30 Phase Two Conceptual Site Model Summary The Phase II Conceptual Site Model (CSM) illustrates both the present condition and the condition prior to remediation of the Phase II/RSC Property (Site). Figure 1 shows the site location and Figure 2 shows the lot configuration. There are two on-site buildings, a main building and an accompanying residential garage used for storage of vehicles. These buildings were used initially as a residential house and an accompanying residential garage, with the residential garage being used for vehicle storage and not as a commercial garage. JFM Environmental Limited (JFMEL) completed both a Phase I Environmental Site Assessment (ESA) and a Phase II ESA. The Phase I ESA identified three (3) Areas of Potential Environmental Concern (APEC) which led to the Phase II ESA. These APECs included 1) the on-site Fill throughout the Phase I property due to the importation of fill material of unknown quality, 2) the area near the west property boundary of the Phase I property due to the presence of an underground storage tank on the neighbouring west property due to the possible presence of gasoline and associated products stored in fixed tanks, and 3) the eastern part of the Phase I property extending to the eastern property boundary and the both the north and south property boundary on the eastern part of the Phase I property due to the presence of lead based paint on the window frames of the on-site main building. The building described as a frame garage (as labelled on the Current Plan of Survey) has not been used as a commercial garage for the maintenance and repair of vehicles. As the Potentially Contaminating Activities (PCAs) such as the maintenance and repair of vehicles did not occur in the residential garage it was not considered an enhanced investigation property. The Phase II ESA was designed to investigate the three (3) APECs through a soil and groundwater sampling program. Figure 3 shows the Phase I CSM. The Phase I CSM shows the Study Area within 250 m radius of the Site and the various land uses of the properties within the Study Area. The APECs are shown as on-site and the neighbouring property to the west of the Site. There is a railway to the west of Front Street S., to the west of the Site. There are no Areas on Natural Significance on- Site, adjacent or within 30 m of the Site. The nearest body of water is the St. Clair River to the west of the Site. No drinking water wells are located on-site. Work completed as part of the Phase II ESA included drilling of boreholes and installation of monitoring wells and subsequent soil and groundwater sampling and laboratory analysis. As a result of analytical results from on-site sampling, specifically soil sampling, remediation was undertaken. Remedial activities consisted of excavation of fill and placement of new clean fill in the excavated areas. Lead concentrations in some soil samples were greater than the Site Condition Standards (SCS) of the Soil, Ground Water and Sediment Standards for Use Under Part XV.1 of the Environmental Protection Act (April 15, 2011). The Standards used were Table 3, Full Depth Generic Site Condition Standards in a Non-Potable Ground Water Condition (Table 3 SCS). The more stringent Table 3 SCS coarse grained standards were used. The Site

31 is located in an area which is serviced by the Lambton Area Water Supply System (LAWSS) and the Study Area groundwater is not used for potable purposes. Shallow soil samples at depths less than approximately 0.2 metres below ground surface (mbgs) were taken in the spring and summer of The Contaminants of Concern (COCs) for which analysis was completed all had concentrations less than the Table 3 SCS, with the exception of lead. The source of lead was from the lead paint that was peeling and chipping off the outside window frames of the windows of the on-site main building. Some remedial activities took place in June 2013 prior to the commencement of the Phase II ESA in November These included excavation to a depth of approximately 0.2 mbgs in the areas from which samples with lead concentrations that were greater than the Table 3 SCS were obtained and then placement of clean fill in the excavated areas. These areas were in close proximity of the on-site main building. The windows and consequently the lead paint were removed from the Site and replaced with new windows. Soil samples taken during the drilling program of the Phase II ESA in November 2013 and for which analysis was conducted had lead concentrations less than the Table 3 SCS. Three (3) soil samples were taken in May 2014 and two (2) of the three (3) samples had lead concentrations (6 and 17 µg/g) which were less that the Table 3 SCS for lead (120 µg/g). The third sample had a lead concentration (263 µg/g) which was greater than the Table 3 SCS for lead. Further excavation and placement of clean fill was completed in May and June All samples had lead concentrations less than the Table 3 SCS (13 to 82 µg/g for eleven (11) samples) with the exception of one sample (160 µg/g). Further excavation and placement of clean fill in the vicinity of this sample was completed and the soil sample taken after this remedial action had a lead concentration (25 µg/g) less than the Table 3 SCS. The Site was considered to have been remediated with respect to lead contamination in the soil. Assessment of Environmental Concern Locations of Potentially Contaminating Activities Three potentially contaminating activities as defined by Table 2 of Schedule D of O. Reg. 153/04 were identified during the Phase I ESA. The areas associated with these potentially contaminating activities (PCAs) include; Location of an underground storage tank (UST) on the adjacent property at 111 Wellington Street Sarnia Ontario. This property is to the west of the Site. Area immediately surrounding on-site main building due to the presence of lead-based paint (designated substance) on the outside window frames. The specific area of concern is on the eastern half of the Site from the building to the property boundaries. Location of imported fill of unknown quality (various locations on-site)

32 The identified areas of potential environmental concern (APEC) and potential contaminants of concern (PCOCs) on-site or within the Phase I ESA Study Area are summarized below.

Lead based paint was historically used on the outside window frames of the on-site main building, Peeling paint and paint chips from window frames have fallen on the upper surface layers of overburden (fill), On-Site -Metals SOIL The three APECs were investigated through soil sampling, groundwater sampling and analysis. Samples were analyzed for metals, petroleum hydrocarbons (PHCs), and volatile organic compounds (VOCs) including BTEXs. Analytical results for the samples taken were below the standards for each respective parameter in the Table 3 SCS with the exception of lead concentrations in some soil samples. These results indicated that APEC #3 in the above table had been impacted by the presence of the lead based paint on the window frames of the main on-site building and needed to be further investigated and remediated to ensure that lead concentrations were below the Table 3 SCS. The results indicated that APEC #1 and APEC #3 in the above table had not been impacted by the PCA s.

33 Subsurface Structures The basement of the on-site main building is the only on-site subsurface structure. The basement of the main building extends approximately 2.2 mbgs. The completed utility locates identified the presence of two gas lines entering the Site. One gas line enters the Site from the east side of the property boundary. This gas line runs west toward the on-site main building and then curves north and enters the on-site main building on its south side. The other gas line enters the Site from the north property boundary, slightly east of the northwest corner of the property. This gas line runs south along the western property boundary at an approximate distance of between 0.7 metres and 1.2 metres east of the western property boundary. There is also a gas main on the Site. The gas main is located in the extreme northeast corner of the property and extends inward from the municipal sidewalk approximately 0.3 metres west and 0.7 metres south of the property boundary Buried utilities may have some interaction with the groundwater at the Site based on the depth to the groundwater table at the Site. Groundwater was encountered at the Site at depths between 2.14 and 2.36 mbgs. Although the possibility exists for the buried utilities to interact with groundwater, these depths to groundwater are greater than the typical depths (less than 2 mbgs) at which gas lines are installed. As the buried gas lines are most likely above the groundwater table it is not likely that they will pose as a preferential pathway for contaminant migration within the groundwater. Surface water infiltrating from the surface through the overburden in the vicinity of the utility corridors will most likely collect in the utility corridors which will be filled with materials with higher permeabilities than the native clay deposits and then infiltrate further into the overburden. Stratigraphy Physical Characteristics The soil stratigraphy was primarily uniform across the Site at the locations investigated through the borehole drilling program. The locations of the boreholes are shown on Figure 2. The stratigraphy as encountered is shown on the attached borehole logs. Three distinct soil layers were observed including fill in two of the three boreholes (BH1 and BH2) and surficial topsoil in one borehole (BH3). The two underlying layers consisted of a Silty Clay and an underlying Clay layer. The ground elevations in the vicinity of the Site are approximately 178 metres above sea level (masl). Figure 4 shows the location of the cross-sections, the borehole/monitoring well locations and the sampling locations for those samples taken prior to final remediation. Figure 5 is a northwest by southeast cross-section (AA ) and Figure 6 (BB ) is a northeast by southwest cross-section. Descriptions of the layers intercepted at the Site are presented in the individual borehole logs. Figures 5 and 6 represent the on-site stratigraphy as encountered in the boreholes drilled in November 2013, following preliminary remedial activities (excavation to a depth of 0.2 mbgs in east part of Site (Figure 2)) and prior to final remedial activities (excavation

34 to 0.6 mbgs in east part of Site (Figure 7)). In addition, Figure 7 shows the location of the crosssections, the borehole/monitoring well locations and the sampling locations for the verification samples taken during final remediation. Fill Material Observations of disturbed ground surface made at the time of the Phase I Site reconnaissance in October 2013 and historical information collected indicated that in-filling had occurred at the Site. It was known that some fill had been removed in June 2013 and replaced. The observed disturbance on the ground surface was most likely due to this activity. Other on-site areas where there was suspected fill and the ground surface was not disturbed most likely had fill brought in at the time of the original construction. Further observations were made during the Phase II work. Areas of the Site had a disturbed ground surface. Due to knowledge of the excavation activities that had taken place in June 2013 it was known that the absence of grass was a result of these activities. BH3 was drilled in an area where the excavation activities of June 2013 had taken place. Fill material, most likely from the time of the original construction was encountered in BH1 and BH2 which were completed as part of the Phase II work. These boreholes were completed at the rear (to the west) of the main building in an area undisturbed by the June 2013 excavation and infilling. This fill is described as dry brown gravelly fill with no suspect odours and/or discolouration observed. This fill material was observed under the on-site driveway and was inferred to be at depths from ground level to approximately 1.8 metres below ground surface (mbgs). The colour of the fill was grey, transitioning to brown at greater depths. Delineation of the areas of the Site that had been impacted by lead-based paint was completed through soil sample acquisition and laboratory analysis. Remediation of the Site consisting of excavation of fill in these areas to a depth of 0.6 mbgs was conducted in May and June 2014 after the drilling program included in the Phase II investigation. Fill material had been brought on-site and in-filled into the excavated areas. This new fill extends to 0.6 mbgs. Figure 7 illustrates the areas where excavation occurred. In BH3, the upper layer consisted of Topsoil to a depth of 0.3 mbgs, underlain by a SAND layer, to a depth of 0.6 mbgs. The Topsoil was described as dark brown, dry topsoil with some organics. The SAND layer was described as dry tan sand with trace organics. In BH1 and BH2 a narrow layer of SILTY SAND (0.05 to 0.15 m) was encountered in the Fill. SILTY CLAY Underlying the Fill was a native SILTY CLAY. This SILTY CLAY is described as dry and brown with a trace of silt and gravel or of gravel. Suspect odours and / or discolouration were not

35 observed within the SILTY CLAY layer or the CLAY layer. This layer varied in thickness from 1.2 m to 3.4 m. CLAY The three boreholes were terminated within a CLAY layer. This layer is described as grey clay with high moisture content. The clay layer extended beyond the maximum depth explored. Hydrogeological Characteristics Groundwater was intercepted at all three borehole locations within the CLAY layer. Table 1 summarizes the groundwater level measurements taken from the three monitoring wells. Based on groundwater measurements, the groundwater regime was interpreted to be within approximately 2.14 m of ground surface ( masl) across the Site. Based on the groundwater elevation contours, the horizontal hydraulic gradient was calculated at 0.08 in the northwesterly direction, as shown in Figure 8. The vertical hydraulic gradient was not calculated during this work program and has been assumed to have a downward direction. The existing ground surface topographical relief and the presence of St. Clair River approximately 135 m west of the Site suggests the regional groundwater has a northwesterly flow direction. Bedrock The bedrock is estimated to be at an approximate elevation of 152 masl and as such, is suspected to be at a depth greater than 25 mbgs. Water Table The depth to the water table as measured in the three (3) on-site boreholes varied from 2.14 mbgs to 2.34 mbgs. (June, 2014). The water table was within the CLAY layer. Section 41 or 43.1 There are no areas of natural significance located on the Site or wholely or partially within 30 metres of the Site property boundaries. The ph for the surface soil samples (less than 1.5 metres below ground surface (mbgs)) ranged from 7.58 to The ph for the subsurface soil sample (greater than 1.5 mbgs) was It is not necessary to apply Section 41 to the Site. The Site is not considered a shallow soil property. Overburden consisting of silty clay and clay was encountered in boreholes drilled to depths of greater than 6 m. Boreholes were terminated in the clay. There is no on-site water body. The Site is not adjacent to a water body and does not include land that is within 30 m of a water body.

36 Imported Fill Material Based on information presented in the Phase I ESA conducted by JFMEL, fill material has been historically used on-site. In the original construction of the main building and development of the Site fill was added. This fill material was observed under the on-site driveway and was inferred to be at depths from ground level to approximately 1.8 metres below ground surface (mbgs). In preliminary soil sampling and analysis conducted by the consulting firm, Bluewater Environmental Western Canada Inc. (BEWI), prior to the Phase II work, it was determined that the fill in some areas surrounding the on-site main building had lead concentrations greater than the Table 3 Site Condition Standards (SCS) for lead (lead impacted fill) to a depth of approximately 0.45 mbgs. The paint on the outside window frames was lead based and paint chips from the frames appeared to be the source of the elevated lead concentrations in the fill. The lead impacted fill was excavated and new fill was brought in and placed in the excavated areas. During further soil sampling investigations it was determined that areas on-site with lead impacted fill still existed to a maximum depth of 0.45 m. Further delineation of this fill was completed. In May and June 2014, the areas of the Site that had lead impacted fill were excavated to a depth of 0.6 m. Fill was brought in and placed in the excavated areas. Figure 7 shows the areas that were excavated and where soil was placed on the Site in May and June Figures 9 and 10 are cross-sections which show the vertical extent of the clean fill placed in the excavated areas. Proposed Structures Sarnia 5M Holdings Ltd. does not plan to build any buildings or structures at the Site. The existing on-site buildings are shown in Figure 2. Areas of Contamination Present Contamination The laboratory analyses of samples obtained after remediation had lead concentrations that were less than the Table 3 SCS. Although some samples had lead concentrations above the Table 3 SCS, those areas were excavated and clean fill was used to backfill the excavation area. Remediation activities consisting of excavation of lead impacted fill followed by infilling with clean fill occurred in May and June Verification sampling and analysis of the in-situ soil was completed following excavation of the lead impacted fill and prior to new fill being place in the excavation. No COCs were above the applicable level within the Table 3 SCS for this most recent and final verification sampling in June The elevated lead levels were inferred to originate from the lead paint on the outside window frames of the on-site main building. The windows and consequently the lead paint were removed and replaced with new windows. The clean fill was sampled and analyzed for metals prior to placement in the excavation. The analysis indicated that all parameters were at concentrations below the Table 3 SCS.

37 Contaminants Causing Contamination Based on the soil analytical results, lead within the soil was the contaminant detected at the Phase II property at concentrations above the applicable Table 3 SCS. As such, lead was considered a COC in the shallow surface fill. The lead contamination was shown to exist in various on-site locations, specifically in the area surrounding the on-site main building to depths of a maximum of 0.45 mbgs as found in certain samples. The locations and lateral extent of the areas that had been impacted with lead at the Site are illustrated in Figure 4. The interpreted vertical extent of the previous lead contamination is illustrated in the cross-sections, Figure 5 and Figure 6. Figures 9 and 10 are post remediation cross-sections and show the analytical results in the soil samples which are less than the Table 3 SCS. Groundwater samples collected at the Site, where investigated, were reported to be less than the Table 3 SCS. The initial round of groundwater sampling indicated elevated levels of chloroform within the groundwater, though no known source of chloroform existed at the Site. Following discussions with personnel from the accredited laboratory, the elevated chloroform samples were considered to be caused by a lack of preservative in the sample vials. An additional round of groundwater sampling was conducted to refute these results and was conducted using two separate laboratories. The analytical results from the additional round of groundwater sampling indicate that chloroform was present at levels less than the Table 3 SCS. As such, no contaminants were carried forward as COCs in the groundwater. Contaminated Medium Contamination due to lead was reported to be present within the soil / fill medium at the Site prior to remediation. The area of the Site where the concentrations of the COC, lead was above the Table 3 SCS was on the eastern half of the Site in the vicinity of the on-site main building. Soil samples taken at depths greater than 0.45 mbgs did not have lead concentrations greater than Table 3 SCS. The area which had lead concentrations greater than the Table 3 SCS was in the highest 0.45 m of the overburden. All parameters which were analyzed for within groundwater samples collected at the Site were reported to be less than the Table 3 SCS. Following remediation, the soil / fill at the Site was not considered contaminated. Contaminant Discharges The source of the elevated lead levels within the soil / fill was determined to be the lead-based paint on the outside window frames. Aging paint and resulting paint chips have landed on the on-site surface. Water in the form of precipitation and infiltrating surface water spread the paint into the overburden resulting in lead from the paint entered the on-site soils. Groundwater samples did not have lead concentrations elevated above the Table 3 SCS.

38 There is no longer any concern about further contamination from the lead-based paint as the windows and consequently the lead-based paint have been removed from the on-site main building and replaced with new windows. The soil with concentrations great than the Table 3 SCS was excavated and replaced with clean fill. Therefore there is no longer a contaminant source for discharge. Contaminant Migration Figures 5 and 6 illustrate the interpreted delineation of the lead contamination based on soil sampling and analysis results. Migration of the lead could have occurred as the paint aged and paint chips landed on the surface of the Site though the presence of surface water infiltrating into the on-site upper layer of overburden. Soil sampling results for the COC, lead with concentrations greater than the Table 3 SCS indicate that the lead migrated into the soil to a depth of less than o.45 mbgs. At present, as the source of the lead contamination, the window frames have been removed from the Site, and the lead impacted fill has been excavated from the Site, the migration of the COC lead is unlikely. Climate / Meteorological Conditions Precipitation landing on the Site would be the most likely source of migration of the COC, lead. However frozen ground conditions and snow coverage in the winter would have reduced the migration. The soil samples which had lead concentrations above the Table 3 SCS for lead were above 0.45 mbgs and above the water table which was measured in June, a time when water levels are higher. Temporal fluctuations in groundwater associated with seasonal precipitation fluctuations could possibly have had an influence on the distribution and migration of contaminants. As the lead contaminated soil and the source of the lead contamination on-site have both been removed the effect of climate and meteorological conditions on the migration of the COC, lead has been mitigated. Site Building Features There are two buildings on-site. The main building is a two-storey building. The main building has a basement with a poured concrete slab floor. The main building is located approximately at the centroid of the Site but slightly closer to the north of the Site, near to Wellington St. A onestorey residential garage is located in the southwestern corner of the property. This garage is used as a residential garage for vehicle storage for the on-site main building. It was not and is not used as a commercial garage.

39 The COC, lead did not and does not pose an issue with respect to soil vapour intrusions into the on-site buildings, the building heating, ventilating and air conditioning operations and with the subsurface utilities. Lateral and Vertical Distribution of the Contaminant, Lead Figures 5 and 6 illustrate the interpreted delineation of the lead contamination based on soil sampling and analysis results. The lead contamination was shown to exist in on-site soil samples, specifically on the eastern half of the Site in the area surrounding the on-site main building to depths of a maximum of 0.45 mbgs. The locations and lateral extent of the areas that had been impacted with lead at the Site are illustrated in Figure 4. The interpreted lead contamination delineation and the vertical extent of the lead contamination is illustrated in the cross-sections, Figure 5 and Figure 6. Depth to Water Table in the Area of the Lead Contaminated Soil The on-site water table as measured in November 2013 and June 2014 varied from 2.14 mbgs to 2.43 mbgs. The water table level in the vicinity of the lead contaminated soil was 2.14 mbgs in June 2014 and 2.33 mbgs in November This is illustrated in the four cross sections, Figure 5, Figure 6, Figure 9 and Figure 10. Table 1 shows the groundwater level measurements. Soil Stratigraphy in the Area of the Lead Contaminated Soil The soil across the Site is mostly uniform. The upper most layer of the overburden in the vicinity of the area in which the lead concentrations in the soil were greater than the Table 3 SCS was topsoil to a depth of approximately 0.6 mbgs. Some areas had granular fill consisting of a dry brown gravelly fill to a depth of approximately 0.5 mbgs. Underlying the top layer is a tan sand with a trace of organics to a depth of 1.2 mbgs. Underlying the sand is a dry brown silty clay to an approximate depth of 4.6 mbgs. The water table is in this layer at a depth of approximately 2.2 mbgs. Contaminant Features Figure 11 presents the human health and ecological contaminant pathway and receptor models. It represents on-site conditions prior to remediation. This figure identifies lead as the COC and the following: Release mechanisms Contaminant transport pathways Human and ecological receptors located on, in, or under the Phase II/RSC Property Receptor exposure points

40 Routes of exposure Figure 11 identifies the complete exposure pathways where receptors could possibly have made direct contact with COCs in soil and groundwater, or where they could possibly be indirectly exposed to COCs from soil and groundwater via vapour transport or other pathways. As the source of lead has been removed from the Site and the Site has been remediated by excavation and clean fill placement, Figure 11 represents conditions prior to remediation.
