management have been incorporated into each facility's Mined Land Reclamation Permit. These requirements
include specific requirements for protection of groundwater as described in Rule 3.1.7(7)(1) through (viii) of the

Holcim submitted a request for a Technical Revision (TR-06) to its permit on August 16, 1999 for the disposal

disposal procedures and facilities, a closure plan for the disposal areas, a description of erosion control measures
used at the site, a discussion of CKD sampling and analysis, and a description of hydrogeologic conditions at the
site. The DMG reviewed TR-06 and responded with an initial adequacy review letter on January 18, 2000
(DMG, 2000). On behalf of Holcim, K-S & Company submitted responses to DMG's adequacy review letter in
May 2001 (Holnam, 2001). The DMG responded with a second adequacy review letter on October 22, 2002
(DMG, 2002). This GMP will partially fulfill requirements from DMG's first and second adequacy reviews.
