§ 22-38 FOG removal equipment required; type, construction, location.

FOG removal equipment shall be provided in all cases required by published building codes, unless in the sole and absolute opinion of the director or a designee, in writing, FOG removal equipment is not necessary for the proper handling of liquid wastes containing grease; potentially hazardous wastes in excessive amounts; or any flammable wastes, sand, or other harmful ingredients. Living quarters or dwelling units with a commercial kitchen must have FOG removal equipment.

Where installed, all FOG removal equipment shall be of a type and capacity subject to the director's approval, and shall be located as to be readily and easily accessible for cleaning and inspection. They shall be maintained continuously in satisfactory and effective operation by the owner at his or her expense. Broken, deteriorating or undersized equipment will require repair or replacement by the owner at his or her expense. No modifications or removal of equipment shall be performed without written consent and approval from the city.

The director shall have the authority to promulgate rules, regulations, and requirements consistent with the provisions of this chapter and state and federal requirements, to regulate the type, capacity, placement, and maintenance of FOG removal equipment. A violation of any such rule, regulation, or requirement shall be deemed a violation of this chapter.

(d)

When needed for maintenance, the owner must install cleanouts for maintenance and inspection purposes at the owner's cost. Each separate chamber of the grease interceptor must have a manhole lid to access, inspect, and maintain all of the internal plumbing.

(e)

All FOG removal equipment must have an approved sample tee or sample box installed on the effluent discharge line. The sample tee or box shall be installed on any equipment that does not currently have an approved sample point, subject to the director's approval, to ensure compliance with local discharge limits set forth by this chapter. The sample point shall be installed at the business owner's expense, and shall be approved by the pretreatment department and building department prior to installation.

All measurements, tests, and analyses of the characteristics of waters and wastes to which reference is made in this chapter shall be determined in accordance with 40 C.F.R. Part 136 or the latest edition of Standard Methods for the Examination of Water and Wastewater and shall be determined at the control manhole or upon suitable samples taken at the control manhole. In the event that no special manhole has been required, the control manhole will be a sample port on the downstream side of the grease interceptor, grease trap, clarifier, dental amalgam separator, or sand oil separator. The sample port will be installed by the owner of the facility at the owner's expense. The location of the sample port is subject to the director's approval.

§ 22-44 National categorical pretreatment standards.

Users must comply with the categorical pretreatment standards found at 40 C.F.R. Chapter I, Subchapter N, Parts 405–471.

Where a categorical pretreatment standard is expressed only in terms of either the mass or the concentration of a pollutant in wastewater, the director may impose equivalent concentration or mass limits in accordance with subsection (b) below. See 40 C.F.R. section 403.6(c).

When the limits in a categorical pretreatment standard are expressed only in terms of mass of pollutant per unit of production, the director may convert the limits to equivalent limitations expressed either as mass of pollutant discharged per day or effluent concentration for purposes of calculating effluent limitations applicable to individual industrial users. See 40 C.F.R. section 403.6(c)(2).
