Section 520.010 Title.

[Ord. No. 2761 §1(150.010), 3-19-2002]
This Chapter shall be known as the "Blasting Regulations" and may be cited as such and will be referred to in this Chapter as the "code".

Section 520.020 Severability.

[Ord. No. 2761 §1(150.020), 3-19-2002]
In any case where a provision of this code is found to be in conflict with a provision of any other ordinance or other legislation of the City existing on the effective date of this code, the provision which establishes the higher standard for the promotion and protection of the safety, welfare and health of the people shall prevail. If any part of this Chapter should be declared invalid for any reason, such decisions shall not affect the remaining portions of this code.

Section 520.030 General Provisions.

[Ord. No. 2761 §1(150.030), 3-19-2002]
Blasting will be permitted in accordance to these blasting regulations. Blasting shall be done only by people experienced in the handling of explosives and in accordance with the recommendations of the AGC Manual of Accident Prevention in Construction and OSHA regulations. In locations where flying rock may be present, additional overburden shall be ready for use and/or in place before denotation. All trenching operations utilizing explosives shall be suitably backfilled to prevent any fly rock endangerment to persons or property. The use of these procedures does not relieve the contractor of responsibility for damage to life and property but acts only as an added assurance to the owner that damage will not occur.
The Public Works Department and Fire Department will be the authority regarding the storage, handling, use and control of explosives used in construction projects.
The requirements of the current Fire Code regarding explosives and blasting agents, as adopted by the City of Harrisonville, shall be considered part of these blasting regulations.
The contractor shall be responsible for all damage caused by the blasting operations and shall be responsible for responding to all complaints. Suitable methods shall be employed to confine all materials lifted by blasting within the limits of the excavation or trench. All rock, which cannot be handled and compacted as earth, shall be kept separate from other excavated materials and shall not be mixed with backfill or embankment materials except as specified or directed.
The handling and use of explosives shall conform to the regulations of the Federal Bureau of Alcohol, Tobacco and Firearms and the Department of Transportation.
NFPA 495, ATF Publication 5400.7 and DOT CFR 49 may be used as references in enforcing these regulations.

Section 520.040 Definitions.

In all blasting operations, except as otherwise authorized in this Chapter, the maximum peak particle velocity shall not exceed one and one-half (1½) 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:
At structures owned by the person conducting the blasting activity and not leased to another party; and
At structures owned by the person conducting the blasting activity and leased to another party, if a written waiver by the lessee is submitted to the Licensing Officers prior to blasting.
Fly rock, including blasted material traveling along the ground, shall not be cast from the permit area.
Access to an area possibly subject to fly rock from blasting shall be regulated to protect the public and livestock. 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:
That unusual circumstances, such as imminent slides or undetonated charges, exist.
That access to and travel in or through the area can be safely resumed.
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 closer to the explosion 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 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 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, the 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, all misfires and method of disposal of misfires.
All guidelines for the use, handling and transportation contained in the current Fire Code shall be adhered to, except where superseded by this Blasting Code.

Blaster shall follow all State and Federal regulations concerning blasting operations.
The permittee shall inform all utilities located within three hundred (300) feet of the blast area of the blasting operations, the times and dates.
All blasting operations shall be conducted by experienced, trained and competent persons who understand the hazards involved.
Explosives shall not be stored within the City limits of Harrisonville overnight.
The transportation of explosives shall conform to DOT, NFPA the Fire Code and ATF regulations.

Name of the permittee conducting the blast;
Location, date and time of the blast;
Testing locations;
Direction and distance in feet from the blast to the monitoring device;

Work shall be stopped and the City notified immediately if any blast exceeds two (2) ips.
The Licensing Officer may suspend blast monitoring after the data from five (5) blasts is submitted if, at their 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 Licensing Officer may reimpose the monitoring requirements at their 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.
