    City of Manchester

    The City of Manchester, New Hampshire has enacted a Storm Water Ordinance in order to protect, maintain, and enhance the environment of the City of Manchester and the public health, safety and the general welfare of the citizens of the city, by controlling discharges of pollutants to the city’s storm water system and to maintain and improve the quality of the receiving waters into which the storm water outfalls flow, including, without limitation, lakes, rivers, streams, ponds, wetlands, and groundwater of the city.  The City of Manchester is the permitting authority for all land disturbing activities and requires the land owner to maintain all on-site stormwater control facilities and all open space areas (e.g. parks or “green” areas) required by the approved stormwater control plan. The City of Manchester will only provide construction permits to projects that establish a plan to manage stormwater runoff occurring during the construction process. The City of Manchester, under the NPDES program, also has the authority to inspect properties for noncompliance and can issue a notice of violation (NOV) for any deficiency or infraction onsite. Property owners are responsible for the maintenance of any stormwater facilities or practices located on the property. The City of Manchester has the authority to inspect stormwater facilities and practices in order to ascertain that they properly maintained and functioning.


    (A) The representative of the Department of Highways shall be permitted to enter and inspect properties and facilities at reasonable times as often as may be necessary to determine compliance with this ordinance.

    (C) The owner or operator shall allow the representative of the Department of Highways ready access to all parts of the premises for the purposes of inspection, sampling, photography, videotaping, examination and copying of any records that are required under the conditions of a National Pollutant Discharge Elimination System Permit to discharge storm water.

This sampling and monitoring equipment shall be maintained at all times in a safe and proper operating condition by the owner or operator at his/her own expense. All devices used to measure flow and quality shall be calibrated to ensure their accuracy.

    (F) Any temporary or permanent obstruction to safe and easy access to the property or facility to be inspected and/or sampled shall be promptly removed by the owner or operator at the written or oral request of the Department of Highways and shall not be replaced.

    Notwithstanding other requirements of law, as soon as any person responsible for a facility, activity or operation, or responsible for emergency response for a facility, activity or operation has information of any known or suspected release of pollutants or non-storm water discharges from that facility or operation which are resulting or may result in illicit discharges or pollutants discharging into storm water, the City of Manchester’s separate storm sewer system, State Waters, or Waters of the U.S., said person shall immediately notify the Department of Highways and take all necessary steps to ensure the discovery, containment, and cleanup of such release so as to minimize the effects of the discharge.
