The facility is geographically located in the northeast Y of the northwest ' of Section 25, Township 5 North, Range 65 West of the 6th Principle Meridian, Weld County, Colorado. Construction of the facility is schedule to begin in April 2009. Spill containment and other additional controls are expected to be required as part of the USR approval. Weld County has indicated that one of the requirements of the USR will be development of a groundwater monitoring program at the facility to assess the shallow unconfined aquifer for potential releases from the facility. The first phase of the groundwater monitoring program is the development of this Groundwater Monitoring Plan, which will be provided for public review and comment. Following discussion and resolution of comments with Weld County, the Groundwater Monitoring Plan will be finalized and implemented. 2.0 FACILITY DESCRIPTION The general facility layout is shown on Figure 2 in Appendix A. The High Plains Disposal Weld Site #1 receives, stores, and processes Class II waste water from oil and gas exploration and production (E&P). Recovered oil and condensates are stored and shipped to other facilities for further processing. After oil-water separation, processed water (brine) is re-injected into the facility's Class II injection well. Groundwater Monitoring Plan High Plains Disposal Weld Site#1 Kersey, Colorado Terracon Project No. 20097021 April 2009 2.1 Process Description E&P waste water will arrive at the facility in tanker trucks, each of which will check in at the office prior to unloading. The tanker truck will pull into the unloading containment area and park to prepare for inspection and unloading. The facility attendant will visually inspect a sample of the tanker's load to assess if the load is acceptable as a Class II Waste (per COGCC regulation) prior to allowing the tanker to unload into the waste processing and disposal system. If a load is not acceptable to enter the system it will be rejected and unloading will not be allowed. Upon approval by the facility attendant, the tanker truck will unload by gravity feed into the receiving pit which will be a 9 feet deep by 61 feet long by 20 feet wide coated-concrete structure. A skimmer will remove oils from the fluids in the pit and receovered oils will be pumped to one of two 750-barrel (BBL) oil/condensate tanks. The waste water is then pumped to one of two 600 BBL "gun barrel" separators, where the aqueous and hydrocarbon phases are separated. The processed waste water is then gravity-fed to six 750 BBL water holding tanks, and the hydrocarbon liquids are gravity-fed to one of the two 750 BBL oil/condensate tanks. The processed waste water is filtered and disposed by underground injection into the facility's Class II underground injection well, which has been permitted in accordance with COGCC regulations. The transfer piping will be underground. Recovered oil and condensate will be sold to a third party. Tanker truck loading of oil and condensate will occur in the loading containment area. Tanker trucks will park inside the loading containment area and connect directly to one of the condensate tanks for loading. Pre-injection filtration wastes will be periodically removed as needed. Solids and sludges that accumulate in the receiving pit and water tanks will be cleaned out on an as-needed basis, currently expected to be semiannually or annually. When clean-out occurs, the pit or tank to be cleaned will be pumped down to allow for a third-party contract to enter and manually clean out accumulated solids and sludges with a vacuum truck. Sludges and filtration wastes will not be not dried or disposed of on- site. These waste materials will be removed on an as-needed basis and taken off- site for disposal. According to COGCC records, the facility's injection well is permitted as COGCC well "HPD Kersey 1" and was permitted for proposed injection into the Lyons Formation 2 Groundwater Monitoring Plan High Plains Disposal Weld Site#1 Kersey, Colorado Terracon Project No. 20097021 April 2009 approximately 10,500 feet below ground surface (bgs). COGCC records have not been updated to reflect the 2009 completion and integrity testing of the well. A designated High Plains operator will be on site during operation of the processing facility including offloading, liquid transfers, loading, and injection. The facility expects to a daily throughput of up to 10,000 BBL of waste water per day. The facility anticipates operating 365 days a year. 2.2 Tank and Processing Inventory The table below provides a summary of the process areas and tanks. No. of Size Content/Process Tanks (BBL) Processing and Storage — Hydrocarbon/water separation, storage 2 600 Gunbarrel Separators — Hydrocarbon/water separation 2 750 Recovered Oil and Condensate storage 6 750 Processed Water (brine) storage Receiving Area — Concrete pad and steel-covered open trench/pit • Tanker truck unloading (gravity feed) of influent E&P waste water • Skimmer recovers oils which are pumped to oil/condensate storage tanks • Settled solids manually cleaned out by vacuum truck on as-needed basis • Tanker truck loading (pumped) of oil and condensate from storage tanks Pump House — Pump and Process Controls, Filtration of Processed Water Injection Well, Underground Transfer Piping 2.3 Secondary Containment The processing and storage tank battery will be installed within a containment system consisting of a coated-concrete floor and perimeter concrete dike designed to hold 150% of the largest tank in the area. The receiving area will be under canopy and 3 Groundwater Monitoring Plan High Plains Disposal Weld Site #1 Kersey, Colorado Terracon Project No. 20097021 April 2009 will be contained using concrete sloped inward toward the steel-and concrete unloading pit. A Spill Prevention Control and Countermeasures (SPCC) Plan is currently being prepared to help manage potential spills and releases from the facility. The SPCC Plan will include regular facility inspection procedures to aid in discovery, assessment, and cleanup of a spill, if one occurs. In addition, the SPCC Plan will include preventative measures to help reduce the potential of spill occurring. 3.0 GROUNDWATER MONITORING WELL INSTALLATION Proposed locations for installing groundwater monitoring wells at the site are shown on Figure 3 in Appendix A. Well locations are proposed based on the estimated regional topographic conditions and major surface water locations, which suggest a shallow hydrogeological gradient is to the north-northwest at the facility. A total of three wells have been selected in the presumed downgradient direction of major facility operations and storage. No wells are currently proposed upgradient (i.e., representing "background" or incoming conditions) of major facility operations or storage. In the event that groundwater flow varies significantly from the direction presumed based on topography, or if there is a need to evaluate upgradient conditions, additional wells may need to be installed. 3.1 Preparation for Drilling At least 72 hours prior to drilling, Terracon will contact the local utility marking service to clear proposed drilling locations. Also at least 72 hours prior to drilling, Terracon will submit groundwater monitoring well permit applications to the Colorado Division of Water Resources (DWR). 3.2 Drilling and Well Installation Monitoring well installation will be performed in general accordance with applicable rules and regulations described in DWR's well installation rules and regulations section of the Code of Colorado Regulations (CCR), 2 CCR 402-2. For each well, Terracon will use a hollow-stem auger to advance a soil boring to the shallow groundwater table or a maximum depth of 30 feet bgs. Soil samples will be collected from the boring using a split spoon sampler at approximate five-foot intervals to the top of the saturated zone. Lithology of subsurface soils observed during drilling will 4 Groundwater Monitoring Plan High Plains Disposal Weld Site#1 Kersey, Colorado Terracon Project No. 20097021 April 2009 be logged in the field. Soil samples will be screened in the field for evidence of contamination by visual and olfactory examination and by measurement of volatile headspace using a photoionization device (PID). Each soil boring will be completed as a permanent 2-inch groundwater monitoring well as follows: • Installation of 10 or more feet of 2-inch diameter 0.010-inch machine slotted PVC well screen with a threaded bottom cap; • Installation of 2-inch diameter threaded, flush-joint PVC riser pipe to approximately 3 to 4 feet above the surface; • Addition of pre-sieved 20/40 grade silica sand for annular sand pack around the well screen from the bottom of the boring to approximately 2 feet above the top of the well screen; • Placement of 2 feet of hydrated bentonite pellets above the sand pack; • Addition of cement/bentonite slurry to the surface; and, • Installation of metal stick-up casing. Locking caps will be installed on each well. A typical groundwater monitoring well completion diagram is included as Figure 4 in Appendix A. Terracon personnel will return 2 to 3 days after installation to develop the wells using a surge block device and disposable bailing device. Wells will be developed by removing approximately five well volumes of groundwater. Well elevations will be measured relative to an arbitrary datum using a rod and level. Drilling equipment used will be cleaned using a high-pressure washer prior to beginning the project and before beginning each boring. Non-dedicated sampling equipment will be cleaned using an Alconox® detergent wash and potable water rinse prior to commencement of the project and between collection of each sample. Soil cuttings will be scattered unless there is field evidence of contamination, in which case the cuttings will be containerized onsite. Purge and development water will be containerized onsite. 5 Groundwater Monitoring Plan High Plains Disposal Weld Site#1 Kersey, Colorado Terracon Project No. 20097021 April 2009 4.0 GROUNDWATER MONITORING Quarterly groundwater monitoring will be conducted during the first 2 years. If there is no evidence of groundwater impacts after 2 years, High Plains will request to have the monitoring frequency reduced to semiannual. 4.1 Sampling Method During each round of sampling, depths to groundwater will be measured. A minimum of three well volumes will be purged from each well using a disposable bailing device, and in situ temperature, pH, and conductivity will be measured and recorded during the purge process. Following purging, a groundwater sample will be collected using a disposable bailing device and will placed in laboratory-supplied, pre-cleaned sample containers. Samples will be preserved in a cooler on ice. Following completion of sampling, the samples will be submitted to a qualified analytical laboratory under chain of custody protocol. 4.2 Laboratory Analysis COGCC adopted final amended regulations in April 2009 regarding allowable soil and groundwater contamination (COGCC Regulation 908, Table 910-1). For groundwater monitoring purposes, groundwater samples from the site will be analyzed for the parameters listed in COGCC Table 910-1. These parameters and the associated laboratory methods are shown below. Contaminant Laboratory Analytical Method Benzene EPA Method 8260 Toluene EPA Method 8260 Ethylbenzene EPA Method 8260 Xylenes EPA Method 8260 Total Dissolved Solids (TDS) EPA Method 160.1 Chloride EPA Method 300.0 Sulfate EPA Method 300.0 6 Groundwater Monitoring Plan High Plains Disposal Weld Site #1 Kersey, Colorado Terracon Project No. 20097021 April 2009 4.3 Statistical Analysis Groundwater analytical results will be evaluated statistically. A descriptive statistical analysis (number of data points, number of non-detectable data points, mean, maximum, minimum, standard deviation, and description of outliers) will be performed for each sample set. The trend analyses will be performed using the Mann-Kendall test and Sen's slope estimator. Using the Mann-Kendall test, a trend is significant at a 95% confidence level (two-tailed) if the absolute value of the Mann-Kendall statistic is greater than or equal to the absolute value of the critical value. A minimum of 7 rounds of data will be required to assess the accurately the analysis trends. If a statistically significant increase in concentrations of one or more target analytes is observed, the release reporting procedures discussed in Section 5.0 will be followed. 4.4 Reporting A summary groundwater monitoring report will be prepared and issued within 60 days of each sampling event. The report will provide a summary of sampling activities, tables with groundwater elevations and laboratory results, and figures including a groundwater piezometric map. Weld County will be provided with a copy of each quarterly report within 60 days of the sampling. 5.0 RELEASE RESPONSE ACTIONS If groundwater monitoring and assessment indicates a potential release from the facility, High Plains will notify Weld County within 24 hours of completing the statistical analysis of final laboratory analytical results. If the statistical analysis indicates a potential impact to groundwater by Oil & Gas Exploration & Production Waste (E&P Waste) and Produced Fluids (as defined by CDPHE's "Reporting Environmental Releases In Colorado" guidance document dated January 2009), High Plains will also report the release to COGCC and CDPHE within 24 hours of receiving the statistical analysis of final laboratory analytical results. High Plains will coordinate with these agencies to assess the site issues and potential release. This plan may be updated to reflect response actions if required. 7 Appendix A Figures 0 Z IT � ( • ' 1-- IV •i ( `' __,'" 4 .- - .4) \� �. / I i Q � 1 _.

(Terracon) has prepared the attached Air Pollutant Emission Notice (APEN) and supporting information regarding air emission estimates for the High Plains Disposal Weld Site#1 located in Kersey, Colorado. Terracon understands that volatile organic compound (VOC) mass emission rates in excess of five tons per year will require an Air Permit, issued by the Colorado Department of Public Health and Environment Air Pollution Control Division (APCD). Mr. Andy Cunningham of High Plains Disposal, shall be listed as the legal authorized person for the APEN and the Air Permit for this facility. FACILITY INFORMATION The High Plains Disposal Weld Site#1 (Facility) is located southwest of the intersection of Weld County Roads (WCR) 49 and 54 near the Town of Kersey and is geographically situated in the Northeast Quarter of the Northwest Quarter of Section 25, Township 5 North, Range 65 West of the 6th Principle Meridian, Weld County, Colorado. The Facility receives waste water from oil and gas exploration and production (E&P), processes the waste water, and disposes of processed water via its Class II injection well. As part of the disposal process, the facility separates waste water (brine) from crude oil hydrocarbons/condensate (product). Separated brine (Class II waste) is then injected into the Lyons formation through the HPD Kersey I wellbore, and the recovered product is stored onsite in aboveground storage tanks (ASTs) for subsequent sale. The facility has been permitted in accordance with the rules and regulations of the Colorado Oil and Gas Conservation Commission (COGCC) and is scheduled for construction in 2009. The proposed waste water treatment system consists of a covered unloading area, receiving pit, two "gun barrel" separator tanks, six post-process water storage tanks, two product tanks, a pump house, an injection well, and other associated processing equipment. Tanks, pumps, and associated process equipment are connected by carbon steel piping, valves, and other connections.. The injection pumps, transfer pumps, and other mechanical equipment at the Facility are powered by electricity. Attachment 1 contains figures showing site layout, process areas, and storage tanks.

The average crude/condensate product volume in the received liquids to the waste water treatment system is expected to be approximately 2% to 3% by volume. The Facility will operate 365 days per year and will start operations in 2009. EMISSION COMPONENTS Emission related equipment for the facility consists of ASTs and separator equipment. Facility ASTs are summarized in the following table. ID No. Name Size (BBL) T-1P Product 750 T-2P Product 750 T-1S Separator 600 T-2S Separator 600 T-1W Water 750 T-2W Water 750 T-3W Water 750 T-4W Water 750 Additional information is provided on Tables 1 and 2 in Attachment 2. Emission related processes for the Facility consists of"load in" of E&P waste water (Class II waste) and "load out" of product. Estimated VOC Emissions Terracon has estimated annual VOC emissions from the ASTs and the load in/load out processes. The following paragraphs review the basis and assumptions for the emission rate estimates. For emission calculations, Terracon has assumed the following: • Emissions calculations are based on a production rate of 10,000 bbl/day throughput with a 3% condensate cut. • 100% of the condensate is separated from the water and stored in the condensate tanks. • Post-processing water storage tanks reportedly have a low petroleum con centration and VOC emissions from these tanks are assumed to be negligible. 2 High Plains Disposal Weld Site#1 Terracon APEN Submittal Terracon Project No. 20097021 April 14, 2009 • Load-in emissions are assumed to be identical to load out emissions and calculated using emission factors and equations listed in U.S. Environmental Protection Agency's (EPA) Compilation of Air Pollutant Emission Factors (AP- 42). Load-in and load-out emissions are based on bottom-loading processes. • Emissions from the "gun barrel" separator tanks are assumed to be an integral component of the emissions from the product ASTs and have not been calculated separately. Assumptions for the water ASTs, loading emissions, and "gun barrel" separators were made based on a telephone conversation with Mr. Adam Wozniak of the APCD in February 2009. Product and Separator ASTs: The estimated VOC emissions from the four product ASTs was completed using the EPA TANKS 4.0.9d software (TANKS). TANKS is a Windows-based computer software program that estimates VOC and hazardous air pollutant (HAP) emissions from fixed- and floating-roof storage tanks. TANKS is based on the emission estimation procedures from Chapter 7 of EPA's AP-42. For the TANKS calculations, the meteorological data for the Denver, Colorado region yielded an estimate of approximately 75 throughputs per year per product AST, with crude oil for the tank contents. TANKS does not provide an option of "condensate" for tank content, and crude oil is the closest available match in TANKS to the product stored at the subject site. Additional input data is included with the TANKS 4.0.9d Emissions Report in Attachment 3. Emissions from the product ASTs and "gun barrel" separators are estimated to be approximately 5.14 tons per year. Water ASTs: Following the separation process through the 'gun barrel tanks', the water stored in the ASTs reportedly has a low concentration of VOCs. Emissions from these tanks are assumed to be negligible. Load In/Out Emissions: VOC vapor emission calculations for load in of E&P waste water (Class II waste) and load out of recovered product are based on procedures from Chapter 5 of EPA's AP-42. The load-in and load-out emissions were calculated assuming the use of bottom loading. 3 High Plains Disposal Weld Site#1 Terracon APEN Submittal Terracon Project No. 20097021 April 14, 2009 Combined load in/out emissions are estimated to be approximately 4.63 tons per year. Loading emission estimates, including equations and calculations, are presented on Table 3 in Attachment 2. Total Estimated Facility Emissions: Total estimated emissions from the Facility are estimated to be approximately 14.4 tons per year. A Facility Emission Estimate Summary is presented in Attachment 2, Table 4. Additional data, including the VOC annual requested permit level, are included with the APEN, Supplement APENs, and other supporting materials in Attachment 3.
