OAR 340-052-0030: Meaning of Approval

Approval of plans means that the Department has reviewed favorably the estimates, assumptions and the design presented in the specific project plans for reasonableness and practicality consistent with process technology and for the likelihood that the project may, if operated and maintained as proposed, achieve or maintain the desired result. Plan approval by the Department does not warrant that the facility will meet expectations. Plan approval does not negate the responsibility of the owner to provide additional facilities should the completed work fail to achieve design effluent parameters, unforeseen water quality violations occur, other operational problems develop, or treatment standards or requirements change. Review of non-process related aspects of the plans will be cursory, if reviewed at all, and not meant to assure adequacy of nonprocess related aspects of the design.
