Phil Vaughan 1038 County Road 323 Rifle, CO 81650 Onsite Wastewater Treatment System Design – Vault and Haul WPX Energy – Trail Ridge Employee Housing Facility Garfield County, Colorado Phil, ALL SERVICE septic, LLC has completed an onsite wastewater treatment system (OWTS) vault design for the subject employee housing facility. This design is in accordance with Section 7-705 of the Garfield County Land Use and Development Code and Garfield County On-Site Wastewater Treatment System Regulations, Section 43.12 D. The Site is located in a rural area of Garfield County where OW TSs are necessary. The legal description of the property is as follows: Section 3, Township 5 South, Range 97 West of the 6th Principal Meridian, County of Garfield, State of Colorado. SITE CONDITIONS The above mentioned property (Site) is accessed via Rio Blanco County Road 5 and BLM Road No. 1009. A previously excavated flat pad exists on the Site and a 60’ x 125’ Storage Building will be developed on this portion of the Site. The employee housing will consist of six factory-built units with a footprint of approximately 72’ x 58’ and will be located east of the excavated pad. The proposed septic tanks (vaults) will be located south of the employee housing units. This area slopes to the south and is currently vegetated with sage and native grasses. Potable water will be hauled to the Site. The 10,000-gallon potable water skid will be located at least 25- feet from the proposed septic tanks. Page 2 DESIGN SPECIFICATIONS A 24-person employee housing facility is proposed. The OWTS vault design is based on a wastewater flow (Q) of 1999 gallons/day. OWTS Calculations: 75 gallons/person x 24 people = 1800 gallons/day Using 1999 gallons/day Vault capacity = 1999 gallons x 48 hours = 3398 gallons minimum Using 1500 gallon + 1500 gallons + 1500 gallons = 4500 gallons A commercial kitchen will be part of the employee housing facility. A grease recycling procedure will be implemented to minimize grease entering the OWTS. Grease will be collected in a bucket stored in the kitchen. The grease will then be transferred to a bear-proof recycling container located at the exterior of the kitchen. The sewer line exiting Unit MDP is 2 ½-inches in diameter and 10 ½-inches above the ground surface. The sewer line exiting Unit LP4 is 3 ½-inches in diameter and 8-inches above the ground surface. Both sewer pipes will transition to a 4-inch diameter, schedule 40 sewer line with double-sweep clean outs. Heat trace and insulation must be installed on all above grade sewer lines. The OWTS installation will include two 1500-gallon, single compartment septic tanks, followed by one 1500-gallon, two-compartment septic tank. An alarm float must be set at 17-inches above the bottom of the tank in the first compartment of the third 1500-gallon, two-compartment tank. The high water alarm will connect to “Smart Camp” security system. An Orenco® AMAHW alarm and panel is recommended. Specifications are enclosed. Other alarms and control panels or ultra-sonic options may be considered. Once the alarm signals, pumping must be coordinated, understanding the septic tanks are at 75% capacity, with 1125 gallons of capacity remaining. Septic tanks must have PVC risers on all manhole access ports brought to grade. Tee posts and fencing (or steel bollards) must be placed around the tanks to eliminate the possibility of traffic over the area of the septic tanks. The component manufacturers are typical of applications used by contractors and engineers in this area. Alternatives may be considered or recommended by contacting our office. Construction must be according to Garfield County On-Site Wastewater Treatment System Regulations, the OWTS Permit provided by Garfield County Building Department, and this design. OPERATION INFORMATION AND MAINTENANCE The following items must be provided in accordance with Section 7-705 of the Garfield County Land Use and Development Code: a) Year-round access must be available and maintained for safe and regular access for sewage hauling vehicles; b) WPX Energy must demonstrate and guarantee an arrangement for hauling sewage; c) WPX Energy must maintain all records, including but not limited to, trip logs, reports, and landfill receipts; and d) Sewage disposal records must be maintained as public records and be available to the County upon request. Page 3 Garbage disposal use should be minimized, and non-biodegradable materials should not be placed into the OWTS. Grease should not be placed in 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. 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. ALL SERVICE septic, LLC should be notified 48 hours in advance to observe the installation. LIMITS: The design is based on information submitted. All OW TS construction must be according to the county regulations. Requirements not specified in this report must follow applicable county regulations. The contractor should have documented and demonstrated knowledge of the requirements and regulations of the county in which they are working. Licensing of Systems Contractors may be required by county regulation. Please call with questions.

They can also be used as a remote alarm when provided with a 120 VAC signal from a primary control panel. General AMAHW and AMLAHW alarm panels feature a 7⁄8-in. (22-mm) red alarm light and an audible alarm. The AMAHW alarm resets automati- cally; the AMLAHW alarm resets manually. For stand-alone use, both panels can be used with either a mechani- cal or a mercury float switch that is rated for 120 VAC power. AMAHW and AMLAHW alarm panels are listed per UL-508 and cUL-508; a CE listing is available.
