(Page 2) <br />MINE ID # OR PROSPECTING ID #: M-1977-347 <br />INSPECTION DATE: 6/18/09 INSPECTOR'S INITIALS: ECS <br />OBSERVATIONS <br />This was a routine monitoring inspection for an active 112c limestone quarry permit conducted by Eric Scott of <br />DRMS for the Holcim Slab Canyon site. DRMS met with site operator representative Michael Toelle on site at <br />approximately 1330 and toured the site with him. <br />The required site entrance postings and site boundary markers need to be refreshed and/or replaced as no site <br />entrance sign was present and no boundary markers were observed. <br />Mining at this site has ceased a number of years ago, and the upper portion of the site has been reclaimed and a <br />cell phone tower has been constructed as described in AMO1 and TRO 1. The reclamation of this upper portion <br />of the site is establishing well at this time, and the grasses and evergreen trees on the vegetation "islands" seem <br />to be thriving. <br />Reclamation still needs to take place over the remainder of the site if mining activities are not to resume. It <br />should be noted that the rule state that reclamation should be completed within five years after mining ceases <br />unless the site is put into temporary cessation. Re-grading of remaining areas with steep slopes (including the <br />open pit near the base of the site), spreading of any available soils, and revegetation in accordance with the <br />approved reclamation plan should be undertaken as soon as possible. If changes to the approved reclamation <br />plan need to be made by the operator to more accurately address the current conditions, and facilitate the release <br />of the site, a Technical Revision should be submitted to the Division for review and approval. <br />At a minimum, portions of the site will need to be re-graded to eliminate the steep walls in the disturbed area, <br />and a suitable growth medium will need to be placed over the disturbed areas to support successful revegetation. <br />A weed control plan will likely need to be implemented to keep noxious weeds from becoming established <br />during the early phases of revegetation. <br />I & E Contact Address <br />Michael Toelle <br />Holcim Inc.
