EPA v. DENVER RADIUM SITE OU II/SITE # 01(02) COMMERCIAL IRON & MET

Case summary

THE PORTION OF OU II OF THE DENVER RADIUM SITE WHICH IS OWNED AND OPERATED BY THE RESPONDENTS IS LOCATED AT 1100 UMATILLA STREET IN DENVER, COLORADO. THE SITE LIES APPROXIMATELY 1000 FEET EAST OF THE SOUTH PLATTE RIVER AND 2000 FEET SOUTH OF WEST COLFAX AVENUE (SW 1/4 OF NW 1/4 AND NW 1/4 OF SW 1/4 OF SECTION 4, T 4S, R 68W) WITHIN A LIGHT INDUSTRIAL AREA OF THE CITY. THE SITE IS ENTIRELY ENCLOSED BY A SIX-FOOT, CHAIN LINK SECURITY FENCE. THE EPA PLACED THE SITE ON THE NPL ON 09/08/83. DURING THE SUMMER OF 1992, APPROXIMATELY 640 TONS OF LEAD-ONLY CONTAMINATED SOILS WERE REMOVED FROM THE AREA OF THE EAST STORAGE BUILDING, TO ENABLE EPA CONTRACTORS TO ACCESS RADIUM CONTAMINATED SOILS FOR DISPOSAL. THIS LEAD-ONLY SOIL, WHICH IS THE SUBJECT OF THIS REMOVAL ACTION, IS PRESENTLY LOCATED IN A PILE IN THE VICINITY OF THE SOUTHEAST WAREHOUSE ALONG THE EASTERN BOUNDARY OF THE SITE. LEAD ONLY CONTAMINATED SOIL IS ALSO LOCATED IN SEVERAL AREAS ON THE SITE BENEATH THE GROUND SURFACE. EPA AND COLORADO DEPARTMENT OF HEALTH HAVE CONDUCTED THREE SEPARATE STUDIES TO CHARACTERIZE THE NATURE AND EXTENT OF CONTAMINATION AT THE SITE. THE RESULTS OF THESE STUDIES ARE PRESENTED IN DOCUMENTS ATTACHED TO THIS ORDER.
