RE: Hukill Gulch Millsite, DRMS File No. M-2009-076. Designated Chemicals.
Dear Mr. McHale,
The Division of Reclamation, Mining and Safety (Division) determines if a chemical will be designated
based on the definition of "Designated Chemicals" as described in Rule 1.1 (13) of the Mineral Rules and
Regulations of the Colorado Mined Land Reclamation Board for Hard Rock, Metal and Designated
Mining Operations. The Division takes into consideration the Material Safety Data Sheet (MSDS), other
information about the*chemical provided by the applicant and other verifiable information sources for
the chemical to determine if a substance fits the definition.
The Division does not maintain a list of designated chemicals because the process is necessarily reactive
to the chemicals proposed for use by applicants. For example, the Division reviewed an application
proposing to use another form of Xanthate, and based on the information supplied by the applicant this
material was considered to be a designated chemical. However, after receiving your letter, I reviewed
the MSDS sheet provided in the submitted 110d permit application for AERO® 317 Xanthate and believe
this form of Xanthate does not meet the definition of a designated chemical.
Given this, you will not need to supply an Emergency Response Plan for AERO° 317 Xanthate as outlined
in Rule 8.3.
Sincerely,
Jared Ebert
Environmental Protections Specialist, DRMS
