RE: Lafarge West, Inc.'s South Platte Combined Replacement Plan (WDID 0202581)
Water Division 1, Water Districts 2
Approval Period: November 1, 2009 through October 31, 2010
Contact phone number for Ms. Sira W. Sartori. 303-452-6611
Dear Ms. Sartori:
We have received your letter of August 31, 2009 requesting renewal of the substitute water
supply plan ("SWSP") to cover depletions caused by gravel mining operations at multiple mine sites
operated by Lafarge West, Inc. ("Lafarge" or "Applicant") along the South Platte River. This SWSP
proposes to replace depletions which occur at four different mine sites, specifically: 1) Howe Pit, M-78-
052 (WDID 0203009), 2) the Mann Lakes, M-82-147 (WDID 0203012), 3) the Fort Lupton Pit (Riverbend
West), M-85-088 (WDID 0203013) 4) Lupton Lakes (Riverbend East), M-04-078 (WDID 0203041). The
required fee of $1027 ($257x4) has been submitted. Lafarge previously operated Tanabe Pit (M-00-
002), Dunes Development (M-99-093), Riverbend Operation (M-00-016) and Stagecoach Stop Property
(M83-067) under the combined SWSP. The State Engineer approved the clay liner for the Tanabe Pit
and Dunes Development, which eliminated the need to replace new depletions from the evaporation of
exposed ground water. Because there are no longer lagged depletions that affect the stream from the
previously mined sites at Tanabe Pit and Dunes Development, you did not include these sites in the
SWSP. According to the information received on March 4, 2009 Lafarge sold the Stagecoach Stop
Property to Albert Frei and Sons in February 2009, therefore Lafarge will not make replacements for this
site after March 2009. The replacement requirement for this site beginning in April 2009 will be the
responsibility of Albert Frei and Sons. The Riverbend Operation has been taken out of this SWSP as
Lafarge does not anticipate mining or exposing ground water during the period of this SWSP. In addition
currently there is no ground water exposed at the Riverbend Operation site.
Lafarge transferred the Howe Pit to Denver Water in May 2009. Therefore, Denver Water will be
responsible for replacement of evaporative depletions at the Howe Pit site in the water year 2010.
Lafarge will batch concrete at the Howe Pit site.
As mentioned in the previous SWSP approval and based on previous information received
from the Applicant the Fort Lupton Pit site (M-85-088) is a "permitted reserve site" therefore
depending on the economic conditions mining may start anytime.
