HomeMy WebLinkAbout20111758 11 EVIDENCE OF ADEQUATE WATER SUPPLY
Lafarge's Lease Agreement with the Iversons requires the Iversons to provide the water needed to
operate the Iverson Mine Site. The Iversons have 6 'A shares of Greeley Irrigation Company water
that will be used on site for dewatering, washing the material and dust control. Lafarge will provide
bottled water to the employees working at the mine to meet potable water needs. There will be no
office building, all employees on site will be working on the mine face; therefore, portable toilets
with a portable handwashing facility will be provided for use by the employees. Therefore, this site
will not require a well or a connection to a potable water system to meet water supply needs.
Attached is a copy of the Iversons' stock certificate for their 6 'A shares of the Greeley Irrigation
Company water along with a letter from Tim Iverson confirming that it will be used to meet the
operational needs at the Iverson Mine site.

RE: Water Supply and Augmentation for Lafarge West, Inc.'s Iverson Mine Site
Dear Corey:
Consistent with the Lease Agreement that my wife, Jeanne, and I have with Lafarge
West, Inc. ("Lafarge") for the mining of our property located in Section 34, Township 6
North, Range 66 West of the 6th PM, Weld County, Colorado, we will allow Lafarge to
use the 61/4 shares of the Greeley Irrigation Company water that we own. We
understand that this water will be used to meet the operational needs of the Iverson
Mine. In addition, we acknowledge that all augmentation requirements both during
mining and in perpetuity, once the site is reclaimed are our responsibility. We are in the
process of working out the details related to how we will satisfy all augmentation
requirements and we will provide Lafarge with additional information regarding this
matter as soon as possible.
Sincerely,
Tim Iverson
EVIDENCE OF ADEQUATE SEWAGE DISPOSAL
There will be no office facility located on this property; therefore, Lafarge will have portable
restrooms available near the working face of the mine for use by the employees. Lafarge
understands that the portable toilets will not be allowed in the floodway and will only be permitted
in the flood fringe if they are anchored and permitted through a Weld County Flood Hazard
Development Permit.
