Application for a Permit Under the Provisions of the Environmental Management Act
Tracking No. 456748 and Pre-Authorization No. 113162
We, Lhtako Gas and Convenience Store Ltd. (1535 Arbutus Road, Quesnel, BC V2J 5H8), intend to submit this application to the Director to allow ongoing containment and treatment of extracted groundwater from a past fuel release at the service station. A groundwater containment and treatment system is currently in place to extract, clean and return affected groundwater in the aquifer. The intent of the system is to prevent migration of contaminated groundwater beyond its current footprint and to treat extracted groundwater prior to return to the aquifer. The system is currently authorized under a short-term Approval. This Permit application is being submitted to allow for the ongoing operations of the system, with the goal of improving groundwater quality and protecting human health and the environment from migration of groundwater contamination.
The land upon which the groundwater containment system and its associated discharge points will be situated is within Quesnel Indian Reserve #1, Lots 1 and 2 CLSR 68290, Lot 23 CLSR 104099, and ATBC81 CLSR.
The maximum rate of effluent discharged from this facility will be 220 L/min. The operating period for this facility will be 24 hours/day, 7 days/week. The characteristics of the effluent discharged are as follows: benzene, toluene, ethylbenzene, xylenes, VHw, VOCs, EPHw, and PAHs, concentrations will be maintained below the Drinking Water Generic Numerical Water Standards as per Schedule 3.2 of the Contaminated Sites Regulation (as listed below).
Parameter | Maximum Concentration | Parameter | Maximum Concentration |
Benzene | 5 µg/L | Benzo(b+j)fluoranthenes | 0.07 µg/L |
Toluene | 60 µg/L | Chrysene | 7 µg/L |
Ethylbenzene | 140 µg/L | Dibenz(a,h)anthracene | 0.01 µg/L |
Xylene | 90 µg/L | Fluoranthene | 150 µg/L |
Styrene | 800 µg/L | Fluorene | 150 µg/L |
methyl tert-butyl ether (MTBE) | 95 µg/L | 1-methylnaphthalene | 5.5 µg/L |
VHw6-10 | 15000 µg/L | 2-methylnaphthalene | 15 µg/L |
EPHw10-19 | 5000 µg/L | Naphthalene | 80 µg/L |
Acenaphthene | 250 µg/L | Pyrene | 100 µg/L |
Anthracene | 1000 µg/L | Quinoline | 0.05 µg/L |
Benzo(a)anthracene | 0.07 µg/L | 1,3-butadiene | 1 µg/L |
Benzo(a)pyrene | 0.01 µg/L | 1,3,5-trimethylbenzene | 40 µg/L |
The type of treatment to be applied to the effluent prior to discharge is: filters to remove sediment followed by treatment of the water through two sequential activated carbon units which will remove dissolved hydrocarbons from the water. The treated effluent will be discharged to the subsurface via injection wells.
Any person who may be adversely affected by the proposed discharge and wishes to provide relevant information may, within 30 days after the last date of posting, publishing, service or display, send written comments to the applicant (by email at lhtakoproject@slrconsulting.com). A copy may also be sent to the Director (including reference to tracking number 456748 and pre-authorization number 113162), by email at industrial.waste.authorizations@gov.bc.ca. The identity of any respondents and the contents of anything submitted in relation to this application will become part of the public record.
