Abstract
The Cimarron Mining site consists of two inactive ore-processing mills in Carrizozo, Lincoln County, New Mexico. Operable Unit 2 (OU2), which is the focus of the Record of Decision (ROD), addresses contamination at the 7.5-acre Sierra Blanca mill location. In 1990, EPA investigations revealed 43 cubic yards of tank sediment, 182 cubic yards of material pile soil and rock, and 345 cubic yards of discharge pit sediment and soil contaminated with high concentrations of metals, particularly lead at the Sierra Blanca location. The ROD addresses the final remedial action of the soil and waste piles at the Sierra Blanca mill location, as OU2. The primary contaminants of concern affecting the soil, sediment, debris, and sludge are metals including arsenic and lead. The selected remedial action for the site includes excavating and treating onsite 225 cubic yards of contaminated material piles and tank sediment, including cinder block trench sediment which failed the TCLP test, using cement solidification and stabilization; excavating and disposing of 345 cubic yards of contaminated surficial soil and sludge.
