The annual operational loss is estimated at 5.4 acre-feet. The moisture content of the material transported off the site was assumed to be 4 percent by weight. The annual amount of mined product for the pit is estimated at 150,000 tons. This results in 4.4 acre-feet of water retained in the amount of product mined annually. Dust control is required for internal haul roads and stockpiles. To manage dust, a 2,000-gallon water truck is assumed to spray its entire load three days a week throughout the yeaz. This results in a consumptive use for dust control of 1.0 acre- foot per yeaz. The estimated maximum annual consumptive use associated with the mining operation is summarized as follows: Consum tive Use Annual Water Loss (acre-ft Eva ration 10.3 Moisture Retained in Product 4.4 Dust Control 1.0 Total 15.7 Sources of Water In order to replace out-of-priority depletions, Western Equipment and Truck, Inc. will submit a substitute water supply plan to the State Engineers Office. Western Equipment and Truck, Inc. owns water rights in the Greeley Loveland Irrigation Company (GLIC). The GLIC system has three companies that provide water that include the Lake Loveland, Seven Lakes, and Greeley Loveland direct shares. These water rights will be used in the substitute supply plan for replacement of depletions associated with the mining operation An existing pond on the property owned by Westem Equipment and Truck, Inc. will be used as a recharge site for augmentation. A rechazge program uses a dvect ditch water right to create winter augmentation water in each month of the year. A portion of the GLIC water rights owned by Western Equipment and Truck, Inc. will be diverted into the recharge lake from May through September during the irrigation season. This ditch water is allowed to infiltrate into the groundwater and alluvium. The "recharged" ditch water moves back to the Big Thompson River along the hydrologic gradient and is lagged in such a way that it arrives at the river months after the ditch water was initially rechazged into the lake. The lagged effect of the recharged irrigation water rights will allow the GLIC shares to be used for augmentation of mining depletions throughout the year. Westem Equipment and Truck, Inc.'s owns sufficient GLIC water rights to make replacement for depletions through the life of the mining project. No groundwater will be exposed by the mining operation until the State Engineers Office approves the substitute water supply plan. Surroundine Water Rights As required by the State Engineers Office, a substitute water supply plan and a gravel pit well permit will be obtained for the consumptive use from the mining operation. The required 600- foot well inspection was completed with District 4 Water Commissioner, Fred Renner on May 22, 2002. No registered or unregistered wells were located within 600 feet of the future pit boundary of the Two Rivers Mine that would require notification by the State Engineers Office.
