This document is an mfdcndum lo the background document for the First Third wastes 10
support the 40 CFR Pan 268 Land Disposal Restrictions. This document updates the capacity
analysis for K061 wastes based on the new treatment standards established for high zinc K061 and
c:i more recent information received by EPA on high zinc K061 generation, management, and
treatment. The purpose.of this document is to provide information' to support EPA's
determination that adequate treatment capacity exists for high zinc K061 wastes. EPA notes'that
the analysis is in some ways academic, given that the time for granting national capacity variances
for K061 ended in August 1991. (See RCRA section 3(XM(h)(2).] Nevertheless, the information
on capacity should be useful to the regulated community.
This rule establishes new treatment standards under the land disposal restrictions for high
zinc K061 wastes. EPA has determined that sufficient treatment capacity exists to treat these
wastes. Although EPA has established numeric ircaimcr; standards for high zinc K061 based on
the performance of high temperature metals recwcry (HTMR), the Agency does not preclude
the use of other treatment technologies that can meet the numeric standards established for this
waste. In conducting this capacity analysis for high zinc K061 wastes, the Agency has confirmed
the earlier estimates for generation volumes of high zinc K061 and again determined that there is
sufficient available treatment capacity for these wastes.
Background
K061 is emission control dust/sludge from the primary production of steel in electric arc
furnaces. Treatment standards for nonwawwatcr forms of KQ61 were promulgated as part of the
First Third final rule on August 8,1988. Two subcaicgories of nonwasiewater forms of K061
were defined: the low zinc subcatcgory (less than 15 percent zinc) and the high zinc subcategory
(greater than 15 percent). The treatment standard lor the low zinc subcategory was based on
stabilization.1 For the high zinc si bcategory, the final standard was "No Land Disposal Based on
High Temperature Metals Recovery as a Method of Treatment" {53 FR 31221). Due to a
shortage in HTMR capacity, the effective date was delayed until August, 1990. An interim
numerical standard based en the performance of stabilization technology was in effect until that
time. The Third Third proposed :iile requested comments on the possible extension of the
interim standard for high zinc K061 for one additional year (54 FR 4S457). Responses from
industry indicated that HTMR processes were being built but would not be available by August,
1990. Therefore, EPA extended the interim treatment standard for an additional year until
August. 1991. At that point, the standard of "No Land Disposal Based on HTMR". would go into
effect.
In the Third Thud proposed rule, EPA also proposed to amend the existing treatment
standard for high zinc K0<51 waste* to he resmdu'nj-in 3 HTMR furnace. Hwrupr, since 'he-
existing standard was under review by the District of Columbia Court of Appeals, EPA decided
not to amend the standard in the Third Third rule. The Natural Resources Defense Council,
'Low zinc K061 wastes arc net addressed in this rule and arc therefore not included in this
background document.
-------
005422
Chemical Waste Management. Inc., and the Hazardous Waste Treatment Council claimed EPA
unlawfully exempted the slag residues thai result from the "treatment" of K061 in zinc smelters
f-om ihc Land Disposal Restrictions. EPA had determined in the First Third rule that it lacked
Vie authority to establish any treatment slan-Jardi for ihc slag residues that rauli from ihi!y. However, the Court held thst tl'A had incorrectly -interpreted its statutory authority
nnd remanded the issue for further consideration.
This rulemaking is in response to the Court's remand. EPA has determined that K061
slag is subject to RCRA regulations. In addition, the Agency has established new treatment
standards for high zinc K061 wastes based on the performance of HTMR.
Response to Comments
In the proposed rule, EPA recognized that generation and management of K06! wastes
and the amount of available treatment may have changed since the capacity analysis for K061 was
conducted for the First Third rule. Therefore, the Agency requested additional information on
tie generation and management of high zinc K06I wastes and the capacity of processes that can
treat these wastes. Six commented focused on HTMR capacity issues: Armco Advanced
Materials Company, the Steel Manufacturers Association, the Specialty Steel Industry of the
United States. Waste Management Inc., the American Iron and Steel Institute, and International
Mill Service Inc.. Four commenters noted that there are other treatment processes besides
HTMR that can meet the numeric treatment standards: Encycle. Michigan Disposal, Conversion
Systems Inc., and Zinox. The information received was used to update the analyses presented
below. /
Waste Generation
For the First Third rule, data from EPA's National Survey of Hazardous Waste
Treatment, Storage, Disposal, and Recycling Facilities (TSDR Survey) was used to estimate that
83.1 million gallons (345,000 tons) per year of K061 (both-high and low zinc) would require
alternative treatment capacity (53 FR 31193). Data initially received from commenters on the
first Third proposed rule indicated that approximately 75 percent of K061 waste contained 15
percent or more total zinc. Therefore, according to TSDR data 62 million gallons (260,000 tons)
.per year of high zinc K061 would require treatment capacity. However, this figure may be ah
underestimate of high zinc K061 generation.
Two other sources have provided the Agency with data on the generation of high zinc
K061. The Horsehead Resource Development Company (HRD), the primary commercial facility
currently recovering zinc from K061 wastes using HTMR, estimates that approximately 415,000
tons of high zinc K061 will be generated in 1991.
The American Iron and Steel Institute (AISI), which represents most of the generators of
KG61, estimates that approximately 20' pounds of K061 are generated per ton of steci that is
produced {i.e., a waste-to-product ratio of 1 percent.) According to AISI, steel production in
1989 was approximately 98 million tons. Approximately 35 million tons (36 percent) of all steel is
produced is electric arc furnaces. Therefore, using the estimated waste-to-product ratio of 1

percent, approximately 350.000 tuns of KOfil w.-ir. pcncratcu in 1989. High zinc K061 is generated
during carbon steel production. Since carbon MIT) accounts for SI percent of the steel produced
in electric arc furnaces, the volume? of high zinc K'Cil produced in 1W!9 was approximately
8--B
9 pi
Since there is .3 {ftsfwpnncy in'irK' c%iii*;;ii(". .-if hii;h /inc Kflfil veneration, for the
purposes of this capacity analysis, the highest ligurc. 4I5.(KK) tons, was used to estimate ihc
volume of high zinc K06J requiring treatment.
Current Management Practices , .
AISI estimates that most high zi'nc K06! th;it is treated (about 9u percent) currently goes
through HTMR.. Tne volume of high zinc K061 being stabilized anci zabsequentty land disposed is
therefore low. The Agency believes that this mjy bt due to the existing incentives to recycle high
zinc K061. Stabilization and landfilling costs are tisph, and sonic states have provided lax
incentives not to land dispose hazardous wastci. Thus, the generators of high zinc K061 that are
treating their waste are doing so primarily by rveyclinj; their wastes through HTMR.
HTMR Caaacitv
The currently available HTMR capacity is estimated to be 533,000 tons per year. In
addition. 40,000 tons of HTMR capacity is expected to become available by August. 1991. The
following facilities account for the available capacity:
• Three Horsehead Resource Development plants are currently operating with a
lota! annual capacity of 455,000 tons. HRD confirmed that capacity at their
Palmerton. Pennsylvania plant is 265.000 tons per year, capacity at their Calumet.
Illinois plant is 90,000 tons per year, and indicated that their new Rockwood
Tennessee plant is now operational with a capacity of 100.000 tons rather than the
. expected capacity of 80,000 ;cr,r, reported in the proposed rule.
• Internationa! Mill Services is currently operating two thermal dust trsaimcnt plants
with a combined yearly capacity of 18.000 tons.
» Zia Technology has a zinc recovery facility Capable of processing 60.000 tons per
year of high zinc K061. Zia has ihe potential io process up to 90,000 tons of KOfil
per year (they are currently permiuc.-! for 60.000 tons). Their process can handle
both low and high zinc, but there is a penalty for low zinc.
• Laclede Steel Company has contracted with Elkem to construct a HTMR furnace
wilh an annual capacity of 40.000 tons per year. This furnace should be operable
in August, 1991.

005-4JM
Thecurrcm'y available stnbiiizaiicn cap;id!y reported irs iha Third Third llfjiii rust is
approximately 1.3 million tons per year (55 FR 22635). However, greater capacity for treating
K061 may now be present. For example, Michigan Disposal. Inc. claims that chemical fixation
and stabilization techniques can meet thp K0<5! treatment standards. Mkhi»b« Disposal's current
SiarrlSizaJirm capacity for high zinc KOftl is apnrnvimately-100,000 tons per year. Ariciiiionallv.
Cheni Waste Mjsnagemenl and Peoria Conversion Systems may also have stabili/.iition capacity, •
Kxtractiyc Metallurgy Capacity
In addition to HTMR and stabilization, other effective techniques may be present to treat
high zinc K061 waste. For example, Encycle indicates their metal recovery process can treat K051
wasie. Their .current treatment capacity is approximately 30,000 tons per year, and this capacity is
expected to increase to 60,000 tons within a year. Encycle typically recovers zinc and either
stabilizes the iron residue or sends it off site as feed. Trier, nay be additional facilities that can
treat high zinc K061 with extractive metallurgy processes.
Capacity implications
Based on the data presented above, sufficient HTMR capacity exists to handle the 1991
demand £r>r zinc recovery from K061 wastes. There is also available stabilization and extractive
metallurgy capacity thai can meet the treatment standards. Therefore, the Arency has
determined that there is sufficient capacity to handle the volumes of high zinc K061 requiring
treatment under the Land Disposal Restriction. •

General Facility Information
Horsehead Resource Development (HRD) and Zinc Corporation of America (ZCA)
operate pyrolitic metal recovery facilities in Palmcrtori, Pennsylvania, and Calumet, Illinois. These
processes are used primarily to recover zinc from K061 waste. A ?.inc recovery facility in
Rock-wood, Tennessee, is cvpcctcd to cor.ic on line in 1991.
Metals Recovered
HRD recovers zinc from K061. Mr. Jancck indicated that their process can efficiently
recover zinc from KG61 having a zinc conccmraiion higher man 10 percent.
Process Information
HRD's zinc recovery process docs not cxtrnci nickel and chromium. Therefore, HRD
blends high/nickel/high chromium K061 (generated from stainless and specialty steel
manufacturing) with low nickel/low chromium K061 (from carbon steel manufacturing) so that the
resultant slag passes the TCLP for nickel and chromium. Mr. Janeck indicated that INMETCO
processes most of the high nickel/high chromium K0614>ccausc they extract the nickel and
chromium. INMETCO's process concentrates zinc in the baghouse dust which is then sent to
HRD for zinc recovery.
Mr. Janeck also indicated that the stag from the HRD process meets the stabilization
standard set for low zinc K061.
Since fluxes and rcductahls are added to the process, there is no significant K061 volume
reduction as a result of zinc recovery. ,
K061 Generation and Recovery Capacity
HRD marketing studies suggest mat the generation of KCoi wiii increase by approximately
six percent from 1990 to 2000. KQ61 generation is projected to be approximately 500,000 tons in
1991 (this quantity does not include the low zinc, high nickel/high chromium K061, which is
estimated to be 10 to 20 percent of the high zinc, low nickel/tow chromium quantity).

Mr. Herbst indicated that Chem Waste Management (CWM) stabilizes predominantly tow
zinc K061. He does not have information of how much high zinc K061 CWM processes, hut be
acknowledged that CWM processes very little high zinc K061. CWM has stabilization capacity at
their Indiana and Alabama facilities to process K061.
In the KQ61 background document, CWM submitted a letter to EPA indicating their
interest in building a high temperature metals recovery (HTMR) facility in the Jackson,
Mississippi area that could manage up to 100.000 tons of K061 per year. Mr. Herbst indicated
that the HTMR project has been put on held, but declined to provide the reason for putting the

Mr. Cigan staled that data used for the BOAT was only one trial using high zinc K061.
Waelz kilns are large units used to hand!e'K061 from generators in the region. The variability in
K061 allows HRD to blend the feed to meet the TCLP standards. However, HRD may have
problems achieving the vanadium and thallium (and other trace metals) standards because the
BOAT standard was set using an atypical process input. Mr. Cigan indicated that low zinc K061
is mixed with high zinc K061 to achieve the optimal feed, which has to be 20 percent zinc by
weight Me also reported that the Rockwood plant will be operational by August 1991.
Flame Reactor
This process targets a different K()61 market than the Waelz kiln. Flame reactors are
designed to be constructed on-site at arc furnaces to process the K061 dust The flame reactor is
restricted to handle one to three sources of dust. Because the process is different (i.e., slag is
different) than the Waelz kiln and the design arrangement does not allow blending of K061; the '
Ocir.c reactor may not achieve the TCLP standards.
K06I Generation
Mr. Cigan revised Thoma* Jdncck'i csUmaic of the generation of high zinc K061 wastes
from 550,000 tons per year to 415,000 Ions per year.

lost half of their K061 business. Wayne believes that EPA should go with the delisting numbers.
The wastes they currently stabilize include F006. TTwir stabilization capacity is 5 million gallons a
month (200,000 yd-). Forty percent of their total capacity could be dedicated to K061. They are

Mr. Odie indicated thai available capacity for K061 depends on what they choose to
process. The firm has the capacity to process solids of up to 5,000 tons per month. They
currently recover zinc. The process they use produces pyrrhic hydroxide as an end product which
can be used as a reducUsril and can be used as a feed. In general, the Firm uses higher zinc
content materials. At present, most of their capacity is taken up by other wastes. They are
planning to take iron liydrOxkJv wasie and make it into some other compound since for these
wastes the BOAT was not clear. There is no residue generated from the hydrometallorgical
process. The other option is to recover zinc and stabilize the iron residue. The firm would like

K061 Capacity Ann lysis for the

005441
RCRA hazardous waste K06! is descried as emission control
dust/sludge from the primary production of steel in electric furnaces.
K061 is listed as a hazardous waste ui.'i.du&e of tfcs presence of hexavsler.t
chromium, lead, and cadmium. For K061 containing £1S percent zinc (high
zinc K061), the Agency has identified the BOAT technology to be high
temperature metals recovery. For K061 containing 5 percent of the K061 requiring alternative
treatment is high zinc K061. Table 2-23 shows the volumes of K061 waste
identified by the Agency as requiring alternative treatment. •
One waste stream reported in the TSDR Survey (67,920 gallons) was
reported as a mixed K061 and K062 stream. After reviewing the survey
information, it was determined that the waste stream had been'received
from an offsite fac'ility and was directly landfilled. Because of this
information and the characteristics of the waste codes involved, the
Agency assumed that the waste stream is an inorganic solid. The Agency
believes that these wastes will likely be segregated upon promulgation of
the land disposal restrictions and, therefore, will no longer be
generated as a mixed waste stream. To conservatively estimate the
volumes of K061 and K062 that will require alternative treatment, the

entire volume of this waste stream was assigned to the BOAT technologies
for both K061 and K06Z, with no resulting impact on capacity variance
determinations for those wastes (see below).
The Agency believes that sufficient high-temperature metals recovery
capacity does not exist for high zinc K061. For the proposed rule
(R~f.4 Aef. 11), EPA analyzed the length of the required to install a
BDA". treatment system for K061 waste. Based on this analysis, EPA
estimates that a BOAT treatment system could be constructed within two
years. This estimate does not include the time required for preparation
and approval of RCRA and/or State permit applications because high
temperature metal -recovery is considered recycling, zrtd as such, is
exempt from RCRA permitting.
Therefore, the Agency is granting a 2-year national capacity variance
from the ban effective date for KOol wzstes requiring high temperature
metals recovery, however, the Agency 4s sett .j an interim standard for
high zinc KOol based on stabilization.
Several commenters were concerned that commercial facilities with
available stabilization capacity were not permitted specifically for K061
waste. However, review of the TSDR Survey data indicates that there is
approximately 205 million gallons of existing (not planned) available
capacity at facilities that accepted K061 for stabilization in 1986 or
said they would accept K061 for stabilization. These facilities included
