Upper Tank Farm

 

About Upper Tank Farm

Environment Yukon has formally designated the former Upper Tank Farm and nearby properties in Whitehorse as a contaminated site. Soil and groundwater contaminated with petroleum hydrocarbons at lower depths are present on the property.

Designation gives the government greater oversight of remediation activities on the property so as to ensure the protection of human health and the environment. The designated property lies between Hamilton Boulevard and the Hillcrest and Valleyview neighbourhoods.

As of January 2015, the property owners have remediated an 8.39 hectare portion of the site to territorial standards.

Designation Process

Development of a designated site can take place once contamination has been dealt with in accordance with a government-approved plan of restoration (a clean-up plan). The government issues a Certificate of Compliance once applicable standards are met.


Environment Yukon first designated the 55.9 hectare former Upper Tank Farm property as a contaminated site on January 5, 2011 in accordance with the Contaminated Sites Regulation (CSR) and the Environment Act.


A Certificate of Compliance was issued for an 8.39 hectare portion of the Upper Tank Farm on January 29, 2015, following a 14-day public review. On the same day, the Department of Environment issued a revised “Notice of Designation of the Former Upper Tank Farm and Nearby Properties as Contaminated Site” in accordance with the CSR and the Environment Act.

With respect to the public review, the Notice of Intent to Designate for the revised designation was issued on December 3, 2014. A 14-day review period ran from December 10, 2014 to December 24, 2014. Comments were received only from the City of Whitehorse.

Remediation

Remediation, or treatment, of contaminated sites in Yukon is considered successful if the level of contaminants remaining in the soil and groundwater is below the standards set out in the CSR for the intended land use, or if a risk assessment demonstrates that the risks to humans and the environment are within established levels.

Remediation work on the former upper tank farm site that began in the 1990s cleaned up much of the contamination. However, soil and groundwater contaminated with petroleum hydrocarbons at lower depths has the potential to affect future property users or off-site receptors (nearby properties and water bodies).


Sampling to confirm residual contaminant levels must be completed in accordance with all relevant protocols. In the case of groundwater contamination, several sets of acceptable sampling results must be obtained over a number of years in order to demonstrate that remediation has been successful.


Contaminated land that has been successfully remediated, with a Certificate of Compliance to attest to this, can be developed. Currently there are five designated contaminated sites in Yukon; two of these have been remediated in their entirety and have received Certificates of Compliance. One designated contaminated site has been partially remediated.
