REGULATIONS FOR
BURNING HAZARDOUS WASTE
IN BOILERS AND INDUSTRIAL
FURNACES CLARIFIED
EPA is amending the regulations governing the burning of hazardous
waste in Boilers and Industrial Furnaces (BIF). These clarifications
provide guidance and correct unintended consequences of the rule.
Background
On February 21, 1991. the Environmental Protection Agency (EPA)
published a final rule that expands controls on hazardous waste
combustion by regulating air emissions from the burning of hazardous
waste in boilers and industrial furnaces (BIF). In particular, the rule
controls emissions of toxic organic compounds, toxic metals, hydrogen
chloride, chlorine gas, and particulate matter from those boilers and
industrial furnaces burning hazardous waste. In addition, the rule
subjects owners and operators of these devices to the general facility
standards applicable to hazardous waste treatment, storage, and
disposal facilities.
After publication of the final rule, EPA received many questions
requesting clarification on certain provisions of the rule. A technical
amendment to the final boiler and industrial furnace rule was
published on August 27, 1991. to clarify the operation of the regulation
and to correct certain unintended consequences.
As facilities began to comply with the BIF regulations, EPA received
additional questions about the way various provisions of the rule are
intended to work.

Action
EPA is issuing an additional technical amendment to
address these questions and clarify EPA's intent with the
BIF regulations. The clarifications incorporated into the
rule are:
• The definition of baseline hydrocarbon (HC) level for
industrial furnaces complying with the alternative HC
limit is clarified to require consideration of process
variability.
• Industrial furnaces complying with the alternative HC
limit may comply with the interim HC limit using a
conditioned gas HC monitoring system if they
demonstrate that a heated system is impracticable.
• Industrial furnaces that cannot comply with the 20 ppmv
HC limit by August 21. 1992, may apply for a case-by-
case time extension to make physical changes to the
facility in order to comply with that HC limit.
• The metals and total chlorine feed rate operating limits
for Tier I and adjusted Tier I are based on screening
limits, not the compliance test.
• Adjusted Tier I feed rate screening limits may be used in
dispersion situations where the Tier I and Tier II
screening limits are precluded.
• Several requirements are clarified to account for facilities
that comply with adjusted Tier I limits.
• BIF storage units are subject to the air emissions
standards of Subparts AA and BB of Parts 264 and 265.
• The definition of plasma arc and infrared incinerators are
clarified to include only those devices that use an
afterburner.
• Facilities that comply with the Tier I and Tier I metals
and chlorine and chlorine controls and that have
uncontrolled emissions that meet the particulate matter
standard need not establish a limit on production rate
during interim status.
