[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.
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.
SEDIMENT
Mineral or organic soil material that is transported by wind
or water from its origin to another location; the product of erosion
processes.
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.

The Dudley Conservation Commission, as established under MGL
c. 40, § 8C, shall have authority to administer, implement
and enforce this bylaw. Any powers granted to or duties imposed upon
the Conservation Commission may be delegated, in writing, by the Conservation
Commission to its employees or agents or to the Highway Superintendent.
A. Review. The Commission and its agents shall review all applications,
including all waiver requests, for stormwater management permits,
conduct inspections, issue a final permit and conduct any necessary
enforcement action. The applicant shall submit all additional information
requested by the Commission prior to the Commission issuing a decision
on the application.
B. Standards. Projects shall meet the standards of the most recent version
of the Department of Environmental Protection's Massachusetts Stormwater
Handbook, Handbook and any other performance standards set forth in
regulations to be enacted by the Conservation Commission hereunder.
C. Action. The Commission may:
(1) Approve the stormwater management permit application and issue a
permit if it finds that the proposed plan will protect water resources
and meets the objectives and requirements of this bylaw;
(2) Approve the stormwater management permit application and issue a
permit with conditions, modifications or restrictions that the Commission
determines are required to ensure that the project will protect water
resources and meet the objectives and requirements of this bylaw;
(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.
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 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.
