Hal D. Simpson, P.E.
State Engineer
We have reviewed your letters of July 2, 2004 and June 22, 2005 requesting approval of
the substitute water su I Ian for the above referenced gravel pit (well permit no. 48758-F).
The required $217 ees have been paid.
OPERATION
The mining operation is a dry operation. Water uses at the pit include surface water
evaporation and moisture retained in product. Mining operations began in 1975 and have
exposed a water surface area of approximately 4.3 acres. Out of the 4.3 acres of maximum
groundwater exposure that will occur during this plan, 2 acres were exposed prior to January 1,
1981.
DEPLETIONS
The maximum estimated depletions to be covered total 9.285 acre-feet annually,
consisting of 9.225 acre-feet of net evaporation off of 2.3 acres of post-1980 ground water
exposure, and 0.06 acre-feet of water lost with 2,000 tons of mined product (4% loss by product
weight). A monthly breakdown of these amounts and their lagged affects on the Arkansas River
is given on the attached table. No pumping occurs for gravel washing, dust suppression, or
concrete botching purposes.
REPLACEMENT
The source of replacement water to cover the plan's depletions is again from Lower
Arkansas Water Management Association (LAWMA). LAWMA will provide 9.3 acre-feet of
replacement water, and in return Bent County Ready Mix will assign to LAWMA the use of 12
shares of Fort Bent Ditch Company stock. Currently Bent County Ready Mix is working with
LAWMA to update the agreement for replacement water for this plan.
