The time is here to comply with the NPDES permit requirements!

The new Phase II NPDES permit requirements recently went into affect immediately placing new and additional responsibilities on municipalities and the owners/ operators of separate storm sewer systems (MS4s).

The purpose of the Phase II rules is to improve the water quality of streams, rivers and other receiving waters, in order to protect and enhance their associated aquatic habitats through the increased control of unregulated sources of stormwater discharge. Namely, these numerous stormwater outfalls and discharges occur throughout developed areas. The pollutants commonly occurring in stormwater discharge include nutrients, petroleum hydrocarbons, heavy metals, pesticides and sediment. These pollutants originate from diffuse and ubiquitous sources including the lawns, roads and parking lots of our suburban and urban landscapes. Construction sites are also targeted under Phase II, due to the large amount of sediment often associated with runoff from areas under development. While these new rules are enforced nationwide, it is up to individual affected entities to implement this upcoming program.

Princeton Hydro provides the technical "know-how" needed to comply with all of the requirements of the new stormwater regulations. We can assist you in stormwater planning activities, including the development of stormwater management ordinances. Using our GPS equipment, we can identify and map the location of all outfalls, and then using a specially designed, GIS integrated database system, catalog the outfalls and track related compliance activities such as inspections, repairs, retrofits and even monitoring. Our engineers can design infiltration/recharge, rain gardens, created wetlands, vegetated basins, and sandfilters. Finally, you can benefit from our long history of public outreach and our experience in the development of public educational materials on non-point source pollution and its abatement.

For further information on the Phase II NPDES program, stormwater BMPs, and Princeton Hydro’s ability to assist you in compliance with the new stormwater regulations, please take the time to refer to the numerous related articles and presentations.
