Re: Camp Bird Mine, Permit M -1982 -090, Notice of Pending Designation as a Designated Mining
Operation
Dear Mr. Butters,
As a result of a review of the present and foreseen operational conditions of the Camp Bird Mine,
including site geology and geochemistry, potential ore materials to be extracted, the chemicals and
reagents that will be necessary to use for water treatment, and other pertinent permit file documents,
the Division has determined that the Camp Bird Mine, permit no. M- 1982 -090 is a Designated Mining
Operation (DMO). This determination is made in conformance with provisions of the Rules and
Regulations of Hard Rock, Metal, and Designated Mining Operations ( "Rules "), and applicable sections of
the Colorado Mined Land Reclamation Act (C.R.S. §§ 34- 32- 101,et seq.) ( "Act ").
Rule 7.2.2(1) provides that the Division may notify an Operator of the Division's determination that an
existing or proposed mining operation is, or has reasonable potential to be, a DMO.
Rule 7.2.1(1) and §103(3.5)(a) of the Act state that the Division's determination of a DMO will be based
on criteria described in the definition of a DMO, found in Rule 1.1(14).
Pursuant to Rule 7.2.2(2) the Division is required to accompany the Notice of DMO determination by the
factual statements used in the determination.
The Act and Rules define a Designated Mining Operation to be a mining operation at which acid- or
toxic - forming materials will be exposed or disturbed as a result of mining operations. Therefore, the
specific criteria used by the Division to determine that this operation is a DMO based upon the exposure
of acid- or toxic - forming materials are the following:
1. Activities at the Camp Bird Mine currently consist of rehabilitation of the main portal toward the
existing underground workings. Proposed mining operations have the potential to affect the
hydrological balance both in quality and quantity. In order to continue to proceed toward
potential mining reasonably anticipated activities will include dewatering, water treatment, and
discharge. A water treatment facility will utilize chemicals, which may be toxic or acidic, and
must provide proper containment; the treatment plant must be considered an Environmental
Protection Facility (EPF) and addressed through an Environmental Protection Plan (EPP).
