[Amended 2-12-2020 by L.L. No. 3-2020]
The purpose of this chapter is to establish minimum safeguards
to protect human health, safety and welfare, as well as property,
by establishing reasonable regulations governing the possession and
use of explosive materials. To ensure that the possession and use
of explosive materials does not result in physical injury or property
damage, the Town Board hereby asserts its right to designate acceptable
hours for blasting operations, set levels for the ignition and discharge
of explosive materials and establish acceptable standards governing
consequential vibrations resulting from all blasting conducted within
the Town.

A. Inspection. Because of the compelling and overriding public safety
issues involved in the handling and use of explosives, the Building
Inspector, Town Engineer, Fire Marshal, Code Enforcement Officer or
any member of the Police Department may inspect any vehicle, structure,
dwelling, construction site, workplace or other area where explosives
are manufactured, sold, possessed, stored or used within the Town
for the limited purpose of ascertaining and verifying compliance with
this chapter.
B. Permit revocation. The Building Inspector may, on her/his own initiative
or at the request of any other official, revoke or modify a permit
issued pursuant to this chapter where it appears the permit holder
has violated any local, state or federal rule or regulation, including
but not limited to a false statement or representation on the application
for a blasting permit or violation of any applicable safety standard
or where the Building Inspector determines that public safety has
been compromised. The Building Inspector may modify or revoke a permit
by notifying the permit holder or her/his representative, orally or
in writing, that the permit has been modified or revoked. Where a
permit has been revoked, the Building Inspector shall send a written
notice of revocation to the permit holder by first class mail without
unnecessary delay, but not later than five business days after revocation,
setting forth the reasons the permit was revoked. The notice of revocation
shall include a statement informing the permit holder of her/his right
to appeal such revocation by filing a notice of appeal with the Town
Clerk within 20 business days. Where a permit is modified, the Building
Inspector shall give the permit holder written notice of the modifications.
C. Appeals. A permit holder who has had her/his permit revoked or modified
by the Building Inspector may appeal and seek relief from the modifications
or reinstatement of the permit. An appeal pursuant to this section
shall be heard by the Chief of Police, the Town Engineer and the Fire
Marshal, or any of their deputies, sitting as a board of appeals.
The Building Inspector shall appear and state her/his findings and
the reasons for revoking or modifying the permit. The permit holder
and/or the blaster shall be offered the opportunity to appear and
present evidence why the permit should not be modified or revoked.
The appeal board may sustain the Building Inspector's decision
to revoke a permit, reinstate any permit or amend any modifications
imposed by the Building Inspector. Where the board reinstates a permit,
the board may amend the permit by adding whatever terms and conditions
it deems necessary to protect public health, safety and welfare. The
decision of the appeal panel shall be final.
[Amended 2-12-2020 by L.L. No. 3-2020]
Blasting may be conducted
when authorized by permit Monday through Friday between the hours
of 8:30 a.m. and 3:00 p.m. Blasting is prohibited Saturdays, Sundays
and legal holidays, unless modified by an approving Board.
[Amended 2-12-2020 by L.L. No. 3-2020]
A. If the applicant (or successor in interest) intends to remove rock
by means other than blasting, a High Resolution Seismic Refraction
Survey must be performed. A licensed, certified, geotechnical engineer
shall interpret the results of the survey and will determine whether
or not all of the rock can be removed by means other than blasting.
The geotechnical engineer will submit a written report on the site
to the Building Department.
B. If the report reveals that all of the rock cannot be removed by means
other than blasting, then no removal of overburden shall take place
with the exception of tree stumps, top soil or materials rendered
inconsequential by the blaster.
C. If the report reveals that all of the rock can be safely chipped,
a temporary, solid barrier no less than eight feet, zero inches high
shall be installed for the duration of the rock chipping activities,
to the satisfaction of, and if required by, the Building Inspector.
D. The applicant (or successor in interest) shall be limited to the
hours of 8:30 a.m. to 3:00 p.m., Monday through Friday, for all rock
chipping. Rock chipping is prohibited on Saturdays, Sundays and all
legal holidays, unless modified by an approving Board.
E. The applicant (or successor in interest) shall conduct a precondition/preconstruction
survey of all adjacent structures located within 50 feet of the limits
of disturbance on the subject property or any other structure that
the Building Inspector deems necessary in order to ensure public safety
or prevent property damage. The survey shall be submitted to the Building
Inspector or her/his designee for review.
F. The applicant (or successor in interest) shall install seismic graphs,
set in histogram mode, on the property, outside the area of rock removal,
that are to be monitored once an hour to ensure the vibrations from
the site do not cause damage to adjacent structures of the property.
The number of seismic graphs shall be determined by the geotechnical
engineer and agreed to by the Building Inspector, or her/his designee.
A daily report of the seismic graph readings must be submitted to
the Building Inspector. The report shall use the USBM Vibration limit
curve developed from RI8507. Should a seismic reading exceed the Town
of Greenburgh's limitations, the work must cease immediately,
and written notification must be provided to the Building Inspector.
G. Prior to any rock chipping activities, appropriate dust control measures
must be installed to the satisfaction of the Building Inspector.
H. The maximum decibel level for rock chipping activities must not exceed
110db(A), as measured from any property line.
I. All rock chipping must be completed within 30 business days of commencement
of such activities. Thereafter, the applicant (or successor in interest)
must cease such activities and seek additional approval from the Town
Board or Planning Board to resume rock chipping activities.
[Amended 2-12-2020 by L.L. No. 3-2020]
Any person applying to
use explosives to demolish any structure must agree to assume the
cost of any engineering analysis, public safety survey, environmental
review or other technical study deemed necessary by the Building Inspector
to determine if and how blasting or rock chipping can be conducted
safely.
[Amended 2-12-2020 by L.L. No. 3-2020]
The Police Chief, Town Engineer and Building
Inspector/Fire Marshal, sitting as a Board of Standards, may supplement

and welfare. A copy of all supplemental rules and regulations promulgated
under this section are to be provided with each application for a
permit and posted on the Town's Web site.
