Section 13.03A.0314 Regulation of Wastewater Received from Other Jurisdictions

1. Any user outside the City sanitary sewer service area who proposes to discharge wastewater into the City’s POTW shall enter into an inter-local agreement with the contributing governmental entity (city, town, county, sewer district, or other municipal corporation recognized by state law). The agreement shall affix responsibilities in an enforceable manner to ensure that the pretreatment program is fully and equitably administered in all contributing jurisdictions. Any agreement or modification to such an agreement shall be reviewed by the City’s legal counsel and shall be submitted, together with the opinion that it is legally sufficient, to the approval authority (State department of ecology) and processed as a minor program modification.

2. Prior to entering into an agreement required above, the Plant Manager shall request the following information from the contributing governmental entity:

1. 1. A description of the quality and volume of wastewater discharged to the POTW by the contributing governmental entity;

1. 2. An inventory of all users located within the contributing governmental entity that are discharging to the POTW; and

1. 3. Such other information as the Plant Manager may deem necessary.

3. An inter-local agreement, as provided above shall contain the following provisions:

1. 1. Requirements for contributing governmental entities to adopt a sewer use ordinance or pretreatment ordinance which establishes pretreatment standards and requirements as stringent as in this chapter. The ordinance provisions and limits must be revised to conform within a reasonable time frame (within nine months) to any future revisions of this chapter;

1. 2. Requirements for the contributing governmental entity to submit a revised user inventory on at least an annual basis, and reinforce requirements to obtain a permit prior to discharge;

1. 3. A clear division of responsibilities for implementing each pretreatment related activity under this chapter or in the City’s NPDES permit(s). The tasks include reinforcing prohibitions, locating users, issuing wastewater discharge permits, conducting inspections, sampling, evaluating compliance, initiating enforcement, and reporting compliance. Any activities which will be conducted jointly by the contributing governmental entity and the Plant Manager must also be identified;

1. 4. Requirements for the contributing governmental entity to provide the Plant Manager access to all information that the contributing governmental entity obtains as part of its pretreatment activities;

1. 5. The nature, quality (e.g. conventional and toxic pollutant concentrations), and volume (peak and average flow rates) the contributing municipality is allowed to discharge to the City, how and where compliance will be measured, how fees for service and surcharges will be established, and how additional loading capacity, if needed, will be negotiated;

1. 6. Provisions ensuring that the Plant Manager may enter and inspect users located within the contributing governmental entity’s jurisdictional boundaries to confirm that the pretreatment program is being properly administered and users are properly categorized; and

1. 7. Provisions for addressing any breach of the terms of the inter-local agreement.
