A. 
Every user who directly or indirectly discharges wastewater to the City's wastewater systems shall comply with the strictest of the following discharge limits applicable to the discharge: the National Pretreatment Standards, NPDES Permit conditions, state limits, MWRA local or permit limits, limits contained in these wastewater regulations, and limits in a permit or order issued under these wastewater regulations. If a national categorical pretreatment standard includes a limit in addition to a daily maximum limit (e.g., thirty-day, monthly, weekly, four-day, loading, or production-based limit), that limit must also be met.
B. 
It shall be unlawful to discharge wastewater to any natural outlet within the City of Framingham, or in any area under the jurisdiction of said City, any sewage or other polluted waters.
No user shall achieve, or attempt to achieve, compliance with these wastewater regulations by diluting a discharge instead of using proper pretreatment. The increased use of process water in place of proper treatment shall be considered dilution and is prohibited by these wastewater regulations.
A. 
When required by the City or the MWRA, a user shall install suitable control or measuring devices together with manholes, chambers, meters, and other appurtenances in its building sewer(s) to facilitate discharge observation, monitoring, sampling and measurement.

C. 
All meters and other measuring devices shall be approved by the City prior to installation and use. All meters and measuring devices shall be calibrated by the owner so as to ensure accurate measurement. The facilities shall be constructed in accordance with all applicable construction standards. Construction shall be completed in compliance with a time schedule established by the City and the MWRA.
D. 
All records from meters, measuring devices and samplers shall be kept for at least five years and furnished to the City and the MWRA upon request. During construction and after installation, the City shall have the right to inspect the facilities in accordance with Article VIII hereof.
A. 
All measurements, tests and analyses of the characteristics of water and wastes required to conform to these wastewater regulations shall be performed in accordance with the most recent edition of Standard Methods, unless otherwise authorized or required by the City, MWRA, EPA or DEP.
B. 
Sample analysis required by these wastewater regulations or any permit issued thereunder shall be performed by an independent laboratory currently certified by the DEP for the parameters being analyzed. The use of a laboratory with provisional DEP certification is prohibited.
C. 
Samples analyzed shall be collected at locations designated by the City or the MWRA and by methods acceptable to, and at a frequency determined by the City and the MWRA. The City or the MWRA will stipulate whether a composite or grab sample(s) should be taken and whether composite samples will be time or flow weighted.
D. 
The City or the MWRA may require an applicant to submit a complete data package, including chain of custody records, raw data, and quality assurance/quality control related results, with a report required by the City or the MWRA. The City may require that discharge monitoring reports be submitted on paper copy, computer diskette, or by electronic means.
All limitations imposed by these wastewater regulations shall be applied at the end of the pretreatment process line, or at the end of the process line if there is no pretreatment. The owner or user shall not introduce a pollutant into a waste stream after the compliance measurement location.
Every user who directly or indirectly discharges waters or waste to the City's wastewater system shall notify the City, in writing, in advance of:
A. 
Any substantial change in the volume or characteristics of the pollutants in the discharge; and
B. 
Any change in the location of the discharge to a different connection.
A. 
Users shall notify the DPW by telephone and electronic mail immediately upon discharging water or wastes in violation of these wastewater regulations or their other permits and of any upset, slug load, or spill that may reasonably be expected to discharge to the wastewater systems.
B. 
Each notification shall be followed within 15 days of the date of occurrence by a detailed written statement addressed to the DPW describing the causes of the discharge and the measures being taken to prevent a recurrence. Such notification will not relieve users of liability for any expense, loss or damage to the City wastewater systems, to the MWRA wastewater system, or for any fines imposed on the City due to such discharge.
C. 
In the case where a discharge to the wastewater system violates these wastewater regulations, any conditions of approval hereunder, or any other permit, the user shall also notify the Director of the MWRA's Sewerage Division immediately, by telephone. Such notification shall be followed within 15 days of the date of occurrence by a detailed written statement delivered to the MWRA.
Each user shall provide reasonable and appropriate protection from any discharge, including accidental discharges, in violation of these wastewater regulations.
