It is important to note that EPA’s policy is that public comments, whether submitted electronically or in paper, will be made available for public viewing online at www.regulations.gov without change, unless the comment contains copyrighted material, CBI, or other information whose disclosure is restricted by statute. Information claimed as CBI and other information whose disclosure is restricted by statute is not included in the official public docket or in the electronic public docket. EPA’s policy is that copyrighted material, including copyrighted material contained in a public comment, will not be placed in EPA’s electronic public docket but will be available only in printed, paper form in the official public docket. Although not all docket materials may be available electronically, you may still access any of the publicly available docket materials through the EPA Docket Center. B. How and to whom do I submit comments? You may submit comments as provided in the ADDRESSES section. Please ensure that your comments are submitted within the specified comment period. Comments received after the close of the comment period will be marked ‘‘late.’’ EPA is not required to consider these late comments. If you submit an electronic comment, EPA recommends that you include your name, mailing address, and an email address or other contact information in the body of your comment and with any disk or CD–ROM you submit. This ensures that you can be identified as the submitter of the comment and allows EPA to contact you in case EPA cannot read your comment due to technical difficulties or needs further information on the substance of your comment. Any identifying or contact information provided in the body of a comment will be included as part of the comment that is placed in the official public docket, and made available in EPA’s electronic public docket. If EPA cannot read your comment due to technical difficulties and cannot contact you for clarification, EPA may not be able to consider your comment.

The electronic public docket system is an ‘‘anonymous access’’ system, which means EPA will not know your identity, email address, or other contact information unless you provide it in the body of your comment. In contrast to EPA’s electronic public docket, EPA’s electronic mail (email) system is not an ‘‘anonymous access’’ system. If you send an email comment directly to the Docket without going through www.regulations.gov, your email address is automatically captured and included as part of the comment that is placed in the official public docket, and made available in EPA’s electronic public docket.

White Paper on Development of Community Water System Drinking 
Water Intake Percent Cropped Area Adjustment Factors for Use in 
Drinking Water Exposure Assessments; Notice of Availability

AGENCY: Environmental Protection Agency (EPA).

ACTION: Notice.

-----------------------------------------------------------------------

SUMMARY: The Environmental Protection Agency uses computer modeling to 
estimate human exposure to pesticides in drinking water. An input 
parameter for these exposure models is the percentage of a water 
supply's watershed area to which pesticides may be applied, a metric 
which EPA refers to as the ``percent cropped area'' (PCA). Recently, 
EPA has developed delineations of watersheds for surface water intakes 
of community water systems throughout the continental United States and 
has used this dataset to develop a corresponding dataset of watershed-
specific PCAs. Development of this Community-Water System--Drinking 
Water Intake dataset is described in a draft white paper, which has 
been updated based on peer review comments. EPA is making this updated 
version available for public review and comment.

    The Agency's authority is FIFRA (7 U.S.C. 136-136y).
