Ruling and Decree <br /> Case No.2009CW271 <br /> City of Longmont <br /> Substitute Water Supply Plans for Sand and Gravel Pits and § 37-92-305(12)(a), C.R.S. <br /> ii. Depletion rate per acre- Wetlands. The net per acre rate of <br /> increased depletions attributable to new wetlands area established by the Project shall be <br /> determined based on the location of the wetlands within one of four zones located within the <br /> Mine Permit Area as shown on the attached Exhibit E, and ranges from 2.302 to 2.615 acre-feet <br /> per acre annually. Table 4 shows the monthly per acre augmentation replacement requirements <br /> for increased depletions of water by new wetlands within the reclaimed Mine Permit Area. <br /> Table 4 <br /> Acre-Foot per Acre Replacement Requirements <br /> Water Zone 1 Zone 2 Zone 3 Zone 4 <br /> Surface New New New New <br /> Month Evap.

Determination of area. Longmont shall survey the(post December <br /> 31, 1980)free water surface area established by reclamation of the Mine Permit Area and shall <br /> bi-annually survey the total post-mining area of new wetlands. For purposes of this Ruling and <br /> Decree, "wetlands" shall be defined in accordance with the criteria contained in the U.S. Army <br /> Corps of Engineers Wetlands Delineation Manual (USACE 1987), as it may be amended or <br /> updated at the time of such survey. The surveyed acreage shall be recorded on Longmont's <br /> accounting forms. Bi-annual wetlands area surveys of the Mine Permit Area shall continue after <br /> mining ceases until the percentage change from the prior survey is less than 5%. <br /> iv. Calculation of total depletions. Longmont's total depletions for the <br /> Project Reclamation Features shall be calculated by multiplying the surveyed water surface and <br /> wetlands area acreages by the per-acre unit depletion rates in Table 4, which shall be converted <br /> 14 <br />
