DANIEL SMITH Director Aqua North Carolina Inc. 2020 Mackenan Court Attn: Mr. Shannon Becker Cary, NC 27511 Dear Mr. Shannon Becker: NORTH CAROLINA Environmental Quality October 22, 2021 Re: Preliminary Well Site Approval THE CAPE MASTER SYSTEM Water System No.: NC0465199 New Hanover County On October 20, 2021, I met with Joel Mingus and conducted a preliminary investigation of the proposed well sites listed below and shown on the attached drawings. The proposed wells have been assigned Water System Facility (WSF) Identification Numbers and Sampling Point Codes as indicated below. WSF ID No. Sampling Point Code Description of Well Site Preliminary Latitude and Longitude W14 R14 —200' north of Motts Forest Rd. —450' east of Motts Village Rd. 15' northeast of the existing "Well #11_Motts Landing" Facility ID No. W 11 34° 07' 34.3541" N, 77° 54' 31.5934" W W15 R15 —200' north of Motts Forest Rd. —450' east of Motts Village Rd. 15' southwest of the existing "Well #11_Motts Landing" Facility ID No. W 11 34° 07' 34.3309" N, 77° 54' 31.8441" W W16 R16 20' southeast of the existing "WELL #10 - WINDSWEPT WELL" Facility ID No. W10 34° 04' 36.83521" N, 77° 54' 25.77815" W This letter is provided by Public Water Supply (PWS) Section, in accordance with rule .0305(b) of the Rules Governing Public Water Systems (15A NCAC 18 C), to provide permission to drill wells at the listed sites in order to establish water quality and quantity and suitability of the wells as a source for a public water system. In addition, this "preliminary well site approval" is to acknowledge that according to the information and documentation provided, we understand that the proposed wells are located on NORM CAAOLiry A DE flspartmenl of Environmental finality North Carolina Department of Environmental Quality I Division of Water Resources Wilmington Regional Office 1127 Cardinal Drive Extension I Wilmington, North Carolina 28405 910.796.7215 lots so that the area within 100 feet of the wells is/will be owned or controlled by the person supplying the water and that the supplier of water will protect the well lots from potential sources of pollution and construct landscape features for drainage and diversion of pollution as required in rule .0203(1). In addition, we understand that you have determined that the proposed well locations satisfy the minimum horizontal separation distances specified in rule .0203 (2) and summarized in the following table: Distance (in feet) Potential Source of Pollution 100 • • • • • From any sanitary sewage disposal system, sewer, or sewer pipe (unless sewer is constructed of water main materials and joints, in which the sewer pipe shall be at least 50 feet from the well. From buildings, mobile homes, permanent structures, animal houses or lots, cultivated areas to which chemicals are applied. From surface water. From a chemical or petroleum fuel underground storage tank with secondary containment. From any other potential source of pollution not listed in this table. 200 • From a subsurface sanitary sewage treatment and disposal system designed for 3,000 or more gallons of wastewater a day, unless your well water source is a confined aquifer. 300 • From any cemetery or burial ground. 500 • • • • From a septage disposal site. From a chemical or petroleum fuel underground storage tank without secondary containment. From the boundary of a ground water contamination area. From a sanitary landfill or non -permitted non -hazardous solid waste disposal site. 1,000 • From a hazardous waste disposal site or in any location which conflicts with the North Carolina Hazardous Waste Management Rules cited in NCAC 13A. We also understand that the owner will ensure that the lots are graded or sloped so that surface water is diverted away from the wellheads and the wells shall not have greater than a 1 percent chance of flooding in accordance with 15A NCAC 18C .0203(a)(4). PWS Section "Authorization to Construct" and "Final Approval" Subsequent to well drilling and evaluating water quality and quantity (e.g., collecting and analyzing samples and performing a 24-hour well drawdown test) the owner must submit an "Application for Approval of Engineering Plans and Specifications For Water Supply Systems" to document proposed well completion (e.g., selected pump, wellhead and well house details) and associated transmission lines, treatment and/or storage facilities and other critical information about the public water system. In accordance with rule .0305(a) no construction shall be undertaken until the PWS Section issues an "Authorization to Construct" letter. In addition, in accordance with .0309(a) the new wells and all associated treatment, storage or transmission/distributions lines shall not be placed into service until the PWS Section has issued a "Final Approval." These steps are described in the Engineering Planning and Development Guidance Document available at http://files.nc.gov/ncdeq/Water%20Resources/files/pws/planreview/EPD Guidance _July2019.pd f D_E NORTH CAROI INA geparhnenl of Environmentalquau\ r North Carolina Department of Environmental Quality I Division of Water Resources Wilmington Regional Office 1127 Cardinal Drive Extension I Wilmington, North Carolina 28405 910.796.7215 Be aware that plans, specifications and reports for the new wells must be certified by a Professional Engineer. Therefore, it is recommended that a Professional Engineer or Licensed Geologist (or their designated representative) experienced in the construction of water supply wells, conduct on -site monitoring of well construction. At a minimum, certain critical phases of well construction such as installation and grouting of casing should be monitored. In many situations it may be necessary to go beyond the minimum requirements in order to protect the public health and ground water resources. Other Agency Approvals Required This PWS Section "preliminary well site approval" letter does not address other agency applicable rules and requirements pertaining to well construction and registration. Local county well construction rules and ordinances may include additional requirements. Well construction must meet the standards specified in the Well Construction Standards (15A NCAC 2C). Be aware that these rules require a permit to be obtained from the Water Quality Regional Operations Section of the Division of Water Resources before the well is constructed if it is anticipated that the new well will be part of a water system with a design capacity of 100,000 gallons per day or greater. In addition, these rules require that wells be constructed by a properly certified well driller.
