Re: Northern Colorado Constructors, Inc. (NCCI) Pit No. 1 Substitute Water Supply Plan
Dear Ken:
The purpose of this letter is to inform you of the current status of the above referenced project. We have
completed a majority of the substitute water supply plan (SWSP), with the exception than we have not yet
determined or established a replacement water supply. The estimated annual mining depletions resulting
from the mining operations at NCCI Pit No. 1 will initially be about 14.27 acre-feet per year. NCCI
purchased three (3) shares of Lupton Meadows Ditch (Cert. No. 0632) that were historically used at the
mining site. The historical return flow obligation associated with this water rs estimated [o be 2.86 acre-
feet per year and the estimated farm headgate delivery is estimated to be 6.33 acre-feet per year.
Therefore, the net result of mining operations and use of three shares of Lupton Meadows Ditch for
replacement is a deficit of 10.80 acre-feet per year (see Table 6 for calculations).
M additional 10 shares of Lupton Meadows Ditch (Cert. No. 0646) were purchased by NCCI for
purposes of providing replacement water for the mining operations at Pit No. l . Unfortunately, we have
been unable to identify that lands where these 10 shares were historically applied. We believe that in
order for the State to accept this water as a replacement source for the substitute water supply plan, we
must identify the lands that were historically irrigated by the shares and prove dry-up of those lands. We
contacted the ditch company in an effort to identify the historically irrigated land associated with the 10
shares owned by NCCI. We were informed that the shares might have originated from a block of shares
that have been owned by the ditch company but have no historical use. The ditch company reportedly
sold these shares to generate revenue for the Coal Ridge Waste Dam improvements. [f this is indeed the
source of the 10 shares owned by NCCI, the shares may be very difficult [o use for anything other than
irrigation.
Unless historically irrigated lands can be identified, we recommend obtaining atwo-year lease for 12.0
acre-feet of replacement water annually (10.80 acre-feet plus transit losses). We believe that a lease may
be obtained at the rate of $150 to $250 per acre-foot per year, or about $1,800 to $3,000 per year.
