  1. Can you publish what time the blasts are scheduled for?

  2. HI and thanks for your comment. The contractor can usually tell us if they plan to blast in morning or afternoon but often the timing is based on conditions on the ground such as delivery of materials, wind and progress made during prior blasts. We will do our best to add approximate times in the future per your request - at least to say morning or afternoon or more when possible. With the tunneling work starting, we may start to have more than one blast per day. Thanks for your interest!
