December 1998 G1 General Engi ineering Requirements This chapter describes ecology' s engineering approval requirements, permitting requirements and the agencies involved, and the process and steps involved from planning through completion of construction for a domestic wastewater collection and treatment facility. General and site specific planning design, construction, and operation and maintenance requirements are all addressed in Chapter Gl. Exceptions and variations to the normal review and pproval process are also discussed in this chapter Except as delegated to local units of government(see G1-5.2), Ecology will review general sewer plans, engineering reports, plans and specifications, and operation and maintenance manuals for domestic wastewater facilities. The purpose of Ecology's review is to ascertain that the proposed facilities will be designed, constructed, operated, and maintained to meet the effluent limitations and other wastewater discharge permit terms and conditions necessary to protect public health and the environment. The policies for providing this protection are established in Chapters 90.48, 90.52, and 90.54 RCW pertaining to the prevention and control of pollution to state waters. In cases where projects are funded through state and federal grant and/or loan programs Ecology's review will also consider the efficient and effective use of public resources In addition, Ecology will review documents to ascertain that plans are consistent with the design standards and intentions established in this manual and with commonly accepted engineering practices G1-1 Agreements with other B.
