CA SB426

State Water Resources Control Board must establish financial capability assessment guidelines for municipal separate storm sewer system permittees by July 1, 2022, considering costs to local jurisdictions including previously incurred costs.

Guidelines must be adequate and consistent when evaluating implementation costs, and the state board must document sources used to estimate local costs and overall stormwater management costs.

State board and regional boards shall continue using available regulatory tools and collaborative approaches with permittees to implement permit requirements while considering implementation costs.

Guidelines development must consider federal Environmental Protection Agency policies on financial capability assessment and affordability criteria for small drinking water systems.
