not part of the prior review, and that 

have been published or accepted for 

publication in a peer-reviewed journal. 

The Agency is interested in obtaining 

newly available information, 

particularly concerning toxicological 

studies of effects of controlled exposure 

to O3 in laboratory animals, humans, 

and in vitro systems; epidemiologic 

(observational) studies of health effects 

associated with ambient O3 exposures in 

human populations; studies examining 

populations and life stages that may be 

at increased risk of O3-related health 

effects.. For studies examining effects on 

welfare or the environment, studies that 

address or provide new information on 

terrestrial biota are of particular interest, 

including effects of O3 on vegetation; 

communities and populations of plants 

and associated biota, as well as 

exposure-response relationships 

between O3 in ambient air and specific 

welfare effects. The EPA also seeks 

recent information in other areas of O3

research such as atmospheric chemistry 

and physics, sources and emissions, 

analytical methodology, transport and 

transformation in the environment, and 

ambient concentrations. 

The Agency also seeks information 

regarding the design and scope of the 

review of the air quality criteria to 

ensure that it addresses key policyrelevant issues and considers the new 

science that is relevant to informing our 

understanding of these issues. The 

Agency seeks new scientific information 

that may address key uncertainties 

identified in the last O3 NAAQS review, 

which are provided in section 3.6 of the 

2020 Policy Assessment (EPA–452/R– 

20–001, May 2020).3 The Agency also 

seeks new scientific information or data 

that may address scientific and 

technical issues raised in two more 

recent letters from CASAC: one dated 

November 22, 2022 (EPA–CASAC–23– 

001) 4 and the other dated June 9, 2023 

(EPA–CASAC–23–002).5 Other 

opportunities for submission of new 

peer-reviewed, published (or in-press) 

papers will be possible as part of public 

comment on the draft ISA that will be 

reviewed by the CASAC.

Ortho-Phthalaldehyde; Receipt of 

Application for Emergency Exemption, 

Solicitation of Public Comment 

AGENCY: Environmental Protection 

Agency (EPA). 

ACTION: Notice. 

SUMMARY: EPA has received a specific 

exemption request from the National 

Aeronautics and Space Administration 

(NASA) to use the pesticide orthophthalaldehyde (OPA, CAS No. 643–79– 

8) to treat the coolant fluid of the 

internal active thermal control system of 

the International Space Station to 

control aerobic/microaerophilic bacteria 

in the aqueous coolant. The applicant 

proposes the use of a new chemical 

which has not been registered by EPA. 

Therefore, in accordance with the Code 

of Federal Regulations, EPA is soliciting 

public comment before making the

decision whether to grant the 

exemption. 

DATES: Comments must be received on 

or before September 11, 2023. 

ADDRESSES: Submit your comments, 

identified by docket identification (ID) 

number EPA–HQ–OPP–2023–0404,

SUPPLEMENTARY INFORMATION: 

I. General Information 

A. Does this action apply to me? 

You may be potentially affected by 

this action if you are a pesticide 

manufacturer, North American 

Industrial Classification System 

(NAICS) (Code 32532) or involved with 

the International Space Station. This 

listing is not intended to be exhaustive, 

but rather provides a guide to help 

readers determine whether this 

document applies to them. Other types 

of entities not listed could also be 

affected. 

B. What should I consider as I prepare 

my comments for EPA? 

1. Submitting CBI. Do not submit this 

information to EPA through 

www.regulations.gov or email. Clearly 

mark the part or all of the information 

that you claim to be CBI. For CBI 

information in a disk or CD–ROM that 

you mail to EPA, mark the outside of the 

disk or CD–ROM as CBI and then 

identify electronically within the disk or 

CD–ROM the specific information that 

is claimed as CBI. In addition to one 

complete version of the comment that 

includes information claimed as CBI, a 

copy of the comment that does not 

contain the information claimed as CBI 

must be submitted for inclusion in the 

public docket. Information so marked 

will not be disclosed except in 

accordance with procedures set forth in 

40 CFR part 2. 

2. Tips for preparing your comments. 

When preparing and submitting your 

comments, see the commenting tips at 

https://www.epa.gov/dockets/ 

commenting-epa-dockets. 

3. Environmental justice. EPA seeks to 

achieve environmental justice, the fair 

treatment and meaningful involvement 

of any group, including minority and/or 

low-income populations, in the 

development, implementation, and 

enforcement of environmental laws, 

regulations, and policies. To help 

address potential environmental justice 

issues, the Agency seeks information on 

any groups or segments of the 

population who, as a result of their 

location, cultural practices, or other 

factors, may have atypical or 

disproportionately high and adverse 

human health impacts or environmental 

effects from exposure to the pesticide(s) 

discussed in this document, compared 

to the general population. 

II. What action is the Agency taking? 

Under section 18 of the Federal 

Insecticide, Fungicide, and Rodenticide 

Act (FIFRA) (7 U.S.C. 136p), at the 

discretion of the EPA Administrator, a 

Federal or State agency may be 

exempted from any provision of FIFRA 

if the EPA Administrator determines 

that emergency conditions exist which 

require the exemption. NASA has 

requested the EPA Administrator to 

issue a specific exemption for the use of 

ortho-phthalaldehyde (OPA) in the 

coolant of the internal active thermal 

control system (IATCS) of the 

International Space Station (ISS) to 

control aerobic/microaerophilic bacteria 

in the aqueous coolant. Information in 

accordance with 40 CFR part 166 was 

submitted as part of this request. 

As part of this request, the applicant 

asserted that it has considered the 

registered biocide alternatives and has 

concluded that OPA is the most 

effective biocide that meets the requisite 

criteria including: The need for safe, 

non-intrusive implementation and 

operation in a functioning system; the 

ability to control existing planktonic 

and biofilm-residing micro-organisms; a 

negligible impact on system wetted 

materials of construction; and a 

negligible reactivity with existing 

coolant additives. The ISS would not 

have an adequate long-term solution for 

controlling the micro-organisms in the 

IATCS coolant without the use of OPA. 

The OPA is incorporated into a porous 

resin material contained in a stainlesssteel canister. The canister containing 

the OPA-incorporated resin is inserted 

into a coolant system loop, using 

flexible hose and quick disconnects and 

is placed in line for 8 hours to deliver 

the OPA into the fluid. As the coolant 

fluid flows through the cannister, the 

OPA elutes from the resin material into 

the coolant fluid. The total volume of 

the circulatory loops of the IATCS is 

829 liters. The maximum concentration 

would be 350 milligrams (mg) of OPA 

per liter of coolant fluid. A total of 

290,150 mg would be needed for the 

entire system. The OPA is incorporated 

into the resin at 210 mg OPA per cm3

resin, resulting in a potential total use 

of 1,382 cm3 of the OPA-containing 

resin. The level of OPA in the coolant 

is monitored periodically, and because 

OPA degrades over time, the 

concentration decreases to a level that is 

no longer effective in about 1 to 2 years. 

At this point, replenishment with new 

OPA-containing canisters is required. 

EPA has authorized similar emergency 

exemptions for this use since 2011. 

With the decision to extend the mission 

of the ISS to 2030, the need for this use 

is expected to continue for the duration 

of the program. 

This notice does not constitute a 

decision by EPA on the application 

itself. The regulations governing FIFRA 

section 18 require publication of a 

notice of receipt of an application for a 

specific exemption proposing the use of 

a new chemical (i.e., an active 

ingredient) which has not been 

registered by EPA. 

The notice provides an opportunity 

for public comment on the application. 

The Agency will review and consider all 

comments received during the comment 

period in determining whether to issue 

the specific exemption requested by the 

NASA.
