Designated Chemicals Emergency Response Plan Climax Molybdenum Company Permit 1977 -493 T -A -1 Introduction T -A -1.1 Purpose and Objectives This Appendix to the Environmental Protection Plan contains information found in the Climax Mine site - wide Emergency Response Action Plan (ERAP). The ERAP was developed to provide a formal emergency preparedness program that protects human health and property in the event of an emergency such as fire, explosion, etc. The ERAP also formalizes the arrangements with local police, fire departments, and hospitals in case of an emergency. Employees have access to the ERAP via the company intranet and are trained on its contents. The ERAP is maintained onsite to reflect current site conditions. This Emergency Response Plan for Designated Chemicals has been prepared in accordance with Rule 8.3 of the MLRB Hard Rock/Metal Mining Rules, and provides information specific to designated chemicals only. This Appendix indicates the designated chemicals onsite at Climax during periods of production, outlines emergency response procedures for designated chemicals, identifies contact people associated with responding to emergencies, and contains a brief discussion of the location of the designated chemicals and associated controls. The location of the reagent storage area within the mill facility is indicated on EPP Figure AM- 06 -T -06. The general arrangement and containment details of the reagent storage area are presented on EPP Figure AM- 06 -T -07. T -A -2 Designated Chemicals The chemicals listed and discussed herein are those used specifically in the extractive metallurgical processing of molybdenite ore to produce molybdenum disulfide (MoS concentrate. The Climax Mine is not presently in production, thus, most of the designated chemicals associated with metallurgical processing are not present on the site. However, since all or some of these chemicals may again be utilized when operations recommence, their discussion is relevant. 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) Empicol (Syntex) or Nalco 9741 may be changed out for different brands of similar chemicals based on factors such as cost, effectiveness, or handling considerations. Changes in brand and reagent usage are a part of the production process and are not considered to be grounds for significantly altering this Appendix. However, updates to the ERAP will be made 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 enlarged. Updates may also be made to acknowledge changes in site emergency contacts. When production at Climax recommences, designated chemicals will be stored in the reagent area of the mill, as indicated on EPP 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, including a list and location of materials, supplies and equipment for containing, controlling and cleaning up excursions or releases of designated chemicals. T - A - 2.1 List of Chemicals and Specific Locations Designated chemicals used at Climax during periods of production are listed in Table T -A -1. The table includes the list of designated chemicals used in the froth flotation metallurgical process for concentrating MoS This list includes the storage location, the type and capacity of the storage container and identifies the presence of secondary containment associated with the design of the reagent storage area.
