We are continuing to work in Phase lA as shown of the map, listed as Exhibit C-2. The sand processing plant remains as previous on top of deposits yet to be mined. The crusher remains at the site indicated. Permanent wetlands have been reclaimed from areas in Phase lA and Phase 1C as indicated upon completion of mining. Permanent wetlands are continuing to be developed in the southwest portion of Phase IA. We anticipate mining a portion of Phase 1B from south to north during 2005. Backfill in this area will depend on mining progress. All wetlands, whether permanent or temporary, have been topsoiled and reseeded as reclamation progressed. Some willow trees, juniper trees, and sumac have been planted depending upon applicable hydrologic regions. Additional plantings will be installed in the Spring of 2005. Groundwater monitoring wells are in place up gradient of the property as shown on the attached map, Exhibit C-3. Quarterly reports are attached, Exhibit C-4, for the yeazs 2002, 2003, and 2004. Note that the groundwater elevations for the first quarter of 2004 are abnormally low due to adjacent mining and pumping in Phase IC. Ground water levels rapidly recovered by the second quarter of 2004 upon cessation of pumping and completion on backfilling in Phase 1C. Sincerely, ~,,,_aG~~-- Dan Kehn Attachments 6550 So.
