Designated Chemicals Emergency Response Plan Climax Molybdenum Company <br /> Permit 1977-493 <br /> T-A-1 Introduction <br /> T-A-1.1 Purpose and Objectives <br /> This Appendix to the Environmental Protection Plan contains information found in the Climax Mine site- <br /> wide Emergency Response Action Plan (ERAP). The ERAP was developed to provide a formal <br /> emergency preparedness program that protects human health and property in the event of an emergency <br /> such as fire, explosion, etc. The ERAP also formalizes the arrangements with local police, fire <br /> departments, and hospitals in case of an emergency. Employees have access to the ERAP via the <br /> company intranet and are trained on its contents. The ERAP is maintained onsite to reflect current site <br /> conditions. This Emergency Response Plan for Designated Chemicals has been prepared in accordance <br /> with Rule 8.3 of the MLRB Hard Rock/Metal Mining Rules, and provides information specific to <br /> designated chemicals only. <br /> This Appendix indicates the designated chemicals onsite at Climax during periods of production, outlines <br /> emergency response procedures for designated chemicals, identifies contact people associated with <br /> responding to emergencies, and contains a brief discussion of the location of the designated chemicals <br /> and associated controls. The location of the reagent storage area within the mill facility is indicated on <br /> EPP Figure AM-06-T-05. The general arrangement and containment details of the reagent storage area <br /> are presented on EPP Figure AM-06-T-06. <br /> T-A-2 Designated Chemicals <br /> The chemicals listed and discussed herein are those used specifically in the extractive metallurgical <br /> processing of molybdenite ore to produce molybdenum disulfide (MoS2) concentrate. The information <br /> provided regarding designated chemicals is presented as the best information currently available. These <br /> chemicals, quantities, and concentrations may vary based upon production needs and processes. For <br /> example, brand name chemicals such as (but not limited to) Nalco may be changed out for different <br /> brands of similar chemicals based on factors such as cost, effectiveness, or handling considerations. <br /> Changes in brand and reagent usage are a part of the production process and are not considered to be <br /> grounds for significantly altering this Appendix. However, updates will be made in the event that 1) new <br /> types of chemicals, not discussed herein, are added to the process; 2) the storage location of a <br /> designated chemical is changed; or 3) the specific containment facility for a designated chemical must be <br /> enlarged. Updates may also be made to acknowledge changes in site emergency contacts. <br /> Designated chemicals are stored in the reagent area of the mill, as indicated on EPP Figures AM-06-T-05 <br /> and AM-06-T-06. <br /> T-A-2.1 List of Chemicals and Specific Locations <br /> Designated chemicals used at Climax during periods of production are listed in Table T-A-1. The table <br /> includes the list of designated chemicals used in the froth flotation metallurgical process for concentrating <br /> MoS2. This list includes the storage location, the type and capacity of the storage container and identifies <br /> the presence of secondary containment associated with the design of the reagent storage area. <br /> EPP—Appendix A August 2018 T-A-1 <br />
