All users of the POTW will comply with all standards
and requirements of the Act and standards and requirements promulgated
pursuant to the Act.
No person shall discharge, directly or indirectly,
into the POTW wastewater containing any of the following substances
in concentrations exceeding those specified below on either a daily
or an instantaneous basis. Concentration limits are applicable to
wastewater effluents at the point just prior to discharge into the
POTW (end of pipe concentrations).

NOTES:

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 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
period.

Exceedances of these parameters may require
influent background samples to be taken at the facility where the
exceedance occurred.

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. All interceptors shall be of type and capacity
approved by the City Engineer and shall be so located to be easily
accessible for cleaning and inspection. Grease and oil interceptors
shall be constructed of impervious materials capable of withstanding
abrupt and extreme changes of temperature. They shall be of substantial
construction, watertight, and equipped with removable covers which,
when mounted in place, shall be gastight and watertight. Such interceptors
shall be inspected, cleaned, and repaired regularly, as needed, by
the owner at his expense.
No person shall discharge substances directly
into a manhole or other opening in a public sewer other than through
an approved building sewer.
Any person engaged in the hauling of septage wastes to the POTW must obtain a permit to do so. A hauler shall obtain a permit from the City of Norwich. In addition to Article
X of this chapter, permitted haulers shall be responsible for complying with all the terms and conditions contained in the permit. Any person discharging to the POTW without a permit will be subject to the penalties provided for in Article
XI of this chapter. All holding tank waste discharged to the POTW shall be discharged at the treatment facility at locations designated by the Superintendent. The discharge of hazardous wastes (as defined in Section 1004 of the Resource Conservation and Recovery Act) by septage haulers is prohibited. Each separate load of holding tank waste shall be registered with the operator of the treatment facility. The user shall pay the applicable charges or dumping fees and shall meet such other conditions as required by the City. The Superintendent shall have the right to inquire about the type of waste, the approximate volumes, and the origin of holding tank waste. The transporter of such wastes shall also have a waste transporting permit (6 NYCRR Part 364) issued by the DEC.
