PERFORMANCE STANDARDS
The following table provides the performance objectives that were established for the SCS Site
incinerator in the September 1988 ROD:
Incinerator Performance Objectives

Performance Criteria
Principal Organic Hazardous Constituent
≥ 99.99%
(POHC) destruction removal efficiency (DRE)

Hydrochloric Acid ( HCl) Emissions
≤30 nanograms/dry standard cubic meter (ng/dscm) @ 7% O2
Total Dioxins and Furans Emissions
≤300 parts per million volume (ppmv) @ 7% O2 (daily
NOx Emissions
average)
≤100 ppmv @ 7% O2 (hourly rolling average)

<0.27 g/sec
Cr+6
<0.04 g/sec
Cr
<0.12 g/sec

Fly ash and bottom ash were analyzed for metals using the toxicity characteristic leaching
procedure (TCLP). The results were compared to the Texas drinking water standards listed in
the table below. Ash meeting these standards could be backfilled on-site without restriction.
Ash failing these standards, but with TCLP concentrations less than 25 times the drinking water
standards, could be returned to the site as fill material but could not be placed below 553 feet
mean sea level (8 feet above the average water table). As specified in the 1988 ROD, treated soil
with TCLP concentrations greater than 25 times the drinking water standard required
stabilization prior to backfill.
