[CPEO-BIF] New Jersey guidance on concrete recycling

[Lenny Siegel <lsiegel@cpeo.org>]

[The recycling of contaminated demolition debris appears to be a 
significant problem in the Northeast, and perhaps elsewhere in the 
country. This new New Jersey guidance document appears to be a major 
step in the right direction, but I invite comments from people more 
familiar with the issue. Is the guidance strong enough to make a 
difference? - LS]

 	

SRWM Solid & Hazardous Waste Program
The New Jersey Department of Environmental Protection
Site Remediation and Waste Management Program
Guidance for the Sampling and Analysis of Concrete
Designated for Recycling
(Updated February 20, 2007)

I. Overview:

The New Jersey Department of Environmental Protection (Department or 
NJDEP) is requiring the characterization, preferably by in situ 
predemolition sampling, or post-demolition sampling, by analysis of 
concrete and post-demolition concrete-processing fines at all New Jersey 
demolition and construction sites that have the Department’s Site 
Remediation and Waste Management Program’s (SRWMP) oversight at a 
contaminated site when the concrete is designated for: 1) recycling 
pursuant to N.J.A.C. 7:26A et seq.; or, 2) beneficial use pursuant to 
N.J.A.C. 7:26-1.7(g), rather than disposal as solid waste. This 
characterization requirement applies to demolished buildings, concrete 
roadways and related structures such as, but not limited to, sidewalks 
and curbing. The Department is taking this step to ensure that the 
concrete entering the State’s concrete recycling system is clean and 
will not contaminate otherwise clean sites.

The Sampling and Analysis Protocol outlined below is for certain 
contaminants that the Department recognizes may be found in concrete 
from contaminated sites. Only uncontaminated concrete will normally 
qualify for unrestricted recycling, while some minimally contaminated 
concrete or concrete fines may qualify for beneficial uses but only with 
Department approval.

For example, asphalt-contaminated concrete or concrete mixed with soils 
may meet beneficial use requirements for certain conditional uses at 
roadways. No sampling of the concrete from a site is required under this 
guidance if the property owner chooses to dispose of all of the material 
as solid waste. Note that Department approval pursuant to N.J.A.C. 
7:26-1.7(g)8 is required for the beneficial use of materials out of 
state, which may require sampling and analysis of the material to meet 
the receiving State’s requirements.
