(A) Limitations may be expressed in terms of mass and/or concentration as deemed appropriate by the POTW.
(B) No user shall discharge wastewater except in accordance with a permit or authorization.
(C) The federal categorical pretreatment standards may establish limits for various parameters. Any user subject to these federal standards will be required to meet the established limits through a permit issued by the POTW. In addition, the POTW may limit the discharge of other specific substances on a case-by-case basis, if the discharge of that substance would interfere with the proper function of the sewer collection system, contaminate sludge, pose a nuisance or health risk to employees or neighbors of the POTW, or violate any receiving stream water quality standard.
