OPERATIONAL AGREEMENT
This AGREEMENT made pursuant to G.S. 143-215.1 (dl) and entered into this _ 2 ^4 M1 L day of
1VW-Zetg _ oD , by and between the North Carolina Environmental Management
Commission, an agency of the State of North Carolina, hereinafter known as the COMMISSION; and
Windward Dunes Owners Association , a 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 Windward Dunes
(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. 143-
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:
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
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.
FORM: HOA 06-07 Page 1 of 2

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 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 fund allocated for the
facility and shall be part of the yearly budget.
4. In the event the common expense allocation and separate fund(s) 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 be provided such that special assessments can be made
as necessary at any time_
5. 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 ASSOCIATION 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.
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
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.
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.
8. 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
operation of the Disposal System.
9. 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 WITNESS 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:
