SUPPLEMENTARY INFORMATION: On March 

28, 2022, EPA published a proposed 

rule titled ‘‘Control of Air Pollution 

from New Motor Vehicles: Heavy-Duty 

Engine and Vehicle Standards’’ (87 FR 

17414). The public comment for this 

proposed rule was scheduled to end on 

May 13, 2022. The Clean Air Act 

requires that the record of proceedings 

allowing oral presentation of data, 

views, and arguments on a proposed 

rule be kept open for 30 days after 

completion of the proceeding to provide 

an opportunity for submission of 

rebuttal and supplementary 

information. 42 U.S.C. 7607(d)(5). 

Because EPA held a third day of public 

hearing for this proposed rule, the final 

‘‘proceeding allowing oral presentation 

of data, views, and arguments,’’ was 

held on April 14, 2022. For this reason, 

the public comment period for this 

proposed rule is extended and will now 

end on May 16, 2022.

Intended Air Quality Redesignation for 

the 2008 Lead National Ambient Air 

Quality Standards; Canton, Ohio; Stark 

County, Ohio: Notice of Availability 

and Public Comment Period 

AGENCY: Environmental Protection 

Agency (EPA). 

ACTION: Notice of availability and public 

comment period. 

SUMMARY: The Environmental Protection 

Agency (EPA) is providing notice of our 

intent to redesignate a portion of 

Canton, Ohio in northeastern Stark 

County from ‘‘unclassifiable/ 

attainment’’ to ‘‘nonattainment’’ for the 

2008 National Ambient Air Quality 

Standards (NAAQS) for lead (Pb). The 

EPA’s intended redesignation of this 

portion of the Canton, Ohio area is 

based on recorded violations of the Pb 

NAAQS at Ohio Environmental 

Protection Agency’s (Ohio EPA) 

Republic Steel ambient air monitoring 

site located in Canton, Ohio, and 

additional relevant air quality 

information. If the redesignation to 

nonattainment is finalized, the state of 

Ohio would be required to undertake 

certain planning requirements to reduce 

Pb concentrations within this 

nonattainment area, including, but not 

limited to, the requirement to submit 

within 18 months of redesignation, a 

revision to the Ohio state 

implementation plan (SIP) that provides 

for attainment of the Pb standards as 

expeditiously as practicable, but no later 

than 5 years after the date of 

redesignation to nonattainment. 

Notice is hereby given that the EPA 

(Agency) has posted on our public 

electronic docket and internet website 

the intended redesignation for relevant 

portion of the Canton, Ohio (Stark 

County, OH) area under the 2008 Pb 

NAAQS. The EPA invites the public to 

review and provide input on our 

intended redesignation during the 

comment period specified in the DATES

section. The EPA notified the state of 

Ohio of our intended redesignation 

action on or about April 26, 2022. The 

EPA intends to make its final 

redesignation determination for the 

Canton, Ohio area approximately 240 

days from the date the Agency notified 

the state of its intended designation, 

that is, in December 2022. 

DATES: Comments must be received on 

or before June 2, 2022. Please refer to 

SUPPLEMENTARY INFORMATION for 

additional information on the comment 

period.

I. Purpose of Action and Instructions 

for Submitting Public Comments 

The purpose of this notice of 

availability is to solicit input from 

interested parties on the EPA’s 

notification to the state of Ohio of our 

intended redesignation determination 

for the Canton, Ohio area (Stark County, 

Ohio) for the 2008 Pb NAAQS. The 

EPA’s notification letter and the 

supporting technical analyses can be 

found at https://www.epa.gov/leaddesignations and also in the public 

docket for this action at https://

www.regulations.gov under Docket ID 

No. EPA–HQ–OAR–2022–0195. 

The EPA invites public input 

regarding the Canton, OH area during 

the 30-day comment period provided in 

this notice. To receive full 

consideration, input from the public 

must be submitted to the docket by June 

2, 2022. This notice and opportunity for 

public comment does not affect any 

rights or obligations of any state, or 

tribe, or of the EPA, which might 

otherwise exist pursuant to the CAA 

section 107(d). 

CAA section 107(d)(3) provides a 

process for air quality redesignations 

that involves recommendations by 

affected states, territories, and tribes to 

the EPA and responses from the EPA to 

those parties, prior to the EPA 

promulgating final area redesignation 

decisions. The EPA is not required 

under the CAA section 107(d)(3) to seek 

public comment during the 

redesignations process, but we are 

electing to do so for this area with 

respect to the 2008 Pb NAAQS to gather 

additional information for the EPA to 

consider before making final 

redesignation decisions for the specific 

area addressed. 

1. Submitting CBI. Do not submit CBI 

information to the EPA through https:// 

www.regulations.gov or email. Clearly

• Explain why you agree or disagree; 

suggest alternatives and substitute 

language for your requested changes. 

II. The 2008 Pb NAAQS 

Under section 109 of the Clean Air 

Act (CAA or Act), the EPA has 

established primary and secondary 

NAAQS for certain pervasive air 

pollutants (referred to as ‘‘criteria 

pollutants’’) and conducts periodic 

reviews of the NAAQS to determine 

whether they should be revised or 

whether new NAAQS should be 

established. The primary NAAQS 

represent ambient air quality standards, 

the attainment and maintenance of 

which the EPA has determined, 

including a margin of safety, are 

requisite to protect the public health. 

The secondary NAAQS represent 

ambient air quality standards, the 

attainment and maintenance of which 

the EPA has determined are requisite to 

protect the public welfare from any 

known or anticipated adverse effects 

associated with the presence of such air 

pollutant in the ambient air. 

Under the CAA, the EPA must 

establish NAAQS for criteria pollutants, 

including Pb. Lead is generally emitted 

in the form of particles that are 

deposited in water, soil, and dust. 

People may be exposed to Pb by 

inhaling it or by ingesting PbVerDate Sep<11>2014 16:47 May 02, 2022 Jkt 256001 PO 00000 Frm 00006 Fmt 4702 Sfmt 4702 E:\FR\FM\03MYP1.SGM 03MYP1

contaminated food, water, soil, or dust. 

Once in the body, Pb is quickly 

absorbed into the bloodstream and can 

result in a broad range of adverse health 

effects including damage to the central 

nervous system, cardiovascular 

function, kidneys, immune system, and 

red blood cells. Children are 

particularly vulnerable to Pb exposure, 

in part because they are more likely to 

ingest Pb and in part because their stilldeveloping bodies are more sensitive to 

the effects of Pb. The harmful effects to 

children’s developing nervous systems 

(including their brains) arising from Pb 

exposure may include intelligence 

quotient (IQ) 1 loss, poor academic 

achievement, long-term learning 

disabilities, and an increased risk of 

delinquent behavior.2

The EPA first established primary and 

secondary Pb standards in 1978 at 1.5 

micrograms per cubic meter (mg/m3) as 

a quarterly average.3 Based on new 

health and scientific data, on October 

15, 2008, the EPA revised the federal Pb 

standards to 0.15 mg/m3 and revised the 

averaging time for the standards.4 Since 

the primary and secondary Pb standards 

are the same, we refer to them hereafter 

in this document using the singular Pb 

standard or NAAQS. A violation of the 

2008 Pb NAAQS occurs if any 

arithmetic 3-month mean concentration 

is greater than 0.15 mg/m3.5

III. Designations for the 2008 Pb 

NAAQS 

Following promulgation of any new 

or revised NAAQS, the EPA is required 

by CAA section 107(d) to designate 

areas throughout the nation as attaining 

or not attaining the NAAQS. The EPA 

initially designated all areas of the 

country as ‘‘unclassifiable,’’ 

‘‘unclassifiable/attainment,’’ or 

‘‘nonattainment’’ for the 2008 Pb 

NAAQS in two rounds on November 16, 

2010, and November 8, 2011. In the 

November 8, 2011, action, the EPA 

designated Stark County, along with the 

remaining areas of Ohio, as 

unclassifiable/attainment.6

Pursuant to CAA section 107(d), the 

EPA must designate as ‘‘nonattainment’’ 

those areas that violate the NAAQS and 

those nearby areas that contribute to 

violations. Once an area has been 

designated, the EPA Administrator, 

under CAA section 107(d)(3), may at 

any time notify a state that a designation 

should be revised. 42 U.S.C. 7407(d)(3). 

In 2021, the EPA determined that 

quality-assured, certified monitoring 

data collected during 2017–2020 at the 

Ohio EPA ambient air monitoring site 

located at 3150 Georgetown Road NE in 

Canton, Ohio (Republic Steel ambient 

air monitoring site), showed that the 

area was violating the Pb NAAQS. 

Accordingly, consistent with CAA 

section 107(d)(3)(A), the EPA notified 

the Governor of Ohio in a letter dated 

April 26, 2022, of our intent to 

redesignate the relevant portion of the 

Canton, Ohio area as ‘‘nonattainment’’ 

for the 2008 Pb NAAQS. 

IV. Applicable Regulatory Provisions 

A determination of whether an area’s 

air quality meets applicable standards is 

generally based upon the most recent 3 

years of complete, quality-assured data 

gathered at established state and local 

air monitoring stations (SLAMS) and 

entered into the EPA’s Air Quality 

System (AQS) database.7 Data from 

ambient air monitors operated by state 

and local agencies in compliance with 

the EPA monitoring requirements must 

be submitted to AQS.8 Monitoring 

agencies annually certify that these data 

are accurate to the best of their 

knowledge.9 All data are reviewed to 

determine the area’s air quality status 

for Pb in accordance with 40 CFR part 

50, Appendix R. 

Under the EPA regulations in 40 CFR 

50.16 and in accordance with 40 CFR 

part 50 Appendix R, the 2008 Pb 

NAAQS is met when the design value 

is less than or equal to 0.15 mg/m3 at 

each eligible monitoring site within the 

area. The Pb design value at each 

eligible monitoring site is the maximum 

valid 3-month arithmetic mean Pb 

concentration from the 38-month period 

consisting of the most recent 3-year 

calendar period plus two previous 

months. The 3-month mean Pb 

concentrations are rounded to the 

nearest hundredth mg/m3 for 

comparison to the NAAQS. Data 

completeness requirements for a given 

3-month period are met if the average of 

the data capture rate of the three 

constituent monthly means is greater 

than or equal to 75 percent.10

V. Monitoring Network Considerations 

Section 110(a)(2)(B)(i) of the CAA 

requires states to establish and operate 

air monitoring networks to compile data 

on ambient air quality for all criteria 

pollutants. The EPA’s monitoring 

requirements are specified by regulation 

in 40 CFR part 58. These requirements 

are applicable to state, and where 

delegated, local air monitoring agencies 

that operate criteria pollutant monitors. 

The regulations in 40 CFR part 58 

establish specific requirements for 

operating air quality surveillance 

networks to measure ambient 

concentrations of Pb, including 

requirements for measurement methods, 

network design, quality assurance 

procedures, and in the case of large 

urban areas, the minimum number of 

monitoring sites designated as SLAMS. 

In sections 4.4 and 4.5 of Appendix D 

to 40 CFR part 58, the EPA specifies 

minimum monitoring requirements for 

Pb, respectively, to operate at SLAMS. 

SLAMS produce data that are eligible 

for comparison with the NAAQS, and 

therefore, the monitor must be an 

approved federal reference method 

(FRM), federal equivalent method 

(FEM), or approved regional method 

(ARM) monitor. 

The minimum number of required Pb 

SLAMS is described in section 4.5 of 

Appendix D to 40 CFR part 58. There 

must be at least one source-oriented 

SLAMS site located to measure the 

maximum Pb concentration in ambient 

air resulting from each non-airport Pb 

source that emits 0.50 or more tons per 

year (tpy) and from each airport that 

emits 1.0 tpy or more based on either 

the most recent National Emission 

Inventory (NEI) or other scientifically 

justifiable methods and data. 

According to the 2017 NEI, one source 

in Stark County, Ohio exceeded the 0.50 

tpy threshold and therefore required 

source-oriented Pb monitoring: The 

Republic Steel plant located at 2633 

Eighth Street NE in Canton, Ohio 

(Republic Steel).11 Republic Steel is a 

steel manufacturer that manufactures 

leaded steel and other steel products.

VI. Canton, Ohio Ambient Air 

Monitoring Site 

On June 6, 2017, an ambient air 

monitoring site was installed and began 

operating in Stark County to measure 

concentrations of Pb and other toxic 

metals. Ohio EPA, through its 

partnership with the Canton City Public 

Health Department, installed a special 

purpose monitor to meet the 

requirements of a permit 12 issued on 

December 12, 2016, to Republic Steel as 

part of operational changes made to its 

plant at 2633 Eighth Street NE in 

Canton, Ohio. 

In April 2019, Ohio EPA converted 

the designated primary Pb sampler at 

the Republic Steel ambient air 

monitoring site from a special purpose 

monitor (SPM) to a SLAMS monitor. 

The conversion was made as a result of 

Ohio EPA’s 2017 emissions inventory, 

which indicated that Republic Steel’s Pb 

emissions were at 0.81 tpy, which 

exceeds the source-oriented 0.50 tpy 

monitoring threshold in 40 CFR part 58 

Appendix D. The EPA requires SLAMS 

monitors to collect Pb samples at a 

minimum frequency of 1-in-6 days and 

those data be reported to the EPA’s 

AQS. Ohio EPA continued to also 

collect SPM samples to sample air 

quality specifically during leaded 

production at the Republic Steel plant; 

however, the SPM monitoring data is 

not reported to the EPA’s AQS. Ohio 

EPA posts the SLAMS and SPM data on 

its website.13

Two ambient air quality monitors 

(Parameter Occurrence Code (POC 1, 

POC 4) at the Republic Steel ambient air 

monitoring site measure ambient 

concentrations on a microscale level of 

0 to 100 meters with a staggered 

schedule. POC 1 operates on the EPA 

sampling schedule of 1-in-6 days, and 

POC 4 operates on a randomized 

schedule. The POC is used to 

distinguish different instruments that 

measure the same parameter at the same 

site. 

VII. Pb Data Considerations 

In accordance with Appendix R to 40 

CFR part 50, compliance with the Pb 

NAAQS is determined based on data 

from 36 consecutive valid 3-month 

periods (i.e., 38 months, or a 3-year 

calendar period and the preceding 

November and December). As detailed 

in 40 CFR part 50 Appendix R section 

4(c)(i), a 3-month mean Pb value is 

determined to be valid (i.e., meets data 

completeness requirements) if the 

average of the data capture rate of the 

three constituent monthly means is 

greater than or equal to 75 percent. 

Under 40 CFR 58.15, monitoring 

agencies must certify, on an annual 

basis, data collected at all SLAMS and 

at all FRM, FEM, and ARM special 

purpose monitor stations that meet the 

EPA quality assurance requirements. In 

doing so, monitoring agencies must 

certify that the previous year of ambient 

concentration and quality assurance 

data are completely submitted to AQS 

and that the ambient concentration data 

are accurate to the best of their 

knowledge. Ohio EPA annually certifies 

that the data it submits to AQS are 

quality-assured, including data 

collected by Ohio EPA at the Republic 

Steel monitoring site. 

We have evaluated the completeness 

of these data in accordance with the 

requirements of 40 CFR part 50 

Appendix R. The data collected by Ohio 

EPA at the Republic Steel ambient air 

monitoring site meet this completeness 

criterion for each 3-month period from 

November 2018–December 2020. 

Table 1 presents a summary of the 

latest available quality-assured Pb 

monitoring data from the Republic Steel 

ambient air monitoring site. A map 

showing the location of the monitor is 

included in the EPA’s Technical 

Support Document (EPA TSD),

The EPA considered the Pb NAAQS 

design value for the Republic Steel 

ambient air monitoring site in Stark 

County by assessing the most recent 3 

consecutive years (i.e., 2018–2020) and 

two previous months of quality-assured, 

certified ambient air quality data in the 

EPA’s AQS using data from FRM 

and/or FEM monitors that are sited and 

operated in accordance with 40 CFR 

parts 50 and 58. Data collected at the 

Republic Steel monitoring site indicate 

that the 2018–2020 design value 

representative of the Stark County area 

is 0.21 mg/m3. With a design value of 

0.21 mg/m3, the Republic Steel ambient 

air monitoring site shows a violation of 

the 2008 Pb NAAQS of 0.15 mg/m3 for 

2018–2020. 

VIII. The EPA’s Intended Decision To 

Address Monitored Pb Violations in the 

Canton, Ohio Area Through 

Redesignation 

The CAA provides the EPA with the 

authority to change the designation of, 

or ‘‘redesignate,’’ areas in light of 

changes in circumstances. More 

specifically, the EPA has the authority 

under CAA section 107(d)(3) to 

redesignate areas (or portions thereof) 

on the basis of air quality data, planning 

and control considerations, or any other 

air quality-related considerations. Stark 

County shows a violation of the 2008 Pb 

NAAQS based on data collected during 

2018–2020, and, therefore, under CAA 

section 107(d)(3), the EPA can notify the 

state of its intent to redesignate to 

nonattainment all or some of Stark 

County and possibly additional areas in 

surrounding counties. In this action, 

EPA is providing notice of its intent to 

redesignate only part of Stark County to 

nonattainment. 

Under CAA section 107(d)(3), the EPA 

Administrator may at any time notify 

the Governor of any State that available 

information indicates that the 

designation of any area or portion of an 

area within the State should be revised. 

For purposes of this intended 

redesignations action, EPA is following 

the same analytical steps applied in the 

initial area designations process 

following promulgation of a new or 

revised NAAQS. That is, under CAA 

section 107(d)(1)(A)(i), the statutory

authority for initial area designations, 

EPA must designate as nonattainment 

any area that violates the NAAQS and 

any nearby area that contributes to 

ambient air quality in the violating area. 

Air quality data from 2018–2020 

indicate that ambient Pb concentrations 

in Stark County do not meet the 

NAAQS, and, therefore, some area in 

Stark County and possibly additional 

areas in surrounding counties must be 

redesignated as nonattainment. The 

absence of monitored violations in 

nearby counties is not a sufficient 

reason to eliminate nearby counties as 

candidates for nonattainment status. 

The technical analysis identified the 

monitor that was showing a violation of 

the standards (‘‘violating monitor’’) and 

evaluated nearby areas for contributions 

to ambient Pb concentrations in the 

area. To determine the boundaries of an 

area where violations support a 

nonattainment designation, the 2008 

Final Rule for the Pb NAAQS adopted 

guidance (2008 EPA Pb Guidance) 

stated that the perimeter of a county 

containing the violating monitor would 

be the initial presumptive boundary for 

nonattainment areas. If the intended 

boundaries are smaller than the full 

county, the EPA requires a 

demonstration to show that violations 

are not occurring in the excluded 

portions of the county and that the 

excluded portions are not source areas 

that contribute to the observed 

violations. To justify establishing either 

a larger or smaller area, the 2008 EPA 

Pb Guidance indicated the following 

eight factors should be considered.14

(1) Air quality in potentially included 

versus excluded areas; 

(2) Emissions in areas potentially 

included versus excluded from the 

nonattainment area; 

(3) Level of control of emission 

sources; 

(4) Population density and degree of 

urbanization including commercial 

development in included versus 

excluded areas; 

(5) Expected growth (including extent, 

pattern, and rate of growth); 

(6) Meteorology (weather/transport 

patterns); 

(7) Geography/topography (mountain 

ranges or other air basin boundaries); 

and 

(8) Jurisdictional boundaries (e.g., 

counties, air districts, reservations, etc.). 

In addition to an analysis of the eight 

factors above, states can choose to 

recommend Pb nonattainment 

boundaries by using one, or a 

combination of the following 

techniques: 

• Qualitative analysis; 

• Spatial interpolation of air quality 

monitoring data; or 

• Air quality simulation by 

dispersion modeling.15

The EPA’s detailed evaluation of the 

violating monitoring site, contributing 

sources, and intended area boundaries 

based on the weight of evidence of the 

previously identified factors is included 

in the TSD, which is located in the 

docket for this intended redesignations 

action. EPA’s intended boundaries of 

the relevant area encompass the 

portions of Stark County that are 

bounded on the north by State Route 

OH–153 (12th Street NE; Mahoning 

Road), on the east by Broadway Avenue, 

on the south by State Route OH–172 

(Tucarawas Street E; Lincoln Street E), 

and the west by State Route OH–43— 

Northbound (Cherry Avenue NE). A 

map showing the boundaries of our 

intended nonattainment area for Canton, 

Ohio is included in the TSD.

Hawaii: Authorization of State 

Hazardous Waste Management 

Program Revisions 

AGENCY: Environmental Protection 

Agency (EPA). 

ACTION: Proposed action/decision/ 

authorization. 

SUMMARY: The Environmental Protection 

Agency (EPA) is proposing to authorize 

changes to Hawaii’s hazardous waste 

program under the Resource 

Conservation and Recovery Act (RCRA). 

These changes were outlined in an 

application to the EPA and correspond 

to certain federal rules promulgated 

between July 1, 2016 and June 30, 2020 

(also known as RCRA Clusters XXV to 

XXVIII) and for authorization of stateinitiated changes that are equivalent to 

or more stringent than the federal 

program. The EPA reviewed Hawaii’s 

application and has determined that 

these changes satisfy all requirements 

needed to qualify for final authorization. 

Elsewhere, in the ‘‘Rules and 

Regulations’’ section of this Federal 

Register, we are authorizing Hawaii for 

these changes as a direct final 

authorization without a prior proposed 

action. If we receive no adverse 

comment, we will not take further 

action on this proposed authorization. 

DATES: Comments must be received on 

or before June 2, 2022. 

ADDRESSES: Submit your comments to 

EPA, identified by Docket ID No. EPA–
