These piles would also be seeded and <br />sediment control provided. <br />When the rock has been exposed, MCC will remove any loose materials first and if <br />need be, employ a drilling and blasting contractor to break the rock into sizes that are <br />specified for the buttress fill. The selected contractor will comply with all Federal and <br />State rules pertaining to blasting, including surface blaster certifications and clearing all <br />mine and contractor personnel prior to blasting. <br />As the soil storage areas are on existing disturbed areas and the two rock quarry sites <br />are less than two acres each and are near or at the ridge top, small area exemptions <br />are requested so that alternative sediment control measures, including silt fences and <br />straw wattles, can be utilized to control runoff from the sites. Following removal of all <br />the rock needed, the sites will be recontoured with the stockpiled subsoil to blend with <br />the surrounding areas, then vegetative soil material distributed over the surface and <br />seeded with MCC's permanent reclamation seed mix. <br />The loose and broken rock will be loaded by trackhoes and /or loaders into 10 -ton <br />tandem trucks equipped with rock beds and transported to the RPEE buttress. The <br />material will be dumped at the buttress and then placed with one or more trackhoes. <br />The rock quarrying project is scheduled to begin on or near May 27 and is expected to <br />take approximately two weeks. Hauling and placing the rock and placing on the rock <br />buttress is projected to last into mid - August. <br />Please contact me at (970) 929 -2238 or by e-mail should you have questions regarding this <br />submittal. <br />Sincerely, <br />Kathleen G.
