a. A laboratory must he DWQ certified to run any method used.
b. The method used must at a minimum. include all the constituents listed in I -able Vill of Standard Method 62301).
c. I he method used must provide a PQL of 0.5 Irg/L or less that must be supported by laboratory proficiency studies as required by the DNYQ Laboratory Certification Unit. Any constituents

number [phone]. must be contacted immediately for further instructions regarding any additional follow-up analyses required.
6. If TO(' concentrations greater than 10 mg/I 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'I_ this concentration will be taken to represent the naturally occurring
TO(' concentration. Air,, exceedances of this naturally occurring TOC concentration in the downgradient wells shall he subject to the additional sampling and analysis as described above_

'Ta V1 v a r S 2-0 t Ca, by and between the North Carolina Environmental Management
Commission, .an agency of the State of North Carolina, hereinafter known as the COMMISSION; and
ca:, o wy7 e_ c s Ascm non -profit corporation organized
and existing under and by virtue of the laws of the State of North Carolina, hereinafter known as the
ASSOCIATION.
WITNESSETH:
The ASSOCIATION was formed for the purpose, among others, of handling the property, affairs and
business of the development known as D e-, Y\-e -� e zv'L R -- �/ ; t t OL S
(hereinafter the Development); of operating, maintaining, re -constructing and repairing the common
elements of the lands and improvements subject to unit ownership, including the wastewater collection
system with pumps, wastewater treatment works, and/or disposal facilities (hereinafter Disposal System);
and of collecting.dues and assessment to provide funds for such operation, maintenance, re -construction
and repair.
2, The ASSOCIATION desires, to construct .and/or operate a Disposal System to provide sanitary sewage
disposal to serve the Development on said lands.
The ASSOCIATION has applied to the COMMISSION for the issuance of a permit pursuant to G.S. I43-
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 Declaration), 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 T. _Zloi, 3,� i;1f_I_ � �, �a,�:.,<;1 t'c, ic,4
that the Disposal System and appurtenances thereto are part of the common elements and shall the
be properly maintained and operated in conformity with law and the provisions of the permit for
construction. operation, repair, and maintenance of the system and facilities. The s Wei i^rs
shall identify the entire wastewater treatment, collection and
disposal system as a common element, which will receive the highest priority for expenditures by the
Association except for Federal, State, and local taxes and insurance.
FORM: IOA 06-07 Page 1 of 2

The ASSOCIATION shall provide in the �
that the Disposal System will be maintained out of the common expenses. In order- to assure that there
shall be funds readily available to repair, maintain, or construct the Disposal System beyond the routine
operation and maintenance expenses, the'.
shall provide that a fiord be created out of the common expenses. Such fund shalt be separate from the
routine maintenance fund allocated for the facility and shall be part of the yearly budget.
4. In the event the common expense allocation and separate fiund(s) are not adequate for the construction,
repair, and maintenance of the Disposal System,
?i:;11v�3i s`_`fi�< shall provide for special assessments to cover such necessary costs. There shall be no
limit on the amount of such assessments, and the k .i1J. �)! f?ie"',-Me; ;:t��ie IIt

existing and future wastewater of the Development to be accepted and discharged into said governmental
system, and shall convey or transfer as much of the Disposal System and such necessary easements as the
governmental unit may require as condition of accepting the Development's wastewater.
6. Recognizing that it would be contrary to the public interest and to the public health, safety and welfare for
the ASSOCIATION to enter into voluntary dissolution without having made adequate provision for the
continued proper maintenance, repair and operation of its Disposal System, the ASSOCIATION shall

7. The ASSOCIATION shall not transfer, convey, assign or otherwise relinquish or release its responsibility
for the operation and maintenance of its Disposal System until a permit has been reissued to the
ASSOCIATION's successor.
The agreements set forth in numbered paragraphs 1, 2, 3, 4, 5, 6, and 7 above shall be conditions of any
permit issued by the COMMISSION to the ASSOCIATION for the construction, maintenance, repair and
