DRAFT/MODIFICATION OF HOPE TAYLOR'S CRITERIA OF JUNE 20, 1995
TECHNOLOGY SCREENING: REMEDIATION OF THE
WARREN COUNTY PCB LANDFILL
DRAFT REPORT, July 5, 1995
1) Community acceptability is to be based on consideration of four factors: 1-community
perceived risk offered by technology; 2 -Potential for harm to human health; 3 -Actual or
potential environmental releases or emissions; 4 -Consideration of impact on property values.
This criterion is a measure of the community's over all perception of technology, after having a
presentation of descriptions and evaluations of the technology as well as ask questions of technical
advisors. The community's assessment of acceptability will be prominently included with any
distribution of this technology screening information and will be extremely important in
selection of actual pilot study and full remediation vendors. (Suggested ratings: 4 -
outstanding, 3 -satisfactory; 2 -marginally acceptable; 1 unacceptable)
2) Extent of prior experience with this technology on soils at similar sites. (Rating
based on the number of sites with PCB or dioxin-contaminated soils which have completed
pilot or full-scale projects with this technology: 4 -more than five sites; 3 three to five
sites; 2-one to two sites; 1 -no sites using this technology.)
3) Short term safety and effectiveness. Includes potential for worker and community
exposure due to planned and unplanned releases (excavation, gaseous emissions, solvents)
during operation. (Rating: 4 -in situ and well-contained process or "closed loop" with
essentially no chance of releases; 3 -technology demonstrates very low release levels
within regulatory limits; 2 -some releases documented with technical improvements
currently available; 1 -uncontrolled release possible.)
4) Long term effectiveness. Reduction of toxicity or volume of toxic contaminants.
(Rating: 4 -demonstrated ability to detoxify contaminants to at least 99% removal level;
3 -demonstrated ability to detoxify contaminants to at least 95 % removal level, or to
reduce volume of contaminated soils to less than 30 % of original volume as part of a
"treatment train" , with greater than 95 % removal from remaining fraction; 2 -ability to
detoxify or concentrate contaminants to 90 % level or to higher levels under limited
conditions; 1 -technology generally not effective on contaminants and under conditions
at the Warren County Landfill.)
5) Generation of residuals and ability to handle on-site. (Rating: 4 -no residuals or
completely treatable on-site; 3 -small volume of residuals, predominantly treatable on-site,
2 -moderate volume of residuals, mostly treatable on site at added expense; 1 -large
volume of incompletely detoxified residuals.)
6) Projected duration of full-scale treatment. (Rating: 4 -less than six months; 3 six
months to one year; 2 -one to two years; 1 -longer than two years.)
7) Availability of pilot scale treatment. (Rating: 4 -available to start immediately; 3
available to start within three months; 2 -available within six months; 1 -longer than six
months or unknown.)
8) Implementability of this technology at Warren County PCB Landfill. Number of
vendors available, technical impediments, extent of infrastructure requirements. (Rating:
4 -more than three vendors available, no major technical problems anticipated, system
largely self-contained; 3 -two to three vendors, technical problems are soluble with
minimal expense and time, few unique requirements for infrastructure support; 2 -one
vendor available, technical problems may delay or increase costs up to 25 % ; significant
unique infrastructure support needed for this technology; 1 -no vendors available, major
technical problems, infrastructure requirements too expensive or unobtainable at this site.)
9) Estimated cost per cubic yard of contaminated soil treated. (Rating: the projected
cost range will be given and the mid-point of that range will be rated as 4 -less than $100
cubic yard; 3 -$100 to $300 per cubic yard; 2 -$300-$500 per cubic yard; 1 -$300-$500
per cubic yard; 1 -greater than $500 per cubic yard.)
