A. 
Use Of Explosives.
1. 
All blasting shall be conducted between sunrise and sunset.
a. 
The City Engineer may specify more restrictive time periods based on public requests or other relevant information according to the need to adequately protect the public from adverse noise.
b. 
Blasting may, however, be conducted between sunset and sunrise, if:
(1) 
A blast that has been prepared during the afternoon must be delayed due to the occurrence of an unavoidable hazardous condition and cannot be delayed until the next day because of potential safety hazard could result that cannot be adequately mitigated;
(2) 
In addition to the required warning signals, oral notices are provided to persons within one-half mile of the blasting site unless persons have requested in writing they not be notified; and
(3) 
A complete written report on the blasting at night is filed by the person conducting the blasting activities with the City Engineer not later than three (3) days after the night blasting. The report shall include a description in detail of the reasons for the delay in blasting including why the blast was actually conducted, the warning notices given, and a copy of the blast report required by this Chapter.
2. 
Blasting shall be conducted at times announced in the blasting schedule, except in those unavoidable hazardous situations identified in the permit and plan, where operator or public safety require unscheduled detonation. When no schedule is provided, the Public Works Inspector and Fire Department Communication Office shall be notified prior to any blasting.
3. 
During open quarrying, warning and all clear signals of different character that are audible within a range of one-half mile from the point of the blast shall be given. Each person within the permit area and each person who resides or regularly works within one-half mile of the permit area shall be notified of the meaning of the signals through appropriate instructions. These instructions shall be periodically delivered or otherwise communicated in a manner which can be reasonably expected to inform such persons of the meaning of the signals. Each person who conducts surface mining activities shall maintain signs in accordance with state regulations.
4. 
Access to an area possibly subject to flyrock from blasting shall be regulated to protect the public and livestock. Access to the area shall be controlled to prevent the presence of livestock or unauthorized personnel during blasting and until the blaster who conducts the blasting activities has reasonably determined the following:
a. 
That no unusual circumstances, such as imminent slides or undetonated charges, exist; and
b. 
That access to and travel in or through the area can be safely resumed.
5. 
Except where lesser distances are approved in the pre-blast survey, based on seismic investigation or other appropriate investigation, blasting shall not be conducted within the following:
a. 
Three hundred (300) feet of any building used as a dwelling, school, church, hospital, or nursing facility; and
b. 
Three hundred (300) feet of facilities including, but not limited to disposal wells, petroleum or gas storage facilities, municipal water storage facilities, fluid transmission pipelines, gas or oil collection lines or water and sewage lines.
c. 
Pre-blast surveys will be performed at the expense of the Contractor/Developer. Minimum qualification for performing a pre-blast survey shall be a person who has been employed in the blasting field for a minimum of two (2) years.
d. 
Owners of properties within three hundred (300) feet and requiring a survey shall be given written notice of the proposed blastings and can accept or reject the offer of a survey. Preblast surveys shall consist of a minimum of 35mm photographs. However, in some cases, additional documentation, such as technical reports and video tape, may be required. The City Engineer shall be allowed access to the survey within forty-eight (48) hours of written notice. The survey shall be kept on file for three (3) years after conclusion of blasting operations.
6. 
Flyrock, including basted material traveling along the ground, shall not be cast from the blasting vicinity more than half the distance to the nearest dwelling or other occupied structure and in no case beyond the boundary line of property owned or leased by the permittee or beyond the area of regulated access required under paragraph 4 above.
7. 
Blasting shall be conducted to prevent injury to persons, damage to public or private property outside the permit area, adverse impacts on any underground mine and change in the course, channel or availability of ground or surface waters outside the permit area.
8. 
In all blasting operations, except as otherwise authorized in this Section, the maximum peak particle velocity shall not exceed one (1) inch per second at the location of any dwelling, public building, school building, church or commercial or institutional building. Peak particle velocities shall be recorded in three (3) mutually perpendicular directions. The maximum peak particle velocity shall be the largest of any of the three (3) measurements. The City Engineer may reduce the maximum peak particle velocity allowed if he determines that a lower standard is required because of density of population, land use, age or type of structure, geology or hydrology of the area, frequency of blasts or other factors.
9. 
If blasting is conducted to prevent adverse impacts on any underground mine and changes in the course, channel or availability of ground or surface water outside the permit area, then the maximum peak particle velocity limitation of paragraph 8, above, shall not apply at the following locations:
a. 
At structures owned by the person conducting the blasting activity and not leased to another party; and
b. 
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 City Engineer prior to blasting.
10. 
Equation For Maximum Weight. Equation for maximum weight of explosives to be detonated within any eight-millisecond period may be determined by the formula W = (D/50)2, where W equals the maximum weight of explosives, in pounds that can be detonated in any eight-millisecond period and D equals the distance, in feet, from the blast to the nearest dwelling, school, church, or commercial or institutional building.
11. 
Airblast Limits. Airblast shall not exceed the maximum limits listed below at any dwelling, public building, school, church, or community or institutional building outside the permit area.
