Phase 1 Environmental Site AssessmentRed River Co-Op 3455 Pembina HighwayBy Kelsey Berke, Holly Kajpust, Johanna Theroux,
Chris Piasta, Daniel Vermeulen
Purpose and Use
A Phase One Environmental Site Investigation was under undertaken on the Gas Station and Car Wash at 3455 Pembina Highway, at the corner of Pembina highway and Grandmont Ave. Red River Co–operatives requested a Phase One be done to take part in proper due diligence measures, prior to the sale of their property.
Purpose and Use
This Phase One Site Assessment will be completed under the following standards and regulations for a site located in Manitoba, Canada:
Canadian Environmental Protection Act Canadian Environmental Assessment Act Fisheries Act The Environment Act
Land Use
Climate Setting annual mean temperature of 2.3C annual total precipitation for the area is 514
mm prevailing winds are generally from the west
with speeds averaging 16 km/hr
Land Use
Ecological Setting The Red River Co-Op is situated in the prairie
ecozone site-specific setting is urban very few terrestrial species that habitat our
site area The Red River is located adjacent to our site
Land Use
Current Land Use Red River Co-op Gas Station and Carwash Petroleum is the Co-Op’s main retail item, others
items include: carwash services and convenience food
the south of our site is a vacant lot North of the Co-Op is Autopac Agency and Mac
Convenience store west of the Co-op is a residential housing area . Approximately 150 m west of our site, across
Pembina Highway is the Red River

Potential Impacts Petroleum spill or leak Carwash cleaning products Other contaminants
Contaminants and Criteria
Table:
Contaminants and Criteria
Carwash Chemicals carwash substances are all from the Turtle Wax Company majority of chemicals used in these products do not have any
known adverse effects on the environment Methanol can be dangerous to aquatic organisms if released in
high quantities petroleum distillates are volatile organic compounds, which can
cause long-term health effects If any of these chemicals are burned the compounds that they
can decompose to can very harmful to the environment For handling and transport the company must follow the
Manitoba Law of Dangerous Goods Handling and Transportation Act
Contaminants and Criteria
Fuel Products Gasoline and Diesel
stored in underground storage tanks and contain extremely flammable liquid and vapor hazards
mixtures of volatile organic compounds The main compounds from these products
associated with pollution problems are: BTEX; lead and trace elements; hydrocarbons; aromatics; PAHs; MTBE; ethylene dichloride; and naphthalene
Contaminants and Criteria
Fuel ProductsPropane
natural gas liquid and is flammable at high pressures
contains hydrocarbons such as ethane and ethylene, propylene, butane, and pentane
non-toxic, but asphyxiation can occur displacing the oxygen by propane
Contaminants and Criteria
Fuel ProductsHeating Fuel, Solvent, and Kerosene
combustible liquids and vapors Kerosene and solvents can be extremely volatile If solvent vapor enters the soil or waterways,
explosion hazards become a serious concern
Contaminants and Criteria
Other Products Motor Oils, Transmission Fluid, and Antifreeze
Motor oils are not known to produce significant adverse health effects or critical hazards to the environment
Incomplete combustion of motor oil releases aldehydes, hydrogen sulfide, carbon oxides, sulphur, calcium, magnesium, sodium and zinc into the atmosphere
Decompositions and combustion of transmission fluid releases the same products including carbon monoxides and smoke
Contaminants and Criteria
Other ProductsBlast Off
aerosol spray solvent cleaner for metallic surfaces It is an aromatic hydrocarbon no significant environmental hazards of this
compound, but seepage of this material into soil and waterways is should be prevented to avoid detrimental effects
Property Records and Site Characteristics Site Plan
Property Records and Site Characteristics Regional Geology
Description of Geology Manitoba Lowland physiographic region – Glacial Lake Agassiz lacustrine clay and sediment deposits Approx. 150 meters from the site, stream banks consist of fine grained
alluvium consisting of layered clay, silt, and sand deposits Below the glacial till overburden, lies the bedrock layer which consists of
a fractured and jointed limestone Red River formation, consists of dolostone, limestone, shale, basal
sandstone, dolomite, and carbonate rock Low soil permeability caused by high clay composition directs much of
the precipitation on the site directly overland into the Red River through hydraulic head difference
Property Records and Site Characteristics Regional Geology
Description of Soil The soil on site is part of the St. Norbert series
which consists of moderately well to well drained Orthic Dark Gray Chernozemic soils
moderate runoff capabilities associated with a low infiltration rate; and moderately slow to slow permeability
Soil pH approx. neutral at 6-6.7

Site Visit
site visit of the Red River Co-op Grandmont Gas Bar was conducted on February 29, 2012
General building and site characteristics were noted The Red River is adjacent to this property and there is
no potential for surface flow to enter the river This site uses city water as the drinking water source
and wastewater is discharged into the city sewers Another site visit was conducted on March 29, 2012 to
take pictures of the study site
Interview
On February 29, 2012 an interview was conducted with the owner/operator of the Red River Co-op Grandmont Gas Bar, Mitch Tabak
characteristics, history, and adjacent property information were discussed
On the site, there is: the main store building the car wash centre ten gas pumps propane tank
there has never been a Phase 1 Environmental Site Assessment conducted for this site
Limitations
The site visit was conducted at the end of February; therefore the majority of the ground still had snow and ice present
landowner would not allow us to have a copy of the site plan
records for the background information regarding the site were spaced apart
Conclusions
notable possible contaminants of our site include: petroleum hydrocarbons, cleaning contaminants associated with the touchless carwash, and vehicular contaminants
conducted the ESA to determine the potential for migration of contaminants off site
The station is a new within the last 4 years, and uses the most up to date equipment Has spill response procedure Carwash runoff localized to single drainage pipeBased on our site analysis, it appears that there are no
contaminants currently being released into the soil, water or air on our site
