Triennial Review
Public Process to Solicit Comments on Nevada’s Water Quality Standards
Section 303(c) of the federal Clean Water Act requires that states review existing water quality standards (WQS) at least once every three years. The Nevada Division of Environmental Protection (NDEP) and the State Environmental Commission meet this requirement through the adoption of water quality standards into the Nevada Administrative Code (NAC) on a regular basis. Additionally, about once every three years, the NDEP Bureau of Water Quality Planning (BWQP) opens a Triennial Review public comment period and holds public workshops to solicit input on WQS issues and concerns that NDEP should evaluate during the next several year timeframe.
Letters submitted during the Triennial Review comment period with NDEP responses, and the public workshop meeting notes are provided below. Recordings of the workshops are available on request.
