Abstract:  THE LOVE CANAL SITE IS AN INACTIVE HAZARDOUS WASTE SITE LOCATED IN NIAGARA FALLS, NEW YORK. THE 19-ACRE 93RD STREET SCHOOL SITE, ONE OF SEVERAL OPERABLE UNITS FOR THE LOVE CANAL SUPERFUND SITE, IS THE FOCUS OF THIS RECORD OF DECISION (ROD). THIS SUBSITE IS LOCATED LESS THAN ONE MILE NORTHWEST OF THE LOVE CANAL DISPOSAL AREA AND IS WITHIN THE LOVE CANAL EMERGENCY DECLARATION AREA. SITE FEATURES INCLUDE THE 93RD STREET SCHOOL AND ADJACENT VACANT LAND, AND THE SITE IS BORDERED BY BERGHOLTZ CREEK TO THE NORTH AND RESIDENTIAL PROPERTIES TO THE EAST, WEST, AND SOUTH. FROM 1942 TO 1953, HOOKER CHEMICALS AND PLASTICS CORPORATION (NOW OCCIDENTAL CHEMICAL CORPORATION) DISPOSED OF OVER 21,000 TONS OF VARIOUS CHEMICALS INCLUDING DIOXIN-TAINTED TRICHLOROPHENOLS AT THE LOVE CANAL SITE. IN 1950, AFTER THE SITE WAS DEEDED TO THE CITY OF NIAGARA FALLS BOARD OF EDUCATION, THE 93RD STREET SCHOOL WAS BUILT. IN 1954, A SECOND SCHOOL, THE 99TH STREET SCHOOL, WAS BUILT ADJACENT TO THE MID-PORTION OF THE CANAL. BEFORE CONSTRUCTION OF THE 93RD STREET SCHOOL, A DRAINAGE SWALE HAD CROSSED THE SITE. IN 1954, THE SITE WAS GRADED TO ITS PRESENT CONTOURS WITH APPROXIMATELY 3,000 CUBIC YARDS OF FILL MATERIALS INCLUDING FILL FROM THE 99TH STREET SCHOOL. THE FILL MATERIAL IS REPORTED TO CONTAIN FLY ASH AND BHC (A PESTICIDE) WASTE. DURING THE MID-1970'S, CONTAMINATED LEACHATE MIGRATED TO THE SURFACE OF THE CANAL, TO SOME RESIDENTIAL BASEMENTS ADJACENT TO THE CANAL, AND THROUGH SEWERS TO AREA CREEKS. THOSE HOMES HAVE BEEN DEMOLISHED, AND THE SEWERS AND CREEKS IN THE LOVE CANAL EMERGENCY DECLARATION AREA HAVE BEEN REMEDIATED. IN 1980, THE 93RD STREET SCHOOL WAS CLOSED BECAUSE OF PUBLIC HEALTH CONCERNS RELATED TO THE POTENTIALLY CONTAMINATED FILL MATERIAL. INVESTIGATIONS CONDUCTED IN 1988 REVEALED THE PRESENCE OF VOCS, OTHER ORGANICS, AND METALS IN THE SOIL. DURING PREVIOUS INVESTIGATIONS, IT WAS DETERMINED THAT LOW LEVEL CONTAMINATION PRESENT IN THE GROUND WATER COMPARED TO THE GROUND WATER QUALITY IN THE AREA AND DID NOT POSE AN EXPOSURE THREAT TO THE CONCERNED POPULATION. A 1988 ROD ADDRESSED SOURCE CONTROL THROUGH EXCAVATING AND SOLIDIFYING/STABILIZING THE EXCAVATED MATERIAL, PLACING THE MATERIAL INTO THE SAME UNIT, AND CAPPING WITH A LOW PERMEABILITY SOIL COVER. THE REMEDIAL ACTION WAS NOT IMPLEMENTED AND HAS BEEN REEVALUATED IN LIGHT OF THE NIAGARA FALLS BOARD OF EDUCATION'S 1989 PLAN TO RESTORE THE 93RD STREET SCHOOL AS AN EDUCATIONAL FACILITY AND TO ADDRESS OBJECTIONS TO REOPENING THE SCHOOL IF CONTAMINATED SOIL REMAINS ONSITE. THIS ROD AMENDS THE 1988 ROD, AND ADDRESSES FINAL REMEDIATION OF ONSITE CONTAMINATED SOIL THROUGH EXCAVATION AND OFFSITE DISPOSAL. THE PRIMARY CONTAMINANTS OF CONCERN AFFECTING THE SOIL ARE VOCS INCLUDING TOLUENE AND XYLENES; OTHER ORGANICS INCLUDING PAHS AND PESTICIDES; AND METALS INCLUDING ARSENIC, CHROMIUM, AND LEAD.

THE AMENDED REMEDIAL ACTION FOR THIS SITE INCLUDES EXCAVATING AND DISPOSING OF OFFSITE 7,000 CUBIC YARDS OF CONTAMINATED SOIL FROM HOT SPOT AREAS; BACKFILLING EXCAVATED AREAS WITH SITE SOIL OF LOWER CONTAMINATION; AND CAPPING AND REGRADING THE AREA WITH FILL MATERIAL. THE ESTIMATED PRESENT WORTH COST FOR THIS AMENDED REMEDIAL ACTION IS $2,250,000, WHICH DOES NOT INCLUDE O&M COSTS.

PERFORMANCE STANDARDS OR GOALS; SOIL ACTION LEVELS WERE NOT PROVIDED. GROUND WATER CLEAN-UP GOALS WERE WAIVED DUE TO TECHNICAL IMPRACTICABILITY.
 
Remedy:  THE REMEDY PRESENTED IN THIS DOCUMENT ADDRESSES THE OFF-SITE DISPOSAL OF THE CONTAMINATED SOILS AT THE 93RD STREET SCHOOL SITE.

THE MAJOR COMPONENTS OF THE SELECTED REMEDY INCLUDE;
* EXCAVATION AND OFF-SITE DISPOSAL OF APPROXIMATELY 7000 CUBIC YARDS OF THE CONTAMINATED MATERIAL FROM THE HOT-SPOT AREAS, WHICH MAY BE REUSED OR RECYCLED OFF-SITE AS COVER AND/OR FILL MATERIAL.
* BACKFILLING THE EXCAVATED AREA WITH SITE SOILS FROM AREAS OF LOWER CONTAMINATION, COVERING WITH APPROXIMATELY ONE FOOT OF SUITABLE FILL MATERIAL, AND REGRADING TO CONTOURS FOR PROPER DRAINAGE.

THE REMEDIATION OF SITE SOILS, WHICH ARE CONSIDERED THE PRINCIPLE THREAT TO THE SITE, WILL PREVENT ANY POTENTIAL GROUNDWATER CONTAMINATION AND REDUCE THE RISKS ASSOCIATED WITH EXPOSURE TO THE CONTAMINATED SOIL.
