AN ORDINANCE of the City of Port Angeles, Washington
amending Chapter 13.06 Industrial Wastewater
provisions of the Port Angeles Municipal Code.
THE CITY COUNCIL OF THE CITY OF PORT ANGELES DO HEREBY
ORDAIN AS FOLLOWS:
Section 1. Ordinance 3397 as amended, and Chapter 13.06 of the Port Angeles
Municipal Code relating to industrial wastewater are hereby amended by amending
Chapter 13.06 as follows:
CHAPTER 13.06 - INDUSTRIAL WASTEWATER PRETREATMENT
13.06.030 - Discharge prohibitions.
The following discharges are prohibited:
A. No user shall introduce or cause to be introduced into the POTW any pollutant or
wastewater that causes pass through or interference. These general prohibitions apply to
all users of the POTW whether or not they are subject to categorical pretreatment standards
or any other National, State, or local pretreatment standards or requirements.
B. No user shall introduce or cause to be introduced into the POTW the following
pollutants, substances, or wastewater:
1. Pollutants that either alone or by interaction may create a fire or explosive hazard in
the POTW, a public nuisance or hazard to life, or prevent entry into the sewers for their
maintenance and repair or are in any way injurious to the operation of the system or
operating personnel. This includes waste streams with a closed -cup flashpoint of less than
140 degrees F (60 degrees C) using the test methods specified in 40 CFR 261.21, or its
successors.
2. Any soluble waste or wastes having a pH lower than 5.0 or higher than 4-0-11.0 or
having any other corrosive property that reasonably could be hazardous to structures,
equipment, or personnel of the City, such as, but not limited to, battery or plating acids and
wastes, copper sulfate, chromium salts and compounds, or salt brine.
3. Solid or viscous substances in amounts that may cause obstruction to the flow in the
sewer or other interference with the operation of the system. In no case shall solids greater
than one-quarter inch (0.64 cm) in any dimension be discharged.
4. Pollutants, including oxygen -demanding pollutants (BOD, etc.), released in a
discharge at a flow rate and/or pollutant concentration that, either singly or by interaction
with other pollutants, will cause interference with the POTW.
n
5. Wastewater having a temperature that will interfere with the biological activity in the
system, has detrimental effects on the collection system, or prevents entry into the sewer.
In no case shall wastewater be discharged that causes the wastewater temperature at the
treatment plant to exceed 104 degrees F (40 C).
6. Petroleum oil, non -biodegradable cutting oil, or products of mineral oil origin, in
amounts that will cause pass through or interference.
7. Pollutants that result in the presence of toxic gases, vapors, or fumes within the POTW
in a quantity that may cause acute worker health and safety problems.
8. Trucked or hauled pollutants, except at discharge points designated by the Director in
accordance with section 13.06.051 of this chapter.
9. Noxious or malodorous liquids, gases, solids, or other wastewater that either singly or
by interaction with other wastes, are sufficient to create a public nuisance or a hazard to
life, or to prevent entry into the sewers for maintenance or repair.
10. Wastewater that imparts color that cannot be removed by the treatment process, such
as, but not limited to, dye wastes and vegetable tanning solutions, that consequently imparts
color to the treatment plant's effluent, thereby violating the City's NPDES permit.
11. Wastewater containing any radioactive wastes or isotopes except in compliance with
applicable State or Federal regulations.
12. Wastewater causing, alone or in conjunction with other sources, the treatment plant's
effluent to fail toxicity test.
13. Detergents, surface-active agents, or other substances that may cause excessive
foaming in the POTW.
14. Wastewater causing two readings on an explosion hazard meter at the point of
discharge into the POTW, or at any point in the POTW, of more than ten percent or any
single reading over 20 percent of the lower explosive limit based on an explosivity meter
reading.
C. The following classes of discharge are prohibited unless approved by the Director
because of extraordinary circumstances, such as lack of direct discharge alternatives due
to combined sewer service or need to augment sewage flows due to septic conditions:
Noncontact cooling water in significant volumes.
2. Stormwater, or other direct inflow sources.
3. Wastewaters significantly affecting system hydraulic loading that do not require
treatment or would not be afforded a significant degree of treatment by the system.
4. New discharges of stormwater, surface water, groundwater, artesian well water, roof
runoff, subsurface drainage, condensate, deionized water, noncontact cooling water, and
unpolluted wastewater, unless specifically authorized by the Director.
5. Sludges, screenings, or other residues from the pretreatment of industrial wastes,
unless specifically authorized by the Director.
6. Medical wastes, except as specifically authorized by the Director in a wastewater
discharge permit.
NO
D. Pollutants, substances, or wastewater prohibited by this section shall not be processed
or stored in such a manner that an unintended discharge to the sanitary sewer or the storm
sewer could occur.
13.06.032 - New construction.
A. Prior to construction of a new FSE or NFD, a building permit shall be obtained
from the appropriate jurisdiction. Plan submittals shall include kitchen fixture plan views
and kitchen waste plans showing all potential grease discharging lines, all GIs, and
connecting piping. The application shall be routed to the Director or his designee for review
and approval prior to connecting new construction to the POTW.
B. All new single occupancy food service establishment buildings shall be constructed
with properly sized gFease-ifAefeeptofsGQls. All kitchen drains and any other drains that
may carry grease -laden waste shall be connected to a GI. A dishwasher shall not be
connected to hydro -mechanical Gls. If a P-arbage disposal/garbage
grinder/macerator or similar unit is installed in -a kitchen it must discharge to the GI
through a solids interceptor plumbed immediatelv after the garbage disposal/parba e
grinder/macerator or similar unit The solids interc ptor shall be maintained in proper
operating condition at all times. if a hydfo fneehanical G! is installed, the kitchen may no
C. All new construction, multiple occupancy, and food service establishment
buildings, shall include a separate waste line for all leasable spaces that discharge to a
common 2,000 gallon or larger interceptor. This waste line shall be permanently marked
to identify it as required by the Director. When a space is leased, sold, or rented to a FSE
or NFD, all kitchen drains and any other drains that may carry grease -laden waste shall be
connected to this waste line, no domestic sewage may be connected to this line. The
property owner shall be responsible for proper maintenance of this interceptor in
accordance with the provisions of this chapter.
D. All new single occupancy NFD buildings shall install a properly sized GI. Gravity
GIs are recommended, but hydro -mechanical GIs are permissible. All kitchen drains and
any other drains that may carry grease -laden waste shall be connected to this GI (except
the dishwasher if a hydro -mechanical GI is installed). If a hydro -mechanical GI is installed,
the kitchen may not have a garbage disposal/garbage grinder/macerator or similar unit
installed.
E. Any FSE or NFD undertaking a substantial remodel will be considered to be new
construction for the purposes of this chapter.
13.06.033 - Existing construction.
A. Every person owning or operating an FSE without a functional GI shall be required
to install a functional GI. The type of GI required will be determined by the Director, taking
into account cost, available space and gradient, and any other pertinent information. Where
feasible, all kitchen drains and any other drains that may carry grease -laden waste shall be.
connected to the GI. Dishwashers shall not be connected to hydro -mechanical grease
interceptors. If a garbage disposal/garbage grinder/macerator or similar unit is installed in
a kitchen, A must discharge to the GI through a solids interceptor plumbed immediately

B. Any existing NFD without a
functional GI may be required to install one. The type of GI required will be determined by
the Director, taking into account cost, available space and gradient, whether the user is in a
grease impact area, and any other pertinent information. Where feasible, all kitchen drains
and any other drains that may carry grease -laden waste shall be connected to this GI (except
the dishwasher if a hydro -mechanical GI is installed). If a hydro -mechanical GI is installed,
the kitchen may not have a garbage disposal/garbage grinder/macerator or similar unit
installed.
13.06.034 - Grease interceptor maintenance.
A. All C;is shall be maintained to ensure proper operation. At a
minimum, gravity GIs shall be cleaned at least once every 90 days and hydro -mechanical
GIs cleaned at least once per week. These required frequencies may be extended with the
approval of the Director. Gee inierveptefsGIs must be cleaned whenever the combined
thickness of the floating greases and settled solids is equal to, or greater than, 25 percent of
the total liquid depth in the GI.
B. When cleaned, a gravity GI must be completely pumped out, all solids removed,
solidified grease scraped from the interior and the structure and all internal plumbing
inspected for damage and corrosion. The gravity GI shall be refilled with water prior to
being placed back into operation. If repairs are required, they shall be performed within
seven days.
C. When cleaned, a tr=ap -hydro -mechanical GI must have surface grease and oil
removed, settled solids removed, all sides scraped, removable parts removed and cleaned,
be inspected for damage and corrosion, and be properly reassembled. If repairs are required,
they shall be performed within seven days.
D. The grease and solids that are removed in the process of cleaning a GI shall not be
discharged back into the GI, any part of the POTW, any private sewer, any drainage piping,
or storm sewer system. All grease and solids removed shall be handled and disposed of in
accordance with Federal, State, County and Local laws, rules and regulations. Treated water
inside a hydro -mechanical GI may be temporarily removed during cleaning and returned
into the hydro -mechanical GI following complete cleaning.
E. In addition to the maintenance required above, automatic grease interceptors shall
be maintained in accordance with the manufacturers' guidelines.
13.06.035 - Grease interceptor additives.
No additive may be introduced to the plumbing system that would reduce the effectiveness
of the GI.

roo
13.06.041 - National Categories! Pretreatment Standards.
The ea+—.4eal-pretreatment standards found at 40 CFR Chapter I, Subchapter N, Parts
49-5403-471, and its successors, are incorporated herein by this reference.
A. Where a eategefieal-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 sections
13.06.041(D)(3) and (E) (see 40 CFR 403.6(c)).
B. When eateger-ieal-pretreatment standards are expressed in terms of a mass of
pollutant that may be discharged per unit of production, the Director may either impose
limits based on mass or equivalent effluent concentrations. The user must supply
appropriate actual or projected long term production rates for the unit of production
specified in order to facilitate this process (see 40 CFR 403.6(c)(2)).
C. The Director may permit wastewater subject to a categorical pretreatment standard
to be mixed with other wastewaters prior to treatment. In such cases, the user shall identify
all categorical waste streams and provide sufficient information on each non -categorical
waste stream to determine whether it should be considered dilute for each pollutant. Absent
information showing that non -categorical waste streams contain the pollutant in question at
levels above that of the supply water, such waste streams shall be considered dilute. In such
situations, the Director shall apply the combined waste stream formula as found at 40 CFR
403.6(e), and its successors, to determine appropriate limits.
D. When a eatege pretreatment standard is expressed only in terms of pollutant
concentrations, an industrial user may request that the City convert the limits to equivalent
mass limits.
13.06.044 - Dilution.
No user shall increase the use of process water, or in any way attempt to dilute a discharge,
as a partial or complete substitute for adequate treatment to achieve compliance with a
discharge limit, unless expressly authorized by an applicable pretreatment standard or
requirement. The Director may impose equivalent mass limitations on users where deemed
appropriate to safeguard against the use of dilution to meet applicable pretreatment
standards or requirements, or in other cases when the imposition of equivalent mass
limitations in lieu of or in addition to concentration based limitations is appropriate.
13.06.170 - Supplemental enforcement action.
A. Penalties for late reports. The Director may assess a penalty of $100.00 to any user
for each day that a report required by this chapter, a permit or order issued hereunder is late.
Penalties accrue beginning the fifth day after the report is due. The Director's actions to
collect late reporting penalties shall not limit the Director's authority to initiate any other
enforcement action.
B. Performance bonds. The Director may require a satisfactory bond, payable to the
City, in a sum not to exceed a value determined by the Director as necessary to assure the
user will achieve consistent compliance with this chapter. The Director may require this
bond as an enforcement response or as a prerequisite to issue or reissue a wastewater
discharge permit. Any user who has failed to comply with any provision of this chapter, a
previous permit or order issued hereunder, or any other pretreatment standard or
requirement may be subject to this requirement.
This bond may also be required of any category of user which has ted to public burdens in
the past regardless of the compliance history of the particular user. The City may use this
bond to pay any fees, costs, or penalties assessed to the user whenever the user's account is
in arrears for over 30 days. This includes the costs of cleanup of the site if the user goes out
of business, sells the business to a person that does not first assume the bond, or goes
bankrupt. Users may petition the Director to convert their performance bond to a
requirement to provide liability insurance, or to forego any such safeguard based on their
performance. User may petition no more frequently than once in any 12 -month period.
C. Liability insurance. The Director may require a user to provide insurance if it
previously failed to comply with any provision of this chapter, a previous permit, or order
issued hereunder, or any other pretreatment standard or requirement. The Director may also
require users in businesses which historically have left a public burden to clean up pollution
to obtain this insurance, regardless of their compliance history. In such cases, users must
provide proof that the insurance is sufficient to cover any liabilities incurred under this
chapter, including the cost of damages to the POTW and the environment caused by the
user. The Director may require users to provide the proof of such insurance either in
response to noncompliance or prior to issuing or reissuing a wastewater discharge permit.
D. Payment of outstanding gees -fees and penalties. The Director may decline to issue
or reissue a wastewater discharge permit to any user who has failed to pay any outstanding
fees, fines or penalties incurred as a result of any provision of this chapter, a previous permit
or order issued hereunder.
E. Water supply severance. The Director may order water service to a user severed
whenever a user has violated or continues to violate any provision of this chapter, a permit,
or order issued hereunder, or any other pretreatment standard or requirement. Users wishing
to restore their service must first demonstrate their ability to comply with this chapter and
pay the related costs of this action.
Section 2 - Corrections. The City Clerk and the codifiers of this ordinance are
authorized to make necessary corrections to this ordinance including, but not
limited to, the correction of the scrivener's/clerical errors, references to other local, state, or
federal laws, codes, rules or regulations, or ordinance numbering, section/subsection numbers
and any references thereto.
