    EPA is considering an interpretation of its regulations that would 
generally allow for recycling of plastic separated from shredder 
residue under the conditions described in the Voluntary Procedures for 
Recycling Plastics from Shredder Residue (Ref. 1), relying principally 
on the regulatory provision for excluded PCB products at 40 CFR part 
761. In the interest of transparency, EPA is inviting the public to 
provide comments as part of this process. 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 was approached by the Institute of Scrap Recycling Industries, 
Inc. (ISRI), regarding separation, recycling, use, and distribution of 
recycled plastics from shredder residue recovered from metals recycling 
facilities (referred to by ISRI as automobile shredder residue (ASR) 
aggregate). In a February 24, 2011 letter, ISRI requested ``written 
confirmation that separating plastics from ASR aggregate for use and 
distribution in commerce, using processes that reduce any PCBs that may 
be present to a level at or below which there is no unreasonable risk, 
is authorized'' under regulations promulgated pursuant to the Toxic 
Substances Control Act (TSCA) (see 16 U.S.C. 2605(e)) (Ref. 2). ISRI 
stated that:

    * * * analysis shows that the separation, recycling, 
distribution in commerce, and reuse of plastics from shredder 
aggregate is consistent with existing authorizations that allow the 
use and distribution in commerce of products that contain low levels 
of PCBs, including provisions for ``excluded PCB products'' and 
``excluded PCB manufacturing processes'' (as defined in 40 C.F.R. 
Sec.  761.3).

ISRI also stated that resolving regulatory uncertainty could lead to 
investments and further development in innovative methods to separate 
plastics from ASR aggregate that would produce broad environmental 
benefits and increase global competitiveness (Ref. 2).
    ISRI developed a set of voluntary procedures designed to prevent 
the introduction of PCBs that are regulated for disposal into recycled 
plastics recovered from shredder residue generated by metal recycling 
facilities. The Voluntary Procedures for Recycling Plastics from 
Shredder Residue (Ref. 1) includes development and implementation of a 
documented materials management system through: (1) Documented source 
control programs aimed at preventing the introduction of PCBs regulated 
for disposal into the shredder feedstock materials that contribute to 
any shredder residue from which plastics will be recovered for 
recycling; and (2) documented output control programs for facilities 
processing/producing/recycling plastics from shredder residue. The 
Voluntary Procedures for Recycling Plastics from Shredder Residue and 
supporting materials are available at EPA-HQ-OPPT-2012-0902.
    According to ISRI, 1 to 2 million tons of plastic are generated 
annually in ASR aggregate, most of which could be separated and 
recycled rather than disposed using novel technologies (Ref. 3). ISRI 
further delineates that the most common automotive plastic categories 
are polypropylene (PP), polyethylene (PE), polyurethane (PU), and 
polyvinyl chloride (PVC). ISRI also mentions acrylonitrile styrene 
butadiene (ABS) and high-impact polystyrene (HIPS) as additional types 
of automotive plastics found in ASR. By assuming that the 1 to 2 
million tons of plastic generated from ASR annually, when characterized 
by the percentage of total scrap plastics from a typical 2001 vehicle 
(Ref. 4), this would imply the following total annual volumes: PP 
(22.1%): 221,000-442,000 tons; PU (19.3%): 193,000-386,000 tons; nylon 
(12.4%): 124,000-248,000 tons; PVC (7.9%): 79,000-158,000 tons; ABS 
(7.4%): 74,000-148,000 tons; PE (4.4%): 44,000-88,000 tons; 
polycarbonate (3.9%): 39,000-78,000 tons; other engineering resins, 
including HIPS (10.9%): 109,000-218,000 tons; polyvinyl butyral (2.1%): 
21,000-41,000 tons; other (9.8%): 98,000-196,000 tons. However, ISRI 
notes that not all of these plastics are currently technically or 
economically feasible for recovery. But, ISRI highlights several 
plastics as likely candidates for recycling. These are PP, high-density 
PE, ABS, HIPS, and PU foam. Recovery of these plastics would require 
installation and operation of new or modified material separation 
equipment.
    To characterize the potential benefits of recovering and recycling 
plastics in ASR aggregate, ISRI commissioned a report from Nathan 
Associates, Inc. (Ref. 5). This report estimates economic benefits and 
environmental improvements from separating, sorting, processing, and 
recycling plastics found in ASR aggregate rather than disposing this 
material. In brief, the report finds that allowing plastics in ASR 
aggregate to be recycled would create demand for new capital equipment 
to be manufactured, installed, and operated in material separation 
facilities. This would lead to increased economic

[[Page 74008]]

activity both directly through purchase, installation, and operation of 
this equipment, as well as indirectly through increased demand for 
intermediate goods and services. The report also estimates positive 
environmental impacts on energy consumption, greenhouse gases, water 
use, and landfill space if virgin plastics were replaced with recycled 
material.
    EPA believes that recycling turns materials that would otherwise 
become waste into valuable resources. Recycling includes collecting 
recyclable materials that would otherwise be considered waste, sorting 
and processing recyclables into raw materials such as fibers, 
manufacturing raw materials into new products, and purchasing recycled 
products. Collecting and processing secondary materials, manufacturing 
recycled-content products, and then buying recycled products creates a 
circle or loop that ensures the overall success and value of recycling. 
Ultimately, recycling can generate a host of financial, environmental, 
and social returns. Some of these benefits accrue locally as well as 
globally. Examples of the general benefits of recycling include 
protecting and expanding U.S. manufacturing jobs and increasing U.S. 
competitiveness; reducing the need for landfilling and incineration; 
preventing pollution caused by the manufacturing of products from 
virgin materials; saving energy; decreasing emissions of greenhouse 
gases that contribute to global climate change; conserving natural 
resources such as timber, water, and minerals; and helping sustain the 
environment for future generations.
    With respect to recycling by the automotive industry overall, 
research on improvements in automotive design and construction has been 
conducted in order to facilitate the recycling of automotive materials/
components. The recycling of automotive steel has proven to be 
economically advantageous, so that wholesale automotive recycling is 
now widespread. Since a large volume of wastage is also generated, 
industry is interested in reusing as much automotive plastic as may be 
environmentally and economically feasible (Ref. 6).
    Increases in the recycling of plastics from ASR aggregate may also 
offer some benefits beyond that of other forms of plastics recycling. 
For instance, because substantial automotive recycling systems are 
already in place for the primary purpose of recovering steel, large 
quantities of ASR aggregate are already being simultaneously collected. 
Such available quantities of ASR aggregate may then be further 
separated and processed as necessary for purposes of reuse. Also, any 
potential expansion of ASR aggregate recycling capabilities could 
potentially generate excess capacity and/or technological advancements 
for use in the recycling of non-automotive products of a similar 
nature, such as large appliances for example.
    Such dynamics demonstrate the potential for creating a broad range 
of direct and indirect benefits that may be directly attributed to 
improved procedures and reduced regulatory barriers associated with the 
recycling of plastics in ASR aggregate. Any stimulation of the market 
for ASR aggregate may thereby help to not only protect and expand U.S. 
manufacturing jobs, but also foster new technologies and products while 
increasing U.S. competitiveness.
    While EPA agrees that recycling plastics from ASR aggregate could 
have net economic benefits and positive environmental impacts, EPA has 
not conducted an independent estimate of the precise magnitude or 
timing of these benefits and impacts. Therefore, EPA is not in a 
position to assess the underlying assumptions, or the savings per ton 
and multipliers, used in the benefit estimates from the Nathan 
Associates, Inc. report commissioned by ISRI. EPA notes that the report 
does not address the extent to which economic activity associated with 
the recycling of plastics from ASR aggregate would displace current 
economic activity associated with disposal of these plastics or the 
manufacturing of virgin materials. Nor does it address the timing of 
potential investments in new equipment. Additionally, the report relies 
on assumptions supported by limited data on plastic volumes, 
recoverability, environmental impacts, and market prices. EPA is 
interested in the public views on factors that may affect the 
direction, magnitude, and timing of benefits, costs, and environmental 
impacts associated with recycling plastics found in ASR aggregate 
rather than disposing of this material.
    As expressed in the Pollution Prevention Act of 1990, 42 U.S.C. 
13101 et seq., and the Agency's pollution prevention policies, EPA 
generally prefers recycling to disposal of materials within the waste 
management hierarchy. This general preference is a factor EPA has 
considered here. Plastics recovered from ASR aggregate could be 
incorporated into a wide variety of consumer products such as 
appliances, house wares, office goods, electronics, and carpeting. 
Plastics from ASR aggregate could also be returned in a closed loop to 
the automotive market. Although some of the same categories of plastics 
recovered from ASR aggregate are also used in certain food contact and 
medical applications, these recycled plastics are not expected to make 
large inroads into demand for virgin materials for these applications 
due to the voluntary procedures described in this notice. These 
procedures require plastic recyclers to include contractual provisions 
in sales contracts expressly stating that plastics containing recycled 
material separated from ASR aggregate may contain PCBs, and therefore 
the recycled plastics may be unsuitable for many products that 
currently use virgin plastic, such as products that involve oral 
contact.

III. Summary of Approach

    The interpretation under consideration would generally allow for 
the recycling of plastic separated from shredder residue under the 
conditions described in the Voluntary Procedures for Recycling Plastics 
from Shredder Residue (Ref. 1), relying principally on the regulatory 
provisions for excluded PCB products.
    TSCA section 6(e) generally prohibits the manufacture, processing, 
distribution in commerce and use of PCBs. However, EPA has by 
regulation excluded certain materials, including excluded PCB products, 
from these prohibitions. Excluded PCB products are defined as follows:

    Excluded PCB products means PCB materials which appear at 
concentrations less than 50 ppm, including but not limited to:
    (1) Non-Aroclor inadvertently generated PCBs as a byproduct or 
impurity resulting from a chemical manufacturing process.
    (2) Products contaminated with Aroclor or other PCB materials 
from historic PCB uses (investment casting waxes are one example).
    (3) Recycled fluids and/or equipment contaminated during use 
involving the products described in paragraphs (1) and (2) of this 
definition (heat transfer and hydraulic fluids and equipment and 
other electrical equipment components and fluids are examples).
    (4) Used oils, provided that in the cases of paragraphs (1) 
through (4) of this definition:
    (i) The products or source of the products containing = 50 ppm, the 
materials cannot qualify as excluded PCB products.
    EPA acknowledges uncertainty as to the source of the PCBs in 
shredder residue. However, EPA believes the procedures, as explained in 
the Voluntary Procedures document, can prevent the introduction of PCBs 
at levels = 50 ppm. EPA may periodically evaluate the 
processes and procedures involved in recycling plastics recovered from 
shredder residue. In addition, EPA believes it is likely that the 
number of potential sources of PCBs at levels = 50 ppm has 
declined since the TSCA section 6(e) prohibitions went into effect. If
