Township:
New
Revised
Module’s 28.1 through 28.7 must be submitted with the permit application. Module’s 28.8 through 28.12 must be
submitted prior to blast plan approval. There shall be no blasting until a blast plan has been approved by the

28.1
Underground Mines
Any coal mining activities that will include blasting within 500 feet of an active underground mine must be
jointly approved by the Department and the Mine Safety and Health Administration (MHSA). Any coal mining
activities that will include blasting within 500 feet of an abandoned underground mine must be approved by
the Department.

Will blasting occur within 500 feet to any point over or adjacent to an active or abandoned portion of an
active underground mine.
Yes
No
If yes, submit four (4) copies of form "Surface Mining near Underground Mines – MHSA Coordination"
(5600-PM-MR0026) along with the permit application to the Department. The Department will forward
the information to MSHA.
28.2
Streams

If blasting will occur within 100 feet of a stream, identify the stream and indicate the distance that
blasting will occur from the stream.

If yes, attach a copy of the notification sent to the owner that describes any precautionary measures
that will be taken.
(Note: when blasting within 200 feet of buried or underground utility line or line making contact with the
surface of the ground the provisions of 25 Pa. Code Section 211.182 apply. The Department considers
limiting ground vibration to 2.0 in/sec or less or designing blasts to a scaled distance of 50 or greater
acceptable to meet the requirements of Section 211.182(a) to “keep the resulting vibration and actual
ground movement to the lowest level possible.”)

Peak Particle Velocity and Airblast Limits
Blasts shall be designed and conducted to achieve either a minimum scaled distance of 90 or meet the
maximum allowable peak particle velocity indicated by Figure 1 of 25 PA Code Chapter 211.151 (c) and not
exceed the noise levels specified in Table 1 of 25 PA Code Chapter 211.151 (d) at the closest building not
owned or leased by the permittee or its customer.
The Department may establish an alternative peak particle velocity or airblast level if it determines that an
alternative standard is appropriate or if the owner and lessee, if leased to another party, of a structure located
on the permit area have each signed a waiver releasing the vibration limit. The waiver shall be clear, knowing
and specific.
a.
Is the permittee requesting an alternative peak particle velocity or airblast level?
Yes
No
If yes, provide the documentation requested in the instructions forementioned section.
NOTE: Alternative peak particle velocity or airblast levels are only available at buildings located on the
surface mine permit. Additional review time will be necessary if the applicant submits a waiver for an
alternative peak particle or airblast limit at a structure.

Blasting near Dwellings, Public Buildings or Schools
a.
Will blasting occur within 1,000 feet of any dwelling, public building or school?
Yes
No
(Note: If blasting will occur within 1,000 feet of a public building or school, a notification that was
approved by the Department, is required 24 hours prior to the blast.)
b.
c.
28.7
If blasting will occur within 1,000 feet of any dwelling, public building or school, provide the following
information:
i.
A description of the proposed method of notification and how notification required by 25 Pa Code
Section 87.127(f)(3) will be made.
ii.
The distance to the nearest dwelling or structure, neither owned nor leased by Permittee, from
the area where blasting will occur.
(feet)
If blasting is proposed within 300 feet of an occupied dwelling, provide a notarized written waiver from
the owner of the dwelling specifying the distance blasting may occur to the dwelling. (Note: If the
waiver includes an increase in the peak particle velocity limits or in the airblast limits, 25 Pa Code
Section 87.127 specifies that the alternative limits must be specified in the waiver).
