Dyes and Pigments: July 23, 1999Hazardous Waste Management System; Identification and Listing of Hazardous Waste: Dye and Pigment Industries; Land Disposal Restrictions for Newly Identified Wastes; CERCLA Hazardous Substance Designation and Reportable Quantities; Proposed Rule July 23, 1999:
The EPA proposed to list two of three wastes from the dyes and pigment industries as hazardous wastes under the Resource, Conservation, and Recovery Act (RCRA), which direct EPA to determine whether certain wastes from the dye and pigment industries present a hazard to human health or the environment. The effect of listing these wastes will be to subject them to stringent management and treatment standards and to emergency notification requirements if there are releases of these hazardous wastes to the environment. EPA is proposing concentration-based listings for the two wastes, such that waste generators have the option of determining that their specific waste is nonhazardous. To have their waste classified as nonhazardous, generators must determine the levels of constituents in their wastes, and certify to EPA that their wastes are below the regulatory levels of concern.

Listing Determination for Two Dye and Pigment Wastes (PDF) (2 pp, 14K)
EPA proposed to list two dye and pigment wastes as hazardous wastes, and not to list one other waste. This is the first time that EPA is proposing concentration-based listings, which stipulate constituent-specific concentration levels in wastes at which the wastes will be hazardous. The proposed concentration-based listings would be self-implementing. Because the dye and pigment industries are known to use batch processes, the dye and pigment wastes are potentially highly variable wastes. For such wastes, a concentration-based approach is more cost-effective and prevents the unnecessary regulation of nonhazardous wastes.

- Background Document for Capacity Analysis for Land Disposal Restrictions - Newly Identified Dye and Pigment Manufacturing Wastes (Proposed Rule) (PDF) (34 pp, 137K) This report documents the capacity analysis that EPA conducted to support
the proposed land disposal restrictions for newly proposed dye, pigment,
and food, drug, and cosmetic (FD&C) colorant wastes. EPA conducts
capacity analyses for all newly identified hazardous wastes to evaluate
the need for national capacity variances from the land disposal prohibitions.
- Best Demonstrated Available Technology (BDAT) Background Document for
Dye and Pigment Production Wastes - Deferred Wastes K167 and K168 (PDF) (86 pp, 304K) This
report provides background information to support the development of land
disposal standards for proposed listings of wastes K167 and K168 from
the the production of dyes and pigments. This report does not contain
information claimed as confidential business information (CBI).
- Background Document for Identification and Listing of the Deferred Dye and Pigment Wastes (PDF) (36 pp, 190K) - This report provides background information to support the proposed listings for the dye and pigment industries. The document contains information on the specific wastes, including data on waste quantities generated and disposal practices. The document also describes how EPA chose the constituents of concern for establishing concentration levels in the listing.
- Development of Risk-Based Listing Concentrations for Hazardous Constituents
Contained in Spent Filter Aids and Triarylmethane (TAM) Wastewater Treatment
Sludges Background Document (PDF) (101 pp, 503K) - This document presents EPA's assessment
of potential risk from spent filter aids and triarylmethane (TAM) wastewater
treatment sludges. EPA's risk assessment of spent filter aids and TAM
sludges is designed to produce risk-based concentration limits for potentially
hazardous constituents contained in these two waste streams. The risk-based
concentrations resulting from the risk assessment described herein are
constituent-specific numerical limits for hazardous constituents in TAM
sludge and spent filter aids that are considered to be protective of human
health. They can be defined as the maximum constituent concentrations
at which adverse health effects from any single constituent do not exceed
levels of concern.
