Superfund Record of Decision (EPA Region 2) Carroll and Dubies Sewage Disposal,211 Port Jervis, NY., August 24, 1998

摘要

The March 31, 1995 first operable unit (OU1) Record of Decision (ROD) (PB95-211u001e963802) called for the excavation, treatment and long-term on-site containment of 211u001econtaminated lagoon materials and soil. Supplemental sampling activities were 211u001econducted in March 1997 during the remedial design phase of the remedy. The 211u001eresults of the investigation confirm the findings of the previous investigations 211u001eregarding the types of wastes and contaminants present in the lagoons. The 211u001ebioslurry treatment of these wastes was not deemed to be practicable; it was 211u001edetermined that the contingency remedy should be implemented. It was determined 211u001ethat the waste in and surrounding each lagoon can be readily segregated into 211u001especific waste streams based on physical characteristics, making additional off-211u001esite treatment more cost-effective. The modified remedy expands the off-site 211u001etreatment and disposal component of the contingency remedy; more of the waste 211u001ewill be treated off-site. The contaminated materials targeted for remediation 211u001eremains the same.
