It’s purpose is to detail the functionality of the Non-Potable Irrigation system, and to provide general management practices during the irrigation season. The operation and maintenance of the system within the Metro District (referred to as the District) will be the responsibility of the District. The District will work to plan for future needs/improvements, mitigate drought impacts, and maximize efficient delivery of the water resources. In general, the Non-Potable Irrigation System uses irrigation water rights and existing groundwater wells to supply water for the system. The supply water is stored in ponds and then distributed to the users via pump stations within the development. A pictorial diagram of the system can be found in Appendix A and an overall system map can be found in Appendix B. 1.2 Management Responsibilities The District will oversee the management of water resources for all non-potable irrigated areas within the Montava Subdivision. These irrigated areas include all common area spaces (parkway strips, medians, etc.), District Managed Parks, City of Fort Collins Parks, and Poudre School District Facilities. It should be noted that Montava does not own the water rights for Fort Collins Parks or Poudre School District. Montava will have agreements with Fort Collins Parks and Poudre School District. These agreements will allow for all the irrigation water for Montava, Fort Collins Parks, and Poudre School District to be combined in the western non-pot pond and distributed through the District’s irrigation system accordingly. The maintenance of the system will be done by the District, however Fort Collins Parks and Poudre School District will assist in the funding for maintenance & operation through an agreed upon fee structure. Management of the Farm & Farm Pond at the northeast corner of the development will be on a separate irrigation system and is responsibility of a separate ownership entity. They will be responsible for all operations & maintenance of their irrigation system. The Farm system will not be connected to any of Montava’s Non-Pot System. 1.3 Water Rights Summary The water rights owned by the District for their non-potable irrigation system are sourced from groundwater wells located on the property, the Water Supply and Storage Company (WSSC), and from the North Poudre Irrigation Canal (NPIC). The water rights owned by the City of Fort Collins and Poudre School District are sourced from WSSC and from existing groundwater wells. Additional information regarding typical water rights terms and their associated definitions is provided in Appendix H.

Montava owns shares in both WSSC (Water Supply & Storage Company) and NPIC (North Poudre Irrigation Company) which will be conveyed to the Non-Potable Irrigation ponds located on within the subdivision. Montava also owns existing groundwater wells located throughout the project area, these wells will be used for Non-Potable irrigation as well via the Non-Pot Ponds. There are also two new wells to be located within the subdivision that will be used to fill the ponds initially and to offset non-irrigation season evaporation. Montava Subdivision Non-Pot Irrigation System Report Page 3 2.1.1 WSSC & NPIC Shares WSSC Shares The WSSC shares are to be conveyed to the West Pond via the Baker Lateral Irrigation line or other means if necessary. The Baker Lateral conveys WSSC irrigation water from the Larimer County Canal through a headgate located northwest of the intersection of Turnberry Rd. & Douglas Rd. Montava intends on accessing the Baker Lateral through an existing connection originally installed by Poudre School District. This connection is located at the southeast corner of Turnberry Rd. & Country Club Rd. The WSSC water will be conveyed through this connection to the West Pond. This connection is illustrated on the Non-Pot System Map (see Appendix B). Once conveyed to the West Pond, the WSSC water will be distributed for irrigation through the West Pump House. A flow control valve will be installed on this supply line as well to ensure that Montava does not exceed the flow rate it is entitled to under the combined shares (Montava, Fort Collins Parks, and PSD). The flow control valve will be connected to the District’s SCADA system (see Supply Metering below). NPIC Shares The NPIC shares will be conveyed to the East Pond via the NPIC #6 ditch that runs along the west side of Giddings Rd. The existing pipe will be extended through the project to deliver the supply water to the East Pond (see Appendix B). The NPIC extension will also include a supply line for the Farm Pond. The Farm & Farm Pond will not be connected to the Montava Distribution system and will be managed by a separate authority. This separate authority will be responsible for obtaining NPIC shares and for managing the supply & distribution system for the Farm property. A flow control valve will be installed on this supply line as well to ensure the Montava does not exceed its entitled flow rate. The flow control valve will be connected to the District’s SCADA system (see Supply Metering below). 2.1.2 Groundwater Wells The existing groundwater well are located throughout the project. The water from these wells is decreed for specific use areas (see Appendix C). Each well also has specific decreed and permitted flow rates and water use limits. The water from these wells will be pumped to the East & West ponds depending on the well’s location (east or west side of Giddings Rd). The place of use and flow rate for each well is decreed, therefore each well will need to be metered and its water distribution accounted for. The new groundwater wells for Montava will be used to fill the ponds and to offset evaporative losses during the non-irrigation season. The groundwater from the new wells is intended to stay in the ponds. 2.1.3 Water Mixing The salinity levels in the existing groundwater wells are too high for irrigation purposes. For this reason, a water mixing process will be used to dilute the salinity to acceptable levels. The well water will be mixed with either WSSC or NPIC water at approximately a 50/50 ratio over the course of the irrigation season. The water will be tested regularly to ensure that proper levels are maintained. 2.2 Ponds The Non-Pot irrigation supply system will deliver water to two separate ponds, one on the Montava Subdivision Non-Pot Irrigation System Report Page 4 West side of one on the East side (in general Giddings Rd. is considered the dividing line). Though the primary use of the ponds is for the non-pot system, they are intended to be an aesthetic feature of the development as well. Therefore, the ponds are sized accordingly to allow them to be drawn down while still maintaining their aesthetic function. The ponds will be constructed with a clay liner to prevent losses due to ground seepage. A memorandum, prepared by Kullman Water Engineering, LLC, provides the general accounting concepts that will be used for the non-potable ponds (see Appendix G). The west pond will be sized to include uses by both Fort Collins Parks & Poudre School District. The irrigation water owned by these other entities will be combined with Montava’s water supplies and distributed to the other entities’ parcels. These contributions will be accounted for during each irrigation season to ensure that each entity is receiving what they are entitled. The ponds will also be sized to allow for stormwater drainage. The pond volume will be increased to account for the additional stormwater above what is required for irrigation & aesthetics. An outlet structure will be located above the irrigation/aesthetics elevation. A flow meter will be placed on the outlet side of the outlet structure to measure stormwater flows. Each pond will be supplied by a combination of groundwater wells and irrigation water (WSSC and/or NPIC). As stated before, the new Montava wells will only be used to fill the ponds initially and offset evaporative losses during the non-irrigation season. Water from the existing wells will be mixed with the irrigation water (WSSC/NPIC) and distributed via pump station for irrigation uses during the irrigation season. Each pond will be equipped with a transducer to monitor water levels. These transducers will be connected to a SCADA system that will monitor and log the water elevations in the ponds. This will ensure the stormwater contributions to the ponds are managed as part of Montava’s water accounting. The Farm property that is located at the northeast corner of the development will be on its own delivery system (pond & pump station). However, the Farm Pond will share some of the supply connections. The Farm Pond will have access to the NPIC and the groundwater wells that are decreed for that location. 2.3 Supply System Metering The metering of all supply sources is vital to the water accounting for Montava. The WSSC & NPIC water sources will be metered to account for the amount of water supplied to each pond. Each groundwater well (both existing & new) will be metered at the well site through a belowground vault (see Appendix F). Since the groundwater wells will be pumped to the ponds, the total flow from the wells will be metered at each pond, to identify any leaks/losses in the supply system. The metering system will be part of an overall SCADA (Supervisory Control And Data Acquisition) system. This system will collect flow data from every meter for accounting purposes. The pumps and meters will be accessible by the District Manager at all time with the ability to evaluate and control in real-time. The flow readings will be logged and stored by the District for water accounting, system performance evaluations, and general records. Montava Subdivision Non-Pot Irrigation System Report Page 5 3.0 Irrigation Delivery 3.1 Water Delivery System The delivery system for Montava’s Non-Pot system,not including the Farm Pond, is divided into two separate networks, east & west. As discussed previously, there are two ponds that will be used as the collection points for all non-pot irrigation water. Each pond will have inflows from the supply sources and a pump station to filter & deliver the irrigation water to the users. The two systems are designed to operate independently. However, an emergency bypass connection will be provided between the system to provide flexibility in the event water would need to be moved between the networks. Outside of an emergency situation, the bypass connection will remain closed. As stated before, the Farm at the northeast corner of the development will have its own pond, pump station, and delivery system. The Farm’s delivery system will not be connected to Montava’s system and therefore it not part of the District. Operations & maintenance of the Farm’s system will be the responsibility of the controlling entity. 3.2 Delivery System Criteria The following assumptions were used to design the system: West System Minimum Pressure at Lots – 60 psi Minimum Pressure at Open Space – 80 psi Demand Per Lot – 6 gpm System Demand – 5610 gpm Watering Schedule – 3 ea. 4 hr. blocks (12 hr. window) with a 8 hr. window for open space East System Minimum Pressure at Lots – 60 psi Minimum Pressure at Open Space – 80 psi Demand Per Lot – 6 gpm System Demand – 5610 gpm Watering Schedule – 3 ea. 4 hr. blocks (12 hr. window) with a 8 hr. window for open space 3.3 Pump Stations There are a total of two pump stations that will supply non-potable irrigation water for Montava. Each pump station is located at one of the non-pot irrigation supply ponds (East and West). The pump stations have a filtered intake from the ponds to a wet-well. From the wet-well the water will be filtered again and a series of pumps will be used to charge the non- pot system and deliver irrigation water to all the users. Please see Appendix D for example details of the pump stations and self-cleaning filters. Each pump station will be connected to the SCADA system for the District. Within each pump station will be a control center where all pumps & metering for both East & West systems can be accessed. The WSSC & NPIC supply meters and the pumps & meters for the groundwater Montava Subdivision Non-Pot Irrigation System Report Page 6 wells will also be accessible through the control centers. 3.4 Delivery System Metering The metering at all delivery points is the other vital requirement for water accounting for Montava. Each pump station will be meter at the outflow pipe. From there, each point of connection (residential lots, Multifamily irrigation, commercial irrigation, open space, parks, etc.) will receive a meter (see Appendix F proposed meters). Again, all meters will be connected to the SCADA system. This will ensure accurate water accounting, as well as provide evidence of water losses or inefficiencies. 4.0 SCADA System The SCADA system for Montava is intended to be extensive with some level of redundancy to maximize the accuracy of the water accounting. The system will control & monitor all supplies & deliveries throughout the system. Control of the pump stations will also be available through the SCADA system. The District Manager will receive alerts for any issues in the system so they can dispatch maintenance crews. 4.1 Inflow Monitoring As stated above, all inflows (WSSC, NPIC, groundwater wells, etc) will be metered and controlled with flow control valves. Each source of water has a decreed flow rate which will be monitored and adjusted as needed (see Appendix B the Non-Pot Map & Appendix F for typical flow meters & valves). The following inflows will be monitored: - WSSC & NPIC o Metered at ponds; may also require measurement at the farm headgate per ditch company policies o Flow control valves - Existing Groundwater Wells o Metered at each well o Metered at the combined pond supply point - New Groundwater Wells o Metered at each well - Stormwater o This will be metered through the use of a water level transducer. The water levels will be recorded and used to determine pond levels before and after a storm. Since all other inflows (WSSC, NPIC, Groundwater wells) and outflows (from pump station) are metered, the volume of storm water can be determined. 4.2 Outflow Monitoring As stated above, all POC (Points of Connection) will be metered. The delivery rates/volumes for each groundwater well, and their decreed area of use, will be monitored and checked against the inflows and volumes used at POCs to make sure the water accounting balances (see Appendix F for typical flow meters & valves). The following outflows will be monitored: - Residential Irrigation Tap o One tap per lot Montava Subdivision Non-Pot Irrigation System Report Page 7 - Multi-Family Irrigation Tap o One tap per complex - Commercial/Mixed-Use Taps o One tap per complex - Open Space & Parks o Multiple District taps o Individual taps for Fort Collins Parks & PSD - Pump Station Outlet o This will be a large flow meter at the outlet pipe of the pump station. This meter will be used to check against the combined totals of all the other meters and to compute a daily mass balance on the pond(s). - Stormwater o Metered at the outlet of the stormwater outlet structure. 5.0 System Operations 5.1 Schedule of Operations Operations for the District’s water supply undergo an annual pattern based on water rights limitations, demands, and streamflow conditions. This section provides an overview of the primary goals of operations during various stages of the year and also provides clear tasks which must be accomplished within the defined stages. End of March The end of March requires preparation for upcoming irrigation season operations, which vary significantly from winter operations. Tasks to prepare for irrigation season operations and meet demands in March include: Clear debris from all well filters, headgates, and turnouts. Check all major metering devices (supply meters, pump station meter, etc.) to ensure such devices have not been tampered with and are reporting proper values to the SCADA system. Confirm lake level transducers are reporting proper values to SCADA system and calibrate if needed. Communicate with WSSC & NPIC to determine when the ditches will be turned on. Confirm that accounting is set up to accommodate expected operations during irrigation season Determine the District’s drought status (to be determined through Districts’ water engineers, currently Kullman Water Engineering, LLC) and make water use restriction recommendations for upcoming irrigation season. Submit monthly accounting to Division of Water Resources. Top off ponds as required with new Montava groundwater wells. April April marks the beginning of irrigation season throughout the Front Range. In general, it is important to ensure that all measurement systems are functional, the accounting can accommodate irrigation season operations, and communication has been established with the water commissioner, Ditch riders, the City of Fort Collins, and other relevant entities. Notable tasks that are essential to April operations include: Montava Subdivision Non-Pot Irrigation System Report Page 8 Prepare non-potable system for irrigation season, Communicate with residents regarding irrigation restrictions, Use groundwater wells to satisfy any early irrigation needs, if surface water is available Divert WSSC or NPIC water as necessary and available to mix with groundwater wells, and Submit monthly accounting to Division of Water Resources. May (Additional May recommendations in May through September) Recommended tasks for May include: Begin operation of the groundwater wells, Begin taking WSSC & NPIC water and mixing with groundwater well supplies, Submit monthly accounting to Division of Water Resources. May through September (Additional September recommendations in September) During the core irrigation season months of May through September, the goal of operations is to ensure that ponds remain full with minor fluctuations as irrigation water is used and replenished. These goals can be achieved by completing the following tasks: Enforce irrigation restrictions and monitor for non-potable system leaks, Monitor WSSC & NPIC flows based on entitlements and availability, Monitor groundwater well flows, volumes and place of use against water rights limits, Submit monthly accounting to Division of Water Resources. September September marks a time in which irrigation demands and water supplies should begin ramping down for the year. The following tasks are recommended for September: Monitor WSSC & NPIC flows based on entitlements and availability, Monitor groundwater well flows, volumes and place of use against water rights limits, Submit monthly accounting to Division of Water Resources. October October generally represents the last month of irrigation season throughout the Front Range. October has similar challenges as those described for the month of April: there is still irrigation demand across the District but there are very limited amounts of water supply available under the Districts' ditch shares. Due to limited supplies, it is important to minimize customer demands as much as possible. The wells can be used in these situation, but water quality can be a concern. During this time frame surface water will be prioritized when it is available. It is important that the following take place in October: Winterize flow meters and other equipment as necessary, Winterize non-potable system, Top off ponds as required with new Montava groundwater wells, Submit monthly accounting to Division of Water Resources, and Prepare a new water accounting sheet for data beginning November 1st and ensure SCADA systems are adjusted to automatically enter data. Montava Subdivision Non-Pot Irrigation System Report Page 9 November through March (Winter Operations) It is important to note that although the District generally stops irrigation in October, there are typically small amounts of water delivered for irrigation to residential areas in November. These November water uses should be minimized as much as possible. During the winter, the primary goals of operations are to keep the irrigation ponds full through the use of the new groundwater wells. To achieve these goals, the following tasks are recommended: Submit monthly accounting to Division of Water Resources, Monitor pond levels and use the new groundwater wells to fill as necessary, Entirely shut off non-potable system irrigation deliveries as soon as possible, Strategize with water engineers and operations managers whether any changes to supplies are needed for next irrigation season and begin efforts to address changes, This annual schedule highlights key tasks throughout the year to ensure efficient management of the District’s water supplies. 6.0 Best Management Practices Strategic use of water rights helps maximize beneficial uses of the water, supports a steady and reliable supply of water to the District’s customers, ensures adequate water quality and reduces the impacts of drought. This section of the report aims to describe some of the best management practices (BMPs) the District can adopt to optimize its use of existing water rights. While other sections of this report delineate specific tasks to undertake at different points in the year to enact these BMPs, this section serves as a broader explanation of why these practices are effective, and why these practices are valuable for the Districts. Structure Maintenance Regular and diligent maintenance of the various structures used to divert and distribute water is also key to reducing wasted water. It is recommended that the Districts regularly inspect all aspects of their water delivery and distribution system, including: monitoring for pipe leaks; regularly checking that channels are clear of debris and allow water to flow through efficiently; and maintaining diversion structures to ensure efficient and accurate delivery of water. Regular maintenance of the pump stations and groundwater vaults is also recommended. Demand Management Even with mindful management of water rights and maintaining the water delivery and storage system, it is likely that there will be years where available water supplies are less than the District’s demand (i.e. drought or increased regional demand). Having a drought management plan with multiple stages tied to drought intensity to reduced water use is paramount for weathering such scenarios. The District should have a Drought Plan developed once the system is understood. Fully utilized drought management plans are a very effective tool in helping communities weather water scarcity scenarios with minimum long-term impacts. Any reductions in water demands, whether achieved through watering restrictions or efficient water use helps increase the District’s ability to withstand droughts. Montava Subdivision Non-Pot Irrigation System Report Page 10 Maintenance of Functional Accounting The Districts should also maintain accurate water accounting. If the State requests accounting forms or an audit, responding quickly and showing good faith helps to maintain a good relationship and goodwill throughout the process. Maintaining accounting is a requirement associated with the Districts’ water rights, and failing to comply either with the accounting itself or with a requested accounting audit could prevent the Districts from diverting additional water. 7.0 Budgeting Evaluation It is important for the District to have an understanding of anticipated irrigation demands in order to evaluate system losses or over watering issues. Therefore, it is recommended that the District develop a “Water Budget”. This would allow the District to focus on analyzing single- family, multi-family, commercial, and common areas. The anticipated irrigation demands can be correlated to the individual uses and relayed to residents, property managers, maintenance crews, etc. Once in place, the Water Budget will be an important tool in communicating with the residents. Providing them with all the information they need to manage their properties and understanding the effects on their community. The information will also allow the districts to evaluate common area landscaping demands and adjust over time. The Water Budget will evolve as the development grows. As each phase is built out, a budget for each phase can be developed. This information is then incorporated into the overall water budget which will allow the District to forecast water need more accurately. 8.0 Conclusion In conclusion, the Montava subdivision is well positioned to create a robust, efficient, and accurate Non-Pot Irrigation System. The system will be able to monitor and log all supply and delivery flows for accurate accounting. Through the use a SCADA system, the District can monitor everything in real time, thus reducing response times to maintenance issues. The system will also provide all users with access to their meters, which promotes transparency and accountability for all parties involved.

Based on Faraday’s law of induction, these meters can measure water, wastewater, water-based fluids and other liquids that meet minimum electrical conductivity. Designed, developed and manufactured under strict quality standards, this meter features sophisticated, processor-based signal conversion with accuracies of ±0.20% of rate ±1 mm/s. The wide selection of liner and electrode materials helps provide maximum compatibility and minimum maintenance over a long operating period. The meter is best suited for bidirectional flow measurement of fluids with a conductivity > 5 µS/cm (> 20 µS/cm for demineralized water). The meter has high accuracy, is easy to use, and can be chosen for a wide variety of applications. The backlit, four-line display shows all actual flow measuring data, daily and complete information, including alarm messages. The standard transmitter has 4 programmable digital outputs, one digital input, power output and different interfaces. Integrated system self checkup makes putting into operation and service easier. For service purpose, the meter configuration can be kept or transferred to another meter without a new parametering via the optional back-up parameter function. APPLICATION The M2000 transmitter can be integrally mounted to the sensor or can be remote-mounted, if necessary and has many advantages over other conventional technologies. The meter targets a variety of applications and is well suited for the diverse water and wastewater treatment industry. The M2000 meter can accurately measure fluid flow—whether the fluid is water or a highly corrosive liquid, very viscous, contains a moderate amount of solids, or requires special handling. Today, electromagnetic meters are successfully used in industries including building automation, oil and gas, food and beverage, pharmaceutical, water and wastewater, and chemical. STRAIGHT PIPE REQUIREMENTS Run sufficient straight-pipe at the sensor inlet and outlet for optimum meter accuracy and performance. An equivalent of 3…7 diameters of straight pipe is required on the inlet (upstream) side to provide a stable flow profile. Two (2) diameters are required on the outlet (downstream) side. In applications with limited space, the M2000 can be installed with zero straight pipe requirements and fulfils the accuracy according OIML R49 and MID Annex MI-001.

M2000 electromagnetic meters have an “empty pipe detection” feature. This is accomplished with a third electrode positioned in the meter at twelve o’clock. If this electrode is not covered by fluid for a minimum five-second duration, the meter displays an “empty pipe detection” condition, sends out an error message, if desired, and stops measuring to maintain accuracy. When the electrode again becomes covered with fluid, the error message disappears and the meter resumes measuring. As an option to using grounding rings, a grounding electrode (fourth electrode) can be built into the meter during manufacturing to assure proper grounding. The position of this electrode is at six o’clock. OPERATION The flow meter is a stainless steel tube lined with a non-conductive material. Outside the tube, two DC powered electromagnetic coils are positioned opposing each other. Perpendicular to these coils, two electrodes are inserted into the flow tube. Energized coils create a magnetic field across the whole diameter of the pipe. As a conductive fluid flows through the magnetic field, a voltage is induced across the electrodes. This voltage is proportional to the average flow velocity of the fluid and is measured by the two electrodes. The M2000 transmitter receives the sensor’s analog signal, amplifies that signal and converts it into digital information. At the processor level, the signal is analyzed through a series of sophisticated software algorithms. After separating the signal from electrical noise, it is converted into both analog and digital signals that are used to display rate of flow and totalization. With no moving parts in the flow stream, there is no pressure lost. Also, accuracy is not affected by temperature, pressure, viscosity or density and there is practically no maintenance required.

Meters are available for residential, commercial and industrial services where flow is in one direction only. The meter and its internal components are for use in the measurement of non-potable water only. Caution must be exercised not to mingle non-potable and potable water meters and especially their internal components. Utility Impacts Utilities faced with rising water costs and limited water resources are developing non-potable, reclaimed water distribution systems. Accurate, dependable metering is needed to bill customers for these alternate supplies. Special coloring and markings are designed to distinguish potable water meters from reclaimed water meters in accordance with current industry standards. The utility must develop appropriate operational procedures to ensure that potable water meters and reclaimed water meters and their internal components are not mingled. Warranty Due to the lack of a uniform definition of the composition of reclaimed water, the warranties associated with reclaimed water meters are different than the potable water Recordall meter line. Please review the warranty statement for this important difference.

Date: April 23, 2022 Re: Accounting Concepts for Montava Non-potable Irrigation Ponds In this memorandum I include an overview of the various accounting concepts that will be required for non-potable irrigation ponds at Montava, including the West Pond, East Pond and the Farm Pond. Pond Inflows • Sources of potential inflow for West Pond only: o WSSC shares (potentially from both Montava and Fort Collins) o Groundwater from existing Montava wells (including one Portner well) o Groundwater from existing Fort Collins wells (including one Portner well) o Groundwater from proposed new Montava well o The pond should be constructed so as to prevent long-term retention of stormwater inflows. o The planned clay liner will prevent groundwater seepage inflows • Sources of potential inflow for East Pond only: o NPIC shares (potentially from both Montava and other entities) o WSSC shares (potentially from both Montava and other entities) o Groundwater from existing Montava wells o Groundwater from proposed new Montava well o The pond should be constructed so as to prevent long-term retention of stormwater inflows. o The planned clay liner will prevent groundwater seepage inflows • Sources of potential inflow for Farm Pond only: o NPIC shares o WSSC shares o Groundwater from existing Montava wells o The pond should be constructed so as to prevent long-term retention of stormwater inflows. o The planned clay liner will prevent groundwater seepage inflows • All sources of inflow should be measured at least on a daily basis before delivery to the pond(s). 2 Phone : 505-690-1432 I Email : rachel@kullmanwater.com I Web : www.kullmanwater.com Address: P.O. Box 5464 Santa Fe, NM 87502 o Each well will need to be measured independently as water is pumped from the aquifer (it may not be necessary, from a water rights perspective, to measure each well separately as delivered into the pond(s), if piped from the wellhead). o WSSC and NPIC deliveries to the pond(s) (or property if piped to pond(s)) will need to be measured. It may not be necessary to separately measure deliveries by entity in the case of the West and East Pond, if simultaneous deliveries can be prorated. Pond Outflows • Sources of potential outflow for West Pond only: o Fort Collins’ irrigation uses under the various water sources: WSSC shares, groundwater from Montava’s existing groundwater wells or Fort Collins’ existing groundwater well. o Montava’s irrigation uses under the various water sources: WSSC shares, groundwater from Montava’s existing groundwater wells o Groundwater from the new Montava well will be used to fill the pond initially and to offset evaporation losses during the non-irrigation season. Groundwater from the new well is not planned to be released from the pond. o Evaporation losses Evaporation losses will be calculated using unit daily evaporation rates and the amount of surface water exposed in the pond on a daily basis. The surface area will be determined from a staff gage placed in the pond and an associated stage-area curve/chart. Evaporation losses will be calculated during the irrigation season and non-irrigation season on a daily basis. Irrigation season losses will be deducted from the various water source accounts held in the pond, likely on a pro-rata basis. Non-irrigation season losses will be deducted from the stored groundwater pumped from Montava’s new well. o The proposed clay liner will prevent groundwater seepage outflows • Sources of potential outflow for East Pond only: o Montava’s irrigation uses (and other entity uses, if applicable) under the various water sources: NPIC shares, WSSC shares, groundwater from Montava’s existing groundwater wells o Groundwater from the new Montava well will be used to fill the pond initially and to offset evaporation losses during the non-irrigation season. Groundwater from the new well is not planned to be released from the pond. o Evaporation losses Evaporation losses will be calculated using unit daily evaporation rates and the amount of surface water exposed in the pond on a daily basis. The surface area will be determined from a staff gage placed in the pond and an associated stage-area curve/chart.

Box 5464 Santa Fe, NM 87502 on a pro-rata basis. Non-irrigation season losses will be deducted from the stored groundwater pumped from Montava’s new well. o The proposed clay liner will prevent groundwater seepage outflows • Sources of potential outflow for Farm Pond only: o Montava’s irrigation uses under the various water sources: NPIC shares, WSSC shares, groundwater from Montava’s existing groundwater wells o Evaporation losses Evaporation losses will be calculated using unit daily evaporation rates and the amount of surface water exposed in the pond on a daily basis. The surface area will be determined from a staff gage placed in the pond and an associated stage-area curve/chart. Evaporation losses will be calculated during the irrigation season and non-irrigation season on a daily basis. Irrigation season losses will be deducted from the various water source accounts held in the pond, likely on a pro-rata basis. Non-irrigation season losses will not occur because the Farm Pond is anticipated to be empty during the non-irrigation season. o The proposed clay liner will prevent groundwater seepage outflows • All sources of outflow should be measured at least on a daily basis as released from the pond(s). o At a minimum, Fort Collins’ total irrigation uses/outflows and Montava’s total irrigation uses/outflows should be measured in the case of the West Pond. o At a minimum, any other entity’s total irrigation uses/outflows (if applicable) and Montava’s total irrigation uses/outflows should be measured in the case of the East Pond. o At a minimum, Montava’s total irrigation uses/outflows should be measured in the case of the Farm Pond. o Use of water from Montava’s existing groundwater wells (and Fort Collins’ well for the West Pond) are restricted to particular locations by permit and decree and it will be necessary to ensure compliance with these limitations to the extent such sources are used on the irrigated areas. It may be necessary to meter groundwater distribution at strategic locations in the non-potable system in order to quantify and account for these limitations or otherwise measure at points of end use. o NPIC shares cannot be used for irrigation west of Giddings Road. When developing the accounting for the East Pond and Farm Pond, this limitation should be tracked. o For the West Pond, once irrigated areas for each entity are determined/finalized, it may be necessary to include additional measurement points as water is distributed for irrigation in order to accurately account for each entity’s share of the groundwater and the WSSC shares. 4 Phone : 505-690-1432 I Email : rachel@kullmanwater.com I Web : www.kullmanwater.com Address: P.O. Box 5464 Santa Fe, NM 87502 Storage Accounts • For the West Pond, it will be necessary to account for the amount of water stored in the pond on a daily basis by entity (i.e. Montava vs. Fort Collins), for all sources of water (i.e. “colors”). • For the East Pond, it will be necessary to account for the amount of water stored in the pond on a daily basis by entity (i.e. Montava vs. other entity, if applicable), for all sources of water (i.e. “colors”). • For the Farm Pond, it will be necessary to account for the amount of water stored in the pond on a daily basis for all sources of water (i.e. “colors”). • In order to quantify the amount of water stored for each entity/color account, it will be necessary to parse out inflows and outflows into the appropriate accounts. The methodology used to complete this parsing of sources will be based on various criteria and limitations associated with both the sources and uses of water (some of which are described in the next section). Limitations on Use of Water • WSSC and NPIC shares: o Share deliveries should not be stored in the pond(s) more than 72 hours because the shares will not be decreed for storage purposes in the ponds. o Share deliveries should not be made on lands that are not within the historical service area of the ditch system, unless specific approval is granted otherwise. • Montava’s and Fort Collins’ existing groundwater wells: o Groundwater from these wells should not be stored in the pond(s) more than 72 hours because the groundwater is not decreed for storage purposes in the pond(s). o Each groundwater well will have limitations or restrictions by decree and permit that will need to be considered and monitored, including: Decreed/permitted flow rate Decreed/permitted place of use Decreed/permitted annual volumetric limit Augmented annual volumetric limit (if different from decree/permit) o As previously mentioned, it will be necessary to track/account for groundwater use from these wells to the point of application at the various irrigation sites in order to demonstrate compliance. Additional measurement may be necessary in order to comply. • Montava’s new groundwater wells: o Use of groundwater from these well(s) will allow Montava to keep the pond full during the non-irrigation season. 5 Phone : 505-690-1432 I Email : rachel@kullmanwater.com I Web : www.kullmanwater.com Address: P.O. Box 5464 Santa Fe, NM 87502 o The limitation on use from these well(s) will be permitted uses and volumetric amounts determined under the new augmentation plan decree or substitute water supply plan. Figures 1 through 3 include schematics of the West Pond, East Pond and Farm Pond, respectively. Table 1 includes water rights information associated with Montava’s existing groundwater wells, as well as Fort Collins’ Portner Well.
