Our observations and recommendations are presented in this report. The services are supplemental to Kumar & Associates agreement for professional services to you dated November 30, 2020. We previously designed the new OWTS for the residence as submitted in our report dated February 8, 2021, Project No. 20-7-734. The system was designed for four bedrooms. The system was installed by Paulsen Construction. We performed our evaluations on February 23 and March 2, 2021. The OWTS components observed included: a portion of the sewer line, the cleanout, septic tank, effluent line, distribution box and soil treatment area (STA) and the locations of these components. The installation and locations of the system components were verified as shown on Figure 1. Pictures of the OWTS components made during the site visit are included with this report. The distance locations to the septic tank shown on Figure 1 were made by taping. The previous septic tank was abandoned in accordance with Eagle County regulations. The existing sewer line to near the tank was inspected and scoped by others and the video sent to us, and was determined to be in acceptable condition and is used as part of the new OWTS. The distribution box was changed from the designed Tuf-Tite 4-hole distribution box to a Polylok 6-hole distribution box. This change was deemed acceptable to us. It is our opinion that the OWTS was installed in general conformance with the above referenced design. The observations and recommendations presented above are based on our site observations and our experience in the area. We make no warranty either express or implied.

Project No. 20-7-734 INTRODUCTION This report provides the results of an onsite wastewater treatment system (OWTS) design for the existing residence located on Lot 219, Eby Creek Mesa, 756 Eby Creek Road, Eagle County, Colorado. The purpose of the report is to provide design details for the OWTS in accordance with the 2018 Eagle County Environmental Health Department Onsite Wastewater Treatment System Regulations and the Colorado Department of Public Health and Environmental Regulation #43. The services were performed in accordance with our agreement for professional services to George Redford dated November 30, 2020. PROPOSED CONSTRUCTION The existing residence is a single-family structure located on the lot as shown on Figure 1. The residence has four bedrooms. The existing OWTS has apparently failed and will be replaced. The OWTS will be designed for a total of four bedrooms. The proposed soil treatment area (STA) for the OWTS will be located to the south of the residence as shown on Figure 1. Water service is provided by an onsite well far away from the proposed STA. If proposed construction is different than that described, we should be contacted to re-evaluate our design recommendations. SITE CONDITIONS The site is occupied by a single family, one-story residence over a walkout out basement. The terrain is generally gently to moderately sloping down to the west towards Eby Creek. Eby Creek trends north to south in the west portion of the lot and is located as shown on Figure 1. The current STA is located in a gravel parking area, and generally to the east of the new STA location. Vegetation consists of conifers and cottonwood trees with sage brush and grass. SUBSURFACE CONDITIONS The field exploration for the OWTS was conducted on January 15, 2021. Two profile pits (Profile Pits 1 and 2) were excavated with a backhoe at the approximate locations shown on Figure 1 to evaluate the subsurface conditions for the planned new soil treatment area for the OWTS. The pits were logged by a representative of Kumar & Associates. Logs of the profile pits are provided below. - 2 - Kumar & Associates, Inc. Project No. 20-7-734 Log of Profile Pit 1 Depth USDA Classification 0-2’ TOPSOIL; organic Loam, firm, moist, dark brown. 2’-8’ SANDY LOAM; moderately blocky structure, stiff/loose, moist, grayish brown, gypsiferous. • Disturbed bulk sample obtained from 6 to 7 feet. • Bottom of pit @ 8 feet. • No groundwater or redoximorphic features observed at time of pit excavation. Log of Profile Pit 2 Depth USDA Classification 0-½’ MAN-PLACED FILL; gravel driveway, firm, slightly moist, mixed brown. ½’-8’ SANDY LOAM; moderately blocky structure, stiff/medium dense, slightly moist, tan, gypsiferous. • Disturbed bulk sample obtained from 3 to 4 feet. • Bottom of pit @ 8 feet. • No groundwater or redoximorphic features observed at time of pit excavation. The soils encountered in profile pits, below about 2 feet of organic topsoil in Profile Pit 1 and ½ foot of gravel fill in Profile Pit 2, consisted of Sandy Loam down to the pit depths of 8 feet. Hydrometer and gradation analyses were performed on a disturbed bulk sample of the soils from Profile Pit 2 from 3 to 4 feet depth with the results provided on Figure 2. The tested sample (minus No.10 size sieve fraction) classifies as Sandy Loam per the USDA system. No free water was encountered in the pits nor indications of seasonal high groundwater were observed at the time of the pit excavations. Based on the subsurface conditions and laboratory testing, the soils at the STA have been classified as Type 2 per State regulations, which equates to a long-term acceptance rate (LTAR) of 0.60 gallons per square foot per day. OWTS ANALYSIS Based on the site conditions and profile pit evaluations, the evaluated area should be suitable for a conventional infiltration disposal system. There is adequate elevation difference from the ground floor of the residence down to the STA for gravity flow of the sewer effluent. The STA will consist of chambers in a trench configuration based in the Sandy Loam soils. The STA will be sized for four bedrooms (seven persons) and an average daily flow of 75 gallons per person, and an LTAR of 0.60 gallons per square foot per day for the natural Sandy Loam soils. - 3 - Kumar & Associates, Inc. Project No. 20-7-734 The effluent will gravity flow from the residence to a new septic tank for primary treatment and then gravity flow to the STA for dispersal and final treatment. The STA will consist of three trenches with Infiltrator Quick 4 Plus Standard chambers. Equal distribution will be provided to the chambers and trenches by a distribution box. A 50 feet minimum setback is required for the STA from Eby Creek, located to the west of the STA. Based on site plan measurements, the STA will be approximately 50 feet from the creek. A 10 feet minimum setback is required from the concrete slab, as shown on Figure 1, to the STA. There are no known water supply lines in the vicinity of the proposed STA. The required setback to the water supply line from the septic tank is 10 feet, 5 feet for sewer and effluent lines, and 25 feet from the STA. We should be notified for additional recommendations if the water supply line is within these minimum setbacks. DESIGN RECOMMENDATIONS The design recommendations presented below are based on the proposed construction, the site and subsurface conditions encountered and our experience in the area. A layout of the proposed OWTS components is provided on Figure 1. If conditions encountered during construction are different than those that are described in this report, we should be contacted to re-evaluate our design recommendations. SOIL TREATMENT AREA • The STA will consist of three trenches with 18 Infiltrator Quick 4 Plus Standard chambers placed in each trench (54 chambers total) in the native soils. Equal distribution will be provided to the trenches by a distribution box. • The STA was sized based on an LTAR of 0.60 gallons per square feet per day. • Each chamber was allowed 12 square feet of area. A 30% reduction of the STA size was applied for use of Infiltrator chambers in a trench configuration. The total STA design size is 648 square feet. Soil treatment area calculations are shown on Figure 3. • A minimum of four feet of undisturbed soil between trenches is required. • Trench cut depths should be a maximum of 3 feet deep. • The trenches should be oriented along ground contours to minimize soil cut and cover. • The base and sidewalls of the trench excavations should be scarified prior to the chamber placement. • A minimum of 12 inches and a maximum of 24 inches of cover soil should be placed over the chambers. - 4 - Kumar & Associates, Inc. Project No. 20-7-734 • Backfill should be graded to deflect surface water away from the STA and should be sloped at 3 horizontal to 1 vertical or flatter. A swale to divert surface water flow away from the STA may be needed along the upslope side. • Disturbed soil should be re-vegetated as soon as possible with a native grass mix. No trees, shrubs or other plants with deep roots should be planted on or near the STA as this may damage the system piping. • Four-inch diameter inspection ports should be installed vertically into the knockouts provided in the chamber end caps. Install ports at each end of the trench. The inspection port piping should be screwed into the top to the chambers and should not extend down to the ground surface inside the chambers. The inspection ports should extend at least 8 inches above the finished ground surface or be protected in a valve box at finished grade. • The STA must be a minimum of 50 feet from Eby Creek. • The STA must be a minimum of 25 feet from any potable water supply lines. • The STA must be a minimum of 10 feet from any slab-on-grade structures. • A plan view of the STA is presented on Figure 4 and a cross section of the STA is presented on Figure 5. OWTS COMPONENTS Recommended OWTS components provided below are based on our design details and our experience with the specific component manufacturers. Equivalent components may be feasible but need to be approved by us prior to construction. Septic Tank • A Valley Precast 1,250 gallon, two-chamber septic tank should be used for primary treatment and dosing to the STA. The tank will be located just west of the existing tank which will be abandoned. A detail of the tank is provided as an attachment. • An effluent filter should be installed in the tank outlet tee. • The tank must be a minimum of 5 feet from the residence. • The tank must be a minimum of 10 feet from any potable water supply lines. • The tank must be minimum of 50 feet from Eby Creek. • The tank must be set level. The excavation bottom must be free of large rocks or other objects that could damage the tank during placement. A road base or gravel bedding material may be needed to prevent tank damage during placement and act as a leveling course. - 5 - Kumar & Associates, Inc. Project No. 20-7-734 • The tank lids must extend to final surface grade and made to be easily located. • Install the tank with 2 feet minimum cover soil for frost protection. Maximum tank soil cover is 4 feet. • The existing septic tank should be abandoned per Eagle County regulations. Sewer Pipe • The location and condition of the existing sewer line to the tank should be evaluated at the time of construction and replaced as needed. • The sewer line to the septic tank should not be less than the diameter of the building drains and not less than 4 inches in diameter. • The sewer pipe should have a rating of SDR35 or stronger. Schedule 40 PVC pipe is required beneath any driveway surfaces. • The sewer pipe should be sloped between 2% to 4% to help limit disturbance of solids in the tank and potential sewage bypass of the first chamber of the tank. If a steeper slope is needed, this can be accomplished with vertical step-downs in the sewer line. • A minimum 36 inches of cover soil should be provided over the sewer pipe. Paved areas, patios or other areas without vegetative cover may be more susceptible to frost and we recommend 48 inches of soil cover over the sewer pipe in these areas, and the pipe be insulated on top and sides with 2-inch-thick blue foam insulation board. If adequate soil cover is not possible, we should be contacted for re-evaluation prior to installation. • The sewer pipe should be bedded in compacted ¾-inch road base or native soils provided that the native soils contain no angular rocks or rocks larger than 2½ inches in diameter to help prevent settlement of the pipe. Sags in the pipe could cause standing effluent to freeze and damage the piping. • Install cleanout pipes within 5 feet of the building foundation, where the sewer pipes bend 90 degrees or more and every 100 feet of sewer pipe. • All 90-degree bends should be installed using a 90-degree long-sweep or by using two 45-degree elbows. • The sewer line location shown on Figure 1 is considered conceptual. We assume that there will be only one sewer line exiting the residence. It is the responsibility of the owner/contractors to locate all sewer line exit locations and connections to the septic tank. We should be notified if there are other sewer lines exiting the building. Effluent Transport Piping • The effluent transport pipe should be 4-inch diameter SDR35 piping sloped at a 2% minimum to flow from the septic tank to the distribution box and from the distribution - 6 - Kumar & Associates, Inc. Project No. 20-7-734 box to each trench. Piping should extend at least 6 inches into the top knockout provided in the Infiltrator end caps and be screwed in place. Splash plates should be installed beneath the inlet piping to help limit scouring of the infiltrative soil surface in the chambers. • The effluent transport pipe should be bedded in compacted ¾-inch road base or native soils provided that the native soils contain no angular rocks or rocks larger than 2½ inches in diameter to help prevent settlement of the pipe. Sags could cause standing effluent to freeze and damage to the piping. • A minimum 18 inches of cover soil should be provided over the effluent transport pipe. Paved areas, patios or other areas without vegetative cover may be more susceptible to frost. We recommend 48 inches of soil cover over the effluent pipe and insulation with at least 2 inches of rigid foam insulation in these areas. If adequate cover soil is not possible, we should re-evaluate the condition prior to installation. • Schedule 40 PVC pipe is required underneath driveway surfaces and should be provided with at least 48 inches of soil cover, and be insulated on top and sides with 2-inch-thick rigid foam insulation board. • All 90-degree bends should be installed using a 90 degree long-sweep or by using two 45-degree elbows. Distribution Box • The distribution box will be used to equally divide effluent flow between the trenches. We recommend the Tuf-Tite 4-Hole Distribution Box since it is easily accessible from ground surface for maintenance. A copy of the distribution box detail is provided as an attachment to this report. • The distribution box outlet pipes should be equipped with Tuf-Tite speed levelers for ease of initial setup and adjustment over time. • The distribution box should be a minimum of 18 inches below grade with risers and an access lid at or above grade. • The distribution box must be accessible from ground surface for inspection and maintenance per the State guidelines. • The effluent line from the septic tank should be directed downward into the distribution box with a 90-degree elbow inside the box. • The distribution box must be installed level on a compacted road base subgrade to ensure equal effluent distribution. If settlement of the distribution box occurs, unequal effluent distribution may take place which could cause hydraulic overload of one of the trenches - 7 - Kumar & Associates, Inc. Project No. 20-7-734 and potential failure. The distribution box should be monitored periodically, and the speed levelers should be adjusted as necessary for levelling. • The ground surface above and around the distribution box should be graded to drain away surface water to prevent standing water near the distribution box which could freeze or cause settlement. OWTS OPERATION AND MAINTENANCE The OWTS will require periodic inspection and maintenance to function properly. A properly designed, installed and maintained system can greatly increase its lifespan. The level of maintenance will vary depending on the complexity of the system and water use habits of the residents. We recommend that an OWTS Operation and Maintenance (O&M) Manual be developed. Depending on the complexity of the system, a contract with an OWTS maintenance provider may be prudent. Below are some basic recommendations for the OWTS O&M. OWTS HOUSEHOLD OPERATION • Use of high efficiency water fixtures is recommended to decrease the hydraulic load on the OWTS system. • Fix plumbing leaks immediately as this may cause a hydraulic overload of the soil absorption system. • Do not irrigate the area on top of or directly upgradient of the soil absorption field as this may cause a hydraulic overload. • Do not dispose of household waste down drains as this may clog or damage OWTS components. Examples of household waste includes: dental floss, cotton swabs, coffee grounds, paper towels, feminine products and many other kitchen and bath items. • Use of kitchen garbage disposals is not recommended. If a garbage disposal is utilized, kitchen wastewater should be screened thoroughly. Many kitchen solids are not decomposed in the septic tank and may cause increased tank pumping frequency. • Do not dispose of household chemicals, greases, oils, paints, hot tub water or water softener backwash in household drains. A separate drywell, if feasible, may be necessary for hot tub water or water softener backwash disposal. • Limit the use of bleach as this may harm useful bacteria in the septic tank and soil absorption system. • Liquid dishwasher and clothes washer detergent is recommended for households served by an OWTS. Clay substances used as fillers in powder detergents may result in clogging of the soils absorption system. - 8 - Kumar & Associates, Inc. Project No. 20-7-734 • The effluent in septic tanks can freeze during extended periods of non-use in cold weather. We recommend that a tank heater be installed in this system to help prevent freezing. OWTS MAINTENANCE • Inspect the septic tank, distribution box and STA at least annually for problems or signs of failure. • The effluent filter for the tank should be cleaned at least annually by spray washing solids into the first chamber of the septic tank. • The septic tank should be pumped and cleaned every 3 to 5 years depending on use. Longer pumping intervals may increase the amount of solids that reach the STA, which may shorten its life span. • Pumping of the septic tank should take place when the level of the sludge and scum layers combined take up 25 to 33% of the capacity of the first chamber of the tank. OWTS CONSTRUCTION OBSERVATION The Eagle County Environmental Health Department requires that the designer of the system provide a record drawing and certification of the OWTS construction (As-Built inspection). We should be provided with at least 48-hour notice prior to the installer needing the inspections. Prior to issuance of our certification letter, we require observation of all system components prior to backfill. The number of site visits required for the inspection will depend on the installer’s construction schedule. LIMITATIONS We have conducted this design in accordance with generally accepted engineering principles and practices in this area at this time. We make no warranty either expressed or implied. The recommendations provided in this report are based on the site conditions, profile pit evaluations and soil texture analysis, the proposed construction and our experience in the area. Variations in the subsurface conditions may not become evident until excavation is performed. If conditions encountered during construction appear different from those described in this report, we should be notified so that re-evaluation of the recommendations may be made. This report has been prepared for the exclusive use by our client for design purposes. We are not responsible for technical interpretations by others of our information. As the project evolves, we should provide continued consultation and field services during construction to review and 756 Kumar & Associates SILT COBBLES COARSE GRAVEL MEDIUMMEDIUMV.
