<strong>Regulatory</strong> <strong>Perspective</strong><br />

CURRENT REGULATIONS<br />
40 CFR Part 761<br />
Section 6(e) of the Toxic Substances Control Act<br />
of 1976 (TSCA) generally bans the manufacture,<br />
processing, distribution in commerce, and use of<br />
PCBs after 1978, but provides for exceptions<br />
based on an EPA finding of “no unreasonable<br />
risk of injury to health or the environment.”<br />
Most of the exceptions take the form of<br />
authorizations, which include conditions, such<br />
as location restrictions, repair restrictions, and<br />
concentration limits.<br />
1998 Amendments
<strong>Regulatory</strong> Considerations<br />
PCB regulations include owners and/or operators<br />
of PCB-contaminated property where the PCB<br />
contamination exceeds allowable concentrations<br />
under the regulations<br />
TSCA authority has not been delegated to any of<br />
the states, thus both EPA and state regulations<br />
will apply

Issues<br />
<br />
The use of PCBs in non-liquid manufactured building products<br />
at >/= 50 ppm is prohibited under TSCA.<br />
<br />
Manufactured products containing PCBs have been found in<br />
many buildings and structures<br />
Caulk typically contains PCBs at very high levels - %<br />
<br />
The PCBs in the caulk migrate to a limited extent to<br />
surrounding materials (air, soil, masonry).<br />
<br />
Typical renovation procedures can increase exposures to<br />
workers and building residents, including children.
PCBs in Building Materials<br />
Bulk Product Waste (761.62)<br />
examples: caulk, applied dried paints, varnishes, other<br />
similar coatings or sealants, Galbestos<br />
Performance-based disposal<br />
Disposal in Solid Waste Landfill<br />
Risk-based Disposal Approval<br />
Daily Cover/Roadbed
Source Removal<br />
PCB Bulk Product Waste<br />
Caulk removal<br />
–Strip out<br />
Paint removal<br />
–Abrasives<br />
–Chemicals<br />
–Hydroblast<br />
**761.62**
Adjacent Surfaces<br />
PCB Remediation Waste<br />
Grind/cut out areas<br />
of contamination<br />
beyond “source<br />
material”<br />
Encapsulate porous<br />
surfaces<br />
Clean non-porous<br />
** 40 CFR 761.61 **
Management in Place<br />
Not acceptable for PCB bulk product<br />
waste (§ 761.62)<br />
May be acceptable for surrounding<br />
materials (§ 761.61)<br />
Possible short-term interim measure<br />
– Consultation with EPA<br />
– Sampling may be required
Excluded PCB Products<br />
Must meet all criteria under § 761.3<br />
May be left in place without further<br />
restrictions/requirements<br />
State Requirements may require<br />
removal
PROJECT CONSIDERATIONS
Establish DQOs<br />
DATA QUALITY<br />
Analytical program with adequate QA/QC<br />
samples is critical<br />

Steps to Safe Renovation and Abatement of Buildings that have PCB-<br />
Containing Caulk<br />

EPA Recommendations<br />
For buildings built between 1950 and 1978<br />
– Minimize exposure (e.g. ventilation, cleaning)<br />
– Take care when renovating<br />
– Take care when abating<br />
If you think you may have a problem<br />
– Test for elevated air levels<br />
– Test for source of air contamination<br />
Evaluate duct systems<br />
