Abstract: This rule applies to all facilities that pickle steel using hydrochloric acid or regenerate hydrochloric acid, and are major sources or are part of a facility that is a major source. In general, all NESHAP standards require initial notifications, performance tests, and periodic reports by the owners/operators of the affected facilities. They are also required to maintain records of the occurrence and duration of any startup, shutdown, or malfunction in the operation of an affected facility, or any period during which the monitoring system is inoperative. These notifications, reports, and records are essential in determining compliance, and are required of all affected facilities subject to NESHAP. Any owner/operator subject to the provisions of this part shall maintain a file of these measurements, and retain the file for at least five years following the date of such measurements, maintenance reports, and records. All reports are sent to the delegated state or local authority. In the event that there is no such delegated authority, the reports are sent directly to the United States Environmental Protection Agency (EPA) regional office. Form Numbers: None. Respondents/affected entities: Steel pickling, hydrochloric acid process and regeneration facilities. Respondent’s obligation to respond: Mandatory. Estimated number of respondents: 100 (total). Frequency of response: Initially, occasionally and semiannually. Total estimated burden: 35,100 hours (per year). Burden is defined at 5 CFR 1320.3(b). Total estimated cost: $3,530,000 (per year), includes $10,600 annualized PO 00000 Frm 00026 Fmt 4703 Sfmt 4703 capital or operation & maintenance costs. Changes in the Estimates: The increase in burden and cost from the most recently approved ICR is due to an adjustment. It is not due to any program changes. During the 2012 RTR, EPA did not add additional requirements, other than reporting performance test results through the WebFIRE interface if the test methods used are those supported by the Electronic Reporting Tool (ERT). However, we updated the estimated number of average number of respondents subject to Subpart CCC from 72 to 100. The increase in the number of facilities results in an overall increase in the respondent and Agency burden and in O&M costs. Courtney Kerwin, Acting Director, Collection Strategies Division.

EPA’s final criteria documents for the ninety-four chemical pollutants, the response to views from the public on the draft criteria, and supporting information are also available on EPA’s Web site http://water.epa.gov/scitech/ swguidance/standards/criteria/health/. II. What are EPA’s recommended water quality criteria? EPA’s recommended water quality criteria are scientifically derived numeric values that EPA determines will generally protect aquatic life or human health from the adverse effects of pollutants in ambient water. Section 304(a)(1) of the Clean Water Act (CWA) requires EPA to develop and publish and, from time to time, revise criteria for protection of water quality and human health that accurately reflect the latest scientific knowledge. Water quality criteria developed under section 304(a) are based solely on data and scientific judgments on the relationship between pollutant concentrations and environmental and human health effects. Section 304(a) criteria do not reflect consideration of economic impacts or the technological feasibility of meeting pollutant concentrations in ambient water. EPA’s recommended Section 304(a) criteria provide technical information for states and authorized tribes to consider and use in adopting water quality standards that ultimately provide the basis for assessing water body health and controlling discharges of pollutants into waters of the United States. Under the CWA and its implementing regulations, states and authorized tribes are required to adopt water quality criteria to protect designated uses (e.g., public water supply, aquatic life, recreational use, or industrial use) and that are based on sound scientific rationale. EPA’s recommended criteria do not substitute for the CWA or regulations, nor are they regulations themselves. Thus, EPA’s recommended criteria do not impose legally binding requirements. States and authorized tribes have the discretion to adopt, where appropriate, other scientifically defensible water quality criteria that differ from these recommendations. Ultimately, however, such criteria must protect the designated use and be based on sound scientific rationale. III. Information on EPA’s 2015 final updated human health criteria EPA announces the availability of final updated national recommended water quality criteria for the protection of human health for ninety-four chemical pollutants. These revisions are based on EPA’s existing methodology for deriving human health criteria in Methodology for Deriving Ambient Water Quality Criteria for the Protection of Human Health (2000) (EPA–822–B– 00–004, October 2000). The methodology describes EPA’s approach for deriving national recommended water quality criteria for the protection of human health.

EPA updated the human health criteria using externally peerreviewed information sources. On May 13, 2014, EPA announced the availability of the draft updated human health criteria in the Federal Register notice ‘‘Updated National Recommended Water Quality Criteria for the Protection of Human Health’’ (79 FR 27303) and announced that written views would be accepted from the public until July 14, 2014. In response to stakeholder requests, on June 23, 2014, EPA announced in the Federal Register (79 FR 35545) an extension of the public comment period for an additional 30 days, until August 13, 2014. EPA reviewed and considered all public comments received and prepared responses to those comments. EPA developed chemical-specific science documents for each of the ninety-four chemical pollutants. These documents detail the latest scientific information supporting the final human health criteria, particularly the updated toxicity and exposure input values. A fact sheet and a summary of updated input parameters (e.g., health toxicity values, bioaccumulation factors) used to derive the final updated criteria are provided. All these documents, including EPA’s responses to views received during the comment period, are available on EPA’s Web site at http://water.epa.gov/scitech/ swguidance/standards/criteria/health/. IV.

States and authorized tribes must adopt water quality criteria that protect designated uses. 40 CFR 131.11(a)(1). Criteria must be based on a sound scientific rationale and contain sufficient parameters or constituents to protect the designated uses. Id. Criteria may be expressed in either narrative or numeric form. EPA’s regulations provide that states and authorized tribes should adopt numeric water quality criteria based on: (1) EPA’s recommended section 304(a) criteria; or (2) EPA’s recommended section 304(a) criteria modified to reflect sitespecific conditions; or (3) Other scientifically defensible methods. (40 CFR 131.11(b)). It is important for states and authorized tribes to consider any new or updated section 304(a) recommended criteria as part of their triennial review process to ensure that state or tribal water quality criteria reflect sound science and protect applicable designated uses. EPA recently proposed revisions to its water quality standards regulations that would, if finalized without substantive change, require states during their triennial reviews to consider new or updated section 304(a) recommended criteria and, if they do not adopt new or revised criteria for such pollutants, provide an explanation to EPA and the public as to why the state did not do so. These final updated section 304(a) human health criteria recommendations supersede EPA’s previous recommendations. Dated: June 22, 2015. Kenneth J.

Final Updated Ambient Water Quality Criteria for the Protection 
of Human Health

AGENCY: Environmental Protection Agency (EPA).

ACTION: Notice of availability.

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

SUMMARY: The Environmental Protection Agency (EPA) announces the final 
updated recommended ambient water quality criteria for the protection 
of human health for ninety-four chemical pollutants to reflect the 
latest scientific information and implementation of existing EPA 
policies found in Methodology for Deriving Ambient Water Quality 
Criteria for the Protection of Human Health (2000). The EPA issued the 
draft updated human health criteria on May 13, 2014 and accepted 
written views from the public until August 13, 2014. The EPA prepared 
responses to those public comments. The EPA's recommended ambient water 
quality criteria for the protection of human health provide technical 
information for states and authorized tribes to establish water quality 
standards (i.e., criteria) to protect human health under the Clean 
Water Act. These final 2015 updated section 304(a) human health 
criteria recommendations supersede EPA's previous recommendations.

II. What are EPA's recommended water quality criteria?

    EPA's recommended water quality criteria are scientifically derived 
numeric values that EPA determines will generally protect aquatic life 
or human health from the adverse effects of pollutants in ambient 
water.
    Section 304(a)(1) of the Clean Water Act (CWA) requires EPA to 
develop and publish and, from time to time, revise criteria for 
protection of water quality and human health that accurately reflect 
the latest scientific knowledge. Water quality criteria developed under 
section 304(a) are based solely on data and scientific judgments on the 
relationship between pollutant concentrations and environmental and 
human health effects. Section 304(a) criteria do not reflect 
consideration of economic impacts or the technological feasibility of 
meeting pollutant concentrations in ambient water.
    EPA's recommended Section 304(a) criteria provide technical 
information for states and authorized tribes to consider and use in 
adopting water quality standards that ultimately provide the basis for 
assessing water body health and controlling discharges of pollutants 
into waters of the United States. Under the CWA and its implementing 
regulations, states and authorized tribes are required to adopt water 
quality criteria to protect designated uses (e.g., public water supply, 
aquatic life, recreational use, or industrial use) and that are based 
on sound scientific rationale. EPA's recommended criteria do not 
substitute for the CWA or regulations, nor are they regulations 
themselves. Thus, EPA's recommended criteria do not impose legally 
binding requirements. States and authorized tribes have the discretion 
to adopt, where appropriate, other scientifically defensible water 
quality criteria that differ from these recommendations. Ultimately, 
however, such criteria must protect the designated use and be based on 
sound scientific rationale.

III. Information on EPA's 2015 final updated human health criteria

    EPA announces the availability of final updated national 
recommended water quality criteria for the protection of human health 
for ninety-four chemical pollutants. These revisions are based on EPA's 
existing methodology for deriving human health criteria in Methodology 
for Deriving Ambient Water Quality Criteria for the Protection of Human 
Health (2000) (EPA-822-B-00-004, October 2000). The methodology 
describes EPA's approach for deriving national recommended water 
quality criteria for the protection of human health. Table 1 presents 
the updated human health criteria for ninety-four chemical pollutants.

    The revision of these criteria is a systematic update of EPA's 
national recommended human health criteria. EPA previously described 
its process for publishing revised criteria [see National Recommended 
Water Quality Criteria--Correction (64 FR 19781; or EPA-822-Z-99-001) 
or the Federal Register Notice for EPA's 2000 Methodology (65 FR 
66444)]. EPA updated the human health criteria using externally peer-
reviewed information sources.
    On May 13, 2014, EPA announced the availability of the draft 
updated human health criteria in the Federal Register notice ``Updated 
National Recommended Water Quality Criteria for the Protection of Human 
Health'' (79 FR 27303) and announced that written views would be 
accepted from the public until July 14, 2014. In response to 
stakeholder requests, on June 23, 2014, EPA announced in the Federal 
Register (79 FR 35545) an extension of the public comment period for an 
additional 30 days, until August 13, 2014. EPA reviewed and considered 
all public comments received and prepared responses to those comments.
    EPA developed chemical-specific science documents for each of the 
ninety-four chemical pollutants. These documents detail the latest 
scientific information supporting the final human health criteria, 
particularly the updated toxicity and exposure input values. A fact 
sheet and a summary of updated input parameters (e.g., health toxicity 
values, bioaccumulation factors) used to derive the final updated 
criteria are provided. All these documents, including EPA's responses 
to views received during the comment period, are available on EPA's Web 
site at http://water.epa.gov/scitech/swguidance/standards/criteria/health/.

IV. What is the relationship between EPA's 2015 final updated human 
health criteria and state or tribal water quality standards?

    Section 303(a)-(c) of the CWA requires states and authorized tribes 
to adopt water quality standards for their waters. As part of the water 
quality standards triennial review process set forth in section 303(c) 
of the CWA, states and authorized tribes are required to review and 
revise, if appropriate, their water quality standards at least once 
every three years.
    States and authorized tribes must adopt water quality criteria that 
protect designated uses. 40 CFR 131.11(a)(1). Criteria must be based on 
a sound scientific rationale and contain sufficient parameters or 
constituents to protect the designated uses. Id. Criteria may be 
expressed in either narrative or numeric form. EPA's regulations 
provide that states and authorized tribes should adopt numeric water 
quality criteria based on:
    (1) EPA's recommended section 304(a) criteria; or
    (2) EPA's recommended section 304(a) criteria modified to reflect 
site-specific conditions; or
    (3) Other scientifically defensible methods. (40 CFR 131.11(b)).
    It is important for states and authorized tribes to consider any 
new or updated section 304(a) recommended criteria as part of their 
triennial review process to ensure that state or tribal water quality 
criteria reflect sound science and protect applicable designated uses. 
EPA recently proposed revisions to its water quality standards 
regulations that would, if finalized without substantive change, 
require states during their triennial reviews to consider new or 
updated section 304(a) recommended criteria and, if they do not adopt 
new or revised criteria for such pollutants, provide an explanation to 
EPA and the public as to why the state did not do so. These final 
updated section 304(a) human health criteria recommendations supersede 
EPA's previous recommendations.
