Regulation of discharges to the municipal separate storm sewer system (MS4) is necessary for the protection of the City's water bodies and groundwater, and to safeguard the public health, safety, welfare and the environment. Increased and contaminated stormwater runoff associated with developed land uses and the accompanying increase in impervious surface are major cause of:
Therefore, this chapter establishes clearing, grading and stormwater management standards for the final conditions that result from development and redevelopment projects to minimize adverse impacts offsite and downstream which would be borne by abutters, City residents and the general public. Regulation of clearing and grading activities will also protect and preserve existing healthy native trees and vegetation, and minimize fragmentation of wildlife habitat.
Further, the chapter prohibits nonstormwater discharges to municipal storm drains that could contribute contaminants and additional flow to the City drain system.
The objectives of this chapter are:
To require enhanced and low impact development practices that control the flow of stormwater from new and redeveloped sites into the City's storm drainage system in order to prevent flooding and erosion;
To prohibit illicit connections and unauthorized discharges to the City's MS4;
To require removal of all such illicit connections;
To require practices that eliminate soil erosion and sedimentation and control the volume and rate of stormwater runoff resulting from land disturbance activities;
To promote infiltration and the recharge of groundwater;
To promote preservation of existing healthy trees and vegetation;
To ensure that soil erosion and sedimentation and stormwater runoff control practices are incorporated into the site planning and design process and are implemented and maintained;
To require practices to control waste such as discarded building materials, concrete truck washout, chemicals, vehicle and equipment fluids, litter, and sanitary waste at the construction site that may cause adverse impacts to water quality;
To protect groundwater and surface water and wetland resource areas from degradation;
To prevent pollutants from entering the City's municipal separate storm sewer system (MS4) and to minimize discharge of pollutants from the MS4;
To ensure adequate long-term operation and maintenance of structural stormwater best management practices so that they work as designed;
To comply with state and federal statutes and regulations relating to stormwater discharges; and
To establish the City's legal authority to ensure compliance with the provisions of this chapter through permitting, inspection, monitoring, and enforcement.

Design parameters. Stormwater design shall be evaluated using Standards 2 through 10 of the DEP Massachusetts Stormwater Management Standards using the applicable Best Management Practices (BMP) Guidelines, set forth in the latest editions of the Massachusetts Stormwater Handbook, Volumes 1 to 3 ("Guidelines"), and its companion book, Erosion and Sediment Control for Urban and Suburban Areas, Massachusetts Department of Environmental Protection ("Handbook"). Rainfall data shall be obtained from the most recent accepted data available, but shall not be less than those design storms referenced in the "Atlas of Precipitation Extremes for the Northeastern United States and Southeastern Canada" (http://www.nrcc.cornell.edu/reports/RR 93-5.pdf). For Standard 4 of the DEP Massachusetts Stormwater Management Standards, applicants shall use a water quality volume of one inch of runoff times the amount of total impervious area of the construction phase and post-development condition on all projects and all stormwater management systems on new and redeveloped sites shall be designed to either:
Retain the first one inch of runoff from all impervious surfaces on site; or
Provide the level of pollutant removal equal to or greater than the level of pollutant removal provided through the use of biofiltration on the first one inch of runoff from all impervious surfaces on site. This standard shall be met through a combination of practices designed to retain runoff on site (environmentally sensitive site design, low-impact development techniques) where technically feasible, and stormwater BMPs designed to treat the remainder of runoff that cannot be retained on site due to site constraints. The level of pollutant removal from BMPs shall be calculated consistent with EPA Region 1's BMP Performance Extrapolation Tool. (Note: The BMP Performance Extrapolation tool, instructions and background can be found here: http://www.epa.gov/region1/npdes/stormwater/.) BMPs shall be optimized for nitrogen and phosphorous removal.
Redevelopment of previously developed sites shall meet the applicable guidelines and handbook standards, principally Standards 4, 5, 6, 8 and 9, to the maximum extent practicable. However, if it is not practicable to meet all standards, new (retrofitted or expanded) stormwater management shall, at a minimum, be designed to improve existing conditions.
The post-development peak discharge rate is equal or less than the pre-development rate from the two-year, ten-year, twenty-five-year, and one-hundred-year twenty-four-hour storms. If increased off-site flooding will result from peak discharges from the one-hundred-year twenty-four-hour storm, BMPs must be provided to attenuate these discharges.
The annual recharge from the post-development site shall approximate the annual recharge rate from pre-development conditions based on soil type. Post-development infiltration volume of precipitation into the ground shall be at least as much as infiltration pre-development.
At sites with Class D soil hydrologic groups, or that have bedrock at or near the surface, Standard No. 3 of the MA Stormwater Management Standards may be waived provided that a preponderance of evidence clearly supports that infiltration volumes of 0.10 inch of runoff multiplied by the amount of impervious surfaces is unobtainable. It is the responsibility of the applicant to provide infiltration rates throughout the soil profile (A and B horizons, and C layer), and provide, to the best extent practicable, BMPs that promote infiltration.
The system shall remove 80% of the average annual post-construction load of total suspended solids (TSS).
The developer is strongly encouraged to utilize environmentally sensitive site design techniques, including, but not limited to, low-impact development (LID) and nonstructural best management practices (BMPs) whenever possible, to reduce costs and to minimize disturbance to the site.

A mounding analysis shall be provided in areas where vertical separation from the bottom of the exfiltration system to the estimated seasonal high groundwater table is less than four feet and the recharge system is proposed to attenuate the 10 year of higher twenty-four-hour storm event. In the event a mounding analysis is to be performed, the Hantush Method, or another equivalent method, is to be used. Standard septic system percolation testing is not an acceptable infiltration test.

The applicable authority may suspend municipal storm drain system access to any person or property without prior written notice when such suspension is necessary to stop an actual or threatened discharge of pollutants that presents imminent risk of harm to the public health, safety, welfare or the environment. In the event any person fails to comply with an emergency suspension order, the applicable authority may take all reasonable steps to prevent or minimize harm to the public health, safety, welfare or the environment.
A person commits an offense if the person reinstates water service, sanitary sewer service, and/or MS4 access to premises terminated pursuant to this chapter, without the prior written approval of the applicable authority.
Every person owning property through which a watercourse passes, or such person's lessee, shall keep and maintain that part of the watercourse within the property free of trash, debris, and other obstacles that would pollute, contaminate, or significantly retard the flow of water through the watercourse. In addition, the owner or lessee shall maintain existing privately owned structures within or adjacent to a watercourse so that such structures will not become a hazard to the use, function, or physical integrity of the watercourse.
Failure by the property owner to maintain the watercourse does not constitute an obligation on the part of the City to assume this responsibility.
Notwithstanding other requirements of local, state or federal law, as soon as a person responsible for a facility or operation, or responsible for emergency response for a facility or operation, has information of or suspects a release of materials at that facility or operation resulting in or which may result in discharge of pollutants to the municipal drainage system or wetland resource areas, the person shall take all necessary steps to ensure containment and cleanup of the release. In the event of a release of oil or hazardous materials, the person shall immediately notify the municipal fire and police departments. In the event of a release of nonhazardous material, the reporting person shall notify the applicable authority no later than the next business day. The reporting person shall provide to the applicable authority written confirmation of all telephone, facsimile or in-person notifications within three business days thereafter.

The applicable authority or its designated agent shall make inspections as hereinafter required and shall either approve that portion of the work completed or shall notify the permittee wherein the work fails to comply with the permit as approved. The applicant shall pay all fees associated with inspection services. The City shall select a qualified inspector. The permit and associated plans for grading, stripping, excavating, and filling work, bearing the signature of approval of the applicable authority, shall be maintained at the site during the progress of the work. In order to obtain inspections, the permittee shall notify the applicable authority at least two working days before each of the following events:
Erosion and sediment control measures are in place and stabilized;
Site clearing has been substantially completed;
Rough grading has been substantially completed;
Final grading has been substantially completed;
Close of the construction season; and
Final landscaping (permanent stabilization) and project final completion.
Permittee inspections. The permittee or his/her agent shall conduct and document inspections of all control measures no less than weekly or as specified in the permit, and prior to and following storms that exceed the statistical two-year, twenty-four-hour event. The purpose of such inspections will be to determine the overall effectiveness of the control plan, and the need for maintenance or additional control measures. The permittee or his/her agent shall submit monthly reports to the applicable authority or designated agent in a format approved by the applicable authority.
The applicable authority may require the permittee to post before the start of land disturbance or construction activity a surety bond, irrevocable letter of credit, cash, or other acceptable security. The form of the performance guarantee shall be approved by the City Solicitor, and be in an amount deemed sufficient by the applicable authority to ensure that the work will be completed in accordance with the permit. If the project is phased, the applicable authority may release part of the performance guarantee as each phase is completed in compliance with the permit but the performance guarantee may not be fully released until the applicable authority has received the final inspection report as required by Section 26-13 and issued a certificate of completion.

Said order shall further advise that, should the violator or property owner fail to abate or perform remediation within the specified deadline, the City may, at its option, undertake such work, and the property owner shall reimburse the City's expenses.
Within 30 days after completing all measures necessary to abate the violation or to perform remediation, the violator and the property owner shall be notified of the costs incurred by the City, including administrative costs. The violator or property owner may file a written protest objecting to the amount or basis of costs with the applicable authority within 30 days of receipt of the notification of the costs incurred. If the amount due is not received by the expiration of the time in which to file a protest or within 30 days following a decision of the applicable authority affirming or reducing the costs, or from a final decision of a court of competent jurisdiction, the costs shall become a special assessment against the property owner and shall constitute a lien on the owner's property for the amount of said costs. Interest shall begin to accrue on any unpaid costs at the statutory rate provided in MGL c. 59, § 57, after the 31st day at which the costs first become due.
