Triennial Review

Nevada Triennial Review of Surface Water Quality Standards

The Nevada Division of Environmental Protection (NDEP) holds public meetings every three years to review and update the state's surface water quality standards. This process, mandated by the Federal Water Pollution Control Act and 40 CFR 131.20, involves a formal public comment period where citizens can provide input. After considering public feedback, the NDEP Bureau of Water Quality Planning (BWQP) and the State Environmental Commission work together to adopt selected standards, ensuring they align with state and federal laws, public interest, and the best available science.

Note: This review does not apply to drinking water or groundwater standards.
