Hall, PE Date: May 22, 2024 Re: OUT OF BOUNDS RANCH – ONSITE WASTEWATER SYSTEM INTRODUCTION Moab Geotechnical Group (MGG) has prepared this Technical Memorandum (TM) to provide a new wastewater treatment system for the proposed Toy Barn structure at Out of Bounds Ranch in Carbondale, Colorado. It is understood that the structure will be approximately 14,000 square-feet and be supported by a single restroom. This submittal has been revised from the original, dated April 23, 2024, to include a lavatory, dishwasher, and a kitchen sink with garbage grinder in addition to the water closet and laundry washer. The plans have been updated with additional treatment area as required, and revised to clarify that the chamber end caps are not counted in the treatment area. SITE INVESTIGATION Taylor Hall performed soil analyses on two test pits to determine the feasibility of an onsite wastewater system in the proposed wastewater disposal area. Soil strata was similar between both test pits, with the dominant unit used for the design classifying as sandy clay loam with a blocky structure, Soil Type 3 per Table 10-1 of Reg. 43. Groundwater or indications of groundwater were not identified in the field investigation. Bedrock or limiting layers were not identified in either test pit. The soil evaluations forms are provided included in Appendix B. Sheet 2, attached, illustrates the approximate location of the test pits. ONSITE WASTEWATER SYSTEM FEASIBILITY The feasibility for the new onsite wastewater absorption system to service the proposed development was performed in accordance with Garfield County Amended Colorado Department of Health and Environment (CDPHE) Regulation 43. The proposed structure will be supported by a well that is more than 100 feet offset from the onsite wastewater treatment area. Both this well and the well on the adjacent parcel are illustrated on Plan Sheet 2. The well locations are based on information from the Colorado Department of Water Resources. Appropriate offsets from features set forth in Table 7.1 of Reg.43 have been incorporated into the design. The following exhibit summarizes relevant information to the feasibility assessment.

The planned structure will have one water closet (toilet) including a lavatory (sink), a laundry washer, a dishwasher, and a kitchen sink with garbage grinder serving an estimated five people. In accordance with Table 6.2 of Reg 43 a daily wastewater flow of 302 gpd was used for the design. Proposed Onsite Wastewater Absorption System A total of 1,500 gallons of septic volume will be provided via a Roth HDPE septic tank. The septic tank will be buried about two feet below existing site grade. Risers will be taken to the surface to allow for tank access. The absorption system will consist of two 104-foot-long type A chambered trenches, providing 624 ft2 of treatment area, laid out as illustrated in Sheet 2. Plans and details for the construction, installation, and maintenance of the system are provided in the accompanying sheets. CLOSING This Feasibility TM has been prepared to summarize the information required by Garfield County Amended Colorado Department of Health and Environment (CDPHE) Regulation 43 for the proposed new onsite wastewater treatment system for the future structures to be located at Out of Bounds Ranch in Carbondale, Colorado. The attached sheets provide a summary of the information needed to construct the new system. Prior to backfilling the absorption area, you should contact Garfield County and Moab Geotechnical Group for inspection.

The top of the baffles or sanitary tees shall extend at least 6 inches above the liquid level in order to provide scum storage, but no closer than 1 inch to the inside top of the tank. 28.Liquid depth of tanks shall be at least 30 inches. GENERAL NOTES FINAL INSPECTION The regulatory authority shall inspect the entire installation before backfilling to determine compliance with this rule. Some components or system types require additional testing or inspection methods as outlined in the following. 1.Each tank shall be tested for water tightness prior to backfill. 1.1.The tanks shall be filled 24 hours before the inspection to allow stabilization of the water level. Considering water absorption by the concrete, there may not be a change in the water level nor any water moving visibly into or out of the tank. Testing shall be supervised by the regulatory authority. Tanks exhibiting obvious defects or leaks may not be approved unless such deficiencies are repaired to the satisfaction of the regulatory authority. 2.The regulatory authority may allow two piece tanks, with the joint below the water level, to be backfilled up to 3 inches below the joint to provide adequate support to the seam of the tank. 3.Polyethylene or fiber glass tanks may be backfilled as per manufacturers' recommendations. 4.If ground water elevations inhibit the ability to visibly inspect the exterior of the tank, the tanks may be tested by their ability to exclude water. 5.Distribution and Drop Boxes. 5.1.Distribution and drop boxes (if used) should be installed level and the flow distribution lines shall be checked by filling the boxes with water up to the outlets. See Colorado Regulation No. 43 For Additional Details. Table 1 - Minimum Standards for Building Sewer, Effluent Sewer, and Distribution Pipe Materials Acceptable Building Sewer and Effluent Sewer Materials Per 43.9.D Type of Pipe Minimum Standard Polyvinyl Chloride (PVC)ASTM D-3034 OR BETTER Acceptable Distribution Pipe Materials Type of Pipe Minimum Standard Polyethylene (PE), Smooth Wall ASTM F-405 OR AASHTO M252 OR EQUIVALENT PVC ASTM D-2729 (c) OR BETTER Notes (a) Each Length of building sewer, effluent sewer, and distribution pipe shall be stamped or marked (b) American Society for Testing and Materials (c) Although perforated PVC, ASTM D-2729 is approved for absorption system application, the solid wall version of this pipe is not approved for any application. 29.Septic tanks may be divided into compartments provided they meet the following: 29.1.The volume of the first compartment shall equal or exceed two-thirds of the total required septic tank volume; 29.2.No compartment shall have an inside horizontal dimension less than 24 inches; 29.3.Inlets and outlets shall be designed as specified for tanks, except that when a partition wall is used to form a multi-compartment tank, an opening in the partition may serve for flow between compartments provided the minimum dimension of the opening is 4 inches, the cross-sectional area is not less than that of a 6 inch diameter pipe (28.3 square inches), and the mid-point is below the liquid surface a distance approximately equal to 40% of the liquid depth of the tank. 30.Scum storage volume shall consist of 15% or more of the required liquid capacity of the tank and shall be provided in the space between the liquid surface and the top of inlet and outlet devices. 31.Adequate access to the tank shall be provided to facilitate inspection, servicing and maintenance, and shall have no structure or other obstruction placed over it and shall conform to the following requirements: 31.1.Access to each compartment of the tank shall be provided through properly placed manhole openings not less than 20 inches in diameter, in minimum horizontal dimension or by means of an easily removable lid section. All access covers shall be designed and constructed in such a manner that they cannot pass through the access openings, and when closed will be child-proof and prevent entrance of surface water, dirt, or other foreign material, and seal the odorous gases in the tank. Concrete access covers for manhole openings shall have adequate handles. 32.Access to inlet and outlet devices shall be provided through properly spaced openings not less than 12 inches in minimum horizontal dimension or by means of an easily removable lid section.The purpose of this section is to diminish the possibility of onsite wastewater system failures by informing the owners of required periodic maintenance, servicing, and monitoring. More complex systems will require a higher level of operation and maintenance. 33.The system should be assessed after the first year of operation, and thereafter every three years. 34.For recommended tank servicing see Colorado Regulation No. 43. 35.Distribution and drop boxes, if provided, should be inspected at the same interval as the system or more often. 36.If corrective action is required see Colorado Regulation No. 43. 37.Maintenance of Septic Tanks. 37.1.Septic tanks shall be emptied before too much sludge or scum is allowed to accumulate and seriously reduce the tank volume settling depth. If either the settled solids or floating scum layer accumulate too close to the bottom of the outlet baffle or bottom of the sanitary tee pipe in the tank, solid particles will overflow into the absorption system and eventually clog the soil and ruin its absorption capacity. 37.2.A septic tank that receives normal loading should be inspected as indicated in Colorado Regulation No. 43 to determine if it needs emptying. Although there are wide differences in the rate that sludge and scum accumulate in tanks, a septic tank for a private residence will generally require emptying every three to five years. Actual measurement of scum and sludge accumulation is the only sure way to determine when a tank needs to be emptied. Experience for a particular system may indicate the desirability of longer or shorter intervals between inspections. 37.3.The tank should be completely emptied if either the bottom of the floating scum mat is within 3 inches of the bottom of the outlet baffle or tee or the sludge level has built up to approximately 12 inches from the bottom of the outlet baffle or tee, or the scum and sludge layers together equal 40% or more of the tank volume. All scum and solids should be washed out and removed from the tank. 37.4.If multiple tanks or tanks with multiple compartments are provided, care should be taken to ensure that each tank or compartment is inspected and emptied. 37.5.Septic tank wastes contain disease causing organisms and shall be disposed of only in areas and in a manner that is acceptable to local health authorities and consistent with state rules 37.6.Immediate replacement of damaged inlet or outlet fittings in the septic tank is essential for effective operation of the system. 38.Effluent screens or filters. 38.1.Remove the filter in a manner that prevents solids from passing to the absorption system. Wash the filter over the inlet side of septic tank. Replace the cleaned filter back into the outlet tee. 38.2.When the tank is empty, the interior surfaces of the tank should be inspected for leaks or cracks using a strong light. 38.3.A written record of all maintenance of the septic tank and absorption system should be kept by the owner of that system. 38.4.The functional operation of septic tanks is not improved by the addition of yeasts, disinfectants, additives or other chemicals; therefore, use of these materials is not recommended. 38.5.The advice of your regulatory authority should be sought before chemicals arising from a hobby or home industry or other unusual activities are discharged into a septic tank system. 38.6.Economy in the use of water helps prevent overloading of a septic tank system that could shorten its life and necessitate expensive repairs. The plumbing fixtures in the building should be checked regularly to repair any leaks that can add substantial amounts of water to the system. Industrial wastes and other liquids that may adversely affect the operation of the onsite wastewater system should not be discharged into such a system. Paper towels, facial tissue, disinfectant wipes, newspaper, wrapping paper, disposable diapers, sanitary napkins, coffee grounds, rags, sticks, and similar materials should also be excluded from the septic tank since they do not readily decompose and can lead to clogging of both the plumbing and the absorption system. 2024-031 APRIL 2024 OU T O F B O U N D S R A N C H TO Y B A R N ON S I T E W A S T E W A T E R TR E A T M E N T S Y S T E M THREADED PVC PLUG PLASTIC VALVE BOX 4" Ø PVC SEWER 45° PVC WYE 45° PVC BEND 4" Ø PVC PIPE THREADED PVC PLUG 4" Ø PVC SEWER 2-WAY CLEANOUT FITTING 4" Ø PVC PIPE PLASTIC VALVE BOX SHEET NUMBER: 4 / 4 PROJECT NUMBER: DATE: RE V I S I O N : DR A W N : DE T A I L S NATIVE BACKFILL TOPSOIL (CHAMBER SECTION)(END CAP VIEW) 4" pvc INLET INSTALL SPLASH GUARD UNDER INLET PIPE OR ANOTHER DESIGN FEATURE TO AVOID UNNECESSARY CHANNELING INTO THE TRENCH BOTTOM (EFFECTIVE LENGTH) TOP VIEW SIDE VIEW END VIEW INSPECTION PORT 2" diam.

Installation: Tuf-Tite Effluent Filters are designed to extend the life of your drainfield by preventing solids from leaving the septic tank. The filter fits into either a 4” or 6” Tee Baffle which in many cases is already attached to the outlet pipe. If a Tee Baffle is not installed, install as shown in Figure 2, allowing enough clearance from the end of the tank to permit easy filter access. 1.Insert the filter into the Tee Baffle with arrow on the top of the filter pointing toward the outlet pipe (as shown in Figure 1 and Figure 2). 2.Push down firmly until top of the filter seats into hub of the Baffle Tee. Maintenance: Tuf-Tite Effluent Filters will, under normal conditions, operate efficiently for several years or more before requiring removal and cleaning. It is suggested that the unit be cleaned every time the tank is pumped or at least every three years. 1.Do not use plumbing during filter cleaning. 2.Pull the filter straight out of the Tee. 3.Hose filter off, making sure that all solids fall back into the septic tank, not back into the Tee Baffle. 4.Replace filter as in installation instructions above.

Be sure to line up the locking pins on the top of both the chamber and endcap. 5. Insert the inlet pipe 2.5 inches into the opening on the endcap. 6. Lift and place the end of the next chamber onto the previ- ous chamber by holding it at a 45-degree angle. Line up the chamber end between the connector hook and locking pin at the top of the first chamber. Lower the cham- ber to the ground to connect the chambers. NOTE: When the chamber end is placed between the connector hook and locking pin at a 45-degree angle, the pin will be visible from the back side of the chamber. NOTE: The connector hook serves as a guide to ensure proper connection and does not add structural integrity to chamber joint. Broken hooks will not affect the structure or void the warranty. Contact Infiltrator Water Technologies 1-800-221-4436 for additional technical and product information. EXCAVATING AND PREPARING THE SITE NOTE: As is the case with conventional systems, do not install the systems in wet conditions or in overly moist soils, as this causes machinery to smear the soil. 1. Stake out location of trenches and lines. Set elevations of the tank, pipe, and trench bottom. 2. Install sedimentation and erosion control measures. Temporary drainage swales/ berms may be installed to protect the site during rainfall events. 3. Excavate and level 3-foot-wide trenches with proper center-to-center separation. Verify trenches are level or have pre- scribed slope. NOTE: Over excavate the trench width in areas where you are planning to contour. 4. Rake bottom and sides if smearing has occurred while excavating. Remove any large stones and other debris. Do not use the bucket teeth to rake the trench bottom. 5. Verify that each trench is level using a level, transit, or laser. PREPARING THE QUICK4 PLUS ALL-IN-ONE 12 ENDCAPS NOTE: The Quick4 Plus All-in-One 12 Endcap is compatible with the Quick4 Plus Standard and Quick4 Plus High Capacity chambers, and can be used on either end of the trench, depending upon the installer’s preference and configuration requirements. 1. With a hole saw drill a 4½-inch opening on front or side of endcap using center point marking (see illustration) as a guide. QUICK4 PLUS ALL-IN- ONE 12 ENDCAP DRILL LOCATIONS: 2. Snap off the molded splash plate locat- ed on the bottom front of the endcap. 3. Install splash plate into the appropriate slots below inlet to prevent trench bottom erosion. INSTALLING THE SYSTEM 1. Check the header pipe to be sure it is level or has the prescribed slope. 2. Set the invert height as specified in the design from the bottom of the inlet. 3. Place the first chamber in the trench. 4. Place the back edge of the endcap over the inlet end of Materials and Equipment Needed Quick4 Plus chambers Quick4 Plus All-In-One 12 Endcaps PVC pipe and couplings Backhoe Laser, transit or level Shovel and rake Tape measure Screwdriver or utility knife Hole saw 2-inch drywall screws* Screw gun* Small valve-cover box* 4-inch cap for Inspection port* *Optional These guidelines for construction machinery must be followed during installation. Avoid direct contact with chambers when using construction equipment. Chambers require a 12-inch minimum of compacted cover to support a wheel load rating of 16,000 lbs/axle or equivalent to an AASHTO H-10 load rating. Only drive across the trenches when necessary. Never drive down the length of the trenches. To avoid additional soil compaction, never drive heavy vehicles over the completed system. Quick4 Plus Standard and Quick4 Plus High Capacity Installation Instructions Quick4 Plus Standard and Quick4 Plus High Capacity chambers may only be installed according to State and/or local regulations. If unsure of the installation requirements for a particular site, contact the local health department. Like conventional systems, the soil and site conditions must be approved prior to installation. Conduct a thorough site evaluation to determine the proper sizing and siting of the system before installation. Quick4 Plus Standard Quick4 Plus High Capacity 1.

Swivel the chamber on the pin to achieve the proper direc- tion for trench layout. NOTE: The chamber allows up to 10-degree swivel in either direction at each joint. 8. Continue connecting chambers until the trench is completed. NOTE: As chambers are installed, verify they are level or have the prescribed slope. 9. The last chamber in the trench requires an endcap. Lift the endcap at a 45-degree angle and align the connector hook on the top of the chamber with the raised slot on the top of the endcap. Lower the end- cap to the ground and into place. NOTE: Place a few shovels of soil around the endcap to secure it during backfill. 10. To ensure structural stability, fill the sidewall area by pulling soil from the sides of the trench with a shovel. Start at the joints where the chambers connect. Continue backfilling the entire sidewall area, making sure the fill covers the lou- vers. 11. Pack down fill by walking along the edges of trench and chambers. NOTE: In wet or clay soils, do not walk in the sidewalls. 12. Proceed to the next trench and begin with Step 1. INSTALLING QUICK4 PLUS ALL-IN-ONE 12 ENDCAPS AS A MID-LINE CONNECTION 1.

With a hole saw, drill a 4½-inch opening on the end of the Quick4 Plus All-in-One 12 Endcap to cre- ate an invert at 0.5 inches. This will allow efflu- ent to fill both sides of the chamber line. 3. Snap off the molded splash plate located on the bottom front of the endcap. 4. Install splash plate into the appropriate slots below the inlet to prevent trench bottom erosion. 5. Place the back edge of the endcap over the inlet end of the first chamber. Be sure to line up the locking pins on the top of both chamber and endcap. 6. Insert connection pipe 2.5 inches into opening on endcap. INSTALLING INSPECTION PORTS Inspection ports may be installed on each of the chamber tops or on top of the Quick4 Plus All-in-One 12 Endcap. Endcap Inspection Port 1. With a hole saw drill the pre-marked area in the top of the chamber or endcap to create an open- ing based on pipe type. NOTE: Drill a 4½-inch opening on the Quick4 Plus High Capacity chamber and All-in-One Endcap to accommodate a 4-inch Schedule 40 pipe. Drill a 2½-inch opening on the Quick4 Plus Standard chamber to accommodate a 2-inch Schedule 40 pipe. 2. Set a cut piece of pipe of the appropri- ate length into the corresponding endcap’s inspection port sleeve. 3. Use two screws to fasten the pipe to the sleeve around the inspection port. 4. Attach a threaded cap or cleanout assembly onto the protruding pipe at the appropriate height. 5. A small valve cover box may be used if the inspection port is below the desired grade. COVERING THE SYSTEM Before backfilling, the system must be inspected by a health officer or other official as required by State and local codes. Create an as-built drawing at this time for future records. 1. Backfill the trench by pushing fill material over the chambers with a back- hoe. Keep a minimum of 12 inches of compacted cover over the chambers before driving over the system. NOTE: Do not drive over system while backfilling in sand. NOTE: For shallow cover applications, you must mound 12 inches of soil over the system before driving over it, and then grade it back to 6 inches upon completion. 2. It is best to mound several inches of soil over the finish grade to allow for settling. This also ensures that runoff water is diverted away from the system. 3. After the system is covered, the site should be seeded or sodded to prevent erosion. NOTE: If the system is for new home construction, it is important to leave marking stakes along the boundary of the system. This will show contractors where the site is located so they will not cross it with equipment or vehicles. 7. Swivel chambers. 9. Place endcap outlet end. 1. Drill endcap on side or top. 2.
