It does get complicated as we are talking about the site, water <br />volumes, and sediment <br />Thanks <br />Gary <br />From: Cazier, Tim Jmailto:Tim.Cazier©state.co.us] <br />Sent: Monday, January 09, 2012 3:53 PM <br />To: Gary Tuttle <br />Subject: RE: M -1986 -015 Pueblo East Pit, AM -04 Pumping Cost <br />Thanks Gary. Unless I've missed something, it's not a rush. I'll likely use an excavator or dragline in conjunction with <br />haul trucks, as that is likely the way the Division would bid the job if that's what it came to for reclamation. However, if <br />I did miss something and there is a benefit to pumping, by all means, please let me know. <br />Tim Cazier, P.E. <br />Environmental Protection Specialist <br />Colorado Division of Reclamation, Mining and Safety <br />1313 Sherman Street.
