NOTES:
1 Except for chromium (hex), all concentrations
listed for metallic substances shall be as "total metal," which shall be defined
as the value measured in a sample acidified to a pH value of two point zero
(2.0) or less, without prior filtration.
|
---|
2 As determined on a composite sample taken
from the user's daily discharge over a typical operational and/or production
day.
3 As determined on a grab sample taken from
the user's discharge at any time during the daily operational and/or
production period.
|
4 Other substances which may be limited are
antibiotic chemical compounds which, upon acidification, alkalinization, oxidation
or reduction, in the discharge or after admixture with wastewater and its
components in the POTW, produce toxic, flammable or explosive compounds; pesticides,
including algicides, fungicides, herbicides, insecticides or rodenticides;
polyaromatic hydrocarbons; or viable pathogenic organisms from industrial
processes or hospital procedures.
