CA AB2364

State Water Resources Control Board must establish financial capability assessment guidelines for municipal stormwater system permittees by July 1, 2021, that adequately account for local jurisdiction compliance costs.

State and regional water boards shall continue using available regulatory tools to collaborate with permittees on implementing permit requirements while considering implementation costs.

Guidelines must document sources used to estimate local costs and overall stormwater management costs, and shall consider EPA policies on financial capability assessment and affordability for small water systems.

Legislation aims to help local governments lacking dedicated revenue sources or having insufficient revenue to meet stormwater compliance costs without weakening environmental protections.

State and regional boards may adjust compliance timeframes and develop alternative compliance pathways for disadvantaged communities while maintaining Clean Water Act compliance.
