No person shall install, renovate, or repair an OWTS in Eagle County (EC) without a valid EC Systems Contractor License. Any person that conducts a business as a systems contractor without having obtained a valid license section commits a Class 1 petty offense as defined in section 18-1.3-503, C.R.S. Please notify the department when an installer is identified, prior to installation of the OWTS. Alteration to existing OWTS, permit 2369-04IS, exactly as depicted in the LKP Engineering, Inc design stamped, signed, and dated January 21, 2021 by Luiza Petrovska, PE. The alteration of the system is designed to accommodate the increased maximum daily flow from the addition of two bedrooms to the existing five bedroom residence, for a total of seven bedrooms. The soil treatment area was determined by the PE as adequately sized to serve seven bedrooms, based on analysis of previous soils test and current regulations, and so will remain as existing. The alteration consists of the addition of a new 1000 gallon Valley Precast single compartment concrete tank, prior to (or upstream to) the existing tank 1500 gallon septic tank, determined to be in working order, and will remain as existing. The 1500 gallon tank must be pumped and a new effluent filter installed on the outlet tee. Note: Do not install the new tank in wet or frozen ground. Contact Eagle County Environmental Health and the design engineer well in advance of requesting inspections prior to backfilling any component of the OWTS. The design engineer is responsible for conducting all inspections necessary to certify the installation and assure the functionality of the system. System certification, along with photos and a record drawing is required to be submitted to and approved by Eagle County Environmental Health prior to the use of the system.

Box 3388 Eagle CO 81631 brennen@sstaia.com RE: Engineering Services for the McCormick Residence Addition - OWTS for 7 bedrooms Lot 5, Block 1, Cordillera Filing 36 0254 Pine Marten Way Eagle County, Colorado Project No. 03069 Old ISDS Permit Number 2369-04 Dear Brennen: The following report is a summary of our evaluation, of the existing Onsite Wastewater Treatment System and the required improvements for the proposed two-bedroom McCormick Residence Addition on Lot 5, Block 1, Cordillera Filing 36, 0254 Pine Marten Way, Eagle County, Colorado. The calculations and the layout of the required improvements are shown on the attached drawing C-1. The existing system, ISDS Permit Number 2369-04, was designed for a 5-bedroom residence and it was constructed on October 18, 2004. The system consists of a 1500-gallons, two compartments concrete septic tank and a Soil Treatment Area with 60, Standard Infiltrator Chambers constricted in four trenches with 16 chambers in each of the first two trenches and 14 chambers in each of the last two trenches. The proposed addition will add two more bedrooms to the existing five for a total of 7 bedrooms. An additional, 1000-gallons, one compartment concrete septic tank will be added just before the existing, 1500-gallon, two compartment concrete septic tank, as shown on the attached drawing. An effluent filter (per the OWTS #43 regulations) will be installed on the outlet tee of the second (existing) tank. The existing Soil Treatment Area (STA) was re-calculated based on the present OWTS #43 regulations for the total number of 7 bedrooms (existing and proposed). Per the new regulations the Maximum Daily Flow was calculated for the allowed 2 persons per bedroom for the first three bedrooms plus one additional person for each additional bedroom for a total of 10 people. The maximum daily flow was calculated to be 750 gpd. With the LTAR = 0.5 gpd/sf, based on the Percolation Rate of 32 minutes per inch, done on June 4, 2003, the required STA was calculated to be 1500sf. With the allowed 30% reduction for Infiltrator Chambers the size of the required area is 1050 sf. Based on the allowed 12sf for the surface of Quick 4 Plus Infiltrator Chambers, the required number of infiltrators will be 88 with 88 infiltrators x 4 feet = 352 lineal feet. The existing STA has 60 chambers at 6.25 feet = 375 lineal feet. The existing STA has greater capacity than the required 352lf, thus no additional McCormick Residence Addition - OWTS Page 2 of 2 January 21, 2021 Project 03069 P.O. Box 724, Eagle, CO 81631 Tel (970) 390-0307 www.LKPEngineering.com trenches with infiltrator chambers will be required. You or your licensed installer will apply for a repair permit, for the installation, connection and backfilling of the new tank, and will make sure that all the required setbacks are met. Once the new septic tank is installed with all the connections completed, you or your installer will give a 48-hour notice to LKP Engineering and the ECEH Department to schedule the inspection. DO NOT backfill any part of the system prior to the inspection. If you have any questions, please do not hesitate to call. Sincerely, LKP ENGINEERING, INC.

Box 1534 Eagle, CO 81631 altitudeseptic@gmail.com www.altitudeseptic.com 1/15/2021 254 Pine Marten Way Edwards, CO 81632 To Whom It May Concern, As requested, Altitude Septic performed a septic system inspection at the above address on January 11, 2021. The 2.968-acre lot is located southwest of Edwards in an area that requires utilizing an OWTS and is listed under parcel number #210716102005. The system was installed under permit #2369-04 which called for a 1,500-gallon, concrete, tank with 60 infiltrator chambers in four trenches, and was finalized in November of 2004. The original design was sized to accommodate a five-bedroom residence. The septic tank is on the west side of the structure with both lids accessible at the surface. A clean-out was visible between the house and the tank. There are two risers on the inlet side and one on the outlet with both baffle tees in place as required. The liquid level in the tank was normal and the concrete is in good condition. Sludge levels were measured during the inspection and were about 40% of the septic tank capacity. We would recommend pumping the tank out and installing an effluent filter on the outlet side of the tank to help prolong the life of the STA (Soil Treatment Area). The STA is northeast of the septic tank in a trench configuration utilizing serial distribution. With snow cover present we were unable to locate the inspection ports for the trenches, but the area was walked and observed with no visible indications of surfacing or failure. We were informed that the residence had been occupied from June through December of last year, so if a failure existed it would have been visible because of the occupancy and use of the drains. As mentioned above, the septic tank was at normal level as well. After the inspection we would make the following recommendations: • Pump the septic tank. Every 3-5 years is recommended for full time occupants. • Install an effluent filter on the outlet side of the tank. The filter should be checked every 2-3 years and cleaned as needed. Please contact me directly with any additional questions at (970) 471-6292.
