towns were looked at and about new distillery/brewing companies coming in. Joe and
Michael provided responses that an educational approach will be used going forward and
the same rules will apply to new and current distilleries/breweries.
Melinda McWilliams questioned the timeframe for the project which was 3-5 years. Joe
explained that he would like the new engineering firm to review plant before just jumping in
on the project.
Discussion of cost for Option 1 and 2, passing the cost on through districts and handling
violations going forward took place.
There was some confusion between Option 1 versus 2. Joe explained the difference in how
the waste is disposed of correctly for both options.

a. Staff Briefing
b. JFOC Vote to Approve/Deny Study
Melinda conceded that this was brought forth by WPR. Art expressed concerns about staff
transitions and issues that were never addressed previously...specifically distilleries and
breweries. All agreed that this still needs more discussion.
Philip Vandernail asked about independent management and Michael responded that there
has been a breakdown in communication between managers. The complaints and
grievances need to be addressed with the TOF manager and not amongst the members if
they are to be corrected.
Further debate ensued regarding the lack of communication between the districts and the
managing entity, TOF.
Rob Clemens gave an overview from a Finance/HR Director's viewpoint regarding changing
management.
JFOC members agreed to defer item to the next meeting for more information to be
provided.

Contractor are sometimes referred to herein individually as a "Party" and collectively as the
"Parties").
WITNESSETH:
In consideration of the mutual covenants and obligations herein expressed, it is agreed by
and between the Parties as follows:
1. Scope of Services. The Contractor agrees to provide services related to the following scope of
services: emergency services and small projects on an as needed basis. The scope of services
referenced above along with any Additional Scope of Services is hereinafter referred to as the
"Scope of Services." All provisions of the Additional Scope of Services, including without
limitation any terms and conditions included therein, shall be subject to the provisions of this
Agreement. In the event of any inconsistency between the provisions of this Agreement and
any Additional Scope of Services, the provisions contained within this Agreement shall control.
2. Time of Commencement and Completion of Services. The services to be performed pursuant
to this Agreement shall be initiated no later than December 31, 2023. Services shall be
accomplished on an as needed basis at the direction of the Principal.
3. Early Termination by Principal. Notwithstanding the time periods contained herein,the Principal
may terminate this Agreement at any time without cause by providing written notice of
termination to the Contractor. Such notice shall be delivered at least three (3) days prior to the
termination date contained in said notice unless otherwise agreed in writing by the Parties. In
the event of any such early termination by the Principal, the Contractor shall be paid for services
rendered prior to the date of termination, subject only to the satisfactory performance of the
Contractor"s obligations under this Agreement. Such payment shall be the Contractor"s sole
right and remedy for such termination.
4. Suspension. Without terminating this Agreement or breaching its obligations hereunder,the
Principal may, at its convenience, suspend the services of the Contractor by giving the
Contractor written notice one day in advance of the suspension date. Upon receipt of such
notice, the Contractor shall cease its work in as efficient a manner as possible so as to keep
its total charges to the Principal for services under this Agreement to the minimum. No work
shall be performed during such suspension except with prior written authorization by the

Services. All requests for contract interpretations,change orders, and other clarification or
instruction shall be directed to the Principal Representative.

Principal. The Contractor accepts the relationship of trust and confidence established between
the Parties. The Contractor shall use its best efforts and shall perform the services hereunder at
or above the standard of care of those in its profession or industry providing similar services in

located shall be applicable to such services.
10. Accuracy of Work. The Contractor represents, covenants and agrees that its work will be
accurate and free from any material errors. The Principal's approval shall not diminish or release

harmless the Principal from any and all damages and liabilities arising from the Contractor"s
performance of the Scope of Services. As part of this obligation, the Contractor shall
compensate the Principal for the time, if any, spent by its legal counsel in connection with such
claims or actions. If an Additional Scope of Services contains any provisions purporting to
require the Principal to defend, indemnify, or hold harmless the Contractor or purporting to
effect a waiver or limitation of the Contractor's liability (either by type of liability or a mount), the
Principal does not agree or accept such provisions and such provisions are not part of the

execution, and enforcement of this Agreement. Venue for any dispute between the Parties
arising out of or relating to this Agreement shall be in the State of Colorado District Court for the
county in which the Principal "s mailing address is located.
22. Severability. In the event any provision of this Agreement shall be held invalid or unenforceable
by any court of competent jurisdiction, such holding shall not invalidate or render unenforceable
any other provision of this Agreement.
23. Annual Appropriation. The Principal's obligations hereunder are subject to the annual
appropriation of funds necessary for the performance thereof, which appropriations shall be
made in the sole discretion of the Principal's Board of Directors.

Upper Fraser Valley WWTP Evaluation
1. Detailed evaluation recommendation follow-up status
This report provides a follow-up status of the recommendations provided in the March 6, 2023 Upper
Fraser Valley WWTP evaluation report to Grand County Water & Sanitation District #1.
Initial Recommendation
1. Repairs to the North aeration basin air header need to be completed to ensure
peak loading can be treated adequately. Data indicates that both activated
sludge trains need to be in service to maintain proper treatment at peak loads.
This will allow for additional air to be added to the system during peak loading
periods.
Status: Implemented
During the site visit on July 17, 2023, both aeration basins were on line. The air header to the North
aeration basin has been repaired and the north aeration basin has been in service for several months.
The mixing pattern on the north aeration based was very consistent and appeared to be in very good
condition. The anoxic zone of the north aeration train is currently being used as additional aerobic
aeration. This is an operational decision based on the total nitrogen limits, which were under the discharge
limits and can be changed at any time if the operations staff needs additional denitrification.
As discussed in the original evaluation, the facility has an average 30 -day Biological Oxygen Demand
(BOD) loading of 1,329 Ibs/day and peak 30 -day loading of 1,920 Ibs/day. Each aeration basin has a
treatment capacity of approx. 2,085 Ibs/day. Because the peak 30 -day loading rates are very close to the
capacity of one (1) aeration train, it is recommended that both aeration basins be operated all year around
to accommodate the peak loadings that have occurred.
The question of using the 7 -day BOD loading rates was discussed as a better parameter to determine if
additional capacity was needed. Additional analysis on the previous data evaluated during the initial
evaluation shows that the 7 -day BOD average loading rate from January to September of 2022 was
2,009 Ibs/day although slightly higher than the 30 -day average loading rate, it is still well under the
design and permitted loading rate in the Colorado discharge permit C00040142 for the plant and even
if used would not indicate that additional capacity was required. It does further indicate the need for both
aeration basins to be in service all year.
Initial Recommendation
2. Repairs to the south aerobic digester need to be completed to minimize solids
disposal as well as ensure class B sludge requirements are maintained.
Status: Not implemented
During the site visit on July 17, 2023, the south aerobic digester repairs had not been completed.
The south digester aeration piping has been repaired and a new mixer motor was received, however the
mixer motor had not been installed. The south digester is currently being used as for extra sludge storage
and decanting. The operators are transferring solids back and forth from the north and south digester to
obtain some mixing and aeration. It should be noted that the solids treatment process could create odors
if the mixing and aeration of the south digester is not maintained at proper levels of dissolved oxygen
and/or the north digester is loaded beyond its treatment capacity and unable to maintain proper dissolved
oxygen levels.
Completing the repairs on the south digester should be high priority for the following reasons.
• The present operations could create septic conditions, which could create odors from high levels of
hydrogen sulfites.
• The purpose of the digester is to reduce the total volume of solids generated at the plant and ensure
class B sludge is generated for beneficial reuse. Historical data prior to 2022 indicates that the volatile
solids reduction with both digesters operating normally was approximately 55 percent. Recent data
230726133549_9eb9d070 5
Upper Fraser Valley WWTP Evaluation
shows a volatile solids reduction of approximately 38 percent. The lower volatile solids reduction can
cause the total volume of solids for disposal to increase for two reasons:
- Reduced destruction of solids
- Undigested solids are harder to dewater, leaving more water in the sludge to be hauled.
During the walkthough, we discussed the possibility of keeping a spare motor onsite for the digesters.
Although there are no specific requirements, the normal process to determine what is considered a critical
spare part has several factors to consider for keeping a spare motor for the digester on site such as:
a. Compliant operations. Number of days that equipment or parts can be out of service and still be able
to maintain all regulatory or in-house required compliance parameters vs. number of days to obtain a
spare part. If the repair or replacement lead time is longer than the time it can be out of service to
ensure compliance, the spare part should be on site. For the digester motor, the compliance
consideration would be to maintain class B sludge for disposal. Because the current plant loading
and/or digester loading are within the capacity of one digester, this consideration would not
specifically indicate that a spare motor should be onsite.
b. Cost. Cost of investment for the spare part vs. cost of having the equipment out of service. Specifically
related to the digester motor, if the cost of hauling and disposal of extra solids generated is greater
than the cost (or loss of use) of the money invested for the spare motor over the down time, or
anticipated lead time to obtain a motor or repair the motor, consideration should be given keeping a
spare onsite.
c. Equipment age. Even with excellent preventive maintenance practices, equipment will wear out and
require replacement. Specifically related to the digester motor, the north digester motor failed and
was replaced with the one that was on the south digester which is approximately the same age and
potentially indicate that it is approaching the end of its useful life. With this in consideration it can be
reasonably anticipated that the motor currently in use on the north digester may fail within a few
years. Noting that the lead time on the delivery of the new motor recently obtained was 18 months, a
spare motor should be considered now.
d. Equipment obsolescence and technology changes. This factor should be considered regarding any
spare part. If the equipment is a one -of -a -kind or sole source supplier and has been discontinued, a
spare should be considered. This most likely would not be a consideration for the digester motor.
However, mounting alignment for the base may need to be considered if a like motor is not available.
e. Other social and economic considerations. In addition to compliance or cost considerations other
social or economical considerations should be factored into the decision such as safety concerns,
odor concerns, how the out of service equipment affects other processes and staffing requirements to
operate the plant if the equipment is out of service.
A cost -only example for the digester motor is discussed in the following:
• The anticipated remaining life of the current (old) motor is 3 years
• Cost of the motor in 2023 dollars at $50,000, $100,000 or $245,000
• Interest rate to borrow money (or loss of usage of money) is 4 percent
• Additional solids generated per year if the digester is out of service is 40 tons/year
• Solids concentration at 20 percent dry, which equates to 200 wet tons to dispose of per year, or
300 wet tons over 18 months
• Cost per ton of sludge disposal is $230 per wet ton
• Lead time to procure a new motor is 18 months
• Inflation rate at 5 percent

Using this example, unless the motor costs more than $245,000, it would be worth having a spare on site.
The analysis can be used for any critical piece of equipment or spare part.
Initial Recommendation
3. Although the current flow and loading does not indicate the batch decanter
train is needed, consider completing the repairs and installation of the mixers
and aerators to allow utilization of the BD train for a backup when repairs to
the aeration trains are required or to be used with peak loading and flows,
if needed.
Status: Not implemented
During the site visit on July 17, 2023, we observed that no change has been made to the operability of the
Batch Decanter. The recommendation was presented as a consideration and would require additional
engineering and design studies, which could take several years to complete. This recommendation was
provided such that there would be an alternative process to accommodate high loading treatment
diversion as well as providing sufficient treatment capacity should repairs be needed for either of the
activated sludge trains. This recommendation could take several years to complete.
Initial Recommendation
4. Consider installation of an inline COD analyzer on the influent and install the
capabilities to automatically divert peak/sludge loads to the BD when
completed.
Status: Not implemented
During the site visit on July 17, 2023, we noted there was no additional automated monitoring of the raw
water. Staff continue to analyze the daily raw water composite sample in the laboratory. We made this
recommendation because of the high daily loadings the plant has experienced in the past. The intent was
that if high loads were detected, it would be possible to utilize the Batch Decanter to treat the high loads
but this can't be implemented until the Batch Decanter is operational. This recommendation would require
additional engineering and design to be completed fully.
Even without the capability to divert flow to the Batch Decanter, the installation of an inline COD analyzer
would provide real time information of potential high loads which would allow the operations staff to react
to and make adjustment to the process as required.
Initial Recommendation
5. Consider modifications to the secondary clarifier inlet chamber to facilitate use
of both secondary clarifiers when only one aeration basin is in service.
Status: Not implemented
230726133549_9eb9d070 7
Upper Fraser Valley WWTP Evaluation
During the site visit on July 17, 2023, we observed that no modification to the secondary clarifiers were
made. As noted in the evaluation report, the current configuration of each of the activated sludge basin
discharges is followed by a dedicated secondary clarifier. This configuration limits the flexibility of the
process trains and should either of the aeration basis be offline and the opposite secondary clarifier be out
of service, the process could experience significant carryover of solids out of the secondary clarifier.
This recommendation would require additional engineering and design to be implemented.
This recommendation was discussed with the Tetra Tech representative, and it is on their list of
improvement recommendations for the plant. It should be noted that implementation of this change may
take several years to complete.
Initial Recommendation
6. Consider installation ofa pH probe and/or inline alkalinity analyzer to control
the lime slurry feed rate to maintain proper pH and alkalinity in the activated
sludge process.
Status: Not implemented
During the site visit on July 17, 2023, it was observed that no additional automated monitoring of the raw
water or control for pH or Lime slurry feed had been installed. Staff continue collect a daily grab sample
for pH and make manual adjustments to the lime dosage rate as needed.
Lime is added for alkalinity control, primary for nitrification in the aeration process. An automated system
would ensure that the alkalinity in the raw water is optimal for this process. The current procedure of
adjusting the lime feed once per day does not optimize the alkalinity and does not allow for additional
(or less) alkalinity when needed specifically due to the fluctuation in loadings in the raw.
The current lime feed system is manually controllable. It would require some programming modifications
and the addition of a pH or alkalinity meter in the aerated grit chamber downstream from where the lime
slurry is being fed for controlling the increase or decrease in lime feed.
Initial Recommendation
7. Dissolved oxygen meters in the aeration basins should be calibrated at least
monthly to ensure proper air flow is delivered.
Status: Implemented
As of 17 July 2023, plant staff had increased the calibration of the dissolved oxygen meter calibration to
monthly.
Initial Recommendation
8. Consider implementing an industrial pretreatment program to manage
significant users and control peak loadings to the facility.
Status: Not implemented
During the site visit on July 17, 2023, we were informed that there was still no IPP program in place for the
significant user's contribution to the facility. We made this recommendation after evaluating data related
to the discharges from some of the breweries provided for the original evaluation report.
Discussion after the site visit with the Grand County Water and Sanitation District #1 staff indicated that
the different districts are aware that an IPP program is needed. Staff members understand this is a
management level task and will require additional evaluation and time to implement a program.
This recommendation would not be part of the normal responsibility of the wastewater treatment
operating staff; however, they should be included in the process and parameters that are set for the
significant users of the system.

August 11, 2023
Response to Upper Fraser Valley WWTP Evaluation Recommendations
The purpose of this technical memorandum is to provide review and response to the Upper Fraser Valley
WWTP Evaluation Recommendations and Follow -Up reports (report). The report provided eight
recommendations for operational improvements to the Upper Fraser Valley WWTP (WWTP). Responses to
those eight recommendations and Tetra Tech's subsequent recommendations are detailed below.
1) Repairs to the north aeration basin air header: The report recommends completing repairs to the north
aeration basin and concludes that the plant cannot handle peak loading with a single basin operation.
These repairs have been made.
Response: The report pays particular attention to the plant's ability to handle peak 30 -day average and 7 -
day average loads with both basins online. This is not in dispute. However, it is important to understand
that the WWTP has experienced permit violations over the last couple of years related to ammonia
treatment limitation. The plant's discharge permit (C00040142) requires varying ammonia limits on a 30 -
day average and a daily maximum basis, not a 7 -day average.
The December 2022 violation had a daily effluent maximum of 15.3 mg/L ammonia on 12/29/2023, more
than 3.0 mg/L over the permit limit of 12.0 mg/L. Sampling in the collection system on that same day
identified a 24 -hour composite sample ammonia concentration of 114 mg/L entering the plant. This is
nearly three times the average ammonia concentration that the plant typically receives. This extreme
condition indicates that the plan received an acute high strength load.
With both aeration basins operating, it is unlikely that the WWTP would be able to consistently treat high
strength ammonia conditions such as that seen on 12/29/2022. The growth rate of nitrifying bacteria is
significantly slower than that of the heterotrophic bacteria that consume BOD. As such, the WWTP could
not possibly maintain a high enough nitrifier inventory under normal conditions to accommodate acute
high strength ammonia events. If the WWTP intends to be able to effectively treat surprise high strength
ammonia loads, two options could be considered:
• Installation of an online ammonia probe and diversion of influent to for equalized treatment. This
approach would allow the plant to observe high strength influent and divert flow into the batch
decanter(BD) for leveled treatment. This option would require a significant investment in
infrastructure to divert and return flow and may require State approval and a potential permit
modification.
• Chemical addition of ammonia to support biological inventory: This approach would allow the
plant to maintain a high nitrifying biological inventory be supplementing ammonia load during
normal conditions. The high nitrifying inventory would then be able to absorb an acute loading
event. As an example, the brewery wastewater treatment plant at the Coors brewery in Golden, CO
operates a pure oxygen process that operates in this fashion in order to accommodate their

sporadic high strength ammonia loads. Chemical feed systems, chemical storage, online
ammonia monitory, permit modification, and State approval would be required for this option.
This process is not commonly used for municipal plants.
Neither of these options are recommended for implementation due to their unreasonable expense,
operational complexity, and regulatory complications, but are offered as options should high strength
loads not be addressed at their source. The most practical option for dealing with high strength ammonia
loads is to implement an industrial pretreatment program.
Recommendation: The plant's standard operational procedure is to operate both aeration basins, and
this should continue. However, the WWTP should retain assistance of a contractor to assist with large
scale maintenance operations, like the north aeration basin overhaul recently completed, to minimize
downtime and free plant staff to focus on operations.
2) Repairs to the south aerobic digester to minimize solids disposal and ensure class B sludge: The report
concludes that the WWTP must operate both digesters to maintain class B sludge and reduce dewatering
costs due to improved solids destruction.
Response: There is no guarantee that aerobic digestion will result in Class B pathogen compliance unless
enough degree-days of aerobic treatment are provided to meet EPA's default criteria for pathogen
compliance. In anaerobic and aerobic digesters, fecal coliform reduction is mostly a matter of die off and
about 90% reduction (1 log) can be expected. For example, to meet 900 -degree day requirement at 15°C,
the plant would need to digest solids for 60 days. In this respect, operation of the south digester would be
beneficial for maintaining Class B solids.
Solids destruction of waste activated sludge without primary sludge via aerobic digestion typically ranges
from 20% to 40%. Undigested waste activate sludge (WAS) can be more difficult to dewater because the
higher volatile solids content makes the sludge more hydrophilic. The WWTP, as well as most treatment
facilities in the country, utilizes polymer to assist in releasing bound water. Reduced volatile solids
destruction would require additional polymer usage, but the resulting cake solids should remain the
same. Hauling costs should remain the same, but polymer cost would increase.
For example, the Snake River WWTP in Summit County achieves in excess of 40% volatile solids
destruction and produces dewatered cake at between 18% and 20% solids content. The Frisco Sanitation
District WWTP achieves less volatile solids destruction due to the limited size of their digesters, yet their
dewater cake is produced at the same solids content as Snake River with a higher polymer dose.
Increased solids hauling appears to be the result of higher organic loading to the plant. Influent BOD
rarely exceeds 300 mg/L before 2020. For example, the highest recorded BOD in 2019 was approximately
330 mg/L. Since 2020, the WWTP has seen a steady increase of influent BOD, with composite samples
exceeding 700 mg/L. Overall average BOD does not appear to have increased significantly, but the acute
instances resulting from high loading events indicate that solids generation would go up significantly
during those instances.
Heterotrophic bacteria growth will trend with BOD loading, so high strength loads will increase mixed
liquor suspended solids concentration. Following the increased production of heterotrophic bacteria from
high strength loading events, plant staff is required to waste more activated sludge to maintain a healthy
aerobic solids retention time. As such, the increase in high strength loading events will result in more
solids wasting, which will result in increased solids hauling and disposal.
Recommendation: The report suggests purchase of a shelf spare motor to reduce downtime for the
mixer/sparged air aeration system. The WWTP plant has begun the process to acquire that motor.
However, the WWTP should consider replacing the sparged air/ mixer system with a diffused air system as
Page 214
TETRA TECH
Response to Upper Fraser Valley WWTP Evaluation Recommendations
8/11/2023
a future capital improvements project. The system currently operated by the WWTP may require up to
double the amount of power to operate when compared to a diffused air system. A coarse or fine bubble
system can be sized to provide solids suspension and aerobic digestion air demand, eliminating the need
for the mixer. The blowers already installed at the plant should be able to provide the air for a diffused
system. The Town of Berthoud, Colorado operated similarly design digesters to the those at the WWTP.
They replaced their sparged air/ mixer system with a fine bubble diffuser system and realized significant
power savings without sacrifice to digester performance.
3) Utilize the batch decanter to treat peak loads: The report recommends utilizing the BD as a backup for
peak load treatment when a basin is down for repairs.
Response: The report acknowledges that a significant investment in design and construction would be
required to make use out of the BD for aeration basin backup. If this were put into place, the BD should
not be continuously operated, and only used in times of long-term downtime for an aeration basin. During
these periods, operations staff would need to transfer activated sludge to the BD. Maintaining continuous
operation of the BD for the sole purpose of peak loading treatment would require unfeasible
supplemental carbon addition and would require up to a 30% increase in the plant's power consumption
for continuous aeration.
Recommendation: Investment of the scale needed to utilize the BD for backup operations would have
similar design costs to designing a third activated sludge train. Construction costs are likely much higher
for a new activated sludge train, but the plant would be left with a full capacity process instead of a half
capacity batch process. The WWTP and JFOC would be better served by a third aeration basin than
rehabbing the DB.
4) Consider installation of an inline COD analyzer to automatically divert peak loads. The report suggests
that an inline COD analyzer could be installed to automatically divert peak load influent to the BD.
Response: This approach would require a significant investment in operational and infrastructure
modifications to address a problem that can be solved through other means. The BD would need to be
completely overhauled to accept equalized flow, including addition of new conveyance lines and a new
pumping station. Automatic diversion to the BD would require improvements to the headworks facility to
provide automatic gates or valves to provide the flow diversion. In -line COD analyzers. Are known to be
difficult to maintain due to the digestion process required.
An alternative approach to an inline COD analyzer would be a more commonplace ammonia probe. Peak
BOD load and ammonia loads appear to correlate, so should the WWTP and JFOC decide to go the route of
load equalization, more easily maintained instrumentation is advised.
Recommendation: Automatic diversion will require a significant capital investment to address peak
loading events that should be eliminated by implementing an industrial pretreatment program.
5) Consider modifications to the secondary clarifier inlet chamber to facilitate both clarifiers when only one
aeration basin is in use. The report recommends adding flexibility to allow both clarifiers to be in
operation with only one aeration basin operating.
Response: The added flexibility of being able to operate both clarifiers with a single aeration basin online
would provide significant operational flexibility and treatment improvement. During peak load events, it
is likely that a single clarifier will not be able to handle the settling requirements of an overloaded basin.

Response to Upper FraserValley WWTP Evaluation Recommendations
8/11/2023
Two clarifiers in operation would greatly reduce the solids loading rate in this case, thereby reducing risk
of suspended solids passthrough. Providing flexible flow splitting would also allow for maintenance and
construction efficiencies in the future.
Recommendation: Consider including these modifications as part of the upcoming Project N.
6) Consider installation of a pH probe and/or inline alkalinity analyzer to control the lime slurry feed rate:
The report recommends installing a pH probe and/or inline alkalinity analyzer to control the lime slurry
feed rate to maintain proper pH and alkalinity in the activated sludge process.
Response and Recommendation: The addition of pH probe for chemical feed control is recommended to
optimize the lime system. However, future secondary improvements as part of Project N that include
optimized denitrification should reduce or eliminate the need for the lime system.
7) Dissolved oxygen meters in the aeration basins should be calibrated at least monthly to ensure proper air
flow is delivered.: This has been implemented.
8) Consider implementing an industrial pretreatment program to manage significant users and control peak
loadings to the facility: The report recommends implementing an industrial pretreatment program to
control peak load events.
Response and Recommendation: Tetra Tech has prepared a plan implement a pretreatment.

Industrial Pretreatment Program Development
and Implementation Recommendation
The Colorado Department of Public Health and Environment (CDPHE) Compliance Inspection Report for the Upper
Fraser Valley Wastewater Treatment Plant (WWTP), June 2023, notes that the implementation of industrial
pretreatment protections of the combined Joint Facilities Oversight Committee (JFOC) collection system and
WWTP had not occurred. The absence of pretreatment strategies has resulted in several noncompliance events
for the facility. The JFOC requested that Tetra Tech recommend a path forward for the development and
implementation of an Industrial Pretreatment Program (IPP or program).
PROGRAM INTRODUCTION
To mitigate future violations and assist the JFOC/WWTP in their responsibility to protect existing infrastructure
and the Fraser River water quality, Tetra Tech met with both CDPHE and EPA regarding the agencies'
expectations. This recommendation was developed based on the agencies' desired resolution to the June 2023
inspection report comment and research into other successful pretreatment programs with similar challenges.
CDPHE anticipates follow-up inspections of the facility to occur in 2026. Implementing this process well before the
2026 inspection can aid in preventing further violations and EPA enforcement action.
Section 7 (Industrial Waste Management) of the Colorado Discharge Permit (C00040142), issued to the Town of
Fraser, summarizes the responsibilities of the POTW (Upper Fraser Valley Wastewater Treatment Plant). To
mitigate the potential for additional noncompliance events caused by industrial discharges, it is recommended
that the JFOC/WWTP implement this pathway for pretreatment strategies using consistent communication and
documentation practices. A neutral, organized approach to program implementation and administration will
ensure its success.
This pathway is presented as three separate phases, with multiple objectives per phase, as a mutual effort
between the WWTP, JFOC, and IUs. The diagram below illustrates the pathway phases and the realistic approach
and timeline to addressing the impacts experienced by the lUs.

PHASE 1 OUTREACH AND DATA COLLECTION
Public Outreach and Education
Public outreach and education should be performed in collaboration with the industrial users (IU) throughout the
JFOC districts to better understand the IU's processes and effluent water quality. Public outreach should target
nonresidential lUs across the JFOC districts (including restaurants, automotive shops, manufacturing, health care,
breweries, distilleries, and other commercial and industrial dischargers). Information gathered will assist in
completing the remaining phases of program development and implementation. During outreach activities, the
IU's information on the environmental aspects and impacts of their processes to the WWTP and JFOC collection
system infrastructure should be available and discussed.
An in person visit to each industrial facility should be conducted with the intent to educate and build a
relationship on a common goal to protect the Fraser River and shared JFOC infrastructure. It will be important to
build a standing rapport with the IU, while communicating the concern for the future of the WWTP, meeting
current and future regulations, and potential issues that could arise from neglecting to establish and adhere to a
local pretreatment program. This program pathway may be presented at each visit to highlight the IU's role in its
development and success. Regularly scheduled follow-up visits are highly encouraged.
As far as breweries and distilleries are concerned, initial meetings have already occurred. However, monthly
follow-up educational meetings are recommended for the duration of Phase 1. Review of correspondence
following the initial meetings indicated that the lUs have a lack of understanding of their impacts to the WWTP.
Addressing the lUs understanding of impacts to the WWTP should be a priority for the JFOC, specifically that IU
discharge of solids is not the issue but rather high strength waste discharge is the issue. Cordial discussions with
expressed intent to collaboratively solve the issues at hand are crucial to build trust and a sense of ownership
with the lUs.
Water Quality Sampling and Process Review
Sampling of effluent water at each facility, preferably during a discharge event, should be coordinated either
during the initial visit, or at a follow-up visit. If this cannot be coordinated, a composite sampler can be placed in a
downstream manhole to collect a water quality sample over a set duration. Samples should be laboratory
analyzed for a minimum of total suspended solids (TSS), pH, biological oxygen demand (BOD), ammonia nitrogen,
and phosphorous.
Each IU's process, discharge practices, and ability to implement Best Management Practices (BMPs) should be
documented, noting preferences and limitations of the IU. Results from sampling and process review should be
collated and considered for the completion of the following phases.
PHASE 2: SOLUTION DEVELOPMENT
BMP Alternatives Analysis
After effluent water quality samples have been laboratory analyzed, and each IU's process has been documented,
an alternatives analysis should be completed in collaboration with the JFOC/WWTP to understand the beneficial
TETRA TECH
uses of captured effluent wastes from the lUs. BMPs should be selected that are functional for both the lUs and
the WWTP staff.
If beneficial capture and use within the treatment process is impractical for an IU, this analysis should aim to
identify alternative BMPs that are feasible in their unique applications, and resources or assistance to equip them
as necessary. Limitation and preferences of BMPS, identified during the process review, will be considered for
potential alternatives in managing effluent wastes.
Waste Collection and Beneficial Use Pilot
Beneficial use of captured wastes has been identified as a potential solution to the excess loading periodically
received at the WWTP for lUs producing brewery, winery, or distillery wastes. These potential dischargers are
identified on Figure 2, attached. These lUs predominately reside in the Grand County Water Sanitation District
and the Town of Fraser district limits.
A process should be developed for Ws that can implement a trial solution within their process immediately.
Waste can be collected at the discharger's location, hauled to the WWTP, and stored for use and application
within the wastewater treatment process at a time designated by WWTP operations staff. Logistics associated
with the pilot should be determined as the previous phases are completed. This pilot may require notifying and
coordinating with CDPHE for temporary process modification.
Collection Program and BMP Implementation
Results and recommendations developed from the BMP Alternatives Analysis and the Waste Collection and
Beneficial Use Pilot shall be implemented as part of the program's pretreatment strategies to reduce loading
challenges currently faced at the WWTP.
Development of Pretreatment Ordinances and Amendment of Municipal Code
To comply with state/federal regulations and maintain good standing of the discharge permit, to proactively
manage the industrial discharges received at the WWTP, and to avoid future EPA requirement of a formal
pretreatment program, the Town of Fraser Municipal Code should be amended to include a pretreatment
ordinance.
Pretreatment Ordinances should be drafted from the EPA Region 8 Example Ordinance for POTWs without
Approved Pretreatment Programs language and include the following:
o Reference State and National Pretreatment Standards and Requirements
o List authorities and rights of the JFOC/WWTP
■ Establish, clarify, and define Right of Entry and sampling rights of the JFOC/WWTP
■ Define Ills and who qualifies under the pretreatment ordinance.
■ Define IU statuses and requirements that can be issued to each user based on the quality
and quantity of their effluent discharge to the WWTP
o Define general standards and practices:
■ Define prohibited discharges.
TETRA TECH
• Optional: The requirement for establishing local limits for lUs based on the
maximum allowable headworks loadings (MAHLs) may be established as part of
the ordinance but will not be determined until outreach and stakeholder
collaboration has been conducted.
■ Define accidental slug discharges and hazardous waste discharges. Set protocol to be
followed by the IU in the event of these discharges.
■ Suggested and approved BMPs, as determined in the BMP Alternatives Analysis.
o Specify inspection and reporting requirements of lUs.
o Enforcement parameters -
■ Define inspection and sampling frequencies (performed and reported by the IU).
■ Administrative enforcement (warning plus additional sampling requirements/frequencies)
■ Administrative penalty (fines)
■ Legal enforcement, termination of service
Following the draft development of the Municipal Code amendment, legal review and acceptance from the Town
of Fraser, Grand County, and Winter Park Ranch entities should be conducted as indicated in the Rules and
Regulations of the Upper Fraser Valley Wastewater Treatment Agreement. Final ordinance and amendment of
the municipal code will be performed in collaboration with stakeholders from the JFOC and lUs and implemented
for the three JFOC Districts.
PHASE 3: RECORD KEEPING AND ADMINISTRATION
Recordkeeping and administration tasks shall be ongoing to ensure traction of the established and accepted
pretreatment ordinances and to assist the JFOC in the successful implementation and use of the installed BMPs.
These tasks are anticipated to include the following:
• Communicating and engaging with lUs
• Assisting IUs with implementing operational changes to adhere to the modified ordinance and usage of a
BMP capable of reducing excess wastewater loading.
• Full scale implementation of waste capture and beneficial use program
• Performing inspections, sampling, and managing follow-up recommendations to the lUs on adjustments
to their processes to maintain compliance with the updated ordinance.
• Support the IUs with required reporting (monthly, quarterly, annually as established in the Municipal Code
amendment).
• Executing enforcement actions as necessary in compliance with the accepted ordinance change.
o Consider adjustments to equivalent resident units (EQRs) held by each IU to match loading
contribution.
o Consider high strength surcharging with adequate notice.
