(2) Analytical monitoring - Test Procedures for the Analysis of Pollutants - Test procedures 
for the analysis of pollutants shall conform to regulations published pursuant to Section 
304 (h) of the Clean Water Act (the "Act"), as amended, under which such procedures 
may be required. Pollutant parameters shall be determined using sufficiently sensitive 
methods in Title 40 C.F.R.    § 136, as amended, and promulgated pursuant to Section 304 
(h) of the Act. The chosen methods must be sufficiently sensitive as required in state rule 
0400-40-03-.05(8). 
(3) Aquatic Resource Alteration Permit (ARAP) - physical alterations to properties of the 
waters of the state require an ARAP or a §401 Water Quality Certification (§401 
certification).  ARAP means a permit issued pursuant to T.C.A. § 69-3-108 of the Act, 
which authorizes the alteration of properties of waters of the state that result from 
activities other than discharges of wastewater through a pipe, ditch, or other conveyance. 
(4) As built plans (record drawings) mean drawings depicting conditions as they were 
actually constructed. 
(5) Best Management Practices (“BMPs”) means schedules of activities, prohibitions of 
practices, maintenance procedures and other management practices to prevent or reduce 
the discharge of pollutants to waters of the state. BMPs also include treatment 
requirements, operating procedures; and practices to control plant site runoff, spillage, 
leaks, sludge or waste disposal, or drainage from raw material storage. BMPs include 
source control practices (non-structural BMPs) and engineered structures designed to 
treat runoff.  
(a) Structural BMPs are facilities that help prevent pollutants in stormwater runoff 
from leaving the site. 
(b) Non-structural BMPs are techniques, activities and processes that reduce 
pollutants at the source. 
(6) BMP Manual provides technical guidance including additional policies, criteria, 
standards, specifications, constants, and information for the proper implementation of the 
requirements of the National Pollution Discharge Elimination System permit (NPDES) 
and applicable regulations, 40 CFR § 122 as applicable for stormwater discharges. 
(7) Borrow Pit is an excavation from which erodible material (typically soil) is removed to 
be fill for another site. There is no processing or separation of erodible material 
conducted at the site. Given the nature of activity and pollutants present at such 
excavation, a borrow pit is considered a construction activity. 
(8) Buffer Zone or Water Quality Riparian Buffer is a permanent strip of natural perennial 
vegetation, adjacent to a stream, river, wetland, pond, or lake that contains dense 
vegetation made up of grass, shrubs, and/or trees. The purpose of a water quality riparian 
buffer is to maintain existing water quality by minimizing risk of any potential sediments, 
nutrients or other pollutants reaching adjacent surface waters and to further prevent 
negative water quality impacts by providing canopy over adjacent waters.
