or in conjunction with any other device, machine, apparatus or equipment
for the purpose of crushing, grinding, breaking or pulverizing rock
or stone.
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.

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 f2A2
|
|
Where:
| ||||
|---|---|---|---|---|
|
f
|
=
|
frequency in cycles per second
| ||
|
A
|
=
|
amplitude or displacement in inches
| ||
|
Energy ratio = 0.274 V2
|
|
Where:
| ||||
|---|---|---|---|---|
|
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 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 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-Treasurer. The original
copy of this blasting log shall be filed with the City Clerk-Treasurer
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.
The permit fee for any permit issued pursuant to this chapter
shall be as set by resolution of the Common Council. No permit fee
shall be prorated. All permits issued hereunder shall expire on December
