Effluent Limitations Guidelines, Pretreatment Standards, and New 
Source Performance Standards for the Iron and Steel Manufacturing Point 
Source Category

AGENCY: Environmental Protection Agency (EPA).

ACTION: Extension of comment period; correction.

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

SUMMARY: On December 27, 2000 (65 FR 81964), EPA published proposed 
effluent limitations guidelines, pretreatment standards, and new source 
performance standards under the Clean Water Act (CWA) for wastewater 
discharges from iron and steel manufacturing facilities. The proposed 
regulation would revise technology-based effluent limitations 
guidelines and standards for wastewater discharges associated with the 
operation of new and existing iron and steel facilities.
    This action presents clarifying discussion on seven regulatory 
issues related to the proposed effluent limitations guidelines and 
standards for the iron and steel industry and solicits public comment. 
This action also contains corrections to certain portions of the 
proposed regulation and accompanying preamble to eliminate 
inconsistencies in the proposal, and to correct potentially confusing 
typographical errors.
    This action also provides additional information on the 
pretreatment hearing and public meeting.
    This action also announces that EPA is extending the comment period 
on the proposed rule until March 26, 2001. EPA is providing this 
extension in response to numerous requests for additional time to allow 
the public to consolidate their comments on the proposal.

DATES: EPA must receive comments on this action by midnight March 26, 
2001. This is also the new deadline for submitting comments on the 
proposed rule, which was published on December 27, 2000 (65 FR 81964). 
On February 20, 2001, EPA will conduct a hearing on the pretreatment 
standards (9:00 AM-10:30 AM), followed by a public meeting on the 
entire proposed rule, including issues in today's action (10:30 AM-
12:00 PM and 1:00 PM-2:30 PM).

I. Purpose of This Action

    In this action, EPA presents seven regulatory issues related to the 
proposed effluent limitations guidelines and standards for the Iron and 
Steel Manufacturing Point Source Category. This action also contains 
corrections to certain portions of the proposed regulation and 
accompanying preamble. This action also announces March 26, 2001 as the 
new deadline for submitting comments on the proposed rule. EPA solicits 
public comment on all information presented in this action and in the 
administrative record supporting this action.

II. Solicitation of Public Comment on New Regulatory Issues

    EPA has identified seven substantive issues related to the proposed 
rulemaking to bring to the public's attention. These issues are 
discussed below. EPA solicits comment on these issues and the various 
approaches the Agency is considering to resolve these issues.
A. BPT Revision for Semi-wet BOF Operations
    In the effluent limitations guidelines and standards promulgated 
for the Iron and Steel Manufacturing Point Source Category in 1982, BPT 
and BAT for basic oxygen furnaces with semi-wet air pollution controls 
(semi-wet BOFs) were set at no discharge of process wastewater 
pollutants to waters of the United States. In the December 27, 2000 
notice, we proposed to revise BAT for semi-wet BOFs in the steelmaking 
subcategory. We had intended to revise BPT at the same time so that BAT 
and BPT would be consistent. However, we failed to do that. Instead, we 
republished the 1982 BPT of no discharge of process wastewater 
pollutants for semi-wet BOFs, with the result that the BPT would be 
more stringent than the proposed BAT. EPA did not intend this anomalous 
result. Today's action advises the public that we intend to revise BPT 
to be consistent with BAT in the final action.
    Conforming BPT to BAT, as EPA intended, would allow for the 
discharge

[[Page 10254]]

of process wastewater from semi-wet BOFs, which EPA considers 
desirable, because certain safety concerns preclude some sites 
currently from balancing the water applied for BOF gas conditioning 
with evaporative losses to achieve zero discharge. Specifically, some 
sites operate their semi-wet systems with excess water, which they use 
to flush the air pollution control ductwork in order to prevent the 
buildup of debris within the ductwork. If wet debris accumulates within 
the ductwork, it has the potential to fall back into the BOF, and may 
cause explosions and process upsets. The sites thus discharge the 
process wastewater used for flushing. EPA does not want to discourage 
this flushing practice because of its safety implications. 
Consequently, EPA intends to revise BPT for semi-wet BOF operations to 
conform to the proposed BAT so as to allow for the discharge of process 
wastewater under BPT for the reasons set forth above. The pollutants 
regulated under a revised BPT for semi-wet BOF operations would be TSS 
and pH. EPA is not proposing to regulate oil and grease in wastewater 
discharges from semi-wet BOF operations because there is virtually no 
oil and grease is in the wastestream. (EPA notes that oil and grease 
was not regulated in the 1982 regulation for this segment.)
    If EPA were to revise BPT limitations for semi-wet BOF operations, 
EPA would base the new limitations for TSS on pollutant concentrations 
established in the 1982 rulemaking for both wet-open combustion and 
wet-suppressed combustion BOFs (150 mg/L maximum daily and 50 mg/L 
maximum monthly average concentrations for TSS) and the production-
normalized flow (PNF) (10 gpt) developed in the proposed rule for semi-
wet BOFs. It is reasonable to transfer limitations from these segments 
to the semi-wet BOF segment because of similarity in wastewater 
characteristics and in the proposed treatment technology. Using these 
data, EPA has calculated the BPT limitations shown in Table II.A.1 for 
semi-wet BOFs, which EPA would promulgate under this approach:

       Table II.A.1.--Effluent Limitations (BPT) for Semi-Wet BOFs

                                                               Maximum

    The pH level would be maintained between 6.0 and 9.0 su at all 
times.
    EPA solicits comment on this issue, including the limitations 
specified above.
B. PSES Limits for Electroplaters
    The proposed regulation at section 420.66(g) (65 FR 82076) would 
establish concentration-based PSES for electroplating operations in the 
Steel Finishing Subcategory. These concentration-based limits were 
carried forward from the current regulations for the Metal Finishing 
Category. See 40 CFR 433.15 (2000 ed.). All other limitations and 
standards set forth in the proposed iron and steel rule are mass-based. 
EPA is considering converting the proposed concentration-based limits 
for electroplating (see Table II.B.1) to mass-based limits using the 
PNFs proposed for electroplating operations (see Table II.B.2). Table 
II.B.3 then presents the mass-based PSES limits for electroplating 
operations, for which it solicits comments today.

    EPA does not believe this action will result in increased costs to 
the industry. EPA solicits comment on whether to establish mass-based 
PSES limits for electroplating operations in the Steel Finishing 
Subcategory. EPA also solicits comment on the specific mass-based 
pretreatment standards set forth in Table II.B.3 and the approach 
employed to develop those pretreatment standards.
C. Limitations and Standards for Ammonia-N in Steel Finishing 
Subcategory
    The proposed regulation would regulate ammonia (as N) at BAT 
(section 420.64(a)), NSPS (section 420.65(b)(3)), and PSNS (section 
420.67(b)(1)) levels in the stainless steel segment of the Steel 
Finishing Subcategory. EPA intended for the limits to apply only to 
nitric acid picklers using urea to control NOX emissions, 
because ammonia (as N) is present in wastewater from stainless steel 
finishing operations at significant levels only when nitric acid is 
used in pickling baths and urea is used to control NOX 
emissions. However, EPA did not make this distinction in the proposal. 
EPA intends to correct this error with today's notice. Consistent with 
EPA's original intent, EPA would specify in the final action that the 
BAT, NSPS, and PSNS limits as presented would apply only to stainless 
steel finishing operations with nitric acid pickling baths in which 
urea is used to control NOX emissions, and solicits comment.
    The Agency also solicits comment on not establishing nationwide 
limits for ammonia (as N) for any operations in the stainless steel 
segment of the Steel Finishing subcategory. EPA notes that there are no 
limits for ammonia (as N) under the current Part 420 regulations for 
this segment. We would allow permit writers and pretreatment control 
authorities to use best professional judgment (BPJ) to make case-by-
case determinations of the need to regulate ammonia (as N) in 
wastewater discharges from nitric acid pickling operations. EPA is also 
considering providing guidance for best management practices to reduce 
discharges of ammonia (as N).
D. Chromium (VI) Data
    The proposed regulation would establish BAT (section 420.64(b)), 
NSPS (section 420.65(b)(4)), and PSNS (section 420.67(b)(2)) to 
regulate chromium (VI) in wastewaters from both segments of the Steel 
Finishing Subcategory. EPA proposed different limits for the carbon and 
alloy steel segment and the stainless steel segment of the subcategory. 
The following discussion pertains only to the stainless steel segment 
of the Steel Finishing Subcategory. Also, it does not apply to PSES 
standards, because EPA did not propose modification of the existing 
PSES standards for the Steel Finishing Subcategory.
    The proposed limitations and standards for the stainless steel 
segment are based upon two sets of chromium (VI) data, which are 
described in Section 12.2.6.2 of the Technical Development Document 
(EPA-821-B-00-011). EPA acquired the two sets of data through self-
monitoring performed by two different facilities. Prior to proposal, 
EPA lacked information from one facility regarding the chemical 
analytical method employed by that facility in analyzing the chromium 
(VI) data provided to EPA. Since proposal, EPA has received additional 
information about the chemical analytical methods for one set of these 
data and has verified that these data were determined by a method 
specified in or approved under 40 CFR Part 136, thus fulfilling one of 
EPA's criteria for data selection. Since proposal, EPA also has 
determined that the second set of data does not demonstrate effective 
performance of the model treatment technology. EPA believes that 
chromium (VI) reduction, if practiced properly, can consistently 
achieve effluent concentrations at or close to the minimum level of 
0.01 mg/L. This is supported by sampling data from two Metal Products 
and Machinery (MP&M) facilities and three iron and steel finishing 
facilities operating chromium (VI) reduction pretreatment systems. 
Consequently, EPA has removed the second data set from analysis.
    As a result of this change in the database, EPA recalculated the 
proposed limitations for BAT, NSPS, and PSNS for chromium (VI) in 
wastewater from the stainless steel segment of the Steel Finishing 
Subcategory. The limitations and standards that EPA is now considering 
are set forth in tables II.D.1, II.D.2 and II.D.3. The Agency believes 
that the data set used to establish theses limitations represents the 
best performing treatment system. We did not recalculate standards for 
PSES because EPA did not in the December, 2000 notice propose to revise 
the standards for existing indirect dischargers, but instead 
transferred them unchanged from the 1982 regulation, which did not set 
standards for chromium (VI). EPA is soliciting comment on this approach 
and on the recalculated limitations and standards.
    For BAT, Table II.D.1 presents the effluent limitations that would 
apply to discharges in the stainless steel segment for the Steel 
Finishing Subcategory for each operation as applicable.

E. Pretreatment Standards for Phenol for the Cokemaking Subcategory
    Generally, EPA establishes pretreatment standards for BAT 
pollutants that pass through publicly owned treatment works (POTWs) to 
waters of the U.S. or interfere with POTW operations or sludge disposal 
practices. The proposed regulation would establish PSES and PSNS for 
phenol for the byproducts segment of the Cokemaking Subcategory, based 
on the Agency's POTW pass-through analysis. To determine whether a 
pollutant passes through POTWs, EPA generally compares the average 
percentage of a pollutant removed by well-operated POTWs performing 
secondary treatment to the percentage of a pollutant removed by BAT 
treatment. When the median percentage removed nationwide by well-
operated POTWs is less than the median percentage removed by direct 
dischargers complying with the proposed BAT effluent limitations, EPA 
typically determines that the pollutant passes through.
    For the proposal, EPA calculated a POTW percent removal of 95% for 
phenol using data from the U.S. EPA Fate of Priority Pollutants in 
Publicly Owned Treatment Works (EPA 440/1-82/303, September 1982). The 
Agency calculated a cokemaking BAT percent removal of 99.9% for phenol 
based on data from iron and steel manufacturing facilities 
demonstrating BAT technology. Because the BAT percent removal is higher 
than the POTW percent removal, EPA concluded at the time of proposal 
that phenol in cokemaking process wastewater would pass through POTWs. 
However, in today's action EPA is considering finding that phenol does 
not pass through for the Cokemaking Subcategory of the proposed 
regulation. Instead, EPA is considering the following approach employed 
by EPA in the Organic Chemicals, Plastics, and Synthetic Fibers (OCPSF) 
guideline.
    As explained in the ``Supplement to the Development Document for 
Effluent Limitations and Guidelines and New Source Performance 
Standards for the Organic Chemicals, Plastics, and Synthetic Fibers 
Point Source Category'' (EPA 821-R-93-007), EPA determined that phenol 
is highly biodegradable and is treated by POTWs to the same non-detect 
levels (10 parts per billion (ppb) or 10 g/L) that the OCPSF 
direct dischargers achieve. EPA also observed that the direct 
dischargers had significantly higher influent concentrations than the 
POTWs, with the result that the OCPSF direct dischargers showed higher 
removals than the performance at the POTWs. EPA determined in the OCPSF 
rule that phenol did not pass through. EPA reasoned that application of 
the traditional approach to these facts would reflect the significant 
differences in influent concentrations rather than a real difference in 
the POTWs' ability to treat phenols.
    For the cokemaking subcategory in the Iron and Steel Point Source 
Category, EPA concluded at proposal that phenol passed through because 
the BAT percent removal was greater than 99.9 percent, while the POTW 
percent removal was 95 percent. Both the POTW and the cokemaking BAT 
facility were capable of treating phenol to a non-detectable level. 
However, as was the case for the OCPSF rulemaking, the influent 
concentrations of phenol at the BAT facility in the cokemaking 
subcategory are much higher than those at the POTWs. The average 
influent concentrations for phenol for the cokemaking BAT facility 
ranged from 48,000 g/L to greater than 400,000 g/L. 
On the other hand, the average influent phenol concentration for eight 
POTWs that passed the editing criteria was only 387 g/L, and 
the average effluent concentrations were 10 to 27 g/L 
corresponding to an average percent removal of 95.25 percent. Because 
the data for this subcategory resemble the data in OCPSF, EPA is 
considering employing the OCPSF approach here. Therefore, EPA is 
considering making a finding that phenol does not pass through because 
it is treated to essentially the same level by direct dischargers and 
POTWs.
    In addition, EPA conducted an additional POTW pass-through analysis 
following proposal using 1997-1998 data from a well-operated POTW 
performing secondary treatment on cokemaking process wastewater. This 
data is in the iron and steel rulemaking record. Using these 
alternative data, the Agency found that the POTW percent removal for 
phenol is 99.9%--a value equivalent to the BAT percent removal. Based 
upon this analysis, phenol would not pass through POTWs. Consequently, 
EPA is considering finding that phenol does not pass through for the 
Cokemaking Subcategory of the proposed regulation.
    EPA solicits comment on the results of the POTW pass-through 
analysis using the alternative data and whether the Agency should 
decide not to establish pretreatment standards for phenol for the 
Cokemaking Subcategory.
F. Alternate BAT, NSPS, PSES, and PSNS Limitations for the By-product 
Recovery Segment of the Cokemaking Subcategory
    EPA is requesting comment on an alternative approach to regulating 
discharges from by-product coke plants. Under this alternative, water 
added to optimize biological treatment processes would be regulated in 
the same manner as other flows added to cokemaking wastewaters (e.g., 
flows from wet

[[Page 10258]]

desulfurization systems and coke plant NESHAP controls). In the 
proposed regulation published on December 27, 2000, EPA included 50 
gallons per ton (gpt) of control water flow in the list of flow sources 
used to determine the baseline model production-normalized flow rate 
(PNF). EPA now recognizes that this control water is not used at all 
cokemaking biological treatment plants. Additionally, this flow is not 
necessary for the operation of physical/chemical treatment systems 
operated at a majority of indirect discharging facilities. Therefore, 
adding this flow to the baseline PNF would yield a higher PNF, and, 
consequently, less stringent limits than appear to be appropriate for 
many dischargers in the segment. For this reason, EPA is now 
considering not including this control water flow in the baseline 
cokemaking model PNFs. The result would be a decrease in the baseline 
cokemaking model PNF from 158 gpt to 108 gpt.
    In order to accommodate the facilities that actually add water to 
optimize biological treatment, EPA would make available an incremental 
flow allowance (expressed as a footnote) for the facilities. Those 
facilities using control water in the operation of their biological 
treatment systems would be allowed an increase in limitations not to 
exceed 46.3 percent. Facilities not using biological treatment for 
cokemaking wastewaters would not be eligible for the additional 
allowance. (EPA would maintain the other allowances EPA proposed in 
December 2000, which are printed below for the sake of completeness.)
    This alternative approach would not impact EPA's estimated cost of 
compliance. The Technical Development Document (EPA-821-B-00-011) 
presents the PNF development in section 7.3 and the methodology for 
costing in section 9.2.
    For this revision, EPA would base the new limitations on the 
pollutant concentrations established for the proposed rulemaking and a 
PNF of 108 gpt. The following tables show the by-products cokemaking 
limitations which EPA would promulgate under this approach. Table 
II.F.1 presents the BAT limitations. Table II.F.2 presents the NSPS 
limitations. Table II.F.3 presents the Physical Chemical Treatment PSES 
limitations. Table II.F.4 presents the Physical Chemical plus 
Biological Treatment PSES limitations. Table II.F.5 presents the 
Physical Chemical plus Biological Treatment PSNS limitations.

G. BPT Revision for By-Product Cokemaking Operations
    In the December 2000 notice, EPA proposed to recodify the current 
BPT for two cokemaking segments, merchant coke manufacturing and iron 
and steel coke manufacturing. We are now considering combining these 
two historical segments into one, named by-product coke manufacturing, 
because we now believe there is no meaningful distinction between these 
two segments. As a result, the iron and steel coke manufacturing plants 
would be subject to the same BPT limits as the merchant coke plants. 
(The current BPT limitations for merchant by-product cokemaking 
manufacturing plants are within 7 percent of those for iron and steel 
by-product cokemaking manufacturing plants.) The current BPT 
limitations for merchant coke plants that would apply to iron and steel 
coke manufacturing plant under this approach are shown in Table II.G.1:

    EPA believes there will be no significant adverse environmental 
impacts associated with this approach. Moreover, there would be no 
additional costs of compliance to achieve the resulting BPT. EPA 
solicits comments on this approach and solicits other options for 
consideration.

III. Corrections to Proposed Preamble and Regulation

A. General
    EPA is making the following corrections to the proposed regulation 
and accompanying preamble for the iron and steel manufacturing point 
source category.
    In reviewing the notice and proposed rulemaking (65 FR 81964), EPA 
discovered one error caused by a file conversion problem during Federal 
Register publication that occurred more than 100 times (starting on 
page 82000). In numerous instances on or after page 82000, words 
starting with the letters ``For'' (including the word ``For'' itself) 
were printed without the ``For.'' Therefore, ``Forming'' became 
``ming,'' ``Foreign'' became ``eign,'' ``Forging'' became ``ging,'' and 
sentences that started with ``For'' appeared without their first word. 
Although this action does not explicitly correct each and every such 
omission, EPA intends for the proposal to read logically and encourages 
reviewers to use the context of the sentence, and replace the missing 
letters as necessary. If reviewers have any questions on how to 
interpret inaccurately spelled words, please contact any of the EPA 
staff listed under the ``For Further Information Contact'' heading at 
the beginning of today's action.
B. Corrections to Preamble
    1. On page 81964, column 2, paragraph 2 under the heading ``How to 
Submit Comments,'' the second sentence should read ``Electronic 
comments must specify docket number W-00-25 and must be submitted as an 
ASCII, Word, or WordPerfect file avoiding the use of special characters 
and any form of encryption.''
    2. On page 81968, in the summary table, the entries for Subpart A, 
Cokemaking, (By -Product Recovery) should be as follows:
