EXHIBIT G WATER INFORMATION There is one well on the site. It is a commercial well rated for 300 gpm is owned by The Walsenburg Sand and Gravel Co. . The dry stream bed of Sand Arroyo bisects the site from southeast to west . The new areas being added are outside this channel and will not impact groundwater or affect surface waters unless mined. The following information was reproduced from the 2002 application packet and information was added as appropriate for the new area being added. (1) Since this is strictly a dry pit operation, no surface or groundwater shall be required for evaporation loss replacement water. (2) Since this operation will not affect surface or groundwater systems, items (a) (b) and (c) are not necessary for this application. However, the following information is being submitted as a matter of course to verify this position. (a) The map shows that Sand Creek is the main part of this permit acreage and the only water course . Neither are there any springs or reservoirs on the affected lands or adjacent lands . The Walsenburg Sand and Gravel Co. has a well on site that supplies water to the Batch Plant for minor dust control . It is covered by Permit #12262F Water case #W0464 and is shown on the Map Exhibits . (b) There are no known aquifers to be identified. (c) There will be no dewatering operation involved in this operation. Sand Arroyo will continue to flow through the area as it has done historically. A Stormwater Discharge Permit and associated Stormwater Management Plan (SWMP) have been developed for the operation. (3) There will be no water requirements as stated previously for the development, mining and reclamation phases of this opera- tion. (4) The applicant does not need a U.S . Army Corps of Engineers 404 Permit to mine within in the dry creek bed. A letter from the Corps of Engineers has confirmed the lack of necessity for said permit . (Copy follows) 23 (REVISED 3/6/2020)
