Nondomestic users shall provide wastewater pretreatment as necessary to comply with this chapter and shall achieve compliance with the pretreatment standards set out in this chapter within the time limitations specified by EPA, the state, or the control authority, whichever is more stringent. Any pretreatment facilities necessary for compliance shall be provided, operated, and maintained at the nondomestic user's expense, and satisfy state requirements for review and approval of plans for wastewater facilities as described in BLMC § 13.14.320. Such plans (engineering report, plans and specifications, and operation and maintenance manuals) shall be submitted (as required by Chapter 173-240 WAC) to the director for review and approval prior to construction. The review of such plans and operating procedures shall in no way relieve the nondomestic user from the responsibility of modifying such pretreatment facilities as necessary to produce a discharge acceptable to the director under the provisions of this chapter.
(Ord. 1719 § 1 (Exh. A), 2024)
A. 
The director or the city may immediately and effectively halt or prevent any discharge of pollutants to the POTW which reasonably appear to present an imminent endangerment to the health or welfare of POTW staff or general public. In such cases, the director or the city will provide the user advance notice if possible but shall not delay a response to imminent endangerment.
B. 
The director or the city may halt or prevent any discharge to the POTW which presents or may present an endangerment to the environment, or which threatens to interfere with the operation of the POTW. In such cases, the director or the city shall attempt to provide not only notice to the affected nondomestic user(s), but the opportunity to respond.
C. 
Any nondomestic user causing the director or the city to exercise the emergency authorities provided for under subsections (A) and (B) of this section shall be responsible for reimbursement of all related costs to the control authority or contributing jurisdiction, as appropriate.
D. 
The director or the city may require nondomestic users to reduce or curtail certain discharges to the POTW, designate that certain wastewater be discharged only into specific sewers, relocate and/or consolidate points of discharge, separate sewage wastestreams from industrial waste-streams, and take all other measures to protect the POTW and determine the nondomestic user's compliance with the requirements of this chapter.
E. 
The director or the city, based on the determination that such facilities or devices are necessary for implementation of pretreatment requirements, may require any nondomestic user to install and maintain, on their property and at their expense, pretreatment facilities, devices and equipment that may include, but not be limited to, any of the following:
1.

All fixtures, equipment, and drain lines located in a facility's food preparation and cleanup areas shall be connected to a GI, unless specifically approved by the director. The following types of equipment or fixtures have been identified as potential sources of fats, oils and grease and shall be connected to a GI: pre-rinse and/or pre-wash sinks or sinks in dishwashing areas; two or three compartment sinks; wok stoves; self-cleaning stove ventilation/exhaust hood; kitchen floor drains; floor drains; floor sinks; mop sinks; food prep sinks; and hand sinks. Dishwashers may only be directed to GIs per director or manufacturer instructions. Dishwashers or other fixtures discharging emulsifying agents, such as detergents, shall be located such that their potential to adversely impact the GI operation is minimized. All drain lines shall have permanently fixed screens with maximum one-quarter-inch openings to prevent the pass-through of larger solids. Commercial food grinders and garbage disposals are not allowed. No sanitary waste shall be conveyed to the GI. A monitoring manhole shall be included on all GI installations.
H. 
GI Installation. GIs shall be installed such that they are easily accessible for inspection, cleaning, and the removal of fats, oils, grease and solid material. An accessible GI shall meet the following minimum criteria: the edge of the GI shall be flush with any edge of an overhead obstruction; and the overhead clearance shall be at least equal to the overall depth of the GI. GI access covers should be located such that the influent and effluent sanitary tee and compartment walls are accessible at all times for proper cleaning and inspection.
I. 
Cleaning and Maintenance. The director shall be authorized to establish routine maintenance schedules of pretreatment facilities or devices for the purpose of inspection, maintaining effective treatment and pollutant removal, and reducing pollutant loadings to the POTW. The control authority or contributing jurisdiction shall be allowed access to pretreatment facilities or devices for the purpose of inspection and/or to verify compliance with this chapter. Waste removed from a pretreatment facility or device shall not be disposed of in the POTW. A record of cleaning, maintenance or disposal activities shall be submitted to the director. The use of hot water, enzymes, bacteria, chemicals, or other agents for the purpose of causing the contents of a pretreatment facility or device to be discharged into the POTW is prohibited.
(Ord. 1719 § 1 (Exh. A), 2024)
The director may require any nondomestic user to develop and implement an accidental discharge/slug discharge control plan and take other actions the director believes are necessary to control discharges which may be caused by spills or periodic nonroutine activities. Accidental discharge/slug discharge control plans shall include at least the following:
A. 
A description of all discharge practices, including any nonroutine batch discharges such as from cleaning, replenishment, or disposal;
B. 
A description of all stored chemicals, disclosing all ingredients in formulations which could violate a discharge prohibition if discharged to the POTW;
C.
