Marinas and Class 4 facilities

Our requirements and recommendations for marinas and Class 4 facilities help prevent and prepare for spills of oil or hazardous material.

State requirements for Class 4 facilities

Class 4 facilities are marinas or other small fueling facilities that transfer oil to non-recreational vessels with a total oil capacity of less than 10,500 gallons. Here's what we require for Class 4 facilities:
Spill response


Our facility oil handling standards rule requires Class 4 facilities to keep enough spill response equipment on standby to clean up a spill of 25 gallons. Class 4 facilities are required to:

  • Inspect, maintain, and replace response equipment as needed.
  • Keep a list of the locations of the response equipment on site.

Notifications at the dock

Our facility oil handling standards rule requires Class 4 facilities to post spill notification information at the dock for fueling customers. Required notifications:

  • Call 911, if necessary.
  • Notify marina manager/owner or after-hours contact.
  • Contact the spill response contractor, if necessary.
  • Report spill to BOTH of the following numbers:
    • 800-424-8802 (U.S. Coast Guard National Response Center)
    • 800-OILS-911 (Washington Division of Emergency Management)

Facility inspections Oil transfers Staff training

We do not require Class 4 facilities to have a spill response plan. We do recommend that Class 4 facilities and marinas develop and maintain response plans, which help facilities meet our regulatory requirements and be better prepared to respond to spills.

Response plan

Class 4 marinas are not required to submit a written spill response plan for our approval, but in most cases, a written response plan will help owners and operators comply with our rules. We strongly recommend that each facility develop a written plan.

Response plans include this information:

  • Initial actions list
  • Required notifications and additional contact information
  • Emergency shutdown procedures
  • Facility description and site plan
  • Response equipment and equipment maintenance program
  • Sensitive areas
  • Waste disposal
  • Training
  • Material safety data sheets (MSDS)
  • Semi-annual reporting requirements
  • Plan review and update
Our spill response guide for Class 4 facilities will help you develop a response plan for your facility.
