MEMO TO: HONORABLE MAYOR AND MEMBERS OF THE CITY COUNCIL
FROM: ROGER NELSON, CITY MANAGER ,/,
MEETING DATE: FEBRUARY 18, 2003
SUBJECT: AMENDMENT TO INDUSTRIAL WASTEWATER TREATMENT
ORDINANCE
RECOMMENDATION:
City Council to consider amending sections 25-60 through 25-86 of Chapter 25 Utilities
and Services relative to Industrial wastewater treatment of the City of Grapevine Code of
Ordinances.
FUNDING SOURCE:
Not Applicable
BACKGROUND:
The City of Grapevine entered into a contract with the Trinity River Authority of Texas to
provide wastewater treatment service in the early 1980s. The Trinity River Authority
(TRA) is a regional water and wastewater service provider and serves 21 Metroplex
Cities. Grapevine has two wastewater service areas. The north half of Grapevine is
served by the Grapevine Wastewater Treatment Plant and the south half of Grapevine is
served by TRA.
Wastewater treatment facilities operate under the authority of a permit granted by the
United States Environmental Protection Agency and the State of Texas. The permit may
contain a subsection that requires an approved Industrial Pretreatment Ordinance.
Grapevine does not have an Industrial Pretreatment requirement in our operating permit
but TRA is required to implement a program. Grapevine passed a similar ordinance in
1976 but because we are a member of the TRA regional wastewater system, Grapevine
and all twenty-one member cities, must approve the attached Ordinance amendment.
The Industrial Pretreatment Ordinance establishes a mechanism that allows industrial
entities to discharge their wastewater into the wastewater system. The wastewater
treatment plant is able to easily treat normal residential wastewater. Industrial waste
may have a deleterious effect on the wastewater treatment plant's ability to effectively
treat the waste. The objectives of this ordinance are as follows:
February 11, 2003 (5:OOPM)
a • To prevent the introduction of pollutants into the treatment plant that will
interfere with its operation;
• To prevent the introduction of pollutants into the treatment plant that will pass
through the plant, inadequately treated, into the receiving waters, or
otherwise be incompatible with the treatment plant;
• To protect both the treatment works personnel who may be affected by
wastewater and sludge in the course of their employment and the general
public;
• To promote reuse and recycling of industrial wastewater and sludge from the
treatment works;
• To provide for fees for the equitable distribution of the cost of operation,
maintenance and improvement of the treatment works;
• To enable the City to comply with the wastewater discharge permit, sludge
use and disposal requirements, and any other Federal or State laws to which
the treatment works is subject.
This ordinance establishes a process by which an industry can apply for a permit and
discharge industrial waste to the wastewater system.
The industrial wastewater discharged to the City system must meet very specific
numerical limits for pollutants such as heavy metals, pH, temperature, oils and greases,
non -biodegradable products, insecticides and herbicides etc. In the event a company or
industry is classified by the Federal Government as having the potential for this type of
discharge they must get a permit from the City of Grapevine. The ordinance provides for
the permit process and a legal process if the wastewater discharge exceeds these limits.
The industrial user who is required to obtain a permit must report wastewater discharge
characterization to the City and the City may sample the discharge of any industrial user
to ensure compliance with the ordinance. The City reserves the right to terminate
service to the industrial user in the event of a violation of the pretreatment ordinance.
Civil and criminal penalties may be assessed per violation with a fine of not more than
two thousand dollars ($2,000) or imprisonment as decided by an appropriate court.
Currently there is only one industrial facility in Grapevine that is required to get an
industrial discharge permit but all discharges to the wastewater system must comply with
this ordinance.
February 11, 2003 (8:09AM)
The City Attorney has worked closely with Public Works Staff and has approved the
Ordinance Amendment.
Staff recommends approval of the Industrial Wastewater Treatment Amendment.

is amenable to treatment, including but not limited to bulk or packaged chemical products.
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 POTW.
61.2 National Categorical Pretreatment Standards
The categorical pretreatment standards found at 40 CFR Chapter I, Subchapter N, Parts 405-471 are
hereby incorporated.
A. Where a categorical pretreatment standard is expressed only in terms of either the mass or the
concentration of a pollutant in wastewater, the Designated City Official may impose equivalent
concentration or mass limits in accordance with 40 CFR 403.6(c).
B. When wastewater subject to a categorical pretreatment standard is mixed with wastewater not
regulated by the same standard, the Designated City Official 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 EPA 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.
61.3 Requirements for building sewers.
Any person responsible for discharges through a building sewer carrying industrial wastes shall, at his
own expense and as required by the City:
A. Install an accessible and safely located control manhole;
B. Install meters and other appurtenances to facilitate observation sampling and measurement of
the waste; and
-11-
C. Maintain the equipment and facilities.
61.4 Local Limits
The following pollutant limits are established to protect against pass through and interference. No
person shall discharge or cause or permit to be discharged, wastewater containing in excess of the following
instantaneous maximum allowable discharge limits into the following system(s): Trinity River Authority POTW
and the City of Grapevine POTW.
0.2 mg/I arsenic
0.1 mg/I cadmium

65.9 Notification of the Discharge of Hazardous Waste
A. 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 and concentration of such constituents in the wastestream discharged during that
calendar month, and an estimation of the mass of constituents in the wastestream expected to
be discharged during the following twelve (12) months. All notifications must take place no later
than one hundred and eighty (180) days after the discharge commences. Any notification under
this paragraph need be submitted only once for each hazardous waste discharged. However,
notifications of changed conditions must be submitted under Section 65.5 of this ordinance. 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 Sections
65.1, 65.3, and 65.4 of this ordinance.

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 non-acute 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.
-24-
C. 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 Designated City Official, the POTW, 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.
D. 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.
E. This provision does not create a right to discharge any substance not otherwise permitted to be
discharged by this ordinance, a permit issued thereunder, or any applicable Federal or State law.
65.10 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 EPA.
65.11 Sampling and Testing.
A. Sampling shall be conducted according to customarily accepted methods, reflecting the effect of
constituents upon the sewage works and determining the existence of hazards to health, life, limb, and
property.
(NOTE: The particular analyses involved will determine whether a 24 hour composite sample from all outfalls
of a premise is appropriate or whether a grab sample or samples should be taken. Normally, but not always,
BOD and suspended solids analyses are obtained from 24-hour composites of all outfalls. Where applicable,
16 -hour, 8 -hour or some other period may be required. Periodic grab samples are used to determine pH.)
B. Examination and analyses of the characteristics of waters and wastes required by this section shall be:
(1) Conducted in accordance with the latest approved edition of Standard Methods; and
(2) Determined from suitable samples taken at the control manhole provided or other control point
authorized by the approving authority.
C. BOD and suspended solids shall be determined from composite sampling.
-25-
D. The city shall select an independent firm or laboratory to determine flow, BOD, suspended solids and
other chemical analysis as necessary.
E. Except as indicated in Subsection G, below, the user must collect wastewater samples using flow
proportional composite collection techniques, In the event flow proportional sampling is infeasible, the
Designated City Official and/or Control Authorities 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 used to show compliance with
instantaneous discharge limits.
F. Samples for oil and grease, temperature, pH, cyanide, phenols, sulfides, and volatile organic
compounds must be obtained using grab collection techniques.
65.12 Timing
Written reports will be deemed to have been submitted on the date postmarked. For reports which 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.
65.13 Record Keeping
Users subject to the reporting requirements of this ordinance shall retain, and make available for
inspection and copying, all records of information obtained pursuant to any monitoring activities required by
this ordinance 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; and the results of such analyses. These
records shall remain 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 of Grapevine, or where the user has
been specifically notified of a longer retention period by the Designated City Official and/or Control Authorities.

used to measure wastewater flow and quality shall be calibrated, at a minimum, annually to
ensure their accuracy.
D. 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
Designated City Official and/or Control Authorities and shall not be replaced. The costs of
clearing such access shall be born by the user.
E. Unreasonable delays in allowing the inspecting or sampling person access to the user's premises
shall be a violation of this ordinance.
F. in accordance with 40 CFR 403, the City shall inspect and monitor each permitted Industrial User
h a minimum of once per year. If the City elects to perform compliance monitoring for the industry
then the City will monitor the industry a minimum of semi annually.
66.2 Search Warrants
If the Designated City Official and/or Control Authorities 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 Of Grapevine designed to verify compliance with this ordinance or any
permit or order issued hereunder, or to protect the overall public health, safety and welfare of the community,
then the Designated City Official and/or Control Authorities may seek issuance of a search warrant from the
an appropriate court.
SECTION 25 — 67 - CONFIDENTIAL INFORMATION
Information and data on a user obtained from reports, surveys, wastewater discharge permit
applications, wastewater discharge permits, and monitoring programs, and from inspection and sampling
activities, shall be available to the public without restriction, unless the user specifically requests, and is able
-27-
to demonstrate to the satisfaction of the City and/or Control Authority, 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.
SECTION 25 — 68 - PUBLICATION OF USERS IN SIGNIFICANT NONCOMPLIANCE
The Designated City Official shall publish annually, in the largest daily newspaper published in the
municipality where the POTW is located, 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:
A. 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- (6-) month period exceed the
daily maximum limit or average limit for the same pollutant parameter by any amount;
B. 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- (6-)
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);
C. Any other discharge violation that the Designated City Official and/or Control Authorities 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;
D. Any discharge of pollutants that has caused imminent endangerment to the public or to the
environment, or has resulted in the Designated City Official or Control Authorities exercise of its
emergency authority to halt or prevent such a discharge;
E. 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;
F. 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;
G. Failure to accurately report noncompliance; or
-28-
H. Any other violation(s) which the Designated City Official determines will adversely affect the
operation or implementation of the local pretreatment program.
SECTION 25 — 69 - ADMINISTRATIVE ENFORCEMENT REMEDIES
69.1 Notification of Violation
When the Designated City Official finds that a user has violated, or continues to violate, any provision
of this ordinance, a wastewater discharge permit or order issued hereunder, or any other pretreatment
standard or requirement, the Designated City Official may serve upon that user a written Notice of Violation.
Within the time frame specified in the notice, which is usually, but not always 10 days, 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 Designated City Official. 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
section shall limit the authority of the Designated City Official to take any action, including emergency actions
or any other enforcement action, without first issuing a Notice of Violation.
69.2 Reserved
69.3 Show Cause Hearing
The Designated City Official may order a user which has violated, or continues to violate, any provision
of this ordinance, a wastewater discharge permit or order issued hereunder, or any other pretreatment
standard or requirement, to appear before the Designated City official 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.
9a*
69.4 Compliance Orders
When the Designated City Official finds that a user has violated, or continues to violate, any provision
of this ordinance, a wastewater discharge permit or order issued hereunder, or any other pretreatment
standard or requirement, the Designated City Official 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 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 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.
69.5 Cease and Desist Orders
When the Designated City Official finds that a user has violated, or continues to violate, any provision
of this ordinance, 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 Designated City Official may
issue an order to the user directing it to cease and desist all such violations and directing the user to:
A. Immediately comply with all requirements; and
B. 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.
69.6 Reserved
69.7 Emergency Suspensions
The Designated City Official may immediately suspend a user's discharge, 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 Designated City Official may also immediately suspend a user's discharge, after notice and opportunity
-30-
to respond, that threatens to interfere with the operation of the POTW, or which presents, or may present, an
0 endangerment to the environment.
A. 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 Designated City Official or Control Authorities 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 Designated
City official may allow the user to recommence its discharge when the user has demonstrated
to the satisfaction of the Designated City Official that the period of endangerment has passed,
unless the termination proceedings in Section 69.8 of this ordinance are initiated against the user.
B. 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 Designated City
Official prior to the date of any show cause or termination hearing under Sections 69.3 or 69.8
of this ordinance.
Nothing in this section shall be interpreted as requiring a hearing prior to any emergency suspension under
this section.
69.8 Termination of Discharge
In addition to the provisions in Section 64.6 of this ordinance, any user who violates the following
conditions is subject to discharge termination:
A. Violation of wastewater discharge permit conditions;
B. Failure to accurately report the wastewater constituents and characteristics of its discharge;
C. Failure to report significant changes in operations or wastewater volume, constituents, and
characteristics prior to discharge;
D. Refusal of reasonable access to the user's premises for the purpose of inspection, monitoring,
or sampling; or
E. Violation of the pretreatment standards in Section 25 — 61 of this ordinance.
Such user will be notified of the proposed termination of its discharge and be offered an opportunity to
show cause under Section 69.3 of this ordinance why the proposed action should not be taken. Exercise of
this option by the Designated city Official shall not be a bar to, or a prerequisite for, taking any other action
against the user.
-31-
SECTION 25 — 70 - JUDICIAL ENFORCEMENT REMEDIES
70.1 Injunctive Relief
When the Designated City Official finds that a user has violated, or continues to violate, any provision
of this ordinance, a wastewater discharge permit, or order issued hereunder, or any other pretreatment
standard or requirement, the Designated City Official may petition the appropriate Court through the City of
Grapevine'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 ordinance on activities of the user. The Designated City Official 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 for, taking any other
action against a user.
70.2 Civil Penalties
A. A user who has violated, or continues to violate, any provision of this ordinance, a wastewater
discharge permit, or order issued hereunder, or any other pretreatment standard or requirement
shall be liable to The City of Grapevine for a maximum civil penalty of One Thousand Dollars

limit, penalties shall accrue for each day during the period of the violation.
B. The Designated City Official 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 of Grapevine.
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.
E. Failure to pay. In addition to sanctions provided for by this division, the city is entitled to exercise
sanctions provided for by the other ordinances of the city for failure to pay the bill for water and
sanitary sewer service when due.
70.3 Criminal Prosecution
A. A user who violates any provision of this ordinance, 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 Two Thousand Dollars
($2,000.00) per violation, per day, or imprisonment as decided by an appropriate court, or both.
-32-
B. A user who negligently introduces any substance into the POTW which causes personal injury
or property damage shall, upon conviction, be guilty of a misdemeanor and be subject to the
same penalties described in 70.3.A. of this Ordinance. This penalty shall be in addition to any
other cause of action for personal injury or property damage available under State law.
C. A user who 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, wastewater discharge permit, or order issued hereunder, or who falsifies, tampers
with, or renders inaccurate any monitoring device or method required under this ordinance shall,
upon conviction, be subject to the same penalties described in 70.3.A. of this Ordinance.
D. CRIMINAL RESPONSIBILITY. A culpable mental state is not required to prove an offense under
this Ordinance. A person is criminally responsible for a violation of this Ordinance if:
(1) the person commits or assists in the commission of a violation, or causes or permits
another person to commit a violation; or
(2) the person owns or manages the property or facilities determined to be the cause of the
illegal discharge under Section 61.1, 61.2, 61.4, 62.4, or 63.2.
70.4 Remedies Nonexclusive
The remedies provided for in this ordinance are not exclusive. The Designated City Official may take
any, all, or any combination of these actions against a noncompliant user. Enforcement of pretreatment
violations will generally be in accordance with The City of Grapevine's Enforcement Response Plan (ERP).
However, the Designated City Official may take other action against any user when the circumstances
warrant. Further, the Designated City Official is empowered to take more than one enforcement action against
any noncompliant user.
70.5 Applicability of More Stringent Regulations
A. If national pretreatment standards, categorical or otherwise, more stringent than the discharge
limits prescribed in this article are promulgated by the United States Environmental Protection
Agency for certain industries, the more stringent national pretreatment standards will apply to the
affected industrial user. A violation of the more stringent national pretreatment standards will also
be considered a violation of this Ordinance.
B. Applicability of more stringent discharge limits. An industrial user within the city who discharges
industrial waste ultimately received and treated by another governmental entity pursuant to a
wholesale wastewater contract or a reciprocal agreement with the city is subject to the following
additional rules:
-33-
(1) If the governmental entity has more stringent discharge limits than those prescribed by this
Ordinance, or by a discharge permit issued hereunder, because the United States
Environmental Protection Agency requires the more stringent discharge limits as part of the
governmental entity's wastewater pretreatment program, the more stringent discharge limits
shall prevail.
(2) The Designated City Official is authorized to issue a discharge permit to an industrial user
affected by Subsection (1), to insure notice of and compliance with the more stringent
discharge limits. If the industrial user already has a discharge permit, the Designated City
Official may amend the permit to apply and enforce the more stringent discharge limits. An
industrial user shall submit to the Designated City Official an expected compliance date and
an installation schedule if the more stringent discharge limits necessitate technological or
mechanical adjustments to discharge facilities or plant processes.
(3) if the Designated City Official chooses not to issue or amend a permit under Subsection (2),
the Designed City Official shall notify the affected industrial user in writing of the more
stringent discharge limits and their effective date. Regardless of whether or not a permit
is issued or amended, an industrial user shall be given a reasonable opportunity to comply
with the more stringent discharge limits.
(4) The more stringent discharge limits cease to apply upon termination of the city's wholesale
wastewater contract or reciprocal agreement with the governmental entity, or upon
modification or elimination of the limits by the government entity or the United States
Environmental Protection Agency. The Designated City Official shall take the appropriate
action to notify the affected industrial user of an occurrence under this Subsection (4).
C. Variances in compliance dates. The Designated City Official may grant a variance in compliance
dates to an industry when, in Designated City Official's opinion, such action is necessary to
achieve pretreatment or corrective measures. In no case shall the Designated City Official grant
a variance in compliance dates to an industry affected by national categorical pretreatment
standards beyond the compliance dates established by the United States Environmental
Protection Agency.
-34-
u„ D. Authority to regulate. The Designated City Official may establish regulations, not in conflict with
this Ordinance other laws, to control the disposal and discharge of industrial waste into the
wastewater system and to insure compliance with the city's pretreatment enforcement program
with all applicable pretreatment regulations promulgated by the United States Environmental
Protection Agency. The regulations established shall, where applicable, be made part of any
discharge permit issued to an industrial user by the Designated City Official.
SECTION 25 — 71 - RESERVED
SECTION 25 — 72 - AFFIRMATIVE DEFENSES TO DISCHARGE VIOLATIONS
72.1 In an action brought in federal court only:
Upset Provision
A. For the purposes of this section, "upset" means an exceptional incident in which there is
unintentional and temporary noncompliance with categorical pretreatment standards because of
factors beyond the reasonable control of the user. An upset does not include noncompliance to
the extent caused by operational error, improperly designed treatment facilities, inadequate
treatment facilities, lack of preventive maintenance, or careless or improper operation.
B. An upset shall constitute an affirmative defense to an action brought for noncompliance with
categorical pretreatment standards if the requirements of paragraph (C), below, are met.
C. A user who wishes to establish the affirmative defense of upset shall demonstrate, through
properly signed, contemporaneous operating logs, or other relevant evidence that:
(1) An upset occurred and the user can identify the cause(s) of the upset;
(2) The facility was at the time being operated in a prudent and workman -like manner and in
compliance with applicable operation and maintenance procedures; and
(3) The user has submitted the following information to the Designated City official 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) days:
(a) A description of the indirect discharge and cause of noncompliance;
(b) The period of noncompliance, including exact dates and times or, if not corrected, the
anticipated time the noncompliance is expected to continue; and
(c) Steps being taken and/or planned to reduce, eliminate, and prevent recurrence of the
noncompliance.
D. In any enforcement proceeding, the user seeking to establish the occurrence of an upset shall
have the burden of proof.
-35-
E. 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.
F. Users shall control production of 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.
72.2 In an action brought in municipal or state court only:
Act of God Provision
A. An event that would otherwise be a violation that is caused solely by an act of God, war, strike,
riot, or other catastrophe is not a violation.
B. In any enforcement proceeding, the user seeking to establish the occurrence of an act of God,
war, strike, riot, or other catastrophe shall have the burden of proof.
C. In the event that A. and B. above has been demonstrated the user shall control production of all
discharges to the extent necessary to maintain compliance with pretreatment standards upon
reduction, loss, or failure of its treatment facility until the facility is restored or an alternative
method of treatment is provided.
72.3 Bypass
A. For the purposes of this section:
(1) "Bypass" means the intentional diversion of wastestreams from any portion of a user's
treatment facility.
(2) "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.
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 assure efficient
operation. These bypasses are not subject to the provision of paragraphs (C) and (D) of this
section.
C. (1) If a user knows in advance of the need for a bypass, it shall submit prior notice to the
Designated City Official, at least ten (10) days before the date of the bypass, if possible.
(2) A user shall submit oral notice to the Designated City Official 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
-36-
reoccurrence of the bypass. The Designated City Official may waive the written report on
a case-by-case basis if the oral report has been received within twenty-four (24) hours.
D. (1) Bypass is prohibited, and the Designated City Official 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 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 preventive maintenance; and
(c) The user submitted notices as required under paragraph (C) of this section.
(2) The Designated City Official may approve an anticipated bypass, after considering its
adverse effects, if the Designated City Official determines that it will meet the three
conditions listed in paragraph (D)(1) of this section.
SECTION 25 — 73 - WASTEWATER TREATMENT RATES
[RESERVED]
SECTION 25 - 74 - MISCELLANEOUS PROVISIONS
74.1 Pretreatment Charges and Fees
A. The City of Grapevine has adopted reasonable fees for reimbursement of costs of setting up and
operating The City of Grapevine's Pretreatment Program which includes:
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 collection
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 of Grapevine may deem necessary to carry out the requirements
contained herein. These fees relate solely to the matters covered by this ordinance and are
separate from all other fees, fines, and penalties chargeable by City of Grapevine.
6. Fees for treating abnormal strength wastes
7. Fees incurred from an upset, bypass or unauthorized discharge.
-37-
B. Surcharge
The city may surcharge industrial users for the treating of abnormal strength wastes. Water or
wastes having 1) a five day biochemical oxygen demand greater than two hundred fifty (250)
parts per million (ppm) by weight or 2) containing more than two hundred fifty (250) parts per
million by weight of total suspended solids shall be subject to the review and approval of the the
Designated City Official. Where the Designated City Official has approved the admission of (1)
or (2) above into the POTW, that discharge may be subject to a surcharge as determined by the
Designated City Official. In no case shall a discharge be accepted that will prevent the POTW
from meeting its limits.
The surcharge will be assessed according to the following formula each month using the most
current pollutant concentration data and the current months' wastewater flow:
Surcharge = Q x [a(BOD - 250) + b(TSS - 250)][8.34]
1,000
Where:
Q = flow in gallons
8.34 = weight in pounds of one gallon of water
x = normal limits of BOD in domestic wastewater expressed in milligrams per liter
y = normal limits of TSS in domestic wastewater expressed in milligrams per liter
a = 0.05168 or latest unit cost of treatment per pound of BOD.
b = 0.04512 or latest unit cost of treatment per pound of TSS.
BOD = measured amount of BOD, in mg/I
TSS = measured amount of TSS, in mg/I
A surcharge is an additional charge by the POTW for the increased cost of handling discharge
of unusual strength and character and shall not serve as a variance to the requirements of this
ordinance. Exercise of this provision shall not be a bar to, or a prerequisite for, taking any other
action against the user.
74.2 Severability
If any provision of this ordinance is invalidated by any court of competent jurisdiction, the remaining
provisions shall not be effected and shall continue in full force and effect.
SECTION 25 — 75 - EFFECTIVE DATE
This ordinance shall be in full force and effect immediately following its passage, approval, and
publication, as provided by law.
