Nelly Construction installed the system and photo -documented the installation. The installation included a new 1000 -gallon, two-compartment concrete septic tank with an effluent filter on the outlet tee. This filter must be cleaned annually, or as needed. The septic tank was installed just outside of the driveway. The existing septic tank, located partially under the stairs, was filled with rock and abandoned in- place, along with the existing absorption area. Effluent gravity flows from the septic tank to a distribution box, accessible from grade, just below the landscape wall. The distribution box was filled with water and flow regulators were installed to assure equal distribution. Effluent gravity flows from the distribution box to five gravelless chamber beds. Four beds have 2 rows of 9 `Quick 4 Infiltrator® chambers and the fifth bed has 3 rows of 6 `Quick 4' chambers for a total of 90 chambers and 888 square feet of infiltrative area. The OWTS was generally installed according to specifications. This observation is not a guarantee of workmanship and/or parts and materials. ALL SERVICE septic, LLC should be notified if changes are made to the OWTS in the future. Any additional OWTS construction must be according to the county regulations. LIMITS: Observations are limited to components that are visible at the time of the inspection. The installer must have documented and demonstrated knowledge of the requirements and regulations of the county in which they are working. The quality of the installation is dependent of the expertise of the installer, soil type, and weather conditions. Please call with questions.

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. Don't: • Flush non -degradable products or chemicals, such as feminine hygiene products, condoms, dental floss, diapers, cigarette butts, cat litter, paper towels, pharmaceuticals. Don't: • Park or drive on your dra infield. 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: • Eliminate or limit the use of a garbage disposal. • Properly dispose of coffee grounds & food. • Put grease in a container to harden before discarding in the trash. Cho: • Dispose of these items in the trash can! Do: • Consult a septic service professional to advise you of the proper distance for planting trees and shrubs, depending on your septic tank location. • 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. • 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 efficien by fixing plumbing leaks and consider installing bathroom and kitchen faucet aerators and water -efficient products.

The property is located outside of Redstone, in an area where OWTSs and wells are necessary. The legal description of the property is Lot 44 and 45 and Lot 52 thru 54, Elk Mountain Subdivision. SITE CONDITIONS A 2 -bedroom, single-family residence presently exists and is utilizing an existing OWTS. There is a desire to upgrade the existing OWTS. There is a private well located on the property. A minimum setback of 100 -feet must be maintained from the well to the absorption area and 50 -feet from the well to the septic tank. SUBSURFACE The subsurface was investigated on June 2, 2014 by digging one 8 -foot profile pit and running percolation test. Percolation tests were run in three holes, with results recorded in Table 1, Percolation Test and Soil Data Form, enclosed. Percolation rates ranged from 13 to 40 MPI, with the average percolation rate at 24 minutes per inch (MPI). The materials encountered in the profile pit consisted of light brown, slightly moist, granular, gravelly sand to a depth of 3 -feet, underlain by medium brown, 'moist, granular, gravelly sand with some large, angular cobbles to a maximum depth explored of 8.0 -feet. No bedrock or groundwater was encountered. The profile pit was excavated at high runoff. A percolation rate of 25 MPI will be used in this design. Page 4 OPERATION INFORMATION AND MAINTENANCE The property owner shall be responsible for the operation and maintenance of each OWTS servicing the property. The property owner is responsible for maintaining service contracts for manufactured units, alternating absorption systems, and any other components needing maintenance. Geo -fabrics or plastics should not be used over the absorption area. No heavy equipment, machinery, or materials should be placed on backfilled absorption area. Livestock should not graze on the absorption area. Plumbing fixtures should be checked to ensure that -no additional water is being discharged to OWTS. For example, a running toilet or leaky faucet can discharge hundreds of gallons of water a day and harm an absorption area. The homeowner should pump the septic tank every two years, or as needed gauged by measurement of solids in the tank. Garbage disposal use should be minimized, and non -biodegradable materials should not be placed into the OWTS. Grease should not be placed in household drains. Loading from a water softener should not be discharged into the OWTS. No hazardous wastes should be directed into the OWTS. Mechanical room drains should not discharge into the OWTS. The OWTS is engineered for domestic waste only. ADDITIONAL CONSTRUCTION NOTES If design includes a pump, air release valves and weep holes should be installed to allow pump lines to drain to minimize risk of freezing. Excavation equipment must not drive in excavation of the absorption area due to the potential to compact soil. Extensions should be placed on all septic tank components to allow access to them from existing grade. Backfill over absorption area must be uniform and granular with no material greater than minus 3 -inch. INSTALLATION OBSERVATIONS ALL SERVICE septic, LLC must view the OWTS during construction. The OWTS observation should be performed before backfill, after placement of OWTS components. Septic tanks, distribution devices, pumps, dosing siphons, and other plumbing, as applicable, must also be observed. ALL SERVICE septic, LLC should be notified 48 hours in advance to observe the installation. LIMITS: The design is based on information submitted. If soil conditions encountered are different from conditions described in report, ALL SERVICE septic, LLC should be notified. All OWTS construction must be according to the county regulations. Requirements not specified in this report must follow applicable county regulations. The installer should have documented and demonstrated knowledge of the requirements and regulations of the county in which they are working. 0 Please call with questions.
