which it is erecting and will erect dwelling units and other improvements, said development to be known
as Co) d 11/zJ1, A-) R/ (hereinafter the Development).
2. The DEVELOPER desires, to construct a wastewater collection system with pumps, wastewater treatment
works, and/or disposal facilities (hereinafter Disposal System) to provide sanitary sewage disposal to serve
the Development on said lands.
3. The DEVELOPER has applied to the COMMISSION for the issuance of a permit pursuant to G.S. 143-
215.1 to construct, maintain, and operate the Disposal System.
4. The DEVELOPER has created or shall create unit ownership in said 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 DEVELOPER has caused to be formed or will cause to be formed at the time of filing of the
Declaration, the (Unit Owners' Association) N 1 A (hereinafter
Association), a non-profit corporation organized and existing under and by the virtue of the laws of the
State of North Carolina, for the purpose, among others, of handling the property, affairs and business of
the Development; of operating, maintaining, re -constructing and repairing the common elements of the
lands and improvements subject to unit ownership, including the Disposal System; and of collecting dues
and assessments to provide funds for such operation, maintenance, re -construction and repair.
6. 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 DEVELOPER do hereby mutually agree as follows:
1. The DEVELOPER shall construct 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 DEVELOPER shall not transfer ownership and/or control of the Disposal System to the Association
until construction has been completed in accordance with the permit and approved plans, and the staff of
the Division of Water Quality has inspected and approved of the facilities. In order to change the name of

request must include a copy of the Association Bylaws and Declaration.
FORM: DEV 09/05 Page 1 of 2
3. The DEVELOPER shall not 1 fer, convey, assign or otherwise relin` h or release its responsibility
for the operation and maintenance of its Disposal System until a permit has been reissued to the
DEVELOPER's successor.
4. The DEVELOPER shall provide in the Declaration and Association Bylaws that the Disposal System and
appurtenances thereto are part of the common elements and shall thereafter 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 Declaration and Bylaws 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.
5. The DEVELOPER 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 shall 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 funds allocated for the facility and
shall be part of the yearly budget.
6. In the event the common expense allocation and separate fund are not adequate for the construction,
repair, and maintenance of the Disposal System, the Declaration and Association Bylaws shall provide for
special assessments to cover such necessary costs. There shall be no limit on the amount of such
assessments, and the Declaration and Bylaws shall provide that such special assessments can be made as
necessary at any time.

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.
8. 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 DEVELOPER shall
provide in the Association Bylaws that the Association shall not enter into voluntary dissolution without
first having transferred its said system and facilities to some person, corporation or other entity acceptable
to and approved by the COMMISSION by the issuance of a permit.
9. The agreements set forth in numbered paragraphs 1, 2, 3, 4, 5, 6, 7, and 8 above shall be conditions of any
