The Owner is Gerard. The parcel is 35 + Acres in the Gypsum Creek Valley. References to Regulation 43 (Reg 43) refers to the requirements of the Colorado Water Quality Control Commission's Regulation No. 43 _ On -site Wastewater Treatment System Regulation, 5 CCR 1002-43, effective May 15, 2018, or as adopted by Eagle County Environmental Health (EH), and all other Eagle County Land Use Regulations that may apply. FACILITIES SERVED The OWTS will serve a new four (4) bedroom home and is rural residential. No other structures will utilize the new OWTS. No change in zoning is proposed. SITE CONDITIONS Two (2) 8 feet deep profiles holes were dug in August 2019, and confirmed no limiting layers existed by digging with a backhoe adjacent to the STA. Profile holes depict a very sand silty loam soil, reddish with cobbles, more single grain, with no visible clay. Upon wetting, it was not plastic, some shape, but fell apart (structureless). Soil of this character has a percolation rate of 7-12 minutes / inch. No groundwater was revealed and no sign of mottling of soil profile. remove all elements as noted on the original permit. Excavator should perform exploratory digging as needed. SITE CONDITIONS Two (2) 8 feet deep profiles holes were dug in August 2019, and confirmed no limiting layers existed by digging with a backhoe adjacent to the STA. Profile holes depict a very sand silty soil, tan -reddish brown, more single grain, with no visible clay. Upon wetting, it was not plastic, some shape, but fell apart (structureless). Soil of this character has a percolation rate of 7-12 minutes / inch. No groundwater was revealed and no sign of mottling of soil profile. Other locations of the lot were explored for the soil treatment area (STA), but rejected due to insufficient setbacks or risks of impacts by inhabitants. DESIGN FACTORS Reductions in the design flows included: Chamber Reduction = 30% (Factor = .70) Dosing Reduction = 20% (Factor = .80) Due to the obtainable specified concrete sand, a Long -Term Acceptance Rate (LTAR) = 0.8 GAL/Day/sf was utilized (CDPHE, Table 10-1). See attached Figure 4 Treatment Sand Specifications by Old Castle. The STA area chosen was evaluated to be the best location away from buildings, land features, water features and the adjoining lot dwelling to the north. RESERVE STA A reserve STA is an area reserved for the condition and likeliness of the failure of the current designed OWTS. Inherently the STA - leach field is a "progressive failure" component, and its life span is based on both environmental and human factors affecting the biological treatment of the effluent. As shown on the site plan SS1, the Reserve Area is just to the west of the proposed STA. A future reserve area would likely adhere to the minimum separation between features, but the owner should be aware of the reserve area with respect to animal grazing and other buildings encroaching on it. 1,500 GAL 2-COMPARTMENT SEPTIC TANK Visible and audible alarms to be tested prior to being connected to Contact Valley Precast at (719) 395-6764 for service and warranty E Page proposed final grade of the tank is subject to the existing sewage pipe exiting the foundation design by others, final grading of lot, and keeping above potential shallow flooding. Pipe invert elevations are equally subject to the final grading and should be established by a qualified surveyor. INSTALLATION All work required to be by a licensed and experienced septic installer in Eagle County. Owner advised to obtain contractor references. The house to septic tank connection to be fitted with one (1) "Fernco/Shear Guard" coupler near house exit to prevent breakage of pipe due to tank or soil movement. Tank baffles to be installed per Reg # 43, or by manufacturer (inlet tee above liquid surface 5 inches min, min 8 inches below liquid surface. Outlet tee shall extend 14 inches below the outlet invert and includes a bio filter (effluent screen). No over excavation allowed for septic tank or chambers. Install septic tank level on 6 inches of 3/4' screen rock over 140 N filter fabric. All pipe to be SDR 35 solvent -weld joints (gasketed push -on fittings not recommended due to the tree roots). Connections between the tank and risers shall be sealed and watertight. Backfill and compact the pipe trench, septic tank and risers to manufacturer specifications. Use CDOT Class 6 Road base or 3/4-inch screen rock for "shedding" all pipe to prevent settlement. Install 2-inch rigid insulation above pipe at all areas of motorized traffic or potential frost if pipe depth is less than 4 ft. Grade to surroundings, allowing for settling. Risers to be to grade with tamperproof lids. SPECIAL GRADING and EARTH WORK Due to the steep grade of the south facing hill of the residence, and the final STA on more level grades, it is recommended to not impact vegetation with the OWTS piping and to make manufacturer approved bends in the pipe and chambers to fit within the restrictions on site. Grading shown on SS1 is approximate and subject to field conditions. Additional fill may be required. Use only soil free of gravel or boulders as needed for trench embankment and grading. REQUIRED MAINTENANCE Maintenance annually or as needed includes, but not limited to: 1) Cleansing of the septic tank bio-filter: annually or AS NEEDED. 2) Pumping of septic tank (2-3 years per Regulations). 3) Prevent all disturbance to the surface treatment area, includii 3 Page humans and animals, and no non -natural watering. Fencing advised. SEPTIC TANK DIMENSIONS TO FACILITIES Separation to facilities is critical and the licensed installer is required to meet all minimum distances between components of the On -Site Wastewater Treatment System according to Table 7-1, Section 43.7 of Reg 43. Survey by others recommended. CONSTRUCTION DEVIATIONS CONFLICTING TO DESIGN OR THE REGULATIONS Notify the engineer of any deviations in the in -situ conditions or limitations to construct the OWTS in accordance with the design drawings, this addendum, or Reg #43 prior to commencement of the work. All work to conform to the manufacturer's recommendations, including but not limited to: pipe installation, Valley Precast components, Infiltrator Chambers, inspection ports, electrical and all controls. This OWTS design is not responsible for the construction means and methods of all others performing the work, including their responsibility to meet any and all federal state and local codes and regulations, including health and safety requirements for all others. ENGINEERING INSPECTION REQUIRED The engineer shall be notified of all work, 48 hours in advance, to allow observation of the work meeting the design drawings prior to backfill. Pictures are not a substitute to engineering inspection — regardless of conditions or hardship(s). No substitutions or changes allowed without prior engineer approval. RECORD DRAWINGS REQUIRED OWTS contractor and electrical contractor to provide engineer record drawings of all work, including bearings and 3-point ties to benchmark or other facilities. PLS survey may be required if record drawing does not accurately reflect the as -built condition. Provide record drawings to engineer a maximum of 30 days following completion to allow for final certification process and submittals to Environmental Health. 4 1 Page Page | 1 OWTS-017114-2019 RES– 017360-2019 WORK FOR CLAYTON AND CASSIE GERARD OBSERVATION PICTURES, COMPLETE MARCH 2020 1348 DAGGETT LANE, EAGLE COUNTY, CO 81637 PN 2111-192-00-005 CONSTRUCTED BY Brock Civil, LLC LIC # OWSTPL-000027 -2019 ONE PIECE CONCRETE 1,500 GALLON SEPTIC TANK BY VALLEY PRECAST SET ON 6 INCHES WASHED ROCK, LEVEL.
