Abstract:  THE 2-ACRE BETTER BRITE PLATING CHROME & ZINC SITE IS COMPOSED OF TWO PLATING FACILITIES IN DE PERE, BROWN COUNTY, WISCONSIN. THE SITE INCLUDES THE 1.5-ACRE CHROME SHOP AND THE 0.5-ACRE ZINC SHOP, WHICH ARE LOCATED APPROXIMATELY 0.5 MILES APART. BECAUSE OF THEIR PROXIMITY AND RELATED BACKGROUNDS, THE TWO SITES WERE JOINTLY NOMINATED TO THE NATIONAL PRIORITY LIST AND ARE ADDRESSED AS A SINGLE SITE IN THIS RECORD OF DECISION (ROD). LAND USE IN THE AREA IS PREDOMINANTLY RESIDENTIAL AND COMMERCIAL, WITH A WETLANDS LOCATED APPROXIMATELY ONE-QUARTER MILE FROM THE SITE. THE ESTIMATED 15,000 AREA RESIDENTS USE THE MUNICIPAL WELLS DRAWING FROM THE DEEP AQUIFER AS A DRINKING WATER SUPPLY. A MUNICIPAL WELL LOCATED APPROXIMATELY 250 FEET FROM THE SITE IS THOUGHT TO INFLUENCE THE GROUND WATER FLOW IN THE CONTAMINATED SHALLOW AQUIFER, BUT IMPACTS HAVE NOT BEEN OBSERVED IN THE MUNICIPAL WELL ONSITE. FROM 1963 TO THE EARLY 1970'S, THE ZINC SHOP PRIMARILY PLATED CHROME SWITCHING LATER TO ZINC. THE ZINC SHOP HAS A LONG HISTORY OF IMPROPER OPERATIONAL PROCEDURES AND SPILLS INTO THE SURROUNDING SOIL. WASTEWATER AND/OR PLATING SOLUTIONS ROUTINELY LEAKED BETWEEN THE FLOOR AND SILL PLATE OF THE BUILDING. REPORTEDLY UNDERGROUND VERTICAL PLATING TANKS WERE USED EARLY ON. THE CHROME SHOP BEGAN CHROME PLATING OPERATIONS DURING THE EARLY 1970'S USING SEVERAL ABOVE-GROUND TANKS AND FOUR BURIED VERTICAL TANKS IN THE PLATING PROCESS. IN 1978 AND 1979, THE CHROME SHOP WAS FOUND TO BE RESPONSIBLE FOR SURFACE SPILLS, WHICH RESULTED IN CONSTRUCTION OF A SHALLOW GROUND WATER EXTRACTION SYSTEM AROUND A PORTION OF THE SITE. LATER, IT WAS DETERMINED THAT THE UNDERGROUND PLATING TANKS FROM THE CHROME SHOP HAD LEAKED AN UNKNOWN AMOUNT OF PLATING SOLUTION AND VOCS INTO THE ONSITE GROUND WATER. CONSEQUENTLY, IN 1985, THE OWNER OF THE CHROME SHOP FILED FOR BANKRUPTCY AND OPERATIONS CEASED IN 1986. IN 1987, THE STATE INSTALLED GROUND WATER MONITORING WELLS AT THE SITE, WHICH IDENTIFIED CONTAMINATION BY METALS AND VOCS IN SOIL AND GROUND WATER. IN 1989, THE ZINC SHOP CLOSED, AND A PRIVATE CONTRACTOR REMOVED THE BUILDING THAT HOUSED THE CHROME SHOP. THE STATE CONSTRUCTED A CLAY CAP AND FENCED AROUND THE AREA OF HIGHEST SOIL CONTAMINATION. IN 1990, THE ZINC SHOP OWNER FAILED TO COMPLY WITH AN ADMINISTRATIVE ORDER TO CONDUCT CLEAN-UP ACTIVITIES. SUBSEQUENTLY, EPA PERFORMED AN EMERGENCY REMOVAL ACTION, WHICH INCLUDED SHIPPING 350_CUBIC YARDS OF HAZARDOUS AND SOLID WASTE OFFSITE AND CONSTRUCTING A GROUND WATER COLLECTION SUMP. GROUND WATER IS COLLECTED, STORED TEMPORARILY, AND TREATED ONSITE. THE RESIDUAL CHROMIUM SLUDGE FROM THE GROUND WATER TREATMENT IS SENT OFFSITE FOR RECYCLING. LATER IN 1990, EPA PERFORMED AN ADDITIONAL EMERGENCY RESPONSE, AND PROVIDED FOR THE CONSTRUCTION OF A WASTEWATER PRETREATMENT SYSTEM AND AN EXTRACTION SYSTEM TO COLLECT AND PRETREAT SHALLOW GROUND WATER PRIOR TO DISCHARGE OFFSITE TO THE DE PERE WASTEWATER SYSTEM. THIS ROD ADDRESSES OPERABLE UNIT 1, CONTAMINATED GROUND WATER AND SURFACE WATER, AS AN INTERIM ACTION. FUTURE RODS WILL ADDRESS REMAINING SOIL AND GROUND WATER CONTAMINATION. THE PRIMARY CONTAMINANTS OF CONCERN AFFECTING THE GROUND WATER AND SURFACE WATER ARE VOCS INCLUDING 1,1,1-TCA AND 1,1-DCA; OTHER ORGANICS; AND METALS INCLUDING CHROMIUM, CYANIDE, AND LEAD.

THE SELECTED REMEDIAL ACTION FOR THIS INTERIM REMEDY INCLUDES CONTINUING AND EXPANDING THE CURRENT OPERATION OF THE GROUND WATER EXTRACTION SYSTEM AND PRETREATMENT FACILITY, WHICH WILL INCLUDE PRETREATMENT OF THE ADDITIONAL WATER COLLECTED BY THE SURFACE WATER AND GROUND WATER COLLECTION SYSTEMS, AND THE CHROME AND ZINC SHOPS, WITH DISCHARGE TO THE DE PERE WASTEWATER SYSTEM; IMPROVING SURFACE WATER DRAINAGE, AND CONSTRUCTING BERMS TO CONTROL SURFACE WATER RUNOFF AND TO PREVENT CONTAMINANT MIGRATION; INSTALLING MONITORING WELLS; FENCING BOTH SHOPS; AND APPLYING SIDING MATERIALS ON THE EXTERIOR OF THE BUILDING AT THE ZINC SHOP. THE ESTIMATED PRESENT WORTH COST FOR THIS REMEDIAL ACTION IS $500,000, WHICH INCLUDES AN ANNUAL O&M COST OF $60,000.

PERFORMANCE STANDARDS OR GOALS; ALL ARARS WILL BE MET DURING THE FINAL ACTION FOR THE SITE.
 
Remedy:  THIS INTERIM REMEDIAL ACTION IS THE FIRST OF TWO OR MORE OPERABLE UNITS FOR THE SITE. THIS OPERABLE UNIT ADDRESSES CONTAMINATION OF GROUNDWATER THROUGH TREATMENT, ENGINEERING CONTROLS AND LIMITING SITE ACCESS. SUBSEQUENT OPERABLE UNITS WILL CONTINUE TO ADDRESS CONTAMINATED SOILS AND GROUNDWATER THROUGH THE ONGOING REMEDIAL INVESTIGATION/FEASIBILITY STUDY (RI/FS).

THE MAJOR COMPONENTS OF THE SELECTED REMEDY INCLUDE;
* CONTINUED OPERATION OF THE EXISTING GROUNDWATER EXTRACTION AND PRETREATMENT FACILITY;
* CONSTRUCTION OF BERM(S) TO DIVERT THE FLOW OF SURFACE WATER;
* INSTALLATION OF AN ADDITIONAL EXTRACTION SYSTEM TO HELP ALLEVIATE PONDING AT THE CHROME SHOP;
* IMPROVEMENT OF EXISTING FENCES AT THE CHROME SHOP AND INSTALLATION OF FENCES AT THE ZINC SHOP;
* APPLICATION OF SIDING AND/OR DURABLE PLASTIC TO THE EXTERIOR OF THE BUILDING AT THE ZINC SHOP; AND
* INSTALLATION OF MONITORING WELLS TO PROVIDE INFORMATION CONCERNING FLOW DIRECTION AND CHEMISTRY OF THE GROUNDWATER.
