Garfield County, Colorado Paul, As requested, SGM, Inc. prepared thisonsite wastewater system (OWS) report for the OWS planned for the subject site. The OWS treatment unit is designated as FilterBoxx Model C-25 2000 GPD WWTP. This treatment system is currently used on well pad sites in Canada and is currently being moved from the F 25 pad site previously permitted. This report presents: typical site (Camp) site characteristics and populations, anticipated wastewater flow and strength characteristics, proposed reuse applications of the treated wastewater, effluent limits, operational and compliance testing procedures, and other applicable guidelines for the, installation and operation of the proposed OWS and disposal of the treated effluent. The OWS shall be operated per the manufacturer guidelines. 1.0 — PROJECT OWNER, SITE DESIGNATION AND LOCATION Site plans for the EnCana Well Pad OWS location are attached. The pad layout plans were prepared by Uintah Engineering and Land Surveying. The site owner, pad designation and location information is presented below: Site Owner: EnCana Associated Pad Site/Camp: Well Pad L24 496 Location: NW IA SW 1/4 Section 24, T4S, R 96W, 6th P.M., Colorado 5716 Burbank Road SE Calgary, Alberta T2H 1Z4 FIIt®rBosr Water and Environmental 2.0 — PROJECT CONTACTS Mr. Nate Denzln, EnCana, Republic Plaza 370 17th St Suite 1700, Denver, CO. 80202 Phone: 720-876-3476 Mr. Glen Volk, FilterBoxx, 7101 5 Street SE, Calgary, BC, Canada, T2H 2G2 Phone: 403-444-8575 Mr. Brian Edwards, FilterBoxx, 131 Buckpoint Road Carbondale Co, 81623. Phone: Cell 970-309-7753. Mr. Bob Pennington, P.E., SGM, Inc., 118 West 6th St, Glenwood Springs, CO 81601. Phone: 970-945-1004. 3.0 — SITE DESCRIPTION AND OPERATION The project site is a working area for a man camp facility and space for the associated support structures and personnel. The site has worker housing with kitchen units, showers and laundry, potable water and sewage storage tanks, and onsite power supply. Site Plans are attached. Based on information from EnCana, the Camp is permitted for a maximum of 24 persons. There will be 24 personnel residing at the camp. Work is performed in two shifts per day. Potable water is currently hauled to the site by Artesian Water Service and stored in above ground tanks for use. Sewage currently generated at the site is stored in tanks and periodically hauled off site for disposal. The FilterBoxx system will recycle the wastewater to an acceptable level for re -use. It is intended to reduce truck traffic, carbon footprint and result in significant cost savings for EnCana. Water fixtures include: toilets, sinks, typical commercial kitchen fixtures, dish- and clothes - washers. It is understood that washing of clothes and bed linen may occur quite frequently at the Camp. 4.0 — PROPOSED OWS It is proposed to install a portable containerized OWS WWTP that has been used at other EnCana sites in Canada. The OWS is a 2000 GPD FilterBoxx system. The OWS consists of a pre -manufactured and modified shipping container utilized to house the treatment compartments and components. The proposed OWS will consist of: a containerized WWTP that will be connected to the final discharge outlet of the camp. The treatment container shall have a settling compartment with 5716 Burbank Road SE Calgary, Alberta T2H 1Z4 FilterBax r - Water and Environmental filtration followed by an aeration compartment with activated sludge and micro -filtration membrane modules. The OWS produces a relatively high-quality effluent with low BODS and TSS, and removal of a significant portion of bacteria including coli forms. Disinfection of the effluent consists of chlorine disinfection prior to final discharge to an above grade holding tank. 5.0 — PROPOSED EFFLUENT REUSE APPLICATIONS It is proposed that the treated effluent will be reused for use 'down hole' in drilling and completion operations, as make-up water, dust mitigation, irrigation or as boiler feed water. We are in the process of expanding approved reuse applications for the industry. This will be in accordance with CDPHE Regulation 84 standards for reclaimed water and a letter of intent will follow. The reuse water should be reused in accordance with COGCC direction and approval for these purposes, and pursuant to Article IX, Section C of the Garfield County ISDS regulations. We have provided a copy of the COGCC sundry notice filed for your records 6.0 — EFFLUENT LIMITS The following Effluent Limits have been applied by Garfield County to this OWS: • The geometric mean of the fecal coli form density shall not exceed 25 per 100 milliliters when averaged over 5 consecutive samples, and no single result for fecal colt form shall exceed 200 per 100 milliliters. • The arithmetic mean of the standard 5 -day biochemical demand (BODS) shall not exceed 20 milligrams per liter when averaged over 3 consecutive samples. • The arithmetic mean of the total suspended solids (TSS) shall not exceed 40 milligrams per liter when averaged over 3 consecutive samples. 6.1 Effluent Compliance Testing: Garfield County will require at least three (3) consecutive tests for the items listed about to be in compliance at the startup of the OWS at the proposed location, and prior to reuse of the treated effluent. Monthly sampling will be allowed there after with no more than 30 days between these samplings provided that additional sampling/testing is completed as outlined in 6.2 below.. All sampling should follow standard procedures for wastewater sampling, sample protection and delivery to an approved laboratory. The discharge hose shall be flushed with at least 10 gallons of effluent prior to taking these samples. 6.2 Other Testing: The owner and/or operator of the OWS perform routine residual chlorine testing and turbidity of the effluent. The discharge hose shall be flushed with at least 10 gallons 5716 Burbank Road SE Calgary,Alberta T2H 1Z4 1 rltereoaar Wafer and Environmental of effluent prior to taking these samples. Portable test kits approved for use by the EPA for use in the water and wastewater treatment industries shall be used. All testing shall be performed per the testing guidelines for the testing equipment. Testing equipment shall be calibrated as necessary. Daily routine testing shall be recorded on a 'bench sheet' kept at the OWS. All effluent flushed from the discharge hose shall be retumed to an appropriate lift station for reentry to the OWS. 7.0 — ANTICIPATED SEWAGE CHARACTERISTICS 7.1 Proposed Maximum Daily sewage Flows: It is proposed that the OWS be handle an average of 1,999 GPD with a peak daily loading factor of 150% for a peak daily flow of 2,999 GPD. Flow meters are installed and data logged to record flows on the discharge line. 7.2 Anticipated Peak Hourly Flow Rates: Flow information for peak hourly flow rates is not available. Peak hourly flow rates are anticipated to be up to 40% of the total daily flow (1200 gallons) and occurring over a two hour period coinciding with the change in work shifts. The peak flows are anticipated to occur once or twice a day. This results in a potential peak flow of 600 gallons per hour (gph), or 10 gpm on average. This results in an hourly peaking factor of 7.2 which is typical for small communities and commercial establishments which typically range between 4 to 10. 7.3 Anticipated Peak Month and Week Flows: Peak daily flows during the peak month and week are anticipated to be equal to the proposed average daily and peak daily flow rates of 1,999 gpd and 2,999 gpd, respectively. Table k Summary of Proposed Hydraulic Flow Rates Design Parameter Quantity Comment Average Daily Flow Rate 1,999 gpd Maximum allowed by County Maximum Daily Peak 2,999 gpd Maximum allowed by County Maximum Hourly Flow Rate 600 gph over a 2 -hour period Hourly Peaking Factor of 7.2 If the actual sewage flows rates will be higher than that presented herein, SGM and FilterBoxx should be notified to re-evaluate the suitability of this OWS design, if necessary. 5716 Bu rbank Road SE Calgary, Alberta T2H 1Z4 Fil#erinir Water and Environmental 7.4 Anticipated Organic and Solids Loading: It is anticipate the actual strength of the raw sewage may be strong. For this OWS design, the anticipated strength of the raw influent is considered to be high strength sewage with BODs concentration of +/-1,000 mg/I, and a TSS concentration of +/- 500 mg/1. Table B: Summary of Anticipated Or anic and Solids Loading BOD5 1,000 mg/I TSS 500 mg/l Confirmation BOD5 and TSS loading is recommended for several of the EnCana sites prior to OWS purchase and installation. 7.5 Anticipated Nutrient Loading: Testing for Total Nitrogen and Phosphorous were not performed on the existing sewage. For this OWS design, Total Nitrogen (TN) concentrations may be on the order of 75 to 100 mg/I and Total Phosphorous (TP) concentrations on the order of 8 mg/I are anticipated. Nitrogen and/or phosphorous reduction are not apart of this OWS design. 7.6 Anticipated Influent Temperature, Ph and Alkalinity: It is assumed that the temperature of the influent raw sewage will be on the order of 60 to 70 degrees F (15 to 20 degrees C). Influent pH and alkalinity are assumed to be adequate in the raw influent to support the activated sludge, or will be adjusted by the OWS operator as necessary. 7.7 Anticipated Fats, Oils and Greases (FOG): It is anticipated that fats, oils and greases will be a component of the wastewater stream. Adequately sized interceptors must be installed in the Camp kitchen(s) to achieve at least 95% removal of all FOG before entering the OWS. Fog removal Is a pretreatment requirement for the proposed OWS per FilterBoxx. 7.8 Toxic Chemicals: It is understood that some toxic chemicals in the form of typical cleaning chemicals may be in use at the Camp. These may include: bleach, chlorine based cleaning agents, and other disinfectants. This OWS design and specifications assume that no toxic materials will be introduced Into the OWS, or, at a minimum, any toxic agents will be in low concentrations as to not affect OWS performance. The owner shall provide a list of cleaning agents and chemicals used at the Camp with the potential of being introduced to the OWS. It may be necessary to change the chemicals being used at the Camps to minimize any potential detrimental effects to the OWS. Toxic chemicals, if introduced into the OWS, may render the OWS ineffective. 5716 Burbank Road SE Calgary, Alberta T2H 1Z4 FI►tereos r� Waterand Envlmnmm�tM 8.0 — PRETREATMENT REQUIREMENTS The membranes are very sensitive to fouling from fats, oils and greases (FOG). The Camp has an on-site kitchen(s) similar to a small scale commercial kitchen. Every attempt must be made by camp personnel to minimize the (FOG) entering the system. A grease interceptor installed below grade is an altemative to interior fixtures. EnCana will be responsible for providing the required tank or facilities to handle FOG removal prior to entering the OWS. 9.0 — SEWAGE COLLECTION SYSTEM Sewage will be collected by an existing onsite sewer system via lift stations. Piping from the trailers will use 4 inch ABS and will transition to 4 inch Femco flexible coupling upon entering the lift stations. Each lift station will include a 110 volt single % Hp solids handling pump for discharge to the FilterBoxx collection: tank. The lift stations will be connected together with 2 inch heat traced hoses which are shrouded.: The lift stations will be daisy chained together for discharge to the inlet manifold of the Filterboxx treatment unit. This will eliminate the need for a portable septic tank at each trailer and eliminate truck traffic on the well pad resulting in savings and improving safety issues. 9.1 Sewage Pumping System: Ata minimum, the effluent pumping system should meet the following specifications: 9.1. A— Pump: The effluent pump for the effluent dosing shall be at least'/ HP, and be UL and CSA listed as an effluent pump. Pump is to be activated by a motor -contact switch in the control panel and from the float switches or pressure sensors in the basin. 9.1. B — Access Risers: Access risers that extend to final grade must be provided. The risers are to be watertight and attached to the septic tanks such that a watertight seal is provided. Risers should be rated for the appropriate load requirements. 9.1. C — Discharge Assembly: The pump discharge assembly should have a disconnect union accessible from the ground surface to allow pump replacement. The discharge assembly is to be plumbed with a weep hole to allow drainage between cycles to minimize freezing potential, or otherwise protected from freezing per typical site methods. 5716 Burbank Road SE Calgary, AlbertaT2H 1Z4 FiIterBosr water and rxnAmnmeniat 9.1. D — Electrical Splice Boxes: The splice boxes shall be UL approved for wet locations (NEMA 4X). All wire splices are to be completed with UL listed waterproof splice connectors, 9.1. E — Controls and Alarms: Controls and alarms shall be listed per UL 508. Controls are to include a toggle switch for manual operation of the pump; separate dedicated circuits for the pumps and water level monitoring devices; an audible and visual alarm. Exterior panels or panels placed in wet areas shall be NEMA 4X rated. 9.1. F — Location: The pump control panel is to be mounted within sight of the respective pump system. The panels are also to be located such that the alarm can be readily seen and heard (remote alarms to a location within the buildings can be provided). The panels are to be mounted at convenient heights to allow access and maintenance. 9.1. G — Processed Water Tank: Under the current configuration the treated water is to be discharged to an insulated, above ground 4200 gallon storage tank for reuse. This allows for the moving of water around the pad based on acceptable and approved uses. Encana is responsible for the pump and piping to the approved use tank 9.2 Hose and Pipe Connections: EnCana shall provide appropriate connection devices to allow for the pump hoses and/or pipes to connect with the OWS. The connection at the OWS shall have a 'quick -connect' such as a cam and grove connection, or other suitable device. All above grade hoses shall be protected from freezing. All piping both potable and non potable is to be clearly identified to prevent mishaps. Below grade pipes can be sloped to drain between pump cycles or insulated to protect from freezing. 10.0 — AERATION Since the FilterBoxx units are proprietary units, FilterBoxx has engineered the size of the aeration system based on the aeration capacity of each unit, site elevation, desired operating and maximum MLSS concentrations and oxygen transfer rates, anticipated influent BODS concentration (750 mg/I), and the information presented in the Table D below, and the capabilities of the FilterBoxx units. Table D: Aeration System Sizing Parameters Item Design Site Elevation +/- 6000 feet MSL Outside Air Temperature -40 to 120 F OWS Operating Temperature 8 C to 25 C Salinity Factor 0.95 (assumed) 5716 Burbank Road SE Calgary, Alberta T2H 1Z4 FilterBeiarmenfaf- Waterind EnWmn 11.0 — DISINFECTION Chlorine disinfection with a Sodium Hypochlorite (NaOCI) solution (bleach) is recommended due to the residual disinfection effects of the chlorine. The solution typically comes in 5.25%, 10% or 15% concentrations. The concentration of the chlorine solution in the final discharge tank should result in a residual free chlorine concentration of a positive reading above 0 to provide for pathogen kill upon leaving the system. The dosage shall be determined in the field with bench testing by the OWS operator for actual chlorine demand. The lower residual chlorine concentration provided the fecal coli form test results indicate adequate disinfection at the lower levels. Point of compliance testing shall take place upon final discharge of the effluent measured inside of the plant at the hose bib on the discharge line from the plant. The FilterBoxx unit has a sampling port on the final discharge line. It will also contain both an in line TSS meter and chlorine analyzer. Data from both units can be downloaded and stored for preparation of reports. It is recommended that testing could also take place in the storage tank after treatment. All water from the final treatment tank is to be transported by an approved hauler. A log is to be kept on site for review detailing the destination, use and volume transported. 12.0 — FLOW MONITORING The influent flow rate shall be monitored ensuring that permit conditions are met so as not to exceed the allowed limit of 1999 GPD. The meters will provide both instantaneous flow rates and totalized flow volumes upon entering and: leaving the treatment system to ensure permit conditions are met. 13.0 — OWS MONITORING AND CONTROLS The OWS shall have a control panel accessible to the owner. All electrical motors shall be controllable from the panel. The control panel shall be connected to a PC located in a nearby trailer for monitoring the OWS. The OWS motor controls and alarms shall be tested prior to placing the OWS into service. The PC shall have alarm notification for the owner/ company man on site who will contact the service representative service as required. Wherever possible every attempt will be made to provide for remote telemetry. The current system is able to receive a Verizon signal and we are piloting a system on an experimental basis. 14.0 — ELECTRICAL POWER SUPPLY AND CONNECTIONS It is understood that the on-site power supply is from generators and that the power is 208 VAC and 3 Phase. The main electrical connection to the OWS shall be on the exterior of the OWS, and labeled. The connection shall meet applicable OSHA and NEC guidelines, and owner requirements. All electrical systems shall be grounded as required. 5716 Burbank Road SE Calgary, Alberta T2H 1Z4 FinerBu r- Waierand Environmental 15.0 — SITE PREPARATION The location of the OWS shall be graded smooth and be stable under construction traffic with no deflection of the sub grade soils. Proof -rolling with a fully -loaded dump truck or water truck is recommended. Any sub grade soils that deflect under loading shall be removed or otherwise stabilized. All fill soils below the OWS shall be compacted to at least 95% of the standard Proctor maximum dry density (ASTM D 698). 16.0 — OPERATIONS AND MAINTENANCE The goal of an operation and maintenance schedule is to observe the operation, and perform minor maintenance to the onsite wastewater system to allow for proper, long term functioning of the system. An operation and maintenance schedule or contract with a private maintenance company is recommended. 16.1 Settling Compartments: Should FnCana decide to provide a settling tank, the scum and sludge accumulation in the septic tank should be monitored yearly. Once the scum or sludge thickness reaches 25% of the liquid depth, the entire tank should be pumped. 16.2 Effluent Filters: Effluent filters: should be cleaned (hosed off) at the time of pumping or as needed. 16.3 General: System users must realize an onsite wastewater system is different from a public sewer service. Plastic or other non -biodegradable material should not be introduced into the system. Biodegradable cleaners should be used. Water use should be monitored. A malfunctioning toilet can consume a large amount of water. This excess water in addition to daily loading could flood and irreparably harm the OWS. Allowing fixtures to flow continuously to prevent water lines from freezing is not recommended. Although the proposed system can accommodate variable flows, spreading water use over the day and minimizing peak flows is recommended. The design of the OWS is based on the treatment of domestic sewage only. No industrial or hazardous wastes should be introduced Into the OWS. 5716 Burbank Road SE Calgary, Alberta T2H 1Z4 ut Water and Envbnnmental 16.4 Equipment Repair: The repair and/or replacement of equipment shall be recorded on the 'bench sheet' at the OWS. 16.5 Backup Equipment: The OWS owner and/or operator shall have backup mechanical and electrical equipment, as necessary, to repair the OWS. Spare parts shall be available for the OWS within a short period of time as to not significantly impact OWS operations. 17.0 — LIMITATIONS The OWS diagrams, specifications and recommendations presented herein are based on data submitted, the planned use of the OWS, and with recent experience with this unit at other drill pad locations. If the proposed sewage characteristics and flow rates, the intended OWS use, and the effluent reuse plans, are different than that described herein, SGM and FilterBoxx should be notified to evaluate the effect of the changes on the wastewater system. The installation of the OWS shall be per applicable county building/environmental codes, and per manufacturer guidelines. ons,please G E�0 jgT` Q STTB ' <cs ° PL IN PIR PIC / n e Briaia� 0 OWas1 i0i/P Projectg�'�®o`° �mrnnneP Robert Pennington P.E.
