Exposed Groundwater Compliance Process
Dear Mr. Loloff:
STATE OF COLORADO
Loretta Pineda
Director
On April 30, 2010, the Division of Reclamation, Mining and Safety (Division) sent a letter to the
mine site indicated above discussing the Division's requirement for the protection of water
resources at mining sites with exposed groundwater.
The letter required all sand and gravel mining Operators /Permittee to comply with the
requirements of the Colorado Reclamation Act and the Mineral Rules and Regulations for the
protection of water resources. The letter required Operators /Permittee to provide information
to the Division demonstrating they could replace long -term injurious stream depletions that
result from mining related exposure of groundwater. The letter indentified four (4) approaches
to satisfy this requirement. This information was due by April 30, 2011. The Permittee failed to
comply with the requirements of the letter by the due date. Mr. Loloff contacted the Division
in December 2011 to acknowledge the error and agreed to work with the Division to resolve
the issue. Since Mr. Loloff contacted the Division and acknowledged the error, the Division will
not issue a possible violation for failure to comply with the letter and the requirements of CRS
34- 32.5- 116(4)(h), Rule 3.1.6(1)(a) and 6.4.5(2)(c) at this time. To avoid a future possible
violation, the Permittee must continue to work with the Division and account for the Tong -term
groundwater exposure at the site.
The following procedure must be followed by the Permittee to avoid a future possible violation:
1. Submit a technical revision within 60 days (April 2, 2012) from the date of this letter to
provide an alternate reclamation plan for installation of a slurry wall (Option 3 in the
March 30, 2010 letter). The technical revision must be filed in accordance with Rule 1.9
and included the required $216.00 fee.
As discussed during the January 20, 2012 inspection and subsequent conversations, the Division
and Permittee agree the most feasible and cost effective alternate reclamation plan at the site is a
slurry wall. The technical revision must state the Permittee is providing an alternate reclamation
