RE: Weed Control Policy
From July 17, 1998 (Revised February 14, 2002, October 28, 2002)
The Governor's Office has made it know to state agencies of the state's need to effectively control the spread
of noxious weeds. This policy is intended to address the management of noxious weeds that can occur at
mine sites. The question for the Division is what is an acceptable level of weeds at an active mining
operation, or on a reclaimed site at the time of financial warranty release request, in terms of the
requirements of the Act, Rules, and bond release? The following document is intended to provide the staff
and operators guidance on this issue.
Guideline for the Management of Noxious Weeds at Hard Rock and Construction Material
Mining Operations
1. Introduction:
The infestation of noxious weeds on agricultural land and rangeland is a serious problem in Colorado
and other western states. Reduced productivity, loss of desirable plant species diversity and wildlife
habitat, and livestock health hazards can result.from noxious weed infestations. Land disturbances
associated with mining provide conditions conducive to the invasion and spread of a number of
undesirable plant species.
This guide has been developed to provide guidance on the management the of noxious weeds on
reclaimed azeas and other azeas that may be affected by mining activities, due to the lack of specific
direction in the Act and Regulations: The purpose of the guideline is to set forth Boazd policy based on
the Boazd's interpretation of the Act, Regulations, and common sense, for the effective control of
noxious weeds at permitted mine sites. It is also intended to provide staff guidance as to when an
operator has established an acceptable type of plant cover so that the Office may consider financial and
performance warranty release.
