(Western)was requested to redrill and retest soil from a quarterly sampling event location originally conducted on October 2, 2007. During the recent quarterly sampling event completed at the site, the Soil Boring 1 location contained trace concentrations of BTEX compounds. This is the first detection of BTEX compounds documented at the facility. SOIL SAMPLING AND TESTING To ensure that hydrocarbon compounds do not migrate vertically into native soil, quarterly soil and ground water sampling is performed at the facility. All ground water samples obtained during the October 2, 2007 event tested clean for both BTEX and TRPH compounds. Nine of ten subsurface soil samples also did not contain any measurable concentrations of these compounds. However, the soil sample obtained from the northeast corner of the active soil treatment area, identified as sample #SB1-5', did contain trace concentrations of total Toluene, Ethylbenzene and Xylene compounds. No soil quality soil standards were exceeded. The SB1-5' sample acquired on October 2, 2007, contained the following: Toluene 6.3 µg/Kg (ppb) Ethylbenzene 2.8 mg/Kg (ppb) Xylene 5.8 mg/Kg (ppb) Western Cleanup Corporation of Fort Morgan, Colorado performed site drilling tasks for this project. Soil placed into the treatment pad area was first removed to expose native soil at original site grade. The original location of the SBI boring was located. An offset location was drilled immediately adjacent to the first location. Drilling of the SB 1 A soil test boring was performed using a Hurricane probe drill rig. A soil core was recovered inside of a new core barrel butyl liner. Drilling and sampling equipment were cleaned prior to re-use. The rig uses the direct hydraulic push technique to advance a core barrel sampler to the desired depth below original grade. Soil samples were obtained from a depth of 5 feet and 10 feet. The test boring was then backfilled to grade with bentonite chips. Each recovered soil core interval was examined. Each core interval was tested in the field using a calibrated Photoionization detector instrument via the head space test method. There were no volatile gasses present in the soil samples. Each soil sample was immediately labeled and cooled. All soil samples were acquired using laboratory chain-of-custody documentation. Samples were submitted to Technology Laboratory, located in Fort Collins, Colorado. A total of two soil samples were analyzed. Each soil sample was analyzed for Total Recoverable Petroleum Hydrocarbons (TRPH) and Benzene, Ethylbenzene, Toluene and Xylene (BTEX) compounds. US EPA preparation and analytical Method #418.1 was used for the TRPH analyses. Soil samples were also tested for BTEX compounds using EPA Method#8260B. A summary table of test results from the quarterly event conducted on October 2, 2007 and the retesting completed on October 24, 2007 is attached. A map indicating the location of the SB I A test boring is also attached. Retesting of soil from a depth of 5 and 10 feet below grade did not detect any BTEX or TPH compounds to be present at the drill location. The next quarterly site monitoring event is scheduled to be conducted the week of December 30, 2007. Please contact us with any questions which you may have.

(Western) has completed a sixth scheduled quarterly testing event at the subject facility. The facility receives petroleum soil from exploration and production sites. The land farm treats and then recycles remediated petroleum soil. Quarterly sampling of soil within treatment areas of the land farm is required. In addition, ground water monitoring is also to be conducted during each quarter of facility operation, and until final site closure. SOIL SAMPLING AND TESTING Quarterly soil sampling and testing is conducted to ensure that hydrocarbons present in active soil treatment areas do not migrate into underlying native soil. Western personnel mapped and measured the petroleum soil stockpile areas. A grid was prepared and drilling locations marked on the site. The south half of the facility was receiving and treating soil at the time of this quarterly testing event. A large front end loader was then used to clear petroleum soil from treatment areas. Petroleum soil was removed deep enough to expose the original surface of native soil. Drilling began in native soil. Western Cleanup Corporation of Fort Morgan, Colorado performed site drilling and excavating tasks. Drilling of soil test borings was performed using a Hurricane probe drill rig. The rig uses the direct hydraulic push technique to advance a core barrel sampler to the desired depth of 5 feet below original grade. A soil core is then recovered inside of a new core barrel butyl liner. Drilling and sampling equipment are cleaned prior to re-use. Each recovered soil core interval is examined. Soil types are recorded. Each interval is tested in the field using a calibrated Photoionization detector instrument via the head space test method. In quarterly sampling events, soil samples are obtained from a depth of 5 feet below original site grade. Soil samples were described by a professional geologist. Subsurface soil samples were obtained while drilling. Each soil sample is immediately labeled and cooled. All soil samples were acquired using laboratory chain-of-custody documentation. Samples were submitted to Technology Laboratory, located in Fort Collins, Colorado. A total of ten soil samples were analyzed. Each soil sample was analyzed for Total Recoverable Petroleum Hydrocarbons (TRPI-I) and Benzene, Ethylbenzene, Toluene and Xylene (BTEX) compounds. US EPA preparation and analytical Method#418.1 was used for the TRPH analyses. Soil samples were also tested for BTEX compounds using EPA Method#8260B. A summary table of current and historical soil test results is attached. Laboratory test and QA/QC data is also attached. Soil cores recovered during the test drilling consisted of tight silts, clays and sands. There was no visual hydrocarbon staining observed in the test soil core samples recovered. There were trace BTEX compounds detected in soil from the SBI boring area. There were no TRPI1 petroleum hydrocarbons detected in any of the ten subsurface soil samples analyzed. GROUND WATER SAMPLING AND TESTING The permit for the facility also requires quarterly surveys and testing of site ground water. Six permanent stick-up ground water monitoring wells have been installed in areas outside of the active soil treatment pad. The wells were completed into underlying bedrock shale. Ground water flows due west at the site. An elevation survey was completed on each well to determine reference elevations for water surveys. The locations of monitor wells are presented on an attached map. An electronic water level was used to measure static water elevations in all wells prior to sampling. A new disposable well bailer is used to purge and sample monitor wells. Normally, a minimum of three wellbore volumes of ground water is removed from the wells to obtain representative ground water samples for laboratory testing. New sampling line and surgical gloves were used when obtaining ground water samples. Each sample is obtained using laboratory chain-of-custody documentation. Only three of the site wells contained measurable ground water during this event. Ground water samples were placed into 40 ml VOA vials and immediately labeled. Ground water samples were submitted to Technology Laboratory for testing. EPA preparation and test Method #418.1 was used to test ground water samples for TRPH compounds. Ground water samples were prepared and tested for BTEX compounds using EPA Method #8260B. There were no BTEX of TRPH compounds detected in ground water samples. An analytical summary table for ground water testing is attached. QUARTERLY MONITORING SUMMARY There were no BTEX or TRPH compounds detected in site ground water samples obtained for this event. One of ten soil samples tested from beneath active soil treatment areas did contain trace amounts of BTEX compounds. The area near the SB1 boring will be re-drilled and tested again in the near future. No soil or ground water standards of the state were exceeded in site soil or ground water samples analyzed. The next quarterly site monitoring event is scheduled to be conducted the week of December 30, 2007. Please contact us with any questions which you may have.

MENT FACILITY, lICOUNTY, COLORAD SPECIAL USE PERMIT #1517 Western Project #05206 May 21, 2007 Dear Mr. Jiricek: Western Environmental Technologies, Inc. (Western) has completed an additional quarterly testing event at the subject facility. The facility receives, treats and recycles remediated petroleum soil. Quarterly sampling of soil within treatment areas of the land farm is required each quarter of facility operation. SOIL SAMPLING AND TESTING Quarterly soil sampling and testing is conducted to ensure that hydrocarbons present in active soil treatment areas do not migrate into underlying native soil. The petroleum soil deposited for remediation treatment range from silts to cobbles in size. Native soil which underlies treatment areas are generally tight silts and very fine sand. In accordance with an approved site monitoring plan, the configuration of active treatment areas was mapped. A sample grid was prepared to identify test drilling locations. Heavy equipment removed petroleum contaminated soil from 10 selected drilling sites. Petroleum soil was removed deep enough to expose the surface of native soil. Western Cleanup Corporation of Fort Morgan, Colorado performed excavating and site drilling tasks. Drilling of soil test borings was performed using a Hurricane probe drill rig. The rig uses the direct hydraulic push technique to advance a core barrel sampler to the desired depth. A soil core is then recovered inside of a new core barrel butyl liner. Drilling and sampling equipment are cleaned prior to re-use. Each soil interval is examined. Soil types are recorded. Each interval is tested in the field using a calibrated Photoionization detector instrument. In quarterly sampling events, soil samples are obtained from a depth of 5 feet below original site grade. Each soil sample is immediately labeled and cooled. All soil samples were acquired using laboratory chain-of-custody documentation. Samples were submitted to Technology Laboratory, located in Fort Collins, Colorado. A total of ten soil samples were analyzed. Each soil sample was analyzed for Total Recoverable Petroleum Hydrocarbons (TRPH) and Benzene, Ethylbenzene, Toluene and Xylene (BTEX) compounds. US EPA preparation and analytical Method#418.1 was used for the TRPH analyses. Soil samples were also tested for BTEX compounds using EPA Method#8260B. A summary table of test results is attached. Laboratory test and QA/QC data is also attached. Soil cores recovered during the test drilling consisted of tight silts, clays and sands. There was no visual hydrocarbon staining observed in the test soil core samples recovered. There were no Benzene, Toluene or Ethylbenzene compounds detected in the soil samples. All soil core samples were within allowable soil quality limits of Colorado Dept of Public Health & Environment - Water Quality Control Commission (WQCC). GROUND WATER SAMPLING AND TESTING The permit for the facility also requires quarterly surveys and testing of site ground water. Six permanent stick-up ground water monitoring wells have been installed in areas outside of the active soil treatment pad. The wells were completed to bedrock. An elevation survey was completed on each well to determine reference elevations using USGS datum to determine sea level elevations of well reference points. The locations of monitor wells are presented on an attached map. An electronic water level was used to measure static water elevations in all wells prior to sampling. A new disposable well bailer was then used to purge and sample monitor wells. A minimum of three wellbore volumes of ground water was removed to purge water from wells and obtain a representative ground water for laboratory testing. New sampling line and surgical gloves are used when obtaining ground water samples. Ground water flows southwest at the site. Each sample is obtained using laboratory chain-of-custody documentation. Only three of the site wells contained measurable ground water during this event. Ground water samples were placed into 40 ml VOA vials and immediately labeled. Ground water samples were submitted to Technology Laboratory for testing. TRPH samples were placed into one liter amber glass containers and immediately cooled. EPA preparation and test Method #418.1 was used to test ground water samples for TRP11 compounds. Ground water samples were prepared and tested for BTEX compounds using EPA Method#8260B. There were no BTEX of TRPH compounds detected in ground water samples. An analytical summary table is attached. QUARTERLY MONITORING SUMMARY There were no BTEX or TRPH compounds detected in site ground water samples obtained for this event. Three of the ground water monitoring wells were dry. Ground water levels have increased by approximately 4 feet since the last testing event in February, 2007. Soil tested from beneath active treatment areas did not contain measurable amounts of Benzene, Toluene or Xylene compounds. No TRPH compounds were detected in native soil underlying active treatment areas. No elevated head space measurements were observed when field screening subsurface soil samples. All site samples tested within environmental quality standards of the WQCC. The next quarterly site monitoring event is scheduled to be conducted the week of August 26, 2007.

Littleton Boulevard * Littleton, Colorado 80120 * 303-7' - a ' . *3-795-774 Mr. Trevor Jiricek, M.A. Director - Environmental Health Services Weld County Department of Public Health & Environment 1555 North 17th Avenue ©CD py Greeley, Colorado 80631 OUARTERLY MONITORING REPORT, FEBRUARY - 2007, PETRO-CANADA KERSEY SOIL TREATMENT FACILITY, WELD COUNTY, COLORADO SPECIAL USE PERMIT #1517 Western Project#05206 February 22, 2007 Dear Mr. Jiricek: Western Environmental Technologies, Inc. (Western) has completed a fourth scheduled quarterly testing event at the subject facility. The facility receives petroleum soil from exploration and production sites. The land farm treats and then recycles remediated petroleum soil. Quarterly sampling of soil within treatment areas of the land farm is required. In addition, ground water monitoring is also to be conducted during each quarter of facility operation, and until final site closure. SOIL SAMPLING AND TESTING Quarterly soil sampling and testing is conducted to ensure that hydrocarbons present in active soil treatment areas do not migrate into underlying native soil. The testing event originally scheduled to be conducted the week of December 25, 2006 had to be postponed. Severe weather and large snow accumulations prevented access to necessary areas for surveys and testing. A large front end loader was used to clear snow for test drilling and remove stockpiled petroleum soil from the treatment areas during this monitoring event. As much as 4' of snow still covered some portions of the site when testing was conducted. In accordance with an approved site monitoring plan, the configuration of active treatment areas was mapped. A soil sample location grid was then prepared to identify test drilling locations. Heavy equipment removed petroleum contaminated soil from 10 selected drilling sites. Petroleum soil was removed deep enough to expose the original surface of native soil. Western Cleanup Corporation performed site drilling and excavating tasks. Drilling of soil test borings was performed using a Hurricane probe drill rig. The rig uses the direct hydraulic push technique to advance a core barrel sampler to the desired depth of 5 feet below original grade. A soil core is then recovered inside of a new core barrel butyl liner. Drilling and sampling equipment are cleaned prior to re-use. Each recovered soil core interval is examined. Soil types are recorded. Each interval is tested in the field using a calibrated Photoionization detector instrument via the head space test method. In quarterly sampling events, soil samples are obtained from a depth of 5 feet below original site grade. After drilling in test locations, all test borings were backfilled with bentonite chips. Each soil sample is immediately labeled and cooled. All soil samples were acquired using laboratory chain-of-custody documentation. Samples were submitted to Technology Laboratory, located in Fort Collins, Colorado. A total of ten soil samples were analyzed. Each soil sample was analyzed for Total Recoverable Petroleum Hydrocarbons (TRPH) and Benzene, Ethylbenzene, Toluene and Xylene (BTEX) compounds. US EPA preparation and analytical Method#418.1 was used for the TRPH analyses. Soil samples were also tested for BTEX compounds using EPA Method#8260B. A summary table of current and historical soil test results is attached. Laboratory test and QA/QC data is also attached. Soil cores recovered during the test drilling consisted of tight silts, clays and sands. There was no visual hydrocarbon staining observed in the test soil core samples recovered. There were no BTEX or TRPH petroleum hydrocarbons detected in any of the ten subsurface soil samples analyzed. GROUND WATER SAMPLING AND TESTING The permit for the facility also requires quarterly surveys and testing of site ground water. Six permanent stick-up ground water monitoring wells have been installed in areas outside of the active soil treatment pad. The wells were completed into underlying bedrock shale. Ground water flows due west at the site. An elevation survey was completed on each well to determine reference elevations for water surveys. The locations of monitor wells are presented on an attached map. An electronic water level was used to measure static water elevations in all wells prior to sampling. A new disposable well bailer is used to purge and sample monitor wells. Normally, a minimum of three wellbore volumes of ground water is removed from the wells to obtain representative ground water samples for laboratory testing. However, two of the wells tested to contain little water column and did not yield the desired volume of purge water. New sampling line and surgical gloves are used when obtaining ground water samples. Each sample is obtained using laboratory chain-of-custody documentation. Only three of the site wells contained measurable ground water during this event. Ground water samples were placed into 40 ml VOA vials and immediately labeled. Ground water samples were submitted to Technology Laboratory for testing. EPA preparation and test Method #418.1 was used to test ground water samples for TRPH compounds. Ground water samples were prepared and tested for BTEX compounds using EPA Method #8260B. There were no BTEX of TRPH compounds detected in ground water samples. An analytical summary table is attached. QUARTERLY MONITORING SUMMARY There were no BTEX or TRPH compounds detected in site ground water samples obtained for this event. Soil tested from beneath active treatment areas did not contain measurable amounts of BTEX or TRPH compounds. Soil and ground water quality standards of the WQCC have not been exceeded in media samples tested. Although this event would have constituted the first annual event for this site, Western was informed to conduct the event the same as planned quarterly events. Western was informed not to drill beyond 5 feet in depth from original grade for this event. The next quarterly site monitoring event is scheduled to be conducted the week of May 20, 2007.

The purpose of the review was to determine if Petro has addressed all Health Department related conditions. Based upon my review of the file, it did not appear that Petro has addressed Conditions of Approval 1.D., G., H., or I. I contacted Sherri Robbins concerning these conditions. She indicated that she had submitted materials to address each item previously.

Dear Mr. Jiricek: Please find enclosed the Stormwater Protection Certification for the Centralized Land Treatment Facility. The certification was requested by Mr. Troy Swain of your department. A copy has been sent to Mr. Kim Ogle, of Weld County Planning &Zoning, as well as to Mr. Randall Ferguson of the Colorado Oil and Gas Conservation Commission. I believe the one outstanding item for our Resolution is the APEN. As you know, the initial APEN was submitted to the CDPHE in January 2006. Additional information has been requested by the CDPHE, which Petro-Canada has provided. To date, I still have not received any correspondence from the CDPHE. Would it be possible to waive the APEN for the purpose of recording the plat? Mr. Ogle is aware of the situation with the CDPHE and the fact that the APENs are taking 9-12 months to process. It is imperative that we record the plat for the Centralized Land Treatment facility as Petro-Canada is in the process of submitting another USR application with Weld County in order to move our LaSalle field office. We are not able to submit the application until the landfarm has been finalized and permitted. I would appreciate your consideration of the matter and I look forward to receiving your response. Please do not hesitate to contact me at 303-350-1180 if I can provide additional information or answer any questions that you may have as a result of this letter.

One question that I had was on whether a 60% biodegradation efficiency can be achieved. The reason I question it is due to the fact that condensate has high volatilization and the report may have been based on land farming of gasoline (less volatile) . I think the best 1 thing would be if I could get a copy of the Assessment of Air Emissions From a Laboratory Land Treatment Facility (or at least the most relavent pages) . This should assist me in verifying the biodegradation efficiency. Thanks ! ! Jon >>> "Denise (CBeyond) " <denisek@lesair.com> 04/25/06 7 :44 AM >>> Jon, Hi my name is Denise Kohtala I work with Lesair Environmental, we prepared a APEN submittal for the Petro-Canada land treatment facility back in January of this year. I noticed from the CDPHE website that you are the permit engineer for this application and was hoping you could update me on the status of the application! Thanks for your help!

Hancock Colorado Department of Public Health&Environment Air Pollution Control Division 4300 Cherry Creek Drive South,APCD-SS-B1 Denver,Colorado 80246-1530 RE: 06WE0038: Revised APEN Submittal Centralized Land Treatment Facility Weld,Colorado Petro-Canada Resources(USA) Inc. Dear Mr. Hancock: Petro-Canada Resources (USA) Inc (Petro-Canada), is submitting the requested RACT analysis and a revised APEN for the Centralized Land Treatment Facility located in the NENWNW of Section 18,T4N, R64W of Weld County. The Colorado Oil and Gas Conservation Commission (COGCC) Rule 910 requires that remediated soils be treated for TPH to a minimum of 1,000 ppm. Based on this rule, emissions were calculated by subtracting 1,000 ppm TPH from the actual inlet soil TPH resulting in the amount of TPH that is of concern. It was also assumed that 100%of the TPH is volatile organic carbons. Appendix D includes the Table 910-1 stating the allowable TPH concentrations for soil. As explained in the original application the first year of operation will have a soil throughput of approximately 20,000 cubic yards. This is due to two large clean-up activities. The soil throughput of the facility for the remaining years of operation is expected to be approximately 2,000 cubic yards or less. It was estimated that 15%of the soil has a TPH concentration of 6,000 ppm and that the remaining 85% of the soil has a concentration of 1,200 ppm. Initial emissions estimations were calculated based on 40% of the TPH volatilizing and the remaining 60% biodegrading. This volatilization fraction was based on research that shows that 13%to 66% of the existing volatiles will be emitted to the atmosphere in typical land treatment facilities. This data was based on a report titled Assessment of Air Emissions from a Laboratory Land Treatment Facility. A median value of 40% was used for the fraction of TPH that would volatize in the initial emissions calculations. An assessment of the properties of the condensate was conducted to better understand the potential to remove the contaminating hydrocarbons. Based on soil analyses approximately 30% of the hydrocarbons are similar to gasoline and the remaining 70% of the TPH is similar to diesel fuel. Gasoline and lighter hydrocarbons tend to volatize quickly and heavier hydrocarbons like diesel fuel tend to be slower to volatize. Combining this information with the results of the previously noted report allowed for a more detailed and accurate estimation of the VOC emissions. Suite 400,1099 18th Street • Denver,CO 80202-1904 Office:(303)297-2300 • Fax(303)297-7708 • www.petro-canada.ca Petro-Canada(USA)Resources,Inc. Centralized Land Treatment Facility APEN Submittal Page 2 of 2 Emissions were recalculated assuming that 100% of the gasoline constituents volatilize and 50% of the diesel constituents volatilize. Diesel fuel having heavier components will be broken down slower. It was assumed that 50% will volatize and 50%will biodegrade. A value of 50% volatizing was used from the previously mentioned report. A 50% volatization rate is being assumed instead of 40% to allow for a more conservative emissions estimate. The estimated VOC emissions from the first year of operation were calculated to be 7.0 TPY and for every year after that they were calculated to approximately 1.32 TPY. These estimations reflect the above mentioned partitioning of the condensate into gasoline and diesel constituents. As mentioned above 50% of the diesel fuel will remain in the soil and the remaining hydrocarbons will emit VOC as they volatize to the environment. These conditions are reflected in the calculations for Appendix B. The enclosed RACT analysis examined the cost to control the emissions from the facility using soil burning technology. Below is a brief description of two possible emission cases; for more detailed calculations and explanations see the accompanying appendices. • Appendix A: 100%Volatization of all Hydrocarbons 100%of both diesel and gasoline constituents volatize Emissions were averaged over the ten years then the RACT was conducted • Appendix B: 50-50 Biodegradation-Volatization of Diesel Constituents 100%of gasoline constituents volatize 50% of the diesel constituents will volatize and 50% will remain in soil for biodegradation Emissions were averaged over the ten years then the RACT was conducted The cost of various soil burning units can be found in Appendix C. The cost to purchase the equipment ranged from$350,000.00 to $525,000.00, as such the RACT was evaluated at an average of$450,000.00. Based on the RACT analysis Petro-Canada has determined that the cost to control is not economically reasonable. Enclosed are a revised APEN, the requested RACT analysis, and the revised facility emissions.

The results of the comparison showed that the contaminant,condensate was similar to both gasoline and to diesel fuel and could not be treated just as a gasoline or diesel hydrocarbon. Soil samples were taken of the contaminated soil and their results showed that the contamination was approximately 30%gasoline constituents and 70%diesel constituents. The calculations below reflect the emissions from both types of sources. In all cases the gasoline portion is assumed to volatize 100%.

(Western) is submitting a revised proposed plan for the monitoring of area subsurface soil and for the periodic monitoring of ground water. Western personnel have obtained and analyzed thousands of water, soil and waste samples at release sites throughout the Rockies and I Ugh Plains Regions. Western personnel have prepared and executed many environmental monitoring and cleanup plans at operational facilities and cleanup sites for both government and industry. This plan has been developed after reviewing operational conditions stipulated in permit documents. The permit for the landfarm facility requires certain testing schedules and response plans be in-place to operate the facility. Petro-Canada Resources, Inc. shall utilize the landfarm facility to remediate petroleum contaminated soil. Only exploration and production derived impacted soil will be treated at the facility. The proposed monitoring plans are designed to quickly detect a release of certain petroleum compounds into ground water and soil underlying and adjacent to the facility. If a release of petroleum compounds occurs in soil or ground water, plans must be formulated to assess and remediate the release. QUARTERLY GROUND WATER MONITORING PLAN There are currently six permanent ground water monitoring wells surrounding the active areas of the landfarm facility. The network of wells installed at the site are located outside of the soil stockpile areas. During each quarterly testing event, ground water elevation levels and other parameters will be surveyed. All test and survey equipment will be decontaminated before each use. All drilling and site assessment personnel potentially in direct contact with site waste will he ()S1-IA certified for I lazardous Waste Operations. I • • A minimum of three wellbore volumes of ground water will he purged from each well, or the wells purged dry, prior to sampling. Each ground water sample will be obtained from the wells using a new disposable well bailer. Samples will be acquired using new surgical gloves and line. All ground water sample containers will immediately be labeled and cooled. All ground water samples will be obtained using laboratory chain-of-custody documentation. Samples will he delivered to a certified analytical laboratory. Technology Laboratory of Fort Collins, Colorado will perform the requested analyses utilizing US EPA preparation and test methods. Each ground water sample will be analyzed for Total Petroleum Hydrocarbons (TPH) using EPA analytical Method #418.1. All ground water samples will also be analyzed for Benzene, Toluene, Ethylhenzene and Xylene (BTEX) compounds using US EPA Method #8015 Modified, or via Method #8021 as required by the facility operator. Analytical report summaries and QA/QC data shall be provided for all testing. Quarterly ground water monitoring reports will be prepared and submitted to the Colorado Oil & Gas Conservation Commission (OGCC) and to the Weld County Department of Public Health Environment 1 WCDPHE). Quarterly reports will also include ground water elevation contour maps for each testing event. Quarterly sampling and reporting will be performed in accordance with permit requirements. GROUND WATER RELEASE ASSESSMENT PLAN If any detections of BTEX or TPI-I compounds are documented in ground water, an assessment plan will immediately he prepared. It may he necessary to install additional wells for documenting the source area of a detected release into underlying ground water. If a ground water release does occur, a plan to control or remediate ground water will also be submitted. QUARTERLY SOIL MONITORING PLAN Quarterly subsurface soil samples will be obtained from directly within the active landfartn area. Petroleum soil would be removed from ten selected sample locations. The sample locations will be on a grid pattern. A probe type drill rig would be used to obtain soil samples from a depth below the site surface of 3 feet. I ach soil sample would be retrieved within a new core barrel for recovery and testing. All drilling and sampling equipment will be properly decontaminated prior to each new test location. Alternately, an auger type drilling rig could also be used to obtain quarterly soil samples. Each soil sample would be obtained using laboratory chain-of-custody documentation. All samples will be submitted to Technology Laboratory located in Fort Collins, Colorado. Soil samples will be tested for TPH using 1 :5 EPA Method #418.1. Soil samples will also he analyzed for BTEX compounds via US EPA Method #8015 Modified. Results of soil testing will be reported to the OGCC and WCDPI-IE each quarter. Quarterly reports will include all laboratory data as well as test boring location maps and other appropriate figures or diagrams. ANNUAL SOIL TESTING Annual soil sampling will also be performed. During the annual testing, an auger type drill rig. such as a C'ME 75 drill rig, would be used to advance test borings. Soil samples would be obtained from a minimum of ten test locations. Soil samples will be obtained from five, ten. fifteen and twenty foot depth intervals. At least ten test soil borings will be drilled and tested each year of operation. The locations of test borings will be within the active stockpiled soil areas. Testing of soil will be performed using a grid pattern. Petroleum soil stockpiles will first be removed from selected test areas to permit access to the areas by a drilling rig. Stockpiled soil will be removed to restore the test locations to near original grades. This will permit sampling of underlying native soil to access whether a ',lease to underlying soil has occurred from soil being treated. Soil core samples will be obtained from the test locations using a 5 foot continuous split-barrel core sampler. All drill tools and sample barrel samplers will be decontaminated prior to each use or new boring. Each boring will be logged by a Professional Geologist. Head space testing of recovered soil cores v ill be perlonned in the field using a calibrated Photoionization Detector. A soil boring log will he prepared for each annual test boring. The location; of test borings will also be indicated on maps prepared for each annual testing event. SOIL RELEASE ASSESSMENT AND CORRECTIVE ACTION PLAN In addition to quarterly reports, an annual soil testing report will also be submitted to the OGCC and WCDI'f lE. If a release of BTEX or TPH compounds is documented at a depth greater than 5 feet below the surface of the site, a plan to further assess the release to soil would be immediately prepared and submitted. The plan may require the installation of additional test soil borings to define the source area of the released hydrocarbons. Once the source and extent of a petroleum release is documented, a plan to remediate the release will also be developed and submitted for approval. The plan may stipulate soil removal, in-situ soil treatment or some other method of remediating soil which is impacted above permissible limits with I3TEX and/or TPH compounds. REMEDIATION PROGRESS SAMPLING During the treatment of petroleum contaminated soil in the landfarm area, periodic sampling may be conducted. Representative soil samples will be analyzed for BTEX and TPH compounds to document §,iodegradation progress of soil being treated. More aggressive treatment may be recommended for portions of the landfarm which contain heavier hydrocarbons, that do not generally il. grade as quickly as lighter hydrocarbon wastes. CHARACTERIZING INCOMING WASTE SOIL The landfarm may accept maximum volumes of petroleum contaminated soil based upon the concentrations of TP11 compounds in different waste streams. It is recommended that TPH laboratory analyses of waste soil be performed to document the concentrations of petroleum soil delivered for treatment at the facility. Sampling and testing of incoming soil will be performed to document soil contaminants generated at different site locations. Records of test data will be maintained for a period of at least three years. CHARACTERIZING INCOMING FRAC SAND WASTE Occasionally, the facility may accept frac sand waste generated from well stimulation treatments. Approximately 1,000 cubic yards of sand waste may he treated at the facility per year, or as stipulated in the facility operating permit. The frac sand waste will be tested for specified compounds. TESTING OF SOIL TO BE RECYCLED Before the operator may recycle treated soil from the facility, field screening will be performed using a calibrated Photoionization Detector. Head space surveys will be conducted to determine which landfarm soil may be treated to standards. Additionally, samples of treated soil may be obtained. The treated waste soil samples will be analyzed for BTFX and TPH compounds using the prescribed EPA preparation and test methods. Sample locations will he identified on prepared maps. Soil must be treated to within sensitive area standards before being re-used in other locations. Waste testing results will be reported, as requested, to the OGCC and WCDPHE.

There are several issues regarding the contents of this correspondence as follows: > The Soil and Ground Water Monitoring Plan states that"... land treatment will be deemed complete when TPH/TRPH concentrations are determined to be below applicable concentration levels for the area in which the treated soil will be re-used." COGCC Response—The COGCC conditional approval letter for the facility dated June 17,2005 specifically states that remediated soils used as backfill and construction material at other Petro-Canada facilities must meet the criteria for sensitive areas in Table 910-1 regardless of the location of such facility(see attached copy of letter). > The Soil and Ground Water Monitoring Plan also states that"... ground water monitoring and sampling will switch to an annual basis following the collection of two consecutive semi-annual ground water samples that exhibit BTEX concentrations below COGCC allowable contaminant concentration levels." COGCC Response—The COGCC conditional approval letter for the facility dated June 17, 2005 specifically states that the switch to an annual basis is not approved(see attached copy of letter). > The Design and Operations Plan states that Petro-Canada anticipates treating 300-500 cubic yards(CY)of hydrocarbon-affected soil and a similar volume of frac sand on an annual basis. Additionally,the Air Pollutant Emission Notification(APEN) submission states that the soil throughput of the facility is expected to be approximately 1,000 CY per year.

Approximately 7,790 CY was transported from the Kammerzell site and an unknown volume from the Henry site. According to COGCC files,approximately 2,912 CY of hydrocarbon impacted soil has been excavated from seven other Petro-Canada remediation sites and transported to the subject facility.

(Western) is submitting a proposed plan for the monitoring of area subsurface soil and for the periodic monitoring of ground water. Western personnel have obtained and analyzed thousands of water, soil and waste samples at release sites throughout the Rockies and High Plains Regions. Western personnel have prepared and executed many environmental monitoring and cleanup plans at operational facilities and cleanup sites for both government and industry. This plan has been developed after reviewing operational conditions stipulated in permit documents. The permit for the landfarm faci'lty requires certain testing schedules and response plans be in-place to operate the facility. Petro-Canada Resources, Inc. shall utilize the landfarm facility to remediate petroleum contaminated soil. Only exploration and production derived impacted soil will be treated at the facility. The proposed monitorint' plans are designed to quickly detect a release of certain petroleum compounds into ground water .ind soil underlying and adjacent to the facility. If a release of petroleum compounds occurs lo soil or ground water, plans must be formulated to assess and remediate the release. IARTERLY GROUND WATER MONITORING PLAN There are currently six permanent ground water monitoring wells surrounding the active areas of the IandLirm facility. The network of wells installed at the site are located outside of the soil stockpile areas. During each quarterly testing event, ground water elevation levels and other parameters will be surveyed. All test and survey equipment will be decontaminated before each use. Ali drilling and site assessment personnel potentially in direct contact with site waste will he OSH: certified 'or Hazardous Waste Operations. • • A minimum of three wellbore volumes of ground water will be purged from each well, or the wells purged dry, prior to sampling. Each ground water sample will be obtained from the wells using a new disposable well bailer. Samples will be acquired using new surgical gloves and line. All ground water sample containers will immediately be labeled and cooled. All ground water samples will be obtained using laboratory chain-of-custody documentation. Samples will be delivered to a certified analytical laboratory. Technology Laboratory of Fort Collins, Colorado will perform the requested analyses utilizing US EPA preparatidn and test methods. Each ground water sample will be analyzed for Total Petroleum Hydrocarbons (TPFI) using EPA analytical Method #418.1. All ground water samples will also be analyzed for Benzene, Toluene, Ethylbenzene and Xylene (BTEX) compounds using US EPA Method #8015 Modified, or via Method #8021, as required by the facility operator. Analytical report summaries and QA/QC data shall be provided for all testing. Quarterly ground water monitoring reports will be prepared and submitted to the Colorado Oil & Gas Conservation Commission (OGCC) and to the Weld County Department of Public Health & Environment(WCDPIIE). Quarterly reports will also include ground water elevation contour maps for each testing event. If water quality remains within standards for a period of one year, the frequency of ground water testing may be reduced. GROUND WATER RELEASE. ASSESSMENT PLAN If ground water quality standards are exceeded during any quarterly monitoring event, an assessment plan will immediately be prepared. The operator may have to suspend operations at the landfarm until the extent of the ground water contamination and source area of the release is fully defined. It may be necessary to install additional wells for documenting the source area of a release into underlying ground water. If a ground water release does occur, a plan to control or remediate ground water will also be submitted. QUARTERLY SOIL MONITORING PLAN Quarterly subsurface soil samples will be obtained from directly within the active landfarm area. Petroleum soil would be removed from ten selected sample locations. The sample locations will be on a grid pattern. A probe type drill rig would be used to obtain soil samples from a depth below the site surface of 5 feet. Each soil sample would be retrieved within a new core barrel for recovery and testing. All drilling and sampling equipment will be properly decontaminated prior to each new test location. Alternately, an auger type drilling rig could also be used to obtain quarterly soil samples. Each soil sample would be obtained using laboratory chain-of-custody documentation. All samples will be submitted to Technology Laboratory located in Fort Collins, Colorado. Soil samples will be tested for TP14 using US EPA Method #418.1. Soil samples will also be analyzed for BTEX compel rods via US EPA Method #8015 Modified. • • • • Results of soil testing will be reported to the OGCC and WCDPHE each quarter. Quarterly reports will include all laboratory data as well as test boring location maps and other appropriate figures or diagrams. A release exceeding soil quality standards will immediately be reported to the OGCC and WCDPH!i. ANNUAL SOIL TESTING Annual roil sampling will also be performed. During the annual testing, an auger type drill rig, such as a CME 75 drill rig, would be used to advance test borings. Soil samples would be obtained from a minimum of ten test locations. Soil samples will be obtained from five, ten. fifteen at:d twenty Hot depth intervals. At least fen test soil borings will be drilled and tested each year of operation. The locations of test borings will be within the active stockpiled soil areas. Testing of soil will be performed using a grid pattern. Petroleum soil stockpiles will first be removed from selected test areas to permit access to the areas by a drilling rig. Stockpiled soil will be removed to restore the test locations to near original grades. This will permit sampling of underlying native soil to access whether a release to underlying soil has occurred from soil being treated. Soil core samples will be obtained from the test locations using a 5 foot continuous split-barrel core sampler. All drill tools and sample barrel samplers will be decontaminated prior to each use or new boring. Each boring will be logged by a Professional Geologist. Head space testing of recovered soil core; will be performed in the field using a calibrated Photoionizalion Detector. A soil boring log will be prepared for each annual test boring. The locations of test borings will also be indicated on maps prepared for each annual testing event. SOIL RELEASE ASSESSMENT AND CORRECTIVE ACTION PLAN In addition to quanerly reports, an annual soil testing report will also be submitted to the OGCC and WC )PI IE. If a release of BTEX or TPH compounds is documented at a depth greater than 5 feet below the suri!ce of the site, a plan to further assess the release to soil would be immediately prepared and submitted. The plan may require the installation of additional test soil borings to define the source area of the released hydrocarbons. The operator may be required to suspend acceptin petroleum soil from exploration and production operations for treatment until an assessment is completed and reported. Once the source and extent of a petroleum release is documented, a plan to remediate the release will also he developed and submitted for approval. The plan may stipulate soil removal, in-situ soil treatment or some other method of remediating soil which is impacted above permissible limits W:h BTEX :md/or TPI-I compounds. • • REMEDIATION PROGRESS SAMPLING During the treatment of petroleum contaminated soil in the landfarm area, periodic sampling may be conducted. Representative soil samples will be analyzed for BTEX and TPH compounds to document biodegradation progress of soil being treated. More aggressive treatment may be recommended for portions of the landfarm which contain heavier hydrocarbons, which do not generally degrade as quickly as lighter hydrocarbon wastes. Field screening via the head space test method may also be employed to document bioremediation progress of soil undergoing treatment at the landfarm. CHARACTERIZING INCOMING WASTE SOIL The landfarm may accept maximum volumes of petroleum contaminated soil based upon the concentrations of TPH compounds in different waste streams. It is recommended that TPH laboratory analyses of waste soil be performed to document the concentrations of petroleum soil delivered for treatment at the facility. Sampling and testing of incoming soil will be performed to document soil contaminants generated at different site locations. Records of test data will be maintained for a period of at least three years. CHARACTERIZING INCOMING FRAC SAND WASTE Occasionally, the facility may accept frac sand waste generated from well stimulation treatments. Approximately 300 to 500 cubic yards may be deposited at the landfarm annually. The frac sand waste will be tested for certain parameters listed in Table 910-I taken from guidelines of the Water Quality Control Commission. The maximum permissible concentrations of TPH compounds at the site shall not exceed 50,000 mg/Kg (ppm), as documented by testing. TESTING OF SOIL TO BE RECYCLED Before the operator may recycle treated soil from the facility, field screening will be performed using a calibrated Photoionization Detector. Head space surveys will be conducted to determine which landfarm soil may be treated to standards. Additionally, samples of treated soil may be obtained. The treated waste soil samples will be analyzed for BTEX and TPH compounds using the prescribed EPA preparation and test methods. Sample locations will be identified on prepared maps. Soil must he treated to within applicable standards for the location which receives the remediated soil. Waste testing results will be reported, as requested, to the OGCC and WCDPIIE. The operator will maintain a log of soil, with waste manifests, received at the facility. The generation location of soil, approximate volumes and initial analytical test results will be recorded. Waste soil testing results will be maintained in the Denver office. Waste manifests will be maintained at the LaSalle office. The location receiving remediatcd soil should also he recorded and documented, as requested. • • Upon approval of the proposed plans, Petro-Canada Resources, Inc. will schedule the quarterly soil testing at the facility. Please contact us with any questions which you may have. Sincerely. / Mark H.

The submittal was intended to address Conditions of Approval 1.A., D., E., F., G., H., I., and K of USR#1517. It appears that your letter adequately addresses Condtions 1.D., F., H., and I. However, as we discussed, additional information is necessary to address the other conditions. I'll summarize our comments below: 1) The soils monitoring plan needs more detail and should reflect the requirements outlined in development standard #12. Any plan should describe the method of obtaining samples and the method of analysis. 2) The groundwater monitoring plan needs more detail and should reflect the requirements outlined in development standard#11. Any plan should describe the method of obtaining samples and the method of analysis. Here a few of the items that requirement more detail and/or information: a) The information you submitted indicates that you'll follow COGCC std's to measure groundwater impact. Development standard #11 requires certain measures be taken should there be any "statistical increase over background". b) Your letter is proposing a different sampling scheduled than outlined in development standard #11. The County will consider modifying the frequency at some future date but it is inappropriate to request the modification at this point. Any future request must be accompanied with justification for the modification and a description of the hydraulic conductivity of the aquifer. c) The plan should include permits from the Colo Div of Water Resources that the wells are appropriately permitted as MWs. d) The plan should include diagrams of the wells that include not only the lithology but all the completion information concerning the well, ie. screened interval, sand/gravel pack, plug, etc. e) Please identify if wells are appropriately labeled in the field. f) You have provided us a map that indicates there are 6 monitoring wells on the property. You have provided boring logs for 5 holes that we're dug. We also understand that there is no completion information for MW6. However, it is not clear which boring correlates to each monitoring well, ie. was SB-1 was completed as MW-1, etc. 3) There are several references to a "three-ft. high earthen berm" that will surround the site and its ability to control run-on and run-off. Please provide documentation that any berm constructed around the site will prevent run-on and contain the run-off from a 100-year, 24-hour precipitation event. This is typically conducted by an engineer. Please provide the additional information at your earliest convenience. Don't hesitate to call me should you have any questions, etc. Trevor Jiricek, M.A. Director, Environmental Health Services Weld County Department of Public Health & Environment 1555 N. 17th Ave Greeley, Colorado 80631 970-304-6415, ext. 2214 (office) 970-304-6411 (fax) 02/27/2006 It County Planning Department • !nil SUITEWE:T ,UILDIt1G JAN 3 0 2006 pereo•rattaur►, Petro-Canada Resources(USA) Inc.

Dear Sir or Madam: Petro-Canada Resources (USA) Inc (Petro-Canada), is submitting an APEN for the Centralized Land Treatment Facility located in the NENWNW of Section 18, T4N, R64W of Weld County. This facility is permitted with Weld County and with the Colorado Oil & Gas Conservation Commission. The facility is permitted to process 20,000 cubic yards of soil per year and is required to treat the soil to 1,000 ppm or less of total petroleum hydrocarbons (TPH). As such the VOC emissions for this submittal were calculated by subtracting 1,000 ppm TPH from the actual ppm of the soil. It was also assumed that 100% of the TPH is volatile organic carbons. Additionally emissions were calculated based 40% of the TPH volatilizing and the remaining 60% biodegrading. Based on research studies of land treatment facilities 13% to 66% of the volatiles will be emitted to the atmosphere in typical land treatment facilities. A report titled Assessment of Air Emissions From a Laboratory Land Treatment Facility, documented 13% to 40% volatile organic emissions to the atmosphere based on six tests. Therefore for the purposes of this submittal the median of 40% volatilization was used in the emission calculations. The first year of operation will have a soil throughput of approximately 20,000 cubic yards. This is due to two large clean-up activities. The soil throughput of the facility for the remaining years of operation is expected to be approximately 1,000 cubic yards. It was estimated that 15% of the soil has a TPH concentration of 6,000 ppm and that the remaining 85% of the soil has a concentration of 1,200 ppm. As such the estimated VOC emissions from the first year of operation are 4.5 TPY and for every year after that they are 0.2 TPY. Emission calculations are enclosed. 1099 18th Street,Suite 400 Denver,CO 80202 Phone: 3030-297-2100 Fax: 303-297-7708 • • Petro-Canada(USA)Resources,Inc.

Use by Special Review Permit #1517 Mineral Resource Development Facility p OCANADA Centralized Land Treatment Facility Soil and Ground Water Monitoring Plan Soil Monitoring Representative soil samples will be collected from each volume taken to the Landfarm for recycling. The soil samples will be analyzed using either a combination of US EPA Method 8015 Modified-gasoline and—diesel range TPH or Total Recoverable Petroleum Hydrocarbons (TRPH) using US EPA Method 418.1. During the land treatment process,performance monitoring will be employed using a photoionization monitor(PID) and field headspace testing of volatile organic compounds present in the thin spread soil. Land treatment will be considered complete when field headspace measurements are below 250 ppm. Alternatively, confirmation lab samples may be collected for laboratory analysis of TPH/TRPH and,when this method is employed, land treatment will be deemed complete when TPH/TRPH concentrations are determined to be below applicable Colorado Oil and Gas Conservation Commission (COGCC) allowable concentration levels for the area in which the treated soil will be re-used. Ground Water Monitoring Four ground water monitoring wells have been installed at the facility, including one upgradient well and three wells located along the downgradient western margin of the facility. Ground water elevations have been measured and the direction and gradient of ground water flow has been established. Ground water levels will be measured and ground water samples collected for laboratory analysis according to the schedule outlined below. Ground water samples will be submitted under chain of custody to the laboratory for analysis of benzene, toluene, ethylbenzene, and total xylenes (BTEX) compounds using US EPA Method 8020. Monitoring Schedule: • Quarterly: Ground water levels will be measured and ground water samples collected for laboratory analysis on a quarterly basis for the first four quarters of Landfarm operations. • Semi-Annual: Ground water monitoring and sampling will switch to a semi- annual basis following the collection of four consecutive quarterly ground water samples that exhibit BTEX concentrations below COGCC allowable contaminant concentration levels contained in Table 910-1. • Annually: Ground water monitoring and sampling will switch to an annual basis following the collection of two consecutive semi-annual ground water samples that exhibit BTEX concentrations below COGCC allowable contaminant concentration levels.

PrIM Use by Special Review Permit #1517 Mineral Resource Development Facility PE1RO DA Centralized Land Treatment Facility DESIGN AND OPERATIONS PLAN Legal Description of the Site NENWNW Section 18, Township 4 North, Range 64 West Approximately three miles east of LaSalle, Weld County, Colorado Topography, Geology and Hydrology The centralized land treatment facility(the Landfarm) is located on approximately 20 acres of fallow agricultural land approximately three miles east of LaSalle in southern Weld County, Colorado. The land surface occupies an elevation of 4950 to 4980 feet(ft) above sea level and slopes slightly to the west and southwest. Soil underlying the site comprises the Vona sandy loam. Meridian Environmental completed a soil test boring at the site to describe subsurface geological and hydrogeological features. The boring encountered unconsolidated, dry, well sorted very fine- to fine-grained sand extending from the ground surface to a depth of 10 ft. Soft to moderately hard, dry to moist sandy clay and clay underlie the sand from a depth of approximately 10 ft. to 20 ft. below the ground surface. Beneath the clay is a two-ft. thick sandy gravel layer that is saturated with ground water. Based on maps maintained by the Weld County Planning Department, the site does not occur within a geologic hazard area or floodplain. As mentioned above, ground water occurs in a confined gravel layer at a depth of approximately 20 ft. below the ground surface. The overly 10 ft. thick clay layer forms an aquiclude of low permeability material that effectively limits downward migration of water. The local ground water drainage divide is probably located 750 ft. to the east of the site and, based on topography, ground water probably flows to the west and southwest. Surface water features in the immediate vicinity of the site are limited to an unmapped irrigation ditch located 1,000 ft. to the west. The ditch runs generally south to north and flows to the north. There are no mapped surface water features or wetlands in the immediate area. The average annual precipitation rate is 12.27-in. and evaporation rates exceed an average of four-in. per month. • • Pr! Petro-Canada Resources (USA) Inc. Use by Special Review Permit #1517 Mineral Resource Development Facility PETROCANAQA Centralized Land Treatment Facility Centralized Facility Siting Requirements • Site Plan: Please see the Plat included in the Weld County USR application. • Measures to Limit Access: A six-ft. chain link fence with a locked gate to limit access will be erected around the perimeter of the Landfarm. • Fire Lane: A fire lane and buffer zone will be maintained within the perimeter fence surrounding the land treatment area, in accordance with Rule 908.b.D. • Surface Water Diversion: A minimum three-ft. high earthen berm will be erected around the active land treatment area to prevent surface water run-on and runoff. The berm will be sufficient to accommodate a 100-year 24-hour precipitation event. Waste Profile The Petro-Canada Landfarm will accept only hydrocarbon-affected soil and frac sand derived from Petro-Canada operated wells and production facilities for land treatment and recycling. Petro-Canada will submit a representative waste profile for hydrocarbon-affected frac sand prior to land treating frac sand at the Landfarm. Petro-Canada anticipates treating 300 to 500 cubic yards of hydrocarbon-affected soil and a similar volume of frac sand on an annual basis. Facility Design The Landfarm is an inherently simple design, consisting of a 20 acre fenced plot. The land treatment process consists of thin-spreading the soil on the ground surface to a depth not to exceed 2-ft. The thin spread soil will then be tilled,with moisture and nutrients added as needed, to promote natural biodegradation of hydrocarbons. After hydrocarbon concentrations within the thin spread soil are reduced to applicable COGCC allowable contaminant concentration levels contained in Table 910-1, the soil will be collected into piles and stockpiled for eventual use as backfill and construction material at other Petro-Canada facilities. The land treatment area will be surrounded by an earthen berm and six-ft. chain link fence to prevent run-on and runoff from contacting the thin spread and to limit access. • • Petro-Canada Resources (USA) Inc. Use by Special Review Permit #1517 Mineral Resource Development Facility PETROCANADA Centralized Land Treatment Facility Operating Plan • Treatment Method: Hydrocarbon-affected soil will be thin spread directly on the ground surface to a thickness not to exceed two-ft. The thin spread soil will be tilled and moisture added periodically to augment natural biodegradation of hydrocarbons. Nutrients in the form of commercial fertilizer may be added to further augment the natural biodegradation process. • Loading Rates: The site will be operated as a soil recycling facility, and individual soil lifts will be segregated and fully treated and removed prior to adding subsequent additional soil lifts for treatment. Contaminant loading will be limited using this approach, and the maximum hydrocarbon concentration in soil to be treated at the site will not exceed 50,000 parts per milling Total Petroleum Hydrocarbons (TPH). Liquid waste will not be treated at the facility. The limited mixing of thin spread hydrocarbon-affected soil and underlying clean soil will limit hydrocarbon impacts to underlying soil. • Nutrients & Soil Amendments: Natural biodegradation using in-situ hydrocarbon degrading bacteria is the proposed method of treatment. Soil amendments will be limited to tilling to oxygenate the soil, adding water periodically to maintain soil moisture, and possibly adding commercial fertilizer in the form of lawn food to provide additional nutrients, if needed. • Dust& Moisture Control: Dust will be suppressed as needed using a commercial water truck equipped with a spreader boom. Moisture control will not likely be necessary,but runoff and run-on will be controlled by surrounding the land treatment area with an earthen three-ft. high berm. • Sampling: Representative soil samples will be collected from each volume of soil taken to the Landfarm for recycling. The soil samples will be analyzed using either a combination of US EPA Method 8015 Modified-gasoline and—diesel range TPH or Total Recoverable Petroleum Hydrocarbons (TRPH) using USA EPA Method 418.1. • 0 Petro-Canada Resources (USA) Inc. Pr! Use by Special Review Permit #1517 Mineral Resource Development Facility PETROtANADA Centralized Land Treatment Facility During the land treatment process, performance monitoring will be employed using a photoionization monitor(PID) and field headspace testing of volatile organic compounds present in the thin spread soil. Land treatment will be considered complete when field headspace measurements are below 250 ppm. Alternatively, confirmation lab samples may be collected for laboratory analysis of TPH/TRPH and,when this method is employed, land treatment will be deemed complete when TPH/TRPH concentrations are determined to be below applicable COGCC allowable concentration levels for the area in which the soil will be re-used. • Inspection & Maintenance: The land treatment facility will be inspected at least weekly by Petro-Canada personnel. The inspection will include a visual check of all thin spread and stockpiled materials, the condition of secondary containment berm, the condition of the perimeter fence. The berm and fence will be maintained as needed. • Emergency Response: A sign will be posted at the entrance to the land treatment facility listing Petro-Canada's 24-hour contact phone number, to be used in the event of an after ours emergency at the facility. Emergencies occurring during normal business hours will elicit a response from the adjoining Petro-Canada field office. In addition. The Landfarm will be integrated into Petro-Canada's Emergency Response and Reporting Plan addressing emergency response and call-out procedures for all the Company's Colorado facilities. • Recordkeeping: Petro-Canada will maintain for a minimum three year period records of the sources, volumes, initial contaminant concentrations, final contaminant concentrations, and final disposition of all waste treated at the facility, as well as inspection and ground water monitoring records. • • Site Security: The land treatment area will be surrounded by a six-ft. chain link fence with a locked gate. Access will be limited to Petro-Canada personnel and contractors under the direct supervision of Petro-Canada personnel. • • Pr! Petro-Canada Resources (USA) Inc. Use by Special Review Permit #1517 Mineral Resource Development Facility PETROCANADiA Centralized Land Treatment Facility • Hours of Operation: The Landfarm will be operated from 7:00 AM to 5:00 PM, Monday through Friday. Access to the Landfarm during weekends and after normal business hours will be limited to emergency situations only. • Final Disposition of Waste: The land treated soil/frac sand will be recycled for use as backfill and building material at Petro-Canada facilities. The material may be used to build access roads, well pads, secondary containment berms, and production facilities. Before re-use, residual hydrocarbon concentrations will be confirmed to be below COGCC allowable contaminant concentration levels using a combination of field PID and laboratory analytical methods described above. In addition, the Weld County public works department has inquired with Petro-Canada about potentially utilizing recycled soil for road construction projects. Such beneficial re-use will only be attempted with prior approval of COGCC and the Weld County Department of Public Health and Environment. Petro-Canada reserves the right to disk some remaining treated soil/frac sand into the underlying soil at the time of facility abandonment. In this event, TPH/TRPH concentrations in the mixing zone will not exceed COGCC allowable contaminant concentration levels. PIM PETROCANADA CLOSURE PLAN Petro-Canada Resources (USA) Inc.

(Western) has completed a limited Phase II Environmental Assessment of an active soil treatment area. The facility receives petroleum soil for remediation and subsequent recycling. The facility has received petroleum waste soil from operating well locations, tank batteries and other locations. Petro-Canada has recently acquired the soil treatment facility and operating leases from another operator. SCOPE OF WORK Western was to conduct a limited environmental assessment of the landfarnt area. Western was to drill test soil borings at approved locations adjacent to the soil stockpile areas. Locations for test borings were located upgradient and downgradient of current petroleum soil accumulations. Subsurface soil samples were to be logged, field tested and submitted for laboratory testing to a certified analytical laboratory. In addition to soil testing, permanent ground water monitoring wells were to be installed in the test soil borings. Ground water samples were to be obtained and tested for contaminants of concern. Soil and ground water samples were to be tested for the presence of certain hydrocarbons. DRILLING SOIL TEST BORINGS Drilling was performed by Western Cleanup Corporation of Fort Morgan, Colorado. A CME Model 75 hollow stern truck mounted drill rig was used to drill the test soil borings. OSHA certified personnel performed all drilling and well completion tasks. A drill stem consisting of 6 3/4 inch hollow stem augers was used with a cutter head bit. Soil intervals were recovered from the test borings using an internal 5 foot continuous core split barrel sampler. Drill tools, instruments and sampling equipment were decontaminated before each use. Recovered soil core intervals were described by a Professional Geologist. MONITOR WELL INSTALLATION AND SAMPLING After encountering bedrock refusal when advancing test soil borings, monitor wells were installed. The wells were completed to depth with 0.010" cut slot well screens. A PVC point cap was placed below the screened intervals. Wells were screened with 10 feet of PVC well screen from total depth to 10 feet above total depth. A 2" PVC riser pipe extended past the top of the wells. A washed 10/20 quartz silica sand and bentonite were also placed at proper intervals to complete the new wells. All new wells were completed as stick-up wells, in accordance with customer requests. The well stick-ups are comprised of 4" steel casings with locking covers. After completing five new monitor wells, the elevation surveys were completed. There was an existing well (MW6) which already was present downgradient of the soil pad. No borehole logs or completion diagrams were available for the MW6 well. DEVELOPMENT OF WELLS, SURVEYS AND GROUND WATER TESTING Western personnel obtained ground water level measurements using a decontaminated electronic water level. Wells were developed using new disposable well bailers. Water was not found to be present in the MW2, MW3 or MW5 wells. These locations are devoid of a measurable ground water column from the surface of the site to the underlying hard bedrock layer. A YSI Model 550A instrument was also used to determine dissolved Oxygen levels and ground water temperatures of wells containing water. Water and sediment was removed from the sampled wells until a representative ground water sample could be obtained. GROUND WATER TEST RESULTS As with the soil samples, all ground water samples were obtained using laboratory chain-of- custody documentation. All ground water samples were analyzed by Technology Laboratory of Fort Collins, Colorado. Water samples were tested using EPA laboratory methods. All water samples were tested for BTEX and TRPI 1-GRO compounds. No BTEX or TRPI-I-GRO compounds were detected in any submitted ground water samples. The water that does underlie some areas adjacent to the stockpiles of oily soil has not been impacted by migrations of petroleum compounds from the treatment areas. RESULTS AND CONCLUSIONS Drilling and acquisition of soil cores indicates that areas adjacent to stockpiled soil are within state quality standards. Unconsolidated vadose zone soil consists of tight silts, !:ands and weathered shale. A competent bedrock shale layer exists below surface sediments at depths from 13 feet to 32 feet below the site surface. • Field screening of recovered soil cores was performed using a calibrated Photoionization detector instrument. Soil samples were obtained for testing using laboratory chain-of-custody documentation. Soil intervals were acquired from several soil types and from varying depths below the site surface. SOIL TEST RESULTS A total of 14 subsurface soil samples were obtained from cored intervals in the test borings. The samples were submitted to Technology Laboratory, Inc. located in Fort Collins, Colorado. EPA test methods were employed to prepare and analyze the soil samples. All soil samples were analyzed for BTEX and TRPH - GRO compounds. A map indicating boring and well locations is also included as a report attachment. Results of soil analyses are presented in attached analytical summary tables. Testing of soil samples upgradient and downgradient of the stockpiles of soil did not detect any chemicals of concern in concentrations exceeding Colorado Oil & Gas Conservation Commission soil quality standards. It appears that subsurface soil in the test locations has not been significantly impacted by site operations. No BTEX compounds were documented in any of the 14 soil samples tested. A small trace of TPl-I compounds was detected, but concentrations are well below state quality standards. SOIL TYPES AND HYDROGEOLOY There were several types of unconsolidated and bedrock lithologies present in the five test soil borings. Although soil core recoveries were good, extremely difficult auger drilling was encountered near the bedrock interface. Surface soil consists mostly of sand and silt. Soil boring logs for the test borings are included as attachments to this report. A weathered limonite stained soil zone is present directly over competent bedrock. The soil layers above the bedrock appeared dry when cored. There was no visible ground water present except in monitor well MW4. Some of the borings completed as monitoring wells did not contain ground water when surveyed. To determine the site ground water elevations and flow directions, a water elevation survey was performed prior to purging and sampling the installed wells. A site survey was also conducted to determine reference elevations of certain points on installed wells. A professional land surveyor completed the surveys. USGS elevation datum was used to construct a ground water elevation contour map for the site. Ground water flows to the west from the landfarm area. It should be noted that only half of the wells contained enough ground water to sample and measure. Consequently, the predicted top of the underlying aquifer had to be inferred from existing data. Ground water flows to the west of the soil treatment pad lacil ty. Ground water has tested to be within basic standards for ground water quality in accordane with the Colorado Water Quality Control Commission guidelines.
