NPDES PESTICIDES PERMIT UPDATE
As of November 1, 2011, point source discharges from the applications of pesticides to waters of the state require National Pollutant Discharge Elimination System (NPDES) Permits, as required by the Clean Water Act. These discharges include applications of pesticides to, over, or near waters of the state. The Hawaii Department of Health (DOH), Clean Water Branch (CWB) is responsible for implementation of the NPDES pesticides permit program in the State of Hawaii.
Currently, applications to, over, or near waters of the state without a NPDES permit would be in violation of the Clean Water Act. However, prior to issuance of any NPDES permit for pesticide discharge, CWB must make revisions to the Hawaii Administrative Rules (HAR), Chapter 11-54 (Water Quality Standards) and 11-55 (Water Pollution Control) and the Water Quality Standard. Please contact the Clean Water Branch at (808) 586-4309 if you have more specific questions on Hawaii's NPDES permit for pesticide discharges. The CWB is currently revising HAR, Chapters 11-54 and 11-55, following the DOH Administrative Rulemaking Process.
