NOTES:
| |
(1)
|
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 2 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, except
for cyanide, total phenols, pH, oil and grease, which shall be determined
using grab samples.
|
(3)
|
As determined by an average of composite samples within a one-month
period.
|

|
Antibiotics
|

|
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,
rodenticides
|
