The activity involves installation of support piers and box culverts for four (4) ditch crossings and the St. Vrain Creek bridge while the water is low in the winter. No mining activity of any kind will take place at this time (i.e., no topsoil stripping, overburden removal, limestone mining, blasting, crushing, transportation of production rock, etc.). The haul road will be a permanent feature, used as access to the property after mining and reclamation. The existing permit includes no provisions for demolition or reclamation of the haul road because it will remain in place as permanent access to the property. Southdown wishes to comply with the conditions of Permit No. M-93-041 for this initial phase of the project. The permit conditions and our response to them follows: No. 1: Cultural Resource Management Plan (CRMP) A draft CRMP has been reviewed by the State Historic Preservation Office (SHPO). SHPO made some minor comments and the final draft will be submitted in November, 1994. We are meeting with SHPO on Thursday, November 17, 1994. We will ask SHPO to write a letter to the Division stating they have no objections to the preliminary construction. No archaeologic sites are present in the vicinity of the preliminary construction nor are any predicted to be found in the subsurface. Minimal excavation will take place in the preliminary construction phase. The ditches have some historic significance and the areas of the crossings have already been photodocumented (as recommended in the CRMP). No. 2: Black Footed Ferret Studv The study has been completed and no ferrets were found. A letter from the project wildlife biologist (Rick Thompson) reporting the findings has been previously forwarded to the Division. The final report will be submitted later this month.
