|
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 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.
|
3
|
As determined on a grab sample taken from the user's discharge
at any time during the daily operational and/or production period.
