Revision of Wastewater Treatment Exemptions for Hazardous Waste Mixtures
(‘‘Headworks Exemptions’’); Proposed Rule - April
8, 2003
The Environmental Protection Agency is
proposing in today's notice to add benzene and 2-ethoxyethanol to the list
of solvents whose mixtures with wastewater are exempted from the definition
of hazardous waste under the Resource Conservation and Recovery Act (RCRA).
The Agency studied two other solvents, 1,1,2-trichloroethane and 2-nitropropane,
and is not proposing at this time to add them to the current exemption.
Besides adding the two solvents to the exemption, the Agency is proposing
to provide flexibility in the way compliance with the rule is determined
by adding the option of directly measuring solvent chemical levels at
the headworks of the wastewater treatment system to the current requirements.
Finally, the Agency also is proposing to make additional listed hazardous
wastes (beyond discarded commercial chemical products) eligible for the
de minimis exemption, as well as adding non-manufacturing facilities to
those that qualify for this exemption if certain conditions are met.
The Agency is requesting comments on these and other potential exemptions
involving wastes managed in a wastewater system regulated under the Clean
Water Act (CWA).
The Agency is not proposing any changes or seeking comment on any other
provisions of the so-called "headworks rule," not specifically identified
in this notice as subject to possible amendment. Nor will the Agency respond
to any comments addressing any provisions of the headworks rule not specifically
identified in this notice as subject to possible amendment.
