Subject: Raton Creek Mine TR-22 Proposed Species Diversity Standard.
Dear Janet:
Based upon our discussions this afternoon of the grass cover values from the
2009 and 2005 reclamation monitoring efforts, along with the concerns you
expressed in your e-mail of today, Energy Fuels Coal Inc., is proposing the
following species diversity standard.
The discussion on Permit Page 522 relative to species diversity will be
modified to read:
Grasses: At least 60 percent of the total relative allowable vegetative
cover with no one grass species comprising more than 50 percent of the
total allowable cover.
Forbs: At least 10 percent of the total allowable vegetative cover.
Examination of the 2009 cover data, document that the total allowable cover
value was 30.50 percent, with grasses contributing 63.61 percent of the
total relative allowable cover and with the most dominant grass,
contributing only 33.39 percent of the total relative allowable cover.
In 2005, the total allowable cover was found to average 28.99 percent, with
grasses contributing 63.97 percent of the total relative allowable cover
with the most dominant grass contributing only 91.89 percent of the total
relative allowable cover.
It is our opinion that this proposed standard more accurately addresses the
Division's concerns of having a diverse plant community growing on the
relaimed areas, while at the same is a standard that Energy Fuels Coal can
comply with.
If you have any additional comments or questions regarding this issue,
please do not hesitate to contact me either in my office at 970-638-4962 or
via e-mail.
Thanks,
