This chapter sets forth uniform requirements for users of the
publicly owned treatment works for the city of Crescent City and enables
the city to comply with all applicable state and federal laws, including
the Clean Water Act (33 United States Code [USC] Section 1251 et seq.)
and the General Pretreatment Regulations (Title 40 of the Code of
Federal Regulations [CFR] Part 403). The objectives of this chapter
are:
A. To
prevent the introduction of pollutants into the publicly owned treatment
works that will interfere with its operation;
B. To
prevent the introduction of pollutants into the publicly owned treatment
works that will pass through the publicly owned treatment works, inadequately
treated, into receiving waters, or otherwise be incompatible with
the publicly owned treatment works;
C. To
protect both publicly owned treatment works personnel who may be affected
by wastewater and sludge in the course of their employment and the
general public;
D. To
promote reuse and recycling of industrial wastewater and sludge from
the publicly owned treatment works;
E. To
provide for fees for the equitable distribution of the cost of operation,
maintenance, and improvement of the publicly owned treatment works;
and
F. To
enable the city to comply with its National Pollutant Discharge Elimination
System permit conditions, sludge use and disposal requirements, and
any other federal or state laws to which the publicly owned treatment
works is subject.
This chapter applies to all users of the publicly owned treatment
works. The chapter authorizes the issuance of individual wastewater
discharge permits or general permits; provides for monitoring, compliance,
and enforcement activities; establishes administrative review procedures;
requires user reporting; and provides for the setting of fees for
the equitable distribution of costs resulting from the program established
in this chapter.

imposed upon the pretreatment coordinator may be delegated by the
pretreatment coordinator to a duly authorized city of Crescent City
employee.

portion of a user's pretreatment facility.
"Categorical Pretreatment Standard" or Categorical Standard"
means any regulation containing pollutant discharge limits
promulgated by EPA in accordance with Section 307(b) and (c) of the

of sampling (as specified in the permit), for a constituent with limitations
expressed in units of mass; or (2) the unweighted arithmetic mean
measurement of the constituent over the day for a constituent with
limitations expressed in other units of measurement (e.g., concentration).
"Daily maximum"

limitation are the same and require the same or similar monitoring
and in the opinion of the pretreatment coordinator, are more appropriately
controlled under a general permit than under individual wastewater
discharge permits.
"Grab sample"
means a sample that is taken from a waste stream without
regard to the flow in the waste stream and over a period of time not
to exceed fifteen minutes.
"Gray water"

rate and the duration of the sampling event.
"Interference"
means a discharge that, alone or in conjunction with a discharge
or discharges from other sources, inhibits or disrupts the POTW, its
treatment processes or operations or its sludge processes, use or
disposal and therefore, is a cause of a violation of the city's NPDES
permit or of the prevention of sewage sludge use or disposal in compliance
with any of the following statutory/regulatory provisions or any permits
issued thereunder, or any more stringent state or local regulations:
Section 405 of the Act; the Solid Waste Disposal Act, including Title
II commonly referred to as the Resource Conservation and Recovery
Act (RCRA); any state regulations contained in any state sludge management

means:
1.
Any building, structure, facility, or installation from which
there is (or may be) a discharge of pollutants, the construction of
which commenced after the publication of proposed Pretreatment Standards
under Section 307(c) of the Act that will be applicable to such source
if the Pretreatment Standards are thereafter promulgated in accordance
with that section, if:
a.
The building, structure, facility, or installation is constructed
at a site at which no other source is located; or
b.
The building, structure, facility, or installation totally replaces
the process or production equipment that causes the discharge of pollutants
at an existing source; or
c.
The production or wastewater-generating processes of the building,
structure, facility, or installation are substantially independent
of an existing source at the same site. In determining whether these
are substantially independent, factors such as the extent to which
the new facility is integrated with the existing plant, and the extent
to which the new facility is engaged in the same general type of activity
as the existing source, must be considered.
2.
Construction on a site at which an existing source is located
results in a modification rather than a new source if the construction
does not create a new building, structure, facility, or installation
meeting the criteria of paragraph (1)(b) or (c) above but otherwise
alters, replaces, or adds to existing process or production equipment.
3.
Construction of a new source as defined under this paragraph
has commenced if the owner or operator has:

be terminated or modified without substantial loss, and contracts
for feasibility, engineering, and design studies do not constitute
a contractual obligation under this paragraph.

means water used for cooling that does not come into direct
contact with any raw material, intermediate product, waste product,
or finished product.
"Non-significant categorical industrial user"
means an industrial user that never discharges more than

The industrial user, prior to the city's finding, has consistently
complied with all applicable Categorical Pretreatment Standards and
Requirements;
2.

13.40.450(B), together with any additional information necessary to support the certification statement; and
3.
The industrial user never discharges any untreated concentrated
wastewater.
"Pass through"
means a discharge that exits the POTW into waters of the

with a discharge or discharges from other sources, is a cause of a
violation of any requirement of the city's NPDES permit, including
an increase in the magnitude or duration of a violation.

212 of the Act (33 USC Section 1292), which is owned by the city.
This definition includes any devices or systems used in the collection,
storage, treatment, recycling, and reclamation of sewage or industrial
wastes of a liquid nature and any conveyances, which convey wastewater
to a treatment plant.
"Pretreatment"
means the reduction of the amount of pollutants, the elimination
of pollutants, or the alteration of the nature of pollutant properties
in wastewater prior to, or in lieu of, introducing such pollutants
into the POTW. This reduction or alteration can be obtained by physical,
chemical, or biological processes, by process changes, or by other
means, except by diluting the concentration of the pollutants unless
that is allowed by an applicable Pretreatment Standard.
"Pretreatment coordinator"

operation of the POTW and who is charged with certain duties and responsibilities
by this chapter, as well as a duly authorized representative designated
in writing by the pretreatment coordinator.

b.
Contributes a process wastestream which makes up five percent
or more of the average dry weather hydraulic or organic capacity of
the POTW treatment plant, or
c.
Is designated as such by the city on the basis that it has a
reasonable potential for adversely affecting the POTW's operation
or for violating any Pretreatment Standard or Requirement;
3.
The city may determine that an industrial user subject to Categorical
Pretreatment Standards is a non-significant categorical industrial
user rather than a significant industrial user;
4.
Upon a finding that a user meeting the criteria in paragraph
2 of this definition has no reasonable potential for adversely affecting
the POTW's operation or for violating any Pretreatment Standard or
Requirement, the city may at any time, on its own initiative or in
response to a petition received from an Industrial user, and in accordance
with procedures in 40 CFR 403.8(f)(6), determine that such user should
