Except upon the issuance of a permit therefor by the Director
and upon such terms and conditions as may be established by the Director
in the issuance of such a permit, it shall be unlawful for any person:
A. To discharge sewage directly into the district sewerage system.
B. To discharge directly or indirectly into the district sewerage system, or tributary public sewers or into any private sewer or any combined sewer, sewage combined with industrial wastewater or other wastes, which, at the point of discharge, exceed the concentration limits prescribed for normal sewage under Article
II herein, or fall within the categories prohibited or restricted under Article
VI herein. Each significant industrial user proposing to connect to or to contribute to the POTW shall obtain an industrial wastewater permit before connecting to or contributing to the POTW. Each existing significant industrial user connected to or contributing to the POTW shall obtain an industrial wastewater permit within 180 days after the effective date of these rules and regulations.
In compliance with Public Laws 84-660 and 92-500 of the Water
Pollution Control Acts and amendments thereto, these regulations adopt
and use as a guide the National Pretreatment Standards and the Environmental
Protection Agency's (EPA) Pretreatment Guidelines. The district
recognizes that, in some cases, these pretreatment standards may not
be sufficient to protect the operation of its POTW treatment plant
and enable it to comply with the terms of the SPDES permit. In such
cases, the District reserves the right to impose more stringent pretreatment
standards than those specified in the EPA regulations.
