contact Mr. Aaron Yeow, Designated 

Federal Officer (DFO), SAB Staff Office, 

by telephone at (202) 564–2050 or via

information concerning the CASAC, as 

well as any updates concerning the 

meetings announced in this notice can

https://casac.epa.gov. 

SUPPLEMENTARY INFORMATION: 

Background: The CASAC was 

established pursuant to the Clean Air 

Act (CAA) Amendments of 1977, 

codified at 42 U.S.C. 7409(d)(2), to 

review air quality criteria and NAAQS 

and recommend to the EPA 

Administrator any new NAAQS and 

revisions of existing criteria and 

NAAQS as may be appropriate. The 

52674 Federal Register / Vol. 86, No. 181 / Wednesday, September 22, 2021 / Notices 

CASAC shall also: Advise the EPA 

Administrator of areas in which 

additional knowledge is required to 

appraise the adequacy and basis of 

existing, new, or revised NAAQS; 

describe the research efforts necessary 

to provide the required information; 

advise the EPA Administrator on the 

relative contribution to air pollution 

concentrations of natural as well as 

anthropogenic activity; and advise the 

EPA Administrator of any adverse 

public health, welfare, social, economic, 

or energy effects which may result from 

various strategies for attainment and 

maintenance of such NAAQS. As 

amended, 5 U.S.C., App. Section 

109(d)(1) of the Clean Air Act (CAA) 

requires that EPA carry out a periodic 

review and revision, as appropriate, of 

the air quality criteria and the NAAQS 

for the six ‘‘criteria’’ air pollutants, 

including PM. 

The CASAC is a Federal Advisory 

Committee chartered under the Federal 

Advisory Committee Act (FACA), 5 

U.S.C., App. 2, and conducts business 

in accordance with FACA and related 

regulations. The CASAC and the 

CASAC PM Panel will comply with the 

provisions of FACA and all appropriate 

SAB Staff Office procedural policies. 

Pursuant to FACA and EPA policy, 

notice is hereby given that the CASAC 

PM Panel will hold a public meeting to 

receive a briefing from EPA on updates 

to the science assessment and updates 

to the policy assessment that support 

the agency’s reconsideration of the 2020 

PM NAAQS and a public meeting for 

the panel to peer review the agency’s 

science assessment updates and policy 

assessment updates. 

Technical Contacts: Any technical 

questions concerning EPA’s updates to 

the PM science assessment should be 

directed to Mr. Jason Sacks 

(sacks.jason@epa.gov). Any technical 

questions concerning EPA’s updates to 

the PM policy assessment should be 

directed to Dr. Lars Perlmutt 

(perlmutt.lars@epa.gov). 

Availability of Meeting Materials: 

Prior to the meeting, the review 

documents, agenda and other materials 

will be accessible on the CASAC 

website: https://casac.epa.gov. 

Procedures for Providing Public Input: 

Public comment for consideration by 

EPA’s federal advisory committees and 

panels has a different purpose from 

public comment provided to EPA 

program offices. Therefore, the process 

for submitting comments to a federal 

advisory committee is different from the 

process used to submit comments to an 

EPA program office. Federal advisory 

committees and panels, including 

scientific advisory committees, provide 

independent advice to EPA. Members of 

the public can submit relevant 

comments on the topic of this advisory 

activity, including the charge to the 

CASAC and the EPA review documents, 

and/or the group conducting the 

activity, for the CASAC to consider as 

it develops advice for EPA. Input from 

the public to the CASAC will have the 

most impact if it provides specific 

scientific or technical information or 

analysis for CASAC to consider or if it 

relates to the clarity or accuracy of the 

technical information. Members of the 

public wishing to provide comment 

should follow the instructions below to 

submit comments. 

Oral Statements: Individuals or 

groups requesting an oral presentation 

during the public meeting will be 

limited to three minutes. Each person 

making an oral statement should 

consider providing written comments as 

well as their oral statement so that the 

points presented orally can be expanded 

upon in writing. Interested parties 

should contact Mr. Aaron Yeow, DFO, 

in writing (preferably via email) at the 

contact information noted above by 

November 10, 2021, to be placed on the 

list of public speakers. 

Written Statements: Written 

statements will be accepted throughout 

the advisory process; however, for 

timely consideration by CASAC 

members, statements should be 

supplied to the DFO (preferably via 

email) at the contact information noted 

above by November 10, 2021. It is the 

SAB Staff Office general policy to post 

written comments on the web page for 

the advisory meeting or teleconference. 

Submitters are requested to provide an 

unsigned version of each document 

because the SAB Staff Office does not 

publish documents with signatures on 

its websites. Members of the public 

should be aware that their personal 

contact information, if included in any 

written comments, may be posted to the 

CASAC website. Copyrighted material 

will not be posted without explicit 

permission of the copyright holder. 

Accessibility: For information on 

access or services for individuals with 

disabilities, please contact Mr. Aaron 

Yeow at (202) 564–2050 or yeow.aaron@

epa.gov. To request accommodation of a 

disability, please contact the DFO, at the 

contact information noted above, 

preferably at least ten days prior to each 

meeting, to give EPA as much time as 

possible to process your request.

Deputy Director, Science Advisory Board Staff 

Office.

Administration of Cross-State Air 

Pollution Rule Trading Program 

Assurance Provisions for 2020 Control 

Periods 

AGENCY: Environmental Protection 

Agency (EPA). 

ACTION: Notice of data availability. 

SUMMARY: The Environmental Protection 

Agency (EPA) is providing notice of the 

availability of data on the 

administration of the assurance 

provisions of the Cross-State Air 

Pollution Rule (CSAPR) trading 

programs for the control periods in 

2020. Total emissions of nitrogen oxides 

(NOX) reported by Mississippi and 

Missouri units participating in the 

CSAPR NOX Ozone Season Group 2 

Trading Program during the 2020 

control period exceeded the respective 

states’ assurance levels under the 

program. Data demonstrating the 

exceedances and EPA’s final 

calculations of the amounts of 

additional allowances that the owners 

and operators of certain Mississippi and 

Missouri units must surrender have 

been posted in a spreadsheet on EPA’s 

website. 

DATES: September 22, 2021. 

FOR FURTHER INFORMATION CONTACT: 

Questions concerning this action should 

be addressed to Garrett Powers at (202) 

564–2300 or powers.jamesg@epa.gov. 

SUPPLEMENTARY INFORMATION: The 

regulations for each CSAPR trading 

program contain ‘‘assurance provisions’’ 

designed to ensure that the emissions 

reductions required from each state 

covered by the program occur within 

the state. If the total emissions from a 

given state’s affected units exceed the 

state’s assurance level under the 

program, then two allowances must be 

surrendered for each ton of emissions 

exceeding the assurance level (in 

addition to the ordinary obligation to 

surrender one allowance for each ton of 

emissions). In the quarterly emissions 

reports covering the 2020 control 

period, Mississippi and Missouri units 

participating in the CSAPR NOX Ozone 

Season Group 2 Trading Program 

reported emissions that exceed the 

respective states’ assurance levels under 

the program. Mississippi units exceeded 

that state’s assurance level by 260 tons, 

resulting in a requirement for the 

surrender of 520 additional allowances, 

and Missouri units exceeded that state’s 

assurance level by 2,438 tons, resulting
