N. T. Cox Farm
Groundwater Remediation System
Pitt County
Dear Ms. Hardee:
On October 26, 1992, the Division of Environmental Management issued Permit No. WQ0006761
to the N. T. Cox Farm for the construction and operation of the subject groundwater remediation system.
On November 19, 1992, the Division received two Ietters from UTTS/Environmental (UTTS/E) objecting
to some of the conditions and requirements in Permit No. WQ0006761, which was issued on October 26,
1992. As a result of the submitted letters, the Division has evaluated the concerns expressed, has modified
the permit where appropriate, and has given you the opportunity to review a draft permit. A summary of
the objections raised by UTTS/E and the Division's position on those objections is contained below:
Objection 1: UTTS/E requests that condition IV.1 be modified to require that the influent and effluent
samples from the groundwater treatment system be analyzed by EPA Method 8021, which
they stated is equivalent to EPA Method 602 plus Naphthalene.
Response 1: The Division feels that a detection method with a good detection limit for Naphthalene is
needed. This matter has been discussed between UTTS/E and the Division's Groundwater
Section. It has been decided that EPA Method 502.2 will suit both parries' needs.
Condition IV.1 has been modified to require EPA Method 502.2 and to require the analysis
of Naphthalene.
Objection 2: UTTS/E requested that condition IV.1 be modified to require that the influent and effluent
from the Groundwater treatment system be sampled once per week for a month.
Response 2: The Groundwater Section states that the sampling schedule specified in condition IV.1
provides a good break-in period for the equipment and that this schedule results in a
comparable number of samples being collected when compared to the proposal from
UTTS/E. The Groundwater Section states that UTTS/E has agreed to this proposal;
therefore, the sampling schedule proposed in condition IV.1 has not been modified.

Objection 3: UTTS/E requested that condition IV.1 be modified to require that the sampling schedule be
revised to monthly after the initial month.
Response 3: See response 2 above.
Objection 4: UTTS/E requested that condition N.2 be modified to require groundwater monitoring
quarterly.
Respons": The Groundwater Section recommends that the present sampling requirement of twice per
year (in January and July) be retained. They state that this issue has been discussed with
UTTS/E; therefore, the groundwater monitoring schedule has not been modified.
Condition IV.2 has been modified to require the analysis of Naphthalene.
Objection 5: UTTS/E requested that condition IV.2 be modified to require groundwater analysis by EPA
Method 8021.
Response 5: See response 1 above.
Objection 6: UTTS/E stated that quarterly status reports should be performed and submitted to the
Groundwater Section.
Response b: Since the monitoring requirements specified in condition IV.2 were not modified to require
quarterly monitoring, the reporting requirements in condition IV A have not been revised.
Objection 7: UTTS/E requested that they be allowed to visit the site monthly rather than weekly since
they state that a telemetry system will notify them if problems occur.
Response 7: The Division feels that the site must be inspected at least weekly; therefore, condition FV. 10
has not been modified.
In accordance with your previous acceptance (as stated in a letter dated 1/11/93 from
UTTS/Environmental) of the draft permit that was transmitted to you on January 6, 1993, this permit shall
be final and binding and shall be effective from the date of issuance until September 30, 1997, shall void
Permit No. WQ0006761, which was issued on October 26, 1992, and be subject to the conditions and
limitations as specified therein.
If you need additional information concerning this matter, please contact Mr. Randy Jones at 919/
