Make sure to submit your comments by the comment period deadline identified. sroberts on DSK5SPTVN1PROD with NOTICES D. What action is the Agency taking? Volatilization of a pesticide can be characterized as the physical movement of the vapor phase of a pesticide through the air after an application has occurred from the target site to any nonor off-target site. This does not include pesticide movements by spray drift, erosion, migration, or windblown soil particles after application. Volatilization is dependent on a number of physical and chemical properties, weather conditions, and other factors. Once offtarget, pesticide volatilization can result in inhalation exposure to people, such as bystanders. EPA has developed a guidance document describing EPA’s approach in developing a volatilization screening methodology for human health. The ‘‘Human Health Bystander Screening Level Analysis: Volatilization of Conventional Pesticides’’ document (and its appendices) describes the development of the screening tool, the guiding principles behind the screening tool, the various inputs utilized in the screening tool, and the results of the screening analysis that EPA has recently completed using this methodology. These documents are available in the docket for this action using the docket ID number EPA–HQ–OPP–2014–0219 (Refs. 1, 2, 3, 4, and 5). These policies will promote consistency within EPA, as well as with other Federal agencies and international regulatory partners that consider volatilization for pesticides. II. Consideration of Volatilization in Human Health Risk Assessment Over many years, EPA has been actively engaged in evaluating possible exposures associated with air borne, offtarget movement of pesticides. EPA has worked to develop and refine its methodologies for assessing bystander inhalation exposures resulting from VerDate Mar<15>2010 17:43 Mar 25, 2014 Jkt 232001 volatilization of fumigants as well as to spray drift from the application of conventional pesticides in agricultural settings. Recently, EPA published a notice for comment in the Federal Register of January 29, 2014 (79 FR 4691) (FRL–9903–12) two draft guidance documents describing how EPA plans to evaluate off-site spray drift for ecological and human health risk assessments. These documents are available at regulations.gov using the docket ID number EPA–HQ–OPP–2013– 0676. To account for volatilization from non-fumigant uses, EPA has been adapting the approaches developed for conducting risk assessments for the fumigants in assessing potential bystander inhalation risk. Notable milestones in this effort include the 2009 FIFRA Scientific Advisory Panel (SAP) review of issues related to volatilization of conventional pesticides (Ref. 6) and the 2013 chlorpyrifos preliminary volatility assessment (Ref. 7). These adaptations have resulted in a Volatilization Screening Tool that provides a consistent and health protective framework to assess the potential inhalation bystander risks resulting from volatilization of conventional pesticides. A Volatilization Screening Tool Guidance Document (Ref. 2) was produced to support the screening tool. To estimate potential bystander inhalation risks, the screening tool uses: • A number of physical and chemical properties to predict flux (i.e., the rate at which a chemical volatilizes off of a treated field). • The AERSCREEN model (Ref. 8) to estimate air concentrations at different distances from a treated field. • Chemical-specific human health toxicological data. Four of the draft documents (Refs. 1, 2, 3, and 4) provide details on the volatilization screening methodology including the development of the screening tool, the guiding principles behind the screening tool, and the various inputs used in the screening tool. To demonstrate the application of this methodology, two documents (Refs. 1 and 5) present the results of the screening analysis that EPA completed using this methodology which examined all of the conventional pesticides being evaluated in the Registration Review process. It is important to note that ‘‘failing’’ the screening analysis does not necessarily mean that the pesticide poses a risk of concern due to volatilization. Rather, due to the purposely conservative nature of the screening analysis, failing PO 00000 Frm 00039 Fmt 4703 Sfmt 4703 the screen is merely a trigger for the Agency to further investigate the question of exposure from volatilization of the pesticide.

SUPPLEMENTARY INFORMATION: 

I. General Information

A. What is the Agency's authority for taking this action?

    Pesticides are regulated under both the Federal Insecticide, 
Fungicide, and Rodenticide Act (FIFRA), 7 U.S.C. 136 et. seq., and 
section 408 of the Federal Food, Drug, and Cosmetic Act (FFDCA), 21 
U.S.C. 346a.

B. Does this action apply to me?

    You may be potentially affected by this action if you are a 
producer of pesticide products (NAICS code 32532), importers of such 
products, or any person or company who seeks to obtain a tolerance for 
such a pesticide. The North American Industrial Classification System 
(NAICS) code 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.

C. What should I consider as I prepare my comments for EPA?

    1. Submitting CBI. Do not submit this information to EPA through 
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.

[[Page 16792]]

    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.

D. What action is the Agency taking?

    Volatilization of a pesticide can be characterized as the physical 
movement of the vapor phase of a pesticide through the air after an 
application has occurred from the target site to any non- or off-target 
site. This does not include pesticide movements by spray drift, 
erosion, migration, or windblown soil particles after application. 
Volatilization is dependent on a number of physical and chemical 
properties, weather conditions, and other factors. Once off-target, 
pesticide volatilization can result in inhalation exposure to people, 
such as bystanders.
    EPA has developed a guidance document describing EPA's approach in 
developing a volatilization screening methodology for human health. The 
``Human Health Bystander Screening Level Analysis: Volatilization of 
Conventional Pesticides'' document (and its appendices) describes the 
development of the screening tool, the guiding principles behind the 
screening tool, the various inputs utilized in the screening tool, and 
the results of the screening analysis that EPA has recently completed 
using this methodology.
    These documents are available in the docket for this action using 
the docket ID number EPA-HQ-OPP-2014-0219 (Refs. 1, 2, 3, 4, and 5). 
These policies will promote consistency within EPA, as well as with 
other Federal agencies and international regulatory partners that 
consider volatilization for pesticides.

II. Consideration of Volatilization in Human Health Risk Assessment

    Over many years, EPA has been actively engaged in evaluating 
possible exposures associated with air borne, off-target movement of 
pesticides. EPA has worked to develop and refine its methodologies for 
assessing bystander inhalation exposures resulting from volatilization 
of fumigants as well as to spray drift from the application of 
conventional pesticides in agricultural settings. Recently, EPA 
published a notice for comment in the Federal Register of January 29, 
2014 (79 FR 4691) (FRL-9903-12) two draft guidance documents describing 
how EPA plans to evaluate off-site spray drift for ecological and human 
health risk assessments. These documents are available at 
regulations.gov using the docket ID number EPA-HQ-OPP-2013-0676.
    To account for volatilization from non-fumigant uses, EPA has been 
adapting the approaches developed for conducting risk assessments for 
the fumigants in assessing potential bystander inhalation risk. Notable 
milestones in this effort include the 2009 FIFRA Scientific Advisory 
Panel (SAP) review of issues related to volatilization of conventional 
pesticides (Ref. 6) and the 2013 chlorpyrifos preliminary volatility 
assessment (Ref. 7).
    These adaptations have resulted in a Volatilization Screening Tool 
that provides a consistent and health protective framework to assess 
the potential inhalation bystander risks resulting from volatilization 
of conventional pesticides. A Volatilization Screening Tool Guidance 
Document (Ref. 2) was produced to support the screening tool. To 
estimate potential bystander inhalation risks, the screening tool uses:
     A number of physical and chemical properties to predict 
flux (i.e., the rate at which a chemical volatilizes off of a treated 
field).
     The AERSCREEN model (Ref. 8) to estimate air 
concentrations at different distances from a treated field.
     Chemical-specific human health toxicological data.
    Four of the draft documents (Refs. 1, 2, 3, and 4) provide details 
on the volatilization screening methodology including the development 
of the screening tool, the guiding principles behind the screening 
tool, and the various inputs used in the screening tool. To demonstrate 
the application of this methodology, two documents (Refs. 1 and 5) 
present the results of the screening analysis that EPA completed using 
this methodology which examined all of the conventional pesticides 
being evaluated in the Registration Review process. It is important to 
note that ``failing'' the screening analysis does not necessarily mean 
that the pesticide poses a risk of concern due to volatilization. 
Rather, due to the purposely conservative nature of the screening 
analysis, failing the screen is merely a trigger for the Agency to 
further investigate the question of exposure from volatilization of the 
pesticide.
