Minor discharge for inland and coastal is defined as:

• A. Inland less than 2000 gallons; Coastal less than 20000 gallons
• B. Inland less than 500 gallons; Coastal less than 5000 gallons
• C. Inland less than 1000 gallons; Coastal less than 10000 gallons
• D. Inland less than 100 gallons; Coastal less than 1000 gallons

Answer: (C)

Discharge classifications hinge on volume and where the discharge occurs. A minor discharge is a small amount that stays within thresholds that don’t trigger the stricter major-discharge requirements. The limits reflect environmental considerations: inland waters are more sensitive and have less dilution, so the allowable minor amount is smaller; coastal waters can dilute more, so the limit is higher. Thus, inland minor discharge is defined as less than 1000 gallons, and coastal minor discharge as less than 10,000 gallons. Discharges above those thresholds would be treated as major and require additional reporting and cleanup actions.
