(a) 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.
(b) 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.
(c) 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 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.

will be subject to the authority of source control inspectors to assure
compliance with discharge limitations and BMPs. The owner shall repair
or replace any broken, deteriorating, or undersized equipment at the
owner's expense. No modifications or removal of equipment shall be
performed without written consent and approval from the city.

necessary in the opinion of the director, the owner shall provide,
at his or her expense, preliminary treatment of a water or waste that
may be necessary to:
(1) Reduce the BOD of the water or waste to 300 mg/l;
(2) Reduce the suspended solids of the water or waste to 300 mg/l;
(3) Reduce an objectionable characteristic or a constituent of the water

Editor's note — Ord. No. 2021-16, adopted
10-27-21, repealed § 22-36, pertaining maintenance of preliminary
treatment facilities, which derived from Prior Code § 8316,

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.

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 dental amalgam separators required to be installed
by establishments of health practitioners primarily engaged in the
independent practice of general or specialized dentistry, or dental
surgery. A violation of such rules, regulations, or requirements shall
be deemed a violation of this chapter.
(Ord. No. 2021-16, § 3, 10-27-21)
Users must comply with the categorical pretreatment standards found at 40 C.F.R. Chapter
I, Subchapter N, Parts 405–471.
(a) 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).
(b) 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).
(c) When
wastewater subject to a categorical pretreatment standard is mixed
with wastewater not regulated by the same categorical pretreatment
standard, the director shall impose an alternate limit in accordance
with 40 C.F.R section 403.6(e).
