therein. Please pay particular attention to the monitoring requirements in this permit. Failure to establish
an adequate system for collecting and maintaining the required operational information will result in
future compliance problems.
If any parts, requirements, or limitations contained in this permit are unacceptable, you have the
right to request an adjudicatory hearing upon written request within 30 days following receipt of this
permit. This request must be in the form of a written petition, conforming to Chapter 150B of the North

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.

1. 3 X year monitoring shall be conducted in March, July & November; Annual monitoring shall be conducted every November.
2. The measurement of water levels shall be made prior to purging the wells. The depth to water in each well shall be measured from the surveyed point on the top of the casing. The measurement
of pH shall be made after purging and prior to sampling for the remaining parameters.
3. The measuring points (top of well casing) of all monitoring wells shall be surveyed to provide the relative elevation of the measuring point for each monitoring well. The mcasuring points (top
of casing) of all monitoring wells shall be surveyed relative to a common datum.
4. Volatile Organic Compounds (VOC) - In November only, analyze by one of the following methods:
a. Standard Method 6230D, PQL at 0.5 µg/L or less
b. Standard Method 621 OD, PQL at 0.5 µg/L or less
C. EPA Method 8021, Low Concentration, PQL at 0.5 }rg[L or less
d. EPA Method 8260, Low Concentration, PQL at 0.5 pg/L or less
e. Aoather 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 V11.1 of Standard Method 6230D.
c. `the method used must provide a PQL of 0.5 µg/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.
5. If any volatile organic compounds (VOC) are detected as a result of monitoring as provided in Attachment C, then the Washington Regional Off -ice Aquifer Protection Supervisor, telephone
number [phone], must be contacted immediately for further instructions regarding any additional follow-up analyses required.
WC 0009772 Version 1..2 Attachment C Page I of 2

6. If TOC concentrations greater than 10 mg/1 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 TOC concentration in the downgradient wells shall be subject to the additional sampling and analysis as described above.
7. Monitoring wells shall be reported consistent with the nomenclature and location information provided in Figure 1 and this attachment.
