Blasting Permit Application

Looking to the future

The City has taken steps to ensure future blasting activity is carefully considered by Council, both through new bylaws to regulate retaining walls and dust emissions, as well as a review of blasting permit processes. A report will be presented to Council for consideration within 2016.

The City is also engaging citizens and partners in an update the Colwood Official Community Plan. It will begin a conversation about where and how future development takes place in Colwood, and whether hillside development which requires long term blasting is part of the City’s long term plan.

The City requires that blasting companies are insured and that they issue notification to neighbouring property owners.

The blasting company must provide notification to the occupants of all buildings within 300 metres of the site that includes:

  • a description of the work being undertaken
  • dates and duration of the work
  • methods to safeguard persons and property
  • signals and warning methods
  • blasting company contact
  • insurance company contact

If a Blasting Company and/or Developer removes soil and/or rock off site that exceeds 200 cubic meters, a Blasting Permit and Soil Deposit Permit is required at the time of applying for a Blasting Permit. 

Blasting is regulated by WorkSafeBC

WorkSafeBC oversees blasting in British Columbia. They are responsible for issuing Blasting Tickets to qualified individual and ensuring safe blasting practices. 

Warning Signals

WorkSafeBC considers proper blasting notification as follows:

  • 12 short audible whistle signals followed by a 2 minute pause;
  • Blast will be detonated;
  • A longer whistle signal to indicate 'All Clear' after detonation.

Hours of Blasting

  • Monday through Thursday: 8:30 a.m. to 4:00 p.m.
  • Friday only: 8:30 a.m. to 3:00 p.m.
  • Saturdays, Sundays, & Statutory Holidays: No Blasting Permit

Pre-blasting surveys

Where explosives are employed within sixty (60) metres of any building, bridge, dam, or other structure the holder of the permit must retain an independent insurance adjuster, at the permit holder’s cost, to complete a pre-blast survey. The survey shall itemize the condition of each surveyed structure existing prior to detonation and shall be supported by photos.
