King County wastewater discharge limits and regulations

KCIW signature requirements and delegating signatory authority

The King County Industrial Waste Program (KCIW) issues discharge authorizations to area hospitals that discharge wastewater to the King County sewage system.

The discharge authorizations serve to ensure that hospital discharges meet the county's local limits for pollutants, to protect human health and the environment and the public's investment in wastewater facilities. A King County Public Rule regulates such discharges to the sewer.
