LLC Attn: Georgette Screen 320 W. Main Street Aspen. Colorado 81611 Job No. 414 250A Subject: Onsite Wastewater Treatment System Evaluation and Use Permit Inspection, 1518 West Buttermilk Road, Pitkin County, Colorado. Dear Ms. Screen: As requested, Hepworth-Pawlak Geotechnical, Inc. (HP Geotech) has evaluated the capacity of the existing Onsite Wastewater Treatment System (OWTS) and performed a Use Permit Inspection for continued use of the system. Our set -vices were performed in accordance with our Professional Services Agreement to West Buttermilk Holdings VIII, LLC dated October 1, 2014. Our findings are presented below. HP Geotech previously prepared an Individual Sewage Disposal System Design for the property in our report dated Febnrary 8, 2006 and performed an As -Built Evaluation for the construction of the system in our report dated December 6, 2006, Job No. 405348. Site Conditions and Construction: The original OWTS on the property was permitted for a seven bedroom residence. The owners are currently in the process of constructing a bunk room and two additional bathrooms in the former garage on the property. We have assumed two additional bedrooms will be added to the OWTS (nine bedrooms total) due to the bunkroom construction. OWTS Calculations: The current OWTS consists of two 2,000 gallon single compartment septic tanks followed by a 1,000 gallon dose tank equipped with an effluent pump. The 4,000 gallons of septic tank settling capacity in the first two tanks is suitable for 10 bedrooms per Table 6,28-6 of the current Pitkin County OWTS Regulations which states: * 3 bedrooms = 1,200 gallon minimum settling capacity * Each additional bedroom = (2 persons)* (100 gpd)*(#bedrooi-ns)*(2.0 retention tactor) The existing soil treatment area consists of two soil treatment area beds separated into three zones by an automatic distribution valve. A total of 239 Infiltrator Quick 4 Standard chambers were installed in the two beds. Per current sizing specifications, each chamber is allowed 12 square feet of treatment area capacity or 2,868 square feet of total treatment area. The soils at the site were evaluated using accepted methods at the time instead of the soil Glenwood Springs 970-94.5-7988 * Parker 303-841.7119 * Colorado Sprigs 719-633-5562 (XtoTe"ria Page 2 treatment evaluationNwAt is now required. Based on the percolatiAlst data (23 MPI average) and profile pit log we have estimated that the soils at the site would be a Soil Type 2 or 2A (Sandy Loam) based on Table 6.28-7 of the current OWTS Regulations. For the purposes of this evaluation, we have assumed a more conservative Soil Type 2A which equates to a Long-Term Acceptance Rate (LTAR) of 0.5 gallons per square foot per day. Flow= 2 persons*#bedrooms* 100 gallons/person/day (living area > 6,000 square feet) Flow = 2 persons* 10 bedrooms* 100 gpd = % allons per day Treatment Area = F low/LTAR -ZPMO Treatment Area = 2,000 gpd/0.5 gal/Qday = 4,000 square feet Reduction Factor for Chambers = 0.7 Treatment Area with Reduction = 4,000 square feet * 0.7 = 2,800 square feetn 'z -al r, �Z Based on the estimated LTAR and existing soil treatment area square footage, the system is suitable for a maximum of 10 bedrooms per current regulations. Therefore, based on out- evaluation urevaluation the system as currently constructed is suitable for the additional capacity of the proposed bunk room. Soil treatment area calculations for a 10 bedroom residence are as follows. OWTS Use Permit Inspection: Per Section 6.28.020.B.2 of the Pitkin County OWTS Regulations.. a Use Permit inspection is required for any OWTS where a building permit will be required for the property. A representative of HP Geotech performed an initial inspection of the OWTS on the property on October 9, 2014. The septic and dose tanks were pumped and the conditions of the tanks were inspected. The tanks were sound, however, the inlet bailie to the first tank had fallen off and was resting in the bottom of the tank. Repair of this item was recommended to the owner. We also performed a pump operation test and found that a fitting in the pump discharge line was cracked causing, which caused effluent to discharge into the pu►i►p vault. The crack did not allow the system to fully pressurize and only limited effluent was reaching the soil treatment area. The alarm was also not functioning properly. We recommended repair of both of these items. We returned to the site oil October 24, 2014. The three previous deficiencies were inspected and had been repaired by a contractor hired by the owner. A pump operation test was performed. With the system repaired, we were able to verify operation of the automatic distribution valve and inspect the infiltration of effluent in the soil treatment area through the inspection ports. No deficiencies were found within the soil treatment area. The automatic distribution valve was operating properly; however, it was not adequately protected. The valve box lid would not close properly leaving the valve susceptible to freezing. We Job No. 414 250A GerSbsch West Buttermilk Holdings V111. LLC October 30. 2014 Page 3 recommend the top of the valve be housed in an enclosure that provides at least 2 feet of soil cover between the top of the valve and the enclosure lid. The lid should be insulated with 2 inch thick blueboard and the area surrounding the valve should be insulated with loose fill insulation such as perlite. A 2 feet high section of 24 inch diameter septic tank riser with a securable lid is often used for distribution valve assembly protection. The lid should be visible from ground surface. We also recommend heat tape around the valve and inlet and outlet piping for additional freezing protection. Based on our evaluation following repairs, the OWTS was operating as designed. Although the system is currently operating, freezing conditions could damage the automatic distribution valve and piping if not corrected in the near future. A copy of our OWTS Use Permit Inspection Form for the property is provided as an attachment. Limitations: We have conducted this study in accordance with generally accepted engineering principles and practices in this area at this time. We make no warranty either expressed or implied. The conclusions and recommendations submitted in this report are based upon our review of the existing OWTS Design and As -Built, our site inspections. the proposed construction and our experience in the area. Site grading or other site modifications could alter the effectiveness of the OWTS. Please feel free to contact its if you have any questions or require additional information.
