Finishing Touch Dirtworx installed the system. The existing septic tank and existing soil treatment area (STA) were abandoned in place. The septic tank was pumped, collapsed, and remaining void filled with gravel, sand, or compacted soil. The new OWTS design is based on 3-bedrooms. An average daily wastewater flow of 450 GPD will be used. A new double-sweep clean out was installed near the residence. A new, minimum 4-inch diameter Schedule 40 sewer line with a minimum 2% fall from the residence to the septic tank was also installed. The trench was bedded with screened rock or road base and covered with Blue Board insulation for protection against freezing and settling. The OWTS installation included a new 1500-gallon, two-compartment septic tank with an Orenco® ProPak pumping system and PF3005 pump in the second compartment of the septic tank. The floats were set to dose approximately 80 gallons each pump cycle. The control panel for the pump is located within line of sight of the septic tank (mounted on the wall near the garage). Valley Precast out of Buena Vista was contracted to perform start-up on the pumping system. Effluent is pressure dosed through a 1.5-inch diameter pump line to a Model 6403A Automatic Distributing Valve (ADV) which was located at the high point and accessible from grade in an insulated riser. The 1.5-inch diameter pump line has a minimum 1% grade for proper drain back into the septic tank after each pump cycle. The ADV has three 1.5-inch diameter outlets for each transport pipe leading to three separate over-excavated unlined sand filter beds. Each bed, measuring 6’ x 25’, was over-excavated approximately 3-feet below native grade to the rock layer. There was at least 6-feet of separation (undisturbed soil) between the beds. A minimum of 3-feet of sand filter material was installed in each over-excavation. Laterals were 1.5-inches in diameter with 3/16-inch diameter orifices facing down, spaced 2-feet on center, installed on the GeoMat™ with the filter fabric over the laterals. Laterals were be placed 2-feet from the edges of the bed. Each 1.5-inch diameter lateral ends in a sweeping ell facing up with a ball valve for flushing. Laterals were covered by a soil separation fabric and at least 1-foot of topsoil or other suitable soil able to support vegetative growth. The OWTS was generally installed according to specifications. This observation is not a guarantee of workmanship and/or parts and materials. ALL SERVICE septic, LLC 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 of the expertise of the installer, soil type, and weather conditions. Please call with questions.

The 2.3-acre property is located outside of Basalt, in an area where OWTSs are necessary. Original design documents dated February 16, 2017 and May 31, 2019 should be discarded and replaced with these dated March 23, 2020. Regulations changed since the original design document and this design reflects updated consistent with current regulation. Additionally, the size of the septic tank was changed to better meet required retention times. Parcel ID: 2391-224-01-005 Legal Description: OAK RIDGE I Lot: 6 BK-0321 PG-0624 BK-0475 PG-0369 WD 12-04-87 BK-0498 PG-0548 QCD 01-04-89 BK-0747 PG-0270 SWD 12-18-97 SITE CONDITIONS A 2-bedroom, single-family residence presently exists and is utilizing an existing OWTS. The existing 1000-gallon concrete septic tank is located under the driveway, as is a portion of the existing 12’ x 40’ gravelless chamber bed soil treatment area (STA). There is a desire to upgrade the existing system in the scope of the remodel, which will result in a total of 3-bedrooms. The property slopes to the south at approximately 15% with some areas flattening out to allow for a narrow bed configuration of the STA. The area of the proposed STA, located on the east side of the existing driveway, is vegetated with sage and native grasses. Efforts will be made to avoid disturbing clusters of scrub oak north of the proposed STA. The existing water line runs on the west portion of the property and will be located at least 25-feet from any OWTS component. An electrical line and other utilities run in a trench just east of the proposed STA. This trench has been located and will be well marked during excavation of the STA. Page 2 SUBSURFACE The subsurface was investigated on January 30, 2017 by digging four soil profile test pit excavations (Test Pits). A visual and tactile soil analysis was completed by Carla Ostberg at the time of excavation.1 The materials encountered in all four Test Pits consisted of approximately 3-feet of dark brown, clayey topsoil. At 3-feet, we encountered backhoe refusal in all of the Test Pits. Extremely large basalt boulders or possibly a shelf rock limited our ability to explore below 3-feet. No groundwater was encountered. STA sizing is based on an unlined sand filter with 3-feet of sand filter material (Secondary Sand). A long term acceptance rate (LTAR) of 0.8 gallons per square foot will be used to design the OWTS in accordance with Table 10-1 presented in the Eagle County On-Site Wastewater Treatment System Regulations. Maximum depth excavated in all Test Pits approximately 3-feet. 1 Carla Ostberg holds a Certificate of Attendance and Examination from the CPOW Visual and Tactile Evaluation of Soils Training. Page 3 Sieved sample of clayey topsoil (to be over-excavated) DESIGN SPECIFICATIONS We have chosen unlined sand filters for this design due to a limiting layer discovered at 3-feet below grade and the restriction in area based on the electrical line running through the eastern portion of the property and water line on the western portion of the property. Beds will be positioned in level areas of the property and step down the hillside toward Mountain View Road. The existing septic tank and existing STA will be abandoned in place. The septic tank must be pumped, collapsed, and remaining void filled with gravel, sand, or compacted soil. The new OWTS design is based on 3-bedrooms. An average daily wastewater flow of 450 GPD will be used. Design Calculations: Average Design Flow = 75 x 2 x 3 Bedrooms = 450 GPD LTAR = 0.8 GPD/SF (unlined sand filter, Secondary Sand) 450 GPD / 0.8 GPD/SF = 562.5 SF (3) pressure dosed unlined sand filter beds (6’ x 31.5’) A new double-sweep clean out must be installed near the residence. A new, minimum 4-inch diameter Schedule 40 sewer line with a minimum 2% fall from the residence to the septic tank must also be installed. The trench must be bedded with screened rock or road base and covered with Blue Board insulation for protection against freezing and settling. The OWTS installation must include a new 1500-gallon, two-compartment septic tank with an Orenco® ProPak pumping system and PF3005 pump in the second compartment of the septic tank. The floats should be set to dose approximately 60 gallons each pump cycle. 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 to perform start-up on the pumping system. Effluent will be pressure dosed through a 1.5-inch diameter pump line to a Model 6403A Automatic Distributing Valve (ADV) which must be located at the high point and accessible from grade in an insulated riser. The 1.5-inch diameter pump line must have a minimum 1% grade for proper drain back into the septic tank after each pump cycle. The ADV will have three 1.5-inch diameter outlets for each transport pipe leading to three separate over-excavated unlined sand filter beds. Laterals will be connected with 1.5-inch diameter manifolds. Page 4 Effluent will be pressure dosed through a 1.5-inch diameter pump lines to two beds, each 6’ x 31.5’. 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 submitted to this office prior to obtaining the sand. Laterals must be 1.5-inches in diameter with 3/16-inch diameter orifices facing down, spaced 2-feet on center, installed on the GeoMat™ with the filter fabric over the laterals. Laterals should be placed 2-feet from the edges of the bed. Note that the GeoMat™ is 39-inches wide, so two GeoMats™ placed on the 6- foot wide bed will overlap slightly. All material associated with the GeoMat™ installation must be proprietary products associated with the GeoMat™, including orifice shields and geotextile fabric. Manufacturer instructions must be followed regarding installation of the GeoMat™. Each 1.5-inch diameter lateral must end in a sweeping ell facing up with a ball valve for flushing. Laterals must be covered by a soil separation fabric and at least 1-foot of topsoil or other suitable soil able to support vegetative growth. There shall be no cobble-sized (<2.5”) or greater rock in final cover over the GeoMat™. Portions of the unlined sand filters extending above native grade must have a minimum 3:1 (horizontal:vertical) slope and must either be graded or crowned for proper drainage. The component manufacturers are typical of applications used by contractors and engineers in this area. 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. 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 irritation 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. 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. 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 Page 5 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. Excavation equipment must not drive in excavation of the STA due to the potential to compact soil. 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. INSTALLATION OBSERVATIONS ALL SERVICE septic, LLC 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. ALL SERVICE septic, LLC should be notified 48 hours in advance to observe the installation. LIMITS: The design is based on information submitted. If soil conditions encountered are different from conditions described in report, ALL SERVICE septic, LLC 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.

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.

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 shield should be rotated such that the flat surface and the top orientation mark are both in the 12 O’clock position. This should result in the shield positioned directly over the orifice. Generously apply Premier brand One-Step Pipe Cement Multi-Purpose Clear, or equal, to the surfaces where the shield and pipe meet. The use of a foam brush will help with this; the round applicator is not effective. Let glue sufficiently dry before rough handling and/or sliding into GeoMat. Note the above steps are intended to prevent shields from moving around during insertion into GeoMat; not for rough handling. When better adhesion is necessary, for transportation, etc. use PVC primer and solvent cement on all surfaces where the pipe and shield touch and then snap on shield in correct location.

Design Criteria for Geomatrix Systems, GeoMatTM as a Distribution Product Design Criteria 1.A septic tank consistent with section 43.9(A)and 43.9(B)must precede the distribution media. An effluent screen consistent with section 43.3(50) and 43.9(J) installed prior to the distribution media is recommended, but not required unless a local requirement. Pretreatment for non-residential kitchens must include adequate separate grease separator tank(s) prior to the primary septic tank(s) as required in section 43.9(J) of Regulation 43. Dave Potts, Geomatrix Systems, LLC July 17, 2017 On-site Wastewater Treatment System Distribution Product Acceptance Page 2 of 3 2. The design of an OWTS utilizing the GeoMat TM for distribution shall adhere to the following criteria: a. The required design flow shall be determined based on daily flow requirements defined in local OWTS regulations consistent with section 43.6(A) of Regulation 43. b. The total soil treatment area square footage required shall be determined consistent with the requirements of section 43.10(C) of Regulation 43. This requirement is applicable to both trench and bed configurations. 1) Where the GeoMat TM is placed directly on the in-situ soil, the multiplier noted in Table 10-3 (Category 2) of Regulation 43 for “other manufactured media” (0.9) may be applied for calculating the minimum soil treatment area. 2) Where the GeoMat TM is placed on 6” of ASTM C33 sand, the multiplier noted in Table 10-3 of Regulation 43 (Category 3) for “enhanced manufactured media” (0.7) may be applied for calculating the minimum soil treatment area. c. Effluent must be applied to the GeoMat TM through the use of pressure distribution as defined in section 43.10.E.3 of Regulation 43. Therefore, all systems utilizing the GeoMatTM must be designed by a professional engineer. d. End-sweeps/cleanouts shall be provided on the terminal end of each lateral line. These can be used for annual cleaning or flushing the laterals and for distal head pressure measurements. e. In a bed installation, the GeoMat TM may be installed with spacing between the edges of adjacent GeoMatTM panels or may be butted edge to edge. However, in either case, the total square footage of GeoMatTM shall comply with item “b” above. f. The maximum width of a bed installation for a GeoMat TM accepting TL1 effluent shall be 12 feet to comply with Section 43.10(F)(2) of Regulation 43. g. In a trench installation, the width of the GeoMat TM must cover at least 90% of the trench bottom in order to receive credit for the entire width of the trench. In certain instances where the 39” GeoMatTM is installed in a 36” trench, the GeoMat TM may travel up the sidewall of the trench not more than 2”. The total square footage of GeoMatTM shall comply with item “b” above. h. Trench designs shall provide for the required 4 feet of undisturbed soil between adjacent trenches, sidewall to sidewall, as defined in Section 43.10(F)(1)(b) of Regulation 43. i. Bed designs shall provide for the required 6 feet of undisturbed soil between adjacent excavations, sidewall to sidewall, as defined in Section 43.10(F)(2)(b) of Regulation 43. j. While preparing the base for the GeoMat TM installation, the bottom of the excavation shall be raked and all cobble-sized (>2.5”) rocks should be removed. Cobble-sized or greater rocks shall also be removed from the material used for the final cover over the top of the GeoMatTM. k. Geotextile fabric provided by Geomatrix shall be placed around the entire perimeter of the GeoMatTM in accordance with manufacturer requirements. This fabric is specific to this product. Only the fabric provided by Geomatrix may be used. l. A final soil cover over the GeoMat TM of 10” – 18” of a Soil Type 1 or Soil Type 2 material is recommended, crowned to promote surface runoff. m. Vertical separation distances to a limiting layer for the soil treatment area as defined in Table 7-2 of Regulation 43 shall be measured from the bottom of GeoMatTM when placed directly on in-situ soil. Where GeoMatTM is placed on 6 inches of ASTM C33 sand, vertical separation distances to a limiting layer for the soil treatment area as Dave Potts, Geomatrix Systems, LLC July 17, 2017 On-site Wastewater Treatment System Distribution Product Acceptance Page 3 of 3 defined in Table 7-2 of Regulation 43 shall be measured from the bottom of the 6- inch sand layer underlying the GeoMatTM. Horizontal separation distances for the soil treatment area as defined in section 43.7 of Regulation 43 shall be measured from the nearest sidewall of the bed or trench excavation. 3. In addition to these design criteria, other provisions of Regulation 43 and local regulations also apply to a specific design as well as good OWTS design practice. The Division does not approve manufacturer design manuals. Manufacturer provisions shall not be applicable if those provisions are not consistent with Regulation 43, these design criteria, and the regulations adopted by the local board of health for the design location. Local public health agencies will review proposed designs to confirm consistency with Regulation 43, these design criteria, the local board of health regulations adopted pursuant to Regulation 43, and good OWTS design practice. 4. Reductions in soil treatment area size shall be as described in section 43.10(C)(4) of Regulation 43. Use of the distribution product in a design claiming a higher level treatment designation is dependent on a separate treatment product prior to the distribution product, or a separate higher level treatment acceptance by the Division for this product, and the rating identified in the acceptance for the treatment product. Reductions in soil treatment area size or separation distances based on higher level treatment may not be applied unless the local public health agency has a maintenance oversight program in place as described in section 43.14.D of Regulation 43. In locations where the local public health agency has not adopted a maintenance oversight program, the distribution system may be used but only with soil treatment area size and separation distances consistent with treatment level TL1 requirements. 5. Design flow for single-family residential designs may vary based on the regulations adopted by the local board of health for the design location. Design flow values and strengths for multi-family and commercial systems shall be consistent with section 43.6(A)(4). Therefore, all design criteria in this acceptance are based on total gallons per day and the assumption of residential strength wastewater. 6. Design shall provide access at grade to any components as described in section 43.9(F) and (G) in additional to any additional access ports as provided for in the engineered drawings. The owner of the OWTS is responsible for arranging proper design, operation, and maintenance of the OWTS facility.

GeoMat is nominally 1” thick and available in widths of 6, 12, and 39 inches. It is comprised of an entangled filament core covered by a hydroscopic membrane with an incorporated low-pressure distribution pipe. Due to the shallow burial depth and the high surface area to void space ratio in the GeoMat, gas exchange has been shown to be significantly greater in GeoMat than in other leach field technologies. This increased oxygen transfer rate results in increased removal of pathogens, B.O.D., T.S.S., and nutrients such as nitrogen and phosphorus in a shallower soil profile. The combination of the highly transmissive core and hygroscopic membrane draw the water between the application points and uniformly apply the water to the surrounding soil. The soil then draws the water away from the surrounding membrane through capillary action. This results in a much more uniform application of water to the soil and minimizes the point loading associated with other low profile systems. In general, GeoMat can be utilized in many different configurations; please check with your regulatory agency or contact Geomatrix for the configurations that may be available in your area. GeoMat can be installed in trench and bed layouts and function with gravity, pump to gravity, and pressure distribution (PD) system configurations. GeoMat with 6 inches of ASTM C -33 sand beneath it can be configured to meet NSF Standard 40. GeoMat can also be used for subsurface irrigation and nutrient reuse. Geomatrix products are the result of intensive research and development, including in house and third-party testing. Test reports are availab le by contacting Geomatrix. Geomatrix products are manufactured under one or mo re of the following U.S. patents; 6,485,647, 6,726,401, 6,814,866, 6,887,383, 6,923,905, 6,959,882, 6,969,464, 7,157,011, 7,309,434, 7,351,005, 7,374,670, 7,465,390; Also see patents at www.geomatrix systems.com. Warning: Only Authorized service providers should install, inspect, maintain, or troubleshoot the GeoMat Wastewater Treatment System. 5 2.0 GEOMAT TREATMENT CAPABILITIES When the wastewater is nonresidential in strength, the BOD and TSS should be reduced utilizing pretreatment or a SoilAir system to ensure that there is sufficient oxygen to reduce BOD; alternatively the size of the GeoMat system should be increased proportionately to account for the higher BOD. Contact Geomatrix for assistance on projects other than single family homes. 3.0 COMPONENT HANDLING AND INSPECTION Upon delivery inspect to ensure no damage has occurred to the components. Keep the GeoMat and distribution piping clean and free of soil, dirt, oil, grease , PVC saw dust and associated debris, and any other substance that m ay impede performance. Although GeoMat is rugged, it should be handled with care. If components are not used immediately after delivery or purchase, they should be stored away from sunlight and in a fashion that will not damage their shape over time. Rolls can be stacked up to 3 high, circle side down. 6 4.0 SYSTEM COMPONENTS GeoMat System Components Component Function 1 Source Generates wastewater 2 Septic Tank or Pretreatment Unit Pre-treats wastewater 3 Effluent Filter Strains wastewater 4 Optional Pump Chamber Accumulates water for lifting and pressure distribution to GeoMat 5 Distribution Piping Delivers wastewater to GeoMat 6 GeoMat Treats and disperses wastewater 7 Optional Cleanout/ Distal Head Port Provides access for servicing distribution piping and measurement of distal head 1 2 3 4 5 6 7 7 5.0 FLOW PATH IN A PROPERLY CONSTRUCTED GEOMAT SYSTEM IS: 5.1.

In pressure applications, the minimum pipe diameter is 1 inch. 8.0 SITE LAYOUT GeoMat must be installed according to applicable state and/or local regulations. If unsure of the installation requirements for a particular site, contact Geomatrix, your designer, engineer, and/or regulatory agent. 8.1 System Sizing See Geomatrix Vermont GeoMat Design Manual for specific guidance in designing GeoMat Systems. 8.2 Excavation considerations: GeoMat in a Sand Bed A minimum of 6 inches of approved sand must be utilized beneath the GeoMat and 2 inches of sand should be placed over the GeoMat fabric membrane. GeoMat Flat should be installed utilizing the following parameters:  GeoMat laterals can be butted together, sidewall to sidewall, when laid flat and in a bed configuration; however, it is best to pull them apart by a minimum of 4 inches edge of core to edge of core.  A minimum of 12 inches of sand should surround the perimeter of the GeoMat in a bed configuration. GeoMat Edge should be installed with a minimum spacing of 6 inches center to center. GeoMat in Native Soil GeoMat can be installed directly in native soils. GeoMat Flat when installed in native soils should be installed utilizing the following parameters:  GeoMat shall be separated, sidewall to sidewall, from adjacent rows of GeoMat by the 2 times the width of the GeoMat utilized. o GeoMat 600 = 12 inches o GeoMat 1200 = 24 inches o GeoMat 3900 = 78 inches  When specifically configured for gravity flow, and generally, on all configurations, the use of SoilAir should be considered. If SoilAir is not going to be installed, it is advisable to install a conduit from the outlet baffle of the septic tank to the future SoilAir enclosure location. The SoilAir enclosure should be located where a power 10 supply can be readily configured. It is also recommended, that an airline be run from the SoilAir enclosure location and connected to the wastewater supply pipe serving the GeoMat. This air line should be a minimum of 2 inch ID SCH40 PVC for a 5 bedroom or smaller single family home. Please contact Geomatrix for airline sizing on other projects. The air line should be pitched downwardly from the SoilAir enclosure location to the wastewater supply pipe and capped. These components are inexpensive and will facilitate simple remediation of the system, if necessary in the future.  Contact Geomatrix for SoilAir™ information and design assistance with SoilAir Systems. When installed in other than Class I native soils a minimum of 2 inches of approved sand is required beneath, to the sides, and above the GeoMat. 8.3 Maximum Lengths In gravity applications, GeoMat piping runs should not exceed 50 feet without a wastewater feed point. With pressure distribution, there is no maximum length for GeoMat piping runs; however, designs should result in a less than 10% flow differential between the first and last orifice. 11 9.0 SITE PREPARATION The area directly above and adjacent to any septic system should be protected from heavy vehicle traffic and excess weight loads before, during and post construction. Prior to construction, it is recommended that the proposed septic system location be staked and flagged/fenced to prevent encroachment during home construction. If vehicle encroachment is expected to be a problem, after construction, barriers such as garden timbers, railroad ties, fences, walls, etc. should be used to protect the septic system area. Do not install the system in wet conditions or in overly moist soil; this can cause smearing and compaction of the native soil horizons. The soil between the dispersal trenches shall remain undisturbed when practical and not in a bed configuration. If the presence of boulders and/or other obstacles makes trench construction impractical, the entire leach field area may be excavated as necessary and backfilled with a minimum 6 inch layer of approved sand to the design elevation. 9.1. Use the design plan and an engineer scale to measure the location of the system components on the plan from an existing physical or natural feature. Use a tape measure and swing ties from the same existing physical or natural features on the plan for location in the field and transfer the bench mark elevations if too far to work with. If unsure how to locate these on the plan, please contact Geomatrix, your designer, engineer and/or regulatory agent. Set stakes for location and elevation reference points. Ensure trees and shrubs are removed within 10 feet of the GeoMat to prevent root intrusion. No Weeping Willow or Black Locust trees shall be within 30 feet of the GeoMat. These separation distances can be minimized through the use of root barriers. Please contact Geomatrix for assistance. 9.2. Excavate system area to design elevation. Ex cavation depth should allow for approved sand below the GeoMat if required. 9.3. The bottom of excavation must be level. Excavation should be sufficiently large enough to accommodate GeoMat system design width and length. Rake the bottom and sides of the excavation to provide proper scarification and remove stones larger than 1 ½ inches and any other debris. In fine textured soils prone to compaction, minimize walking in the excavation to prevent compaction and loss of soil structure. 12 Heavy equipment should be kept off the sand base. If unavoidable, a tracked machine with a ground pressure not exceeding 2.5 psi may be utilized, with the use of ¾ inch plywood over the sand as support, to cross the sand base. You must avoid multiple trips over the same area, abrupt starting and stopping and excessive time spent working in one location on the sand base. All turns should be made beyond the sand footprint and only track in a straight line across the sand bed. Operating a machine on the bed should only be done if absolutely necessary. In summary, uniform sand density is critical to system performance and can be negativel y impacted by machinery and other static and dynamic loads on the sand base. 10.0 GEOMAT INSTALLATION 10.1. GeoMat Flat (Horizontal) Installation 10.1.1. Roll out GeoMat. Cut the GeoMat to desired length plus 4 inches. 10.1.2. Separate the core from the fabric. Cut out 2 inches of core from GeoMat ends, leaving the fabric intact to facilitate future stapling of the ends once the piping is installed. Piping should be free of saw dust and associated debris before joining. It is best to use a ratcheting PVC pipe cutter. PVC saw dust and associated debris can clog orifices in the laterals, keep pipe ends temporarily sealed to avoid soil or other materials from entering the pipe during installation. 10.1.3. Install laterals into the GeoMat by feeding it in from one end. Ensure that the orifices or perforations are aligned and oriented as desired. Glue distribution pipe together using two-part solvent weld glue, and SDR 35 or SCH40 PVC fittings according to manufacturer’s specifications. Piping entering the GeoMat should pitch to the GeoMat or back to the septic or pump tank in a free-draining manner to prevent freezing. 10.1.4. When pressure distribution is utilized, install a distal head port/cleanout at the 13 terminal end of each lateral. Extend this to a convenient location a minimum of 6 inches from the end of the GeoMat. A length of non -perforated pipe of the same size and construction as the distribution pipe in the GeoMat and coupler may be required. Connect a sweep 90⁰ elbow or two 45⁰ elbows to this extension pipe. The sweep elbow can be terminated with a ball valve, expandable gripper plug or threaded end cap. Glue piping components together as described above. The distribution piping should not have any holes / orifices outside of the GeoMa t. This distribution line extension pipe and associated fittings should pitch back to the GeoMat to prevent freezing. 10.1.5. Make certain that distribution pipe is centered in the GeoMat on top of core. Make certain that the perforation / orifices are equidistant from the ends of the GeoMat. Using an Arrow P22 stapler (or equivalent), seal ends by stapling the top fabric to the bottom fabric, being careful to seal the fabric tightly around where the pipe enters and exits the GeoMat. Use sufficient staples to ensure that sand cannot enter the core. Carefully move mat along ground, if it is not already in desired location and keep inside of pipe clean. 10.1.6. Again, ensure that the orifices or perforations are located, aligned, and oriented as desired. Connect the GeoMat distribution pipe to the septic tank or pretreatment unit, pressure manifold, distribution box, pump chamber, etc., per system design. 10.1.7. Before backfilling, ensure that distribution lines are centered on the GeoMat core. Confirm that all piping and the GeoMat are secure, properly glued and in the correct position and elevation. Take pictures, record all measurements and notify the applicable regulatory agency for inspection if necessary. 10.2. GeoMat Edge (Vertical) Installation 10.2.1. Roll out GeoMat. Cut the GeoMat to desired length plus 4 inches. 10.2.2. Separate the core from the fabric and cut out 2 inches of core from each end of the GeoMat. Leave the fabric intact to facilitate stapling and sealing after installing the piping. The interior and exterior of the p iping should be free of saw dust and associated debris before joining. Best results are achieved by utilizing a PVC pipe shear. PVC saw dust and associated debris can clog orifices in the laterals. Keep pipe ends temporarily sealed to 14 avoid soil or other materials from entering the pipe during installation 10.2.3. Install laterals into the GeoMat by feeding it in from one end. Ensure that the flat section of the orifice shield is aiming down and contacting the core. Glue distribution pipe together using two-part solvent weld glue and Sch. 40 PVC fittings, according to manufacturer’s specifications. Piping on the proximal or distal ends of the GeoMat should pitch to the GeoMat or back to the septic or pump tank to facilitate draining and prevent freezing. 10.2.4. Install a distal head port/cleanout at the distal end of each lateral. Extend the interior distribution pipe a minimum of 6 inches past the end of the GeoMat. A length of non-perforated pipe, the same size and specification as the interior distribution pipe and coupler, may be required. Connect a sweep 90⁰ elbow or two 45⁰ elbows to this distal end. The sweep elbow(s) can be terminated with a ball valve, expandable gripper plug or threaded end cap. Glue piping components together as described above. The distribution piping should not have any holes / orif ices beyond the GeoMat core. This distribution pipe, with or without the extension pipe, should pitch back to the GeoMat to prevent freezing. 10.2.5. Fasten pipe into place inside the GeoMat with Geomatrix stake clips on approximately 24 inch centers. 10.2.6. When sealing the ends of the GeoMat, be careful to seal/staple the surrounding fabric membrane tightly around the pipe entering and exiting the GeoMat 15 10.2.7.A GeoMat Edge in a Sand Bed Layout area where GeoMat will be located. Place the GeoMat with the interior piping and stake clips (previously installed), into the rough location where it will be backfilled. Turn the GeoMat assembly on edge, pipe and clip on top, and slide the GeoMat spacing templates over the GeoMat assemblies to maintain the required 6 inch spacing between GeoMat. Move the GeoMat, installed in the spacing templates, into the desired position. Using leveling equipment, push stakes into the sand base until GeoMat is set at desired elevation. Connect Interior GeoMat piping to the supply manifold. 10.2.7.B GeoMat Edge in Native Soils Measure out where the GeoMat and associated piping will be located. Utilizing mason’s line, paint, laser level, etc. mark out the location where the GeoMat laterals and associated piping will be located. Excavate to the desired elevation with excavating or trenching equipment. Place sand fill in trench bottom if required. Place GeoMat and previously installed interior distribution piping and stake clips into trenches. Push stakes into trench bottom to desired elevation, as determined by leveling equipment. Connect interior GeoMat piping to the supply manifold. 10.2.8. Confirm that the orifices and shields are aligned and oriented with the flat side facing the GeoMat core Complete piping the system per design. 10.2.9. Before backfilling, ensure that all piping and the GeoMat are secure, properly glued and in the correct position and elevation. Take pictures, record all measurements and notify the applicable regulatory agency for inspection if necessary. 11.0 OPTIONAL AIR SUPPLY LINE 11.1 It is recommended that a n air supply line and a float switch conduit be installed in case system remediation is necessary, at some point in time, due to time, hydraulic or organic overloading. For typical installations on a 5 bedroom or smaller single family home with runs of 50 feet or less, the air supply line should be a minimum of 2 inch SCH40 PVC. Runs from 50 - 200 feet should be a minimum of 3 inch SCH40 PVC. Contact Geomatrix for runs longer than 200 feet. The air supply line should pitch towards the GeoMat and is installed by teeing into the distribution piping anywhere downstream of the septic tank or pump tank at an elevation equal to or higher than the bottom elevation of the GeoMat. The air supply line is then 16 extended with appropriate fittings to a location that would be convenient for future connection to a SoilAir Blower. Glue piping components together as described above. It is also advisable to install a conduit f rom the outlet baffle of the septic tank or from the pump chamber to the future SoilAir enclosure location. This conduit will be potentially utilized for a float connection to control the SoilAir blower at some time in the future.. 12.0 BACKFILLING 12.1. Carefully place approved sand or suitable soil on the GeoMat to hold it in place for backfilling. Gently cover the GeoMat with a layer of approved sand or suitable fill to the top of the distribution pipe, being careful not to drop backfill material from an elevation higher than 18 inches. Install valve boxes over the distal ports if present. Final cover material for placement over the sand should be clean and free of stones larger than 1½ inches and debris. This cover material should be suitable for growing grass. Acceptable cover depth over the GeoMat distribution laterals should be from 6 – 24 inches; 12 inches is typical. Whatever depth is selected, it is recommended that the depth of cover should ideally not vary by more than 15% across the entire system and should extend a minimum of 18 inches beyond the sand bed footprint, if present. Final backfill should be such that surface water drains away from the GeoMat system and associated tanks. Heavy equipment should be kept off the system. If unavoidable, a tracked machine with a ground pressure not exceeding 2.5 psi may be utilized, with the use of ¾ inch plywood over the system as support to cross the system if a minimum of 12 inches of specified material is over the internal GeoMat distribution piping. You must avoid multiple trips over the same area, abrupt starting and stopping , and excessive time spent working in one location. All turns should be made beyond the sand footprint and only track/run in a straight line across the system. Operating a machine on the bed should only be done as absolutely necessary. In summary, material densities are critical to system performance and can be negatively impacted by machinery and other static and dynamic loads on and around the system. 17 Uniform cover depth, material consistency, permeability, and compaction across the entire GeoMat system results in consistent oxygen transfer to the entire system; this results in uniform performance. 12.2. Cover material should be graded to direct storm and surface water away from the system. Seed and mulch disturbed area immediately after installation to stabilize soil. 13.0 For repair or replacement of damaged system components please contact Geomatrix Systems, LLC at info@geomatrixsystems.com or 860-510-0730; or your authorized dealer. 18 STANDARD LIMITED WARRANTY (a) This warranty applies on to the original purchaser (“Purchaser”) and is non-transferrable.
