Abstract:  THE LIMESTONE ROAD SITE IS LOCATED 2.5 MILES EAST SOUTHEAST OF CUMBERLAND, ALLEGHENY COUNTY, MD ON THE WESTERN FLANK OF IRONS MOUNTAIN. THE 210-ACRE SITE CONSISTS OF TWO PARCELS OF LAND, THE FORMER DIGGS SANITATION COMPANY (DSC-20 ACRES) AND THE CUMBERLAND CEMENT AND SUPPLY COMPANY (CC&SC - 191 ACRES). THE SITE IS BORDERED ON THE SOUTHWEST BY SEVERAL RESIDENCES, AND IMMEDIATELY TO THE NORTHWEST LIE THE CUMBERLAND CITY DUMP AND UNDEVELOPED LAND. THE SITE INCLUDES LARGE AREAS OF LANDFILLED AND DUMPED COMMERCIAL RESIDENTIAL AND DEMOLITION REFUSE ON BOTH PROPERTIES. ABOUT 110 TONS OF A CHROMIUM CONTAINING SLUDGE WERE ALSO DISPOSED OF ON THE PROPERTIES. CURRENTLY, 18 RESIDENCES ARE WITHIN A HALF-MILE DOWNHILL OF THE SITE, 5 WITHIN 100 YARDS, AND ONE ON THE DIGGS PROPERTY. THE WATER SUPPLY FOR THESE RESIDENCES IS GROUND WATER FROM PRIVATE WELLS. GROUND WATER IN THE AREA OF THE SITE HAS THE POTENTIAL TO BE CONTAMINATED WITH INORGANIC AND ORGANIC CONSTITUENTS. IN THE MID 1970S, MR. CHARLES STEINER, PRESIDENT OF CC&SC, BEGAN ALLOWING VARIOUS CONTRACTORS TO DUMP CLEAN FILL (HOUSING DEMOLITION MATERIAL) ON THE PROPERTY TO PROVIDE A LARGER AND MORE LEVEL WORKING SURFACE. HOWEVER, A VARIETY OF WASTE HAS REPORTEDLY BEEN DUMPED INTO A RAVINE ON THE PROPERTY. IN APRIL 1981, MR. JOSEPH DIGGS, A LICENSED HAZARDOUS WASTE HAULER AND OWNER OF DSC, WAS ALLEGEDLY INVOLVED IN THE DUMPING OF 99 TONS OF HAZARDOUS WASTE CONTAINING CHROMIUM, LEAD, AND CADMIUM INTO A RAVINE ON CC&SC PROPERTY. IN ADDITION, AN ALLEGED 11 TONS OF HAZARDOUS WASTE HAVE BEEN REPORTEDLY DISPOSED OF ON THE DIGGS PROPERTY AS AN EXTENSION OF PREVIOUS FILLING AND GRADING OPERATIONS. THE NEARBY CUMBERLAND CITY DUMP FUNCTIONED AS A MUNICIPAL LANDFILL FROM 1932 TO 1968. FLY ASH, MISCELLANEOUS SOLID METAL WASTES, AND NUMEROUS TIRES ARE CURRENTLY EXPOSED ON THE NORTHERN AND SOUTHERN FACES OF THE DUMP. SEVERAL CRUSHED AND RUSTED DRUMS WERE NOTED ALONG THE BANKS OF THE INACTIVE LANDFILL. THE PRIMARY CONTAMINANTS OF CONCERN INCLUDE; VOCS, BASE-NEUTRAL COMPOUNDS, TCE, PCE, & HEAVY METALS.

THE SELECTED INTERIM REMEDIAL ACTION INCLUDES; SITE GRADING; CAPPING OF CONTAMINATED SOIL ON ALL PROPERTIES; FENCING OF BOTH PROPERTIES; CONTINUED MONITORING OF GROUNDWATER, SURFACE WATER, AND SEDIMENT; COMPLETE HISTORICAL REVIEW OF PERTINENT GEOLOGICAL INFORMATION; COLLECTION OF REGIONAL OFFSITE AND ONSITE GEOLOGICAL INFORMATION; CHEMICAL ANALYSIS OF THE SHALE TO DETERMINE ITS COMPOSITION; REEVALUATION AND ESTABLISHMENT OF BACKGROUND DATA CONTROL POINTS; FREQUENT SAMPLING TO INCREASE THE DATA BASE; INCREASE IN THE NUMBER OF STREAM AND RESIDENTIAL SAMPLING; EVALUATION OF THE EFFECTS OF NATURAL AND/OR DOMESTIC (PLUMBING) CONDITIONS ON THE OVERALL WATER QUALITY OF THE AREA. THE ESTIMATED CAPITAL COST IS $1,192,580. O&M COST WILL BE DETERMINED AFTER COMPLETION OF GROUND WATER STUDIES.
 
Remedy:  - SITE GRADING
- CAPPING OF CONTAMINATED SOIL ON ALL PROPERTIES
- FENCING OF BOTH PROPERTIES
- CONTINUED MONITORING OF GROUND WATER, SURFACE WATER AND SEDIMENT
- COMPLETE HISTORICAL REVIEW OF PERTINENT GEOLOGICAL INFORMATION
- COLLECTION OF REGIONAL, OFFSITE AND ONSITE GEOLOGICAL INFORMATION
- CHEMICAL ANALYSIS OF THE SHALE TO DETERMINE ITS COMPOSITION
- REEVALUATE AND ESTABLISH BACKGROUND DATA CONTROL POINTS
- FREQUENT SAMPLING TO INCREASE THE DATA BASE
- INCREASE THE NUMBER OF STREAM AND RESIDENTIAL SAMPLING
- EVALUATE THE EFFECTS OF NATURAL AND/OR DOMESTIC (PLUMBING) CONDITIONS ON THE OVERALL WATER QUALITY OF THE AREA
- A DECISION WILL BE MADE LATER REGARDING SURFACE WATER SEDIMENT AND GROUND WATER RUNON INTERCEPTION. THE ABOVE STUDIES, INCLUDING ANY ADDITIONAL FURTHER STUDIES WILL BE DONE TO CHARACTERIZE THE SITE IN TERMS OF THE GEOLOGY AND HYDROLOGY BY EPA AND THE MARYLAND WASTE MANAGEMENT ADMINISTRATION, AND EVALUATED FOR FUTURE REMEDIAL ACTION.
