Purpose of the meeting
DEQ will host a webinar to provide updates to the water quality assessment guidance manual for the 2024 Integrated Report cycle. The draft 2024 Water Quality Assessment Guidance Manual will be released for public comment on March 22, 2023. A list of the updates is provided in Part II of the manual. Virginia’s draft 2024 Water Quality Assessment Guidance Manual contains the assessment procedures and methods to be used for the development of Virginia’s 2024 §305(b)/ §303(d) Integrated (i.e. combined Water Quality Assessment and Impaired Waters) Report. The assessment guidance seeks to address all key elements of the U.S. Environmental Protection Agency (EPA) 2006 Assessment Guidance and subsequent updates current to January 2023, in addition to the assessment methodology for Chesapeake Bay Water Quality Standards established by EPA and adopted by Virginia (Ambient Water Quality Criteria for Dissolved Oxygen, Water Clarity, and Chlorophyll a for the Chesapeake Bay and Its Tidal Tributaries). By the release date, a copy of the draft 2024 Water Quality Assessment Guidance Manual will be available for download from the DEQ Water Quality Assessment webpage at: WQA Guidance Manual | Virginia DEQ. Section 62.1-44.19:5 C of the Code of Virginia requires DEQ to develop and publish the procedures used for defining and determining impaired waters and provide for public comment on the procedures. The public is invited to submit written comments from March 22, 2023 through April 21, 2023. Comments should include the name, address, telephone number, and, if applicable, the e-mail address of each person and/or organization submitting comments. Comments and related correspondence should be addressed to Amanda Shaver (see contact information below). Responses to comments received will be made collectively, via a response document. The response document will be posted on the assessment webpage along with the final guidance manual.
