Climax Molybdenum Company
Permit No. M- 1977 -493
T -3 Designated Chemicals
The chemicals listed and discussed herein are those used specifically in: 1) the extractive metallurgical
processing of molybdenite ore to produce MoS concentrate; and 2) the wastewater treatment system at
Climax. The Climax Mine presently is not producing molybdenum concentrates, thus most of the
designated chemicals associated with metallurgical processing are not currently present on site.
However, since all or some of these chemicals may again be utilized when operations recommence, their
discussion is relevant. Information relative to water treatment chemicals used at the site is also provided,
however, these are not identified as designated chemicals.
The information provided regarding designated chemicals is presented as the best information currently
available. These chemicals, quantities, and concentrations may vary based upon production needs and
processes. For example, brand name chemicals such as (but not limited to) Nalco 9741 may be changed
out for different brands of similar chemicals based on factors such as cost, effectiveness, material
handling requirements related to safety, or environmental reasons. Changes in brand and reagent usage
are a part of the production process and are not considered to be grounds for notification to the DRMS.
However, notification to the DRMS will be made per the review /reporting discussed in Section T -1.1.2 in
the event that: 1) new types of chemicals, not discussed herein, are added to the process; 2) the storage
location of a designated chemical is changed; or 3) the specific containment facility for a designated
chemical must be modified.
TR -14 described the new mill and accessory buildings for use during resumed production, however the
final design and layout of the mill and accessory buildings had not been fully developed at that time. TR-
14 designated the mill building as a location for several Environmental Protection Facilities (EPFs)
associated with designated chemicals. Additional details of the mill facility have now been developed and
general arrangement drawings of the entire mill and of the reagent storage and containment areas are
provided as Figures AM- 06 -T -06 and AM- 06 -T -07. Climax will submit additional information regarding the
new facilities, as necessary, prior to recommencement of production.
