Abstract:  THE WESTLINE SITE IS LOCATED IN WESTLINE, LAFAYETTE TOWNSHIP, MCKEAN COUNTY, PA. THE SITE, ENCOMPASSING APPROXIMATELY 40 ACRES, IS BORDERED BY KINZUA CREEK TO THE SOUTH, TURNIP RUN TO THE EAST, AND A WETLAND AREA TO THE WEST. FOR THE PURPOSE OF THIS INVESTIGATION, THE NORTHERN BORDER EXTENDS 250 FEET NORTH OF THE FORMER CHEMICAL PLANT FOUNDATION. LOCATED AT THE CENTER OF THE SITE IS A POPULAR LANDMARK, THE WESTLINE INN. BEGINNING IN 1901, THE DAY CHEMICAL COMPANY, CONVERTED LUMBER INTO CHARCOAL, METHANE AND ACETIC ACID. THE PLANT CHANGED OWNERS THREE TIMES BEFORE EQUIPMENT DETERIORATION AND DECLINING PROFITS FORCED ITS CLOSURE IN 1952. SEVERAL TAR-LIKE DEPOSITS FROM THE WOOD CHEMICAL PROCESSING OPERATIONS REMAIN ONSITE. THE LARGEST DEPOSIT WAS EXCAVATED IN SEPTEMBER OF 1983 BY THE REMOVAL ACTION IMPLEMENTED BY THE EPA. ANOTHER TAR DEPOSIT, APPROXIMATELY 6 INCHES DEEP AND 1,500 SQUARE FEET IN TOTAL AREA, STILL EXISTS. SEVERAL SMALLER TAR DEPOSITS ARE LOCATED INTERMITTENTLY IN THE LOW-LYING AREAS OF THE GROUND SURFACE. TAR IS ALSO SEEN ALONG THE BANKS OF AN UNNAMED TRIBUTARY. THE FS HAS ESTIMATED A TOTAL OF 710 CUBIC YARDS OF TAR AND TAR SOILS ONSITE. DURING THE INITIAL EPA SITE INSPECTION IN JULY OF 1982, A SAMPLE OF WASTE MATERIAL WAS COLLECTED FROM THE SEEPAGE AND ANALYZED FOR PRIORITY POLLUTANTS. EIGHTEEN TENTATIVELY IDENTIFIED COMPOUNDS WERE DETECTED. IN MARCH 1986, A SECOND WOOD TAR SAMPLE WAS COLLECTED TO VERIFY THE PRESENCE OR ABSENCE OF POLYNUCLEAR AROMATIC HYDROCARBONS (PAH). THE PRIMARY CONTAMINANTS OF CONCERN INCLUDE PHENOL, 2,4-DIMETHYLPHENOL, AND PAH COMPOUNDS.

THE SELECTED REMEDIAL ACTION FOR THIS SITE INCLUDES; EXCAVATION OF ALL WOOD TAR DEPOSITS AND SUBSEQUENT HAULING OF THESE WASTES TO A PERMITTED OFFSITE FACILITY; BACKFILLING OF THE EXCAVATED AREAS WITH CLEAN SOIL AND VEGETATION; INCINERATION OF EXCAVATED DEPOSITS WITH A HIGH HEATING VALUE AND LOW ASH CONTENT TECHNIQUE; GROUND WATER VERIFICATION STUDY; AND AIR MONITORING. THE BASELINE CAPITAL COSTS FOR THIS REMEDIAL ACTION IS $744,000. O&M WILL NOT BE REQUIRED FOR THE AREAS WHERE TAR WILL BE EXCAVATED, BUT PERIODIC INSPECTION OF THE AREAS TO ASSURE THE REMEDY IS EFFECTIVE WILL BE NECESSARY. FOLLOWING THE GROUND WATER VERIFICATION STUDY, O&M WILL BE RECONSIDERED.
 
Remedy:  1. THE WASTE TAR WILL BE EXCAVATED FROM THE EXISTING PIT BEHIND THE WESTLINE CHURCH, FROM THE INTERSPERSED TAR DEPOSIT AREAS IN THE SOUTH AND SOUTH-WESTERN PORTIONS OF THE SITE ALONG KINZUA CREEK AND FROM THE BANKS OF THE UNNAMED TRIBUTARY. THE WASTE TARS WILL BE INCINERATED OFFSITE.
2. BACKFILLING THE EXCAVATED AREAS WITH CLEAN SOIL AND REVEGETATING WILL BE REQUIRED.
3. THE TAR DEPOSITS WILL BE EXCAVATED TO THE SOIL LEVEL. SAMPLING AND ANALYSIS WILL BE CONDUCTED DURING EXCAVATION TO BE SURE CONTAMINATED SOILS ARE REMOVED TO A LEVEL EQUIVALENT TO A 10-4 CANCER RISK FOR DIRECT CONTACT WITH SOILS OVER A 20 YEAR PERIOD. THIS LEVEL IS CHOSEN BECAUSE IT IS SIMILAR TO SOME OF THE BACKGROUND LEVELS FOUND IN THE COMMUNITY. THE REMOVAL OF THE TAR DEPOSITS WILL ALSO INSURE THAT THE REMAINING PAHS IN SOILS WILL NOT LEACH FROM THE SOILS TO THE GROUND WATER IN CONCENTRATIONS THAT WILL EXCEED LEVELS EQUIVALENT TO A 10-6 CANCER RISK FOR INGESTION OF GROUND WATER.
4. AS A SAFETY PRECAUTION, AIR MONITORING WILL BE CONDUCTED DURING EXCAVATION.
5. PACKAGING OF THE WASTE TAR MATERIALS WILL BE COMPATIBLE WITH INCINERATOR FACILITY REQUIREMENTS.
6. TRANSPORTATION AND DISPOSAL OF THE WASTE TAR MATERIALS WILL BE CONDUCTED IN ACCORDANCE WITH STATE AND FEDERAL DEPARTMENT OF TRANSPORTATION (DOT) REQUIREMENTS, INCLUDING APPLICABLE RESOURCE CONSERVATION AND RECOVERY ACT (RCRA) REQUIREMENTS; THE MATERIAL WILL BE TRANSPORTED TO A RCRA PERMITTED FACILITY FOR INCINERATION.
7. A GROUND WATER VERIFICATION STUDY WILL BE CONDUCTED TO DETERMINE IF THE CONTAMINATION AT MONITORING WELL MW-006 IS PRESENT DOWNGRADIENT OR IN HIGHER CONCENTRATIONS IN THE UPPER MOST ZONE OF GROUND WATER. SPECIFICS OF THE NUMBER AND WELL LOCATIONS WILL BE DETERMINED IN THE NEXT STAGE FOR DESIGN OF THE REMEDIAL ACTION.
