Oak Way Garfield County, Colorado Scott, As requested, CBO Inc. performed an Onsite Wastewater Treatment System (OWTS) inspection at 308 S. Oak Way, Glenwood Springs, Colorado on January 14, 2021. The legal description of the 2.48-acre property is as follows: Section: 22 Township: 7 Range: 89 Subdivision: OAK MEADOWS SUB. 1ST. Block: 1 Lot: 9 Parcel ID: 2395-221-01-009 No records were available from Garfield County Environmental Health Department. The house was originally constructed in 1974 according to the Garfield County Assessor's website. The OWTS was replaced Rock Hawg Contruction, Inc. out of Meeker, Colorado in 2014. No permits were obtained. The subject OWTS consists of 1250-gallon, two -compartment concrete septic tank followed by a soil treatment area (STA) comprised 63 'ARC' ADS chambers, according to the invoice from Rock Hawg Construction. 'ARC' ADS chambers, formerly referred to as "Bio-diffusers" measure 3' x 5'. The septic tank, located to the southwest of the residence, was uncovered at the time of our inspection. We recommend risers be added to the manholes to bring access to grade. Eighteen inches of risers have been ordered from Tim Copeland. Both inlet and outlet tees were present. Liquid levels in the septic tank appeared normal at the time of our inspection. We recommend a full size Orenco® Biotube Effluent Filter be installed on the outlet tee. If installed, this filter must be cleaned annually, or as needed. There was snow cover over at the time of our inspection. The STA is likely to the west of the septic tank. No inspection ports were observed. We walked the approximate area and found no evidence of surface saturation or failure at the time of the inspection. This evaluation is not a guarantee of future system performance. Recommendations: • Add risers to manhole lids to bring access to grade. • Install effluent filter on outlet tee. If installed, this filter must be cleaned annually, or as needed. There is a desire to add a bedroom to the residence. The addition will result in three total bedrooms in the residence. SUBSURFACE To verify sizing of the STA, the subsurface was investigated on January 14, 2021 by digging two soil profile test pit excavations (Test Pits). A visual and tactile soil analysis was completed by Carla Ostberg at the time of excavation.' The materials encountered in the Test Pit #1 consisted of dark brown silt loam to a maximum depth explored of 8.0-feet. No bedrock or groundwater was encountered. The materials encountered in Test Pit #2 were consistent with those encountered in Test Pit #1. The test pits was excavated to a maximum depth explored of 7.0-feet. A sample of the soils was taken from Test Pit #1 at 3-feet below grade. The soil formed a ball and a ribbon less than 1-inch in length before breaking. Soil structure shape was blocky and consistence was firm. Soil structure grade was moderate. Soil texture was more smooth than gritty. STA sizing is based on Soil Type 2, Silt Loam with moderate structure grade. A long-term acceptance rate (LTAR) of 0.6 gallons per square foot will be used. Test Pit #1 Sieved sample ribbon less than 1-inch in length ' Carla Ostberg holds a Certificate of Attendance and Examination from the CPOW Visual and Tactile Evaluation of Soils Training. Table 1 below compares the size of the existing OWTS to sizing requirements for a 3-bedroom residence under current OWTS regulations. 2018 OWTS Regulation Calculations 75 gallons per day (GPD) x 2 persons/bedroom x 3 bedrooms = 450 GPD LTAR = 0.6 gallons / SF (Soil Type 2) 450 GPD / 0.6 gal/SF = 750 SF 750 SF x 1.2 (gravity, bed)2 x 0.7 (chambers) = 630 SF Table 1 Existing 2018 OWTS Regulations Tank Size 1250-gallon, two -compartment septic tank Min. 1000 gallons Soil Treatment Area Gravity, Chamber Bed Infiltrative area: 63 'ARC' ADS chambers in a bed configuration 945 SF Infiltrative area: Min. 630 SF In summary, the system appears to be in working order and sized to accommodate an 3-bedroom residence under current OWTS Regulations. Disclaimer: This inspection is intended only as an evaluation of the present condition of the OWTS based upon what was observed and the Licensed Inspector's expertise in onsite wastewater technology. The Inspector has not been retained to warrant or guarantee the proper functioning of the system for any period of time in the future. Because of numerous factors which may affect the operation of an OWTS, as well as the inability of the Inspector to supervise or monitor the use or maintenance of this OWTS, this report shall not be construed as a warranty by the Inspector that the system will function properly for any particular prospective buyer, and the Inspector disclaims any warranty, either expressed or implied, arising from the inspection of the OWTS or this report. The evaluation does not ascertain the impact the system is having on groundwater. Please call with questions. Sincerely, (i-t. C Ov-s Carla Ostberg, MPH, REHS NAWT Certified Inspector Certification # 11044ITC Exp. April 2022 2 We do not know if the STA was constructed in a trench or a bed configuration.

Don't: • Pour cooking grease or oil down the sink or toilet. • Rinse coffee grounds into the sink. • Pour household chemicals down the sink or flush them. Do: • Eliminate or limit the use of a garbage disposal. • Properly dispose of coffee grounds a food. • Put grease in a container to harden before discarding in the trash. Don't: • Flush non -degradable products or chemicals, such as feminine hygiene products, condoms, dental floss, diapers, cigarette butts, cat litter, paper towels, pharmaceuticals. Do: • Dispose of these items in the trash can! Don't: • Park or drive on your drainfield. The weight can damage the drain lines. • Plant trees or shrubs too close to your drainfield, roots can grow into your system and clog it. Do: • Consult a septic service professional to advise you of the proper distance for planting trees and shrubs, depending on your septic tank location. Don't • Concentrate your water use by using your dishwasher, shower, washing machine, and toilet at the same time. All that extra water can really strain your septic system. Do: • Stagger the use of water -generating appliances. This can be helpful especially if your system has not been pumped in a long time. • Become more water efficient by fixing plumbing leaks and consider installing bathroom and kitchen faucet aerators and water -efficient products.
