# SUPPLEMENTARY INFORMATION:

## I. General Information

                    This notice is directed to the public in general, and may be of interest to a wide range of stakeholders, including private citizens, federal, tribal, state and local governments, environmental consulting firms, industry representatives, environmental organizations and other public interest groups. Since others may also be interested, the Agency has not attempted to describe all the specific entities that may have interest in this notice. If you have any questions regarding the applicability of this action to a particular entity, consult the EPA personnel listed under                     **FOR FURTHER INFORMATION CONTACT**                    .                

                    The EPA is inviting the public to provide comments on a proposed reinterpretation of its position regarding PCB bulk product and PCB remediation waste under regulations promulgated at 40 CFR part 761. The EPA has opened the docket for public comment for 30 days after publication in the                     **Federal Register**                    . Details on how to provide comments to the docket are provided under                     **ADDRESSES**                    .                

## II. Background

EPA has received several questions from the regulated community regarding the disposal and cleanup requirements for PCB-contaminated building materials. The Toxic Substances Control Act (TSCA) regulations at 40 CFR 761 provide disposal and cleanup requirements for PCBs. The disposal and cleanup requirements for PCB-contaminated building material depend on whether the material is classified as PCB bulk product waste or PCB remediation waste.

Waste derived from caulk or paint containing PCBs at ≥ 50 parts per million (ppm) is defined as PCB bulk product waste in 40 CFR 761.3. The definition of PCB bulk product waste includes “non-liquid bulk wastes or debris from the demolition of buildings and other man-made structures manufactured, coated, or serviced with PCBs.” Other PCB bulk product wastes may include, but are not limited to, mastics, sealants, or adhesives containing PCBs at ≥ 50 ppm.

PCB remediation waste is defined as “waste containing PCBs as a result of a spill, release, or other unauthorized disposal * * *”, and leaching may be considered a release of PCBs.

The Agency proposes to reinterpret its position regarding the status of PCB-contaminated building materials under the definition of PCB bulk product waste and is seeking comment on this proposal. In association with this reinterpretation, EPA has identified several guidance documents that would be changed with this proposed reinterpretation if the Agency finalizes this proposal.

                    EPA believes that this proposed reinterpretation would allow for accelerated cleanups of PCB-contaminated building material by providing a more straightforward path for disposal pursuant to the regulations. Speeding up removal and disposal of the PCB-contaminated material is critical for reducing exposure potential, such as in schools or other locations where such PCB-contaminated building materials are currently in place. The current interpretation of these regulations applies different requirements to PCB-contaminated building materials than to the products                           ( print page 12295)                        that were originally manufactured with PCBs (e.g., paint or caulk). Labeling the building materials a different type of PCB waste than PCB bulk product waste (e.g., paint or caulk) can result in slower and more costly removal and disposal. This proposed reinterpretation maintains existing environmental and human health protections and removes unnecessary burdens to allow for more expedient cleanups, thus reducing potential exposures, for example, in schools and commercial buildings.                

In particular, protecting children's health from environmental risks is fundamental to EPA's mission. Caulks and paints containing PCBs were used in building some schools from 1950 to 1978. The proposed reinterpretation will help to promote healthy school environments by reducing exposure to PCBs in schools.

## III. Summary of Proposed Reinterpretation

Current EPA guidance states that building material contaminated by the migration of PCBs from PCB bulk product waste, such as caulk or paint, is considered a PCB remediation waste. The proposed reinterpretation would modify this guidance to specify that only PCB-contaminated building material from which the PCB bulk product has been removed from the substrate is a PCB remediation waste. That is, the distinction lies in whether or not the PCB bulk product is still attached to the building materials.

                    The reinterpretation being proposed in this notice would allow building material (                    *i.e.,*                     substrate) “coated or serviced” with PCB bulk product waste (e.g., caulk, paint, mastics, sealants) at the time of disposal to be managed as a PCB bulk product waste, even if the PCBs have migrated from the overlying bulk product waste into the substrate, provided there is no other source of PCB contamination on or in the substrate. However, if the substrate is not “coated or serviced” (                    *i.e.,*                     the PCB bulk product waste, such as caulk or paint has been removed from the building material) at the time of disposal and the substrate is contaminated with PCBs that have migrated from the bulk product waste (or from another unauthorized disposal), the substrate would be considered a PCB remediation waste. EPA is seeking comment on this proposed reinterpretation in its position.                

Finally, we would note that there may be instances where additional hazardous constituents are present and should be considered in making cleanup decisions. In addition, site-specific factors may influence how to manage these PCB wastes. Consideration of these constituents and site-specific factors, and coordination with appropriate regulators is important to ensure safe practices. Therefore, in such situations, we believe that the appropriate EPA regional office and regional PCB coordinator should be consulted as necessary for assistance with making these decisions. For instance, property owners have identified instances where PCB caulk contained high levels of other hazardous constituents, such as asbestos. Similarly, there are cases where PCB paint has been found to contain high levels of leachable metals. In such situations, care must be taken to determine the appropriate disposal option.

                    Please see the epa.gov/pcb Web page for further information and for instruction regarding how to submit comments. EPA will accept comments for 30 days from the date published in the                     **Federal Register**                    .
