Abstract:  THE MOYER LANDFILL IS AN INACTIVE PRIVATELY OWNED LANDFILL LOCATED IN LOWER PROVIDENCE TOWNSHIP IN MONTGOMERY COUNTY, PENNSYLVANIA. THE SITE WAS OPERATED AS A MUNICIPAL LANDFILL FROM THE 1940'S UNTIL APRIL 1981, DURING WHICH TIME IT RECEIVED MUNICIPAL REFUSE AND SEWAGE SLUDGES. ACCORDING TO LOCAL FEDERAL BUREAU OF INVESTIGATION (FBI) OFFICIALS, THE LANDFILL ACCEPTED A VARIETY OF SOLID AND LIQUID HAZARDOUS WASTES, INCLUDING POLY-CHLORINATED BIPHENYLS (PCBS), SOLVENTS PAINTS, LOW-LEVEL RADIOACTIVE WASTES, AND INCINERATED MATERIALS IN BULK FORM AND/OR CONTAINERIZED IN DRUMS. IN 1972, WHEN THE PENNSYLVANIA DEPT. OF ENVIRONMENTAL RESOURCES (PADER) RULES AND REGULATIONS BECAME MORE RESTRICTIVE, THIS LANDFILL WAS CITED, AND FINALLY IN 1981, IT WAS CLOSED AND BROUGHT INTO RECEIVERSHIP OF THE U.S. DISTRICT COURT.

THE SELECTED REMEDIAL ACTION FOR THIS SITE INCLUDES INTERIM SOIL CLAY CAPPING, COMPOSED OF A MATERIAL HAVING A PERMEABILITY OF 10-4/10-5 CM/SEC TO A DEPTH OF 36"; EROSION AND SEDIMENTATION CONTROL MEASURES; SURFACE WATER DIVERSION; LEACHATE COLLECTION, TREATMENT AND DISCHARGE; EXTRACTION, SCRUBBING AND UPGRADING METHANE GAS FOR DELIVERY TO THE PHILADELPHIA ELECTRIC COMPANY (PECO); SECURITY/FENCING MEASURES; GROUND WATER MONITORING; AND ALL CLOSURE ACTIVITIES IN COMPLIANCE WITH RCRA AT THE CONCLUSION OF THE GAS GENERATION PHASE (10 TO 20 YEARS). TOTAL CAPITAL COST FOR THE SELECTED REMEDIAL ALTERNATIVE IS ESTIMATED TO BE $6,298,500 WITH O&M COSTS APPROXIMATELY $332,000 PER YEAR. THIS ALTERNATIVE CONTEMPLATES BROAD REMEDIAL WORK AND ITS IMPLEMENTATION WILL DEPEND UPON THE SUCCESS OF THE GAS GENERATION/RECOVERY PROGRAM AND THE CONTRIBUTIONS FROM GENERATORS AND OTHER POTENTIALLY RESPONSIBLE PARTIES (PRPS). IF NEGOTIATIONS WITH THE PRPS FAIL AND/OR THE METHANE GAS ALTERNATIVE FAILS, EPA AND PADER RECOMMEND MISCELLANEOUS WORK PREPARATORY TO INSTALLATION OF A RCRA CAP (GRADING, FLATTENING OF STEEP SLOPES, RETAINING WALLS AND INSTALLATION OF A RIP-RAP AT AREAS THAT ARE MOST LIKELY TO BE ERODED); GAS VENTING AND MONITORING; SURFACE WATER COLLECTION AND DISCHARGE TO SKIPPACK CREEK; LEACHATE COLLECTION AND TREATMENT THAT WILL MEET THE 10-6 RISK LEVEL IN THE GROUND WATER AND DISCHARGE REQUIREMENTS IN THE STREAM; GROUND AND SURFACE WATER MONITORING; AND MAINTENANCE OF THE CAP. TOTAL CAPITAL COST FOR THIS ALTERNATIVE REMEDIAL ACTION IS ESTIMATED TO BE $15,384,800 WITH O&M COSTS OF $343,100 PER YEAR.
 
Remedy:  AFTER CAREFUL REVIEW AND CONSIDERATION OF SITE AREAS IDENTIFIED IN THE REMEDIAL INVESTIGATION WHICH WARRANT REMEDIAL ACTION, AND OF ALL ALTERNATIVES DEVELOPED BY EPA IN THE FEASIBILITY STUDY AND THE ALTERNATIVE DEVELOPED BY THE SITE RECEIVER IN THE ADDENDUM TO THE FEASIBILITY STUDY, THE SITE RECEIVER'S METHANE GAS GENERATION/RECOVERY ALTERNATIVE CAN BE IMPLEMENTED AT THE MOYER LANDFILL SITE. THIS PHASED ALTERNATIVE WILL MEET THE SUPERFUND GOALS OF MINIMIZING PRESENT AND FUTURE MIGRATION OF HAZARDOUS SUBSTANCES AND PROTECT HUMAN HEALTH AND THE ENVIRONMENT, WHILE ALSO ATTAINING ALL APPLICABLE AND RELEVANT FEDERAL PUBLIC HEALTH AND ENVIRONMENTAL STANDARDS, GUIDANCES AND ADVISORIES AT THE POINT OF CLOSURE (10 TO 20 YEARS). SPECIFICALLY THIS OPTION PROPOSES;
- SOIL COVER WITH A PERMEABILITY OF 10-4/10-5 CM/SEC
- EROSION AND SEDIMENTATION CONTROL MEASURES
- SURFACE WATER DIVERSION
- LEACHATE COLLECTION, TREATMENT AND DISCHARGE
- METHANE GAS RECOVERY AND SALE
- SECURITY/FENCING MEASURES
- GROUND WATER MONITORING
- ALL CLOSURE ACTIVITIES IN COMPLIANCE WITH RCRA AT THE CONCLUSION OF GAS GENERATION PHASE (10 TO 20 YEARS).

THIS ALTERNATIVE CONTEMPLATES BROAD REMEDIAL WORK AND ITS IMPLEMENTATION WILL DEPEND UPON THE SUCCESS OF THE GAS GENERATION/RECOVERY PROGRAM AND THE CONTRIBUTIONS FROM GENERATORS AND OTHER POTENTIALLY RESPONSIBLE PARTIES (PRPS). IF NEGOTIATIONS WITH THE PRPS FAIL AND/OR THE METHANE GAS ALTERNATIVE FAILS, EPA AND PADER RECOMMEND REMEDIAL ACTION ALTERNATIVE 4.2. THIS ALTERNATIVE IS THE COST-EFFECTIVE REMEDY AND WILL SATISFY AS WELL ALL OF THE CONTAMINATION AND MIGRATION OBJECTIVES IDENTIFIED IN THE REMEDIAL INVESTIGATION. SPECIFICALLY THIS OPTION PROPOSES;
- MISCELLANEOUS WORK PREPARATORY TO INSTALLATIONS OF RCRA CAP; GRADING, FLATTENING OF STEEP SLOPES, RETAINING WALLS AND INSTALLATIONS OF RIP-RAP AT AREAS THAT ARE MOST LIKELY TO BE ERODED.
- GAS VENTING AND GAS MONITORING.
- SURFACE WATER COLLECTION AND DISCHARGE TO SKIPPACK CREEK.
- LEACHATE COLLECTION AND TREATMENT THAT WILL MEET THE 10-6 RISK LEVEL IN THE GROUND WATER AND DISCHARGE REQUIREMENTS IN THE STREAM.
- OPERATION AND MAINTENANCE; GROUND AND SURFACE WATER MONITORING, MAINTENANCE OF THE CAP AND TREATMENT OF LEACHATE.
