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.

III. Corrections to Proposed Preamble and Regulation

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 Start Printed Page 10254of 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

Process wastewater sourceMaximum daily 1Maximum monthly average 1
(a) Basic oxygen furnaces (1) semi-wet air pollution controls TSS0.01250.00417
1 Pounds per ton of product.

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.

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 μg/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 μg/L to greater than 400,000 μg/L. On the other hand, the average influent phenol concentration for eight POTWs that passed the editing criteria was only 387 μg/L, and the average effluent concentrations were 10 to 27 μg/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 Start Printed Page 10258desulfurization 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: Start Printed Page 10261

Subpart A. Cokemaking (By-Product Recovery)BAT/NSPSBAT-3tar removal, equalization, ammonia stripping, temperature control, equalization, single-stage biological treatment with nitrification, alkaline chlorination, and sludge dewatering.
PSES/PSNSPSES-3tar removal, equalization, ammonia stripping, temperature control, equalization, single-stage biological treatment with nitrification.
co-proposed PSESPSES-1tar removal, equalization, ammonia PSES stripping.

3. On page 81972, column 1, the sentence beginning in the last line should be “See Appendix A of the Development Document for the Proposed Effluent Limitations and Guidelines for the Iron and Steel Manufacturing Point Source Category.”

6. On page 81979, column 1, end of line 40, the second sentence should be “From these data, EPA identified 71 POCs for the Cokemaking Subcategory: 4 conventionals, 1 non-conventional metal, 30 non-conventional organics, 10 other non-conventionals, 22 priority organics, 3 priority metals, and 1 other priority pollutant (total cyanide).”

Nevertheless, EPA selected these pollutants as POCs because they are widely present in cokemaking wastewater (each was detected at significant concentrations in 16 out of 16 untreated cokemaking wastewater samples collected) and are important indicators of biological treatment effectiveness. In addition, EPA selected nitrate/nitrite as a POC even though it failed the screening criteria because of its importance as an indicator of biological treatment effectiveness.”

8. On page 81979, column 2, beginning on line 51, the next two paragraphs should be: “EPA identified 27 POCs for the blast furnace segment of the Ironmaking Subcategory: 2 conventionals, 7 non-conventional metals, 1 non-conventional organic, 10 other non-conventionals, 6 priority metals, and 1 other priority pollutant (total cyanide). EPA could not evaluate TKN, WAD cyanide, and thiocyanate using the POC selection criteria because no method MLs were available at the time of the Agency's analysis. Nevertheless, EPA selected these pollutants as POCs because they are widely present in the blast furnace wastewater (each was detected in at least 60% of the untreated blast furnace wastewater samples collected).”

“EPA identified 65 POCs for the sintering segment of the Ironmaking Subcategory: 2 conventionals, 6 non-conventional metals, 24 non-conventional organics, 11 other non-conventionals, 11 priority organics, 10 priority metals, and 1 other priority pollutant (total cyanide).
