H. Containing dyes or other materials with objectionable color, from any source that will result in a treatment plant effluent exceeding limits in compliance with applicable State or Federal regulations.
I Any substance which may cause the treatment plant’s effluent or any other product of the treatment plant, such as residues, sludges or scums, to be unsuitable for reclamation and reuse or to interfere with the reclamation process. In no case shall a substance discharged to the treatment plant cause the Township to be in noncompliance with sludge use or disposal criteria, guidelines or regulations affecting sludge use or disposal developed pursuant to the Solid Waste Disposal Act, the Clean Air Act, the Toxic Substances Control Act or Commonwealth criteria applicable to the sludge management method being used.
J. Containing radioactive substances and/or isotopes of such half-life or concentration that will result in a treatment plant effluent exceeding limits in compliance with applicable State or Federal regulations.

S. Containing any substance not mentioned in the foregoing list that will cause interference or pass through at the treatment plant and exceed the maximum permitted levels for such substance under the requirements of the EPA, the Commonwealth or other governmental agencies having jurisdiction.
T. Any other substance prohibited by resolution, rule, regulation or agreement of the Township hereafter enacted or adopted from time to time.
U. Sludges, screening or other residues from the pretreatment of industrial wastes.
V. Medical wastes, except as specifically authorized by the Township in a wastewater discharge permit.

The Township shall notify all affected users of the applicable reporting requirements under 40 CFR § 403.12.
5. No user shall ever increase the use of process water or, in any way, attempt to dilute a discharge as a partial or complete substitute for adequate treatment to achieve compliance with the limitations contained in the Federal Categorical Pretreatment Standards, or in any other pollutant-specific limitation developed by the Township or the Commonwealth.
6. Whenever a person is authorized by the Township and the appropriate governmental agencies to discharge any polluted water, domestic sanitary sewage or industrial waste containing any of the substances or possessing any of the characteristics referred to in subsection (2), such discharge shall be subject to the continuing approval, inspection and review of the Township. If, in the opinion of the Township, such discharges are causing or will cause damage to the treatment plant, or will cause the Township to be in violation of any agreement or order, the Township shall order the person causing such discharge to cease doing so forthwith, or to take other appropriate action, including exercising the remedies provided in the Connection Ordinance [Part 3A], or delegating to another party duties to take appropriate action, to eliminate the harmful discharge.

Such facilities for preliminary treatment and handling of industrial wastes shall be continuously maintained, at the sole expense of the owner, in good operating condition satisfactory to the Township. The Township shall have access to such facilities at reasonable times for purposes of inspection and sampling.
