Abstract:  THE 20-ACRE HEBELKA AUTO SALVAGE YARD SITE IS AN AUTOMOBILE JUNKYARD IN WEISENBERG TOWNSHIP, LEHIGH COUNTY, PENNSYLVANIA. LAND USE IN THE AREA IS PREDOMINANTLY AGRICULTURAL, WITH FOUR RESIDENTIAL PROPERTIES CLOSE TO THE SITE. THE SITE IS LOCATED WITHIN THE HEADWATERS OF THE IRON RUN SUBDRAINAGE BASIN. FROM 1958 TO 1979, AND AGAIN FROM 1989 TO PRESENT, THE SITE WAS USED AS AN AUTOMOBILE JUNKYARD AND FOR SALVAGE OPERATIONS. SCRAP IRON WAS RECOVERED FROM USED STORAGE TANKS THAT WERE DISPOSED ONSITE, SOME OF WHICH STILL CONTAINED ORGANIC CHEMICALS. IN ADDITION, DURING THE PAST 10 TO 15 YEARS, APPROXIMATELY 1,000 CUBIC YARDS OF USED BATTERY CASINGS HAVE BEEN DISPOSED OF ONSITE IN TWO PILES, ALONG WITH EMPTY STORAGE TANKS AND DRUMS, JUNKED CARS, AND MISCELLANEOUS SCRAP METAL. IN 1985, EPA INVESTIGATIONS IDENTIFIED ELEVATED LEVELS OF LEAD AND CHROMIUM IN SOIL AND SEDIMENT. A 1989 RECORD OF DECISION (ROD) ADDRESSED REMEDIATION OF SITE AREAS WITH LEAD CONCENTRATIONS EXCEEDING 560 MG/KG IN SOIL, AS WELL AS THE PILES OF SCRAP BATTERY CASINGS ABOVE THESE SOIL AREAS. THE ROD ALSO PROVIDED FOR REMOVAL AND RECYCLING OF THE BATTERY CASINGS, AND EXCAVATION AND TREATMENT OF SOIL USING CEMENT OR LIME-BASED FIXATION PROCESSES. THIS ROD WAS DEVELOPED TO ADDRESS SOIL OUTSIDE OF THE HIGH LEAD CONCENTRATION AREAS, GROUND WATER, SURFACE WATER, AND AIR. HOWEVER, BECAUSE SITE INVESTIGATIONS HAVE FOUND NO EVIDENCE OF CONTAMINATION IN THE MEDIA ADDRESSED IN THIS ROD, THERE ARE NO CONTAMINANTS OF CONCERN.

THE SELECTED REMEDIAL ACTION FOR THIS SITE INCLUDES NO FURTHER ACTION OTHER THAN MONITORING GROUND WATER AND SURFACE WATER OF IRON RUN ANNUALLY, AND A BIOASSESSMENT OF THE CREEK. THE ESTIMATED PRESENT WORTH COST FOR THIS REMEDIAL ACTION IS $66,300, WHICH INCLUDES AN ANNUAL O&M COST OF $4,500 FOR 30 YEARS. THE COST FOR THE FOLLOW-UP BIOASSESSMENT IS $125,000.

PERFORMANCE STANDARDS OR GOALS; NOT APPLICABLE.
 
Remedy:  THIS OPERABLE UNIT IS THE SECOND OF TWO OPERABLE UNITS PLANNED FOR THE SITE. THE FIRST OPERABLE UNIT (OU1) ADDRESSES THE REMOVAL OF LEAD IN BATTERY CASINGS AND SOIL REMEDIATION OF SOILS WITH LEAD CONCENTRATIONS ABOVE 560 MG/KG AND COMPRISES THE FOLLOWING COMPONENTS;
* REMOVAL AND RECYCLING OF APPROPRIATELY 1,000 CUBIC YARDS OF BATTERY CASINGS AND
* TREATMENT OF LEAD-CONTAMINATED SOIL LESS THAN EXCAVATION OF APPROXIMATELY 2,000 CUBIC YARDS OF LEAD CONTAMINATED SOIL (LEAD CONCENTRATIONS OVER 500 PARTS PER MILLION), LESS THAN FIXATION OF EXCAVATED SOIL UTILIZING A CEMENT- OR LIME-BASE FIXATION PROCESS LESS THAN DEPOSITION OF THE MIXED MATERIAL IN THE LANDFILL THAT THE COMMONWEALTH HAS PERMITTED TO ACCEPT.

OU2 ADDRESSES SOILS OUTSIDE OF THE HIGH LEAD CONCENTRATION AREAS, AIR, GROUNDWATER, AND SURFACE WATER IN THE VICINITY OF THE SITE. EPA HAS DETERMINED THAT NO FURTHER RESPONSE ACTION IS NECESSARY BEYOND THAT SELECTED FOR OU1. EPA WILL CONTINUE TO CONDUCT MONITORING AT THE SITE ON AN ANNUAL BASIS, INCLUDING CONDUCTING A BIOASSESSMENT SURVEY TO VERIFY THAT NO UNACCEPTABLE EXPOSURE TO RISKS POSED BY CONDITIONS AT THE SITE OCCUR IN THE FUTURE.
