(1) Inflow and Infiltration. Each new Sanitary Sewer and replacement or extension that discharges directly or indirectly to the Authority Sewerage System, shall be designed and constructed so as to minimize, to the maximum extent possible, all Inflow and Infiltration into the Municipal or Authority Sewerage System. The owner and/or operator of any Sewerage System which discharges directly or indirectly to the Authority Sewerage System shall operate and maintain the System so as to eliminate any and all contaminated Inflow and Infiltration and any Inflow and Infiltration in quantities above that allowed by the Authority.

(2) Storm Sewers, Sanitary Sewers, and Combined Sewers. The plumbing of any estate or premises discharging directly or indirectly to the Authority Sewerage System shall be arranged so as to keep any groundwater, storm water, surface water, roof and surface runoff, uncontaminated Cooling Water, Non-contact Cooling Water, and Non-contact industrial process waters separate from the Sanitary Sewage of the estate or premises. Groundwater, storm water, surface water, roof and surface runoff, uncontaminated Cooling Water, Non-contact Cooling Water, non-contact industrial process waters, and waters from any lake, swamp, pond, or swimming pool shall not be discharged to a Sanitary Sewer, except:

(a) as authorized in 360 CMR 10.023(1) and (2);

(b) swimming pool water may be discharged when there is no reasonable alternative and upon approval by the Authority, which will not be given when a receiving sewer has insufficient capacity to handle the discharge; and

(c) Inflow to a Municipal Sewer or the Authority Sewerage System is prohibited except in those areas served only by a Combined Sewer. Where the Municipality provides only a Combined Sewer, separate Storm Sewer and Sanitary Sewer connections to the Municipality's Combined Sewer shall be constructed in accordance with any permit issued by the Authority.

(3) Pretreatment Requirement. Every Person who directly or indirectly discharges Wastewater to the Authority Sewerage System shall provide the Pretreatment necessary to ensure that the discharge complies with 360 CMR 10.000. All Pretreatment equipment shall be properly installed, maintained, and operated by the Person at its expense.

(4) Pretreatment Operator's License. The individual responsible for operating a pretreatment system that discharges directly or indirectly to the Authority Sewerage System shall possess the proper operator's license(s) as required by law, including 257 CMR 2.00: Certification of Operators of Wastewater Treatment Facilities.

(5) PEP Sewer Connection and Extension Permit. No Person shall connect to a Municipal Sewer or an Authority Sewer, or construct, effect, modify, or maintain a Sewer extension or connection, without a sewer system connection or extension permit issued by DEP pursuant to M.G.L. c. 21, § 43, and 314 CMR 7.00: Sewer System Extension and Connection Permit Program where such a permit is required. A Person who must obtain a sewer system connection or extension permit from DEP for a connection or extension that will include a discharge industrial waste within the Authority Sewerage District shall submit a copy of the DEP permit application to the Authority, and to the appropriate Municipality, when it submits the application to DEP.

(6) Bypass. No Person shall cause or allow a Bypass, except as allowed by 40 CFR 403.17.

(7) Notification of Changed Discharge. Every Person who directly or indirectly discharges industrial waste to the Authority Sewerage system shall notify the Authority in advance of any substantial change in the volume or character of pollutants in his discharge, including the listed or characteristic hazardous wastes for which the Person has submitted initial notification under 40 CFR 403.12(p).
