02L .0107(b). This disposal system was individually permitted on or after December 30, 1983;
therefore, the compliance boundary is established at either 250 feet from the effluent disposal area, or
50 feet within the property boundary, whichever is closest to the effluent disposal area. An
exceedance of groundwater standards at or beyond the compliance boundary is subject to remediation
action according to 15A NCAC 02L .010£(d)(2) as well as enforcement actions in accordance with
North Carolina General Statute 143-215.6A through 143-215.6C.
8. In accordance with 15A NCAC 02L .0108, the review boundary is established midway between the
compliance boundary and the effluent disposal area. Any exceedance of groundwater standards at the
review boundary shall require action in accordance with 15A NCAC 02L .0106.

Onslow County Register of Deeds an easement running with the land containing the following items:
a. A notice of the permit and number or other description as allowed in 15A NCAC 02L .0107(f)(1);
b. Prohibits construction and operation of water supply wells within the compliance boundary; and
c. Reserves the right of the Permittee or the State to enter the property within the compliance
boundary for purposes related to the permit.
The Director may terminate the easement when its purpose has been fulfilled or is no longer needed.

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 ofthe casing. The measurement
of pi I shall be made after purging and prior to sampling for the remaining parameters.
3. 'tile 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 measuring points (top
of casing) of all monitoring wells shall be surveyed relative to a conuuon datum.
4. Volatile Organic Compounds (VOC) - In November only. analyze by one of the following methods:
n. Standard Method 6230I). PQL at 0.5 µg/l, or less
b_ Standard Method 62101), PQL at 0.5 ttg/L or less
C. EPA Method $021, Low Concentration, PQL at 0.5 pg/t, or less
d. CPA Method 8260, Low Concentration, PQL at 0.5 Irg/L or less
e_ Another method vdth prior approval by the Aquifer Protection Section Chief
Any method used must meet the following qualifications:
a. A laboratory must be DWQ certified to nun any method used.
b_ The nhethod used inust. at a minimum, include all the constituents listed in Tab[e Vill of Standard Method 62301).
e. 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 [he MIX but below the I'QL of 0.5 µg/1, must Ire qualified (estimated) and reported.
5, Wally volatile organic compounds (VOC) are detected as a result of monitoring as provided in Altachnhent C. [lien the Wilmington Regional 01'lice Aquifer Protection Srlpei-visor, telephone
number (910) 796-72 [5. must be contacted immediately for lilrther instructions regarding any additional follow-up analyses required.
6If ft)C concentrations greater than 10 Ins/l are detected in any downgradlent monitoring well, additional sampling and analysis must be conducted to mdClitlfy the individual constituents
comprising this TOC concentration. If the TOC concentration as measured in the background monitor well exceeds 10 mg/I. this concentration will he taken to represent the naturally occurring
TOC concentration. Am• exceedances of [his naturally occurrine TOC concentration in the downeradient wells shall be subiect to the additional samnlino and analvgfs at deccrihed nhnve
7. Monitoring wells shall he reported consistent «ith the nomenclature and location birornhnflon provided in Figure I and this atlacliment.
