The Orthodox St. site is classified under the Clean Air Act as a Stationary Source Minor discharger of air pollutants. While maintaining a good relationship with state and federal regulations, AMC did encounter issues with its soil that had resulted from the site’s use of radioactive material. In 1963, Atlantic Metals Corp. acquired a license to work with magnesium-thorium. The license was terminated by AMC in 1971, but not before radioactive residue found its way into the ground outside of building #4. Inspections were conducted by the Nuclear Regulatory Commission in the late 90s, and AMC complied with the commission’s recommendations to re-identify the radioactive hotspot at building #4. (Source)
