[HISTORY: Adopted by the Town Meeting of the Town of Dudley as indicated in article histories. Amendments noted where applicable.]
[Adopted 10-25-2021 by Art. 20]
The purpose of this bylaw is to protect, maintain and enhance the public health, safety, environment and general welfare by establishing minimum requirements and procedures to control the adverse effects of increased post-development stormwater runoff and nonpoint source pollution associated with new development and redevelopment construction activity. The Town of Dudley supports the use of low-impact development (LID) stormwater management practices whenever possible and better site design to minimize stormwater-related impacts within the Town. The LID practices promoted in the most recent version of the Massachusetts Department of Environmental Protection Massachusetts Stormwater Handbook should be considered for use on development and redevelopment projects in the Town.
The following definitions shall apply in the interpretation and implementation of this bylaw:
ABUTTER
The owner(s) of land sharing a common property line with the owner of land that is the subject of an application and the owners of land directly opposite on any public or private street or way, and abutters to the abutters within 300 feet of the property line of land that is the subject of the application as they appear on the most recent applicable tax list, notwithstanding that the land of any such owner is located in another city or town.
AGRICULTURE
The normal maintenance or improvement of land in agricultural or aquacultural use, as defined by the Massachusetts Wetlands Protection Act (MGL c. 131, § 40) and its implementing regulations (310 CMR 10.00 et seq.) and any agricultural activity which is consistent with an approved soil conservation plan prepared or approved by the United States Department of Agriculture (USDA) Natural Resources Conservation Service.
ALTERATION
Any activity that will measurably change the ability of a ground surface area to absorb water or will change existing surface drainage patterns. Alteration may be similarly represented as "alteration of drainage characteristics," and "conducting land-disturbing activities." Such changes include, but are not limited to: change from distributed runoff to confined, discrete discharge; change in the volume of runoff from the area; change in the peak rate of runoff from the area; and change in the recharge to groundwater on the area.
APPLICANT
Any person, as defined below, requesting a stormwater management permit for a proposed land-disturbing activity.
BEST MANAGEMENT PRACTICE (BMP)
Structural, nonstructural and managerial techniques that are recognized to be the most effective and practical means to prevent and/or reduce increases in stormwater volumes and flows, reduce point source and nonpoint source pollution, and promote stormwater quality and protection of the environment. "Structural" BMPs are devices that are engineered and constructed to provide temporary storage and treatment of stormwater runoff. "Nonstructural" BMPs use natural measures to reduce pollution levels, do not require extensive construction efforts, and/or promote pollutant reduction by eliminating the pollutant source.
CLEARING
Any activity that removes the vegetative surface cover. Clearing activities generally include disturbance or grubbing activity as defined below.
COLD WATER FISHERY
Environmental resources defined by Massachusetts Division of Fisheries and Wildlife as meeting at least one of three criteria:
A. 
Environmental resources determined to contain brook, brown or rainbow trout;
B. 
Environmental resources maintaining a presence of slimy sculpin or longnose sucker; or
C. 
Waters stocked with Atlantic salmon fry or parr.
DEVELOPMENT
The modification of land to accommodate a new use or expansion of use, usually involving construction.
EROSION
The wearing away of the land surface by natural or artificial forces such as wind, water, ice, gravity, or vehicle traffic and the subsequent detachment and transportation of soil particles.
EROSION AND SEDIMENTATION CONTROL PLAN
A document containing narrative, drawings and details developed by a qualified professional engineer (PE), a professional land surveyor (PLS), a registered landscape architect (RLA), or a certified professional in erosion and sedimentation control (CPESC), which includes best management practices or equivalent measures designed to control surface runoff, erosion and sedimentation during pre-construction and construction-related land disturbance activities.
GRUBBING
The act of clearing land surface by digging up roots and stumps.
IMPERVIOUS COVER
Any material or structure on or above the ground that prevents water infiltrating the underlying soil. Impervious cover includes, without limitation, roads, paved parking lots, sidewalks, and rooftops.
LAND-DISTURBING ACTIVITY or LAND DISTURBANCE
Any activity, including clearing and grubbing, that causes a change in the position or location of soil, sand, rock, gravel, or similar earth material.
LOW-IMPACT DEVELOPMENT (LID)
Development that results in minimized alterations of the land for a more sustainable land development pattern. Implementation of LID in the site planning process helps identifies critical natural resources and aids development of appropriate building envelopes to preserve resources. LID also incorporates a range of best management practices (BMPs) that preserve the natural hydrology of the land, minimize impervious areas and preserve vegetation.
MASSACHUSETTS STORMWATER MANAGEMENT POLICY
The policy issued by the Department of Environmental Protection, as amended from time to time, that coordinates the requirements prescribed by state regulations promulgated under the authority of the Massachusetts Wetlands Protection Act, MGL c. 131, § 40, and the Massachusetts Clean Waters Act, MGL c. 21, §§ 23 through 56. The policy addresses stormwater impacts through implementation of performance standards to reduce or prevent pollutants from reaching water bodies and controlling site runoff quantities.
MUNICIPAL STORM DRAIN SYSTEM or MUNICIPAL SEPARATE STORM SEWER SYSTEM (MS4)
The system of conveyances designed or used for collecting or conveying stormwater, including any road with a drainage system, street, gutter, curb, inlet, piped storm drain, pumping facility, retention or detention basin, natural or man-made or altered drainage channel, reservoir, or other drainage structure that together comprise the storm drainage system owned or operated by the Town of Dudley.
NONPOINT SOURCE POLLUTION
Pollution from diffuse sources, as opposed to discrete conveyances, caused by water, including rainfall or snowmelt, moving over or through the ground.
NORMAL MAINTENANCE
Activities that are regularly scheduled to maintain the health and condition of a landscaped area. Examples include removal of weeds or invasive species, pruning, mowing, raking, and other activities that are done at regular intervals within the course of a year.
OPERATION AND MAINTENANCE PLAN
A plan describing the functional, financial, and organizational mechanisms for the ongoing operation and maintenance of a stormwater management system to ensure that it continues to function as designed.
PERSON
An individual, partnership, association, firm, company, trust, corporation, agency, authority, department or political subdivision of the Commonwealth or the federal government, to the extent permitted by law, and any officer, employee, or agent of such person.
POINT SOURCE
Any discernible, confined, and discrete conveyance, including, but not limited to, any pipe, ditch, channel, tunnel, conduit, well, discrete fissure, or container from which pollutants are or may be discharged.
POST-DEVELOPMENT
Those conditions that reasonably may be expected or anticipated to exist after completion of the land development activity on a specific site or parcel of land. "Post-development" also refers to the phase of a new development or redevelopment project after completion, and does not refer to the construction phase of a project.
PRE-DEVELOPMENT
Those conditions that exist at the time that plans for the land development of a site or parcel of land are submitted to the Commission. When phased development or plan approval occurs (preliminary grading, roads and utilities, etc.), the existing conditions at the time prior to the first plan submission shall establish pre-development conditions.
REDEVELOPMENT
Development, rehabilitation, expansion, demolition or phased projects that disturb the ground surface or increase the impervious area on previously developed sites.
RUNOFF
Rainfall, snowmelt, or irrigation water flowing over the ground surface.

SITE
Any lot or parcel of land or area of property where land-disturbing activities are, were, or will be performed.
SOIL
Earth materials, including decomposed organic material, humic materials, sand, rock and gravel.
STABILIZATION
The use, singly or in combination, of mechanical, structural, or vegetative methods to prevent or retard erosion.
STORMWATER
Stormwater runoff, snow melt runoff, and surface water runoff and drainage.
STORMWATER MANAGEMENT PERMIT (SMP)
A permit issued by the Commission, after review of an application, plans, calculations, and other supporting documents, which is designed to protect the environment of the Town of Dudley from the deleterious effects of uncontrolled and untreated stormwater runoff.
STORMWATER MANAGEMENT PLAN
A document containing narrative, drawings and details prepared by a qualified professional engineer (PE), a professional land surveyor (PLS), or a certified professional in erosion and sedimentation control (CPESC), which includes structural and nonstructural best management practices to manage and treat stormwater runoff generated from regulated development activity. A stormwater management plan also includes an operation and maintenance plan describing the maintenance requirements for structural best management practices.
WETLAND RESOURCE AREA
Areas specified in the Massachusetts Wetlands Protection Act, MGL c. 131, § 40, and in Chapter 294, Wetlands Protection, of the Town of Dudley.
A. 
This bylaw is adopted under the authority granted by the Home Rule Amendment of the Massachusetts Constitution and the Home Rule Procedures Act and pursuant to the regulations set forth in the federal Clean Water Act found at 40 CFR 122.34.
B. 
This bylaw applies to any land-disturbing activity in the Town of Dudley as defined in this bylaw. All other land-disturbing activities below the thresholds established below do not require an administrative review but shall employ best management practices to ensure that erosion is controlled and that disturbed soil is contained on site.
C. 
Stormwater management permit. The following land-disturbing activities, whether new development or redevelopment, shall require a stormwater management permit:
(1) 
Excavating, grading, or other activity which disturbs an area of 40,000 or more square feet or a volume of earth resulting in a total quantity equal to or greater than 1,000 cubic yards.
(2) 
Excavating, grading, or other activity which disturbs an area of less than 40,000 square feet if that disturbance is part of a larger development that will disturb 40,000 or more square feet.
D. 
The application for a stormwater management permit shall include the submittal of a stormwater management plan to the Conservation Commission. This stormwater management plan shall contain sufficient information for the Commission to evaluate the environmental impact, effectiveness, and acceptability of the measures proposed by the applicant for reducing adverse impacts from stormwater. This stormwater management plan shall outline BMP implementation at the construction site in accordance with the requirements set forth in Section 2.3.5.c.iii of the MS4 permit. The plan shall be designed to meet, at a minimum, the Massachusetts Stormwater Management Standards as set forth in the DEP Stormwater Management Regulations, Volumes I and II, and as amended from time to time. The Town of Dudley supports the use of nonstructural stormwater management practices, better site design practices or low-impact development (LID) practices, such as reducing impervious cover and the preservation of open space and other natural areas, to the maximum extent practicable.
A. 
Authorized agent. The Conservation Commission, its professional staff or consultants, the Highway Superintendent, and any other authorized agents shall enforce the provisions of this bylaw, issue and prosecute violation notices and enforcement orders, and may pursue all criminal and civil remedies for such violations.
B. 
Orders. Whenever the Conservation Commission or its authorized agent finds that a person has violated a prohibition or failed to meet a requirement of this bylaw, it may order compliance by written notice of violation to the responsible person. Such notice may require, without limitation:
(1) 
The performance of monitoring, analyses, and reporting;
(2) 
That violating practices or operations shall cease and desist;
(3) 
The abatement or remediation of post-development stormwater runoff and nonpoint source pollution and the restoration of any affected property;
(4) 
Payment of a fine to cover administrative and remediation costs; and
(5) 
The implementation of erosion control or stormwater management BMPs.
C. 
If abatement of a violation and/or restoration of affected property is required, the notice shall set forth a deadline within which such remediation or restoration must be completed. The violator shall provide a monthly progress report to the Conservation Commission summarizing the status of the abatement or restoration schedule. In the interim period, the violator may be required to take reasonable and prudent measures to minimize sedimentation and nonpoint source pollution to and from the MS4. Should the violator fail to remediate or restore within a time frame deemed reasonable by the Conservation Commission, may seek a court order authorizing the work to be done by a designated governmental agency or a contractor, and the expense thereof shall be charged to the violator pursuant to MGL c. 40, § 58.
D. 
Within 30 days after abatement of the violation, the violator will be notified of the cost of abatement, including administrative costs. The violator may file a written protest objecting to the amount of the assessment within 30 days of receipt of the notification of costs incurred. If the amount due is not paid within a timely manner, as determined by the decision of the Conservation Commission or its designated agent, or by the expiration of the time in which to file an appeal, the Conservation Commission may impose a municipal charges lien on the property pursuant to MGL c. 40, § 58.
E. 
Appeals. The decisions or orders of the Conservation Commission or its designated agent shall be final. Further relief shall be to a court of competent jurisdiction.
F. 
Civil relief. If a person has violated or continues to violate the provisions of this bylaw, the Conservation Commission may petition a court of competent jurisdiction for a preliminary or permanent injunction restraining the person from activities which would create further violations or compelling the person to perform abatement or remediation of the violation.
G. 
Criminal penalty. Any person that has violated or continues to violate this bylaw shall be fined $300 per offense, the maximum allowable penalty under MGL c. 40, § 21. Each day such violation continues shall constitute a separate offense.
H. 
Noncriminal disposition. In lieu of other enforcement proceedings, penalties, and remedies authorized by this bylaw, the Conservation Commission may elect to use the noncriminal disposition procedure set forth in MGL c. 40, § 21D, and the Town's General Bylaws, §§ 1-5 and 294-9. The penalty shall be $300 per offense, with each day a violation continues constituting a separate offense.
I. 
Violations deemed a public nuisance. In addition to the enforcement processes and penalties provided, any condition caused or permitted to exist in violation of any of the provisions of this bylaw is a threat to public health, safety, and welfare, and is declared and deemed a nuisance, and may be summarily abated or restored at the violator's expense, and/or a civil action to abate, enjoin, or otherwise compel the cessation of such nuisance may be taken. The Board of Health maintains the authority pursuant to MGL c. 111, §§ 122 through 125 to abate violations of this bylaw which are deemed injurious to the public health and therefore a public nuisance.
J. 
Remedies not exclusive. The remedies listed in this bylaw are not exclusive of any other remedies available under any applicable federal, state or local law and it is within the discretion of the Conservation Commission to seek cumulative remedies.
The provisions of the bylaw shall not apply to:

(3) 
Disapprove the stormwater management permit application and deny the permit if it finds that the proposed plan will not protect water resources or fails to meet the objectives and requirements of this bylaw.
D. 
Extensions. A stormwater management permit shall be valid for three years from the date the permit is issued. The Commission may grant extensions for additional one-year periods upon written request for renewal received no later than 30 days prior to expiration of the permit.
Following receipt of a completed application, including all requests for waivers, the Commission shall execute the interdepartmental review process set forth in the regulations established hereunder. The Commission shall not make a decision on the stormwater management permit until it has received comments from the interdepartmental review process or until 20 days have elapsed after receipt of the application materials without submission of comments thereon from other departments.
A. 
Application. A completed application for a stormwater management permit shall be filed with the Commission. No land-disturbing activity shall commence unless a permit has been issued or a waiver and/or exemption has been deemed applicable. The permit application requirements are specified in regulations adopted by the Commission hereunder.
B. 
Public hearing. Unless the applicant agrees to a later date, in writing, the Commission shall hold a public hearing within 30 days of the receipt of a complete application, which shall be inclusive of all requests for waiver(s). Notice of the hearing shall be given by publication in a newspaper of local circulation, by posting in the office of the Town Clerk, and by first-class mail to abutters, all at least seven days prior to the initial public hearing. The Commission shall make the application available for inspection by the public during business hours at the Town Hall. The Commission shall take final action within 21 days from the close of the public hearing unless such time is extended by written agreement between the applicant and the Commission.
C. 
Combined public hearing. In an appropriate case, the Commission may combine its hearing under this bylaw with the hearing conducted under the Wetlands Protection Act (MGL c. 131, § 40) and regulations promulgated thereunder (310 CMR 10.00 et seq.), and the Dudley Wetlands Protection Bylaw, Chapter 294 of the Town Code. The times lines for action by the Conservation Commission under this bylaw do not alter the time lines applicable to permit applications under the Wetlands Protection Act, MGL c. 131, § 40, and regulations promulgated thereunder, 310 CMR 10.00 et seq., and the Dudley Wetlands Protection Bylaw.
A. 
An operation and maintenance plan (O&M plan) is required at the time of application for all projects subject to a stormwater management permit. The maintenance plan shall be designed to ensure compliance with the permit and this bylaw, and that the Massachusetts Surface Water Quality Standards (314 CMR 4.00) are met in all seasons and throughout the life of the system. The Commission shall make the final decision on what maintenance option is appropriate in a given situation. The Commission will consider natural features, proximity of site to water bodies and wetland resource areas, extent of impervious surfaces, size of the site, the types of stormwater management structures, and potential need for ongoing maintenance activities. The operation and maintenance plan activities shall be an ongoing requirement.
B. 
Requirements for the content of the O&M plan and its implementation are specified in stormwater management rules and regulations associated with this bylaw.
Upon the completion of the activities allowed under a stormwater management permit, the applicant shall notify the Commission and request a final inspection and certificate of completion. The applicant shall submit an as-built plan prepared by a professional land surveyor or registered professional engineer along with certification from a registered professional engineer that all construction has been done in accordance with the approved stormwater management plan. If the Conservation Commission determines that all work has been completed in compliance with the approved stormwater management permit, the Conservation Commission shall issue a written certificate of completion to the applicant.
The Conservation Commission may adopt and periodically amend rules and regulations relating to the procedures and administration of this stormwater management bylaw, by majority vote of the Commission, after conducting a public hearing to receive comments. Such hearing date shall be advertised in a newspaper of local circulation at least seven days prior to the hearing date. Failure by the Conservation Commission to promulgate such rules and regulations or a legal declaration of their invalidity by a court of law shall not act to suspend or invalidate the effect of this bylaw.
Pursuant to MGL c. 44, § 53G 1/2, the Commission may require the applicant to post a surety bond, cash, or other acceptable security before the start of any land-disturbing activity. The form of the bond/surety shall be approved by Town Counsel and be in an amount deemed sufficient by the Commission to insure that the work will be completed in accordance with the permit. Any performance bond or certificate of guarantee shall be executed and maintained by a financial institution, surety, or guaranty company qualified to do business in the Commonwealth.
Filing an application for a stormwater management permit grants the Commission, or its agent, permission to enter the site of the land-disturbing activity, as permitted by law, to verify the information in the application and to inspect for compliance with permit conditions.
A. 
The Commission, by regulation, shall promulgate a fee schedule for stormwater management permit applications and requests for certificates of completion. The fee schedule shall be reasonably related to the costs of processing, reviewing and acting upon such application and/or request. The fee specified in such a fee schedule shall be made payable to the Town of Dudley and shall accompany the permit application or request for certificate of completion. The Commission may require an additional fee for review of any change in or alteration from an approved permit. Said fee shall be paid into a special account set up by the Town Treasurer and may be expended by the Commission for the purpose allocated without further appropriation in accordance with the provisions of MGL c. 44, § 53E 1/2.
B. 
Pursuant to MGL c. 44, § 53G, and regulations promulgated by the Commission, the Commission may impose reasonable fees for the purpose of securing outside consultants, including engineers or other experts, in order to aid in the review of proposed projects. Such funds shall be deposited with the Town Treasurer, who shall create an account specifically for this purpose. Additional consultant fees may be requested where the requisite review is more expensive than originally calculated or where new information requires additional consultant services.
A decision by the Conservation Commission made under this bylaw shall be reviewable by a court of competent jurisdiction.
The provisions of this bylaw are hereby declared to be severable. If any provision, clause, sentence, or paragraph of this bylaw or the application thereof to any person, establishment, or circumstances shall be held invalid, such invalidity shall not affect the other provisions or application of this bylaw.
The standards set forth herein and promulgated pursuant to this bylaw are minimum standards. This bylaw does not intend nor imply that compliance by any person will ensure that there will be no erosion nor unauthorized discharge of pollutants into waters of the Commonwealth caused by said person.
