Mr. Wilson,
Thanks for speaking with me yesterday. I did pick up the hard copy of the application and confirmed there is missing
information. The rules for geothermal aqueous closed‐loop wells (15A NCAC 02C .0222) require the following
information to be included with the application:
a scaled, site‐specific map showing the following:
(A) any water supply well and surface water body; septic system including drainfield, waste application area, and
repair area; and any other potential sources of contamination listed in Subparagraph (e)(5) of this Rule within
250 feet of the proposed injection wells (see horizontal setback distancse in next bullet item;
(B) property boundaries within 250 feet of the parcel where the proposed wells are located; and
(C) an arrow orienting the site to one of the cardinal directions.
The horizontal separation between the geothermal aqueous closed‐loop well and potential sources of
groundwater contamination that exist at the time the wells are constructed shall be no less than as follows:
(A) Building perimeters, including any attached structures for which a building permit is required, such as
garages, patios, or decks, regardless of foundation construction type ‐ 15 feet
(B) Septic systems, including drainfield, waste application area, and repair area ‐ 50 feet
(C) Industrial or municipal sewage or liquid waste collection or transmission sewer mains constructed to
water main standards as stated in the American Water Works Association (AWWA) Standards C600 and/or
C900 ‐ 15 feet
(D) Water‐tight sewer lateral lines from a residence or other non‐public system to a sewer main or other
wastewater disposal system ‐ 15 feet
(E) Other industrial or municipal sewage or liquid waste collection or transmission sewer mains ‐ 25 feet
(F) Chemical or petroleum fuel underground storage tank systems regulated under 15A NCAC 02N with
secondary containment ‐ 50 feet
(G) Chemical or petroleum fuel underground storage tank systems regulated under 15A NCAC 02N without
secondary containment ‐ 100 feet
(H) Above ground or underground storage tanks that contain petroleum fuels used for heating
equipment, boilers, or furnaces, except for tanks used solely for storage of propane, natural gas, or
liquefied petroleum gas ‐ 50 feet
(I) Land‐based or subsurface waste storage or disposal systems ‐ 50 feet
(J) Gravesites ‐ 50 feet
(K) Any other potential sources of contamination ‐ 50 feet
Plans and specifications (diagram) of the surface and subsurface construction details of the system.
The heating and cooling system installation contractor's name and certification number, address, email address
(if available), and telephone number;

Please submit the remaining information as soon as you are able and I will complete my review of the permit
application. Please feel free to contact me if you have questions or concerns. You can reach me by email or by cell at
