maintenance and improvement of the municipal wastewater system;
(5) Protect the health and safety of wastewater treatment and wastewater collection
personnel as well as the general public;
(6) Enable the municipal wastewater system to comply with Texas Pollutant Discharge
Elimination System permit conditions, sludge use and disposal requirements, and
any other federal or state laws; and
(7) To reduce the operational and maintenance costs of maintaining the sewer system
by preventing the accumulation of grease, oil, and residue within the sewage
system lines; and
(8) To ensure the quality of sludge to allow its use and disposal in compliance with all
applicable statutes and requirements.
(b) This ordinance provides for the regulation of direct and indirect contributors to the
municipal wastewater system through the issuance of permits to certain nondomestic

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.
Sec. 106-615. - Public nuisances.
A violation of any section of this ordinance or a provision of a wastewater discharge
permit or order issued under this ordinance or any other pretreatment standard or
requirement is declared a public nuisance and shall be corrected or abated as directed
by the Control Authority. Any person creating a public nuisance shall be subject to the
sections of this Code governing such nuisances, including reimbursing the city for any
costs incurred in removing, abating, or remedying the nuisance.
Secs. 106-616-106-625. - Reserved.
Subdivision III. - Administrative Enforcement
Sec. 106-626. - Authority of Control Authority.
The Control Authority may issue orders without notice or opportunity for prior hearing,
requiring compliance with standards developed under the authority of the act under 40
CFR 403.8(f)(1)(iii).
Sec. 106-627. - Notification of violation.
When the Control Authority finds that a user has violated or continues to violate any
section of this ordinance, a wastewater discharge permit or order issued under this
ordinance or any other pretreatment standard or requirement, the Control Authority may
serve upon that user a written notice of violation. Within 14 days of the receipt date of this
notice, an explanation of the violation and a plan for the satisfactory correction and
prevention thereof, to include specific required actions, shall be submitted by the user to
the Control Authority. Submission of this 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
subdivision shall limit the authority of the Control Authority to take any action, including
emergency action, without first issuing a notice of violation.
Sec. 106-628. - Consent orders.
The Control Authority is empowered to enter into consent orders, assurances of
voluntary compliance, or other similar documents establishing an agreement with any
user responsible for noncompliance with this ordinance. Such documents will include the
specific action to be taken by the user to correct the noncompliance within a time period
also specified by the document. Such document shall have the same force and effect as
the administrative orders issued pursuant to sections 106-630 and 106-631 and shall be
judicially enforceable.
Sec. 106-629. - Show cause hearing.
The Control Authority may order a user which has violated or continues to violate any
section of this ordinance, a wastewater discharge permit or order issued under this
ordinance or any other pretreatment standard or requirement to appear before the Control
Authority 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 days prior to the hearing. Such notice may be served on any
authorized representative of the user. A show of cause hearing shall not be a bar against
or prerequisite for taking any other action against the user. Whether or not a duly notified
user appears as noticed, immediate enforcement action may be pursued. Since the user
will have already been in SNC to necessitate the show cause hearing, any action taken
as a result of the hearing shall be in addition to any penalties levied for the SNC.
Sec. 106-630. - Compliance orders.
When the Control Authority finds that a user has violated or continues to violate any
section of this ordinance, a wastewater discharge permit or order issued under this
ordinance or any other pretreatment standard or requirement, the Control Authority may
issue an order to the user responsible for the discharge directing that the user come into
compliance within a specified time. If the user does not come into compliance within the
time provided, sewer and/or water 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 the installation of pretreatment technology, 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 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.
Sec. 106-631. - Cease and desist orders.
(a) When the Control Authority finds that a user has violated or continues to violate any
section of this ordinance, a wastewater discharge permit or order issued under this
ordinance or any other pretreatment standard or requirement or that the user's past
violations are likely to recur, the Control Authority 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 preventative action as may be needed to
properly address a continuing or threatened violation, including halting operations
and/or terminating the discharge.
(b) Issuance of a cease and desist order shall not be a bar against or a prerequisite for
taking any other action against the user.
Sec. 106-632. - Administrative fines.
(a) When the Control Authority finds that a user has violated or continues to violate any
section of this ordinance, a wastewater discharge permit or order issued under this
ordinance or any other pretreatment standard or requirement, the Control Authority
may fine such a user in an amount not to exceed $2,000.00. Such fine shall be
assessed on a per-violation, per-day basis. For monthly or other long-term average
discharge limits, fines shall be assessed for each day during the period of violation.
Such assessments may be added to the user's next scheduled sewer service charge,
and the Control Authority shall have such other collection remedies as he has to collect
other service charges.
(b) Unpaid charges, fines, and penalties shall, after 14 calendar days, be assessed an
additional penalty of ten percent of the unpaid balance, and interest shall accrue
thereafter at a rate of one percent per month for every month unpaid up to a maximum
of ten percent per month.
(c) A user desiring to dispute such fine must file a written request for the Control Authority
to reconsider the fine along with full payment of the fine amount within ten days of
being notified of the fine. When the Control Authority believes a request has merit, the
Control Authority may convene a hearing on the matter within 15 days of receiving a
request from the user. If the user's appeal is successful, the payment, together with
any interest accruing thereto, shall be returned to the user. The Control Authority may
add the costs of preparing administrative enforcement actions, such as notices and
orders, to the fine.
(d) Issuance of an administrative fine shall not be a bar against or a prerequisite for taking
any other action against the user.
Sec. 106-633. - Emergency suspensions.
(a) The Control Authority may immediately suspend a user's discharge and/or water
service, after informal notice to the user, 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
Control Authority may also immediately suspend a user's discharge and/or water
service, after notice and opportunity to respond, that threatens to interfere with
operation of the publicly owned treatment works or which presents, or may present,
an endangerment to the environment.
(b) Any user notified of a suspension of its discharge shall immediately stop or eliminate
its contribution. If a user fails to immediately comply voluntarily with the suspension
order, the Control Authority may take such steps as deemed necessary, including
immediate severance of the sewer connection, to prevent or minimize damage to the
publicly owned treatment works, its receiving stream, or endangerment to any
individuals. The Control Authority may allow the user to recommence its discharge
when the user has demonstrated to the satisfaction of the Control Authority that the
period of endangerment has passed, unless the termination proceedings in section
106-634 are initiated against the user.
(c) 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
Control Authority prior to the date of any show cause or termination hearing under
section 106-629 or 106-634.
(d) Nothing in this subdivision shall be interpreted as requiring a hearing prior to any
emergency suspension under this section.
Sec. 106-634. - Termination of discharge.
(a) In addition to section 106-765, 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, sampling or industry categorization verification;
(5) Violation of the pretreatment standards in subdivision II of division 4 of this
ordinance;
(6) Violation of any applicable state or federal law; or
(7) Tampering with sampling equipment, sampling lines, or otherwise interfering with
sampling or samples collected for the purpose of influencing or manipulating
sample test results.
(b) Such user will be notified of the proposed termination of its discharge and be offered
an opportunity to show cause under section 106-629 why the proposed action should
not be taken. Exercise of this option by the Control Authority shall not be a bar to or a
prerequisite for taking any other action against the user.
Sec. 106-635. - Liquidated damages.
(a) Each wastewater discharge use permit issued to an industrial user, and as a condition
of issuing such permit, shall contain the following:
"In the event that the Control Authority determines that any user is in violation of any
provisions of Chapter 106, Ordinance VII of the Code of Ordinances of the City of
Wichita Falls, Texas, its wastewater discharge permit, or orders issued hereunder, or
any other pretreatment standard or requirement, the Control Authority shall notify the
user of such violation and require the user to cure the violation within the time
specified in the notice. The user shall respond in writing to the notice of violation within
10 business days from receipt of such notice, setting forth the steps taken to correct
the violation. The Control Authority may extend the time for such response upon a
showing of just cause by the user. If the Control Authority determines that the user is
continuing the violation, the Control Authority may assess liquidated damages at a
minimum of$1,000.00 per violation, per day."
(b) The user retains the right to seek review by the city council of any damages assessed
under this section and the wastewater discharge permit.
(c) Assessments may be added to the user's next scheduled sewer service charge, and
the Control Authority shall have such other collection remedies as may be available
for other service charges and fees.
(d) Issuance of an assessment under this section shall not be a prerequisite for taking
any other action against the user.

Subdivision IV. - Judicial Enforcement
Sec. 106-661. - Authority.
If any person discharges sewage, industrial wastes, or other wastes into the
wastewater disposal system contrary to this ordinance or any order or permit issued under
this ordinance, the Control Authority, through the city attorney, may commence an action
for appropriate legal and/or equitable relief in the municipal court for the city.
Sec. 106-662. - Injunctive relief.
When the Control Authority finds that a user has violated or continues to violate any
section of this ordinance, a wastewater discharge permit, or order issued under this
ordinance or any other pretreatment standard or requirement, the Control Authority may
petition the courts through the city attorney for the issuance of a temporary, preliminary,
and/or permanent injunction, as appropriate, which restrains or compels the specific
performance of the wastewater discharge permit, order, or other requirement imposed by
this ordinance on activities of the user. The Control Authority may also seek such other
action as is appropriate for legal and/or equitable relief, including a requirement for the
user to conduct environmental remediation. A petition for injunctive relief shall not be a
bar against or a prerequisite of taking any other action against a user. The Control
Authority shall have such remedies to collect these fees as it has to collect other sewer
service charges.
Sec. 106-663. - Civil penalties.
(a) A user who has violated or continues to violate any section of this ordinance, a
wastewater discharge permit, or order issued under this ordinance or any other
pretreatment standard or requirement shall be liable to the city for a maximum civil
penalty of$2,000.00 per violation per day plus actual damages incurred by the publicly
owned treatment works. For a monthly or other long term average discharge limit,
penalties shall accrue for each day during the period of the violation.
(b) The Control Authority 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.
(c) 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.
(d) Filing a suit for civil penalties shall not be a bar against or a prerequisite for taking any
other action against a user.
Sec. 106-664. - Criminal prosecution.
(a) For the purpose of this ordinance, the city shall enact all criminal authorities authorized
under state law.
(b) Any user that willfully or negligently violates any section of this ordinance, any orders
or wastewater discharge permits issued under this ordinance or any other
pretreatment requirement shall, upon conviction, be guilty of a misdemeanor,
punishable by a fine of not more than $2,000.00 per violation, per day as provided in
section 106-632.
(c) Any user that knowingly makes any false statements, representations, or certifications
in any application, record, report, plan, or other documentation filed or required to be
maintained pursuant to this ordinance, the wastewater discharge permit or an order
or who falsifies, tampers with or knowingly renders inaccurate any monitoring device
or method required under this ordinance shall, upon conviction, be punished by a fine
per violation.
(d) The purpose of criminal prosecution is to punish noncompliance through court
proceedings and to deter future noncompliance. The city will enforce compliance with
all ordinances in municipal court and will seek the assistance of the district attorney
and/or the U.S. Attorney's office to enforce state statutes and federal laws.
Sec. 106-665. - Remedies nonexclusive.
The remedies provided for in this ordinance are not exclusive. The Control Authority
may take any, all, or any combination of the actions in this subdivision against a
noncompliant user. Enforcement of pretreatment violations will generally be in
accordance with the city's enforcement response plan. However, the Control Authority
may take other action against any user when the circumstances warrant. Further, the
Control Authority is empowered to take more than one enforcement action against any
noncompliant user.
Secs. 106-666-106-690. - Reserved.
Subdivision V. - Affirmative Defenses to Discharge Violations
Sec. 106-691. - Act of God Affirmation Defense
If a person can establish that an event that would otherwise be a violation of this
ordinance within the Control Authority's jurisdiction or an ordinance adopted or an order
or a permit issued under such an ordinance was caused solely by an act of God, war,
strike, riot, or other catastrophe, the event is not a violation of the ordinance or permit.
Sec. 106-692. - Prohibited discharge standards.
A user shall have an affirmative defense to an enforcement action brought against
him for noncompliance with the general prohibitions in section 106-816 or the specific
prohibitions in section 106-817 if the user can prove that he did not know or have reason
to know that the 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 National Pollutant Discharge Elimination System permit and,
in the case of interference, was in compliance with applicable sludge use or
disposal requirements.
Sec. 106-693. - Bypass.
(a) The following words, terms and phrases, when used in this ordinance, shall have the
meanings ascribed to them in this subsection, except where the context clearly
indicates a different meaning:
Bypass means the intentional diversion of wastestreams from any portion of a user's
treatment facility.
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. The term "severe property damage" does not mean economic loss
caused by delays in production.
(b) A user may allow any bypass to occur which does not cause pretreatment standards
or requirements to be violated, but only if it also is for essential maintenance to ensure
efficient operation. These bypasses are not subject to subsections (c) and (d) of this
section.
(c) Notice of bypass shall be given in accordance with the following:
(1) If a user knows in advance of the need for a bypass, it shall submit prior notice to
the Control Authority, at least ten days before the date of the bypass, if possible.
(2) A user shall submit oral notice to the Control Authority of an unanticipated bypass
that exceeds applicable pretreatment standards within 24 hours from the time it
becomes aware of the bypass. A written submission shall also be provided within
five 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; if the bypass has not been corrected,
the anticipated time it is expected to continue; and the steps taken or planned to
reduce, eliminate, and prevent reoccurrence of the bypass. The Control Authority
may waive the written report on a case-by-case basis if the oral report has been
received within 24 hours.
(d) Enforcement action curtailments shall be as follows:
(1) Bypass is prohibited, and the Control Authority may take an enforcement action
against a user for a bypass, unless:
a. Bypass was unavoidable to prevent loss of life, personal injury, or severe
property damage;
b. 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 backup 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
c. The user submitted notices as required under subsection (c) of this section.
(2) The Control Authority may approve an anticipated bypass, after considering its
adverse effects, if the Control Authority determines that it will meet the three
conditions listed in subsection (d)(1) of this section.

Subdivision VI. - Compliance Monitoring
Sec. 106-721. - Inspection and sampling.
In accordance with 40 CFR 403.8(f)(2)(v), the Control Authority shall randomly
inspect and sample each significant industrial user once a year in order to verify self-
monitoring reports and other user-provided information. This section shall not preclude
the Control Authority from sampling and/or inspecting significant industrial users more
frequently or from sampling or inspecting any nonsignificant industrial user or any other
user.
Sec. 106-722. - Right of entry.
(a) The Control Authority and/or the approval authority shall have the right to enter the
premises of any user, whether or not the user possesses a wastewater discharge
permit, to determine whether the user is complying with all the requirements of this
ordinance and any wastewater discharge permit or order issued under this ordinance.
A user shall allow the Control Authority and/or the approval authority ready access to
all parts of the premises for the purpose of sampling, records examination and
copying, and the performance of any additional duties, including determination and
verification of proper classification of the user as a categorical, noncategorical,
significant, or nonsignificant industrial user.
(b) 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 Control
Authority and/or the approval authority will be permitted to enter without delay for the
purposes of performing specific responsibilities.
(c) The Control Authority 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.
(d) The Control Authority may require the user to install sampling equipment, monitoring
equipment, metering equipment, and/or control manholes 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 his own expense. All devices used to
measure wastewater flow and quality shall be calibrated at appropriate intervals to
ensure their accuracy.
(e) Any temporary or permanent obstruction, whether object, condition, or otherwise, to
safe and easy access to the facility or the facility's control point shall be promptly
removed by the user at the written or verbal request of the Control Authority and shall
not be replaced. The costs of clearing such access shall be borne by the user.
(f) Unreasonable delays in allowing the Control Authority and/or the approval authority
access to the user's premises shall be a violation of this ordinance.
(g) The right of access of the Control Authority and/or the approval authority shall extend
to but not be limited to any premises where there is a discharge source or pretreatment
system located or where records are required to be kept by this ordinance or under
40 CFR 403. To make a comprehensive determination of user's compliance status,
the Control Authority and/or the approval authority shall have access to all areas of
the facility, including but not limited to areas where chemicals and raw materials are
stored. This right shall be considered at least as extensive as the authority provided
under section 308 of the Act.
(h) During the course of any visit, the Control Authority and/or the approval authority may
document any part or process of the facility by written document, still photography,
video, audio, or any other recording method deemed appropriate by the Control
Authority and/or the approval authority. The user may use the procedures in section
106-569 to request that portions of the documentation be considered confidential
information.
(i) The user shall not deny access by the Control Authority and/or the approval authority
to any area of the facility for any reason, including but not limited to proprietary
processes, security clearance, safety concern, or personal privacy. Any necessary
arrangements for access to all areas shall have been made by the user beforehand
so that upon presentation of suitable identification, the Control Authority and/or the
approval authority shall be permitted to enter any area of the facility without
reasonable delay for the purposes of performing specific responsibilities. The failure
of the user to make any such necessary arrangements shall not constitute a valid
reason for the user to deny entrance by the Control Authority and/or the approval
authority to any area of the facility.
Sec. 106-723. - Search warrants.
If the Control Authority and/or the approval authority 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 ordinance 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 ordinance or any permit or order issued under this
ordinance or to protect the overall public health, safety and welfare of the community, the
Control Authority may seek issuance of a search warrant.

Subdivision I. - In General
Secs. 106-791-106-815. - Reserved.
Subdivision II. - Prohibited Discharges
Sec. 106-816. - General prohibitions.
No user shall introduce or cause to be introduced into the publicly owned treatment
works any pollutant or wastewater which causes pass through or interference. These
general prohibitions and the specific prohibitions in section 106-817 apply to all users of
the publicly owned treatment works, whether or not they are subject to categorical
pretreatment standards or any other national, state, or local pretreatment standards or
requirements.
Sec. 106-817. - Specific prohibitions.
(a) No user shall introduce or cause to be introduced into the publicly owned treatment
works the following pollutants, substances, or wastewater:
(1) Pollutants which create a fire or explosive hazard in the publicly owned treatment
works, including but not limited to wastestreams with a closed-cup flashpoint of
less than 140 degrees Fahrenheit (60 degrees Celsius) using the test methods
specified in 40 CFR 261.21.
(2) Wastewater having a pH less than five or more than 12, or otherwise causing
corrosive structural damage to the publicly owned treatment works or equipment.
(3) Solid or viscous substances in an amount which will cause obstruction of the flow
in the publicly owned treatment works resulting in interference, but in no case
solids greater than two inches or five centimeters in any dimension.
(4) Pollutants, including oxygen-demanding pollutants (BOD, etc.), released in a
discharge at a flow rate and/or pollutant concentration which, either singly or by
interaction with other pollutants, will cause interference with the publicly owned
treatment works.
(5) Heat in amounts which will inhibit biological activity in the treatment plant resulting
in interference, but in no case heat in such quantities which causes the
temperature at the introduction into the treatment plant to exceed 104 degrees
Fahrenheit (40 degrees Celsius).
(6) Petroleum oil, nonbiodegradable cutting oil, or products of mineral oil origin, in
amounts that will cause interference or pass through.
(7) Pollutants which result in the presence of toxic gases, vapors, or fumes within the
publicly owned treatment works in a quantity that may cause acute worker health
and safety problems.
(8) Trucked or hauled pollutants, except at discharge points designated by the city in
accordance with section 106-854.
(9) Fats, oils and grease in concentrations greater than 500 mg/I, or which violate any
other section of this subdivision.
(b) Pollutants, substances, or wastewater prohibited by this section shall not be
processed or stored in such a manner that they could be discharged to the publicly
owned treatment works.
Sec. 106-818. - National categorical pretreatment standards.
(a) The categorical pretreatment standards found at 40 CFR chapter I, subchapter N,
parts 405-471 are incorporated. All existing or new users shall also comply with all
applicable pretreatment standards and requirements, including those set forth in 40
CFR 403.6.
(b) When wastewater subject to a categorical pretreatment standard is mixed with
wastewater not regulated by the same standard, the Control Authority shall impose an
alternate limit using the combined wastestream formula in 40 CFR 403.6(e).
(c) A user may obtain a variance from a categorical pretreatment standard if the user can
prove, pursuant to the procedural and substantive provisions in 40 CFR 403.13, that
factors relating to its discharge are fundamentally different from the factors considered
by the Environmental Protection Agency when developing the categorical
pretreatment standard.
(d) A user may obtain a net gross adjustment to a categorical standard in accordance
with 40 CFR 403.15.
(1) Categorical Pretreatment Standards may be adjusted to reflect the presence of
pollutants in the Industrial User's intake water in accordance with this section. Any
Industrial User wishing to obtain credit for intake pollutants must make application
to the Control Authority. Upon request of the Industrial User, the applicable
Standard will be calculated on a "net" basis (i.e., adjusted to reflect credit for
pollutants in the intake water) if the requirements of paragraph (2) of this section
are met.
(2) Criteria
(i) Either (i) The applicable categorical Pretreatment Standards contained in
40 CFR subchapter N specifically provide that they shall be applied on a net
basis; or (ii) The Industrial User demonstrates that the control system it
proposes or uses to meet applicable categorical Pretreatment Standards
would, if properly installed and operated, meet the Standards in the absence
of pollutants in the intake waters.
(ii) Credit for generic pollutants such as biochemical oxygen demand (BOD),
total suspended solids (TSS), and oil and grease should not be granted
unless the Industrial User demonstrates that the constituents of the generic
measure in the User's effluent are substantially similar to the constituents
of the generic measure in the intake water or unless appropriate additional
limits are placed on the process water pollutants either at the outfall or
elsewhere.
(iii) Credit shall be granted only to the extent necessary to meet the applicable
categorical Pretreatment Standards(s), up to a maximum value equal to the
influent value. Additional monitoring may be necessary to determine
eligibility for credits and compliance with Standard(s) adjusted under this
section.
(iv) Credit shall be granted only if the User demonstrates that the intake water
is drawn from the same body of water as that into which the POTW
discharges. The Control Authority may waive this requirement if it finds that
no environmental degradation will result.
Sec. 106-819. - State pretreatment standards.
State requirements and limitations on discharges to the publicly owned treatment
works shall be met by all dischargers which are subject to such standards in any instance
in which they are more stringent than federal requirements and limitations or those in this
ordinance or any other applicable ordinance.
Sec. 106-820. - Local limits.
(a) The city has two publicly owned treatment works: POTW#1, known as the Northside
Treatment Plant, located at 5645 Burkburnett Road, Wichita Falls, Texas, and POTW
#2, known as the Wichita Falls Resource Recovery Facility, located at 1005 River
Road, Wichita Falls, Texas. As these two publicly owned treatment works have
different capacities, flow characteristics, and receiving waters, the city has developed
maximum allowable discharge limits for industrial users for each treatment works.
(b) Each industrial discharger will be required to adhere to those limits established at the
treatment works receiving its wastewater discharge. The following local limits are
established to protect against pass through and interference and to protect sludge
quality. These limits are deemed Pretreatment Standards for the purpose of section
307(d) of the Act. Except as provided, no person shall discharge wastewater in excess
of the following maximum allowable discharge limits:
Wichita Falls Northside Treatment
Pollutant Resource Recovery Facility Plant
mg/I mg/I
Antimony 1.42 0.34
Arsenic 0.89 0.21
Beryllium 0.07 0.47
Cadmium 0.39 0.08
Chromium 6.82 3.48
Copper 6.75 2.30
Cyanide 0.38 0.06
Lead 2.26 0.58
Mercury 0.0083 0.0073
Nickel 1 4.64 1 0.34
Phenols 3.94 0.87
Selenium 0.17 0.02
Silver 0.66 0.66
Zinc 42.54 1.72
(c) Discharge of wastewater containing BOD and/or TSS in concentrations greater than
300 mg/I and fats, oils and grease in concentrations greater than 100 mg/I will be
subject to a sewer surcharge at a rate set by the city council to defray the additional
costs of treatment for excessive BOD, TSS and fats, oils and grease at the publicly
owned treatment works.
(d) The surcharge will be an additional charge to the current monthly industrial sewer
charge. The surcharge will not be retroactive, but will continue until such time
subsequent tests determine that the surcharge requires adjustment.
(e) The limits in this section applies to Local Limits only at the point where the wastewater
is discharged to the publicly owned treatment works. All concentrations for metallic
substances are for total metal unless indicated otherwise. The Control Authority may
impose mass limitations in addition to the concentration-based limitations in this
section.
(f) The Control Authority may impose additional and/or alternative limits by permit on
specific individual industrial users. These limits shall be technically based on the
allowable loading of the specified pollutant at the appropriate treatment plant. In no
case shall these additional and/or alternative limits be less stringent than the above
limits, or any applicable federal or state statute.
(g) The Control Authority may develop Best Management Practices (BMPs), by ordinance
or in individual wastewater discharge permits, to implement Local Limits and the
requirements of this ordinance.
Sec. 106-821. - 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 publicly owned
treatment works.
Sec. 106-822. - Dilution.
No user shall ever increase the use of process water or in any other 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 Control Authority 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.
Secs. 106-823-106-850. - Reserved.
Subdivision III. - Pretreatment Requirements
Sec. 106-851. - Pretreatment facilities.
Users shall provide necessary wastewater treatment to comply with this ordinance
and shall achieve compliance with all applicable categorical pretreatment standards, local
limits, and the prohibitions established by this ordinance in subdivision II of this division
within the time limitations specified by the Environmental Protection Agency, the state, or
the Control Authority, 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 operating procedures shall be submitted to the Control
Authority for review and shall be acceptable to the Control Authority 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 city under this ordinance.
Sec. 106-852. - Additional pretreatment measures.
(a) Whenever deemed necessary, the Control Authority 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 meet such other conditions
as may be necessary to protect the publicly owned treatment works and determine
the user's compliance with the requirements of this ordinance.
(b) The Control Authority may require any person discharging into the publicly owned
treatment works to install and maintain, on his property and at his expense, a suitable
storage and flow-control facility to ensure equalization of flow. A wastewater discharge
permit may be issued solely for flow equalization. All records, charts, recorded charts
or strips, and logs of such controls shall be maintained and provided upon request of
the Control Authority.
(c) Grease, oil, and sand interceptors or traps shall be provided when, in the opinion of
the Control Authority, they are necessary for the proper handling of wastewater
containing excessive amounts of grease and oil or sand; however, such interceptors
or traps shall not be required for residential users. All interception units shall be of a
type and capacity approved by the Control Authority and shall be so located to be
easily accessible for cleaning and inspection. Such interceptors or traps shall be
inspected, cleaned, and repaired regularly, as needed, by the user at his expense. A
record of maintenance, repairs, and a log of pumping and waste hauling of contents
shall be maintained and provided to the Control Authority upon request.
(d) Users with the potential to discharge flammable substances may be required to install
and maintain an approved combustible gas detection meter.
(e) The Control Authority may require any user to install or have installed at the user's
expense a control manhole, of a size and construction approvable by the Control
Authority. Additionally, the Control Authority may require the user to construct or have
constructed at the user's expense any structures, appurtenances, fences,
embankments, rail guards, posts, security system, or any other device with eye bolts,
locks, lights, signs, or any other device to ensure the security and safety of Control
Authority personnel and sampling equipment.
Sec. 106-853. - Accidental discharge and slug control plans.
(a) Within one year of being designated as a SIU and at least once every two years
thereafter whether each SIU needs a plan or other action to control slug discharges.
The Control Authority may require any user to develop, submit for approval, and
implement such a plan or take such other action that may be necessary. Alternatively,
the Control Authority may develop such a plan for any user. An accidental discharge
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 Control Authority, other regulatory
agencies such as the EPA and the approval authority, and the appropriate
wastewater treatment plant of any accidental or slug discharge, as required by
section 106-886; 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. The location of floor
drains, if present, and any other possible sources of introduction into the waste
stream or sanitary sewage system will also be identified.
(b) The Control Authority is required to keep records of the activities associated with slug
control evaluations and the results are required to be available to the Approval
Authority upon request.
Sec. 106-854. - Hauled wastewater.
The following requirements are in addition to section 106-311 and subdivision III of
division 2 of this ordinance:
(1) Septic tank waste shall only be introduced into the publicly owned treatment works
at locations designated by the publicly owned treatment works and at such times
as are established by the publicly owned treatment works. Such waste shall not
violate subdivision II of this division or any other requirements established by the
city. The Control Authority shall require septic tank waste haulers to obtain
wastewater discharge permits.
(2) The Control Authority may require haulers of industrial wastewater to obtain
wastewater discharge permits. The Control Authority may require generators of
hauled industrial wastewater to obtain wastewater discharge permits. The Control
Authority may also prohibit the disposal of hauled industrial wastewater. The
discharge of hauled industrial wastewater is subject to all other requirements of
this ordinance.
(3) Industrial wastewater haulers shall discharge loads only at locations designated
by the publicly owned treatment works. No load may be discharged without prior
consent of the publicly owned treatment works. The publicly owned treatment
works or the Control Authority may collect samples of each hauled load to ensure
compliance with applicable standards. The publicly owned treatment works or the
Control Authority may require the industrial wastewater hauler to provide a waste
analysis of any load prior to discharge.
(4) Industrial wastewater hauler must provide a trip ticket for every load.
(5) The superintendent of the POTW, or his designated representative, may at any
time and without prior notice, refuse to allow the discharge of any specific load of
hauled wastewater from any particular liquid waste hauler. This refusal may be
based upon such criteria as questionable physical characteristics of the hauled
wastewater (odor, color, etc.), past history of the manifested liquid waste
generator, or any other such information or judgment that the discharge may
adversely affect the POTW in any way. In the event of such refusal of discharge,
the wastehauler shall provide to the Control Authority within 30 days, a manifest
indicating the proper disposal of that load of hauled wastewater.
Sec. 106-855. - Disposal of contaminated water from leaking petroleum storage
tank sites.
(a) After treatment to specified standards, the contaminated water will be placed in a
sanitary sewer line where possible. Disposal into the sanitary sewer system will be
based on the quality of the water, the peak flow to be placed into the sewer, sewer
capacity available, and the availability of sanitary sewer systems.
(b) If necessary, the treated water can be placed into the storm drainage system. This
disposal method will require an approval authority permit to discharge the treated
water into the surface waters of the state. Disposal via the storm drain system must
not create a nuisance to the properties between the affected site and the public stream
where discharge is permitted by the approval authority.
(c) Where it is not possible or feasible to dispose of the treated waters in the sanitary
sewer or the disposal by storm drain will create a nuisance effect, and no other
disposal methods are available, the city will determine the improvements required in
the sanitary or storm drain systems to accept the flow. All improvements will be at the
sole expense of the owner of the contaminated site. All improvements must be
installed per city standards and procedures, and must be dedicated to the city.
(d) All waters from a contaminated site, before disposal into a sanitary sewer, must meet
the quality standards of this subdivision with the addition of the following standards for
BTEX, lead, and total hydro-carbons:
Chemical ug/liter mg/liter
Benzene 1,000 1.0
Toluene 1,000 1.0
Ethyl benzene 1,000 1.0
Xylenes 1,000 1.0
Total BTEX 2,000 2.0
Total petroleum
Hydrocarbons (TPH) 2.0
Lead (Wichita Falls Resource Recovery Facility POTW) 2.26
Lead (Northside POTW) 1 0.58
1
(e) Prior to disposal of the treated water from the contaminated site, the site owner must
present to the Control Authority a copy of the approval authority approved plan for
corrective action and, as required, an approval authority permit to discharge to surface
waters. The Control Authority will be provided a copy of all laboratory tests conducted
to meet the approval authority requirements in the plan for corrective action. The
Control Authority may require additional tests beyond those of the approval authority
approved plan of corrective action.
(f) These procedures apply to either pump-and-treat flows or batch releases of treated
waters from contaminated sites. Under no circumstances will a site owner dispose of
treated waters from a LPST contaminated site in the city until authorized to do so by
the Control Authority.
(g) The owner will be required to obtain a permit from the Control Authority. This permit
must be renewed annually. The owner must pay an initial permit fee and an annual
fee to renew the permit. In addition, each month the owner may pay a fee to defray
the cost of reviewing lab results and the results of city-initiated sampling and testing
to ensure compliance with both the remedial action plan and the industrial
pretreatment ordinance. These costs must be paid until the site is closed by the
approval authority and disposal of treated waters has ceased. A statement of the
amount of these fees can be obtained from the Control Authority.
(h) If the treated water is disposed of in the sanitary sewer, there will be a minimum
monthly charge plus the current commodity charge per 1,000 gallons disposed. The
amount disposed generally shall be determined by the rated capacity of the pumps in
a pump-and-treat system or by the size of the container in a batch disposal system
(added).
Sec. 106-856. - Fraud and false statements.
The reports and other documents required to be submitted or maintained under this
ordinance shall be subject to:
(1) The provisions of 18 USC 1001 relating to fraud and false statements;
(2) The provisions of section 309(c)(4) of the act, as amended, governing false
statements, representations, or certifications; and
(3) The provisions of section 309(c)(6) of the act regarding responsible corporate
officers.

a. Where the industrial user's categorical pretreatment standard has been
modified by a removal allowance (40 CFR 403.7), the combined wastestream
formula (40 CFR 403.6(e)), and/or a fundamentally different factors variance
(40 CFR 403.13) at the time the user submits the report required by subsection
(b) of this section, the information required by subsections (b)(6) and (7) of this
section shall pertain to the modified limits.
b. If the categorical pretreatment standard is modified by a removal allowance (40
CFR 403.7), the combined wastestream formula (40 CFR 403.6(e)), and/or a
fundamentally different factors variance (40 CFR 403.13) after the user submits
the report required by subsection (b) of this section, any necessary
amendments to the information required by subsections (b)(6) and (7) of this
section shall be submitted by the user to the Control Authority within 60 days
after the modified limit is approved.
c. The Control Authority shall have the authority to set compliance schedules
where and when it so deems necessary or if the user's compliance schedule is
deemed inadequate by the Control Authority.
(8) Signature and certification. All baseline monitoring reports must be signed and
certified in accordance with section 106-758.

Standard necessary to determine the compliance status of the user
Sec. 106-882. - Compliance schedule progress reports.
The following conditions shall apply to the compliance schedule required by section
106-881(b)(7):
(1) The schedule shall contain increments of progress in the form of dates for the
commencement and completion of major events leading to the construction and
operation of additional pretreatment required for the industrial user to meet the
applicable categorical pretreatment standards. Such events include but are not
limited to hiring an engineer, completing preliminary plans, completing final plans,
executing a contract for major components, commencing construction, completing
construction, pretreatment system start-up, first discharge, and beginning and
conducting routine operation.
(2) No increment referred to in subsection (1)of this section shall exceed nine months.
(3) Not later than 14 days following each date in the schedule and the final date for
compliance, the industrial user shall submit a progress report to the Control
Authority, including, at a minimum, whether or not the user complied with the
increment of progress to be met on such date and, if not, the date on which the
user expects to comply with this increment of progress, the reason for delay, and
the steps being taken by the industrial user to return the construction to the
schedule established.
(4) In no event shall more than nine months elapse between such progress reports to
the Control Authority.
Sec. 106-883. - Reports on compliance with categorical pretreatment standard
deadline.
Within 90 days following the date for final compliance with applicable categorical
pretreatment standards or, for a new source, following commencement of the introduction
of wastewater into the publicly owned treatment works, any industrial user subject to such
pretreatment standards and requirements shall submit to the Control Authority a report
containing the information described in section 106-881(b)(4)-(6) & (9). For all other
industrial users subject to categorical pretreatment standards expressed in terms of
allowable pollutant discharge per unit of production or other measure of operation, this
report shall include the user's actual production during the appropriate sampling period.
All compliance reports must be signed and certified in accordance with section 106-758.
All sampling will be done in conformance with section 106-891.
In cases where the Standard requires compliance with a BMP or pollution
prevention alternative, the user shall submit documentation as required by the Control
Authority or the applicable standards to determine compliance with the standard.
Sec. 106-884. - Periodic compliance reports for categorical industrial users.
(a) Any industrial user subject to a categorical standard, after the compliance date of such
pretreatment standard or, for a new source, after commencement of the discharge
into the publicly owned treatment works, shall submit to the Control Authority on or
before July 30th and January 30th, unless required more frequently in the pretreatment
standard or by the Control Authority, the Environmental Protection Agency, or the
approval authority, a report indicating the nature and concentration of pollutants in the
effluent which are limited by such categorical pretreatment standards. In cases where
the pretreatment standard requires compliance with a Best Management Practice
(BMP) or pollution prevention alternative, the industrial user must submit
documentation required by Control Authority or the pretreatment standard necessary
to determine the compliance status of the industrial user. In addition, this report shall
include a record of measured or estimated average and maximum daily flows for the
reporting period for the discharge reported in section 106-881(b)(4) except that the
Control Authority may require more detailed reporting of flows. At the discretion of the
Control Authority and in consideration of such factors as local high or low flow rates,
holidays, budget cycles, etc., the Control Authority may agree to alter the months
during which such reports are to be submitted. All compliance reports must be signed
and certified in accordance with section 106-758. The samplings may be done in the
five months preceding the submittal months; however, they must be done within the
same permit year.
(b) 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.
(c) If a user subject to the reporting requirement in this division monitors any regulated
pollutant at the appropriate sampling location more frequently than required by the
Control Authority, using the procedures prescribed in section 106-891, the results of
this monitoring shall be included in this report.
(d) The reports required in this section shall be based upon data obtained through
appropriate sampling and analysis performed during the period covered by the report,
which data is representative of conditions occurring during the reporting period. The
Control Authority shall require that frequency of monitoring necessary to assess and
ensure compliance by industrial users with applicable pretreatment standards and
requirements.
(e) All periodic compliance reports must be signed and certified in accordance with
section 106-758.
Sec. 106-885. - Periodic compliance reports for significant noncategorical industrial
users.
Significant noncategorical industrial users shall submit to the Control Authority at least
once every six months, on dates specified by the Control Authority, a description of the
nature, concentration, and flow of the pollutants required to be reported to the Control
Authority. In cases where compliance with a Best Management Practice (BMP) or
pollution prevention alternative is required, the user must submit documentation required
by the Control Authority necessary to determine the compliance status of the user. These
reports shall be based on sampling and analysis performed in the period covered by the
report, and performed in accordance with the techniques described in section 106-891.
All periodic compliance reports must be signed and certified in accordance with section
106-758.
Sec. 106-886. - Reports of changed conditions.
(a) Each user must promptly notify both the Control Authority and the POTW in advance
of any planned significant or substantial changes to the user's operations or system
which might alter the nature, character, quality, or volume of its wastewater at least
30 days before the change.
(b) The Control Authority 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 106-759.
(c) The Control Authority may issue a wastewater discharge permit under section 106-
759 or modify an existing wastewater discharge permit under section 106-763 in
response to changed conditions or anticipated changed conditions.
(d) For purposes of this section, significant changes include but are not limited to flow
increases of 20 percent or greater, the discharge of previously unreported pollution,
or the addition of any process subject to categorical pretreatment standards.
(e) Significant industrial users are required to notify the Control Authority immediately of
any changes at its facility affecting the potential for a slug discharge.
Sec. 106-887. - Reports of potential problems.
(a) If any discharge, including but not limited to accidental discharges, discharges of a
nonroutine episodic nature, a noncustomary batch discharge, or any slug discharge,
that may cause potential problems for the publicly owned treatment works or for a
reportable slug load, the user shall immediately telephone and notify the Control
Authority 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.
(b) Industrial users shall notify the CA, EPA 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.
(c) Within five days following such discharge, the user shall, unless waived by the Control
Authority, submit a detailed written report describing the cause of the discharge and
the measures to be 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 publicly owned treatment works,
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.
(d) Every significant industrial user shall permanently post a notice on the user's bulletin
board or other prominent place advising employees and contractors whom to call if a
discharge described in subsection (a) of this section occurs. Employers shall ensure
that all employees and contractors, who may cause such discharge to occur, are
advised of the emergency notification.
Sec. 106-888. - Reports from other users.
(a) All other users required to obtain a wastewater discharge permit shall provide such
information and reports to the Control Authority as required by the wastewater
discharge permit.
(b) All users not required to obtain a wastewater discharge permit shall provide
appropriate reports to the Control Authority as the Control Authority may require.
Sec. 106-889. - Notice of violation; repeat sampling and reporting.
If sampling performed by an industrial user indicates a violation, the user shall notify
the Control Authority within 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
Control Authority within 30 days after becoming aware of the violation, except the
industrial user is not required to resample if the Control Authority performs sampling at
the industrial user:
(1) At a frequency of at least once a month; or
(2) Between the time when the user performs its initial sampling and the time when
the user receives the results of this sampling.
Sec. 106-890. - Discharge of hazardous waste.
Under this division, all users are prohibited from discharging hazardous waste.
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.
Sec. 106-891. - Sampling and analytical requirements.
(a) All pollutant sampling and analyses 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 136 and amendments thereto, unless otherwise stated in an
applicable categorical pretreatment standard. Where 40 CFR 136 does not contain
sampling or analytical techniques for the pollutant in question or where the
administrator determines that the 40 CFR 136 sampling and analytical techniques are
inappropriate for the pollutant in question, sampling and analysis shall be performed
by using validated analytical methods or any other applicable sampling and analytical
procedures, including procedures suggested by the publicly owned treatment works
or other parties, approved by the administrator.
(b) A minimum of four grab samples must be used for pH, cyanide, total phenols, oil and
grease, sulfide, and volatile organics. For all other pollutants, 24-hour composite
samples must be obtained through flow-proportional composite sampling techniques
where feasible. The Control Authority may waive flow-proportional composite
sampling for any industrial user that demonstrates that flow-proportional sampling is
infeasible. In such cases, samples may be obtained through time-proportional
composite sampling techniques or through a minimum of four grab samples where the
user demonstrates that this will provide a representative sample of the effluent being
discharged.
(1) Any report required by the Control Authority must be based upon data obtained
through appropriate sampling and analysis performed during the period covered
by the report, which data are representative of conditions occurring during the
reporting period. The frequency of monitoring shall be of that frequency necessary
to assess and assure compliance by Industrial Users with applicable Pretreatment
Standards and Requirements. Grab samples must be used for temperature, pH,
cyanide, total phenols, oil and grease, sulfide, and volatile organic compounds.
For all other pollutants, 24-hour composite samples must be obtained through
flow-proportional composite sampling techniques, unless time-proportional
composite sampling or grab sampling is authorized by the Control Authority.
Where time-proportional composite sampling or grab sampling is authorized by
the Control Authority, the samples must be representative of the Discharge and
the decision to allow the alternative sampling must be documented in the Industrial
User file for that facility or facilities. Using protocols (including appropriate
preservation) specified in 40 CFR part 136 and appropriate EPA guidance,
multiple grab samples collected during a 24-hour period may be composited prior
to the analysis as follows: For cyanide, total phenols, and sulfides the samples
may be composited in the laboratory or in the field; for volatile organics and oil &
grease the samples may be composited in the laboratory. Composite samples for
other parameters unaffected by the compositing procedures as documented in
approved EPA methodologies may be authorized by the Control Authority, as
appropriate.
(2) All analyses shall be performed in accordance with procedures established by the
Administrator pursuant to section 304(h) of the Act and contained in 40 CFR Part
136 and amendments thereto or with any other test procedures approved by the
Administrator. (See, §§136.4 and 136.5.) Sampling shall be performed in
accordance with the techniques approved by the Administrator. Where 40 CFR
part 136 does not include sampling or analytical techniques for the pollutants in
question, or where the Administrator determines that the part 136 sampling and
analytical techniques are inappropriate for the pollutant in question, sampling and
analyses shall be performed using validated analytical methods or any other
sampling and analytical procedures, including procedures suggested by the
POTW or other parties, approved by the Administrator.
(3) All analyses shall be performed in accordance with procedures established by the
Administrator pursuant to section 304(h) of the Act and contained in 40 CFR Part
136 and amendments thereto or with any other test procedures approved by the
Administrator. (See, §§136.4 and 136.5.) Sampling shall be performed in
accordance with the techniques approved by the Administrator. Where 40 CFR
part 136 does not include sampling or analytical techniques for the pollutants in
question, or where the Administrator determines that the part 136 sampling and
analytical techniques are inappropriate for the pollutant in question, sampling and
analyses shall be performed using validated analytical methods or any other
sampling and analytical procedures, including procedures suggested by the
POTW or other parties, approved by the Administrator.
(4) if any Categorical Industrial User, any non-categorical Significant Industrial User,
or any other Industrial User subject to reporting requirements monitors any
regulated pollutant at the appropriate sampling location more frequently than
required by the Control Authority, using the procedures prescribed in this section,
the results of this monitoring shall be included in the report.
(5) Non-detectable sampling results may be used only as a demonstration that a
pollutant is not present if the EPA approved method from 40 CFR 136 with the
lowest minimum detection level for that pollutant was used in the analysis.
(c) Submissions of all pollutant analyses shall contain the following:
(1) A copy of the laboratory report should be attached. The report should include the
following information:
a. The name, address, and telephone number of the laboratory performing the
analysis.
b. The units in which each parameter is reported.
c. The method of analysis used (e.g., Environmental Protection Agency 335.1,
3500-Zn-A, etc.). The method must be a technique for wastewater analysis as
prescribed in 40 CFR 136.
d. The detection limit for each parameter measurement.
e. The name, initials, or other such unambiguous identification of the analyzing
technician.
f. The date each analysis was performed.
g. The signature of the laboratory director, or equivalent position.

i. The results of the analyses.
(2) A copy of the chain of custody records should be attached. Each record shall have
the following:
a. The name and address of the user being sampled.
b. The sample container identification number or other such unique, unambiguous
identification.
c. For a grab sample, the date and time the sample was taken.
d. For a composite sampling, the date and time the composite sampler was set
up and the date and time the composite sampler was retrieved.
e. The exact sampling point of the sample.
f. The method of taking the sample (i.e., grab sample, automatic or manual flow-
proportioned composite sample, automatic or manual time-proportioned
composite sample, etc.).
g. The name, title, and signature of the person taking the sample.
h. The method of preservation of the sample and the date and time it was
preserved, or if no preservation was necessary.
i. The date and time dispatched for analysis, the name of the dispatcher, and the
method of shipment, if the sample was so dispatched.
j. The name of the individual, company, and/or address to which the sample is
dispatched.
k. The signature of the receiver of the sample, the date and time of its receipt,
who it was received from, and its disposition.
(d) 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.
