Oregon Administrative Rules › Chapter 340 - DEPARTMENT OF ENVIRONMENTAL QUALITY › Division 52 - REVIEW OF PLANS AND SPECIFICATIONS › Section 340-052-0040 - Responsibility of Treatment Works Owners, Designs Engineers and Developers After Approval of Plans for (Domestic) Sewage Projects

Current through Register Vol. 63, No. 7, July 1, 2024
(1) Construction of all projects must be in
			 accordance with the project plans and specifications approved by the
			 Department. No substantial change in or deviation from such plans and
			 specifications shall be made without the prior written approval of the
			 Department, which shall make the final determination whether or not a change or
			 deviation is in fact substantial.
(2) The owner of the sewerage system
			 (generally a municipality) as recipient of any construction work on its system
			 has a vested responsibility to review and approve project plans prior to the
			 start of construction. Department approval of plans under these rules does not
			 preclude the right and responsibility of review and approval by the owner. The
			 owner may adopt more stringent construction standards and impose special
			 conditions for sewer use, service connection, and related activities.
			 Department approval of plans in such cases is contingent upon similar approval
			 by the owner. Submittal of plans to the Department through the owner and prior
			 approval of plans by the owner is encouraged.
(3) Inspection and certification of proper
			 construction shall be governed by the following provisions:
(a) The construction of all sewerage projects
			 shall be under the supervision of and shall be thoroughly inspected by the
			 design engineer or his authorized representative, unless relieved under
			 subsection (b) of this section. At the completion of the project, he shall
			 certify in writing to the owner and the Department that such construction was
			 inspected by him and found to be in accordance with the plans and
			 specifications, including any changes therein approved by the Department.
			 Nothing in the foregoing exempts an owner from monitoring the project for
			 conformance to require-ments and performing supplementary inspections or
			 prevents an owner's qualified staff from assuming responsibility for inspection
			 and certification;
(b) If the
			 design engineer is to have no further involvement or have limited involvement
			 with the project after obtaining Department approval of plans, he must so
			 notify the Department, the owner, and the developer upon submittal of plans or
			 immediately upon being disassociated or limited in control over materials or
			 workmanship within the project. (Nothing precludes either the owner or the
			 developer from giving such notice if this is more appropriate). Thereupon, if
			 the project is to continue on to construction, the owner shall assume necessary
			 responsibility for satisfactory construction of the project in accordance with
			 the approved plans. He shall employ or apply such construction
			 engineering/inspection services as appropriate for the project. The owner shall
			 thereupon certify in accordance with subsection (a) of this section. No project
			 shall proceed to construction without adequate and capable construction
			 engineering/inspection services. (This assumption of construction
			 engineering/inspection services responsibility by the owner does not
			 necessarily relieve the design engineer of design responsibility);
(c) Sewerage system integrity and
			 watertightness is the system owner's ultimate responsibility. He shall monitor
			 all private sewer construction and control all common sewer construction in the
			 sewerage system to the extent necessary to this end.
