General
■ What is stormwater?– Storm water is rainfall runoff, snow melt runoff, and surface
runoff and drainage
![Page 5: NEWEA 2014 Spring Conference](https://reader033.vdocument.in/reader033/viewer/2022060116/55843300d8b42a56178b4620/html5/thumbnails/5.jpg)
Why Do We Care About Stormwater?
■ Contaminated stormwater is a significant source of surface water pollution
■ Pollution on the land can end up in stormwater runoff and into our water bodies
![Page 6: NEWEA 2014 Spring Conference](https://reader033.vdocument.in/reader033/viewer/2022060116/55843300d8b42a56178b4620/html5/thumbnails/6.jpg)
Regulatory Background
■ Point Source Pollution– Water Quality Act of 1965 – Federal Water Pollution Control Act Amendments of 1972– Clean Water Act of 1977
■ Non-Point Source Pollution– Water Quality Act of 1987 – Phase 1 (1990)
» Medium and Large MS4s » Industrial Stormwater Dischargers» Construction Sites of 5+ acres

NPDES - Industrial
■ Permitting Options? – Multi-Sector General Permit (MSGP)
– Federal or state
– Meant to be easy
– No Exposure Certification (NEC)
– Still need to file!
– Individual Wastewater Discharge Permit
– Don’t need these for stormwater
![Page 12: NEWEA 2014 Spring Conference](https://reader033.vdocument.in/reader033/viewer/2022060116/55843300d8b42a56178b4620/html5/thumbnails/12.jpg)
Sectors & SIC
■ What is an SIC code? – A Standard Industrial Classification code or SIC code is a four-
digit code describing the activities taking place at a facility. Facilities conducting multiple operations may have multiple SIC codes, one describing each activity.
■ What is a Primary SIC code? – A primary SIC code describes the activity that generates the
highest net revenue at a facility.

Sampling & Monitoring
■ What is a Representative Rain Event? – 0.1” of measured precipitation– Occurs at least 72 hours from the last 0.1 inch or
more of measurable precipitation– Sufficient enough discharge from the outfall to obtain
a sample
