2.0 Site Status Summary
The Shieldalloy Metallurgical Corporation (SMC) site is located in Newfield, New Jersey. Contamination is in the form of facility-generated slag and baghouse dust. The major contaminants are uranium and thorium, with daughters. The site is also on the NPL under CERCLA, because of past operations involving chromium-contaminated groundwater. In August 2001, SMC notified NRC that it had ceased production activities using source material. On August 27, 2001, the licensee provided notification and intent to decommission. The license was amended on November 4, 2002, to authorize only decommissioning activities that were previously permitted. The licensee submitted a revised license renewal application on May 1, 2003. At that time, the licensee estimated the cost of decommissioning to be approximately 1.8 million dollars.
The SMC facility manufactures or has manufactured specialty steel and super alloy additives, primary aluminum master alloys, metal carbides, powdered metals, and optical surfacing products. One of the raw materials that was used in its manufacturing processes from 1955 to 1998 is classified as “source material” under 10 CFR Part 40. This material, called pyrochlore, is a concentrated niobium ore containing greater than 0.05 percent natural uranium and natural thorium. SMC was licensed by the NRC to ship, receive, possess, use and store source material under SMB-743. During the manufacturing process, the facility generated slag, and baghouse dust. Currently, there is approximately 53,200 m3 (1,880,000 ft3) of slag and demolition debris and approximately 13,000 m3 (460,000 ft3) of baghouse dust contaminated with technologically enhanced uranium, thorium, and daughters stored on-site.
SMC submitted a DP on August 30, 2002, which was rejected by NRC staff, because of deficiencies. SMC submitted a revised DP in October 2005, which the NRC rejected in January 2006. The staff met with SMC in March 2006 to discuss the deficiencies in the DP and develop a path forward for submittal of an acceptable DP. The NRC staff and New Jersey Department of Environmental Protection (NJDEP) staff visited the site in April 2006 to discuss erosion control design. Pursuant to comments received at these interactions, SMC submitted a supplement to its DP in June 2006. The NRC staff completed its acceptance review of the supplement in September 2006 and determined that there is sufficient information to proceed with its technical review. The NRC's technical review resulted in the issuance of over 70 Requests for Additional Information. SMC addressed the deficiencies and submitted a revised plan in August 2009. The NRC did not start a review of the plan because of the imminent Agreement with New Jersey. The Agreement became effective on September 30, 2009 and regulatory authority was transferred to the Department of Environmental Protection’s Bureau of Environmental Radiation (BER).
SMC brought the transfer of their license to New Jersey to the DC Circuit Court of Appeals. The DC Circuit remanded authority to NRC in November of 2010. The NRC Commissioners subsequently voted to return authority to New Jersey. SMC appealed that decision and in December of 2012, the DC Circuit remanded authority back to NRC effective April 12, 2013. On August 5, 2013, the Commission reinstated New Jersey's authority to regulate Shieldalloy Metallurgical Corporation.
3.0 Major Technical or Regulatory Issues
SMC has found it difficult to sell the slag material. Several attempts to export the material have failed. SMC intended to sell the baghouse dust to a local cement manufacturer, however, no buyer has been found. Regardless of whether the sales occur, SMC proposed to dispose of these materials on-site in an engineered cell. The State of New Jersey requires licensees to terminate their licenses as per the timeliness regulations at N.J.A.C. 7:28-58.1 et seq.
