The Warren County Department of Public Works is responsible for developing and implementing the County's Stormwater Pollution Management Plan. 

What is Stormwater?

The official definition of stormwater under the N.J.A.C. 7:14A rules is as follows:

'Stormwater' means water resulting from precipitation (including rain and snow) that runs off the land's surface, is transmitted to the subsurface, or is captured by separate storm sewers or other sewage or drainage facilities, or conveyed by snow removal equipment.

Stormwater Management

Stormwater management is the control and use of stormwater runoff.  It includes maintaining and improving stormwater systems and regulating the collection, storage and movement of stormwater.

The Municipal Stormwater Regulation Program was developed in response to the U.S. EPA's Phase II rules, published in December 1999.   The EPA issued final stormwater rules on February 2, 2004 and four NJDEP general permits authorizing stormwater discharges away from Tier A and Tier B muncipalities, as well as public complexes and highway agencies that discharge stormwater from municipal sewer systems.  The general permits also address stormwater quality issues related to new development, redevelopment and existing development.  The Division of Bridges and Roads is responsible for adhering to the state-mandated Stormwater Pollution Prevention Plan (SPPPS), which details activities in a report submitted to the state annually.  Access the annual Stormwater Pollution Prevention Plan here.

Highway agencies include County, State, Interstate and Federal government agencies that operate highways and other thoroughfares.  

The Stormwater Pollution Prevention Plan report includes:

• Inspection of all catch basins on County roads
• Amount of material (in tons) removed from the basins
• Number of catch basin repairs
• Number of new basins constructed, and location
• Amount of sweepings material (tons) removed from the roadway by month
• Mapping of all outfalls under the County's jurisdiction
• Areas of erosion and scouring that have been repaired
• A roadside vegetation program
• Conduct annual employee training on stormwater issues and management
• Provide standard operating procedures for vehicle and equipment fueling
• Provide standard operating procedures for vehicle maintenance
• Provide standard operating procedures for good housekeeping
