A coastal spill of 50,000 gallons is classified as which discharge?

• A. Minor discharge coastal
• B. Medium discharge coastal
• C. Major discharge coastal
• D. Not classified

Answer: (B)

Discharge classification for coastal spills depends on the amount released and the setting. Spills are grouped into tiers like minor, medium, and major, with each level guiding the expected response.

Fifty thousand gallons is larger than what would typically be tagged as a minor spill, which covers smaller, easily contained releases. But it isn’t large enough to be considered a major coastal discharge, which involves far bigger releases and a correspondingly larger, more complex response. So this amount fits the medium coastal discharge category, signaling a substantial response but not the largest scale.

In other words, the volume sits in the middle tier: enough to require significant containment and cleanup efforts and coordination, but not at the extreme magnitude that would trigger major-scale actions.
