The department is authorized to enter into contracts with any municipal or public corporation or political subdivision within the state for the purpose of assisting such agencies to finance the design and construction of water pollution control projects, whether procured through chapter 39.10 or 70A.140 RCW, or otherwise, that are necessary to prevent the discharge of untreated or inadequately treated sewage or other waste into the waters of the state, including but not limited to, systems for the control of storm or surface waters which will provide for the removal of waste or polluting materials in a manner conforming to the comprehensive plan of water pollution control and abatement proposed by the agencies and approved by the department. Any such contract may provide for:

The payment by the department to a municipal or public corporation or political subdivision on a monthly, quarterly, or annual basis of varying amounts of moneys as advances which shall be repayable by said municipal or public corporation, or political subdivision under conditions determined by the department.

Contracts made by the department shall be subject to the following limitations:

(1) No contract shall be made unless the department shall find that the project cannot be financed at reasonable cost or within statutory limitations by the borrower without the making of such contract.

(2) No contract shall be made with any public or municipal corporation or political subdivision to assist in the financing of any project located within a sewage drainage basin for which the department shall have previously adopted a comprehensive water pollution control and abatement plan unless the project is found by the department to conform with the basin comprehensive plan.

(3) The department shall determine the interest rate, not to exceed ten percent per annum, which such advances shall bear.

(4) The department shall provide such reasonable terms and conditions of repayment of advances as it may determine.

(5) The total outstanding amount which the department may at any time be obligated to pay under all outstanding contracts made pursuant to this section shall not exceed the moneys available for such payment.

(6) Municipal or public corporations or political subdivisions shall meet such qualifications and follow such procedures in applying for contract assistance as shall be established by the department.

In making such contracts the department shall give priority to projects which will provide relief from actual or potential public health hazards or water pollution conditions and which provide substantial capacity beyond present requirements to meet anticipated future demand.
