Abstract:  THE AMBLER ASBESTOS PILES SITE IS LOCATED IN THE SOUTHWESTERN PORTION OF THE BOROUGH OF AMBLER, MONTGOMERY COUNTY, PENNSYLVANIA. LAND AROUND THE SITE IS USED FOR INDUSTRIAL, RESIDENTIAL, COMMERCIAL, AND TRANSPORTATION PURPOSES. THE SITE IS BORDERED ON THE WEST BY WISSAHICKON CREEK AND ITS FLOOD PLAIN. A LOW DENSITY HOUSING DEVELOPMENT LIES TO THE SOUTHWEST. THE SITE CONSISTS OF FOUR DISTINCT AREAS OF ASBESTOS CONTAMINATION; THE LOCUST STREET PILE, THE PLANT PILE, THE PIPE PLANT DUMP, AND THE ASBESTOS SETTLING BASINS/FILTER BED LAGOONS. THE WASTE PILES OF CONCERN IN THIS OPERABLE UNIT ARE THE LOCUST STREET PILE AND THE PLANT PILE. WITHIN A 0.25 MILE RADIUS OF THE LOCUST STREET PILE ARE APPROXIMATELY 40 RESIDENCES AND A PUBLIC PLAYGROUND THAT WAS CLOSED IN 1984. THE K&M COMPANY OWNED AND OPERATED THE SITE FROM THE LATE 1800S TO 1962, AND PRODUCED ASBESTOS PRODUCTS SUCH AS PAPER, MILLBOARD, ELECTRICAL INSULATION, LININGS, CONVEYOR BELTS, AND HIGH PRESSURE PECKINGS. THE PRIMARY WASTES GENERATED AND DISPOSED OF IN THE LOCUST STREET AND PLANT PILES DURING THAT PERIOD WERE SPENT MAGNESIUM/CALCIUM (FROM PHARMACEUTICAL OPERATIONS) AND ASBESTOS PROCESS WASTE. IN 1962, CERTAINTEED CORPORATION PURCHASED A PORTION OF THE SITE AND FACILITIES FROM K&M AND MANUFACTURED ASBESTOS-CEMENT PIPE AT THE PLANT. NICOLET INDUSTRIES, INC. PURCHASED THE REMAINDER OF THE SITE AND MANUFACTURED ASBESTOS MILLBOARD AND MONOLITHIC PRODUCTS. THE LOCUST STREET PILE CONTINUED TO RECEIVE ASBESTOS WASTE FROM NICOLET UNTIL SOMETIME AFTER 1964; HOWEVER, WASTE CONTINUED TO BE DEPOSITED ON THE PLANT PILE UNTIL 1980. EPA AND THE PENNSYLVANIA DEPARTMENT OF ENVIRONMENTAL RESOURCES CONDUCTED THEIR FIRST INVESTIGATION OF THE SITE IN 1971, NOTING VISIBLE EMISSIONS AND SUBSTANTIAL DUST CONCENTRATIONS ATTRIBUTED TO ASBESTOS. SUBSEQUENT INVESTIGATIONS OF THE SURFACE WATER, BULK WASTE SAMPLES AND AIR SAMPLES IN 1983 REVEALED ASBESTOS CONTAMINATION. IN SEPTEMBER 1983, THE CENTERS FOR DISEASE CONTROL ISSUED A PUBLIC HEALTH ADVISORY RECOMMENDING THE CLOSURE OF THE NEARBY PLAYGROUND. IN 1984, EPA IMPLEMENTED EMERGENCY RESPONSE ACTIONS TO ESTABLISH A SOIL AND VEGETATIVE COVER, INSTALL A DRAINAGE SYSTEM, AND PROVIDE EROSION CONTROL MEASURES OVER THE LOCUST PILE. IN ADDITION, NICOLET HAD COVERED THE PLANT PILE BY JUNE 1984. THE PRIMARY CONTAMINANT OF CONCERN AFFECTING THE SEDIMENTS, SURFACE WATER, AND DEBRIS IS ASBESTOS.

THE SELECTED REMEDIAL ACTION FOR THIS SITE INCLUDES; INSTALLATION OF A GEOTEXTILE AND SOIL COVER ON THE EXPOSED AREAS OF WASTE PILES; EROSION CONTROL/REPAIR ON WASTE PILE SLOPES TO FACILITATE VEGETATION; PUMP AND TREATMENT (USING FILTERS) OF SURFACE WATER FROM LAGOON AND SETTLING BASINS WITH ONSITE DISCHARGE, BACKFILLING AND REGRADING LAGOON AND SETTLING BASINS TO PROMOTE POSITIVE DRAINAGE, AND ONSITE DISPOSAL OF COLLECTED SEDIMENTS AND ASBESTOS ON THE WASTE PILES; IMPLEMENTATION OF SLOPE STABILITY CONTROL MEASURES, IF DEEMED NECESSARY AFTER TESTING; INSTALLATION OF GABIONS OR RIP-RAP TO PREVENT SCOURING ACTION OF WISSAHICKON CREEK ON THE WASTE PILES; RUNOFF COLLECTION AND TREATMENT; PREPARATION OF A CONTINGENCY PLAN; AND ACCESS RESTRUCTIONS. THE ESTIMATED CAPITAL COST FOR THIS REMEDIAL ACTION IS $5,135,000, WITH ESTIMATED ANNUAL O&M COSTS OF $46,000 TO $63,000 FOR YEARS 2 THROUGH 6 AND $33,000 FOR YEARS 6 THROUGH 30.
 
Remedy:  THE SELECTED REMEDY FOR THE FIRST OPERABLE UNIT SEEKS TO PREVENT THE RELEASE OF ASBESTOS FROM THE SITE. A VEGETATIVE/SOIL COVER WILL BE INSTALLED OVER EACH OF THE TWO ASBESTOS-CONTAINING WASTE PILES (LOCUST STREET-PILE AND PLANT PILE) TO PREVENT AIRBORNE EMISSIONS, RUNOFF WILL BE COLLECTED AND TREATED TO ASSURE NO WATERBORNE ASBESTOS CAN GO OFF SITE.

ADDITIONAL COMPONENTS OF THE SELECTED REMEDY ARE AS FOLLOWS:

- A GEOTEXTILE AND SOIL COVER WILL BE INSTALLED ON THE EXPOSED PLATEAU AREAS OF THE LOCUST STREET AND PLANT PILES AND ON THE EXPOSED SIDE SLOPE AREAS OF THE LOCUST STREET PILE.
- REPAIR TO EROSION ON WASTE PILE SLOPES DUE TO STORM EVENTS, SOIL CREEP, FREEZE/THAW EFFECTS, ETC., WILL BE IMPLEMENTED.
- WATER FROM THE LAGOON AND SETTLING BASINS WILL BE PUMPED AND FILTERED FOR REMOVAL OF ASBESTOS FIBERS. DISCHARGE OF THE TREATED WATER WILL OCCUR ON-SITE WITH PLACEMENT OF FILTER BACKWASH ON WASTE PILES.
- THE LAGOON AND SETTLING BASINS WILL BE BACKFILLED WITH CLEAN LOW PERMEABILITY COMPACTED SOIL BRINGING THE DEPRESSION UP TO GRADE TO PROMOTE LONG-TERM POSITIVE DRAINAGE.
- ADDITIONAL BORINGS WILL BE COLLECTED INTO AND THROUGH THE PILE SIDE SLOPES TO SUPPLEMENT SLOPE STABILITY ANALYSIS PREVIOUSLY PERFORMED.
- SLOPE STABILITY CONTROL MEASURES WILL BE ANALYZED AND IMPLEMENTED IF THE AFOREMENTIONED STUDIES ARE FOUND TO PROVIDE EVIDENCE OF SLOPE INSTABILITY.
- GABIONS OR RIP-RAP WILL BE INSTALLED TO PROTECT THE TOE OF THE LOCUST STREET PILE FROM THE SCOURING ACTION OF THE WISSAHICKON CREEK.
- EROSION/SEDIMENTATION CONTROLS DURING REMEDIAL ACTIVITIES WILL BE IMPLEMENTED TO FACILITATE THE ESTABLISHMENT OF VEGETATION.
- AIR MONITORING FOR ASBESTOS WILL OCCUR DURING REMEDIAL ACTIVITIES (PERSONNEL AND ENVIRONMENTAL).
- POST-CLOSURE INSPECTIONS, MAINTENANCE OF THE PILES, LAGOON, AND SETTLING BASIN AREAS, AND PREPARATION OF A CONTINGENCY PLAN WILL BE ACCOMPLISHED.

OTHER ALTERNATIVES WILL BE FURTHER EVALUATED AS PART OF A PREREMEDIAL DESIGN STUDY TO DETERMINE WHETHER TO PILOT TEST FOR, AND POSSIBLY INSTITUTE, ONE OF THESE ALTERNATIVES FOR THE SITE. IF FOUND TO BE UNACCEPTABLE, BASED UPON EPA'S EVALUATION CRITERIA UNDER CERCLA FOR REMEDIAL ACTIONS, THE ALTERNATIVE 4 WILL IMMEDIATELY BE IMPLEMENTED.

IF ANY ALTERNATIVE PROCESSES ARE FOUND TO BE ACCEPTABLE, BASED UPON EPA'S EVALUATION UNDER CERCLA FOR REMEDIAL ACTIONS, EPA WOULD AMEND THE ROD. PUBLIC COMMENT WOULD BE SOLICITED IN THE EVENT OF ROD AMENDMENT.
