As show on this table, it is estimated that about 0.32 acres of US Forest Service managed land
will be disturbed.
DRAINAGE AND SEDIMENT CONTROL
The following drainage and sediment control measures will be employed to reduce erosion and
sediment at the site:
➢ Both the access road and the parking pad will be dressed as needed with an all- season
gravel to reduce sediment yield;
HAZARDOUS MATERIALS
No hazardous materials such as explosives or bulk petroleum products will be stored at the core
logging building or pad area.
RECLAMATION
RGS will implement the same reclamation measures for the access road and constructed pad
as is approved for the Bulldog Mine facilities area.
Most of the project site was previously disturbed by Homestake for its Bulldog Mine operations
and was reclaimed. RGS plans to principally contain its proposed facilities within the
boundaries of that previous disturbance. Past Homestake reclamation practices has shown that
the site can be successfully reclaimed.
The emphasis of RGS - proposed reclamation at the site will be as follows:
➢ Removal of fence;
➢ Fertilize, mulch and seed.
RIO GRANDE
SILVER, INC.
Compacted areas such as the access drive and compacted areas will be ripped or disked or
otherwise left in a roughened condition. The site will be seeded using the species list contained
in the Stage 2 District -Wide Exploration Plan of Operation that was approved by the Forest
Service in 2009. RGS will monitor reclaimed sites for reclamation success according to the
requirements of the Forest Service and state of Colorado. Areas to be monitored will include re-
vegetation success, erosion, and undesirable and noxious weeds.
ENVIRONMENTAL MANAGEMENT AND MITIGATION
All management and mitigation measures described in the approved operations plan for the
Bulldog decline and facilities area will apply to this TR. RGS will utilize management and
mitigation practices that are based on company policies, governmental laws and regulations,
current technology, and accepted management practices. The objectives of these practices are
to reduce or avoid impacts to the environment and to reclaim disturbed areas.
