Objectives of this ordinance are:
a) To provide for the orderly functioning of the PQTW;
b) To provide control of construction and use of the City
sewer system.
c) To prevent the introduction of pollutants into the City
wastewater system which will interfere with the operation of
the system or contaminate the resulting sludge;
d) To prevent the introduction of pollutants into the municipal
wastewater system which will pass through the system,
inadequately treated, into the receiving waters or the
atmosphere or otherwise be incompatible with the system;
e) To improve the opportunity to recycle and reclaim
wastewater and sludges from the system; and
f) To provide for the equitable distribution of the cost of the
municipal wastewater system.
It is the intent of the City of Paris, Paris, Texas, to provide
needed sewer service to all users vUhile meeting the outlined objec-
tives. This ordinance provides the structure under which the service

structed, used or maintained, on or about such property, any privy,
cesspool, water closet, urinal, slop sink, slop drain, bathtub, waste
drain, or any other apparatus for the purpose of receiving or
removing sewage matter or slop of any kind, unless the same is
connected with the sanitary sewer system of the City.
B. CONNECTION TO SEWERS REQUIRED
Every building containing plumbing, any portion of which is
within two hundred (200) feet of an available sewer, shall be
connected with a public sewer within six months after the owner,
leasee, or occupant thereof receives written notice from the Director
of Community Development to do so. For the purposes of this
provision, notice shall begin upon mailing of said notice by certified
or registered mail directed to owner, leasee or occupant.
Upon failure of said owner, leasee or occupant to connect said
premises to a public sewer, the Director of Community Development
shall have the right to make the connection of said premises to the
public sewer and charge the cost thereof, including labor and mate-
rials necessarily used, as well as any other expenses connected
therewith, against such owner, leasee or occupant, who shall be
personally liable for the payment thereof. To secure payment of such
costs, the City of Paris, Paris, Texas shall have a lien against the
property on which the connection was made.
C. WASTEWATER FROM CUSTOMERS OUTSIDE THE CITY LIMITS
The POTW may elect to accept wastewater from sources outside
the City of Paris, Paris, Texas. Acceptance of holding tank wastes
such as, but not limited to, septage may be accepted at the discretion
of the Superintendent after consideration of the POTW's ability to
treat the waste properly and with the approval of the Superintendent
of Public Works, City Engineer and Wastewater Superintendent.
Unless otherwise directed the rate for acceptance will be twice the
cost to treat. This shall in no way prohibit the City of Paris, Paris,
Texas, from making individual contracts between the City of Paris,
Paris, Texas, and an outside user. No outside user shall make any
plumbing connection or pump or pipe wastewater to the POTW without
the specific apprQVal of the City Council of the City of Paris, Paris,
Texas.
D. GENERAL PROHIBITIONS

F. STATE AND FEDERAL LIMITATIONS O1`d DISCHARGES
State and/or federal limitations and requirements on discharges,
which apply to the POTW or its users, shall apply in all cases where
they are more stringent than those contained herein, and, where
state and federal limitations differ, the lower limit shall apply.
G. EXCESSIVE DISCHARGE
No user shall ever increase the use of potable or process water
or, in any way, attempt to dilute a discharge as a partial or complete
substitute for adequate treatment to achieve compliance with the
limitations contained in the Federal Categorical Pretreatment stan-
dards, or in any other pollutant-specific limitation developed by the
City or the state, including BOD and TSS.
NOTE; Dilution may, however, be acceptable as a means of
controlling some of the prohibited discharge levels use of which
shall be subject to the specific approval of the Superintendent.
14
H. ACCIDENTAL DISCHARGE
Each user shall provide protection from accidental discharge of
prohibited materials or other substances regulated by this ordinance.
The facilities to prevent accidental discharge of prohibited materials
shall be provided and maintained at the owner or user's own cost and
expense. Detailed plans showing facilities and operating procedures
to provide this protection shall be submitted to the City for review,
and shall be approved by the City before construction of the facility.
All existing users shall complete a plan by July l, 1983. No user
who commences contribution to the POTW after the effective date of
this chapter shall be permitted to introduce pollutants into the system
until accidental discharge procedures have been approvecl by the
City. Plans approved by or on file with State or Federal agencies will
be considered sufficient to meet ordinance requirements if reviewed
by and on file with the City. Review and approval of such plans and
operating procedures shall not relieve the industrial user from the
responsibility to modify the user's facility as necessary to meet the
requirements of this ordinarice. In the case of an accidental dis-
charge, it is the responsibility of the user to immediately telephone
and notify the POTW of the accident, specifying the following:
a) location of point of discharge;
b) type of waste or pollutant discharged;
c) concentration and volume of discharge;
d) corrective action taken at point of discharge.
In addition, within five (5) days following an accidental dis-
charge, the user shall submit to the Superintendent 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
POTW, fish kills, or any other damage to person or property; nor
shall such notification relieve the user of any fines, civil penalties,
or other liability which may be imposed by this article or other appli-
cable law.
Furthermore, a notice shall be posted with other emergency
phone numbers advising designated employees whom to call in the
event of a dangerous discharge. Employers shall insure that all
employees who may cause or suffer such a discharge to occur are
advised of the emergency notification procedure.
Complete compliance with this section along with a documented
and verified bonafide operating upset shall be an affirmative defense
to any enforcement action brought by the administration against the
user for any non-compliance with this ordinance or any Wastewater
Contribution Permit issued pursuant to this ordinance which arises
out of violations alleged to have occurred during the period of the
upset.
I. FEDERAL CATEGORICAL PRETREATMENT STANDARDS
When promulgated, Federal Categorical Pretreatment Standards
for a particular category, if more stringent than the limitations
imposed by this ordinance for users in that category or subcategory,
shall immediately supercede the limitations imposed under this
chapter. The Superintendent shall notify all affected users of the
applicable reporting requirements under 40 CFR, SEction 403.12.
J. MODIFICATION OF FEDERAL CATEGORICAL PRETREATMENT
STANDARDS
Where the City wastewater treatment system achieves consistent
removal of pollutants limited by federal pretreatment standards, the
City may apply to the Administrator of the EPA for modification of the
specific limit(s) in the federal pretreatment standards. "Consistent
15
removal" shall be defined as reduction in the amount of a pollutant or
alteration of the nature of the pollutant by the wastewater treatment
system to a less toxic or a harmless state in the effluent as defined
by the Code of Federal Regulations (CFR).
K. REQUIREMENTS FOR TRAPS
Any user discharging oil, sand, flammable wastes, grease or
wastes containing grease in amounts that will impede or stop the flow
in public sewers shall at his own cost and expense and as required
by the provisions herein provide interceptors or traps of a type and
capacity approved by the City with the following features :
1) Impervious material construction capable of withstanding
abrupt and extreme changes in temperature;
2) Watertight and equipped with easily removable covers
which, when bolted in place, shall be gastight and
watertight;
3) Located as to be readily and easily accessible for cleaning
and inspection;
4) Maintained by the owner or user at his own cost and
expense;
5) In continuous and efficient operation at all times.
Approval of traps and interceptors shall be obtained from the
City Engineer. Approval shall in no way relieve the user from
providing traps and/or interceptors of adequate size and design to
bring all discharges into compliance with this ordinance. The user
shall maintain for a period of at least the previous twelve (12) months
records of cleaning of any traps and/or interceptors in his use.
These records shall contain at a minimum the name and address of the
person performing the cleaning service and the dates the service is
performed.
A permit shall be required for operation of traps and
interceptors connected to the POTW when a wastewater contribution
permit is not in effect for the user. A yearly permit fee shall be
charged to cover periodic inspection. This fee shall appear on the
regular monthly bill unless otherwise directed by the Finance
Director.
SECTION .33 MONITORING PROVI5IONS.
A. INSPECTION AND SAMPLING AND RIGHT OF ENTRY
The City may inspect the facilities of every user to ascertain
whether the requirements of this ordinance are being met according to
the purposes herein stated. Persons or premises occupants where
wastewater is created or discharged shall allow the City or their
authorized representative(s) ready access at any and all reasonable
times to all parts of the premises necessary for the purpose of in-
spection, sampling, records examination or the performance of any of
their official duties. The City of Paris, Paris, Texas, the state
agencies with jurisdiction and the EPA shall have the right to set up
on the user's property such devices as are necessary to conduct
sampling inspection, compliance monitoring anci/or metering op-
erations. If a user has in force security measures requiring proper
identification and clearance prior to entry into their premises, the
user shall make any necessary arrangements with their security
service ( s) so that personnel from the City presenting suitable identi-
fication (or such personnel from state agencies or the EPA) will be
allowed to enter, without delay, for the purposes of performing their
specific responsibilities. In no case shall there be a delay of greater
than ten (10) minutes for access to control points or control manholes
and thirty (30) minutes for access to records or facility inspection.
Sampling shall be done on a 24-hour composite flow-weighted basis for
purposes of determination of surcharges when possible. When flow-
recording or measuring devices are not used on wastewater lines, the
16
best available data shall be used to compute the charges at the dis-
cretion of the Superintendent. No part of this ordinance shall be
interpreted to prevent non-flow-weighted composite or grab sampling
whenever necessary or required to monitor or check any user for
compliance with this ordinance.
B. SAMPLE ANALYSIS
Wastewater and waste samples will be collected and tests per-
formed by City personnel wherever feasible. The laboratory proce-
dures to be used in the examination of industrial or other wastes or
wastewater will be those set forth in "Standard Methods" as
previously defined in this ordinance. However, alternate methods for
certain analysis may be used when approved by the Superintendent.
For pretreatmer_t purposes, samples shall be taken at least twice
yearly by the City of the user if so designated by the
Superintendent. These two samples shall be paid for by the user.
Samples for the purpose of checking compliance shall be paid for by
the City if no violation is found and by the user if a violation
occurred. User shall also pay for samples to check violations. User
may use the two regular samples in the required compliance
reporting.
The Superintendent may at his discretion:
1) have the user sample at his discharge and have analysis
done at a mutually agreeable laboratory;
2) sample and send to a competent commercial or public labo-
ratory for analysis.
Any necessary quality assurance for pretreatment sampling and
analysis shall be consistent with those of 40 CFR 136 -"Guidelines
for Establishing Test Procedures for the Analysis of Pollutants",
et_seq.
C. MONITORING FACILITIES
'I'he City shall require to be provided and operated at the user's
own cost and expense monitoring facilities to allow inspection,
sampling, and flow measurement of the building sewer and/or internal
drain systems. The monitoring facility should normally be located on
the user's premises; however, when such location would be impractical
or cause undue hardship on the user, the City may allow the
construction of the facility in the public street or sidewalk area in a
location that will not be obstructed by landscaping or parked
vehicles. The above shall apply to both old and new users when
monitoring facilities are necessary.
VVhether constructed on public or private property, the sampling
and monitoring facilities shall be provided in accordance with the
city's requirements and all applicable local construction standards and
specifications. There shall be ample room in or near such control
manhole or facility to allow accurate sampling and preparation of
samples for analysis. The facility, sampling equipment and measuring
devices shall be maintained at all times in a safe and proper operating
condition at the expense of the user.
Plans and specifications for constructions of monitoring facilities
shall conform to City standards and shall be approved by the City
Engineer. Rental or lease of suitable equipment on an as-needed
basis in lieu of permanent installation may be acceptable subject to
approval by the Superintendent; such approval shall not release the
user from the requirement to provide sampling facilities secured and
protected access to the control point(s).
17
D. FLOW-MEASURING DEVICES
Users contributing 25,000 gallons per day of normal domestic
wastewater or its equivalent in BOD and/or suspended solids loading
and any user having a wastewater contribution permit shall provide at
the user's cost and expense a device for measuring wastewater flow.
Its specifications shall be approved by the City Engineer. Users
contributing less than 25,000 gallons per day have the option of
installing an approved flow measuring device. If no flow measuring
device is installed surcharges will be based on 100$ of water usage.
Any user desiring to have his regular wastewater charges based
on less than the percentage return in effect at that time shall install
at his own expense an approved flow measuring device or if the user
is able to furnish records and amounts of water usage incorporated in
final products not returned to the POTW verifiable by the City, he
may have his regular wastewater charges based on a percentage
return less than that in effect at the time subject to the approval of
the City Manager.
All flow meters and/or devices shall be installed so they may be
easily cleaned, serviced, inspected, and calibrated. Users shall
maintain such devices calibrated an in properly operating conditions
at all times. The Superintendent may inspect these devices for
compliance with this ordinance at his discretion.
E. PRETREATMENT
Users shall provide necessary wastewater pretreatment as
required to comply with this ordinance and shall achieve compliance
with all federal categorical pretreatment standards within the time
limitations as specified by the Federal Pretreatment Regulations. Any
facilities required to pretreat wastewater to a level acceptable to the
City shall be provided, operated and maintained at the user's cost
and expense. Detailed plans showing the pretreatment facilities and
their operating procedures shall be submitted to the City for review,
and shall be approved by the City before construction of the facility.
The review of such plans and operating procedure will in no way
relieve the user from the responsibility of modifying the facility as
necessary to produce an effluent acceptable to the City under the
provisions of this ordinance. Any subsequent changes in the pre-
treatment facilities or operating procedures shall be reported to and
acceptable to the City prior to the initiation of the changes.
The City shall annually publish in a local Paris, Texas,
newspaper a list of users which were in violation of any pretreatment
requirements or standards for forty-five (45) days or longer on any
one occasion during the previous twelve (12) months. The
notification shall also summarize any enforcement action taken against
the user ( s) during the same twelve (12) months.
All records relating to compliance with pretreatment standards
shall be maintained for a period of at least three years and be made
available to officials of the EPA, Texas Department of Water
Resources, or other agency with proper jurisdiction upon written
request.
18

SECTION .35 REPORTING REQUIREMENTS
A. COMPLIANCE DATE REPGRTING
Within ninety (90) days following the date for final compliance
with applicable National pretreatment standarcls or, in the case of a
new source, following commencement of the introduction of wastewater
into the POTW, any user subject to such pretreatment standards and
requirements shall submit to the Superintendent a report iridicating
the nature and concentration of all pollutants in the discharge from
the regulated process which are limited by those pretreatment stan-
dards and requirements. The report shall state the performance of
the user in consistently meeting the applicable pretreatment standards
and requirements and, if any, what additional pretreatment andlor
operation and maintenance is necessary to bring the user into compli-
ance with the applicable pretreatment standards or requirements.
This statement shall be signed by an authorized representative of the
industrial user and certified by a qualified professional engineer.
B. PERIODIC COMPLIANCE REPORTING
Any user subject to a National pretreatment standard, after the
compliance date of such pretreatment standard, or, in the case of a
new source, after commencing discharge into the POTW, shall submit
to the 5uperintendent during the months of June and December,
unless required more frequently in the pretreatment standard or by
the Superintendent, a report indicating the nature and concentration
of pollutants in the effluent which are limited by such pretreatment
standards. User may use the two required samples for this report.
In addition, this report shall include a record of all daily flows which
during the reporting period exceeded the average daily flow reported
in the Compliance Date Report (see previous section).
The Superintendent may impose mass limitations on users which
are using dilution to meet applicable pretreatment standards or re-
quirements, or in other cases, where the imposition of mass limitations
are appropriate. In such cases, the Periodic Compliance Report shall
indicate the mass of pollutants regulated by pretreatment standards in
the effluent of the user. These reports shall contain the results of
sampling and analysis of the discharge, including the flow and the
nature and concentration, or production and mass where requested by
the Superintendent, of pollutants contained herein which are limited
by the applicable pretreatment standards. The frequency of monitor-
ing shall be prescribed in the pretreatment standards. All analysis
shall be performed in accordance with procedures established by the
EPA pursuant to Section 304 (g) of the Act and contained in 40 CFR,
part 136 and amendments thereto or with any other test procedures
approved by the EPA. Sampling shall be performed in accordance
with the techniques approved by the EPA.
C. CONFIDENTIAL INFORMATION
It shall be the policy of the City not to require or accept confi-
dential information from industrial users unless necessary to meet
state or federal requirements or to stop or prevent interference or
damage to the POTW. Any information furnished to the City by an
industrial user which the user considers confidential shall be clearly
marked by the user as confidential. Information and data on a user
obtained from reports, questionnaires, permit applications, permits
and monitoring programs and from inspections shall be available to the
public or other governmental agency without restriction unless the
user specifically requests and is able to demonstrate to the satisfac-
tion of the City that the release of such information would divulge
information, processes or methods of production entitled to protection
as trade secrets of the user.
VJastewater constituents and characteristics will not be recognized
as confidential information. Informatior_ accepted by the City as
confidential will not be transmitted to any governmental agency or to
22
the general public by the City until and unless a ten (10) day noti-
fication is given to the user.
SECTION _.36 ENFORCEMENT PROVISIONS
A. CONTRACT AGREEMENTS
Na provision contained herein shall be construed as preventing
any agreement or arrangement between the City and any industrial
user whereby industrial waste of unusual strength or character may
be accepted by the City for treatment, subject to any applicable state
and/or federal limitations and requirements and to payment therefor
by the industrial user for all or some portion of the cost to the City
involved in the handling and treating of such industrial wastes, as
may be established by the City Council.
When discharges of waste of unusual strength or character are
accepted by the City for treatment, the City may enter into an agree-
ment or arrangement providing the following:
1) terms of acceptance by the City;
2) fees, charges and payments for the treatment of waste of
unusual stren.gth or character;
3) sewer connections, construction and procedures for dis-
charge in accordance with all applicable requirements of the
City code;
4) fees and charges for sampling, analysis and reporting
results of testing of discharge;

elements.
B. NOTIFICATION OF VIOLATION
Whenever the City finds that any user has violated or is violat-
ing this ordinance, wastewater contribution permit and/or any prohi-
bition, limitation or requirements herein, the City may serve upon
such person a written notice stating the nature of the violation.
Within thirty (30) days of the date of the notice, a plan for the
satisfactory correction thereof shall be submitted to the City by the
user. This thirty (30) day period does not relieve the user of any
liability for damages, fees, and other costs incurred by the City due
to the user's violation.
C. HARMFUL CONTRIBUTIONS
The Superintendent, with the recommendation of the City
Engineer and with the consent of the City Nianager, may order
suspensioxi of the water and/or wastewater treatment service and/or
revoke wastewater contribution permit when such suspension or
revocation is necessary, in the opinion of the Superintendent, to stop
an actual or threatened discharge which presents or may present an
imminent or substantial endangerment to the health or the welfare of
persons or the environment, cause interference to the POTW, or
cause the City to violate any condition of its NPDES permit.
Any person notified of an order to suspend the water and/or
wastewater treatment service and/or the wastewater contribution
permit shall immediately stop or eliminate the contribution. In the
event of the failure of the person to comply voluntarily with the
suspension order, the City shall take such steps as deemed necessary
including immediate suspension of water and/or wastewater treatment
service, to prevent or minimize damage to the POTW system or
endangerment to any individuals. The Superintendent may resend a
suspension order, if the harmful contribution is immediately and
voluntarily stopped and the Superintendent has reason to believe it
will not recur. The City shall reinstate the wastewater contribution
permit and/or the water and/or wastewater treatment service upon
proof of the elimination of the non-compliant discharge.
23
A detailed written statement submitted by the user describing
the causes of the harmful contribution and the measures taken to
prevent any future occurrence shall be submitted to the City within
fifteen (15) days of the date of the occurrence.
D. SHOW CAUSE HEARING
In the event of repeated unauthorized discharges , failure to
meet a compliance schedule, or any repeated violations of this ordi-
nance by a user, the Superintendent, with the recommendation of the
City Engineer and the consent of the City Manager, may order any
user to show cause why a proposed enforcement action should not be
taken. A notice shall be served on the user specifying the time and
place of a hearing to be held regarding the violation, the reasons
why the action is to be taken, the proposed enforcement action and
directing the user to show cause why the proposed enforcement action
should not be taken. The notice of the hearing shall be served
personally or by registered or certified mail (return receipt
requested) at least ten (10) days before the hearing. Service may be
made on any authorized representative of an industrial user.
The City Council shall appoint a hearing examiner to perform the
following functions :
1) issue in the name of the City Council notices of hearings
requesting the attendance and testimony of witnesses and
the production of any evidence relevant to any matter
involved in such hearings;
2) conduct the hearing;
3) deliver a transcript of the hearing and his recommendations
to the City Council f.or action thereon.
After the City Council has reviewed the evidence, it may issue
an order to the user responsible for the discharge directing that,
following a specified time period, the sewer service or water service
be discontinued unless adequate treatment facilities, devices or other
related appurtenances shall have been installed and existing treatment
facilities, devices or other related appurtenances are properly
operated. Further orders and directives as are necessary and
appropriate may be issued.
E. FEES AND CHARGES DUE TO VIOLATIONS
The City of Paris may recover all reasonable costs of repairing
damages to the City sewer system, costs of resampling, costs of
paying fines or penalties which result from a discharge not in
compliance with this ordinance, and any other costs incurred by the
City in controlling discharges in violation of this ordinance.
Billing for recovery of such costs shall be by letter to the
discharger, sent certified or registered mail, return receipt
requested, which states the specific violation(s), the damages and
penalties sustained by the City, the costs of those damages and
penalties, and the costs the City has determined as attributable to
the discharge and billed to the discharger.
The costs are due and payable by the discharger upon receipt of
the letter. Non-payment or disputes regarding the amount within ten
(10) days shall be cause for termination of water and/or wastewater
service. It shall be unlawful for anyone but an authorized City
employee to reconnect service. Any reconnection fees in effect are
applicable.
F. SURCHARGES
The City will accept BOD of up to 250 mg/1 and SS of up to 250
mg/1 as normal domestic wastewater. The City may elect to accept
BOD5 and SS in excess of 250 mg/l. BOD5 and SS over the value of
250 mg /1 shall be subject to an excessive strength operation and
24
maintenance surcharge. These surcharges shall be calculated on a
monthly basis using metered wastewater contribution as a volume
factor, if provided by the user, or 100$ of water usage.
The total fat, oil, and grease allowed by this ordinance is 100
mg/1, whether free or emulsified. When this parameter is determined
on a composite sample, any amount over the allowable limit shall be
added in mg/1 to the BOD5 and SS values used for purposes of
surcharge calculation.
1) Unless otherwise specified, samples shall be twenty-four
(24) hour composites. When a flow-recording device is
provided the samples may be flow-weighted; otherwise, a
simple composite sample shall be used.
2) The surcharges shall be based on all samples taken in the
previous month or the most recent sample available. In no
case shall the sampling basis be less than two (2) twenty-
four (24) hour composite samples per year if a surcharge is
levied.
3) The City may elect to set a minimum surcharge. Regular
sampling may be suspended on those users, considered by
the Superintendent to be consistently below the minimum
surcharge. When sampling has been suspended, periodic
grab samples may be used to determine if regular sampling
should be reinstated.
The user may elect to have his discharge resampled by the City
for purposes of surcharge recalculation. The City shall retake one
sample for each sample taken in the normal sampling program for a
charge equal to the City's expense. Sampling at the request of the
user in greater frequency than stated above shall be elective on the
part of the Superintendent; charges for such sampling shall be at a
flat rate of three times the City's cost.
The user may request, no later than the onset of sampling, a
split or duplicate of any sample taken by the City for surcharge
calculation or compliance with any portion of this ordinance.

4) CALCULATION OF EXCESSIVE STRENGTH SURCHARGE
SC- [(F'OD5 mg/1 - 250 mg/1) SCRBOD 5 +(TSS mg/1 - 250 mg/1)
SCRTSSI X P,hG
SC = Surcharge
BOD5 mg/1 = User BOD5 for surcharge calculation
250 mg/1 = allowable BODS and suspended solids concentration
without surcharge
SCRBOD = graduated charge rate for BODS

T5S mg/1 = User TSS for surcharge calculation
MG = User wastewater contribution in million gallons for the
month or the user water usage whichever is applicable.
SCP.SS = Graduated charge rate for 'I'SS
NOTE: The SCRSS and SCRBODS are rates based on one (1)
mg/1 in one (1) million gallons of wastewater.
5, SHORTENED CAPACITY LIFE SURCHARGE
Since BOD and SS concentrations in excess of 250 mg/1 will tend
to use up the capacity of the treatment plant, there is a cost
incurred for the shortened useful capacity of the treatment plant,
which shall be recovered as follows:
A. Determination of monthly average BOD5 of the treatment
plant influent through twenty-four hour composite sampling
and lab analysis reported in pounds per day.
B. Using a predetermined strength for normal domestic
wastewater from the City of Paris, Paris, Texas, industrial
contribution will be determined by calculating the difference
between the actual BOD and SS received and the amount
that should have been received accarding to normal domestic
strength.
C. Each month, using the plant design capcity, the amount in
excess of normal domestic wastewater will be determined as
a percentage of plant capacity; percentage will be assumed
to be the reduction in useful plant capacity life, to be
converted to years using plant design criteria.
D. A difference in debt services due to treatment plant
between designed useful capacity life and calculated useful
capacity life for that month using the CRF Formula i(l+i) n
(l+i~~ 1
will be determined.
26
E. This recovery figure will be spread over those industries
exceeding normal domestic wastewater limits according to
their contributions to the total excessive strength flows.
6. CALCULATION OF SHORTENED CAPACITY LIFE
SURCHARGE
A= Average monthly monthly measured BODS at wastewater plant
(lbs. per day)
B= BOD in pounds at wastewater plant if received at
predetermined normal domestic wastewater strength.
C= Design life of wastewater plant (month).
E= Adjusted capacity life (months)
F= Construction cost for treatment plant.
G= Amount in dollars to be distributed over excessive strength
industry for any given month.
H= Industry BOD5 contribution in excess of normal domestic
wastewater (lbs).
I= Shortened capacity life surcharge.
E= B (C)
A
G= F i( l+i ) E -F C
(1+i)E-1 (l+i) C -1
I= (G) ~c H
Shortened capacity life surcliarge shall be calculated monthly.
7. TOTAL SURCHARGES
a. Total surcharge shall be the sum of the excessive strength
surcharge plus the shortened capacity life surcharge.
b. Excessive strength surcharge rates will be recalculated at
the beginning of each fiscal year using the actual costs
from the previous year with such rate becoming effective
September 1. Excessive strength surcharge rates shall be
based on cost to treat.
G. LEGAL ACTIUN
If any person discharges industrial or other wastes or sewage
into the City's wastewater facilities contrary to the provisions of this
ordinance, federal or state pretreatment requirements, or ariy order
of the City, the City Attorney may commence an action for
appropriate legal and/or equitable relief in a court of competent
jurisdiction. The City may recover reasonable attorney's fees, court
costs, court reporter's fees and other expenses of litigation.
H. CIVIL PENALTIES
