The presence of the FAP in the soils used in this study at rates up to 5% w/w resulted in elevated levels of Cu, Mn, Ni, AS, and Co in the TCLP
According to the Boston-based Northeast Waste Management Officials' Association (NEWMOA), some manufacturers use additives to influence the TCLP
test and mask the true mercury content of the lamp.
CERL again performed TCLP
for lead on the two samples with highest total concentrations (160 and 130 mg/kg).
All GE two-, three-, and four-foot T8 linear fluorescent lamps are now Ecolux[R] products, which exceed the TCLP
standards set by the EPA.
Alto lamp technology -- which has been expanded to more than 85% of Philips' line -- ensures TCLP
compliance by reducing mercury at the source by an average of 80%.
The compounds, shown in table 3, were tested for lead extractability via the EPA acetic acid extraction referred to as the Toxic Characteristic Leaching Procedure (TCLP
Many stormwater detention basin and sediment trap sediments that now just pass the TCLP
test (and therefore are classified as a non-hazardous waste) could be classified as hazardous wastes if the TCLP
allowable lead limit is adjusted downward.
Most MWC ash (80 to 99 percent) is bottom ash, which typically meets the environmental standards for the toxicity characteristic leaching procedure (TCLP
* The TCLP
(Toxic Characteristic Leaching Procedure), a process for determining hazardous wastes in the federal Resource Conservation and Recovery Act (RCRA, administered by EPA), goes a step further adding silver to the list in ANSI Z66.1.
This "Toxicity Characteristic Leaching Procedure" (TCLP
) requires that a number of potentially small generators of hazardous waste conduct a lab test on various materials used in their workplaces.
The new definition calls for use of a new method to identify hazardous waste materials - the Toxic Characteristic Leaching Procedure (TCLP
(2) Leached [Pb.sup.2+] concentration after the TCLP
test decreased with the increase of the alkaline residue content and curing time, while increased with the increase of the initial [Pb.sup.2+] concentration in the specimen.
