The New York State Department of Environmental Conservation (NYSDEC) Division of Water (DOW) is releasing three draft Technical and Operational Guidance Series (TOGS) documents for public review and comment. The draft TOGS documents being released include:

· Addendum to "TOGS 1.1.1: Ambient Water Quality Standards and Guidance Values and Groundwater Effluent Limitations." The draft TOGS addendum establishes water quality guidance values (GVs) for Perfluorooctanoic acid (PFOA), Perfluorooctanesulfonic acid (PFOS), and 1,4-Dioxane.

· A revision of "TOGS 1.3.7: Analytical Detectability and Quantitation Guidelines for Selected Environmental Parameters." The revision establishes how NYSDEC selects analytical test methods for water quality monitoring and determines reporting limits for those methods. There are limited methods approved by State or Federal oversight bodies for PFOA, PFOS, and 1,4-Dioxane, therefore this TOGS provides critical guidance on how to select analytical test methods for monitoring of these compounds.

· A new "TOGS 1.3.13: Permitting Strategy for Implementing Guidance Values for PFOA, PFOS, and 1,4-Dioxane." The new TOGS establish how the GVs for PFOA, PFOS, and 1,4-Dioxane will be applied to SPDES permits. This guidance will take effect when the GVs are issued.

New York State Department of Health (DOH) adopted Maximum Contaminant Levels (MCLs) for PFOA, PFOS, and 1,4-Dioxane (1,4-D) in August of 2020. While the DOH MCLs provide protection for finished drinking water, NYSDEC's proposed GVs and supporting TOGS will provide timely and parallel protection of ambient waters, including those used as drinking water sources. The proposed GVs for PFOS and 1,4-D also provide protection for aquatic life and the associated fishing best use.
