As used in this chapter, the following terms shall have the meanings
indicated:
ACT or THE ACT
The Federal Water Pollution Control Act, also known as the
"Clean Water Act," as amended, 33 U.S.C. § 1251 et seq.
ACUTE TOXICITY TEST
(1)
Involves two separate but simultaneously performed static, acute
screening tests. In each test* organisms basic to the aquatic food
chain are exposed to an aliquot of effluent/discharge to determine
the effect(s) of an effluent/discharge on the receiving stream and/or
microbial activity within the water pollution control facility. [*Test
performed on Daphnia pulex (larvae) and Pimephales promelas (fathead
minnows).]
(2)
The acute toxicity test will be a prime factor used in determining
the extent of pretreatment required of industrial/commercial users.
Sample collection, handling, and analytical techniques used to determine
the acute toxicity of the discharge shall be as prescribed in "Methods
for Measuring the Acute Toxicity of Effluents to Freshwater and Marine
Organisms" (EPA/600/4-85/013), unless otherwise specified in writing
by the DEEP or in the regulations of Connecticut state agencies.
BACKWATER VALVE
A backwater valve is a one-way flow control valve installed
in a drainage system, that under normal conditions allows the wastewater
to drain out of the system; however, if a reversed flow of drainage
water should occur, the valve will be forced closed and protect the
interior of the building from sewage backup.
BEST MANAGEMENT PRACTICES (BMP)

that are designed to prevent or minimize obstruction, damage, or excessive
maintenance of the sanitary sewer.

decomposable organic matter under aerobic conditions for five days.
The determination of BOD shall be performed in accordance with the
procedures prescribed in the latest edition of Standard Methods for
the Examination of Water and Wastewater.
BUILDING DRAIN
That part of the lowest horizontal piping of building plumbing
which receives the discharge from water fixtures and other sanitary
pipes inside the walls of the building and conveys it to the building
sewer lateral beginning five feet (1.5 meters) outside the inner face
