[HISTORY: Adopted by the Town Board o f the
Town of Greenburgh 2-8-1995 by L.L. No. 2-1995. Amendments noted where
applicable.]
[Amended 2-12-2020 by L.L. No. 3-2020[1]]
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.
[1]
Editor's Note: This ordinance also changed the title of this
chapter from "Explosives and Blasting" to "Explosives, Blasting and
Rock Chipping."
A.
This chapter shall apply to each and every person,
corporation and business engaged in the manufacture, sale, transportation,
storage, handling or use of explosives in the Town. This chapter sets
forth procedures for the issuance of permits, payment of fees, recordkeeping,
reporting and monitoring compliance. In addition, this chapter establishes
penalties for the failure to comply with these requirements.
B.
The technical standards set forth in this chapter
are based upon generally recognized criteria and accepted industry
standards. See New York State Labor Law, Article 16; 12 NYCRR Part
39; NFPA No. 495-1973; 27 CFR 55; 49 CFR 171 through 178; and 49 CFR
390 through 397 for other additional standards that may be applicable.

The applicant shall be responsible for any costs incurred
by the Town in providing police, emergency services or any other personnel
deemed necessary to ensure public safety.
I.
Notwithstanding any other regulations, no blasting
shall be performed in such manner or under such circumstances as to
eject debris into the air so as to constitute a hazard or danger or
do harm or damage to persons or property. Before firing a blast which
could cause injury to persons or damage property from fly rock, the
material to be blasted shall be properly covered or screened by a
buffer of sufficient mass and strength to prevent, with a margin of
safety, the ejection of any material capable of causing any injury
or damage.
J.
No person shall use a quantity of explosives greater
than necessary to break or move the target material or use an amount
of explosives that poses a risk of injury to persons or property.
K.
Unless otherwise permitted by
the Building Inspector, all holes drilled or otherwise excavated for
holding an explosive charge shall be at least six feet deep. If, however,
the permit holder/blaster can demonstrate a need to use a hole less
than six feet deep and that such a cavity will not endanger public
safety, the Building Inspector or her/his designated representative
may, in her/his discretion, authorize the use of blast holes less
than six feet deep.
L.
The blaster shall plan each blast and take every precaution
in loading, delaying, initiation, confinement and stemming to control
the throw of rock fragments and debris and limit ground vibrations
and the effect of air concussions to the greatest extent possible.
When blasting is to be conducted within 50 feet or less of a property
line and the adjacent property owner is not a party to the blasting
operation, the blaster shall take all precautions practicable, utilizing
any combination of recognized methods, to control blasting effects
to the greatest degree possible.
M.
A record of each blast shall be
kept by the blaster on a form approved by the Building Inspector.
All such records shall be retained by the permit holder and blaster
as prescribed by state law and made available for inspection as a
matter of public record.

at a flat frequency response (PMS two decibels) over the range of
at least six to 200 hertz.
B.
When blasting is of a continuing nature, 124 to 130
decibels shall be the acceptable range.
C.
The permit holder shall report each blast exceeding
acceptable parameters to the Building Inspector within 24 hours. Following
a blast exceeding acceptable parameters, the Building Inspector shall
have the authority to order blasting operations to be suspended, altered
or stopped.
D.
The US Bureau of Mines Safe Vibration Criteria, with an upper allowable
limit of 1.25PPV will be the governing standard. Charts plotting both
the Peak Particle Velocity (in/s) and Peak Frequency (Hz) must be
provided after each and every blast.[1]

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.
A.
Not more than 20 calendar days
and not less than three business days prior to a scheduled blast,
the permit holder shall serve a notice of intent to blast, stating
when and where blasting activity is scheduled to occur, on each occupant
or user of each structure, commercial or residential, within 500 feet
of the proposed blast site and upon the owner or owners of any parcel
of property immediately adjoining or abutting the parcel of property
on which the blasting is to take place, regardless of the distance
an adjoining owner is from the blast site. The notice shall include
the blasting permit number, the permit holder's name, emergency
telephone numbers for police, fire and ambulance service and the time
and location of each scheduled blast. A copy of the notice of intent
to blast must be submitted to the Building Inspector for her/his review
and approval prior to distribution.
[Amended 2-12-2020 by L.L. No. 3-2020]
B.
The notice of intent to blast may be served by either
personal service or certified mail. In the event that neither personal
service nor certified mail can be effected, the applicant may request
authorization from the Building Inspector to serve the notice of intent
to blast by posting a copy of such notice in each building or dwelling
in a conspicuous place where it is reasonable to believe that persons
entering or leaving the premises will see such notification.
C.
In the case of multi-occupancy
structures, residential and commercial, located within 500 feet of
the blast site, the notice of intent to blast shall be conspicuously
and continuously posted at all commonly used entrances to the structure
not more than 20 calendar days and not less than three business days
prior to blasting. It shall be the blaster's responsibility to
ensure that notice is unobstructed and remains posted at the structure.

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.
