Prohibition of unauthorized discharges. No person shall discharge or cause to be discharged into any stormwater system (municipal or private) watercourses any pollutant or nonstormwater discharge. The allowable nonstormwater discharges (described below) are permitted if deemed not to be a significant contributor of pollutants to the municipal separate storm sewer system.
Allowable nonstormwater discharges: (1)
Discharges which result from residential car washing, or from the washdown of vehicles at retail dealers selling new and used automobiles where no detergents are used and individual residential car washing;
(2)
External building washdown where no detergents are used;
(3)
The use of water to control dust;

(12)
Discharges from foundation or footing drains where flows are not contaminated with process materials such as solvents, or contaminated by contact with soils where spills or leaks of toxic or hazardous materials have occurred;
(13)

The construction, use, maintenance or continued existence of illicit connections to the municipal separate storm sewer system is prohibited. This prohibition expressly includes, without limitation, illicit connections made in the past, regardless of whether the connection was permissible under law or practices applicable or prevailing at the time of connection.
A person is considered to be in violation of this chapter if the person connects a line conveying sewage to the MS4, or allows such a connection to continue and must provide corrective action.
Any drain that has not been documented on plans or approved by a DPW permit, which may be connected to a storm drain system shall be located in the field by the owner or occupant of that property upon receipt of written notice of violation by the building official. Such notice will specify a reasonable time period within which the location of the drain is to be completed and identified as to its use. Results of this investigation are to be documented by a professional engineer or surveyor and filed with the town engineer.
