§ 252-1 Definitions.

The following definitions shall apply in the interpretation and enforcement of this chapter:
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.

§ 252-2 Operation.

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. SPS 307, Explosives and Fireworks, Wis. Adm. Code, and all subsequent amendments thereto.

§ 252-3 Permit.

A. 
Permit required. No person within the City shall operate a rock crusher or perform blasting who does not possess a proper permit therefor from the City.
B. 
Applications. All applications for permits hereunder shall be made in writing upon the written form provided by the City and distributed by the City Clerk. All applications for permits hereunder shall be signed by the applicant and filed with the City Clerk at least 60 days prior to the permit period. The City Clerk shall immediately refer all applications for permits hereunder to the Director of Public Works. The City Clerk shall issue a permit hereunder only after first receiving the recommendation of the Director of Public Works, the duly executed certified check for the permit fee as hereinafter provided and the submittal of the plan of operation, if required, as approved by the Director of Public Works.
C. 
Certified check. Each application for a permit hereunder shall be accompanied by a certified check in the sum of the required permit fee as hereinafter provided, or a renewal thereof, the same to be payable to the City.
D. 
Plan of operation. Each application for a permit to perform blasting or operate a rock crusher hereunder or renewal thereof shall be accompanied by a plan of operation which shall include: methods of screening from adjacent properties, hours of operation, hours of blasting and operation of rock crusher, dust and noise control, blasting procedures, location and height of stock piles, whether a rock crusher will be needed and how often, water supply, drainage course, maximum depth, legal description of property in question and other information the Director of Public Works deems pertinent to the proposed operation.

All requests for renewals of permits hereunder shall be made at least 60 days prior to the expiration date of the permit and must comply with all requirements of § 252-3 above.

§ 252-5 Blasting procedures and controls.

A. 
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 = 0.274 V2 (V = resultant particles velocity expressed in inches per second)
B. 
Measurement of blasts. The operator of the quarry operation, when requested to do so by the Director of Public Works, 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 Director of Public Works, shall measure air blast. This verification shall be performed by a seismological engineering firm acceptable to the City or by the Director of Public Works. Instrumentation shall be by seismograph similar to VME Seismolog Model "B" and approved seismograph sound measuring equipment or approved equivalents. All expenses for these tests shall be paid by the quarry operator.
C. 
Blasting log. A log in duplicate shall be kept of each blast on forms similar to the one on file with 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.
D. 
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.

§ 252-6 Permit fee.

The permit fee for any permit issued pursuant to this chapter shall be as set forth in the City's fee schedule. No permit fee shall be prorated. All permits issued hereunder shall expire on December 31 following the date of issue.
