HI HB2145

Excludes clean, naturally occurring beach sand from the definition of "water pollutant" under Hawaii's water pollution control regulations if sourced locally from beaches, stream mouths, or channels.

Allows locally sourced beach sand to be used for beach erosion mitigation, sediment management, beach restoration, erosion control, or dune restoration on adjoining beaches or littoral cells without requiring water quality permits.

Addresses the loss of Hawaii's beaches, with studies showing 70% of beaches on Kauai, Oahu, and Maui are eroding and more than 13 miles lost over the past century.

Clarifies that the exemption does not circumvent federal Clean Water Act provisions but rather recognizes that locally sourced beach sand is a naturally occurring material, not a pollutant.

Takes effect July 1, 2050.
