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.
