The proposed well has been assigned a Water System Facility (WSF) Identification Number and Sampling Point Code as indicated below. WSF ID No. Sampling Point Code Description of Well Site Preliminary Latitude and Lon itude 100' radius around the proposed Well # 2 location approximately 34.9121290 W02 RW2 700' NNW of the intersection of Bynum Ave. and First Street, -77.2301960 Maysville, NC. This letter is provided by the Public Water Supply (PWS) Section, in accordance with Rule .0305(b) of the Rules Governing Public Water Systems (15A NCAC 18C), to provide permission to drill a well at the listed site in order to establish the quality and quantity of water and the suitability of the well as a source for a public water system. The orouosed well must be drilled within 24 months of the date of this letter. If not drilled within this 24-month period, this Preliminary Well Site Approval letter is void and permission to drill the well is no longer valid. To regain permission to drill the well, PWS Section staff must revisit the proposed site to conduct an investigation and issue a new preliminary well site approval letter before the well may be drilled. In addition, this "Preliminary Well Site Approval" is to acknowledge that according to the information and documentation provided, we understand that the proposed well is located on a lot so that the area within 100 feet of the well will be owned or controlled by the person supplying the water and that the supplier of water will protect the well lot from potential sources of pollution and construct landscape features for drainage and diversion of pollution as required in 15ANCAC 18C .0203(a)(1). The Town of Maysville does not currently own or control the area within a 100-foot radius of proposed Well # 2 (W02). Preliminary well site approval to drill Well # 2 is given with the provision that the Town will own or control the area within a 100-foot radius of the well, as required in rule .0203(1), before the wells can receive final approval. Final approval to use the well will not be given if the Town fails to obtain ownership or control of the area within a 100-foot radius of the well. Furthermore, we understand that Ethan Gartin, PE (TRC engineering firm), per letter/email dated February 9, 2023, has determined that the proposed well location satisfies the minimum horizontal separation distances specified in 15A NCAC 18C .0203(a)(2) and summarized in the following table: Distance (in Potential Source of Pollution feet 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 lot is graded or sloped so that surface water is diverted away from the wellhead and that the well shall not have greater than a 1 percent annual 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 (i.e., 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 (i.e., 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 15A NCAC 18C .0305(a) no construction shall be undertaken until the PWS Section issues an "Authorization to Construct" letter. In addition, in accordance with 15A NCAC 18C .0309(a) the new well 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 https://files.nc.gov/nedeq/Water%2OResources/files/ows/planreview/EPD Guidance July20l9.p df Be aware that plans, specifications and reports for the new Well 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.
