Ala. Admin. Code r. 335-14-6-.16 - Thermal Treatment
(1)
Applicability. The requirements of
335-14-6-.16 apply to owners or
operators of facilities that thermally treat hazardous waste in devices other
than enclosed devices using controlled flame combustion, except as
335-14-6-.01(1)
provides otherwise. Thermal treatment in enclosed devices using controlled
flame combustion is subject to the requirements of Rule
335-14-6-.15 if the unit is an
incinerator, and Rule
335-14-7-.08, if the unit is a
boiler or an industrial furnace as defined in
335-14-1-.02.

[Reserved].

[Reserved].
(4)
General operating
requirements. Before adding hazardous waste, the owner or operator
must bring his thermal treatment process to steady state (normal) conditions of
operation including steady state operating temperature using auxiliary fuel or
other means, unless the process is a non-continuous (batch) thermal treatment
process which requires a complete thermal cycle to treat a discrete quantity of
hazardous waste.
(5)
[Reserved].
(6)
Waste analysis.
In addition to the waste analyses required by
335-14-6-.02(4),
the owner or operator must sufficiently analyze any waste which he has not
previously treated in his thermal process to enable him to establish steady
state (normal) or other appropriate (for a non-continuous process) operating
conditions (including waste and auxiliary fuel feed) and to determine the type
of pollutants which might be emitted. At a minimum, the analysis must
determine:
(a) Heating value of the
waste;
(b) Halogen content and
sulfur content in the waste; and
(c) Concentrations in the waste of lead and
mercury, unless the owner or operator has written, documented data that show
that the element is not present.
(7)
[Reserved].
(8)
Monitoring and
inspections.
(a) The owner or
operator must conduct, as a minimum, the following monitoring and inspections
when thermally treating hazardous waste:
1.
Existing instruments which relate to temperature and emission control (if an
emission control device is present) must be monitored at least every 15
minutes. Appropriate corrections to maintain steady state or other appropriate
thermal treatment conditions must be made immediately either automatically or
by the operator. Instruments which relate to temperature and emission control
would normally include those measuring waste feed, auxiliary fuel feed,
treatment process temperature, and relevant process flow and level
controls.
2. The stack plume
(emissions), where present, must be observed visually at least hourly for
normal appearance (color and opacity). The operator must immediately make any
indicated operating corrections necessary to return any visible emissions to
their normal appearance.
3. The
complete thermal treatment process and associated equipment (pumps, valves,
conveyors, pipes, etc.) must be inspected at least daily for leaks, spills, and
fugitive emissions, and all emergency shutdown controls and system alarms must
be checked to assure proper operation.
(9)
[Reserved].
(10)
[Reserved].
(11)
[Reserved].
(12)
Closure. At
closure, the owner or operator must remove all hazardous waste and hazardous
waste residues (including, but not limited to, ash) from the thermal treatment
process or equipment.
(13)
Open burning, waste explosives. Open burning of
hazardous waste is prohibited except for the open burning and detonation of
waste explosives. Waste explosives include waste which has the potential to
detonate and bulk military propellants which cannot safely be disposed of
through other modes of treatment. Detonation is an explosion in which chemical
transformation passes through the material faster than the speed of sound (0.33
kilometers/second at sea level). Owners or operators choosing to open burn or
detonate waste explosives must do so in accordance with the following table and
in a manner that does not threaten human health or the environment.
|
Pound of waste explosives or propellants |
Minimum distance from open burning or detonation to the property of others |
|
0 to 100 .......... |
204 meters (670 feet) |
|
101 to 1,000 ........ |
380 meters (1,250 feet) |
|
1,001 to 10,000 ....... |
530 meters (1,730 feet) |
|
10,001 to 30,000 ...... |
690 meters (2,260 feet) |
(14)
Interim status permitted thermal treatment devices burning
particular hazardous wastes.
(a)
Owners or operators of thermal treatment devices subject to
335-14-6-.16 may burn EPA
hazardous wastes F020, F021, F022, F023, F026, or F027 if they receive a
certification from the Department that they can meet the performance standards
of Rule 335-14-5-.15 when they burn these
wastes.
(b) The following standards
and procedures will be used in determining whether to certify a thermal
treatment unit:
1. The owner or operator will
submit an application to the Department containing the applicable information
in 335-14-8-.02(10)
and 335-14-8-.06(2)
demonstrating that the thermal treatment unit can meet the performance
standards in Rule
335-14-5-.15 when they burn these
wastes.
2. The Department will
issue a tentative decision as to whether the thermal treatment unit can meet
the performance standards in Rule
335-14-5-.05. Notification of
this tentative decision will be provided by newspaper advertisement and radio
broadcast in the jurisdiction where the thermal treatment device is located.
The Department will accept comment on the tentative decision for 60 days. The
Department also may hold a public hearing upon request or at its
discretion.
3. After the close of
the public comment period, the Department will issue a decision whether or not
to certify the thermal treatment unit.
