1 The Urban Connection: NPDES and Storm Water in the State of Delaware Sandra M. Goodrow, Ph.D., C.F.M. Environmental Scientist IV Surface Water Discharge Section Presented at the Third Annual DEAWRA Symposium November 19 th, 2013

2 Overview of NPDES Programs National Pollutant Discharge Elimination System A system of regulating point sources of pollution to surface waters Typical point sources include treated process water discharges from industry What is a permit? A. An agreement B. A license C. A stick D. All of the above

3 NPDES Storm Water Program Phase I 1990 Industrial 11 Categories, including construction Large and Medium MS4s Medium: Population of 10, ,999 Large: Population of 250,000 or more Phase II 1998 Small MS4s in Urban Areas So, is it the population or…..

4 Stormwater is the Urban Connection We have met the enemy- imperviousness (Tom Shueller, Center for Watershed Protection)

5 Linking Land Use to Water Quality

6 Stormwater is the Urban Connection What is Urban? Higher Population Density May be cities, towns or sprawl

7 The Bureau of Census Released its 2010 Census in late 2011 Some communities in Delaware that were not currently regulated grew in population, so that they now require permit coverage Urban Area

8 Phase I 1990 Large and Medium MS4s Industrial Facilities Intended to cover the larger source contributors Phase Small MS4s in Urban Areas Intended to more fully cover the urban contribution

9 Industrial Storm Water Program Standard Industrial Classification (SIC) Codes or Activity Code Examples of Sectors (or Classes) of SIC Codes: Sector D: Asphalt Paving Sector J: Mineral Mining Sector M: Automobile Salvage Yards Sector P: Land Transportation and Warehousing

10 Provisions Under the Industrial Storm Water Program Limits on Eligibility to Discharge (e.g. TMDLs) No Exposure Certification SWPP/SWMP/SWPP&MP Maps, drainage, outfalls, training… Effluent Monitoring Specific to SIC Code Inspections

11

12 Currently, DE holds permits for 362 Active Facilities 103 of these are No Exposure Certified The Industrial Storm Water Regulations are currently being revised.

13 Current MS4s in Delaware Phase I (Issued May 7, 2013) New Castle County DelDOT Towns of Bellefonte, Elsmere and Newport Cities of Delaware City, New Castle and Wilmington Phase II (Issued ~2003) City of Newark Town of Middletown Kent County DelDOT City of Dover

14 Provisions of the MS4 Program Intent Authorized Discharges 6 Minimum Components 1. Public Education and Outreach 2. Public Involvement and Participation 3. Illicit Discharge, Detection and Elimination 4. Construction Site Stormwater Runoff Control 5. Post-Construction Storm Water Management 6. Pollution Prevention and Good Housekeeping For each Minimum Component: BMPs, goals, timelines and responsible party

15 Provisions of the MS4 Program Public Education and Outreach/Public Involvement and Participation Proper use of fertilizers and pesticides Public reporting of illicit discharges Stream clean ups Proper maintenance of BMPs Public review of SWPP&MP For Example:

16 Provisions of the MS4 Program Illicit Discharge, Detection and Elimination Ordinances Grass Clippings Commercial Facilities Mapping of all outfalls Development of a program to detect and report all illicit discharges For Example:

17 Provisions of the MS4 Program Construction Site Stormwater Runoff Control Post-Construction Storm Water Management Requires the review and approval of Sediment and Stormwater Plans according to standards set within the current Delaware Sediment and Stormwater Regulations Use and maintenance of BMPs Implement and enforce a program to address post construction stormwater runoff from new development and re-development projects

18 Provisions of the MS4 Program Pollution Prevention and Good Housekeeping A plan for all facilities owned or operated by permittee (Public Works yards, parks, composting areas…) A street cleaning program A program to manage snow and ice, including salt storage and alternate deicing practices For Example: And there could be more….

19 Whats NEW in the MS4 Business? 2010 National Census changes where the permits are required New State of Delaware Phase II MS4 General Permit almost ready for review!

20 So, now comes the 2010 Census And Delaware has grown…. Census tracts Urban Areas vs. Urban Clusters

22 How the NPDES Program Relates to other programs Watershed Implementation Plans TMDLs Use of Green Infrastructure

23 Take Home Reducing or reversing the impact of development is the intent of so many of our watershed programs The NPDES permit program can be used as a comprehensive guide as to how to get there
