Hawaii State Law (Section 269E-7, found on page 14 of the Hawaii One Call Center handbook) requires that excavators provide notice at least five (5) working days, but not more than twenty-eight (28) calendar days, prior to beginning planned excavation.
Working days are based on normal business hours, from 7am to 5pm, and do not include the holidays listed at the bottom of this page. Because the Hawaii One Call Center is available every day, the 5 business day notification period will begin at the start of the next business day for notices called in after 5pm or on holidays.
