First Reading of Ordinance No. 020, 2010 Amending Chapter 26 of the City Code Relating to Industrial Pretreatment
Local Limits and Requirements.
EXECUTIVE SUMMARY
This Ordinance amends the City Code to provide legal authority to implement and enforce revised Federal
pretreatment regulations. The Ordinance also contains revised pollutant local limits applicable to industrial wastewater
dischargers. The modifications and revised local limits were developed based upon Environmental Protection Agency
(EPA) Region VIII requirements and guidance and will be subject to EPA approval between the First and Second
Reading of the Ordinance.
BACKGROUND / DISCUSSION
Federal and State regulations require the City to operate an EPA approved Industrial Pretreatment Program (IPP).
The objective of the IPP is to control the discharge of wastewater pollutants from industrial and commercial sources
in order to protect the quality of receiving water and biosolids, prevent interference with wastewater treatment and
infrastructure, and protect worker health and safety. In Colorado, EPA Region VIII oversees IPPs. EPA oversight is
implemented via reports, audits, and inspections.
The proposed modifications to Fort Collins City Code,Article IV,Wastewater are the result of two separate events that
coincided. The events were an EPA audit of the IPP and the reissuing of the National Pollutant Discharge Elimination
System (NPDES) permits for the City wastewater treatment facilities.
The City IPP was audited by the EPA in 2009. One purpose of the audit was to review Chapter 26 of the City Code
relating to wastewater and provide guidance for the modifications needed to ensure the Code provides legal authority
to enforce Federal pretreatment regulations. The Federal regulations were revised in 2006, and it is an EPA
requirement that the Code be modified to align with the revised Federal regulations. After reviewing the Code,the EPA
provided a list of required modifications. All the modifications submitted in this agenda item summary are the result
of EPA requirements, with the exception of twelve amended definitions and a change to Sec. 26-324 (4). In most
cases, modifications were made using language taken directly from Federal regulations or EPA model pretreatment
ordinance.
Federal regulations also require the City to develop technically based pollutant limitations for significant industrial users
of the wastewater collection system. These limitations are referred to as local limits. It is an EPA requirement that
local limits must be re-evaluated when the NPDES permit for a wastewater treatment facility is reissued. The NPDES
permits for the City wastewater treatment facilities were reissued November 2008,and revision of local limits became
necessary. Staff developed the revised local limits using EPA Region VIII guidance and a spreadsheet provided by
the EPA. Data characterizing the wastewater system were entered into the spreadsheet to calculate the local limits.
To calculate local limits,the amount of each regulated pollutant that can be allowed to enter the wastewater treatment
system is determined, based upon the most stringent applicable water quality or biosolids standard. This amount is
referred to as the pollutant's Maximum Allowable Headworks Load (MAHL). A portion of each MAHL is reserved for
the pollutant load present in domestic wastewater. Additional portions are taken by hauled waste and a growth/safety
factor. After these portions have been removed,the remaining MAHL is the amount that may be allocated to industrial
and commercial sources.The allocation to industrial sources is expressed as a concentration-based local limit. The
allocation to commercial sources is a mass limitation expressed in pounds per day. Attachment 1 illustrates an MAHL
with allocations to different wastewater sources.
March 2, 2010 -2- ITEM 15
Local limits apply only to significant industrial users (SIUs) of the City wastewater system. The City controls the
discharge of wastewater pollutants from an SIU by issuing an industrial discharge permit to the SIU. Currently, there
are fourteen SIUs regulated by the City.
City local limits were last revised in 2000. Changes in water quality standards, biosolids standards, wastewater
volume, and pollutant removal efficiencies have contributed to changes in the revised local limits. Seven limits are
more stringent, seven are less stringent, six are unchanged, and the iron limit has been removed. Attachment 2 is
a comparison of the revised local limits and those currently in effect.Attachment 2 also provides additional discussion
of factors that influence change in local limits.
Historical data from SIUs indicates industries will be in compliance with the more stringent limits without the need to
change current practices or encounter additional expenses. Data reviewed back several years found only two
additional permit violations that would have occurred as a result of the more stringent limits. It is also not expected
that SIUs will be able to relax their current pollutant control practices as a result of the less stringent limits.
After reviewing the Code, the EPA recommended the commercial pollutant allocations be removed from the Code.
The allocations are for the discharge from all commercial wastewater sources combined. The allocations are not limits
that are applicable to an individual commercial wastewater discharger. There is no practical application for having the
allocations in the Code. Staff agrees with the EPA recommendation to remove the commercial pollutant allocations
from City Code.
The EPA completed a preliminary review of the Code modifications and provided a few additional requirements. Staff
has incorporated the additional requirements into the proposed modifications. Between First and Second Readingsof
the Ordinance, the EPA will conduct a final review of the modifications. If the EPA approves the modifications, the
EPA will provide public notice of the modifications in the Coloradoan. There will be a thirty-day period for comment
following the public notice. It will be necessary to delay the Second Reading of the Ordinance to April 20, 2010, in
order to allow the EPA time to complete the review and public notice.
FINANCIAL IMPACT
Industrial and commercial users of the wastewater system will not experience a financial impact as a result of the Code
modifications. The users will not need to alter current practices in order to comply with the modifications. They will
also not be able to relax current practices as a result of the modifications. SIUs are currently discharging wastewater
that complies with the revised local limits.
There will be no financial impact to the City as result of the proposed modifications. No changes will be made to the
routine operation of the IPP or wastewater treatment facilities. It is not expected that there will be any increase in
violations of the wastewater Code.
SUSTAINABILITY: ECONOMIC, ENVIRONMENTAL AND SOCIAL IMPACTS
The objective of the IPP is to control the discharge of wastewater pollutants from industrial and commercial sources
in order to protect the quality of receiving water and biosolids, prevent interference with wastewater treatment and
infrastructure, and protect worker health and safety. Accomplishment of this objective positively impacts the
environmental, social, and economic health of Fort Collins. The proposed modifications were developed with EPA
guidance and will strengthen legal authority to accomplish the objectives of the IPP.
STAFF RECOMMENDATION
Staff recommends adoption of the Ordinance on First Reading.

MAHL Illustration
The Maximum Allowable Headworks Load (MAHL) is the amount of pollutant that may
be discharged into the wastewater system without causing a violation of the most
stringent applicable environmental standard. A MAHL is expressed as lbs/day of a
specific pollutant. Data characterizing the wastewater system is used to calculate the
MAHL and pollutant loading allocations for different wastewater sources . The chart
below illustrates a MAHL and the allocation of pollutant loading. The allocation
proportions may vary for each pollutant.

Factors influencing change to local limits
Change to the local limit for a pollutant is influenced by changes to water quality
standards, biosolids standards, wastewater flow volume, source of wastewater flow,
biosolids production, wastewater treatment pollutant removal efficiency, and the MAHL
growth/safety factor. Many of these factors have changed since local limits were last
calculated in 2000. The combined influence of the factors determines any change to the
local limit.
Change to manganese local limit
The significant difference between the revised and current manganese local limit is due to
an error in the water quality standard used for the 2000 calculation. The water quality
standard used for manganese in the 2000 calculation was intended for use with irrigation
water applied to soils with pH less than six. Front Range soils are alkaline and have a pH
significantly greater than six.

Attachment 2
Removal of iron local limit
Staff recommends the local limit for iron be removed from Code. Iron, at the rate of 140
lbs/day, is added to the City wastewater treatment process to control formation of
hydrogen sulfide. Hydrogen sulfide is a particularly dangerous gas. At low
concentrations it causes "rotten eggs" sewer odor. At moderate concentrations it quickly
anesthetizes the sense of smell and is very toxic. Hydrogen sulfide also reacts with
moisture to form sulfuric acid and cause corrosion of infrastructure.
Even with iron added as part of the treatment process, the likelihood of exceeding
environmental standards for iron is extremely low. It is not reasonable to implement an
iron local limit when iron is routinely added to the treatment process. Staff and EPA
discussed removing the iron local limit from Code and agreed the limit is not needed.

Attachment 3
Excerpt from Unapproved Water Board Minutes,January 28, 2010
Industrial Pretreatment Code Changes
(Presentation available upon request)
Steve Comstock, Water Reclamation and Biosolids Manager, introduced the topic. The
City Industrial Pretreatment Program was audited by the Environmental Protection
Agency (EPA) in 2009. After reviewing the City Code, EPA provided a list of required
modifications. Staff also identified additional changes needed to support the
modifications or update the Code. EPA will provide public notice of the modifications in
the Coloradoan.
Ron Russell, Industrial Pretreatment Coordinator/Technical Services Supervisor,
provided information on the Code changes. EPA required 34 of the 46 changes made to
the definitions and all the other changes except for Sec. 26-324(4). The Code
modifications apply to dischargers of non-domestic (commercial and industrial)
wastewater.
The City is required to develop technically based pollutant limitations, known as local
limits. These limits must be evaluated when NPDES (National Pollutant Discharge
Elimination System) permits are reissued and apply only to significant industrial users
(the City currently has 14 of these users). There should be no additional costs to these
users. The NPDES permits were reissued November 2008.
In response to questions from the board, Mr. Russell noted the following:
• The modifications will be codified in approximately ten days following approval
by Council. Between the first and second readings, EPA will public notice the
modifications with a public comment period of thirty days.
• Industrial Pretreatment Discharge Permit price will not change as a result of these
modifications.
• Copper, lead and zinc compliance limits will be reduced, which may cause some
concern. However, historically, users have been below the limits.
• A number of environmental standards may apply to a pollutant. Local limits are
calculated based upon the most stringent environmental standard for a pollutant.
A spreadsheet furnished by EPA is used to calculate the local limit. The
spreadsheet determines the most stringent environmental standard and using
pollutant removal efficiency, wastewater flows, biosolids production, and
contribution of pollutant from domestic users, it will calculate the pounds per day
of pollutant to allocate to industrial users. Removal efficiency indicates the fate
of the pollutant during treatment. Non-biodegradable pollutants with high
removal,efficiency go into the biosolids, and pollutants with low removal
efficiency go into the effluent
• If a pollutant is causing a problem and approaching Maximum Allowable
Headworks Load (1VMAHL), staff will look for the source and address the sector
involved.

to read as follows :
Sec. 26-317. Monitoring facilities.
(a) Whenever required by the General Manager, an industrial user shall
provide, maintain and operate at its sole expense monitoring equipment and facilities
sufficient to allow the safe inspection, sampling and flow measurements of the
private sewer or internal drainage systems . The monitoring facility should normally
be a monitoring manhole situated on the industrial user's premises , but the utility
may, when such a location would be impractical or cause undue hardship on the
industrial user, allow the facility to be constructed in the public street or sidewalk
area and located so that it will not be obstructed by landscaping or parked vehicles .
Whenever required by the General Manager, a monitoring manhole shall be installed
for each separate regulated discharge to the public sewer in accordance with plans
and specifications approved by the General Manager. The decision to require
installation of monitoring equipment will consider factors such as sampling
frequency, parameters, economics and physical limitations of the plant site .
- 13 -
(b) There shall be ample room in or near the monitoring manhole or facility to
allow accurate sampling and preparation of samples for analysis, and such manhole
shall be safely, easily and independently accessible to authorized representatives of
the utility during normal business hours . The General Manager may require that the
monitoring equipment be installed in an enclosed facility outside of the manhole.
(c) Whether constructed on public or private property, the sampling and
monitoring equipment and facilities shall be provided in accordance with the utility's
requirements and all applicable local construction standards and specifications.
Construction shall be completed within sixty (60) days following written notification
by the General Manager of the requirement for installation.
(d) Each monitoring manhole shall contain a Palmer-Bowlus flume or similar
device approved by the General Manager with a recording and totalizing register for
measurement of the liquid quantity. At the discretion of the General Manager, the
metered water supply to the industrial plant or a measurable adjustment thereof may
be used to determine the liquid waste quantity.
Section 6 . That Section 26-318 of the Code of the City of Fort Collins is hereby amended
to read as follows :
Sec . 26-318. Sampling and analysis .
(a) Each monitoring manhole shall contain a Palmer-Bowins
device approved by the 6eneral Manager with a recording and totalizing register fo
measurement of the liquid quantity. At the discretion of the 6eneral Manager, the
be used to determine the liquid waste quantity. Samples shall be collected, handled,
managed and documented in a manner designed to guarantee the identity and
integrity of the sample or data from collection through reporting of the test results .
The chronological history of the sample or data must be maintained and documented.
Chain-of-custody documents are required for all permit compliance samples and
shall include the name or initials of the person collecting the sample, each person or
entity subsequently having custody of it, dates the items were collected or
transferred, the collection location, a brief description of the item, and a sample
identification number.
(b) Samples that are representative of the monitored discharge shall be taken
from the required monitoring nmnhofcpoint and properly preserved in accordance
with standard methods . Grab samples must be used for pH, cyanide, total phenols,
oil and grease, sulfide and volatile organics . For all other pollutants, twenty-four-
hour composite samples must be obtained through flow-proportional composite
sampling techniques where feasible . The General Manager may waive flow-
proportional composite sampling for any industrial user that demonstrates that such
sampling is infeasible . In such cases, samples may be obtained through time-
proportional composite sampling techniques or through a minimum of four (4) grab
- 14-
samples where the user demonstrates that such sampling method will provide a
representative sample of the volume and nature of the effluent being discharged.
Grab samples may be required whenever the General Manager determines that
composite samples are inappropriate . All measurements, tests and analyses of the
characteristics of water and wastes to which reference is made in this Article shall
be determined in accordance with procedures established by the EPA pursuant to
Section 304(h) of the act and contained in 40 C .F .R. , Part 136, as amended. If no
special monitoring facility has been required, the point of sampling shall be as
specified by the General Manager.
(c) The General Manager shall determine the measurements and analyses
required and the frequency of sampling for each significant industrial user and
include them as conditions of the user's industrial discharge permit. The General
Manager may impose mass limitations on industrial users that use flow equalization
to meet applicable pretreatment standards or requirements and may impose them in
other cases where mass limitations are appropriate .
(d) The industrial user may be required by the utility to perform sampling, flow
metering and other self-monitoring at the user's own expense. The industrial user
may also be required to deliver aliquots of samples to the utility's laboratory for
optional analysis . Any user may contract with a private entity to provide such
services as deemed necessary, including but not limited to the following :
( 1 ) Monitoring equipment;
(2) Sampling; and
(3 ) Laboratory analysis .
(e) The industrial user's sampling methods, frequency of sampling and analysis
of samples shall be subject to inspection and verification at any time. The industrial
user shall maintain records of all information, resulting from its self-monitoring
activities. Such records shall include for all samples :
( 1 ) Dates , times, places and methods of sampling and the name of the person
taking the sample ;
(2) Dates and analytical methods/techniques used for analysis and who
performed the analysis ;
(3 ) Results of the analysis .
(f) If sampling indicates a violation, the industrial user shall resample and
resubmit the results of the second sample to the utility within thirty (30) days after
becoming aware of the violation. Routine, scheduled sampling may be used to meet
this requirement. The industrial user may not be required to resample if the utility
- 15 -
has performed sampling within thirty (30) days of the user becoming aware of the
violation. The industrial user may, however, be required to reimburse the utility for
the costs to the utility for such sampling.
(g) If the industrial user monitors more frequently than required any of the
pollutants it is required to monitor, and uses test methods prescribed by 40 C .F .R.
Part 136 or otherwise approved by EPA or specified in the industrial user' s permit,
the results of such additional monitoring shall be reported in the self-monitoring
results submitted to the utility and shall be considered in determining compliance
with the applicable discharge limits . Monitoring for pollutants upstream of the
sample locations specified in the permit is considered process control and is exempt
from the requirements of this Subsection.
(#h) Any industrial user subject to the industrial pretreatment reporting
requirements established by this Article shall be required to retain, for a period of
five (5) years, any records of the monitoring activities and results (whether or not
such monitoring activities are required by this Section) and shall make such records
available for inspection and copying by the General Manager. Said period of
retention shall be extended to include the pendency of any litigation existing between
the user and the utility or EPA or the Colorado Department of Public Health and
Environment regarding the requirements of the industrial pretreatment program as
they relate to the industrial user, or when requested by the General Manager.

compliance with the applicable pretreatment standards and requirements . The report
shall indicate the results of sampling and analysis of the discharge from each
regulated process stream, including the average and maximum daily now and the
nature and quantity of the pollutants limited by the standard. The report shall also
state whether the applicable pretreatment standards or requirements are being met
on a consistent basis and, if not, what additional operation and maintenance and/or
- 16-
pretreatment is necessary to bring the user into compliance . This statement shall be
signed by an authorized representative of the industrial user and certified to by a
qualified professional. In the case of a new source, the industrial user shall file the
report required by this Subsection within ninety (90) days of introducing industrial
wastewater into the wastewater utility, together with such information as may be
necessary to create a baseline report for monitoring compliance.
(c) Periodic compliance reports. After submitting the compliance date report,
an industrial user subject to a pretreatment standard shall report the results of self-
monitoring at least semiannually to verify continued compliance with the limits
contained in the standard. These reports shall be submitted to the General Manager
during the months of June and December, unless required more frequently in the
pretreatment standard or by the General Manager, indicating for each regulated

notify the utility of any change in discharge location, or any production increases,
or process modifications, that will result in substantially new, different, or increased
- 17-
discharge of pollutants . Process modifications include, but are not limited to, the
introduction of new pollutants not previously reported by the industrial user or any
other modification that may result in a discharge of a quantity or quality substantially
different from that authorized by the applicable permit.
(f) Reports of other discharges . An industrial user shall immediately notify the
utility of any discharge that could cause disruption of or damage to the utility ' s
wastewater collection system, including not limited to any slug loadings , spills, or
discharges not otherwise authorized by the applicable permit.
