NJDEP Stormwater Initiatives: MS4s & GIS Mid-Atlantic Geospatial Transportation Users Group GIS Day - November 5, 2015 NJ Department of Environmental Protection Bureau of Nonpoint Pollution Control Kyra Hoffmann
Municipal Stormwater Regulation Program MS4 Basics Permit Renewal Stormwater Facilities Mapping & Inventory
Municipal Separate Storm Sewer System MS4 is a conveyance or system of conveyances that ultimately discharge to waters of the State and Is designed or used to collect or convey stormwater (including roads; curbs; gutters; ditches; manmade channels; stormwater management facilities; or storm drains) Is not a combined sewer
Municipal Stormwater Permits NJDEP issued four MS4 permits- Tier A Municipalities (461), Urban & coastal Tier B Municipalities (101), Rural & non-coastal Public Complexes (71) Universities, hospitals Highway Agencies (33) Counties, NJDOT, SJTA
Municipal Stormwater Permits Stormwater Quality Issues related to new development, redevelopment and existing development. NJPDES Rules (N.J.A.C. 7:14A) comply with USEPA s Phase II stormwater rules by incorporating USEPA s Six Minimum Standards as Statewide Basic Requirements (SBRs) NJ Stormwater Regulations (N.J.A.C. 7:8)
Municipal Stormwater Permits Stormwater Quality Issues related to new development, redevelopment and existing development including good housekeeping & pollution prevention. Municipalities are the first line of defense for stormwater protection.
Municipal Stormwater Permits Why do all this? Healthy water Healthy people
Municipal Stormwater Permits: Tier A Post Construction Stormwater Management in New Development and Redevelopment Local Public Education Improper Disposal of Waste Solids and Floatables Controls Maintenance Yard Operations Employee Training Public Notice
Municipal Stormwater Permits Stormwater Pollution Prevention Plan

Statewide Basic Requirements Public Education and Outreach Local Public Education and Outreach
Statewide Basic Requirements Construction Site Runoff Construction Site Stormwater Runoff Construction Activity Stormwater General Permit (5G3) Soil Conservation Districts
Statewide Basic Requirements Post-Construction Stormwater Measures & Management Post Construction Stormwater Management To address stormwater management from new development and redevelopment Ensure compliance with N.J.A.C. 7:8
Statewide Basic Requirements Pollution Prevention & Good Housekeeping
Statewide Basic Requirements Pollution Prevention & Good Housekeeping Stormwater Facilities Maintenance: Ensure long-term maintenance of all BMPs own and operated Must be maintained as designed Must have maintenance plan
Statewide Basic Requirements MS4 Outfall Pipe Mapping and Illicit Discharge Detection and Elimination Outfall Pipe Mapping Ongoing Inspection Response to Complaints
Tier A Permit Renewal Comprehensive mapping and inventory of new and existing stormwater facilities Clarified stormwater facility maintenance language Greater flexibility in the frequency of storm drain inlet and catch basin inspection and cleaning Expanded maintenance yard module Major Development Stormwater Summary Form Expanded and greater flexibility for training TMDL Look-Up Tool
Tier A Permit Renewal MS4 Mapping and Inventory Comprehensive Mapping of Stormwater Facilities Enhance MS4 Asset Management for Better planning and maintenance Response to flooding and other emergencies Assist with illicit discharge detection
Tier A Permit Renewal Stormwater Facilities Mapping What needs to be mapped? Outfall pipes Stormwater Basins Green Infrastructure
Tier A Permit Renewal Stormwater Facilities Mapping What needs to be mapped? Subsurface Retention/Detention Systems Manufactured Treatment Devices SW Treatment Train Components
Tier A Permit Renewal Stormwater Facilities Mapping What info must be included? Type of SW facility Owner Location Includes both municipally owned and operated and Privately owned and operated (and not subject to another NJPDES permit)
Tier A Permit Renewal Stormwater Facilities Mapping Submittal Requirements Maintain in an electronic format Provide to NJDEP as part of Annual Report and Certification Daisy Township Springfield Boro Elk Village DEP
Tier A Permit Renewal Stormwater Facilities Mapping Has your organization mapped any of the following? storm drain inlets? stormwater conveyance systems? stormwater management basins? subsurface infiltration/detention systems? manufactured treatment devices? green infrastructure? outfalls pipes or other stormwater discharge points? other features? Do you have a schema or data dictionary for the layers?
Tier A Permit Renewal Stormwater Facilities Mapping Does your organization share any of the data collected with municipalities? With DEP? Does your organization have a program to let municipalities borrow GPS units? What GPS units are available to the municipalities? What software do you use for GPS? (ArcPad, Terrasync, other app) Do you process the GPS data for them? How do you supply the data back to the municipalities? (hard copy map, kmz, ArcGIS Online, other way) Does your organization provide training to municipalities on how to use GPS units?
Tier A Permit Renewal Stormwater Facilities Mapping Does your Organization map any stormwater facilities that it does not own/operate? What is the level of effort entailed in stormwater facility mapping (example: #hours/outfall)? If the NJDEP were supplying data to you, what is the preferred format? What level of accuracy should be used? Enhanced cell phones? Desktop exercise? Topline GPS units?
