RE: Tamarisk and Russian Ol ive Management at Permitted Mine Sites
This policy supplements the Boazd approved Weed Control Policy, dated July 17, 1998 and
revised 2/14/02, and 10/28/02. This policy pertains just to tamarisk (salt cedaz) and Russian
olive.
As we developed this amendment to the Boazd's Weed Policy, we received input from industry
associations, state weed experts, the Office of the- Executive Director, Department of Natural
Resources, the Attorney General's Office (AGO) and Office staff. We appreciate and thank
those that provided comments and suggestions.
Our existing Weed Control Policy addresses noxious weeds and provides guidance for mine site
control and/or eradication of noxious weeds. The policy currently excludes tamarisk or Russian
olive. However, these species are now infestation problems on some permitted sites.
Where tamarisk and/or Russian olive occur and the State Weed Rules do not require eradication
from the region in which the mining operation occurs, the Board directs the DMG to process
reclamation liability release requests if:
The release area was in reclamation prior to January 19, 2005 (grandfathered); and
2. acceptable evidence is provided to the Division that the approved reclamation plan has
been fully implemented; and
3. the release area satisfies all other provisions of the Act, Rules and Regulations, and the
approved permit application.
However, where tamarisk and/or Russian olive are the sole source for infestation on to adjacent
properties that are free of tamarisk and/or Russian olive, these plants shall be eradicated just as
any other noxious weed would be required to be eradicated from reclaimed areas under these
circumstances.
