SPDES Permit Program: Is This Project Major or Minor?
Minor SPDES projects include:
- discharges of less than 10,000 gallons per day of sewage effluent, without the admixture of industrial wastes or other wastes, to ground water. Such projects may qualify for the P/C/I SPDES General Permit.
- ballast discharges.
All Other SPDES Projects are Major.
