This notice announces the availability of EPA's revised human health risk assessment for the registration review of chlorpyrifos and opens a public comment period on this document. A preliminary human health risk assessment was completed and released for public comment in July 2011 (76 FR 39399) and is available in the chlorpyrifos registration review docket. Registration review is EPA's periodic review of pesticide registrations to ensure that each pesticide continues to satisfy the statutory standard for registration, that is, the pesticide can perform its intended function without unreasonable adverse effects on human health or the environment. As part of the registration review process, the Agency has completed a comprehensive revised human health risk assessment for all chlorpyrifos uses. A Guide to Commenters document has been placed in the docket along with the revised human health assessment. This document poses questions for the public to comment on. Such comments and input could address, among other things, the Agency's risk assessment methodologies and assumptions, as applied to this revised risk assessment as well as submitting suggestions for mitigating any risks identified in the revised risk assessment. The Agency will consider all comments received during the public comment period and the responses to the questions and any other information that is provided will help in developing a proposed registration review decision on chlorpyrifos. Through this program, EPA is ensuring that each pesticide's registration is based on current scientific and other knowledge, including its effects on human health and the environment.

The Environmental Protection Agency (EPA) is partially approving and partially disapproving the State Implementation Plan (SIP) submittal from Washington, received September 22, 2014, demonstrating that the SIP meets the infrastructure requirements of the Clean Air Act (CAA) for the National Ambient Air Quality Standards (NAAQS) promulgated for ozone on March 12, 2008, and nitrogen dioxide (NO2) on January 22, 2010. The CAA requires that each state, after a new or revised NAAQS is promulgated, review their SIP to ensure that it meets the infrastructure requirements necessary to implement the new or revised NAAQS. Washington certified that the Washington SIP meets the infrastructure requirements of the CAA for the 2008 ozone and 2010 NO2 NAAQS, except for those requirements related to the Prevention of Significant Deterioration (PSD) permitting program currently operated under a Federal Implementation Plan (FIP), certain elements of the regional haze program currently operated under a FIP, and specific requirements related to interstate transport which will be addressed in a separate action. The EPA has determined that the Washington SIP is adequate for purposes of the infrastructure SIP requirements of the CAA with the exceptions noted above. The EPA has determined that the SIP deficiencies related to PSD permitting and regional haze, however, have been adequately addressed by the existing EPA FIPs and, therefore, no further action is required by Washington or the EPA for those elements. The EPA will address the remaining interstate transport requirements in a separate action.
