WQ24003 Version 2.0 Shell Version 090204 Page 1 of 7

H. PERFORMANCE STANDARDS
The surface irrigation facilities shall be effectively maintained and operated at all times so that there
is no discharge to the surface waters, nor any contravention of groundwater or surface water
standards. In the event that the facilities fail to perform satisfactorily, including the creation of
nuisance conditions due to improper operation and maintenance, or failure of the irrigation area to
adequately assimilate the wastewater, the Permittee shall take immediate corrective actions including
those actions that may be required by the Division, such as the construction of additional or
replacement wastewater treatment and disposal facilities.
2. The issuance of this permit shall not relieve the Permittee of the responsibility for damages to ground
or surface waters resulting from the operation of this facility.
3. All wells that are constructed for purposes of groundwater monitoring shall be constructed in
accordance with 15A NCAC 02C .0108 (Standards of Construction for Wells Other than Water
Supply) and any other state and local laws and. regulations pertaining to well construction.
4. Effluent limitations shall not exceed those specified in Attachment A.
5. Application rate(s), whether hydraulic, nutrient, or other pollutant shall not exceed those specified in
Attachment B.
The compliance boundary for the disposal system is specified by rules in 15A NCAC 02L,
Groundwater Classifications and Standards. This disposal system was individually permitted on or
after December 30, 1983; therefore, the compliance boundary is established at either 250 feet from
the waste disposal area, or 50 feet within the property boundary, whichever is closest to the waste
disposal area. An exceedance of groundwater standards at or beyond the compliance boundary is
subject to remediation action according to 15A NCAC 02L .0106(d)(2) as well as enforcement
actions in accordance with North Carolina General Statute 143-215.6A through 143-215.6C.
7. The Permittee shall apply for a permit modification prior to any sale or transfer of property that
affects a compliance boundary to establish a new compliance boundary.

constructed within the compliance boundary except as provided by 15A NCAC 02L .0107(g).
9. The 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 action in accordance with 15A NCAC 02L .0106.
10. The facilities permitted herein must be constructed according to the following setbacks:
a. The setbacks for Irrigation sites shall be as follows (all distances in feet):
i. Any habitable residence or place of public assembly under separate ownership
ii. Surface waters:

S. Another method with prior approval by the Aquifer Protection Section Chief
Any method used must meet the following qualifications:
a. A laboratory must be DWQ certified to run any method used.
b. The method used must, at a minimum, include all the constituents listed in Table Vlll of Standard Method 6230D.
C. The method used must provide a PQL of 0.5 pg/L or less that must be supported by laboratory proficiency studies as required by the DWQ Laboratory Certification Unit. Any constituents
detected above the MDL but below the PQL of 0.5 µg/L must be qualified (estimated) and reported.
e. If any volatile organic compounds (VOC) are detected as a result of monitoring as provided in Attachment C, then the Washington Regional Office Aquifer Protection Supervisor, telephone
number [phone]. must be contacted immediately for further instructions regarding any additional follow-up analyses required.
f. If TOC concentrations greater than 10 mg/l are detected in any downgradient monitoring well, additional sampling and analysis must be conducted to identify the individual constituents
comprising this TOC concentration. If the TOC concentration as measured in the background monitor well exceeds 10 mg/l, this concentration will be taken to represent the naturally occurring
TOC concentration. Any exceedances of this naturally occurring'I'OC concentration in the downgradient wells shall be subject to the additional sampling and analysis as described above.
