(42) Stream as defined by TCA 69-3-103(38) “stream” means a surface water that is 
not a wet weather conveyance.   
(43) Stormwater associated with industrial activity is defined in 40 C.F.R. 
122.26(b)(14) and incorporated here by reference. Most relevant to the City is 40 C.F.R. 
122.26(b)(14)(x), which relates to construction activity including clearing, grading, 
filling and excavation activities, including borrow pits containing erodible material. 
Disturbance of soil for the purpose of crop production is exempt from NPDES permit 
requirements, but stormwater discharges from agriculture-related activities that involve 
construction of structures (e.g., barn construction, road construction, pond construction) 
are considered associated with industrial (construction) activity. Maintenance to the 
original line and grade, hydraulic capacity; or to the original purpose of the facility (e.g., 
re-clearing, minor excavation performed around an existing structure necessary for 
maintenance or repair and repaving of an existing road) is not considered a construction 
activity. 
(44) Construction stormwater discharge-related activities mean activities that cause, 
contribute to or result in point source stormwater pollutant discharges. These activities 
may include excavation, site development, grading and other surface disturbance 
activities; and activities to control stormwater including the siting, construction and 
operation of best management practices (BMPs). 
(45) Stormwater Pollution Prevention Plan (SWPPP) is a written site-specific plan 
required by the Tennessee Construction General Permit (CGP) that includes a narrative 
pollution prevention plan and graphical erosion and sediment control plan. In its basic 
form, the plan contains a site map, a description of construction activities that could 
introduce pollutants to stormwater runoff, a description of measures or practices to 
control these pollutants, and erosion and sediment control plans and specifications.  The 
SWPPP should be prepared in accordance with the Tennessee Erosion and Sediment 
Control Handbook (latest edition). 
(46) Take of an endangered species means to harass, harm, pursue, hunt, shoot, wound, 
kill, trap, capture or collect, or attempt to engage in any such conduct. 
(47) Tennessee Erosion and Sediment Control (TDESC) Handbook is a guidance 
issued by the Division of Water Resources for the purpose of developing Stormwater 
Pollution Prevention Plans and Erosion and Sediment Control Plans required by the 
Construction General Permit. 
(48) Temporary stabilization is achieved when vegetation or non-erodible surface has 
been established on the area of disturbance and construction activity has temporarily 
ceased. Under certain conditions, temporary stabilization is required when construction 
activities temporarily cease.  
(49) Treatment chemicals are polymers, flocculants or other chemicals used to reduce 
turbidity in stormwater discharges by chemically bonding to suspended silts and other
