(A) A user of the POTW, whether or not that user is subject to national categorical standards or state, local, or any other national pretreatment standard or requirement, shall not allow the introduction of the following into the POTW:
(1) A pollutant from any source of nondomestic wastewaters that could pass through or cause interference with the operation or performance of the POTW;
(2) Any pollutant that could create a fire or explosion hazard, including waste streams with a closed cup flashpoint of less than 140°F (60°C) using the test methods in 40 CFR 261.21;
(3) Any pollutant that could cause corrosive structural damage to the town’s wastewater facilities, including a discharge with pH lower than 5.0 or more than 11.0, unless the town’s wastewater facilities have been specifically designed to accommodate such a discharge;
(4) A solid or viscous pollutant in an amount that could cause obstruction to the flow in a sewer or other interference with the operation of the POTW;
(5) A pollutant, including an oxygen demanding pollutant (such as biochemical oxygen demand) released in a discharge at a flow rate or pollutant concentration that could cause interference in the POTW;
(6) Contain heat in an amount that could:
(a) Inhibit biological activity in the POTW and result in interference or damage to the POTW; or
(b) Exceed 40°C or 104°F at the POTW treatment plant unless the Commissioner, upon request of the POTW, approves alternate temperature limits.
(7) Petroleum, oil, nonbiodegradable cutting oil, or products of mineral oil origin in an amount that could cause interference or pass through;
(8) Contain more than 100 milligrams per liter of nonbiodegradable oils of mineral or petroleum origin;
(9) A pollutant that could result in the presence of toxic gases, vapors, or fumes within the POTW in a quantity that may cause acute worker health and safety problems;
(10) Contain floatable oils, fat, or grease;
(11) Contain radioactive wastes in harmful quantities as defined by applicable state and federal guidelines;
(12) Contain any garbage that has not been properly shredded;
(13) A trucked or hauled pollutant, except:
(a) With the permission of the POTW; and
(b) When introduced to the POTW at a discharge point designated by the POTW.
(14) Noxious or malodorous liquids, gases, solids, or other wastewater which, either singly or by interaction with other wastes, are sufficient to create a public nuisance or a hazard to life, or to prevent entry into the sewers for maintenance or repair; and/or
(15) Wastewater which imparts color which cannot be removed by the treatment process, such as, but not limited to, dye wastes and vegetable tanning solutions, which consequently imparts color to the treatment plant’s effluent, thereby violating the town’s NPDES permit.
(B) The Town of Hagerstown reserves the right to establish, by ordinance or in individual wastewater discharge permits, more stringent standards or requirements on discharges to the POTW consistent with the purpose of this section.
(C) If in establishing discharge restrictions, discharge limits or pretreatment standards pursuant to this section, the Manager establishes concentration limits to be met by an industrial user, the Manager, in lieu of concentration limits, may establish mass limits of comparable stringency for an individual industrial user at the request of the user.
