A traffic control plan acceptable to ____________________ (jurisdiction name) detailing signing, flagging, temporary road closures, and detour routes for blasting operations must be filed before the blasting permit is issued.(3) Preblast notification plan. A plan outlining preblast public notifications, structural inspections, and blast effect monitoring within a specified distance of the blasting is required before the blasting permit is issued. (a) Separation distance. The distances from the blasting where the notification, preblast structural inspection, and blast monitoring is required must be determined by the scaled distance formulas described below. Blasting will not be permitted until the notification and inspection requirements are completed.(b) Scaled distance formulas.(i) The distance from the blast within which: (A) Notification of all occupied structures is required: Da = 90 w;(B) Inspection of all occupied structures is required: Db = 75 w;(C) Monitoring of selected structures is required: Dc = 60 w.(ii) In the above formulas: (A) Da, Db, and Dc are the actual distances in feet from the closest point in the blast.(B) w is the square root of the maximum weight of the explosives in pounds detonated with a minimum 8 millisecond from another detonation event.(c) Notification letter. The preblast notification must consist of a letter advising all residents within the distance (specified in WAC 296-52-720 section 10 (3) (b)) of the blasts. The letter must include the intent of the blasting program, its anticipated impact on local residents, the proposed duration of blasting activities, and provide telephone numbers for public contact. Distribution of this notification must be made a minimum of seven days before the start of blasting. The source of the chart is 121.8507, Bureau of Mines, U.S. Department of Interior, 1980.(d) Preblast inspection. A preblast inspection of resident's property must be offered to all residents within the distance (specified in WAC 296-52-720 section 10 (3) (b) above) of the blasting at no cost to the resident and will be preformed by a qualified third party who is not an employee of the contractor.

(4) Blast-plan compliance inspections. Blast-plan compliance inspections may be required for every blast until the operator can demonstrate an ability to safely blast according to the blast plan and control the extraneous effects of blasting such as flyrock, noise/air blast, and ground vibration. If more than two blasting inspections are required, an additional fee of ____________________ (insert dollar amount) per blast inspection will be assessed.(5) Monitoring. All blasts which require monitoring by section 10 (3) (b) are to be monitored using blast monitoring equipment designed for the purpose and carrying a certificate of calibration dated within the previous twelve months. The blast monitors must record peak particle velocity and frequency in three orthogonal directions and air over pressure. Monitored shots in which the pounds detonated per an 8-mil-lisecond time increment is less than ten pounds, one blast monitor is required. When ten or more pounds is detonated per an 8-millisecond time interval, two or more blast monitors are required. All blast-monitoring records are to be signed and submitted to ____________________ (jurisdiction name) within twenty-four hours of each blast.(6) Maximum peak particle velocity. The maximum peak particle velocity in any seismic trace at the dominant frequency allowed on any residential, business or public structure designed for human occupancy is to be determined by the chart in WAC 296-52-67065(1).(7) Air blast. The maximum air blast over pressure permitted at the closest residential, business or public structure designed for human occupancy is not to exceed 133 dBL @ 2.0 Hz hi pass system per WAC 296-52-67065(3). The source of this regulation is 121.8485, Bureau of Mines, U.S. Department of Interior, 1980.(8) Utilities.
