For the West Fork 12-Mile Gravity Sewer Project blasting and mechanical methods of rock removal is
anticipated. The duration of these operations will be determined upon rock location, depth, and
hardness. It is anticipated that the contractor will perform blasting along the pipe corridor (where
allowed) in the early stages of the project for the full length of the alignment. Areas where rock removal
is required but not allowed, mechanical methods will be used. Refer to the attached Hazen
