Revised Technical Standards for Hazardous Waste Combustion 
Facilities; Correction

ACTION: Notice of data availability; correction.

-----------------------------------------------------------------------

SUMMARY: The Environmental Protection Agency published a notice of data 
availability and invitation for comment in the Federal Register of May 
2, 1997, on the following information pertaining to the proposed 
revised standards for hazardous waste combustors (61 FR 17358 (April 
19, 1996)): Report on the status of setting national emission standards 
for hazardous air pollutants (NESHAPS) based on the revised emissions 
database; report on the selection of pollutants and source categories, 
including area and major sources; report on the status of various 
implementation issues, including compliance dates, compliance 
requirements, performance testing, and notification and reporting 
requirements; and report on the status of permit requirements, 
including waste minimization incentives. The notice inadvertently 
omitted four paragraphs and contained six incorrect numbers.

(5302W), U.S. Environmental Protection Agency, 401 M Street, SW.,

Correction

    In the Federal Register issue of May 2, 1997, in FR Vol. 62, No. 
85, insert the following four paragraphs of text between the last 
paragraph on page 24240 and the first paragraph on page 24241:
    Option 1: Eliminate DRE Testing Except for Potentially Problematic 
Sources. Under this option, DRE testing would be waived for all 
sources, except those that are considered to be potentially 
problematic--sources that inject hazardous waste into the combustor at 
locations other than the flame zone. Thus, for example, the source 
discussed above that injected waste into an unfired afterburner (and 
failed to achieve 99.99% DRE at low CO and HC levels) would be required 
to perform DRE testing under this option.
    Option 2: Single DRE Test for All Sources or Only for Potentially 
Problematic Sources. Under this option, either all or only potentially 
problematic sources (as defined above) would be required to perform a 
single DRE test, unless the facility undergoes a major modification of 
pollution control equipment, process change, or waste feed composition 
that could significantly affect combustion performance. We request 
comment on how to determine when such a change is about to occur and 
thus trigger the need for a DRE test. One approach is to rely on the 
requirements for applying for a revised Title V or RCRA permit 
modification (Class 2 or 3) to identify changes warranted a DRE re-
test.
    Option 3: Periodic DRE Testing for All Sources or Only for 
Potentially Problematic Sources. Under this option, all or specific 
sources must perform a periodic demonstration of DRE. Potential 
frequencies under consideration are a five, ten or twenty year 
frequency. The purpose of these tests would be to confirm that the unit 
is still achieving a high level of combustion performance over the life 
of the unit. As for option 2, a DRE test would have to be performed at 
any time that a major change to the facility occurred that could 
significantly affect combustion performance.
    The Agency specifically invites comment on these options for 
waiving DRE testing. In addition, note that these options are not 
mutually exclusive.
