A. 
Definitions. In this division, the following definitions shall be applicable:
BLASTING
A method of loosening, moving or shattering masses of solid matter by use of explosive compounds to prepare stone for crushing, to prepare stone for building and/or ornamental use, or to prepare property for development.
PERSON
Any individual, partner, corporation, company, trustee or association, together with the respective servants, agents and employees thereof.
ROCK CRUSHER
Any device, machine, apparatus or equipment used either individually or in conjunction with any other device, machine, apparatus or equipment for the purpose of crushing, grinding, breaking or pulverizing rock or stone.
A. 
License required. No person shall operate a rock crusher or perform blasting in such a manner so that any dust, dirt or vibration from such operation shall, in any way, damage or injure any person or property within the City without obtaining a license for those purposes as provided herein. No person within the City shall operate a rock crusher or perform blasting in such a manner so that any dust, dirt or vibration from such operation shall, in any way, damage or injure any person or property within the City. All blasting within the City shall be performed according to the requirements of Ch. 307, Explosives and Fireworks, Wis. Adm. Code,[1] and all subsequent amendments thereto.

Editor's Note: See Ch. SPS 307, Wis. Adm. Code.
B. 
License application. Applicants for a blasting and rock crushing license must complete and return an application form furnished by the office of the City Clerk. At the time the application is submitted, a fee shall be paid via a certified check in an amount as set forth on the City of Onalaska Fee Schedule, which shall be reviewed annually. Operators shall apply a minimum of 60 days prior to anticipated operation start date. The office of the City Clerk shall refer all applications to the City Engineer. The City Engineer shall review the application and associated materials and furnish to the City Clerk a recommendation as to whether a license should be granted, modified or denied.
C. 
Issuance. The City Clerk shall issue a license based upon the recommendation of the City Engineer to the applicant. The license shall be valid until December 31.
D. 
Insurance required. Each license application shall be accompanied by a certificate of insurance identifying the City of Onalaska as a party insured in the amount of $500,000 for damage to property, and $500,000 for injury to one person and $1,000,000 for injury to more than one person caused by the blasting.
E. 
Renewals. All requests for renewals of permits hereunder shall be made at least 60 days prior to the expiration date of the permit.
F. 
Enforcement. Before renewal of any license issued under this section is refused or any license is revoked, cancelled, rescinded or terminated, the licensee shall be given written notice of any charges or violations against them or the reasons proposed for nonrenewal or revocation and shall have an opportunity to be heard before the Common Council.

A. 
Blasting procedures and controls.
1. 
Energy ratio. The allowable vibration of any blast at the nearest occupied or used building off the subject premises shall not exceed an energy ratio of 0.5 or resultant particle velocity of 1.35 inches per second based on the following formula:
Energy ratio = 0.5 = 10.823 f2 A2
Where:
f
=
frequency in cycles per second
A
=
amplitude or displacement in inches
Energy ratio = .274 V2
(V = resultant particles velocity expressed in inches per second)
2. 
Measurement of blasts. The operator of the quarry operation, when requested to do so by the City Engineer, shall measure and submit data to substantiate compliance with the above formula, and the operator of the quarry operation, when requested to do so by the City Engineer, shall measure air blast. This verification shall be performed by a seismological engineering firm acceptable to the City or by the City Engineer. Instrumentation shall be by seismograph similar to VME Seismology Model "B" and approved seismograph sound-measuring equipment or approved equivalents. All expenses for these tests shall be paid by the quarry operator.
3. 
Blasting log. A log in duplicate shall be kept of each blast on forms similar to the one on file with the office of the City Clerk. The original copy of this blasting log shall be filed with the City Clerk within 48 hours after the blast, and a copy shall be kept on file at the quarry office.
4. 
Cover material. Operators of quarries for building and/or ornamental stone removal shall cover Primacord®, other detonating cord or surface laid blasting devices with at least one foot of dirt or other suitable cover material.
