Not in use at the time of the inspection.* *If the OWTS was not in use at the time of the inspection, it is recommended that the system be re-evaluated when it is in use for a more accurate evaluation of the system. System Records: Permit #: 98067 Date of Issuance: 10/7/1998 Date of Final Approval: 8/22/2000 # of Bedrooms or fixtures served by OWTS: This system was originally designed for 4 bedrooms but when sizing is compared to new regulations the system is large enough to accommodate 5 bedrooms. Operational Status: According to the inspectors observations at the time of the inspection the system was functioning as designed. Both inlet and outlet tees were in place and tank was accessible from grade. The distribution box was not accessible for inspection. The sand bed area did not show any signs of failure such as surfacing effluent. Inspector Recommendations: Add an effluent filter to the outlet tee of the septic tank if possible. Locate distribution box and bring access to grade for maintenance. Department Recommendations: Annual maintenance. Issuance of this OWTS Use Permit is based solely on the conditions observed and reported by the inspector to the Department on the date of the inspection(s) and on Department records at the time of permitting. The issuance of this permit does not constitute a guarantee, warranty, or representation by the Department that the system will operate properly or will not fail or that the system will not be subject to future enforcement action to correct non-compliant conditions. Estimated capacity of the system has been listed on the permit and we recommend that you monitor and/or meter water use to prevent overuse and possible failure. 0020.2018.POWU 0020.2018.POWU CBO Inc. 33 Four Wheel Drive Road Carbondale, CO 81623 cell) 970-309-5259 carla.ostberg@gmail.com April 2, 2018 Scott DeWind scott@compass.cm.co Onsite Wastewater Treatment System (OWTS) Use Permit Inspection 111 Little Texas Lane Pitkin County, Colorado Scott, As requested, CBO Inc. performed an Onsite Wastewater Treatment System (OWTS) Use Permit inspection at 111 Little Texas Lane, Woody Creek, Colorado on March 8, 2018. The legal description of the 0.52-acre property is Lot 10, Little Texas Subdivision. The permit and record drawing were provided by Pitkin County Environmental Health Department (Parcel ID # 2463-164-01-011). The subject OWTS consists of one 1500-gallon1 two-compartment septic tank. Effluent gravity flows to a distribution box and then to 10 rows of 8 ‘Standard’ Infiltrator® chambers on a sand filter. Individual Sewage Disposal System Permit 98067 documents this system. The permit received final approval on August 22, 2000. The system was sized to accommodate 4 bedrooms. Previous inspections were conducted in 2012 and 2014. OWTS Use Permits 0029.2012.POWU and 0010.2014.POWU were issued after the these inspections were conducted. Three feet of risers bring the septic tank manhole lids to grade. Both inlet and outlet tees were present. We typically recommend adding an effluent filter; however, the outlet tee is tucked under the lid of the septic tank making the installation difficult without extending the tee. The septic tank was pumped by RotoRooter on January 12, 2018. Since that time, occupancy has been intermittent. We ran water through the septic tank for approximately 30+ minutes and normal flow through was observed. They also added a “bio kit treatment”. The product is distributed through Pro Pump (website screenshot and RotoRooter invoices enclosed). The distribution box was not accessible from grade. We recommend locating the distribution box and brining access to grade for inspection and maintenance. The soil treatment area (STA) is covered with a flagstone patio. Good vegetation is recommended above an absorption area; however, notes from Pitkin County indicate the county was aware of the patio when they approved the system. One observation port is present. The bottom of the absorption area is approximately 6-feet below grade and it was dry. There was no evidence of surface saturation or failure at the time of our inspection. We also walked the area below the STA and found no evidence of surface saturation or failure. The addition of a 5th bedroom is proposed. There will be less than 6000 square feet of living area. Table 1 below compares the size of the existing OWTS to sizing requirements for 5 bedrooms with less than 6000 square feet of living area under current OWTS regulations. 1 Pitkin County ISDS Permit indicates a 2000-gallon septic tank was specified; however, RotoRooter’s invoice notes 1500-gallons were pumped. 0020.2018.POWU Table 1 Existing 2014 OWTS Regulations Tank Size 1500-gallon tank, two- compartment septic tank Min. 1500 gallons Soil Treatment Area Gravity Fed Sand Filter with Chambers Infiltrative area: 10 rows of 8 ‘Standard’ chambers = 1500 SF Infiltrative area: Min. 1125 SF using 0.8 gal/SF 2014 OWTS Regulation Calculations 75 GPD x 2 persons/bedroom x 5 bedrooms = 750 GPD LTAR = 0.8 (Soil Type 1 Sand) 750 GPD / 0.8 gal/SF = 937.5 SF infiltrative area 937.5 SF x 1.2 (gravity, bed) x 1.0 (no reduction for chambers) = 1125 SF In summary, the system appears to be sized to accommodate a 5-bedroom residence with less than 6000 square feet of living area under current OWTS Regulations. We are using Soil Type 1 (Sand) based on the fact that the design is a sand filter; however, no information on the depth of sand was available in the permit or as-built drawing. Recommendations: • Locate distribution box and bring access to grade.

Operational Status: According to the inspector's observations, the system was functioning properly at the time of inspection. The 2000 gallon tank was watertight and in good working condition with both inlet and outlet tees in place. The tank was not easily accessible because risers were about a foot below grade. The tank flows to a distribution box that was not accessible from grade to a sand filter bed with gravelless chambers. The absorption area did not show any signs of failure and there was no standing liquid in the observation ports. Inspector Recommendations: Install effluent filter and add risers to the tank to bring them to grade. Department Recommendations: The department recommends making the distribution box accessible from grade.
