Mining
We have received your letter dated March 28, 2007 requesting approval of a substitute
water supply plan for the above referenced plan on behalf of ACA Products, Inc. (ACA). The
request has been reviewed pursuant to 37-92-308(5) and you have paid the required $300 fee.
Notice has been provided to those on the notification list and comments have been received
from Mr. John M. Dingess on behalf of the City of Aurora within the 30-day comment period.
PLAN OPERATION
This proposal is to run a gravel washing operation for 6 weeks beginning in June and
extending through the middle of July. You proposed to divert up to 1 cfs through the Templeton
Ditch off of Halfmoon Creek to fill a sediment pond and to replace water lost through
evaporation and aggregate export. No mining will occur at the site.
DEPLETIONS
You have estimated that the initial fill of the pond will require up to approximately 10 ac-
ft, approximately 2 ac-ft for evaporation, and approximately 0.6 ac-ft for water lost in 20,000
tons of product. The total anticipated depletions are approximately 13 ac-ft. The evaporation
appears to be evenly split for the months of June and July.
REPLACEMENT
ACA has leased a total of 90 ac-ft from Pueblo Board of Water Works. This amount of
water is also intended to replace transit losses and seepage from the pond. This water is
stored in Turquoise, Twin Lakes, Clear Creek, and Pueblo Reservoirs. Pueblo will deliver the
type of water legally appropriate for the intended use and will attempt to deliver water from the
point nearest the intended use to minimize transit loss.
