EPA Responses to Certain State Designation Recommendations for the 2010 Sulfur Dioxide National Ambient Air Quality Standard: Notice of Availability and Public Comment Period
Notice is hereby given that the Environmental Protection Agency (EPA) has posted on its Internet Web site responses to certain state designation recommendations for the 2010 Sulfur Dioxide (SO2) National Ambient Air Quality Standard (NAAQS). The EPA invites the public to review and provide input on its responses during the comment period specified in the DATES section. The EPA sent its responses directly to the states on or about February 16, 2016. The EPA intends to make final the designation determinations for the areas of the country addressed by these responses no later than July 2, 2016.
Notification of a Public Meeting of the Chartered Science Advisory Board
The Environmental Protection Agency (EPA) Science Advisory Board (SAB) Staff Office announces a public meeting of the chartered SAB to: (1) Conduct a quality review of a draft SAB report on an accounting framework for biogenic carbon dioxide emissions; (2) discuss information provided by the EPA on planned actions in the Fall 2015 semi-annual regulatory agenda and their supporting science; and (3) receive briefings from the EPA Office of Research and Development and the Office of the Science Advisor.
Request for Nominations for Peer Reviewers for EPA's Biologically Based Dose-Response (BBDR) Model for Perchlorate in Drinking Water
The U.S. Environmental Protection Agency (EPA) invites the public to nominate scientific experts to be considered as peer reviewers for the contractor-managed, external peer review of the draft Biologically Based Dose-Response model for perchlorate in drinking water and the draft model support document. The draft model predicts changes in thyroid hormones in sensitive life stages exposed to different dietary iodide and perchlorate levels. EPA has been working with scientists at the Food and Drug Administration to develop the model recommended by EPA's Science Advisory Board for the derivation of a maximum contaminant level goal for perchlorate in drinking water. The model integrates previous perchlorate and iodine models for thyroid hormones in formula-fed and nursing infants, as well as lactating women. The model predicts the effects of perchlorate on serum thyroid hormone concentrations in infants exposed via ingestion of formula mixed with contaminated drinking water or breast milk. EPA anticipates releasing the draft model and draft model support document for peer review and public comment in the near future (the exact date to be determined).
Request for Public Comment on the Draft EPA-USGS Technical Report: Protecting Aquatic Life From Effects of Hydrologic Alteration
The Environmental Protection Agency (EPA) and the United States Geological Survey are releasing a draft technical report: Protecting Aquatic Life from Effects of Hydrologic Alteration, for a 60-day public comment period. This report was developed because hydrologic alteration can be a contributor of impairment for water bodies that are designated to support aquatic life. Stresses on aquatic life associated with hydrologic alteration may be further exacerbated through climate change. Recent climate trends have included the change in frequency and duration of extreme weather events, such as droughts and floods, which can have an impact on flow and affect aquatic life. The report is a nonprescriptive framework with information to help states, tribes, territories, water resource managers, and other stakeholders responsible for the maintenance of hydrologic flow regime to quantify flow targets for the preservation of aquatic life and habitat. This report also provides information on the relationship between hydrologic condition and water quality and gives examples of what some states and authorized tribes have done to address flow concerns using the Clean Water Act. The framework can also be used to translate narrative criteria and develop flow targets to protect aquatic life and habitat.
Environmental Laboratory Advisory Board (ELAB) Membership
The U.S. Environmental Protection Agency's (EPA) invites nominations from a diverse range of qualified candidates to be considered for appointment to its Environmental Laboratory Advisory Board (ELAB). The ELAB is a multi-stakeholder federal advisory committee that provides independent advice and recommendations to the EPA Administrator, Science Advisor, and Forum on Environmental Measurements (FEM) about cross-cutting issues related to enhancing EPA's measurement programs, and facilitating the operation and expansion of national environmental accreditation. This notice solicits nominations to fill eight-nine (8-9) new vacancies. To maintain diverse representation, nominees will be selected from the following stakeholder work force sectors:
Approval and Promulgation of Air Quality Implementation Plans; Wyoming; Revisions to Wyoming Air Quality Standards and Regulations; Chapter 6, Permitting Requirements, Section 13, Nonattainment New Source Review Permit Requirements, and Section 14, Incorporation by Reference
The Environmental Protection Agency (EPA) is proposing to approve State Implementation Plan (SIP) revisions submitted by the State of Wyoming on November 6, 2015. This submittal revises the Wyoming Air Quality Standards and Regulations (WAQSR) that pertain to the issuance of Wyoming air quality permits for major sources in nonattainment areas. This action is being taken under section 110 of the Clean Air Act (CAA).
