APDES permits regulate wastewater discharges to protect water quality, human health, and aquatic life and require facilities to monitor, report, and conduct proper operation and maintenance procedures. Permits are based on water quality standards and achievable treatment technologies. DEC strives for a full understanding of local conditions and concerns, encourages tribal participation in the permitting process, and provides opportunities for involvement. Tribal involvement enhances the permit process and improves protection of Alaska’s natural resources.
