• TR 82: TR 82 to Amendment 10 was proposed and approved which addresses
the modification of the Phase I liner completion location, defer construction of

• TR 83: TR 83 to Amendment 10 was proposed and approved which addressed
the haulage of crushed ore and agglomerated tailings from the LOB to the Squaw

Enhancement and general maintenance of storm water control features continued in 2016.
Other Amendment 10 construction activities will continue throughout 2017 and beyond.
Reclamation accomplished in 2016 included the following projects:
Approximately 15.67 acres of disturbance associated with the Cresson Project were reclaimed
in 2016 as shown on the figures in Attachment 1. All areas were re-contoured and six inches of
growth medium was applied prior to seeding.
Weed control techniques were implemented within the Cresson Project area in the summer of
2016 and will continue in the spring and potentially fall of 2017 (Attachment 1, Figure 2). A full
report prepared by Habitat Management can be found in Attachment 2. Herbicides were applied
by a certified applicator to manage noxious weeds in and around the Cresson Project including
Canada thistle, musk thistle, yellow toadflax, Dalmatian toadflax and common mullein. These
herbicides are broadleaf selective and have a very low potential for injury to surrounding, native
grass species. A surfactant was included in the herbicide mixture to increase leaf adhesion and
absorption while blue marker dye was included in the mixture to track applications. Spatial data
was collected to track predominant weeds and track progression and control accordingly.
Per the requirements of C.R.S. 34-32-116(3), and C.R.S. 34-32.5-116(3)(a):
Reclamation accomplished to date: Approximately 421.67 acres
