Airport Tenant Environmental Resources
SEA Airport operates under facility specific environmental regulations and initiatives. This section provides guidance to these items.
Stormwater Program
SEA operates under an individual National Pollutant Discharge Elimination System (NPDES) Permit No. WA0024651 issued to the Port of Seattle by the Department of Ecology. All tenant activities are covered under the Airport's Stormwater Pollution Prevention Plan (SWPPP). The SWPPP identifies required and recommended Best Management Practices (BMPs) to be implemented as appropriate for each tenant activity. Because airport tenant activities vary, each tenant is required to have a Water Pollution Control Plan (WPCP) that outlines BMPs specific to the tenants’ operations at the airport. The WPCP serves as the tenant's version of the SWPPP. Port Environmental Staff conduct comprehensive inspections of tenant facilities to determine tenant compliance with permit requirements based on implementation of the WPCP.
More information about the drainage system can be found by exploring SEA Airport's Stormwater Management Program.
Quarterly Environmental Forum
The Port of Seattle Aviation Environmental department hosts a quarterly environmental forum to which all airport tenants are welcome. This is an opportunity to meet Port staff and learn about resources to help both tenants and the Port meet our environmental compliance and sustainability goals.
IWS Discharge Request
Tenants wanting to discharge pollutants or potential pollutants to the Industrial Wastewater System (IWS) must fill out an IWS Discharge Request form seven days prior to the release. This includes, but is not limited to, grease, oil, fuel, detergents, deicing fluids, etc. The IWS system may be used to manage unintentional spills and discharges of fuel that cannot be safely and effectively managed otherwise, consistent with established and applicable spill control planning and BMPs.
SWPPP Training
SEA Airport Stormwater Pollution Prevention Plan training course fulfills the training requirements of our airport's NPDES Permit. This training should be completed annually by tenants who have the potential to impact SEA’s drainage system.
Aircraft Deicing and Anti-Icing
The NPDES Permit requires the Port to track and submit aircraft deicing/anti-icing fluid volumes applied to aircraft. Prior to each winter season, deicing/anti-icing applicators must provide the aircraft deicer types and dilutions. From October through April, tenants submit a daily glycol application report to Port Environmental staff monthly. Tenants can submit the monthly glycol application report using the Port provided Deicing Report template.
More information about aircraft de-icing can be found the All You Never Wanted to Know about Airplane De-Icing blog.
Approved Ground Deicers
Tenants can refer to SEA’s Deicing Memo for Port approved ground deicers and anti-icers.
