Division personnel have noticed several typographical errors in your most recently issued
permit. The corrected pages are included with this letter. Please discard the old pages and insert the new
pages A(1), A(2), and A(3) into your permit. The corrections that have been made are listed as follows:
➢ All metals are now expressed as total metals.
➢ The toxicity testing language in section A(3) has been modified. Your WET testing
requirements will not change.
Please note that this permit is not transferable except after notice to the Division. The Division
may require modification or revocation and reissuance of the permit. This permit does not affect the
legal requirements to obtain other permits which may be required by the Division of Water Quality or
permits required by the Division of Land Resources, the Coastal Area Management Act or any other
Federal or Local governmental permit that may be required.
If you have any questions concerning this perinit, please contact Toya Fields at telephone

Permit NC0006351
SUPPLEMENT TO EFFLUENT LIMITATIONS
AND MONITORING REQUIREMENTS
SPECIAL CONDITIONS
A (2). CHRONIC TOXICITY PASS/FAIL PERMIT LIMIT (QUARTERLY)
The effluent discharge shall at no time exhibit observable inhibition of reproduction or significant mortality to
Ceriodaphnia dubia at an effluent concentration of 0.96%.
The permit holder shall perform at a minimum, quarterly monitoring using test procedures outlined in the
"North Carolina Ceriodaphnia Chronic Effluent Bioassay Procedure," Revised February 1998, or subsequent
versions or "North Carolina Phase II Chronic Whole Effluent Toxicity Test Procedure" (Revised -February
1998) or subsequent versions. The tests will be performed during the months of January, April, July, and
October. Effluent sampling for this testing shall be performed at the NPDES permitted finaleffluent
discharge below all treatment processes.
If the test procedure performed as the first test of any single quarter results in a failure or ChV below the
permit limit, then multiple -concentration testing shall be performed at a minimum, in each of the two
following months as described in "North Carolina Phase II Chronic Whole Effluent Toxicity Test Procedure"
(Revised -February 1998) or subsequent versions.
The chronic value for multiple concentration tests will be determined using the geometric mean of the highest
concentration having no detectable impairment of reproduction or survival and the lowest concentration that
does have a detectable impairment of reproduction or survival. The definition of "detectable impairment,"
collection methods, exposure regimes, and further statistical methods are specified in the "North Carolina
Phase II Chronic Whole Effluent Toxicity Test Procedure" (Revised -February 1998) or subsequent versions.
All toxicity testing results required as part of this permit condition will be entered on the Effluent Discharge Monitoring
Form (MR-1) for the months in which tests were performed, using the parameter code TGP3B for the pass/fail:results
and THP3B for the Chronic Value. Additionally, DWQ Form AT-3 (original) is to be sent to the following address:
Attention: North Carolina Division of Water Quality
Environmental Sciences Section
1621 Mail Service Center
Raleigh, North Carolina 27699-1621
Completed Aquatic Toxicity Test Forms shall be filed with the Environmental Sciences Section no later than 30
days after the end of the reporting period for which the report is made.
Test data shall be complete, accurate, include all supporting chemical/physical measurements and all
concentration/response data, and be certified by laboratory supervisor and ORC or approved designate
signature. Total residual chlorine of the effluent toxicity sample must be measured and reported if
chlorine is employed for disinfection of the waste stream.
Should there be no discharge of flow from the facility during a month in which toxicity monitoring is
required, the permittee will complete the information located at the top of the aquatic toxicity (AT) test form
indicating the facility name, permit number, pipe number, county, and the month/year of the report with the
notation of "No Flow" in the comment area of the form. The report shall be submitted to the Environmental
Sciences Section at the address cited above.
Should the permittee fail to monitor during a month in which toxicity monitoring is required, monitoring will
be required during the following month.
Should any test data from this monitoring requirement or tests performed by the North Carolina Division of
Water Quality indicate potential impacts to the receiving stream, this permit may be re -opened and modified
to include alternate monitoring requirements or limits.

Permit NC0006351
NOTE: Failure to achieve test conditions as specified in the cited document, such as minimum control
organism survival, minimum control organism reproduction, and appropriate environmental controls, shall
constitute an invalid test and will require immediate follow-up testing to be completed no later than the last
day of the month following the month of the initial monitoring.
SUPPLEMENT TO EFFLUENT LIMITATIONS
AND MONITORING REQUIREMENTS
SPECIAL CONDITIONS (Continued)
A (3). Groundwater Monitoring Requirements
Monitoring wells 1, 4, 5, and 6 shall be sampled semi-annually in conjunction with semi-annual RCRA post
closure permit sampling for the following parameters:
NO3 Sulfate
Calcium Chromium
Magnesium Zinc
Iron Arsenic
Manganese Total Dissolved Solids
pH Water Levels
Chloride Specific Conductance
The measurement of water levels must be made prior to sampling for the remaining parameters. The depth
to water in each well shall be measured from the surveyed point on the top of the casing.
Separate sampling is not required for those parameters included in the RCRA post closure permit
groundwater monitoring requirements and the results of the RCRA permit sampling may be submitted in
fulfilment of this permit requirement for those parameters. Analysis for parameters contained herein but
not included in the RCRA permit should be conducted simultaneously with the RCRA mandated analysis
and all results should be subrnitted simultaneously.
The results of the sampling and analysis shall be sent to the Aquifer Protection Section, 1636 Mail Service
Center, Raleigh, NC 27699-1636 on Form GW-59 [Compliance Monitoring Report Form] within 60 days of
each sampling event.
Any additional groundwater quality monitoring, as deemed necessary by the Division, shall be provided.
The COMPLIANCE BOUNDARY for the disposal system is specified by regulations in 15A NCAC 2L,
Groundwater Classifications and Standards. The Compliance Boundary for the disposal system
constructed prior to December 31, 1983 is established at either (1) 500 feet from the waste disposal area, or
(2) at the property boundary, whichever is closest to the waste disposal area. An exceedance of
Groundwater Quality Standards at or beyond the Compliance Boundary is subject to immediate remedial
action in addition to the penalty provisions applicable under General Statute 143-215.6A (a) (1).
In accordance with 15A NCAC 2L, a REVIEW BOUNDARY is established around the disposal systems
midway between the Compliance Boundary and the perimeter of the waste disposal area. Any exceedance
of standards at the Review Boundary shall require remedial action on the part of the Permittee.
