Standards of Performance for New Stationary Sources and Emission
Guidelines for Existing Sources for Commercial and Industrial Solid
Waste Incineration Units
AGENCY: Environmental Protection Agency (EPA).
ACTION: Notice of data availability.
-----------------------------------------------------------------------
SUMMARY: This notice announces the availability of additional data
which supplement the database of emissions test reports used in
developing the final regulations for commercial and industrial solid
waste incineration (CISWI) units. We plan to issue the final
regulations by November 15, 2000. However, as we move toward
finalization of that rulemaking, we will continue to evaluate the
completeness of the rulemaking docket and may periodically add
additional material relevant to the development of the final
regulations (including, for example, additional data regarding the
characteristics of the incineration units considered in that rulemaking
and/or the emissions of pollutants from such units).
ADDRESSES: Docket No. A-94-63 contains the supporting information for
development of performance standards and emission guidelines for CISWI
units and is available for public inspection and copying between 8 a.m.
and 5:30 p.m., Monday through Friday, at the Air and Radiation Docket
and Information Center, U.S. Environmental Protection Agency, 401 M
Street, SW., Washington, DC 20460, telephone (202) 260-7548, fax (202)
260-4000. The docket is available at the above address in Room M-1500,
Waterside Mall (ground floor, central mall). A reasonable fee may be
charged for copying.

SUPPLEMENTARY INFORMATION: On November 30, 1999, we published proposed
regulations to limit air pollution emissions from CISWI units (64 FR
67092). In the 1999 proposal, we asked for comment on the proposed
emissions limitations for certain pollutants because of the limited
amount of data available for some pollutants in the source category.
Commenters stated that because the emissions test data upon which
several of the emissions limitations were based at proposal were
extremely limited, the proposed limitations were not representative of
actual CISWI unit performance. Several of the commenters suggested that
we consider expanding the CISWI emissions database by adding emissions
data from rulemakings which establish standards for sources that use
similar emissions control technologies under comparable operating
conditions. We have considered the comments and believe that it is
appropriate under the circumstances to consider certain emissions test
data from sources outside the CISWI category in order to help us better
evaluate the actual performance of CISWI units using similar control
technology. Specifically, because for three pollutants--dioxins/furans,
mercury, and hydrogen chloride--only one or two CISWI emissions tests
are available, we have decided not to rely only on those emissions
tests to determine the emissions limitations for those three
pollutants.
Instead, we intend to supplement the limited data for dioxins/
furans, mercury, and hydrogen chloride emissions from CISWI units
controlled by wet scrubbing systems with emissions data from similarly
controlled units outside of the CISWI category. That approach will
allow us to better characterize the actual dioxins/furans, mercury, and
hydrogen chloride emissions limitations achieved by units in the CISWI
category by providing additional information regarding the performance
of wet scrubbers under conditions similar to those experienced by CISWI
units.
Hazardous waste incinerator (HWI) units without waste heat boilers
that are controlled with wet scrubbing systems serve as a valuable
source of supplementary data for emissions of dioxins/furans (waste
heat boilers on HWI can result in increased dioxins/furans emissions
that are not representative of dioxins/furans emissions from CISWI
units). Those types of HWI units are generally similar to CISWI units
that are controlled by wet scrubbing systems. Thus, it is reasonable to
conclude that the emissions performance of HWI units without waste heat
boilers controlled with wet scrubbing systems is comparable to that of
CISWI units controlled with wet scrubbing systems. Accordingly, we
intend to combine the dioxins/furans emissions data from HWI units that
do not use waste heat recovery boilers and that are controlled with wet
scrubbing systems with the dioxins/furans emission data from CISWI
units controlled with wet scrubbing systems to estimate the dioxins/
furans emissions limitations achieved by units in the CISWI category.
Unfortunately, with respect to the other two pollutants (mercury
and hydrogen chloride) for which CISWI test data are extremely limited,
it is inappropriate to use emissions data from HWI units to supplement
the CISWI unit data. The mercury and hydrogen chloride emissions data
available from HWI units are based on the use of a different emission
control technology than wet scrubbing systems. That fact prevents us
from combining mercury and hydrogen chloride emissions data from HWI
units with that from CISWI units. Since appropriate HWI data were not
available, we considered other possible sources of data to augment
mercury and hydrogen chloride emissions data from CISWI units
controlled by wet scrubbing systems, and concluded that hospital/
medical/infectious waste incinerator (HMIWI) units controlled with wet
scrubbing systems could serve as a valuable source of supplementary
data for mercury and hydrogen chloride.
The HMIWI units are also generally similar to CISWI units that are
controlled by wet scrubbing systems. Thus, it is reasonable to conclude
that the mercury and hydrogen chloride emissions performance achieved
by HMIWI units controlled with wet scrubbing systems is comparable to
that of CISWI units controlled with wet scrubbing systems. Accordingly,
we intend to combine the mercury and hydrogen chloride emissions data
from HMIWI units controlled with wet scrubbing systems with the mercury
and hydrogen chloride emissions data from CISWI units controlled with
wet scrubbing systems to estimate the emissions limitations achieved by
units in the CISWI category for those pollutants.
That process for augmenting the CISWI data with appropriate HWI or
HMIWI data will result in dioxins/furans, mercury, and hydrogen
chloride emissions limitations which more accurately represent the
levels of such emissions limitations actually achieved by CISWI units
employing wet scrubbing systems. That approach to developing the
emissions limitations will provide a reasonable proxy for the actual
performance of the best-performing CISWI units and is the most
appropriate method, under the circumstances, for EPA to identify the
emissions limitations that are achieved by such units.
While we believe that emissions data for dioxins/furans, mercury,
and hydrogen chloride from the HWI and HMIWI categories are useful for
augmenting the CISWI data where insufficient CISWI emission data are
available, we do not believe that HWI, HMIWI, and CISWI units should
generally be characterized as similar units for the purpose of
determining emissions limitations for all pollutants for CISWI units.
The emissions data we intend to use from HWI and HMIWI units to
develop the final emissions limitations for CISWI units are presented
in Tables 1 and 2 of this document. Table 1 presents the dioxins/furans
emissions data from HWI units without waste heat recovery boilers and
controlled with wet scrubbing systems. The data were collected during
the development of regulations for HWI units. The units of measure are
nanograms toxic equivalent quantity per dry standard cubic meter (ng
TEQ/dscm) based on 1989 international toxic equivalency factors. Table
2 presents the mercury and hydrogen chloride emissions data from HMIWI
units with wet scrubbing systems. The data were collected during the
development of regulations for HMIWI units. The units of measure for
mercury are milligrams per dry standard cubic meter (mg/dscm), and the
units of measure for hydrogen chloride are parts per million (ppm).
