Proper management of stormwater is necessary and required by New Jersey State Law to prevent contaminants on impermeable surfaces from reaching and impacting nearby water systems. The requirements imposed by NJPDES General Stormwater permits can encompass both complex engineering designs and comparatively simpler but costly public and employee education programs. The following are some of the requirements that can be included in a NJPDES General Stormwater Permit:

• Development of and adherence to a Stormwater Pollution Prevention Plan
• Annual reports and certifications
• Local public education
• Pet waste control
• Litter pickup
• Improper disposal control
• Wildlife feeding control
• Outfall mapping
• Prevention/elimination of illicit connections
• Catch basin cleaning
• Outfall pipe stream scouring remediation
• Employee training

Relatively new state regulations that are designed to protect streams and floodplains can also impact the cost and complexity of stormwater management systems by requiring outfalls to be positioned in such a way as to protect these environmental features.

SAI Engineering staff have extensive knowledge of and experience with NJDEP Stormwater regulations. Our projects have ranged in size from designing a small spray irrigation field to an expansive retail development in an urban landscape.
