treatment works that will pass through the publicly owned treatment
works, inadequately treated, into receiving water, or otherwise be
incompatible with the publicly owned treatment works;
(3)
To protect publicly owned treatment works personnel who may be affected
by wastewater and sludge in the course of their employment and to
protect the general public;
(4)
To improve the opportunity to recycle and reclaim wastewater and
sludge from the publicly owned treatment works;
(5)
To provide for fees for the equitable distribution of the cost of
operation, maintenance, and improvement of the publicly owned treatment
works; and
(6)
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.
(b)

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 which will be applicable to such source
if such standards are thereafter promulgated in accordance with that
section, provided that:
The building, structure, facility, or installation is constructed
at a site at which no other source is located;
The building, structure, facility, or installation totally replaces
the process or production equipment that causes the discharge of pollutants
at an existing source; or
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, should be considered.
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

is necessary for the placement, assembly, or installation of new source
facilities or equipment; or
Entered into a binding contractual obligation for the purchase
of facilities or equipment that are intended to be used in its operation
within a reasonable time. Options to purchase or contract which can
be terminated or modified without substantial loss, and contracts
for feasibility, engineering, and design studies do not constitute
a contractual obligation under this subsection.

over any 24-hour period;
The concentration of free or emulsified animal oil, vegetable
oil or grease (FOG) will not exceed one hundred milligrams per liter
(100 mg/l); and
The concentration of total petroleum hydrocarbons (TPH) will
not exceed twenty milligrams per liter (20 mg/l).
A discharge which exits the POTW into water of the United
States in quantities or concentration which, alone or in conjunction
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).

(COD), toxicity, odor).
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
allowed by an applicable pretreatment standard).
Any substantive or procedural requirement related to pretreatment
imposed on a user, other than a pretreatment standard.
As defined in 40 CFR 403.3(j) or as approved by the EPA.

The above limits apply at the point where the wastewater
is discharged to the POTW. All concentrations for metallic substances
are for “total” metal unless indicated otherwise. The
director may impose mass limitations in addition to, or in place of,
the concentration-based limitations above.
(e)
City’s right of revision.
The city reserves the
right to establish, by ordinance or in wastewater discharge permits,
more stringent standards or requirements on discharges to the POTW.
(f)
Special agreement.
The city reserves the right to enter
into special agreements with users, setting out special terms under
which they may discharge to the POTW. A user may request a net gross
adjustment to a categorical standard in accordance with 40 CFR 403.15.
A user also may request a variance from the categorical pretreatment
standard from the approval authority. Such a request will be approved
only if the user can prove that factors relating to its discharge
are fundamentally different from the factors considered by the EPA
when establishing that categorical pretreatment standard. A user requesting
a fundamentally different factor variance must comply with the procedural
and substantive provisions in 40 CFR 403.13.
(g)
Dilution.
No user shall ever 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 limitation unless expressly authorized by an applicable
pretreatment standard or requirement. The director may impose mass
limitations on users who are using dilution to meet applicable pretreatment
standards or requirements, or in other cases when the imposition of
mass limitations is appropriate.
(Ordinance 2010-002, sec. II, adopted 2/16/10)
(a)
Pretreatment facilities.
Users shall provide wastewater treatment as necessary to comply with this division and shall achieve compliance with all categorical pretreatment standards, local limits, and the prohibitions set out in section 12.03.035(a) of this division within the time limitations specified by the EPA, the state, or the director, whichever is more stringent. Any facilities necessary for compliance shall be provided, operated, and maintained at the user’s expense. Detailed plans describing such facilities and operation procedures shall be submitted to the director for review, and shall be acceptable to the director before such facilities are constructed. The review of such plans and operating procedures shall in no way relieve the user from the responsibility of modifying such facilities as necessary to produce a discharge acceptable to the director under the provisions of this division.
(b)
Grease, oil and sand traps, catch basins, interceptors or hold-haul
tanks; additional pretreatment measures.
(1)
Grease, oil and sand traps, catch basins, interceptors or hold-haul
tanks shall be provided for the proper handling of waste containing
grease in excessive amounts, sand and other prohibited materials;
however, interceptors, traps and catch basins are not required for
private living quarters or dwellings. All interceptors, traps and
catch basins shall meet the city plumbing code as filed in the code
administration. The code may be revised from time to time as necessary.
All interceptors, traps and catch basins shall be located so as to
be readily and easily accessible for cleaning and inspection. Grease
and oil interceptors shall be constructed of impervious materials
capable of withstanding abrupt and extreme changes in temperature.
They shall be of substantial construction and equipped with easily
removable covers or grates. Where installed, all grease, oil and sand
traps and/or interceptors shall be maintained by the owner or occupant
at his own expense and in continuously efficient operation. Hold-haul
tanks shall not be connected to the sanitary sewer.
Materials removed from these facilities shall be either utilized
by industry or disposed of at approved locations. All fixtures draining
to interceptors, traps and/or catch basins shall be rated as specified
in the city plumbing code.
(2)
Use of hot water, enzymes, chemicals, other agents or devices for
the purpose of causing the oil, grease, or sand to pass through the
trap, interceptor, or any other such facility provided is prohibited.
(3)
Carwash facilities, service stations and similar installations.
All wash facilities shall be protected from rain and runoff.
(4)
Machine shop, garages, special manufacturing facilities.
Drainage from the work area of machine shops or of any industry that
manufactures, rebuilds or overhauls motors, engines, transmissions,
hydraulic systems or similar machinery may be discharged to the sanitary
sewer only if the effluent can meet all the requirements of this division.
(5)
Steam cleaning and chemical cleaning facilities.
Drainage
from steam cleaning and/or chemical cleaning facilities shall not
be discharged to the sanitary sewer unless a facility or process is
provided that will consistently and constantly produce an effluent
containing no hazardous waste or other pollutant that will cause pass-through
or interference.
(6)
Any sewer line stoppage, damage or restriction of flow caused by
an illegal discharge shall be considered a violation of this division
and the person or persons responsible will be held liable.
(7)
Whenever deemed necessary, the director may require users to restrict
their discharge during peak flow periods, designate that certain wastewater
be discharged only into specific sewers, relocate and/or consolidate
points of discharge, separate sewage wastestreams from industrial
wastestreams, and such other conditions as may be necessary to protect
the POTW and determine the user’s compliance with the requirements
of this division.
(8)
The director may require any person discharging into the POTW to
install and maintain, on their property and at their expense, a suitable
storage and flow-control facility to ensure equalization of flow.
A wastewater discharge permit may be issued solely for flow equalization.
(9)
Users with the potential to discharge flammable substances may be
required to install and maintain an approved combustible gas detection
meter.
(c)
Accidental discharge/slug control plans.
At least once
every two (2) years the director shall evaluate whether each significant
industrial user needs an accidental discharge/slug control plan. The
director may require any user to develop, submit for approval, and
implement such a plan. Alternatively, the director may develop such
a plan for any user. An accidental discharge/slug control plan shall
address, at a minimum, the following:
(1)
Description of discharge practices, including nonroutine batch discharges;
(2)
Description of stored chemicals;
(3)
Procedures for immediately notifying the POTW of any accidental or slug discharge, as required by section 12.03.039(f) of this division; and
(4)
Procedures to prevent adverse impact from any accidental or slug
discharge. Such procedures include, but are not limited to, inspection
and maintenance of storage areas, handling and transfer of materials,
loading and unloading operations, control of plant site runoff, worker
training, building of containment structures or equipment, measures
for containing toxic organic pollutants (including solvents), and/or
measures and equipment for emergency response.
(d)
Hauled waste and wastewater.
(1)
No waste hauler may discharge any industrial waste or wastewater,
septic tank waste, chemically treated human waste, and/or any trap
waste into the POTW without first obtaining a wastewater discharge
permit from the director. The director may prohibit the discharge
of any such hauled industrial waste. The director also may issue wastewater
discharge permits to any generators of hauled industrial waste discharged.
The discharge of hauled waste is subject to all other requirements
of this division.
(2)
Waste haulers may discharge loads only at locations designated by
the director. No load may be discharged without prior consent of the
director. The director may collect samples of each hauled load to
ensure compliance with applicable standards. The director may require
the waste hauler to provide a waste analysis of any load prior to
discharge.
(3)
Industrial waste haulers who discharge any industrial waste or wastewater
into the POTW must provide a waste-tracking form for every load. This
form shall include, at a minimum, the name and address of the industrial
waste hauler, permit number, truck identification, names and addresses
of sources of waste, and volume and characteristics of waste. The
form shall identify the type of industry, known or suspected waste
constituents, and whether any wastes are RCRA hazardous wastes. The
director may require such waste-tracking forms to be provided by haulers
of nonindustrial trap waste, septic tank waste, or chemically treated
human waste that is discharged into the POTW.
(4)
Any person hauling industrial waste or wastewater, septic tank waste,
chemically treated human waste, and/or trap waste generated within
the city limits that is not discharged into the POTW must provide
written notice of such waste hauling to the director specifying, at
a minimum, the name and address of the waste hauler and the location
at which the waste is disposed of. The director may prohibit disposal
within the city of any such hauled waste.

All periodic compliance reports must be signed and certified in accordance with section 12.03.037(g) of this division.
(2)
All wastewater samples must be representative of the user’s
discharge. Wastewater monitoring and flow measurement facilities shall
be properly operated, kept clean, and maintained in good working order
at all times. The failure of a user to keep its monitoring facility
in good working order shall not be grounds for the user to claim that
sample results are unrepresentative of its discharge.
(e)
Reports of changed conditions.
Each user must notify
the director of any planned significant changes to the user’s
operations or system which might alter the nature, decrease the quality,
or increase the volume of its wastewater at least ninety (90) days
before the change.
(1)
The director may require the user to submit such information as may be deemed necessary to evaluate the changed condition, including the submission of a wastewater discharge permit application under section 12.03.037(f) of this division.
(2)
The director may issue a wastewater discharge permit under section 12.03.037(h) of this division, or modify an existing wastewater discharge permit under section 12.03.038(d) of this division in response to changed conditions or anticipated changed conditions.

but are not limited to, flow increases of twenty-five percent (25%)
or greater, and the discharge of any previously unreported pollutants.
(f)
Reports of potential problems.
(1)
In the case of any discharge, including, but not limited to, accidental
discharges, discharges of a nonroutine, episodic nature, a noncustomary
batch discharge, or a slug load that may cause potential problems
for the POTW, the user shall immediately telephone and notify the
director of the incident. This notification shall include the location
of the discharge, type of waste, concentration and volume (if known),
and corrective actions taken by the user.
(2)
Within five (5) days following such discharge, the user shall, unless
waived by the director, submit a detailed written report describing
the cause(s) of the discharge and the measures taken by the user to
prevent similar future occurrences. Such notification shall not relieve
the user of any expense, loss, damage, or other liability which may
be incurred as a result of damage to the POTW, natural resources,
or any other damage to person or property; nor shall such notification
relieve the user of any fines, penalties, or other liability which
may be imposed pursuant to this division.
(3)
Failure to notify the director of potential problem discharges shall
be deemed a violation of this division.
(4)
A notice shall be permanently posted on the user’s bulletin board or other prominent place advising employees whom to call in the event of a discharge described in subsection (1) above. Employers shall ensure that all employees who may cause such a discharge to occur are advised of the emergency notification procedure.
(g)
Reports from unpermitted users.
All users not required
to obtain a wastewater discharge permit shall provide appropriate
reports to the director as the director may require.
(h)
Notice of violation/repeat sampling and reporting.
If
sampling performed by a user indicates a violation, the user must
notify the director within twenty-four (24) hours of becoming aware
of the violation. The user shall also repeat the sampling and analysis
and submit the results of the repeat analysis to the director within
thirty (30) days after becoming aware of the violation.
(i)
Notification of the discharge of hazardous waste.
(1)
Any user who commences the discharge of hazardous waste shall notify the POTW, the EPA Regional Waste Management Division Director, and state hazardous waste authorities, in writing, of any discharge into the POTW of a substance which, if otherwise disposed of, would be a hazardous waste under 40 CFR part 261. Such notification must include the name of the hazardous waste as set forth in 40 CFR part 261, the EPA hazardous waste number, and the type of discharge (continuous, batch, or other). If the user discharges more than one hundred (100) kilograms of such waste per calendar month to the POTW, the notification also shall contain the following information to the extent such information is known and readily available to the user: an identification of the hazardous constituents contained in the wastes, an estimation of the mass of and concentration of such constituents in the wastestream expected to be discharged during the following twelve (12) months. All notifications must take place no later than one hundred eighty (180) days after the discharge commences. Any notification under this subsection need be submitted only once for each hazardous waste discharged. However, notifications of changed conditions must be submitted under subsection (e) of this section. The notification requirement in this section does not apply to pollutants already reported by users subject to categorical pretreatment standards under the self-monitoring requirements of subsections (a), (c) and (d) of this section.
(2)
Dischargers are exempt from the requirements of subsection (1) above, during a calendar month in which they discharge no more than fifteen (15) kilograms of hazardous wastes, unless the wastes are acute hazardous wastes as specified in 40 CFR 261.30(d) and 261.33(e). Discharge of more than fifteen (15) kilograms of nonacute hazardous wastes in a calendar month, or of any quantity of acute hazardous wastes as specified in 40 CFR 261.30(d) and 261.33(e), requires a one-time notification. Subsequent months during which the user discharges more than such quantities of any hazardous waste do not require additional notification.
(3)
In the case of any new regulations under section 3001 of RCRA, identifying
additional characteristics of hazardous waste or listing any additional
substance as a hazardous waste, the user must notify the director,
the EPA Regional Waste Management Waste Division Director, and state
hazardous waste authorities of the discharge of such substance within
ninety (90) days of the effective date of such regulations.
(4)
In the case of any notification made under this section, the user
shall certify that it has a program in place to reduce the volume
and toxicity of hazardous wastes generated to the degree it has determined
to be economically practical.
(5)
This provision does not create a right to discharge any substance
not otherwise permitted to be discharged by this division, a permit
issued hereunder, or any applicable federal or state law.
(j)
Analytical requirements.
All pollutant analyses, including
sampling techniques, to be submitted as part of a wastewater discharge
permit application or report shall be performed in accordance with
the techniques prescribed in 40 CFR part 136, unless otherwise specified
in an applicable categorical pretreatment standard. If 40 CFR part
136 does not contain sampling or analytical techniques for the pollutant
in question, sampling and analyses must be performed in accordance
with procedures approved by the director.
(k)
Sample collection.
(1)
Except as indicated in subsection (2), below, the user must collect wastewater samples using flow proportional composite collection techniques. In the event flow proportional sampling is infeasible, the director may authorize the use of time proportional sampling or a minimum of four (4) grab samples where the user demonstrates that this will provide a representative sample of the effluent being discharged. In addition, grab samples may be required to show compliance with instantaneous discharge limits.
(2)
Samples for oil and grease, temperature, pH, cyanide, phenols, sulfides,
and volatile organic chemicals must be obtained using grab collection
techniques.
(l)
Timing.
Written reports will be deemed to have been
submitted on the date postmarked. For reports that are not mailed
postage prepaid into a mail facility serviced by the United States
Postal Service, the date of receipt of the report shall govern.
(m)
Recordkeeping.
Users subject to the reporting requirements
of this division shall retain, and make available for inspection and
copying, all records of information obtained pursuant to any monitoring
activities required by this division and any additional records of
information obtained pursuant to monitoring activities undertaken
by the user independent of such requirements. Records shall include
the date, exact place, method, and time of sampling and the name of
the person(s) taking the samples; the dates analyses were performed;
who performed the analyses; the analytical techniques or methods used;
the results of such analyses; and all QA/QC data required by permit.
These records shall be available for a period of at least three (3)
years. This period shall be automatically extended for the duration
of any litigation concerning the user or the city, or where the user
has been specifically notified of a longer retention period by the
director.
(Ordinance 2010-002, sec. VI, adopted 2/16/10)
(a)
Right of entry: inspection and sampling.
The director
shall have the right to enter the premises of any user to determine
whether the user is complying with all requirements of this division,
and any wastewater discharge permit or order issued hereunder. The
owners and occupants of premises where industrial waste is created
or discharged into a sanitary sewer shall allow the director, his
inspectors, agents, and representatives ready access at any time necessary
to all parts of such premises for purposes of inspection, sampling,
characterizing the waste, setting up and using monitoring equipment,
inspecting and copying records, and the performance of any of their
duties; and the failure or refusal of such owners or occupants to
comply with these provisions shall be grounds for the disconnection
of water or sewer service or both.
(1)
Where a user has security measures in force which require proper
identification and clearance before entry into its premises, the user
shall make necessary arrangements with its security guards so that,
upon presentation of suitable identification, the director will be
permitted to enter without delay for the purposes of performing specific
responsibilities.
(2)
The director shall have the right to set up on the user’s property,
or require installation of, such devices as are necessary to conduct
sampling and/or metering of the user’s operations.
(3)
The director may require the user to install monitoring equipment
as necessary. The facility’s sampling and monitoring equipment
shall be maintained at all times in a safe and proper operating condition
by the user at its own expense. All devices used to measure wastewater
flow shall be calibrated yearly to ensure their accuracy. Instruments
used to measure quality shall be calibrated as per accepted EPA QA/QC
protocol.
(4)
Any temporary or permanent obstruction to safe and easy access to
the facility to be inspected and/or sampled shall be promptly removed
by the user at the written or verbal request of the director and shall
not be replaced. The costs of clearing such access shall be borne
by the user.
(5)
Unreasonable delays in allowing the director access to the user’s
premises shall be a violation of this division.
(6)
Determining the character and concentration of industrial waste.
The industrial waste discharged or deposited into a sanitary sewer shall be subject to inspection and sampling as often as may be deemed necessary by the director, but at least annually. In determining the surcharge to be made, samples shall be collected in such manner as to be representative of the character and concentration of the waste under operational conditions. The laboratory methods used in the examination and analysis of the samples shall be in accordance with the techniques and procedures required by section 12.03.039(j) of this division. The sampling schedule for determining the character and concentration of industrial waste shall be made by the director at such times and on such basis as he may reasonably establish. Should the owner or occupant discharging industrial waste into a sanitary sewer desire that a determination of the quality of such industrial waste be made at some time other than that scheduled by the director, such special determination may be made by the director at the expense of the owner or occupant discharging the waste.
(b)
Search warrants.
If the director has been refused access
to a building, structure or property, or any part thereof, and is
able to demonstrate probable cause to believe that there may be a
violation of this division, or that there is a need to inspect and/or
sample as part of a routine inspection and sampling program of the
city, designed to verify compliance with this division or any permit
or order issued hereunder, or to protect the overall public health,
safety and welfare of the community, then the director may seek issuance
of a search warrant from any court of competent jurisdiction.
(Ordinance 2010-002, sec. VII, adopted 2/16/10)
Information and data on a user obtained from reports, surveys,
wastewater discharge permit application, wastewater discharge permits,
and monitoring programs, and from the director’s inspection
and sampling activities, shall be available to the public without
restriction, unless the user specifically requests, and is able to
demonstrate to the satisfaction of the director, that the release
of such information would divulge information, processes or methods
of production entitled to protection as trade secrets under applicable
state law. Any such request must be asserted at the time of submission
of the information or data. When requested and demonstrated by the
user furnishing a report that such information should be held confidential,
the portions of a report which might disclose trade secrets or secret
processes shall not be made available for inspection by the public,
but shall be made available immediately upon request to governmental
agencies for uses related to the NPDES program or pretreatment program,
and in enforcement proceedings involving the person furnishing the
report. Wastewater constituents and characteristics and other “effluent
data” as defined by 40 CFR 2.302 will not be recognized as confidential
information and will be available to the public without restriction.
(Ordinance 2010-002, sec. VIII,
adopted 2/16/10)
The director shall publish annually, in the largest daily newspaper
published in the city, a list of the users which, during the previous
twelve (12) months, were in significant noncompliance with applicable
pretreatment standards and requirements. The term significant noncompliance
shall mean:
(1)
Chronic violations of wastewater discharge limits, defined here as
those in which sixty-six percent (66%) or more of wastewater measurements
taken during a six-month period exceed the daily maximum limit or
average limit for the same pollutant parameter by any amount;
(2)
Technical review criteria (TRC) violations, defined here as those
in which thirty-three percent (33%) or more of wastewater measurements
taken for each pollutant parameter during a six-month period equals
or exceeds the product of the daily maximum limit or the average limit
multiplied by the applicable criteria (1.4 for BOD, TSS, fats, oils
and grease, and 1.2 for all other pollutants except pH);
(3)
Any other discharge violation that the director believes has caused,
alone or in combination with other discharges, interference or pass-through,
including endangering the health of POTW personnel or the general
public;
(4)
Any discharge of pollutants that has caused imminent endangerment
to the public or to the environment, or has resulted in the director’s
exercise of its emergency authority to halt or prevent such a discharge;
(5)
Failure to meet, within ninety (90) days of the scheduled date, a
compliance schedule milestone contained in a wastewater discharge
permit or enforcement order for starting construction, completing
construction, or attaining final compliance;
(6)
Failure to provide within thirty (30) days after the due date, any
required reports, including baseline monitoring reports, reports on
compliance with categorical pretreatment standard deadlines, periodic
self-monitoring reports, and reports on compliance with compliance
schedules;
(7)
Failure to accurately report noncompliance; or
(8)
Any other violations(s) that the director determines will adversely
affect the operation or implementation of the local pretreatment program.
(Ordinance 2010-002, sec. IX, adopted 2/16/10)
(a)
Notification of violation.
When the director finds that
a user has violated, or continues to violate, any provision of this
division, a wastewater discharge permit, or order issued hereunder,
or any other pretreatment standard or requirement, the director may
serve upon that user a written notice of violation. Within ten (10)
days of the receipt of this notice, an explanation of the violation
and a plan for the satisfactory correction and prevention thereof,
to include specific required action, shall be submitted by the user
to the director. If the user denies that any violation occurred and/or
contends that no corrective action is necessary, an explanation of
the basis of any such denial or contention shall be submitted to the
director within ten (10) days of receipt of the notice. Submission
of an explanation and/or plan in no way relieves the user of liability
for any violations occurring before or after receipt of the notice
of violation. Nothing in this section shall limit the authority of
the director to take any action, including emergency actions or any
other enforcement action, without first issuing a notice of violation.
(b)
Consent orders.
The director may enter into consent order, assurances of voluntary compliance, or other similar documents establishing an agreement with any user responsible for noncompliance. Such documents may include specific action to be taken by the user to correct the noncompliance within a time period specified by the document. Such documents shall have the same force and effect as the administrative orders issued pursuant to subsections (d) and (e) of this section and shall be judicially enforceable.
(c)
Show cause hearing.
The director may order a user which
has violated, or continues to violate, any provision of this division,
a wastewater discharge permit, or order issued hereunder, or any other
pretreatment standard or requirement, to appear before the director
and show cause why the proposed enforcement action should not be taken.
Notice shall be served on the user specifying the time and place for
the meeting, the proposed enforcement action, the reasons for such
action, and a request that the user show cause why the proposed enforcement
action should not be taken. The notice of the meeting shall be served
personally or by registered or certified mail (return receipt requested)
at least ten (10) days prior to the hearing. Such notice may be served
on any authorized representative of the user. A show cause hearing
shall not be a bar against, or prerequisite for, taking any other
action against the user.
(d)
Compliance orders.
When the director finds that a user
has violated, or continues to violate, any provision of this division,
a wastewater discharge permit, or order issued hereunder, or any other
pretreatment standard or requirement, the director may issue an order
to the user responsible for the discharge directing that the user
come into compliance within the specified time limit. If the user
does not come into compliance within the specified time limit, sewer
service may be discontinued unless adequate treatment facilities,
devices, or other related appurtenances are installed and properly
operated. Compliance orders also may contain other requirements to
address the noncompliance, including additional self-monitoring, and
management practices designed to minimize the amount of pollutants
discharged to the sewer. A compliance order may not extend the deadline
for compliance established for a federal pretreatment standard or
requirement, nor does a compliance order relieve the user of liability
for any violation, including any continuing violation. Issuance of
a compliance order shall not be a bar against, or a prerequisite for,
taking any other action against the user.
(e)
Cease and desist orders.
When the director finds that
a user has violated, or continues to violate, any provision of this
division, a wastewater discharge permit, or order issued hereunder,
or any other pretreatment standard or requirement, or that the user’s
past violations are likely to recur, the director may issue an order
to the user directing it to cease and desist all such violations and
directing the user to:
(1)
Immediately comply with all requirements; and
(2)
Take such appropriate remedial or preventive action as may be needed
to properly address a continuing or threatened violation, including
halting operations and/or terminating the discharge. Issuance of a
cease and desist order shall not be a bar against, or a prerequisite
for, taking any other action against the user.
(f)
Emergency suspensions.
The director may immediately
suspend a user’s discharge, after any reasonable notice to the
user that is practical under the circumstances, whenever such suspension
is necessary to stop an actual or threatened discharge which reasonably
appears to present or cause an imminent or substantial endangerment
to the health or welfare of persons. The director may also immediately
suspend a user’s discharge, after notice and opportunity to
respond, that threatens to interfere with the operation of the POTW,
or which presents, or may present, an endangerment to the environment.
(1)
Any user notified of a suspension of its discharge shall immediately stop or eliminate its contribution. In the event of a user’s failure to immediately comply voluntarily with the suspension order, the director may take such steps as deemed necessary, including immediate severance of the sewer connection, to prevent or minimize damage to the POTW, its receiving stream, or endangerment to any individuals. The director may allow the user to recommence its discharge when the user has demonstrated to the satisfaction of the director that the period of endangerment has passed, unless the termination proceedings in subsection (g) of this section are initiated against the user.
(2)
A user that is responsible, in whole or in part, for any discharge presenting imminent endangerment shall submit a detailed written statement, describing the causes of the harmful contribution and the measures taken to prevent any future occurrence, to the director prior to the date of any termination hearing under subsections (c) or (g) of this section.
|
Nothing in this section shall be interpreted as requiring a
hearing prior to any emergency suspension under this section.
|
(g)
Termination of discharge.
In addition to the provisions in section 12.03.038(f) of this division, any user who violates the following conditions is subject to discharge termination:
(1)
Violation of wastewater discharge permit conditions;
(2)
Failure to accurately report the wastewater constituents and characteristics
of its discharge;
(3)
Failure to report significant changes in operations or wastewater
volume, constituents and characteristics prior to discharge;
(4)
Refusal of reasonable access to the user’s premises for the
purpose of inspection, monitoring or sampling; or
(5)
Violation of the pretreatment standards in section 12.03.035 of this division.
|
Such user will be notified of the proposed termination of its discharge and be offered an opportunity to show cause under subsection (c) of this section why the proposed action should not be taken. Exercise of this option by the director shall not be a bar to, or a prerequisite for, taking any other action against the user.
|
(Ordinance 2010-002, sec. X, adopted 2/16/10)
(a)
Injunctive relief.
When the director finds that a user
has violated, or continues to violate, any provision of this division,
a wastewater discharge permit, or order issued hereunder, or any other
pretreatment standard or requirement, the director may petition any
court of competent jurisdiction through the city’s attorney
for the issuance of a temporary or permanent injunction, as appropriate,
which restrains or compels the specific performance of the wastewater
discharge permit, order, or other requirement imposed by this division
on activities of the user. The director may also seek such other action
as is appropriate for legal and/or equitable relief, including a requirement
for the user to conduct environmental redemption. A petition for injunctive
relief shall not be a bar against, or a prerequisite for, taking any
other action against a user.
(b)
Civil penalties.
(1)
A user who has violated, or continues to violate, any provision of
this division, a wastewater discharge permit, or order issued hereunder,
or any other pretreatment standard or requirement shall be liable
to the city for a maximum civil penalty of not more than $1,000.00
per violation, per day. In the case of a monthly or other long-term
average discharge limit, penalties shall accrue for each day during
the period of the violation.
(2)
The city may recover reasonable attorneys’ fees, court costs,
and other expenses associated with enforcement activities, including
sampling and monitoring expenses, and the cost of any actual damages
incurred by the city, as well as civil penalties, in any court of
competent jurisdiction.
(3)
In determining the amount of civil liability, the court shall take
into account all relevant circumstances, including, but not limited
to, the extent of harm caused by the violation, the magnitude and
duration of the violation, any economic benefit gained through the
user’s violation, corrective actions by the user, the compliance
history of the user, and any other factor as justice requires.
(4)
Filing a suit for civil penalties shall not be a bar against, or
a prerequisite for, taking any other action against a user.
(c)
Criminal prosecution.
(1)
A user who has willfully or negligently violated any provision of
this division, a wastewater discharge permit, or order issued hereunder,
or any other pretreatment standard or requirement shall, upon conviction,
be guilty of a misdemeanor, punishable by a fine of not more than
$2,000.00 per violation, per day.
(2)
A user who has willfully or negligently introduced any substance
into the POTW which causes personal injury or property damage shall,
upon conviction, be guilty of a misdemeanor and be subject to a penalty
of not more than $2,000.00 per day of offending discharge. This penalty
shall be in addition to any other cause of action for personal injury
or property damage available under state law.
(3)
A user who knowingly made any false statements, representations,
or certifications in any application, record, report, plan, or other
documentation filed, or required to be maintained, pursuant to this
division, wastewater discharge permit, or order issued hereunder,
or who falsified, tampered with, or knowingly rendered inaccurate
any monitoring device or method required under this division shall,
upon conviction, be punished by a fine of not more than $2,000.00
per violation, per day.
(d)
Remedies nonexclusive.
The remedies provided for in
this division are not exclusive. The director may take any, all, or
any combination of these actions against a noncompliant user. The
director is empowered to take more than one enforcement action against
any noncompliant user. These actions may be taken concurrently.
(Ordinance 2010-002, sec. XI, adopted 2/16/10)
(a)
Performance bonds.
The director may decline to issue
or reissue a wastewater discharge permit to any user who has failed
to comply with any provision of this division, a previous wastewater
discharge permit, or order issued hereunder, or any other pretreatment
standard or requirement unless such user first files a satisfactory
bond, payable to the city, in a sum not to exceed a value determined
by the director to be necessary to achieve consistent compliance.
(b)
Water supply severance.
Whenever a user has violated
or continues to violate any provision of this division, a wastewater
discharge permit, or order issued hereunder, or any other pretreatment
standard or requirement, water service to the user may be severed.
Service will only recommence, at the user’s expense, after it
has satisfactorily demonstrated its ability to comply.
(c)
Public nuisances.
A violation of any provision of this
division, a wastewater discharge permit, or order issued hereunder,
or any other pretreatment standard or requirement, is hereby declared
a public nuisance and shall be corrected or abated as directed by
the director. Any person(s) creating a public nuisance shall be subject
to the provisions of the city codes/ordinances governing such nuisances,
including reimbursing the city for any costs incurred in removing,
abating, or remedying said nuisance.
(Ordinance 2010-002, sec. XII, adopted 2/16/10)
(a)
Bypass.
(1)
For the purposes of this section:
(A)
“Bypass” means the intentional diversion of wastestreams
from any portion of a user’s treatment facility.
(B)
“Severe property damage” means substantial physical damage
to property, damage to the treatment facilities which causes them
to become inoperable, or substantial and permanent loss of natural
resources which can reasonably be expected to occur in the absence
of a bypass. Severe property damage does not mean economic loss caused
by delays in production.
(3)
(A)
If a user knows in advance of the need for a bypass, it shall submit
prior notice to the director, at least ten (10) days before the date
of bypass, if possible.
(B)
A user shall submit oral notice to the director of an unanticipated
bypass that exceeds applicable pretreatment standards within twenty-four
(24) hours from the time it becomes aware of the bypass. A written
submission shall also be provided within five (5) days of the time
the user becomes aware of the bypass. The written submission shall
contain a description of the bypass and its cause; the duration of
the bypass, including exact dates and times, and, if the bypass has
not been corrected, the anticipated time it is expected to continue;
and steps taken or planned to reduce, eliminate, and prevent reoccurrence
of the bypass. The director may waive the written report on a case-by-case
basis if the oral report has been received within twenty-four (24)
hours.
(4)
(A)
Bypass is prohibited, and the director may take enforcement action
against a user for a bypass, unless:
(i)
Bypass was unavoidable to prevent loss of life, personal injury,
or severe property damage;
(ii)
There were no feasible alternatives to the bypass, such as the
use of auxiliary treatment facilities, retention of untreated wastes,
or maintenance during normal periods of equipment downtime. This condition
is not satisfied if adequate back-up equipment should have been installed
in the exercise of reasonable engineering judgment to prevent a bypass
which occurred during normal periods of equipment downtime or preventative
maintenance; and
(b)
Prohibited discharge standards.
A user shall have an affirmative defense to an enforcement action brought against it for noncompliance with the general prohibitions in section 12.03.035(a)(1) of this division, or the specific prohibitions in section 12.03.035(a)(2)(C) through (G) and 12.03.035(a)(2)(I) through (O) of this division if it can prove that it did not know, or have reason to know, that its discharge, alone or in conjunction with discharges from other sources, would cause pass-through or interference, and that either:
(1)
A local limit exists for each pollutant discharged and the user was
in compliance with each limit directly prior to, and during, the pass-through
[or] interference; or
(2)
No local limit exists, but the discharge did not change substantially
in nature or constituents from the user’s prior discharge when
the city was regularly in compliance with its NPDES permit, and in
the case of interference, was in compliance with applicable sludge
use or disposal requirements.
(c)
Upset provision.
An upset shall constitute an affirmative
defense to an action brought for noncompliance with categorical pretreatment
standards if the requirements of subsection (1) are met.
(1)
An industrial user who wishes to establish the affirmative defense
of upset shall demonstrate, through properly signed, contemporaneous
operation logs, or other relevant evidence that:
(A)
An upset occurred and the industrial user can identify the cause(s)
of the upset;
(B)
The facility was at the time being operated in a prudent and workmanlike
manner and in compliance with applicable operation and maintenance
procedures; and
(C)
The industrial user has submitted the following information to the
POTW and control authority within twenty-four (24) hours of becoming
aware of the upset (if this information is provided orally, a written
submission must be provided within five (5) working days):
(i)
A description of the indirect discharge and cause of noncompliance;
(ii)
The period of noncompliance, including exact dates and times
or, if not corrected, the anticipated time the noncompliance is expected
to continue; and
(iii)
Steps being taken and/or planned to reduce, eliminate and prevent
recurrence of the noncompliance.
(2)
In any enforcement proceeding the industrial user seeking to establish
the occurrence of an upset shall have the burden of proof.
(3)
In the usual exercise of prosecutorial discretion, agency enforcement
personnel should review any claims that noncompliance was caused by
an upset. No determinations made in the course of the review constitute
final agency action subject to judicial review. Industrial users will
have the opportunity for a judicial determination on any claim of
upset only in an enforcement action brought for noncompliance with
categorical pretreatment standards.
(4)
The industrial user shall control production or all discharges to
the extent necessary to maintain compliance with categorical pretreatment
standards upon reduction, loss, or failure of its treatment facility
until the facility is restored or an alternative method of treatment
is provided. This requirement applies in the situation where, among
other things, the primary source of power of the treatment facility
is reduced, lost, or fails.
(Ordinance 2010-002, sec. XIII,
adopted 2/16/10)
(a)
Other sections of the city’s codes/ordinances dealing with
cross-connections, items pertaining to safeguarding the water supply,
waste traps, and items safeguarding the sanitary system remain applicable.
(b)
Compliance with this division does not exempt or excuse a person
from complying with provisions of the Texas Water Quality Act and
its amendments, the Clean Water Act and its amendments, or the requirements
of any applicable waste discharge permit, order, rule or regulation
issued by the state commission on environmental quality (TCEQ) and/or
the Environmental Protection Agency.
(c)
No section or clause in this division shall exclude any agreement
between the director and any person to discharge wastewater, which
complies with the objectives of this division, for treatment by the
city. Said agreements shall provide for reimbursement to the city
for any expense incurred in the treatment and disposal of such wastewater.
(Ordinance 2010-002, sec. XIV, adopted 2/16/10)
(a)
Pretreatment charges and fees.
The city may adopt reasonable
fees for reimbursement of costs of setting up and operating the city’s
pretreatment program, which may include:
(1)
Fees for wastewater discharge permit applications including the cost
of processing such applications;
(2)
Fees for monitoring, inspection, and surveillance procedures, including
the cost of collecting and analyzing a user’s discharge, and
reviewing monitoring reports submitted by users;
(3)
Fees for reviewing and responding to accidental discharge procedures
and construction;
(4)
Fees for filing appeals; and
(5)
Other fees as the city may deem necessary to carry out the requirements
contained herein. These fees relate solely to the matters covered
by this division and are separate from all other fees, fines, and
penalties chargeable by the city.
(b)
Abnormal waste discharge requirements.
Persons generating
abnormal industrial waste may discharge the waste into the sanitary
sewer provided:
(1)
The waste will not cause interference;
(2)
The waste will not endanger or be harmful to the operating personnel
of the sewer system;
(3)
The waste will not cause damage to the collection system;
(4)
The waste will not impair the treatment process;
(5)
The waste will not affect sludge quality and/or require modifications
in sludge disposal practices;
(6)
The waste will not have an effect on receiving water quality;
(7)
The discharge is in compliance with all limitations and requirements in section 12.03.035 of this division;
(8)
The waste shall be assessed a surcharge for any abnormal levels of
BOD or TOC, TSS and FOG or TPH. There shall be one surcharge rate
for BOD or TOC and FOG or TPH and a separate rate for TSS; and
(9)
All required permits are in force and approval in writing has been
given by the director for any waivers or special agreements.
(c)
Computation of surcharges.
(1)
Computation of the surcharge for abnormal industrial waste shall
be based on the following formulas:
|
S = V (8.34) [X(BOD or TOC-200) + Y(TSS-200) + Z(FOG-100) +
Z(TPH-20)]
