 (e)  Access to an area possibly subject to flyrock from blasting shall be controlled to protect the public and livestock. Access to the area shall be controlled to prevent the presence of livestock or unauthorized personnel during blasting and until an authorized representative of the person who conducts the surface mining activities has reasonably determined that:

   (1)  Unusual circumstances, such as imminent slides or undetonated charges, do not exist.

   (2)  Access to and travel in or through the area can be safely resumed.

 (f)  Airblasts shall be controlled so that they do not exceed the airblast level specified in this subsection at a dwelling, public building, school, church or commercial or institutional structure, unless the structure is owned by the person who conducts the surface mining activities and is not leased to another person. The lessee may sign a waiver relieving the operator from meeting the airblast limitations of this subsection.

   (1)  [Reserved].

   (1.1)  Maximum decibel level. The maximum allowable airblast level is 133 dBL.

   (1.2)  Exceptions. The Department may specify alternative maximum allowable airblast levels than those in this subsection for use in the vicinity of a specific blasting operation, if necessary.

   (2)  Monitoring. The operator shall conduct periodic monitoring to ensure compliance with the airblast standards. The Department may require an airblast measurement of a blast and may specify the location of the requirements.

 (g)  Blasting requirements are as follows:

   (1)  Blasting operations may not be conducted within 800 feet of a public highway, unless precautionary measures are taken to safeguard the public.

   (2)  When a blast is about to be fired within 200 feet of a pipeline, the operator shall exercise caution as may be needed for the protection of the pipeline. The operator shall notify the owner of the line of the operator’s intention to blast, giving a description of the precautionary measures that will be taken.

   (3)  When blasting is to be done within 1,000 feet of schools or public buildings, it shall be done only during the time approved by the Department. Prior to the blasts, the operator or foreman in charge of the blasting operation shall, within 24 hours prior to the blast, notify persons within this area that a blast is to be detonated. Approval of the method of notification shall be obtained from the Department prior to commencing the blasting.

   (4)  Blasting may not be done within 300 feet of an occupied dwelling or other structure designated by the Department unless prior written consent of the property owner has been obtained.

   (5)  Blasting shall be conducted in a manner to protect the public from flyrock.

   (6)  Notwithstanding other regulations, blasting, whether of overburden or of mineral, may not be done or performed in a manner and under circumstances or conditions that debris is ejected into the air, constituting a hazard or danger or to do harm or damage to persons or property in the area of the blasting.

   (7)  When explosives are being loaded in drill holes in preparation for a shot, work within a radius of 50 feet of the blast area, except for the work being accomplished by the persons engaged in the blasting operation, shall cease, and machinery, other than machinery necessary to the blasting operation, within the confines of this area shall be brought to a complete rest. After inspection of the blast area by the Department, the Department may establish an alternate distance limitation.

   (8)  When a shot is about to be set off or fired, machinery within a radius of 500 feet, or a lesser distance specified by the Department, shall be brought to a complete rest, work shall cease within the confines of this area and workmen shall retreat to a safe location. This paragraph shall apply when the blaster first begins to wire the shot.

 (h)  Blasting shall be conducted to prevent injury to persons, damage to public or private property outside the permit area, adverse impacts on an underground mine, and to protect, to the maximum extent possible, the hydrologic balance.

 (i)  In blasting operations, except as otherwise authorized in this section, the maximum peak particle velocity may not exceed the levels of blasting vibration shown in Figure #1 in §  77.562 at the location of a dwelling, public building, school, church or commercial or institutional building or other structure designated by the Department. The maximum peak particle velocity shall be the largest of three measurements. The Department may reduce the maximum peak particle velocity allowed, if it determines that a lower standard is required because of density of population or land use, age or type of structure, geology or hydrology of the area, frequency of blasts or other factors.

 (j)  The maximum peak particle velocity limitation of subsection (i) does not apply at a structure owned by the permittee.

 (k)  When seismographs are not used to monitor peak particle velocity, the maximum weight of explosives to be detonated within any 8 millisecond period may be determined by the formula W=(d/90)2 where W equals the maximum weight of explosives, in pounds, that can be detonated in any 8 millisecond period, and d equals the distance, in feet, from the blast to the nearest dwelling, school, church, commercial or institutional building. The development of a modified scale-distance factor may be authorized by the Department on receipt of a written request by the operator, supported by seismographic records of blasting at the mine site. If the peak particle velocity will exceed .5 inch per second with the adjusted scale-distance, §  77.562(d) shall be complied with prior to blasting at the adjusted levels.

 (l)  When a seismograph is required to monitor the peak particle velocity, a seismographic record shall be obtained for each blast.

 (m)  The use of a formula to determine maximum weight of explosives per delay for blasting operations at a particular site may be approved by the Department if the peak particle velocity of 2 inches per second required in this section would not be exceeded.

 (n)  The Department may require a seismographic record of blasts and may specify the location at which the measurements are taken.

§ 77.594. Final slopes.

 Final slopes for reclamation of noncoal surface mines shall conform with the following requirements:

   (1)  If there is sufficient overburden material to achieve approximate original contour and no alternative reclamation is approved under §  77.593 (relating to alternatives to contouring):

     (i)   The postmining slopes shall approximate the premining slopes or slopes approved by the Department based on consideration of soil, rock formation, climate or other characteristics of the area.

     (ii)   Final postmining slopes are not required to be uniform but shall approximate the general nature of the premining topography.

   (2)  If terracing is approved for postmining reclamation, the final overall slope shall be 35° or less unless otherwise approved under subparagraph (v).

     (i)   If a water impoundment is part of the reclamation, the slope shall extend to 50 feet (15.2 meters) below the post reclamation water level at a maximum slope of 35° to serve as a safety bench for safe exit from the impoundment. The underwater safety bench may be reduced to a lesser depth—a minimum 25-foot (7.6 meters) width shall be maintained in all cases—if the operator demonstrates to the Department’s satisfaction that there will be an overflow at a defined elevation or that the seasonal water table fluctuation will not require a 50-foot (15.2 meters) depth. For purposes of safe exit from an impoundment in unconsolidated materials, the Department may require an underwater safety bench be sloped at less than 35° from the horizontal.

     (ii)   Benches developed below the lower level of the reclamation safety bench are not required to be restored.

     (iii)   Removal of benches below the safety bench requires approval from the Department in writing under §  77.573 (relating to stability analysis).

     (iv)   The Department may require a slope of less than 35° if stability concerns require a lesser slope.

     (v)   A slope greater than 35° may be approved if the operator demonstrates that the slope will not result in a safety or stability hazard and that one of the following exists:

       (A)   No practical alternative to a lesser slope exists, such as unusual geologic conditions.

       (B)   The slope area which is greater than 35° is offset by a lesser slope elsewhere at the site resulting in a more beneficial postmining land use as approved by the Department.
