Crystal Warren, TDEC-DWR-MEFO | May 16, 2019
TDEC exists to enhance the quality of life for citizens of Tennessee and to be stewards of our natural environment by:
• Protecting and improving the quality of Tennessee’s air, land, and water through a responsible regulatory system;
• Protecting and promoting human health and safety;
• Conserving and promoting natural, cultural and historic resources; and
• Providing a variety of quality outdoor recreational experiences.
• All new and existing point source industrial stormwater discharges associated with industrial activity require an NPDES Stormwater Permit from the Tennessee Division of Water Resources. Most common is a general permit which is available to almost any industry, but there is also an option for an individual permit,
• Based on Standard Industrial Classification Code (SIC)
• 2,265 Active permits, statewide
• 607 No Exposure certifications, statewide

Industrial Activities at Facility
• A SWPPP is a narrative document that basically explains what potential pollutants are located at a facility and what measures will taken to prevent pollution from occurring.
• Must be developed, maintained, and kept on-site
• Must be signed and certified by an appropriate person
