(a)Upon receipt of plans, the Authority shall review the plans and either approve them or advise that correction or clarification is required. When the correction or clarification is received, and the item(s) in question are resolved, the Authority shall then approve the plans;
(b)Upon completion of a project, a professional engineer registered in Oregon shall submit to the Authority a statement certifying that the project has been constructed in compliance with the approved plans and specifications. When substantial deviations from the approved plans are made, as-built plans showing compliance with these rules shall be submitted to the Authority;
(c)Plans shall not be required for emergency repair of existing facilities. In lieu of plans, written notice shall be submitted to the Authority immediately after the emergency work is completed stating the nature of the emergency, the extent of the work and whether or not any threats to the water quality exists or existed during the emergency.
(3)Plan review fees: Plans submitted to the Authority shall be accompanied by a fee as indicated in Table 41. Those plans not accompanied by a fee will not be reviewed.
(4)Plan review exemptions:
(a)Water suppliers may be exempted from submitting plans for water main extensions or replacements, providing they:
(A)Have provided the Authority with a current master plan; and
(B)Certify that the work will be carried out in conformance with the construction standards of these rules; and
(C)Submit to the Authority an annual summary of the projects completed, signed by a professional engineer currently registered in Oregon and certifying that all projects were completed according to OAR 333-061-0050 (Construction Standards); and
(D)Certify that they have staff qualified to effectively supervise the projects.
(b)Those water suppliers certifying that they have staff qualified to effectively plan, design and supervise their projects, may request the Authority for further exemption from this rule. Such requests must be accompanied by a listing of staff proposed to accomplish the work and a current master plan. To maintain the exemption, the foregoing must be annually updated;
(c)At the discretion of the Authority, Community, NTNC, TNC and State Regulated water systems may be exempted from submitting engineered plans. They shall, however, submit adequate plans indicating that the project meets the minimum construction standards of these rules.
(5)A master plan is required for every community water system with 300 or more service connections or serving more than 1,000 people and shall be maintained by the water supplier for the duration of the period to which the plan applies. Master plans shall be prepared by a professional engineer registered in Oregon and submitted to the Authority for review and approval.
(a)Each master plan shall evaluate the needs of the water system for at least a twenty year period and shall include, but not be limited to, the following elements:
(A)A summary of the overall plan that includes the water quality and service goals, identified present and future water system deficiencies, the engineer’s recommended alternative for achieving the goals and correcting the deficiencies, and the recommended implementation schedule and financing program for constructing improvements.
(B)A description of the existing water system which includes the service area, source(s) of supply, status of water rights, current status of drinking water quality and compliance with regulatory standards, maps or schematics of the water system showing size and location of facilities, estimates of water use, and operation and maintenance requirements.
(C)A description of water quality and level of service goals for the water system, considering, as appropriate, existing and future regulatory requirements, nonregulatory water quality needs of water users, flow and pressure requirements, and capacity needs related to water use and fire flow needs.
