RE: Well Variance Permit #WV0300114
Variance Request to Rule 15A NCAC 2C .0107(a)(2)(E) —
Separation distance between a well and other sewage and
liquid waste collection or transfer facility
Irrigation Well
7907 Skye Lochs Drive, Waxhaw
Union County
On July 29, 2020, the Mooresville Regional Office received the completed written request for a variance to the well
construction rules, specifically rule 15A NCAC 2C.0107 (a)(2)(E), which specifies a 100-foot separation from "other
sewage and liquid -wastewater collection or transfer facility." The variance request is for the construction of an
irrigation water supply well on Skye Lochs Drive, Waxhaw, Union County.
The existing sanitary sewer line, located along the greenway at the back of the property on Skye Lochs Drive, along
with site conditions, limit the well location at the property. In order to provide protection for the groundwater
resource, the new well shall be sited as shown on the submitted map at approximately 65 feet from the Skye Lochs
Drive Drive sewer line and 65 feet from the sewer line. The well shall not be located any closer than 50 feet from
the referenced sanitary sewer line. Based upon the information that has been submitted, a variance to the above -
cited rule is granted. The variance will be effective from the date issued until July 31, 2021. Since the well will not
meet the regulatory requirements, the following minimum additional construction requirements will be necessary
to mitigate any potential problems that could affect public health, the ground water resource and/or the well's
effective operation:
Galvanized steel casing with drive shoe shall be used, or PVC casing may be used if fitted with
appropriate shoe.
The casing shall extend into consolidated bedrock in accordance with the following table:
Depth to Consolidated Bedrock
Minimum Depth of Casing
Less than 50 feet
15 feet into bedrock
50 to 100 feet
10 feet into bedrock
More than 100 feet
5 feet into bedrock
The entire length of the casing shall be grouted. A drill bit that is at least 4 inches greater than the
outside diameter of the casing shall be used to drill the cased portion of the well. Grout shall be
installed using a pump and tremmie pipe. The annular space to be grouted shall be free of
obstructions; if not, the grout must be placed to the maximum achievable depth of the annular space

and a well liner with packer must be installed 10 feet below the casing and fully grouted. The final
construction method shall be shown on the GW-1 Well Construction Record
4. The well shall be used for irrigation purposes only and shall not be used as a potable water
supply.
5. The well shall not be plumbed into connection with municipal water currently serving the
property.
6. The well driller shall be certified by the North Carolina Well Contractor Certification
Commission as required by General Statutes 87-98.4, Title 15A NCAC 27.0101 and .0110.
7. The well shall be located approximately as shown on the provided map. The well is to be set
in a location no closer than 50 feet to the existing sanitary sewer.
It is my finding that the factors specified above are sufficient to satisfy the conditions for approval of a
variance as defined in 15A NCAC 2C.0118. A copy of this variance shall be attached to the required Well
Construction Record (GW-1). The granting of this variance is for the location of the well only, and in no
way relieves the owner or agent from other requirements of the North Carolina Well Construction
Standards, or any other applicable law, rule or regulation that may be regulated by other agencies. If
you are dissatisfied with this decision, you may commence a contested case by filing a petition under
G.S. 150-23 within sixty (60) days after receipt of the decision.
If you have any questions regarding this variance, please contact Edward Watson at 704-663-1699 ext.
2198 or by email at [e-mail].
Sincerely,
