2. Information Collection Request (ICR) Agencies requesting submission of information by the public must demonstrate the “practical utility,” or benefit, of the information and enumerate the public “burden,” or cost, of the collection – The Tier 1 data and OSRI are needed and will be used to provide information that will allow EPA to determine “that a chemical does, or is not likely to, have the potential to interact with the endocrine system.”

3. ICR Practical Utility: Means “the actual not merely theoretical or potential, usefulness of information to or for an agency, taking into account its accuracy, validity, adequacy, and reliability, and the agency’s ability to process the information it collects in a useful and timely fashion…” Burden: Means “the total time, effort or financial resources expended by persons to generate, maintain, retain, or disclose or provide information to or for a Federal agency, including: Developing, acquiring, installing, and utilizing technology and systems for the purpose of collecting, validating, and verifying information; Searching data sources.”

4. EDSP Information Collection Request OMB Action: Approved with Change “Terms of Clearance” “…under the principles of the PRA, EPA should promote and encourage test order recipients to submit Other Scientifically Relevant Information (OSRI) in lieu of performing all or some of the Tier I assays, and EPA should accept OSRI as sufficient to satisfy the test orders to the greatest extent possible.” “…to further validate EPA’s burden estimates, OMB requests that EPA provide a report re-estimating the burden of this information collection based on responses to the Tier I test orders, including the use of cost-sharing and data compensation, the submission and acceptance of existing data and OSRI, and description of any instances in which submission of OSRI was deemed insufficient to satisfy the testing order.” “… in order to ensure that EPA has maximized the practical utility of the Tier I assays…, EPA should ensure sufficient opportunity prior to submission of any revision to this collection for public comment and peer review of the EPA tools to be developed to guide the agency decisions on whether a chemical must proceed to Tier II, including the Weight of Evidence Approach and Standard Evaluation Procedures.”

5. Status of List 1 Activity All responses to List 1 Test Orders have been submitted EPA has made OSRI decisions on 15 chemicals Of the 58 List 1 pesticide active ingredients: 30 are being “supported” in consortia 143 members in total, 4-5 members per consortia on average, range of 2-17 members 21 are being “supported” by a single company 7 are not being “supported” 20 registrations have been voluntarily cancelled Of the 9 List 1 pesticide inert ingredients: 2 inerts are being “supported” in consortia One consortium of 2 companies, the other of 7 (so far) Data Submission OSRI submitted for 46 actives New Data generated for 5 actives and 2 inerts 769 Test Orders sent out: 173 responses to “support,” 596 “other” responses (e.g., formulators exemption, opt-out of pesticide market, not subject to test order, response outstanding) There will be only one final response for each “supported” chemical
