    Genwal Resources, Inc., P.O. Box 1077, Price, Utah 84501 has filed 
a petition to modify the application of 30 CFR 75.901 (Protection of 
low- and medium-voltage three-phase circuits used underground) to its 
South Crandall Canyon Mine (MSHA I.D. No. 42-02356) located in Emery 
County, Utah. The petitioner requests a modification of the existing 
standard to permit an alternative method of compliance for the 
grounding of a diesel generator. The petitioner proposes to use a 
portable diesel generator for utility power and to move electrically 
powered mobile and stationary equipment throughout the mine. The 
petitioner asserts that the proposed alternative method would provide 
at least the same measure of protection as the existing standard.

required in 30 CFR 75.900 for short circuit protection only. The 
contactor will be equipped to provide under-voltage, grounded phase 
protection, and other protective functions normally provided by the 
contactor. The petitioner has listed specific terms and conditions in 
this petition for modification that will be followed when the proposed 
alternative method is implemented. The petitioner asserts that the
