equivalent of each unique building material sample to the whole. If the analytical

result is at or above the hazardous waste threshold (currently 5 PPM for lead) the

waste stream is a classified hazardous waste, and must be disposed of as such. If

the result is below the threshold, the waste stream is non- hazardous and can also

be disposed of as such. The only other decision to make is whether to have the

contractor repair the sample locations. Due to the requirements of this type of

test, it is difficult and expensive to repair sample locations. For this reason, it is

advisable to perform this sampling when people are removed from the building.

Determining the waste stream composition and classification during pre-design

provides the project Contractor the ability to control the amount of each waste to

be generated should the TCLP test identify the composite waste stream as

hazardous. With the TCLP test results available, the contractor can separate

hazardous components from non- hazardous components as these materials are

being generated and thus reduce the overall amount to be disposed as hazardous

waste. This process can save considerable cost. Typically, a whole building

demolition generates non-hazardous waste, but individual component removal

during a renovation, as opposed to a demolition, can generate hazardous waste.

Asbestos

The Contractor shall perform asbestos-containing material waste stream assessment and

characterization to determine if the asbestos containing waste streams will be considered

regulated or non-regulated under Federal or state NESHAP requir ements. The Contractor shall

estimate the quantity (e.g., the square or linear feet) of each building component sampled for the

presence of asbestos. The Contractor shall estimate the volume of debris or waste potentially

requiring disposal under the asb estos NESHAP requirements. Information gathered in the visual

examination shall be recorded in the field notes that will then be submitted as an attachment to

the Survey Report.

Lead

The Contractor shall determine if waste to be generated as a result of the demolition/renovation

or remodeling work will be characterized as hazardous or non-hazardous waste under Federal or

state RCRA requirements. This shall be accomplished by estimating the quantity (e.g., the

square or linear feet) of each building component (See Table B-4: Typical Building Materials

Comprising a Toxicity Characteristic Leaching Procedure (TCLP) Sample); the total volume of

all building component materials comprising the waste stream; and the percent of each building

material compone nt in the waste stream to be generated. Samples of each building material

component shall be sized in the same percentage found in the total waste stream, and shall be

sent in the same proportion to an NLLAP recognized laboratory for analysis. The Contractor

shall assure the laboratory performs the Toxicity Characteristic Leaching Procedure (TCLP) test
