MODERATE
This bill updates Hawaii's water shortage declaration process to apply statewide, including areas outside designated water management zones. It sets a 90-day maximum duration for water shortage declarations, limits usage restrictions to 20% of last reported monthly usage, and requires the Commission on Water Resource Management to notify all permittees and maintain a notification list. The changes aim to improve transparency and ensure consistent planning during drought conditions across all islands.

TIMELINE

Act effective date set to July 1, 2040.

DEFINITION
