behalf.
COMPATIBLE POLLUTANT
A substance amenable to treatment in the wastewater treatment
facility, such as BOD, suspended solids, pH and fecal coliform bacteria,
plus additional pollutants identified in the NPDES permit of the wastewater
treatment facility, which was designed to treat such pollutants, and
in fact does remove such pollutants to an acceptable degree. These
additional pollutants may include COD, total organic carbon, phosphorus
and phosphorus compounds, nitrogen and nitrogen compounds, and fats,
oils and grease of animal or vegetable origin.
COMPOSITE SAMPLE
(1)
For continuous discharges, a sample collected via an automatic
sampler over the period of discharge contained within a twenty-four-hour

of aliquots if approved by the City) taken at a rate proportional
to the waste stream flow; or

combined prior to laboratory analysis using protocols (including appropriate
preservation) specified in 40 CFR Part 136 and appropriate EPA guidance.

during the period of discharge contained in a twenty-four-hour period.
Compliance with a daily maximum condition of discharge for a grab
sample may alternatively apply to the analytical test result of an

The building, structure, facility, or installation is constructed
at a site at which no existing source is located;
b.
The building, structure, facility or installation totally replaces
the production equipment or processes that cause the discharge of
pollutants at an existing source; or
