RPM
Avendale
(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 or 47F of the North Carolina General Statutes.
The DEVELOPER has caused to be formed or will cause to be formed at the time of filing of the
Declaration, the Enter Proposed Unit Owners' Association (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 fiords 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

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
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.
S. 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.

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

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
