WATER Mr. Louis F. Swift 6101 S. County Road #7 Fort Collins, Colorado 8052 Dear Louis: MANAGEMENT CONSULTANTS -G' SEVEdrEENTH Sr SUITE 3'.0 DEt,.E= C~~LCRaD03.7C2 USa 7E~E-,or,E ~sc~, r- a~os 'ELE==F ~.3]J) 227 ~'-- September 21, 1999 Swift Ponds, Timnath Connell Pit Application, File #iv1-99-065 I received this morning a draft copy of a Maintenance Covenant forwarded to you from Connell Resources. it is understood that the purpose of this agreement is to protect the quantity and quality of the historic use of groundwater. During April of this year, Connell Resources had installed five piezometers around the perimeter of the proposed mining area, and groundwater level data are available for the period April 12 to September 14, 1999. Two of the piezometers (#2 and #4) are located close to Boxelder Ditch and have experienced water level variations of 3.35 and 5.7 feet, respectively. Piezometer #3, located on the eastern boundary of the property and influenced by the Cache La Poudre River water levels, has indicated a maximum water level change of 5.25 feet. However, piezometers #1 and #5, located on the western property boundary' and away from the direct influence of the Boxelder Ditch and the Cache La Poudre River, have experienced maximum water level changes of 1.95 and 1.00 feet, respectively. Following conversations with you, 1 understand that the historic water levels within your ponds have not varied more than 1.0 to 1.3 feet during the last 20 to 25 years. An elevation benchmark has been established at Swift Ponds by Sears-Brown engineers, and I recommend that all elevations in the future should be based on this or other established USGS benchmarks. Within item #2) of the above referenced letter, I would recommend that the following items are also stipulated as part of and included within the agreement. • The monitoring and reporting plan will be developed jointly by the undersigned or their representatives and will include the four new piezometers and those currently existing on the proposed mine area. Connell agrees to monitor all of these piezometers during the total mining period and forward a copy of the results to Mr. Swift on a quarterly basis. • Connell will provide an easement to the piezometers on their property to allow access by Mr. Swift or his representative for validation of the groundwater levels at any time during and following completion of the mining operations.
