Title 13 Public Utilities and Services

Chapter 13.03A Pretreatment

Article II. General Requirements

Section 13.03A.0203 State Requirements

1. State requirements and limitations on discharges to the POTW shall be met by all users subject to such items whenever they are more stringent than federal or local pretreatment requirements and limitations. Washington State Pretreatment Standards and Requirements, located at chapter 173-216 WAC, were developed under authority of the State Water Pollution Control Act, chapter 90.48 RCW and are hereby incorporated. All wastewaters discharged from a commercial or industrial operation as determined by the Plant Manager into the POTW must satisfy the provisions of chapter 173-216 WAC.

2. Any person who constructs, modifies or proposes to construct or modify wastewater treatment facilities must first comply with the regulations for submission of plans and reports for construction of wastewater facilities, chapter 173-240 WAC. The City has been delegated the authority to review and approve such plans and reports under RCW 90.48.110. Sources of non-domestic discharges (industrial wastewater) shall request approval for such plans and reports through the City of Spokane. One copy of each plan and report shall be provided to the Plant Manager before commencing any such construction or modification. Said plans and reports must be filed with the Plant Manager, together with such information as required by the Plant Manager, signed by an authorized representative and certified as provided in SMC 13.03A.0305(B), and include the fee as provided in SMC 13.03A.1401. (Cross reference: WAC 173-216-050(1))

3. All users shall apply all known, available, and reasonable treatment methods (AKART) to prevent and control wastewater releases into the waters of the state. (Cross reference: WAC 173-216-050(3))

4. Discharge restrictions of chapter 173-303 WAC (Dangerous Waste) shall apply to all users.

5. All required monitoring data shall be analyzed by a laboratory or person accepted by the Plant Manager as qualified to perform such services, in the Plant Manager’s sole discretion. The lab or person shall be registered or accredited under the provisions of chapter 173-50 WAC. The Plant Manager may determine this is not required for flow, temperature, settleable solids, conductivity, pH, turbidity, and internal process control parameters. However, if the laboratory analyzing samples for conductivity, pH, and turbidity must otherwise be accredited, it shall be accredited for these parameters as well.

6. The City shall public notice for users applying for a new permit or a permit renewal or modification which allows a new or increased pollutant loading, at the user’s expense. The notices shall fulfill the requirements of WAC 173-216-090. These requirements include publishing:

1. 1. The name and address of the applicant and facility/activity to be permitted;

1. 2. A brief description of the activities or operations which result in discharge;

1. 3. Whether any tentative determination has been reached with respect to allowing the discharge;

1. 4. The address and phone number of the office of the Plant Manager where persons can obtain additional information;

1. 5. The dates of the comment period (which shall be at least thirty days); and

1. 6. How and where to submit comments or have any other input into the permitting process, including requesting a public hearing.

7. The Plant Manager may also mail this notice to persons who have expressed an interest in being notified, to state agencies and local governments with a regulatory interest, and to post the notice on the premises. If the Plant Manager determines there is sufficient public interest, the City shall hold a public meeting following the rules of WAC 173-216-100. The Plant Manager may assume responsibility for public notice requirements for any persons, and may waive this requirement for any user not classified as CIU or SIU by the Plant Manager.
