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).
