Permitting Support & Compliance

KEI has considerable experience and expertise in supporting construction, industrial, and municipal clients during the wastewater and stormwater discharge permit application process, permit implementation, and compliance monitoring for discharges regulated by the NPDES or the Alaskan equivalent (APDES). Construction clients have included roadway and bridge transportation agencies and their contractors. Industrial clients have included those in the shipping, utility, and oil and gas industries along with aquaculture associations and log transfer facilities. Municipalities have included both large and small dischargers in Alaska, California, and Hawaii, including many stormwater and watershed programs.
