Scientific Information Request on Vitamin D and Calcium, 42952-42954 [2013-17177]

Download as PDF 42952 Federal Register / Vol. 78, No. 138 / Thursday, July 18, 2013 / Notices form as a common form, meaning HHS will only request approval for its own use of the form rather than aggregating the burden estimate across all Federal Agencies as was done for previous actions on this OMB control number. Comments submitted during the first public review of this ICR will be provided to OMB. OMB will accept further comments from the public on this ICR during the review and approval period. DATES: Comments on the ICR must be received on or before August 19, 2013. ADDRESSES: Submit your comments to OIRA_submission@omb.eop.gov or via facsimile to (202) 395–5806. FOR FURTHER INFORMATION CONTACT: Information Collection Clearance staff, Information.CollectionClearance@hhs. gov or (202) 690–6162. SUPPLEMENTARY INFORMATION: When submitting comments or requesting information, please include the OMB control number 4040–0004 and document identifier HHS–EGOV– 16500–30D for reference. Information Collection Request Title: SF–424 Discretionary. OMB No.: 4040–0004. Abstract: The SF–424 Application for Federal Assistance is a common form used by all Federal grant-making agencies for applicants to apply for Federal financial assistance. Need and Proposed Use of the Information: The SF–424 Application for Federal Assistance is used by the public to apply for Federal financial assistance in the form of grants. These forms are submitted to the Federal grant-making agencies for evaluation and review. Likely Respondents: Organizations and institutions seeking grants. Burden Statement: Burden in this context means the time expended by persons to generate, maintain, retain, disclose or provide the information requested. This includes the time needed to review instructions, to develop, acquire, install and utilize technology and systems for the purpose of collecting, validating and verifying information, processing and maintaining information, and disclosing and providing information, to train personnel and to be able to respond to a collection of information, to search data sources, to complete and review the collection of information, and to transmit or otherwise disclose the information. The total annual burden hours estimated for this ICR are summarized in the table below. HHS estimates that the SF–424 Application for Federal Assistance will take 1 hour to complete. We expect that 14,747 respondents will use this form. Once OMB approves the use of this common form, federal agencies may request OMB approval to use this common form without having to publish notices and request public comments for 60 and 30 days. Each agency must account for the burden associated with their use of the common form.
