstream of any new sewer extension or service connection(s). The Permittee shall report the actual (i.e., measured) monthly average amount of wastewater flow contributed per unit (GPD/residence) for the 12 months prior to permit renewal. If any of these actual monthly averages are within 20% of the approved value, the Permittee shall re-evaluate the approved value using the methodology applied to determine the approved flow rate of 250 GPD/residence, and submit this information within 18 months. The Division may change the daily wastewater design flow rate for connections to the system at that time, and upon each renewal cycle, pending an evaluation of the submitted flow information. [ 15A NCAC 02T .0114(f)] 4. The Permittee shall retain the Division's written approval of any authorized adjusted daily design flow rate for the life of the facility, and shall transfer said written approval to any future Permittee.

The measurement of water levels shall be made prior to purging the wells. The depth to water in each well shall be measured from the surveyed point on the top of the casing. The measurement of pH shall be made after purging and prior to sampling for the remaining parameters. 3. The measuring points (top of well casing) of all monitoring wells shall be surveyed to provide the relative elevation of the measuring point for each monitoring well. The measuring points (top of casing) of all monitoring wells shall be surveyed relative to a common datum. 4. If TOC concentrations greater than 10 mg/L are detected in any downgradient monitoring well, additional sampling and analysis must be conducted to identify the individual constituents comprising this TOC concentration. If the TOC concentration as measured in the background monitor well exceeds 10 mg/L, this concentration will be taken to represent the naturally occurring TOC concentration. Any exceedances of this naturally occurring TOC concentration in the downgradient wells shall be subject to the additional sampling and analysis as described above. 5. Monitoring wells shall be reported consistent with the nomenclature and location information provided in Exhibit 1 and this attachment.
