A National Pollutant Discharge Elimination System (NPDES) permit is required of the City and County of Honolulu (City) due to the discharge of storm water from City drainage systems into receiving State water bodies. This requirement is regulated by the Clean Water Act (CWA) (33 United States Code [U.S.C.] 125 1 et. seq.; the “Act”); Hawaii Revised Statutes (HRS), Chapter 342D; and Hawaii Administrative Rules, Department of Health (DOH), State of Hawaii, Chapters 11-54 and 11-55, as amended. The permit includes six (6) program components:

• Public Education and Outreach
• Illicit Discharge Detection and Elimination
• Construction Site Runoff Control
• Post-Construction Storm Water Management
• Pollution Prevention and Good Housekeeping
• Industrial and Commercial Activities Discharge Management

AECOM has been helping the City to develop a comprehensive storm water management program to address the requirements of the NPDE permit and to reduce, to the Maximum Extent Practicable (MEP), the discharge of pollutants to and from the City’s Municipal Separate Storm Sewer System (MS4) to protect water quality and to satisfy the appropriate water quality requirements of the Clean Water Act.
