Full Breakdown
TDEC's Phase I and II MS4 list shows four separate Montgomery County permittees: City of Clarksville TNS075205, Montgomery County TNS075621, Fort Campbell Military Reservation TNS075817, and Austin Peay State University TNS088285. Inside the city limits the city is the permitting authority. Land disturbance over one acre, or under an acre within a common plan, triggers a storm water quality permit and post-construction treatment, plus water quality buffers under section 12-315. Hot spot land uses, including restaurants, gas stations, car washes and dry cleaners, need a quality permit at any size. All non-storm water discharges into the storm sewer are prohibited except for a listed set such as lawn watering and foundation drains.
Violations & Fines
Civil penalties of $50 to $5,000 per day, each day separate. The Director of Streets may block a discharge, issue stop work orders, and have utility service denied to a noncompliant property.
