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 DWR. 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 Wilmington Regional Office supervisor, telephone number [phone],
must be contacted immediately for further instructions regarding any additional follow-up analyses required.
6. 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 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 this attachment.

215.1 to construct, maintain, and/or operate the Disposal System.
4. The Development was created subject to unit ownership in the dwellings units, other improvements and
lands through filing of a Declaration of Unit Ownership (hereinafter DecIaration), pursuant to Chapter
47C of the North Carolina General Statutes.
5. The COMMISSION desires to assure that the Disposal System of the Development is properly
constructed, maintained and operated in accordance with law and permit provisions in order to protect the
quality of the waters of the State and the public interest therein.
NOW, THEREFORE, in consideration of the promises and the benefits to be derived by each of the parties
hereto, the COMMISSION and ASSOCIATION do hereby mutually agree as follows:
1. The ASSOCIATION shall construct the Disposal System and/or make any additions or modifications to
the Disposal System in accordance with the permit and plans and specifications hereafter issued and
approved by the COMMISSION, and shall thereafter properly operate and maintain such systems and
facilities in accordance with applicable permit provisions and law.
2. The ASSOCIATION shall provide in the Declaration and Association Bylaws that the Disposal System

3. The ASSOCIATION shall provide in the Declaration and Association Bylaws that the Disposal System
will be maintained out of the common expenses. In order to assure that there skull be funds readily
available to repair, maintain, or construct the Disposal System beyond the routine operation and
maintenance expenses, the Declaration and Association Bylaws shall provide that a fund be created out of
the common expenses. Such fund shall be separate from the routine maintenance fund allocated ,for the
facility and shall be part of the yearly budget.
