Baylosis, PE. The OWTS is designed to serve a four bedroom single family residence and one bedroom ADU for a total design flow based on five bedrooms. The design was revised and will use the existing 1500 gallon tank(#IS1705-97). The OWTS consists connecting the sewer lines from the main house and the ADU at a "wye" to the existing 1,500 gallon two compartment septic tank. Repair to the existing inlet tee and installation of an effluent filter in the outlet tee must be made. Effluent will then gravity flow through schedule 40 effluent line to a 500 gallon single compartment Valley Precast pump chamber with an Orenco PF3005 pump within a Orenco Biotube Pump ProPak. Set the pump floats to dose 80 gallons, before drainback, approximately 122 feet to an Orenco automatic distribution valve (ADV), placed at the high point of the system and made accessible at grade in an insulated riser. The ADV will alternate pressure dosed effluent between two sections of the over-excavated sand filter bed, 12 feet by 71 feet, to be replaced with three feet deep of secondary sand filter media. Install laterals, distribution orifices, and flushing assemblies as shown on the engineered design. NOTES: Gradation of the sand media use must be completed within one month prior to the installation and confirmed with the design engineer. If the sand does not conform to secondary or preferred sand media requirements, it cannot be used for the sand treatment media. Written approval from the gas company must be obtained to cross the utility easement prior to beginning construction. The sewer line must be encased, as described in table 7-1 footnote 2 or other method of equal protection, for 50 feet on either side where it crosses the irrigation ditch easement. Contact Eagle County Environmental Health and the design engineer well in advance of requesting inspections prior to backfilling any component of the OWTS. The design engineer is responsible for conducting all inspections necessary to certify the installation and assure the functionality of the system. System certification, along with photos and a record drawing is required to be submitted to and approved by Eagle County Environmental Health prior to the use of the system or occupancy of the dwelling.

The Onsite Wastewater Treatment System (OWTS) was designed and installed to serve the five-bedroom residence and one bedroom ADU on the above property. Additional information about the maintenance of your septic system needs can be accessed through our website links, provided on the Environmental Health Department’s septic system resource page. Be aware that changes in the use of your property or alterations of your building may require commensurate changes to, or relocation of, your septic system. Landscape features, trees with taproots, irrigation systems, and parking areas above the soil treatment area can cause a premature system failure. It is equally important that you notice and immediately repair dripping faucets and hissing toilets as this will certainly cause the system to fail. If you have any questions regarding this information, please contact us at (970) 328-8755 and reference the OWTS septic permit number.

Savage Excavation installed the system. The OWTS design is based on 4-bedrooms in the main house and 1-bedroom in the accessory dwelling unit (ADU). An average daily wastewater flow of 675 GPD was used. The existing 1500-gallon, two-compartment poly septic tank remained in use (at the request of the owner and contractor) and was connected to both the main residence and ADU. The inlet tee was repaired, and an effluent filter installed on the outlet tee. This filter must be cleaned annually, or as needed. A new, 4-inch diameter Schedule 40 sewer line crossed the top of the culvert. The sewer line was encased at least 10-feet on each side of the ditch. A new 500-gallon, single-compartment concrete Valley Precast pump chamber with an Orenco® Biotube Pump Vault and an Orenco® PF3005 pump was installed. The floats were set to dose approximately 80 gallons each pump cycle, allowing approximately 13 gallons of drain back after each pump cycle. Valley Precast performed start up of the pumping system on August 31, 2022. Effluent is pressure dosed through a 1.5-inch diameter pump line from the pump chamber to an Orenco® automatic distributing valve (ADV), model 6402. The ADV was placed at a high point in an insulated riser with access from grade. Effluent is pressure dosed through 1.5-inch diameter distribution lines to an over-excavated, 12’ x 71’ unlined sand filter, split into two zones. A minimum of 3-feet of sand filter material was installed in the over- excavated footprint. A gradation of the sand media is enclosed. Laterals used to disperse the effluent were surrounded by washed coarse screened gravel. Laterals were 1.5-inches in diameter with 5/32-inch diameter orifices facing down, spaced 3-feet on center (OC). Orenco® Orifice Shields were installed on the laterals at each orifice. Laterals began 2-feet from the edges of the sand filter, with 4-feet between each lateral. Each 1.5-inch diameter lateral ends in a sweeping ell facing up with a ball valve for flushing. A soil separation fabric was placed over the gravel layer followed by topsoil to support vegetative growth. 8-31-2022 The OWTS was generally installed according to specifications. This observation is not a guarantee of workmanship and/or parts and materials. CBO Inc. should be notified if changes are made to the OWTS in the future. Any additional OWTS construction must be according to the county regulations. LIMITS: Observations are limited to components that are visible at the time of the inspection. The installer must have documented and demonstrated knowledge of the requirements and regulations of the county in which they are working. The quality of the installation is dependent on the expertise of the installer, soil type, and weather conditions. Please call with questions. Sincerely, CBO Inc.

Using a Pump Curve A pump curve helps you determine the best pump for your system. Pump curves show the relationship between flow (gpm or L/sec) and pressure (total dynamic head, or TDH), providing a graphical representation of a pump’s optimal performance range. Pumps perform best at their nominal flow rate — the value, measured in gpm, expressed by the first two numerals in an Orenco pump nomenclature. The graphs in this section show optimal pump operation ranges with a solid line. Flow flow rates outside of these ranges are shown with a dashed line. For the most accurate pump specification, use Orenco’s PumpSelect™ software.

These zones can be segments of sand filter manifolds, drainfields, or other effluent distribution systems. Distributing valve assemblies can substantially simplify the design and installation of a distribution sys- tem and reduce installation costs. This is particularly true where a distributing valve assem- bly is used instead of multiple pumps and/or electrically operated valves. Additionally, a reduction in long term operation and maintenance costs is realized due to a reduced size and/or number of pumps. More even distribution can be achieved on sloping sites by zoning laterals at equal elevations. This eliminates drainback to lower lines and the unequal distrib- ution of effluent that occurs at the beginning of a cycle. Valve Operation The valve itself has only a few moving parts, requires no electricity, and alternates automati- cally each cycle. Refer to Figure 1 for the following valve operation description. The flow of the incoming effluent forces the rubber flap disk 1 to seat against the valve bottom 2. The opening 3 in the rubber flap disk aligns with an opening in the valve bottom to allow flow to only one valve outlet. The stem 4 houses a stainless steel spring which pushes the rubber flap disk away from the valve bottom after the flow of effluent stops. The stem acts as a cam follower and rotates the rubber flap disk as the stem is raised and lowered through the cam 5. The force from the flow of effluent pushes the stem down through the cam and the stainless steel spring pushes the stem back up through the cam when the flow of effluent stops. Each linear motion of the stem allows the rubber flap disk to rotate half the distance necessary to reach the next outlet. When there is no flow, the rubber flap disk is in the “up” position and is not seated against the valve bottom. 5 4 3 2 1 Inlet Outlets Figure 1: 6000 Series Valve Orenco Automatic Distributing Valve Assemblies NTP-VA-1 Rev. 1.2, © 11/03 Orenco Systems®, Inc.

FOR CURRENT DESIGN CRITERIA, call Orenco Systems, Inc. at 1-800-348-9843. The Distributing Valve Assembly The Orenco Automatic Distributing Valve Assembly combines the distributing valve itself and sever- al other components to give a complete preassembled unit that is easy to install, monitor, and main- tain. Figure 2 shows a complete assembly. Because distributing valves with several outlets can be difficult to line up and glue together in the field, the discharge lines in the assemblies are glued in place at Orenco. The unions (1) allow removal and maintenance of the valve. The clear PVC pipe sections (2) give a visual check of which discharge line is being pressurized. The inlet ball valve (3) allows a quick, simple method to test for proper valve cycling. The ball valve also stops the flow of effluent in case the pump is activated unexpectedly during maintenance or inspection. Check valves may be necessary on the discharge lines. Use of check valves is discussed in the valve positioning section. Valve Assembly Hydraulics Liquid flowing through the valve assembly must pass through fairly small openings and make several changes in direction. Because of this, headlosses through the valve assembly are fairly high. Table 1 gives the headloss equations for several different assemblies and Figure 3 shows the graphical repre- sentations of these equations. Orenco recommends that high-head turbine pumps be used to pressur- ize the valve assemblies to ensure enough head is available for proper system operation. High-head turbine pumps are also recommended because the use of a distributing valve usually requires more frequent pump cycling. The high-head turbine pumps are designed for high cycling systems and will outlast conventional effluent pumps by a factor of 10 or more in a high cycling mode. Furthermore, the high-head turbine pump intake is 12 inches or more above the bottom of the pump and tends to prevent any settled solids from being pumped into the distribution valve and obstructing its opera- tion. A minimum flow rate through the distributing valve is required to ensure proper seating of the rubber flap disk. Minimum flow rates for the various models are given in Table 1.

However, because of the mechanical movements of the valve, it is necessary to take steps to prevent solids from reaching the distributing valve that may impede the operation of the valve. Orenco Biotube®Pump Vaults — when properly sized and installed — provide the necessary protection to prevent valve malfunction. The Biotube®pump vault accepts effluent only from the clear zone between a tank’s scum and sludge layers and then filters this effluent through a very large surface area screen cartridge. Without this protection in effluent systems, the valve has very little chance of reliable long-term operation. Figure 3: Automatic distributing valve assembly headloss curves Valve Positioning The physical position of the valve in relation to the pump and the discharge point is very important for proper valve operation. The most reliable operation occurs when the valve is placed at the high point in the system and as close to the pump as possible. The transport line between the pump and valve should be kept full if possible. If the line is empty at the beginning of each cycle, pockets of air during filling can cause random rotation of the valve. The valve is particularly vulnerable to this erratic rotation with empty lines that are long and not laid at a constant grade. An ideal valve loca- tion is shown in Figure 4. If the final discharge point is more than about 2 feet above the valve and the system does not drain back into the dosing tank, check valves should be installed on the lines immediately following the valve and a pressure release hole or line should be installed just prior to the valve. This pressure release hole or line can go into a return line to the dosing tank or to a “minidrainfield” near the valve. In order for the valve to rotate reliably, no more than about 2 feet of head should remain against the valve to allow the rubber flap disk to return to its up position. In many cases, it may take from one minute to several minutes for the pressure in the valve to be lowered enough for proper rotation to occur. Special care should be taken when installing systems controlled by programmable timers to ensure cycling does not occur too rapidly. Figure 5 illustrates a valve assembly using check valves. Pumping downhill to the valve should be avoided unless the transport line is very short and the ele- vation between the discharge line out of the tank and the valve is less than about 2 feet. If the valve is located many feet below the dosing tank, random cycling may occur while the transport line drains through the valve at the end of the cycle. A pressure sustaining valve located just before the distrib- uting valve may overcome this problem in some instances. Dosing Tank Discharge Laterals Distributing Valve Assembly Transport Line Figure 4: Ideal valve location NTP-VA-1 Rev. 1.2, © 11/03 Orenco Systems®, Inc. Page 4 of 6 System Startup Refer to the Hydrotek Valve booklet that is provided with the distributing valve assembly for the sequencing of the valve outlets. The transport line should always be flushed with clean water before installing the valve. Any sand, gravel, or other foreign objects that may have been in the pipe during installation can easily become lodged in the distributing valve, causing malfunction. With the pump running, alternately close and open the ball valve on the distributing valve assembly to check proper rotation of the valve. (Note: If check valves are used on the lines after the distribut- ing valve, the pump may need to be turned on and off to allow the pressure to be released from the valve.) If visual operation of which zone is operating is not possible, watch the clear pipe on each line for indication of which zone is operating. Maintenance Annually check for proper operation by following procedures listed in the Hydrotek Valve booklet and system startup procedures listed above. Troubleshooting 1. PROBLEM: Valve does not change or cycle to next zone or outlet CAUSE: The stem and disk assembly is not rotating when water flow is turned off and then back on. SOLUTION 1: Ensure that there is no debris inside the cam. Clean and carefully reinstall the cam. SOLUTION 2: If fewer than the maximum number of outlets are being used, check the installation of the cam. Ensure that the stem and disk assembly is not being held down by an improperly installed cam. Refer to the cam replacement instructions. h Check Valves if h>2'-0" Distributing Valve Assembly Transport Line Dosing Tank Pressure Release Line if h>2'-0" Discharge Laterals Figure 5: Valve assembly below final discharge point NTP-VA-1 Rev. 1.2, © 11/03 Orenco Systems®, Inc. Page 5 of 6 SOLUTION 3: Remove the valve top and check for proper movement of stem and disk assembly. Check for and remove any debris or foreign objects that may jam or retard the movement of the disk. SOLUTION 4: Check for freedom of movement of stem and disk assembly up and down over the center pin in bottom of valve. Scale deposits may build up on the pin and hold stem and disk assembly down. Clean pin and again check for freedom of movement. SOLUTION 5: Be sure that all operating outlets are not capped and that the flow to operating zones is not restricted in any manner. This would cause pressure to build up in the valve and lock the stem and disk assembly in the down position. SOLUTION 6: The backflow of water from uphill lines may be preventing the valve from cycling properly. This can happen when the valve is placed too far below an elevated line. If the valve cannot be placed close to the high point of the system, a check valve should be installed near the valve in the outlet line that runs uphill from the valve and a drain line installed just prior to the valve to relieve the pressure. 2. PROBLEM: Water comes out of all the valve outlets CAUSE: Stem and disk assembly not seating properly on valve outlet. SOLUTION 1: Check for sufficient water flow. A minimum flow rate is required to properly seat the disk as shown in Table 1. SOLUTION 2: Remove the valve top and check the inside walls to ensure that nothing is interfering with the up and down movement of the stem and disk assembly inside the valve. SOLUTION 3: Make sure that the operating outlets are not capped and that the flow to the operat- ing zones are not restricted in any manner. 3. PROBLEM: Valve skips outlets or zones CAUSE: Pumping into an empty transport line — especially downhill — may cause the valve to skip outlets from pockets of air allowing the rubber flap disk to raise during a cycle. SOLUTION 1: Keep the transport line full. SOLUTION 2: If the line must remain empty between cycles, use a larger diameter transport line laid at a constant grade to prevent air pockets from forming. CAUSE: The stem and disk assembly is being advanced past the desired outlet. SOLUTION 1: Ensure that the correct cam for the desired number of zones is installed and that the outlet lines are installed to the correct outlet ports of the valve as indicated by the zone numbers on the top of the cam.

Page 6 of 6 Distributing Valves General Orenco’s Automatic Distributing Valve Assemblies are mechanically operated and sequentially redirect the pump’s flow to multiple zones or cells in a distribution field. Valve actuation is accomplished by a combination of pressure and flow. Automatic Distributing Valve Assemblies allow the use of smaller horsepower pumps on large sand filters and drainfields. For example, a large community drainfield requiring 300 gpm can use a six-line Valve Assembly to reduce the pump flow rate requirement to only 50 gpm. Orenco only warrants Automatic Distributing Valves when used in conjunction with High-Head Effluent Pumps with Biotube®Pump Vaults to provide pressure and flow requirements, and to prevent debris from fouling valve operation. An inlet ball valve and a section of clear pipe and union for each outlet are provided for a complete assembly that is easy to maintain and monitor. Ideal valve location is at the high point in the system. Refer to Automatic Distributing Valve Assemblies (NTP-VA-1) for more information.

The 4.57-acre property is located outside of Basalt, in an area where OWTSs and wells are necessary. Original design documents described the main house and ADU being served by separate OWTSs. Total bedroom count has changed and there is a desire to have both structures be served by the proposed OWTS. Design documents dated May 11, 2020 should be discarded. Legal Description: Lot 1, GABOSSI SUBDIVISION. Parcel ID: 2391-334-02-001 SITE CONDITIONS There is a main residence and accessory dwelling unit (ADU) on the property. The ADU will have 1- bedroom after the remodel and is currently served by an existing OWTS documented by Eagle County Individual Sewage Disposal System (ISDS) Permit 1705-97. This OWTS will be abandoned. The main house will have 4-bedrooms after the remodel. The proposed OWTS will serve both structures. A private well, located on the western side of the property, serves the residences. The well is located at least 50-feet from the proposed septic tank and at least 100-feet from the proposed soil treatment area (STA). The Roaring Fork River is located on the southern portion of the property. A ditch bisects the center of the property. While the sewer line will need to cross the ditch, all other components will be at least 50-feet from the ditch. Other easements are present on the property. Most notably, a 50-foot gas easement that crosses the northern portion of the property. This easement will need to be crossed with a sewer line, but no other OWTS component will be placed within the easement. The gas company must be notified prior to construction in the easement. The proposed STA will be located in the northern portion of the property, between the gas line easement and the electrical easement. It is relatively flat, sloping slightly (less than 5%) to the south. The area is currently utilized a yard. Page 2 There should be no traffic or staging of material over the future STA site to avoid compaction of soils prior to construction of the STA. Table 1 describes the minimum required setback of OWTS components to physical features on the property compared to approximate, proposed setback distances.

Visual and tactile soil analysis was completed by Carla Ostberg at the time of excavation.1 The materials encountered in the Test Pit #1 consisted of dark brown, moist, topsoil and rootzone to 6- inches, underlain by medium brown, moist, loamy sand with greater than 65% rock and cobbles to a maximum depth explored of 7.0-feet. No bedrock or groundwater was encountered. Excavation began on Test Pit #2 and we encountered an irrigation line. Not wanting to disturb more area in the proposed STA than necessary, we did not continue digging. A sample of the soils was taken from Test Pit #1 at 3-feet below grade. A sieved sample of the soil formed a ball, but no ribbon. Soil structure shape was single-grain and consistence was loose. Soil texture was gritty. Soils are classified as R-0 due to content of rock. The design will require an over-excavated, pressured dosed, unlined sand filter with a minimum of 3-feet of “Secondary Sand” filter material. A long term acceptance rate (LTAR) of 0.8 gallons per square foot, will be used to design the OWTS. 1 Carla Ostberg holds a Certificate of Attendance and Examination from the CPOW Visual and Tactile Evaluation of Soils Training.

An average daily wastewater flow of 675 GPD will be used. For the purposes of this OWTS design, Benchmark Elevation has been established as the existing sewer line elevation as it enters the existing septic tank (100’). CBO Inc. should be notified of any discrepancies or problems with grade elevations of proposed components during installation of the OWTS.

A double-sweep clean out should be added to each if one does not already exist. The system installation will include a new 1500-gallon, two-compartment concrete septic tank with an Orenco® Biotube Effluent Filter on the outlet tee. The sewer line exiting the septic tank must have a minimum 1% fall to the pump chamber. The sewer line will cross the top of the culvert. The sewer line should be encased at least 10-feet on each side of the ditch opening (see W4.0/1 Encasement Detail). This line should be insulated with blue board to protect from freezing. Any portion of the sewer line under the driveway or area subject to traffic must be minimum Schedule 40. A new 500-gallon, single-compartment concrete Valley Precast pump chamber with an Orenco® Biotube Pump Vault and an Orenco® PF3005 pump must be installed. The floats should be set to dose approximately 80 gallons each pump cycle, allowing approximately 13 gallons of drain back after each pump cycle. A pump curve is enclosed. The pump must be capable of a minimum design flow rate of 24.4 GPM and a minimum total dynamic head of 23.2 feet with 5 feet residual head at last orifice. The control panel for the pump must be located within line of sight of the septic tank. We recommend Valley Precast out of Buena Vista be contracted for start-up of the pumping system. Pump Table Dose Range Max = 182 gal. (675 GPD x 25% + 13 gal drain back) Min. 61 gal. (12 gal x 4) + 13 gal drain back Dose Setting 80 gallons/dose 13 gallons drain back (122 / 1.5” diameter pump line) Float Separation 500 gallon single-compartment Valley Precast concrete pump chamber 8” on/off float separation Pump Criteria 24.4 gallons per minute (GPM) 23.2 feet total dynamic head (TDH) Effluent will be pressure dosed through a 1.5-inch diameter pump line from the pump chamber to an Orenco® automatic distributing valve (ADV), model 6402. This pump line must have a minimum 1% grade for proper drain back into the tank after each pump cycle. The ADV must be placed a high point in the system and be placed in an insulated riser with access from grade. Screened rock must be placed below the ADV to support the ADV and to assure the clear pipes existing the ADV remain visible for future inspection and maintenance. Page 6 Effluent will be pressure dosed through 1.5-inch diameter distribution lines to an over-excavated, 12’ x 71’ unlined sand filter, split into two zones. A minimum of 3-feet of sand filter material will be installed in the over-excavated footprint. Sand filter material must be clean, coarse sand, all passing a screen having four meshes to the inch. The sand must have an effective size between 0.15 and 0.60 mm. The uniformity coefficient must be 7.0 or less. Material meeting ASTM 33, for concrete sand, with three percent or less fines passing 200 mesh sieve may be used. A gradation of the sand media must be provided. Laterals used to disperse the effluent must be surrounded by washed coarse screened gravel or crushed stone. All of the gravel or stone must pass a 2 ½-inch screen and must be retained on a ¾-inch screen. The manifold must be 1.5-inches in diameter. Laterals must be 1.5-inches in diameter with 5/32-inch diameter orifices facing down, spaced 3-feet on center (OC). We recommend Orenco® Orifice Shields be installed on the laterals at each orifice. Laterals will begin 2-feet from the edges of the filter, with 4-feet between each lateral. Each 1.5-inch diameter lateral must end in a sweeping ell facing up with a ball valve for flushing. A soil separation fabric should be placed over the gravel layer followed by approximately 1-foot of topsoil or other suitable soil able to support vegetative growth. COMPONENT SPECIFICATIONS The component manufacturers are typical of applications used by contractors and engineers in this area. CBO Inc. must approve alternative components prior to installation of the OWTS. Requests must be submitted, in writing, to our office for approval prior to installation. Component technical data sheets are available upon request. COMPONENT MANUFACTURER MODEL NO.

Alternatives may be considered or recommended by contacting our office. Construction must be according to Eagle County On-Site Wastewater Treatment System Regulations, the OWTS Permit provided by Eagle County Environmental Health Department, and this design. Page 7 INSTALLATION CONTRACTOR CBO Inc. expects that the installer be experienced and qualified to perform the scope of work outlined in this design. The installer must review this design thoroughly and coordinate with our office in advance of installation. Any additional conditions in this design or county permit must be completed and documented prior to final approval of the OWTS installation. Communication between the installer and this office is expected throughout the installation. INSTALLATION OBSERVATIONS CBO Inc. must view the OWTS during construction. The OWTS observation should be performed before backfill, after placement of OWTS components. Septic tanks, distribution devices, pumps, dosing siphons, and other plumbing, as applicable, must also be observed. CBO Inc. should be notified 48 hours in advance to observe the installation. In an effort to improve the accuracy of the record drawing, we request that the installer provide a sketch of the installation, including path of the sewer lines, water line installation (if applicable), septic tank location, STA location, and measurements from building corners or another fixed objects on the property. This sketch is most easily provided on Sheet W2.0 of the OWTS Design Packet. Photographs of the installation and final cover are also requested to supplement our installation documentation. REVEGETATION REQUIREMENTS An adequate layer of good quality topsoil capable of supporting revegetation shall be placed over the entire disturbed area of the OWTS installation. A mixture of native grass seed that has good soil stabilizing characteristics (but without taproots), provides a maximum transpiration rate, and competes well with successional species. No trees or shrubs, or any vegetation requiring regular irrigation shall be placed over the area. Until vegetation is reestablished, erosion and sediment control measures shall be implemented and maintained on site. The owner of the OWTS shall be responsible for maintaining proper vegetation cover. OPERATION INFORMATION AND MAINTENANCE The property owner shall be responsible for the operation and maintenance of each OWTS servicing the property. The property owner is responsible for maintaining service contracts for manufactured units, alternating STAs, and any other components needing maintenance. Geo-fabrics or plastics should not be used over the STA. No heavy equipment, machinery, or materials should be placed on the backfilled STA. Machines with tracks (not wheels) should be used during construction of the STA for better weight distribution. Livestock should not graze on the STA. Plumbing fixtures should be checked to ensure that no additional water is being discharged to OWTS. For example, a running toilet or leaky faucet can discharge hundreds of gallons of water a day and harm a STA. If an effluent filter or screen has been installed in the OWTS, we recommend this filter or screen be cleaned annually, or as needed. If the OWTS consists of a pressurized pump system, we recommend the laterals be flushed annually, or as needed. Page 8 11-24-2020 The homeowner should pump the septic tank every two years, or as needed gauged by measurement of solids in the tank. Garbage disposal use should be minimized, and non-biodegradable materials should not be placed into the OWTS. Grease should not be placed in household drains. Loading from a water softener should not be discharged into the OWTS. No hazardous wastes should be directed into the OWTS. Mechanical room drains should not discharge into the OWTS. The OWTS is engineered for domestic waste only. ADDITIONAL CONSTRUCTION NOTES If design includes a pump, weep holes must be installed to allow pump lines to drain to minimize risk of freezing. The pump shall have an audible and visual alarm notification in the event of excessively high water conditions and shall be connected to a control breaker separate from the high-water alarm breaker and from any other control system circuits. The pump system shall have a switch so the pump can be manually operated. Extensions should be placed on all septic tank components to allow access to them from existing grade. Backfill over the STA must be uniform and granular with no material greater than minus 3-inch. LIMITS: The design is based on information submitted. If soil conditions encountered are different from conditions described in report, CBO Inc. should be notified. All OWTS construction must be according to the county regulations. Requirements not specified in this report must follow applicable county regulations. The contractor should have documented and demonstrated knowledge of the requirements and regulations of the county in which they are working. Licensing of Systems Contractors may be required by county regulation. Please call with questions. Sincerely, CBO Inc. Reviewed By: Carla Ostberg, MPH, REHS Romeo A.

Originally we were going to use the existing system to serve the ADU, but plans changed and we decided to combine houses on one new system. The existing septic tank is approximately 3-feet from the new house foundation. This site has some challenges in that we have to maintain a high enough elevation of the septic tank to achieve fall for the sewer line to cross over the culvert that encases the ditch under the driveway. We also have to maintain 50-feet from the ditch to the septic tank, which pushes us pretty close to the house and there are several mature trees that we want to save, so we don't have many alternatives for a new area for the septic tank. The contractor is thinking the tank should stay in the same approximate location, which prompted the question of whether or not we could continue to use the existing septic tank. I did an inspection of the system several years ago. The tank appears to be in good shape and is 1500 gallons (same size as the proposed septic tank). Wondering if we can encroach slightly on the min. 5' separation between the new foundation and the septic tank. The foundation has already been poured, so we can show proper backfill between the foundation and existing tank if you wanted us to take some pictures. Let us know and feel free to call with additional questions. Thank you!

I think that is okay, especially since it is existing, and in good condition, the additional 2' would be a burden and have little to no benefit. We will get this in our queue for review. Thanks!

Also, please secure permission to cross the utility easement belonging to the gas company and provide us with that letter, needed prior to us issuing the permit.

Permit# OWTS-020231-2020 was issued on 12/9/2020. I show that Stangl & Son Builders issued check# 4524 on 11/30/2020 for the review and permit fee of $800. We have one minor change, keeping the exisng sepc tank in line with the new system, as opposed to digging it up and swapping it out with a new one. Carla outlines that below. You and I discussed this back on March 25th on the phone. I have forwarded this email to Roy Watkins with Black Hills Energy High Pressure Div. He has been onsite for preconstrucon locates and consultaon. He will be onsite at the me we dig and cross over the gas easement. Roy will send your request for a leer of sign off to his manager. Hope to have that for you early next week.

I thought the change was relative to the new design and not the previous, but now I see that is the only change here. I will not need a new application nor fee. I will look for the easement crossing approval next week. Thank you! [Quoted text hidden]
