Spokane Municipal Code

Title 13 Public Utilities and Services

Chapter 13.03A Pretreatment

Article II. General Requirements

Section 13.03A.0211 Accidental Spill Prevention Plans/Slug Control Plans [2.11]

1. The Plant Manager may require any user to develop and implement an accidental spill prevention plan (ASPP) or slug control plan. Where deemed necessary by the City, facilities to prevent accidental discharge or slug discharges of pollutants shall be provided and maintained at the user’s cost and expense. An accidental spill prevention plan or slug control plan showing facilities and operating procedures to provide this protection shall be submitted to the City for review and approval before implementation. The City shall determine which user is required to develop a plan and require said plan to be submitted within 90 days after notification by the City. Each user shall implement its ASPP as submitted or as modified after such plan has been reviewed and approved by the City. Review and approval of such plans and operating procedures by the City shall not relieve the user from the responsibility to modify its facility as necessary to meet the requirements of this chapter.

2. An ASPP and/or slug control plan shall address, at a minimum, the following:

1. 1. Description of discharge practices, including non-routine batch discharges.

1. 2. Description of stored chemicals.

1. 3. Procedures for immediate notification to the Plant Manager of any accidental spill or slug discharge which could violate SMC 13.03A.0201 through SMC 13.03A.0204.

1. 4. Procedures to prevent adverse impact from an accidental spill and/or slug discharge. Such procedures include, but are not limited to, inspection and maintenance of storage areas, handling and transfer of materials, loading and unloading operations, control of plant site runoff, worker training, building of containment structures or equipment, measures for containing toxic organic pollutants, including solvents, and/or measures and equipment for emergency response. (Cross reference: 40 CFR §403.8(f)(2)(vi). See also EPA Region 10 Accidental Spill Prevention and Guidance Manual for POTWs and non-domestic users)

1. 5. ASPPs and/or slug control plans must be filed with the Plant Manager, upon such forms and 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 may include a fee as provided in SMC 13.03A.1401.

3. The requirement for an ASPP or slug control plan may be incorporated into a discharge permit. Updates and renewals must be filed with any request for permit transfer, modification, or renewal, change at the user facility, and whenever the user knows or reasonably should know of information affecting the plan or facts upon which the plan was based. In addition, the Plant Manager evaluates the sufficiency of any ASPP and/or slug control plan or other action to control spills or slug discharges and may order changes or updates as deemed necessary, including analysis or reports by a qualified engineer or other professional certification. If determined to be insufficient, the Plant Manager may develop such a plan at the user’s expense. (Cross reference: SMC 13.03A.0407)
