Subject: Request for Variance - NORTH CAROLINA WELL CONSTRUCTION
STANDARDS Rules 15A NCAC 2C .0213 (d)(1)(A), 2C .0213(c)(1)(E), and
2C .0213(c)(1)(D), Additional Criteria and Standards Applicable to Class V -
Weil Operation; Richard's Exxon, Martin County, North Carolina
Dear Mr. Frank Williams:
This is in response to the letter of February 13, 1996, from Mr.David Giachini, of
ENSCI Engineering Group, P.A., requesting approval of a variance from the referenced Rules
for Injection Wells IW-1 and iW-2. Rule 2C .0213(d)(I)(A) requires that injection wet
casing be installed which extends at least 12 inches above land surface. You stated in your
letter that the subject wells could not be constructed in accordance with that Rule when
completed in traffic areas.
Factors that would act to mitigate any potential problems which could adversely affect
human health and/or the effective operation of this well, because of not meeting the regulatory
requirements, are as follows:
The proposed flush mount construction will provide for adequate protection of
the wet head.
2_ The proposed flush mount construction will provide an adequate seal and
prevent contamination of the well from surface runoff.
Additionally, Rule 2C .0213(1)(E) requires a minimum horizontal distance of 100 feet
between any sewage disposal facility such as a septic tank and drain field and an injection well.
Rule 2C .0213(1)(D) requires a minimum horizontal distance of 50 feet between any water-
tight sewage collection facility (sewer line). A review of the CAP indicates that the subject
wells could not be sited in accordance with that Rule because of the property size and the
necessity of the closed -loop operation of the groundwater remediation system using injection
wells.

Richard's Exxon
Variance to 15A NCAC 2C .0213
Page 2
Factors that would act to mitigate any potential problems which could adversely affect
human health and/or the effective operation of this well, because of not meeting the regulatory
requirements, are as follows --
I . The amount of effluent from the drain field should be relatively small.
2. The injection system is expected to mound creating a gradient that would
effectively prohibit any drain field effluent from interfering with the
groundwater remediation system.
Based on my review of the available information and recommendations by our staff, it is my finding that the combination of factors specified above are sufficient to satisfy the
conditions for approval of variances from 15A NCAC 2C .0213 (d)(1)(A), from 15A NCAC
2C .0213 (c)(1)(E), and from 15A NCAC 2C .0213 (c)(1)(D), as defined in 15A NCAC 2C
.0118. On that basis, and with the additional requirement that you notify the Washington
Regional Off ce at [phone], at least 24 hours before any well construction activities
are begun, the requested variances from Rule 15A NCAC 2C .0213 (d)(1)(A), from 15A
NCAC 2C .0213 (c)(1)(E), and from Rule 15A NCAC 2C .0213 (c)(1)(D) are hereby granted,
The granting of this variance does not affect any of the other requirements of the
WELL CONSTRUCTION STANDARDS or of the requirements of any other applicable laws
or rules. The granting of this variance does not constitute the approval of any
application for a non -discharge permit associated with a groundwater rernediation
project.
