Haley & Aldrich professionals deliver stormwater management program for the County of Maui

Summary

• After becoming regulated following the 2010 census, the County of Maui needed help understanding its obligations under a National Pollutant Discharge Elimination System (NPDES) permit for its municipal separate storm sewer system (MS4) in the Kahului-Pāʻia urbanized area.
• Haley & Aldrich personnel, who had worked on other MS4 programs in Hawaii, understood the County of Maui’s operations and how the county could take advantage of existing programs and practices to fulfill many of the new MS4 permit requirements. Our practical and cost-saving approach led the county to select our staff to assist in managing MS4 permit compliance.
• Our stormwater professionals managed the initial NPDES application and have counseled on all aspects of the county’s permit and stormwater program since 2014 — providing essential insight to help the county protect Maui’s water quality.
• The county relies on us to develop stormwater management plans, survey and map stormwater infrastructure, create site-specific best management practice plans, train county staff, consult with stakeholders, and develop public education and outreach programs. We also work productively with regulators and assist the county with permit renewal and reporting requirements.
• This long partnership has built a comprehensive program that protects water quality and fosters public awareness to safeguard Maui’s cherished environment. The Hawaii Department of Health, which provides regulatory oversight, has called it a model program.
