Or. Admin. Code § 340-052-0015 - Submittal of Plans

Except where exempted under OAR 340-052-0040, all plans and specifications along with other data submitted for a proposed construction, installation, or modification project involving disposal systems, treatment works, sewerage systems or common sewers shall first be submitted to the Department for review. No construction, installation or modification shall be commenced until the plans and specifications submitted to the Department are approved. Plans and other information to be submitted shall constitute a complete descriptive proposal, including, but not limited to, the following:

(1) For all projects:

(a) The name of person or firm submitting the project;

(b) Project location by county and nearest city;

(c) The name of the project and/or project developer; or a written description of the project for industrial/commercial facilities;

(d) The name of the person who will own, operate and maintain the completed project;

(e) The name of the person who will provide construction engineering/inspection services and certify construction inspection under OAR 340-052-0040 for (domestic) sewage projects if other than the design engineer;

(f) At least two sets of plans and specifications. (Three sets of final bid documents shall be submitted for a project to receive EPA grant assistance.) Plans and specifications shall be complete to the extent that a contractor qualified in the type of work could be reasonably expected to construct it with minimal direction by the engineer. In accordance with ORS Chapter 672 plans and specifications shall be prepared under the supervision of and signed by a registered professional engineer unless exempted under ORS 672.060 (i.e., company engineer designing certain industrial facilities);

(g) An affirmative written statement from the appropriate jurisdiction that the proposed project for new or expanded facilities is compatible with the Land Conservation and Development Commission acknowledged local comprehensive plan, ordinances and zoning requirements or Land Conservation and Development Commission statewide planning goals under ORS Chapter 197:

(A) Where the jurisdiction submitting a proposed project to the Department for approval under these rules is the sole jurisdiction that is responsible for the affirmative statement of compatibility, the Department will not require the written statement. In such case, submittal of construction plans to the Department shall be deemed evidence that the jurisdiction is in compliance with its own requirements or Land Conservation and Development Commission goals;

(B) Where more than one local jurisdiction has planning authority over the specific project, statements of compatibility from each of these jurisdictions (e.g., city, county, and regional planning jurisdictions) shall be submitted to the Department;

(C) Where special districts are proposing projects, the appropriate county and/or city would prepare such statements;

(D) Statements of compatibility for master sewerage plans or portions thereof may be submitted in advance covering area wide sewering in lieu of statements on a project-by-project basis.

(2) In addition to the submittal requirements of section (1) of this rule, the following shall be submitted with plans for treatment works, disposal systems and pretreatment systems to the extent that these pertain to the particular treatment or disposal system which is being installed or modified:

(a) The design flows, design population, and design effluent parameters;

(b) A hydraulic profile;

(c) Unit detention times, volumes, sizes, hydraulic loadings, organic loadings, solids loadings, chemical loadings, expected removal efficiencies, as appropriate;

(d) A schematic of the complete treatment works;

(e) An estimate of the personnel requirements to operate and maintain the completed treatment works;

(f) A written statement that an operation and maintenance manual for the added facilities acceptable to the owner and the Department will be prepared, the name of the person to prepare such manual and that the manual will be completed prior to start up of facilities;

(g) A detailed program for the satisfactory disposal and/or beneficial use of all collected grit, screenings, and sludges.

(3) In addition to the submittal requirements of section (1) of this rule, and excepting sewerage systems wholly designed for industrial wastes the following shall be submitted with plans for sewerage systems:

(a) Drawings for sewers shall provide complete plan and profile views which adequately describe the service conditions for the completed work;

(b) For sewers larger than eight inches in diameter, appropriate design flow shall be indicated in the plans or separately submitted. Population to be served, gallons of sewage per person per day, infiltration allowance and unavoidable inflow allowance shall be submitted to support the design flow when requested by the Department;

(c) Plans for a common sewer or a sewerage system submitted by a person other than the owner or joint owner of the treatment works must be accompanied by a statement from the treatment works owner that he agrees to provide sewer service and has sewerage system and treatment capacity to do so;

(d) For a project with a lift station, a written statement that a lift station operation and maintenance manual acceptable to the owner and the Department will be prepared, the name of the person to prepare such manual and that the manual will be completed prior to start up of each lift station.

(4) Any new owner or operator of a common domestic sewerage system, sewage treatment works or sewage disposal facility which serves or will serve a residential area shall have a realistic, long-term, management and financial plan for continuous maintenance, operation and replacement of such common facilities. Final construction plan approval cannot be given until the management and financial plan has been approved.
