Review of Plans and Specifications

Engineering plans and specifications for proposed construction, installation, or modification of wastewater disposal systems, treatment works, sewerage systems or common sewers must be submitted to DEQ for review and approval prior to construction, except where exempted. This is required by Oregon Revised Statute 468B.055. OAR 340-052-0015 details plan submittal requirements. OAR 340-052 Appendix A and Appendix B contain requirements for gravity sewerage systems and sewerage pumping stations, respectively.

See also Regulatory Requirements for Common Sewer System Owners

DEQ may exempt from submittal of plans minor modifications to existing facilities where the change will not significantly affect the operation of the treatment or disposal system. A complete description of proposed minor modifications must be submitted for DEQ’s consideration. Exemptions will be approved in writing on a case-by-case basis. Please note that DEQ approval is not required for in kind replacement of equipment or accessories such as thermostats, switches, elements, motors, or fittings. In-kind replacement does not involve the replacement of main portions of the electrical, structural, plumbing, or mechanical system. Please contact DEQ if you have any questions about your proposed project.

Submitting wastewater reports and plans for approval

Please send the following to the DEQ engineer who is assigned to the area of your project (see the list of engineers below):

Plans, specifications and reports. Note: electronic versions are acceptable.
Land Use Compatibility Statement, or LUCS, signed by the local land use authority. Note: A LUCS which is part of a submittal for approval of plans and specifications should check the box for "Wastewater/Sewer Construction Plan/Specifications" in subsection 1D, and check "Other" in subsection 1E. Electronic versions are acceptable.
Payment of DEQ Technical Activities Fee in OAR 340-045 Table 70 F. DEQ can invoice the system owner if that is the owner’s preference.

Plan review guidelines

DEQ wastewater engineers use the following guidelines to evaluate plans. DEQ advises that the appropriate DEQ wastewater engineer be consulted prior to plan submittal if a deviation is desired to avoid additional redesign expenses.

Note: This updated list (as of 12/8/2021) contains a revised guideline (#3), which includes discussion of grinder pump systems.
