Water Quality Data Submissions for Registration Review
The Office of Pesticide Programs (OPP), working with the Office of Water, EPA regions, and state partners, developed the "OPP Standard Operating Procedure: Inclusion of Water Quality & Impaired Water Body Data in OPP's Registration Review Risk Assessment & Management Process". The SOP is intended to encourage submission and use of water quality data during registration review.
To ensure that such data can be used quantitatively or qualitatively in pesticide risk assessments, data should conform as much as possible to the quality standards in Appendix A of the SOP. Voluntary submission of these data to OPP for pesticide cases beginning the registration review process will insure that Clean Water Act Section 303(d) impaired waterbody listing data, and other relevant information for these and other water bodies, can be obtained and considered during the registration review process.
Data may be submitted in advance of opening a pesticide case docket or during the public comment period on the initial docket. While data may be submitted later, EPA's ability to adequately consider late-submitted data will be limited. See the current schedule for opening dockets.
