Re: Renewal Request for Consolidated Substitute Water Supply Plan (SWSP) for Valco, Inc.,
Pursuant to 37- 90- 137(11) in Water Division No. 2.
Dear Heidi:

We are writing to request a renewal of a consolidated Substitute Water Supply Plan (SWSP) on behalf of
our client Valco, Inc. (Valco) for their aggregate operations in the Arkansas River basin (Water Division
2). Valco has stopped or is in the process of stopping gravel mining operations at the three pits included
in this SWSP renewal request and is preparing to sell the pits. If a sale is not possible at this time, Valco
will need to include the pits in a permanent augmentation plan. Because these processes can takes some
time, Valco requests an SWSP renewal during this transition phase for a two year period from June 1,
2011 through May 31, 2013 (SWSP renewal period).
Background
Valco operates the following aggregate pits in the Arkansas River basin:
1. Canon City East Pit, located in Sec.1, T19S, R7OW (DMG Permit No. M -77 -559)
2. Rocky Ford East Pit, located in Sec.21, T23S, R56W (DMG Permit No. M -77 -560)
3. Lamar East Pit, located in Sec.29, T22S, R46W (DMG Permit No. M -77 -572)
In addition, two alluvial water wells which provide water for batch plant uses under Well Permit Nos.
22830 -F and 10525 -F are located at the Canon City East Pit and the Rocky Ford East Pit, respectively.
The three mining sites along with the two alluvial water wells have operated under a consolidated SWSP
for several years. The most recent SWSP renewal request was approved September 24, 2009 for
operations from June 1, 2009 through May 31, 2011.
Review of June 2009 through May 2011 Operations
From June 2009 through May 2011, all operational and evaporative depletions were fully replaced. The
depletions . included all aggregate operational depletions and evaporation depletions due to exposed
ground water surface areas. The total exposed water surfar.e was redlined to reflect pre -1981 exposed
water surface credits pursuant to SB 89 -120. We believe that all of the 2009 SWSP terms and conditions
of approval have been met to the satisfaction of the Division Office.
