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.
|
3 The sum of the concentrations of chemicals,
as listed in the table List of Organic Chemicals Included in Total Toxic Organics
(TTO), on file in the village offices, cannot exceed 2.13 mg/l.
|
Except where expressly authorized to do so by an applicable pretreatment
standard, no user shall ever increase the use of process water or, in any
other way, attempt to dilute a discharge as a partial or complete substitute
for adequate treatment to achieve compliance with a pretreatment standard.
Dilution flow shall be considered to be inflow.
Grease, oil and sand interceptors shall be provided when, in the opinion
of the Superintendent, they are necessary for the proper handling of wastewater
containing excessive amounts of grease, flammable substances, sand or other
harmful substances; except that such interceptors shall not be required for
private living quarters or living units. The size, type and location of each
interceptor shall be approved by the Superintendent. All interceptors shall
be of the type and capacity approved by the Superintendent and shall be so
located to be easily accessible for cleaning and inspection. Interceptors
shall be sized and engineer based upon the anticipated load and/or conditions
of actual use. Such interceptors shall be inspected, cleaned and repaired
regularly, as needed, by the owner, at his expense.
