TR-34 to Permit M-1977-342 <br /> Environmental Protection Plan <br /> Monitoring: Chemical storage containers will be routinely inspected in accordance with the <br /> SPCC by Mill personnel to assess effectiveness and integrity of each EPF system. The tanks are <br /> generally equipped with level detectors and local alarms that warn of high tank levels. <br /> Maintenance and/or updates to facilities, systems, equipment, or procedures are performed <br /> as needed to be protective of the environment and to prevent releases. <br /> Mill EPF 2.13—Carbon Dioxide Storage: Carbon dioxide will be used at the Mill WTP to neutralize <br /> the pH of effluent water. Bulk liquid CO2 will be stored on the south side of the WTP building in <br /> a 775 gallon (4,929 pounds) Microbulk Storage Tank. <br /> Effectiveness: Any CO2 release would be in gaseous form. CO2 alarms will be installed to <br /> indicate the presence of a leak. <br /> Monitoring: Chemical storage containers will be routinely inspected in accordance with the <br /> SPCC by Mill personnel to assess effectiveness and integrity of each EPF system. The tanks are <br /> generally equipped with level detectors and local alarms that warn of high tank levels. <br /> Maintenance and/or updates to facilities, systems, equipment, or procedures are performed <br /> as needed to be protective of the environment and to prevent releases. <br /> 7.2.3. Stormwater Diversion System <br /> Mill EPF 3.1 — Stormwater Diversion System: The following stormwater diversion systems <br /> intercept clean water and divert it around the Mill facilities: <br /> • The Ultimate Canal on the west and north ends of the TSF diverts un-impacted <br /> stormwater around the north end of the property to the Williams Fork River; and <br /> • The Upper Bypass Pipeline on the southwest portion of the Mill property diverts water <br /> through an underground diversion pipe to the Williams Fork River. <br /> See Section 10.2 and the Henderson SWMP for additional information on stormwater diversion <br /> systems. <br /> Effectiveness:The stormwater diversion canals and pipelines have been effective in preventing <br /> the amount of stormwater that can come into contact with disturbed land, designated <br /> chemicals and toxic or acid forming materials. As a result,the potential pollution of stormwater <br /> is greatly reduced. <br /> Monitoring: The stormwater system is inspected twice per year in accordance with <br /> Henderson's SWMP (see Section 10.2 for additional information). <br /> Climax Molybdenum Company August,2021 <br /> Henderson Operations Page 29 of 45 <br />
