The maximum peak particle velocity allowed is one and one-half (1.5) ips. Applicants requesting to exceed this velocity may apply to the Board of Adjustment for a determination as to whether such a variance would be in the public's best interest.
The permittee shall submit a pre-blast design to the City Engineer at least ten (10) days prior to the Board of Adjustment meeting.

Such pre-blast design shall also include:
The intended maximum peak particle velocity and minimum scaled distance, where applicable, for such blasts;
The dates and time periods of such blasts; and
Pre-blast surveys of structures within one hundred (100) feet of the blast area. The pre-blast surveys shall be performed by a registered engineer.

Before any permit referred to in this Chapter shall have been issued to do blasting, the applicant for such permit shall file evidence of sufficient comprehensive general liability insurance to indemnify the City, or its inhabitants, against any damages arising from blasting; said liability insurance shall be provided by a responsible company, licensed to do business in the State of Missouri and shall have a minimum coverage of five hundred thousand dollars ($500,000.00) per person, five hundred thousand dollars ($500,000.00) per occurrence, five hundred thousand dollars ($500,000.00) per property damage, with an umbrella coverage of one million dollars (1,000,000.00). The insurance certificate, including a rider specifically covering the insured for doing blasting (blasting collapse and underground), shall be required with the permit application. In specific cases where blasting is being proposed within one thousand (1,000) feet of any dam, an additional rider for the endorsement of increased limits for a specific job shall be required at the sole discretion of the City Engineer.
[R.O. 2006 §520.080; Ord. No. 802 §8, 8-19-1996]
In all blasting operations, except as otherwise authorized in this Chapter, the maximum peak particle velocity shall not exceed one and one-half (1.5) inches per second at the location of any structure. Peak particle velocities shall be measured in three (3) mutually perpendicular directions.
The maximum peak particle velocity shall be the largest of any of these three (3) measurements, and shall not apply at the following locations:
Flyrock, including blasting material traveling along the ground, shall not be cast from the permit area.
Access to an area possibly subject to flyrock from blasting shall be regulated to protect the public. Access to the area shall be controlled to prevent the presence of unauthorized personnel during blasting until an authorized representative of the person conducting the blasting activity has reasonably determined:
All blasting shall be conducted so as to prevent injury to persons and damage to public or private property outside the permit area.
Before firing any blast, all means of access to the danger zone (the extent of which shall be determined by the blaster, but in no case to be closer to the explosive than the blaster himself/herself, or three hundred (300) feet, whichever is more) shall be effectively guarded to exclude all unauthorized personnel. The blaster shall then sound a warning of sufficient intensity and duration to be distinctly audible to all persons within the danger zone and all such persons shall retire beyond the danger zone. The danger zone shall then be examined by the blaster to make certain that all persons have retired therefrom to a place of safety. No blast shall be fired while any person is in the danger zone.
When the point of explosion is within three hundred (300) feet of a roadway, the blaster shall, just prior to the blast, designate a sufficient number of employees of the operator, each carrying a red warning flag, to stop all vehicular and pedestrian traffic on each possible route of travel within three hundred fifty (350) feet of the point of explosion until the blast has been fired.
No person shall return to the danger zone until permitted to do so by the blaster as announced by audible or visual signal.
Immediately following the blast area shall be examined by the blaster for evidence of misfired charges.
A complete record shall be kept by the blaster showing the number of holes, the amount of explosive used per hole, amount of explosive used per delay, length of delay, all misfires and method of disposal of misfires.
[R.O. 2006 §520.090; Ord. No. 802 §9, 8-19-1996]
A summary of the records for each blast, including seismograph reports shall be submitted to the City Engineer at weekly intervals, for blasts occurring the previous week. The record shall contain the following data for each blast:
Name of the permittee conducting the blast;
Location date and time of the blast;
Direction and distance in feet, from the blast to the monitoring device;
The number of holes drilled;
The maximum weight of explosives in pounds used in any hole;
Maximum weight of explosives in pounds used per delay;
Length of delay;
The total weight of explosives in pounds used in the blast;
Peak particle velocity at the testing location;
Name of company and the person taking the seismograph reading; and
Affidavit of company monitoring the blast, certifying the accuracy and truth of the reading obtained from the seismograph.
Monitoring shall be preformed by an independent firm, retained and compensated by permittee, who is responsible for submittal of the data directly to the City. The monitoring shall be performed by an engineering technician working under the direction of a registered professional engineer. Tabulated data (provided for in Section 520.090(A)) shall be submitted to the City at weekly intervals. The firm shall be responsible for notifying the City within one (1) hour of any blast exceeding the permitted values. Work shall be stopped and the City notified immediately if any blast exceeds two (2) ips.
The City Engineer may suspend blast monitoring after the data from five (5) blasts is submitted if, at his/her determination, monitoring is not necessary to protect the public and when no individual blast exceeded one (1) ips. All blasts over one (1) ips must be continuously monitored. The City Engineer may reimpose the monitoring requirements at his/her sole discretion. The suspension of monitoring does not relieve the permittee from any other requirements of this Chapter. The permittee shall still be required to supply the data specified in Section 520.090(A).
[R.O. 2006 §520.100; Ord. No. 802 §10, 8-19-1996]
The City Engineer or any authorized Police Officer, may, at any reasonable time, inspect premises, buildings and installations used for storage or sale of explosives or blasting agents, or any premises on which blasting operations are being conducted for the purpose of determining whether the provisions of this Chapter are being complied with.

Any permittee who violates any permit condition or who violates any other provision of this Chapter may be assessed a penalty, and/or have his/her permit revoked and future permits refused. Such penalty shall not exceed five hundred dollars ($500.00), and/or thirty (30) days imprisonment for each violation. Each blast may be deemed a separate violation for purposes of penalty assessments. In determining the amount of the penalty, consideration shall be given to the permittee's history of previous violations, the seriousness of the violation, including any irreparable harm to the environment or property damage and any hazard to the health or safety of the public.
[R.O. 2006 §520.130; Ord. No. 802 §13, 8-19-1996]
