REcev FD FEe 1 2 20 19 Greg Lewicki And Associates, PLLC 3375 W. 1'mici-, Circle Phone: (720)8.12-5321 1,ax (303)346-6934 Littleton,( 0 80123 L-mail: info a levvicki.bir February 11, 2019 Stephanie Mitchell Colorado Department of Natural Resources Division of Reclamation, Mining and Safety 1313 Sherman Street, Room 215 Denver, CO 80203 RE: King Pit,File No. M-1987-012, 112 Amendment (AM02)Bond Recalculation Stephanie: As discussed via phone and email on November 19, 2018, see the attached `King bond re- calculation 181114.xls' print-out with regard to changes to the King Pit AM-02 bond calculation. I apologize for not submitting the request in formal writing back in November. I've detailed the changes preferred and where to find the corresponding information in the AM- 02 submitted permit file. Also, Lucas West prepared a bond calculation for the Garrett Pit over the summer and the same reclamation plan was designed for the King Pit. Maybe his files could serve as comparison as much of the information and design is the same. Major change requests are as follows: • change floor rip to 60 acres (from 150) • remove crusher fines spread across the site (they will be mixed into overburden, as available/needed) • topsoil replacement should be for 50 CY(reflects 60 acres; not 80 CY) • change revegetation throughout to 60 acres (from 100) • change 3 ton/acre hay to 1 ton/acre straw • remove power mulcher • change weed spray to truck application (from hand spray) • remove double fertilizer application if revegetation is unsuccessful • the seed mix in the current calculation does not match that listed on page E-5 of the amendment file. Lastly, could you please confirm the timeline for bond payments with respect to conditional versus full approval by the DRMS? Resolution with the BLM is continuing to stretch on and we want to be aware of exactly how this hold up could affect our application.
