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
specifcations hereafter issued and approved by the COMMISSION; and shall thereafter properly operate
and maintain ssch 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 Environmental Management has inspected and approved of the facilities. In order to change the
name of the permit holder, the DEVELOPER must request that the permit be reissued to the Association?..
The request must include a copy of the Association Bylaws and Declaration.
The DEVELOPER 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 DEVELOPER's
successor.
1,400 copies of this document were printed at a cost of S40.46, or S0.029 per copy.

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 willbe
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 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.
7. - If a wastewater collection" system and wastewater treatment and/or disposal facility provided by any city,
town, village, county, water and sewer authorities, or other unit of government shall hereinafter become
available to serve the Development, the DEVELOPER shall take such action as is necessary to cause the
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
permit issued by the COMMISSION to the DEVELOPER for the construction, maintenance, repair and
operation of the Disposal System.
10. A copy of this agreement shall be filed at the Register of Deeds in the County(ies) where the Declaration is
filed- and in the offices of the Secretary of State of North Carolina with the Articles of Incorporation of the
Association.
IN WTINESS WHEREOF, this agreement was executed in duplicate originals by the duly authorized
representative of the parties hereto on the day and year written as indicated by each of the parties named below:
