Do Not Start a Project Before Obtaining a Permit
You must obtain all necessary permits before commencing work on a project that requires any DEC permit. Persons commencing work on such a project before obtaining the required permits, and any contractors engaged in such work, are subject to enforcement action by the DEC. Such action may include:
- Civil or criminal court action, or both,
- Fines, or
- An order to remove structures or materials or perform other remedial action, or both a fine and an order.
No SPDES permit is required for a facility whose treatment system has a design flow of total discharges to ground water of less than 1,000 gallons per day of sewage-wastewater containing no industrial or other non-sewage wastes.
However, these discharges may require approval from the appropriate city health department, county health department, or district office of the New York State Department of Health before a system (cesspool, septic system, etc.) can be built. They may also require other DEC permits or approvals from other agencies.
