               Fact  Sheet

                  The Environmental Protection Agency (EPA) is publishing regulatory controls
               that encourage the safe recycling and disposal of hazardous metal waste, and
               newly identified waste from mineral processing.

   The widespread practice of disposing of hazardous waste in units located
 directly on the land has been regulated by EPA's Land Disposal Restrictions
 (LDR) program for many years. A major part of the LDR program is to
 adequately protect public health and safety by establishing treatment standards
 for hazardous wastes before they can be disposed of in land disposal units.
 These treatment standards either specify that the waste be treated by a
 specified technology, or that they be treated by any technology as long as the
 concentration of hazardous constituents is below a certain level. Universal
 Treatment Standards specify the concentration levels for hazardous

   In addition to setting new treatment standards, another continuing task of
 the EPA is to better define which industrial materials are wastes, thus subject
 to regulation, and which should be excluded from regulation.

   LDR treatment standards are established for metal-bearing
 wastes-including TC waste (those with high levels of metal constituents)-and
 waste generated in mineral processing operations. These standards are based on
 the best technologies available to treat these or similar wastes. The UTS for 12
 metal constituents is revised to better reflect the entire universe of wastes that
 are subject to the treatment standards. Consequently, listed and characteristic
 hazardous wastes containing one or more metal constituents may have to comply
 with new treatment standards.

   Hazardous waste regulations are modified to define which secondary
materials from mineral processing are considered waste, and thus subject to
LDR treatment standards. Materials that are legitimately recycled and kept off
the land prior to recycling are conditionally excluded.  These provisions promote
the safe recycling of mineral processing secondary materials by reducing
regulatory obstacles to recycling, while ensuring the proper treatment and
disposal of hazardous wastes. Other miscellaneous issues related to mineral
processing wastes also are covered. In particular, the Toxicity Characteristic
Leaching Procedure is retained as a test for evaluating the toxicity
characteristic in these wastes.

   EPA is also amending the LDR treatment standards for soil contaminated
with hazardous waste. These standards are tailored to be more appropriate for
soils to make it more feasible to clean up contaminated sites without using
combustion technologies. Finally, EPA is excluding from regulation certain
wastewaters from wood preserving operations.
