Seed following overburden and topsoil distribution, once a sizeable <br />area of two to three acres is ready for seed. Seeding timetable is <br />estimated at two year intervals <br />(F) (i). Mining depth is expected to be less than 15'. All mined material can be sold. <br />The estimated 0-12" of overburden will be stripped and stockpiled with the <br />topsoil. If groundwater is encountered, mining depth will be adjusted to <br />stay above ground water levels. <br />(ii) Stratum immediately below the mined area is the same as the mining <br />strata. <br />(G) The primary commodity to be mined is sand and gravel. No secondary products <br />are generated. All rock removed from the pit wall is marketable as sand and gravel in <br />various shapes and sizes. No waste piles will be generated. The extracted material will <br />be used in construction activities including concrete and asphalt aggregates. <br />(H) No incidental products will be generated. <br />(1) No blasting will be needed in conjunction with the mining or reclamation. <br />NOXIOUS WEED CONTROL PLAN: <br />Russian knapweed will be burned in the spring. It will be sprayed using Curtail at a rate <br />of 4 quarts to an Acre at flower stage on regrowth. It will be sprayed again using Curtail <br />at the same application rate prior to first hard frost in the fall. <br />Areas within the permit boundaries will be monitored each Spring, Summer & Fall. <br />Weed treatment will only be performed on areas infested with Russian knapweed inside <br />the permit boundaries. <br />All equipment and haul trucks will be inspected prior to leaving the site. If contaminated <br />materials are found, the contaminated material will be removed from equipment or haul <br />trucks prior to exiting the site. <br />Asphalt Constructors, Inc. will enlist the aid of the Rio Grande County Weed Director on <br />seasonal inspections to help identify any noxious weeds within permit boundaries. <br />If any noxious weeds are found within permit boundaries, a weed control plan specific to <br />the weed will be developed with the Director and implemented.
