Action
Final rule; decision on petition for reconsideration.
Summary
On June 20, 1994, RSPA amended the Hazardous Materials Regulations (HMR) by designating 15 hazardous substances as hazardous materials and amending the reportable quantity (RQ) for 34 other hazardous substances already designated as hazardous materials. Petitioners, metals mining and refining companies, requested that the rule modify the HMR to except from the hazardous material designation copper, molybdenum and zinc concentrates containing small amounts of lead sulfide, a hazardous substance. Alternatively, petitioners asked that the effective date of the rule be stayed to allow for the docket to be opened for public comment. The petition is denied. The effective date of that part of the rule that reduces the RQ for lead sulfide is extended for 90 days.
