----------
*(I,T) should be used to specify mixtures containing
ignitable and toxic constituents.
(b) Listing
Specific Definitions:
(1) For the purposes of the F037 and F038 listings,
oil/water/solids is defined as oil and/or water and/or
solids.
(2)(i) For the purposes of the F037 and F038 listings,
aggressive biological treatment units are defined as
units which employ one of the following four treatment
methods: activated sludge; trickling filter; rotating
biological contactor for the continuous accelerated
biological oxidation of wastewaters; or high-rate
aeration. High-rate aeration is a system of surface
impoundments or tanks, in which intense mechanical
aeration is used to completely mix the wastes, enhance
biological activity, and
(A) the units employs a minimum of 6 hp per million
gallons of treatment volume; and either
(B) the hydraulic retention time of the unit is no longer
than 5 days; or
(C) the hydraulic retention time is no longer than 30
days and the unit does not generate a sludge that is a
hazardous waste by the Toxicity Characteristic.
(ii) Generators and treatment, storage and disposal
facilities have the burden or proving that their sludges
are exempt from listing as F037 and F038 wastes under
this definition. Generators and treatment, storage and
disposal facilities must maintain, in their operating or
other onsite records, documents and data sufficient to
prove that:
(A) the unit is an aggressive biological treatment unit
as defined in this subsection; and
(B) the sludges sought to be exempted from the
definitions of F037 and/or F038 were actually generated
in the aggressive biological treatment unit.
(3)(i) For the purposes of the F037 listing, sludges are
considered to be generated at the moment of deposition in
the unit, where deposition is defined as at least a
temporary cessation of lateral particle movement. (ii)
For the purposes of the F038 listing,
(A) sludges are considered to be generated at the moment
of deposition in the unit, where deposition is defined as
at least a temporary cessation of lateral particle
movement and
(B) floats are considered to be generated at the moment
they are formed in the top of the unit.
