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 ortho-phthalaldehyde (OPA) (CAS No. 643-79-8) to treat the 
International Space Station internal active thermal control system 
(IATCS) coolant including the United States (U.S.) Laboratory, the 
Japanese Experiment Module, the Columbus and Node with a total volume 
of 829 L with a maximum of 1,974 cm\3\ OPA resin/year to control 
aerobic/microaerophilic water bacteria. The applicant proposes the use 
of a new chemical which has not been registered by EPA. EPA is 
soliciting public comment before making the decision whether or not to 
grant the exemption.

DATES: Comments must be received on or before August 8, 2013.

SUPPLEMENTARY INFORMATION: 

I. General Information

A. Does this action apply to me?

    You may be potentially affected by this action if you are an 
agricultural producer, food manufacturer, or pesticide manufacturer. 
The following list of North American Industrial Classification System 
(NAICS) codes is not intended to be exhaustive, but rather provides a 
guide to help readers determine whether this document applies to them. 
Potentially affected entities may include:
     Crop production (NAICS code 111).
     Animal production (NAICS code 112).
     Food manufacturing (NAICS code 311).
     Pesticide manufacturing (NAICS code 32532).

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 submitting comments, 
remember to:
    i. Identify the document by docket ID number and other identifying 
information (subject heading, Federal Register date and page number).
    ii. Follow directions. The Agency may ask you to respond to 
specific questions or organize comments by referencing a Code of 
Federal Regulations (CFR) part or section number.
    iii. Explain why you agree or disagree; suggest alternatives and 
substitute language for your requested changes.
    iv. Describe any assumptions and provide any technical information 
and/or data that you used.
    v. If you estimate potential costs or burdens, explain how you 
arrived at your estimate in sufficient detail to allow for it to be 
reproduced.
    vi. Provide specific examples to illustrate your concerns and 
suggest alternatives.
    vii. Explain your views as clearly as possible, avoiding the use of 
profanity or personal threats.
    viii. Make sure to submit your comments by the comment period 
deadline identified.
    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 OPA in 
the International Space Station IATCS coolant to control aerobic/
microaerophilic water bacteria. Information in accordance with 40 CFR 
part 166 was submitted as part of this request.
    As part of this request, the applicant asserts that OPA is the most 
effective biocide which 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. Non-use of OPA in the requested manner would leave 
NASA's International Space Station without an adequate long-term 
solution for controlling the micro-organisms in the coolant systems.
    The Applicant proposes to make no more than 1 application of OPA/
loop in the International Space Station IATCS coolant including the 
U.S. Laboratory, the Japanese Experiment Module, the Columbus and Node 
with a total volume not to exceed 829 L with a maximum of 1,974 cm\3\ 
OPA resin.
    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 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.
