Buffalo Head Projects: 12633.01

1 INTRODUCTION In response to a well head failure which resulted in the release of a mixture of oilfield waste water and production fluid from the Gibson Energy Partnership (Gibson) Oungre 8-16-2-14 W2M (8-16) salt water disposal (SWD) site, Gibsons contracted Buffalo Head Environmental Ltd. (Buffalo Head) to assess the release and direct remedial work required. This report outlines the initial release response and remediation work completed.

1.1 Background and Scope of Work On October 5, 2014, a leak occurred when a section of the 8-16 SWD well head corroded allowing a mixture of oilfield waste water and production fluid to be released. The fluid, which originated from the Gibson 1-16-2-14 W2M (1-16) waste processing facility (WPF), pooled within the disposal building before running out onto the gravelled access road. Fluid was temporarily retained by clay berms surrounding the well site but eventually was able to migrate north away from the well site and east out into an area of agricultural land. Fluid then ran approximately 95 meters east across the agricultural land before reaching the ditch bordering the west edge of Highway 35 (Figure 1). The leak was discovered by Gibson personnel a few hours after it had occurred and a vacuum truck was retained immediately to recover standing fluid from the surface of the spill area.

Gibson personnel contacted Buffalo Head on the afternoon of October 5, 2014, to respond to the release and implement containment, recovery and remediation activities and ensure final remediation efforts met with the expectations of the Saskatchewan Ministry of the Economy, Petroleum Development Branch (ECON, PDB) and Gibson. From October 6 through October 8, 2014, Buffalo Head directed remedial efforts including a remedial excavation of impacted soils as well as collection of confirmatory soil samples. Fluid recovery during the initial response as well as reclamation of the remedial excavation was completed in-house by Gibson personnel.

2 SITE DESCRIPTION The 8-16 SWD is located 2.4 kilometres (km) south and 0.25 km west of Oungre, SK, within the Rural Municipality of Souris Valley, number 7, on agriculturally zoned lands currently used for agricultural cropping. As referenced in the Acton et al. (1995), The Ecoregions of Saskatchewan, the 8-16 SWD is located in the Lake Alma Upland within the Mixed Grassland Ecoregion of the Prairie Ecozone of Saskatchewan. The Lake Alma Upland is a hilly hummocky morainal area, representing the Missouri Coteau. It extends from Ceylon to the United States border. There is some drainage to Long Creek in The Gap and from several coulees along the escarpment; otherwise, surface drainage is limited to flow to local small lakes. Native mixed-grass prairie is limited to hummocky morainal landscapes, where it is interspersed with cropland. A more continuous grassland cover occurs in steeply sloping areas and coulees on the Missouri Coteau escarpment. A variety of grasses are common on the uplands, with shrubs limited to more moist depressional areas. Dark brown loam soils formed in glacial till deposits are common on all of these landscapes. Most of the Lake Alma upland is cropland. Cereals are the major crop. Pasture and rangelands are associated with local areas of hilly land.

The regional soils information for the project area was referenced from the Weyburn and Saskatchewan Portion of the Virden Map Area. The spill area spans two separate local soil descriptions, Am2 and AmBk1. Amulet (Am) soils are dominantly dark brown soils formed in clay loam textured moderately calcareous glacial till. Brooking (Bk) soils are dominantly dark brown solonetzic soils formed in loam to clay loam textured, moderately calcareous glacial till. Am2 soils are mainly orthic Amulet soils with eroded and calcareous Amulet soils on knolls, and poorly drained soils in depressions. AmBk1 soils are mainly orthic Amulet soils with calcareous Amulet soils on knolls, and solonetzic Brooking soils in lower areas. Strong solonetzic soils are not common. The project area also spans two distinct soil salinity designations, 1MP and 2MP as derived from the Soil Salinity Map of the Weyburn-Virden Area, Saskatchewan. The 1MP designation is defined as soil where a few salt crystals are usually visible and under native conditions salt tolerant plants are present; 0-3% of the area is affected by salinity; average electrical conductivity (EC) of the 0-60 cm depth is 4-8 deciSiemmens per metre (dS/m); Saline soils occur on the edges of depression, sloughs or runways. All soils in the bottoms of the depressions are leached and non-saline. These areas generally occur on relatively level or very gentle regional slopes. The 2MP designation is defined as soil where a few salt crystals are usually visible and under native conditions salt tolerant plants are present; 3-10% of the area is affected by salinity; average EC of the 0-60 cm depth is 4-8 dS/m; Saline soils occur on the edges of depression, sloughs or runways. All soils in the bottoms of the depressions are leached and non-saline. These areas generally occur on relatively level or very gentle regional slopes.

3 METHODOLOGY

3.1 Initial Spill Response and Remediation Gibson personnel shut in the 1-16 WPF, which feeds the 8-16 SWD, upon discovery of the leak on October 5, 2014, and contracted Brady Oilfield Services (Brady) of Halbrite, SK, to supply a vacuum truck to recover standing fluid from the surface of the spill area. A total of 3.0 cubic meters (m3) of fluid was recovered as part of the initial response and transported to the Gibson Midale WPF near Midale, SK, for disposal. Gibson personnel then initiated emergency response by completing notifications to Buffalo Head and the Saskatchewan Ministry of the Economy, Petroleum Development Branch in Estevan, SK.

Buffalo Head responded to the release on October 6, 2014. Upon inspection it was determined the release had occurred due to a corroded section of the well head which allowed an unknown volume of oilfield waste water and production fluid to be released from the well head. Fluid pooled within the disposal building before running out onto the gravelled access road (Photos 1 & 2). Fluid was temporarily retained by clay berms surrounding the well site but eventually was able to flow north away from the well site and east out into an area of agricultural land (Photos 3-5). Fluid then migrated approximately 95 meters east across the agricultural land before reaching the ditch bordering the west edge of Highway 35 (Figure 1).

Preliminary field screening was completed using an EC soil probe with conductivities regularly exceeding field screen detection limits of 20 dS/m through the centerline of the spill; background conductivities varied between 1.6 and 2.2 dS/m. A water sample was taken from a small volume of fluid (<1 litre) which had collected in a low depressional pocket in the west ditch bordering Highway 35. The sample was field screened for EC and chloride concentration with results exceeding detection Limits of 20 dS/m and 6,627 mg/L respectively. An emergency request was placed with Sask1stCall and Quest Line Locating (Quest) of Estevan, SK, was contracted to locate any buried facilities and to perform a three way sweep of the spill area in preparation for remedial excavation. A flowline and power cable running

from the 1-16 WPF to the 8-16 SWD as well as a cathodic system was located and staked in addition to a Saskpower cable running north-south through the spill area east of the 8-16 SWD. Tristen Hydrovac (Tristen), of Regina, SK, was retained to complete daylighting of the power cables, flowline and cathodic lines within the proposed remedial excavation area (Photo 6).

On October 7, 2014, Buffalo Head arranged to have Torrent Energy Services (Torrent) of Weyburn, SK, supply a trackhoe and end dump trucks to excavate impacted soil from the spill area and haul to the Gibson Heward Landfill, near Heward, SK, for disposal (Photos 7-10). An EC soil probe was used to field screen and guide the excavation. A total of 198.9 metric tonnes of soil was loaded and hauled to the treatment pad at the Gibson Heward Landfill.

On October 8, 2014, Buffalo Head arranged to have Torrent supply a trackhoe and end dump trucks to recover any remaining impacted soil and haul to the Gibson Heward landfill for disposal (Photos 11-14). An additional 144.2 metric tonnes was recovered for a total of 343.1 metric tonnes hauled to date. The excavation area was measured using differentially corrected GPS and revealed a total surface area of 1,159 m2. The area in the vicinity of the well head which was not scraped measured approximately 50 m2. Residual field measured conductivities ranged from 1.5 to 3.4 dS/m across the remedial excavation. Following impacted soil removal, Buffalo Head recovered soil samples from the spill area which were then relinquished to AGAT Laboratories (AGAT), in Calgary, AB, for analysis.

On October 23, 2014, Gibson personnel completed reclamation of the remedial excavation which, as reported by Gibson, required the importing and placement of approximately 40 m3 of clay and 230 m3 of topsoil. Following the placement of the material using a rubber-tired backhoe, a grader was retained to re-contour the surface of the reclamation area (Photos 15 & 16).

Initial Response and Remediation Summary On October 5, 2014, Gibson personnel identified a leak from the 8-16 SWD well. An unknown volume of fluid was released and pooled within the disposal building before running out onto the gravelled access road. Fluid was temporarily retained by clay berms surrounding the well site but eventually was able to flow north away from the well site and east out into an area of agricultural land. Fluid then migrated approximately 95 meters east across the agricultural land before reaching the ditch bordering the west edge of Highway 35. During the initial response a total of 3.0 m3 of fluid was recovered and disposed of at the Gibson Midale WPF. Buffalo Head directed an assessment and remedial excavation at the site from October 6 through October 8, 2014. Throughout the course of the remedial activities, a total of 343.1 metric tonnes of impacted soil was excavated from the release area and disposed of at the Gibson Heward Landfill. The excavation area was measured using differentially corrected GPS and revealed a total surface area of 1,159 m2. The area in the vicinity of the well head which was not scraped measured approximately 50 m2. Following the remedial excavation confirmatory soil sampling was completed by Buffalo Head. On October 23, 2014, Gibson personnel directed reclamation of the remedial excavation including importing and placing approximately 40 m3 of clay and 230 m3 of topsoil.

3.2 Ground Disturbance All ground disturbance procedures were conducted in accordance with Gibson and Buffalo Head protocol. The ground disturbance package is attached in Appendix 1.

On October 6, 2014, Buffalo Head placed an emergency request with Sask1stCall to have all subscribing companies, with underground facilities in the SE ¼ 16-002-14 W2M, locate and mark any facilities in proximity to the proposed remedial excavation at the release site (ticket number 2014410331). Saskatchewan Power Corporation (SaskPower), Saskenergy Corporation (SaskEnergy) and Saskatchewan

Page 3 of 7

Telecommunications Holding Corporation (SaskTel) were notified as part of the Sask1stCall request. Magna Electric Corporation (MEC) of Regina, SK, completed the underground line locate request for SaskPower, SaskEnergy and SaskTel the same day with only a buried SaskPower cable and overhead SaskPower lines present in the vicinity of the proposed remedial excavation. Quest completed a third party electronic sweep for underground facilities with a flowline and power cable running from the 1-16 WPF to the 8-16 SWD as well as a cathodic system located and staked in addition to the SaskPower cable located by MEC. Tristen completed daylighting of the power cables, flowline and cathodic lines within the proposed excavation area. All buried facilities were located and found to be deeper than 1.0 meters below grade.

3.3 Sampling Locations Throughout the remedial excavation soil samples were acquired from twenty-three (23) locations (SP101-SP123). Of those acquired, seven (7) samples (SP101, SP103, SP106, SP109, SP113, SP119 and SP123) and two (2) control samples taken from background locations within the agricultural land (SC101) and from the highway ditch (SC102) were relinquished to AGAT for analytical analysis. All samples were retained in laboratory supplied containers.

3.4 Analytical schedule All soil samples, SC101, SC102, SP101, SP103, SP106, SP109, SP113, SP119 and SP123 were analyzed for detailed salinity. A copy of the laboratory report (14S899843) is attached in Appendix 2.

3.5 Assessment guidelines Tabulated soil analytical results were compared to the following criteria:  Saskatchewan Petroleum Industry/Government Environment Committee (SPIGEC) Saskatchewan Upstream Petroleum Sites Remediation, Guideline Number 4 (Update November 2009).

Due to the presence of agricultural lands in the vicinity of the site the criteria for agricultural soil was referenced. For the purpose of the soil salinity assessment, pH, EC and sodium adsorption ratio (SAR) were compared to the SPIGEC Agricultural Land Use criteria.

For agricultural soil analysis the soil salinity guideline criteria are divided into soil quality categories related to crop growth including “unconditional use”, “moderately tolerant crops” and “tolerant crops” for EC and “unconditional use” and “conditional use” for SAR. Soils classed as “unconditional use” require no crop monitoring. Soils classed as “moderately tolerant crops” and/or “conditional use” for EC and SAR respectively, require a minimum of three years crop growth and yield monitoring. A soil classed as “tolerant crop” for EC requires a minimum of five years crop growth and yield monitoring.

4 RESULTS

4.1 Field Observations On October 6, 2014, preliminary field screening was completed using an EC soil probe. Conductivities exceeded field screen detection limits of 20 dS/m in the centerline of the spill and reduced to 4-5 dS/m near the edges of the spill area. Background conductivities varied between 1.6 and 2.2 dS/m. A water sample was collected from a small volume of fluid (<1 litre) which had collected in a low depression in the west ditch bordering Highway 35. The sample was field screened for EC and chloride concentration with results exceeding detection criteria of 20 dS/m and 6,627 mg/L respectively.

Page 4 of 7

Field screening was also completed throughout the remedial excavation with EC levels of less than 3.5 dS/m typically left in place pending laboratory results. Field screen results are noted along with sample locations in Figure 1.

4.2 Analytical Data Salinity Parameters Control – SC101 was acquired from an area of agricultural land east of the 8-16 SWD and SC102 was acquired from the west ditch bordering Highway 35. Each sample was acquired at depths of 0-15 cm with each sample falling within SPIGEC unconditional use criteria for pH, EC and SAR.

Spill Area – SP101 was acquired from the un-scraped area around the well head and revealed EC and SAR levels which exceed SPIGEC tolerant crop use and conditional use criteria respectively. A chloride concentration of 1,830 mg/kg revealed produced water impact remaining in the vicinity of the well head. SP103 was acquired from the clay pad surrounding the 8-16 SWD and revealed an EC level slightly above moderately tolerant crop use criteria and an SAR level within conditional use criteria. A chloride concentration of 466 mg/kg indicates some residual produced water impact in the vicinity of the sample point in addition to evidence of naturally occurring salinity due to an elevated sulfate concentration of 1,150 mg/kg. SP106, SP109 and SP113 were acquired from the agricultural crop area east of the 8-16 SWD and revealed EC levels within moderately tolerant crop use criteria and SAR levels within unconditional crop use criteria. Chloride concentrations of less than or equal to 50 mg/kg versus elevated sulphate concentrations of 1,240 - 2,090 mg/kg suggests that increased EC levels are influenced primarily by naturally occurring salinity. SP119 and SP123 were acquired from the remedial excavation in the highway ditch. Each sample revealed EC and SAR levels within SPIGEC unconditional land use criteria. All soil samples acquired also fell within SPIGEC agricultural land use criteria for pH.

Results of the laboratory analysis of the soil salinity parameters are summarized in Table 1 below.

4.3 Conclusion On October 5, 2014, a leak occurred when a section of the 8-16 SWD well head corroded releasing a mixture of oilfield waste water and production fluid within the disposal well building. Fluid migrated out on the gravelled access road and then north away from the well site and east out into an area of agricultural land before reaching the ditch bordering the west edge of Highway 35. Between October 5 and October 23, 2014, initial response and remedial work was conducted including free fluid recovery and disposal, a remedial excavation of impacted soil and reclamation of the remedial excavation. A total of 3.0 m3 of fluid was recovered from the surface of the spill area and disposed of at the Gibson Midale WPF. During the remedial excavation a total of 343.1 metric tonnes of impacted soil was excavated and hauled for disposal to the Gibson Heward Landfill. The excavation area was measured using differentially corrected GPS and revealed a total surface area of 1,159 m2. The area in the vicinity of the well head which was not scraped measured approximately 50 m2. Reclamation of the remedial excavation was completed by Gibson personnel. Approximately 40 m3 of clay and 230 m3 of topsoil was imported and applied throughout the remedial excavation. A grader was then retained to contour the surface of the reclamation area.

Laboratory results for soil samples obtained from the site indicate that a majority of the source produced water impact had been removed. Some residual impact remains in the soil at SP101 and SP103 where chloride concentrations of 1,830 and 466 mg/kg remain respectively. Soils in the vicinity of SP101 near the well head will need to be addressed during well site decommissioning as a complete source removal of impacted soil around the active well head would not be practical. Elevated EC and SAR levels at SP103 would warrant a period of crop growth and yield monitoring, however, because the area of impact is located on the gravelled clay turnaround crop growth monitoring is not feasible. Samples SP106, SP109 and SP113 each fell within SPIGEC moderately tolerant crop use for EC. Low chloride concentrations at each sample location indicates that elevated salinity levels are likely natural. The reclaimed areas should be placed back into regular crop rotation in 2015 with monitoring conducted during the peak growth seasons in 2015, 2016 and 2017 prior to harvest to ensure growth in the reclamation area is on par with control areas.
