FILE: ENW.EENW03295-01 | MAY 10, 2019 | ISSUED FOR USE EXECUTIVE SUMMARY Foreword Rohit Land St. Albert West Ltd. (Rohit) retained Tetra Tech Canada Inc. (Tetra Tech) to conduct a Phase I Environmental Site Assessment (ESA) of the properties identified as Lot A, Plan 9321471 and Alberta Township System (ATS) NW 06-054-25 W4M, NW 07-054-25 W4M, and SW 07-054-25 W4M (the site) in the City of St Albert, Alberta. Figure 1 shows the site location, and Figure 2 shows the detailed site plan. The objective of the Phase I ESA was to comment on whether any past or present land use, either off-site or on-site, may have a potential to cause environmental impairment of the site. Tetra Tech understands that Rohit requires this assessment as part of future purchase and development of the site. The site is an irregular-shaped property approximately 250 m south of Secondary Highway 633 (Villeneuve Road) and bounded by a drainage ditch to the north, Ray Gibbon Drive to the east, Range Road 260 to the west, and Township Road 540 (Giroux Road) to the south in St. Albert, Alberta. The site is primarily agricultural land, with an existing natural gas lease on the northeast portion of the site, and two former landfills on the northeast (Pit 1) and central west (Pit 2) portions of the site, respectively. The site is zoned primarily as “UR” Urban Reserve, with the exception of the areas around former landfill Pits 1 and 2, which are zoned as “S-DC” Specific Development Control. Potential for Impairment from On-Site Source(s) There were four (4) on-site sources identified that might have potential to cause environmental impairment to the site through the historical or current land use. Table i, below, summarizes the potential on-site concerns. Table i: Potential On-Site Source Summary Potential On-site No. Information Source Tetra Tech Evaluation Source Previous assessments identified boron and Historical records, personnel 1 Former Landfill Pit 1 chloride concerns in groundwater. Landfill closure interviews documentation is not apparent. Previous reports could not confirm if groundwater Historical records, personnel 2 Former Landfill Pit 2 concerns reported at Pit 1 affect Pit 2. Landfill interviews closure documentation is not apparent. Abandonment and reclamation of the on-site Cedar Creek Energy 3 Historical records, site visit natural gas well, shack, and associated Ltd. natural gas well infrastructure is not complete. Three (3) abandoned and reclaimed former oil/gas Three (3) Encana wells were noted on-site. Materials used during 4 Historical records former oil/gas wells drilling and/or production represent potential environmental concerns. Potential for Impairment from Off-Site Source(s) There were no off-site sources that might have potential to cause environmental impairment to the site through the historical or current land use. i RPT - Phase I ESA NW 6, NW and SW 7-054-25 W4M IFU.docx PHASE I ESA | ROHIT LAND ST. ALBERT WEST LTD. FILE: ENW.EENW03295-01 | MAY 10, 2019 | ISSUED FOR USE Based on the present study, Tetra Tech recommends that closure proceedings for each of the former landfills be completed, and that post-closure monitoring requirements be established for the former landfills in consultation with Alberta Environment and Parks. Further, abandonment and reclamation of the on-site natural gas pipeline and wellsite should be pursued with the facility owner. If development proceeds in the areas of the on-site former oil/gas wells identified during this study, any visually stained or odorous materials identified during development should be referred to a qualified environmental consultant. Alternately, intrusive investigation of these former wellsites may confirm whether environmental concerns exist at these locations prior to land development. ii RPT - Phase I ESA NW 6, NW and SW 7-054-25 W4M IFU.docx PHASE I ESA | ROHIT LAND ST.
