Editor's Note: See Ch. 160, Stormwater Management.
B. 
Purpose. This regulation sets forth a public review and decision-making process to manage stormwater runoff and post-construction stormwater discharges resulting from the alteration of construction sites or hotspots, as defined herein, located within the NPDES Phase II Regulated Area, or for such sites which drain to the municipal separate storm sewer system within the NPDES Phase II Regulated Area.
A. 
This regulation applies only to the alteration of a construction site or hotspot located within the NPDES Phase II Regulated Area of Boxford, or which drains to the municipal separate storm sewer system within the NPDES Phase II Regulated Area, as defined herein.
B. 
The following exemptions apply to the alteration of a construction site or hotspot:
[Amended 8-5-2021]
(1) 
Normal maintenance and improvement of land in agricultural use as defined by the Wetlands Protection Act regulation 310 CMR 10.04;
(2) 
Emergency activities necessary to protect public health and/or safety, so long as all necessary emergency permits or emergency certifications have been obtained or applied for; and
(3) 
Any work or projects for which all necessary municipal approvals and permits have been issued before the effective date of this chapter.
A. 
Burden of proof. The applicant for a permit shall have the burden of proving by a preponderance of the credible evidence that the work proposed in the permit application will comply with the Massachusetts Stormwater Management Standards and will not have significant or cumulative adverse effect upon the hydrologic response of local watersheds, stormwater runoff rates or volumes, flooding, stream channel erosion, non-point-source pollution, sediment transport and deposition, groundwater recharge, public safety, public and private property, surface water, groundwater resources, drinking water supplies, recreation, aquatic habitats, fish and other aquatic life, property values and other uses of land and water. Failure to provide adequate evidence to the Commission supporting this burden shall be sufficient cause for the Commission to deny a permit or grant a permit with conditions.
[Amended 8-5-2021]
B. 
No person shall perform any activity that alters a construction site or hotspot except as authorized by the Conservation Commission in a stormwater management permit or as otherwise provided in this chapter.
The following definitions shall apply in the interpretation and implementation of this chapter. Additional definitions may be adopted by separate regulation:
ALTERATION
Any activity, which will measurably change the ability of a ground surface area to absorb water or will change existing surface drainage patterns. Examples include, but are not limited to, earthmoving, paving, and modification of existing vegetation.
ABUTTER
The owner of any property any portion of which lies within 500 feet radially from any lot line of the subject property, including owners of land directly opposite on any public or private street or way including any in another municipality or across a body of water. In the case of property that has frontage on a pond, abutters shall include all those properties with frontage on the pond or pond association if in existence.
CONSTRUCTION SITE
Any site where activity is proposed or occurs that involves the alteration of an area of one acre (43,560 square feet) or more during or post-construction, or that will alter less than one acre of land but is part of a larger, common plan of development or sale that will ultimately disturb one acre or more of land. A project with a limit of disturbance shown on a plan encompassing an acre or more is a construction site.
HOTSPOT
Land uses or activities, without regard to square footage, that have the potential for high stormwater runoff pollutant loadings, including, but not limited to, auto fueling facilities, fleet storage yards, municipal and commercial parking lots, road salt storage areas and designated snow disposal areas, long-term staging areas for construction or landscaping operations, and commercial outdoor maintenance, storage or loading areas.
INFEASIBLE
Not technologically possible, or not economically practicable and achievable in light of best industry practices.
[Added 6-17-2021]
MAJORITY VOTE

(h) 
For each predevelopment design point there shall be a corresponding post-development design point.
(i) 
Estimated seasonal high groundwater elevation and infiltration rates in areas proposed for use as stormwater retention, detention, or infiltration measures, shall be determined by a professional engineer, registered sanitarian or certified soil scientist based upon one or more soil observation holes dug in the location of the proposed management measure.
(j) 
Off-site areas shall be assessed based on their "predeveloped condition" for computing the water quality volume (i.e., treatment of only on-site areas is required). However, if an off-site area drains to a proposed BMP, flow from that area must be accounted for in the sizing of a specific practice.
(k) 
Off-site areas should be modeled as "present condition" for peak-flow attenuation requirements.
(l) 
The standard for characterizing predevelopment land use for on-site areas is "good woods." Predevelopment Runoff Curve Numbers by NRCS hydrologic soil group (HSG) shall be:
[1] 
HSG A: 30.
[2] 
HSG B: 55.
[3] 
HSG C: 70.
[4] 
HSG D: 77.
(m) 
The determination of flooding and channel erosion impacts to receiving streams due to land development projects shall be measured at each point of discharge from the development project, and such determination shall include any runoff from the balance of the watershed which also contributes to that point of discharge.
(n) 
Stormwater management systems on new development sites shall be designed to meet an average annual pollutant removal equivalent to 90% of the average annual load of total suspended solids (TSS) related to the total post-construction impervious area on the site and 60% of the average annual load of total phosphorus (TP) related to the total post-construction impervious surface area on the site. Average annual pollutant removal requirements are achieved through one of the following methods:
[1] 
Installing BMPs that meet the pollutant removal percentages based on calculations developed consistent with EPA Region 1’s BMP Accounting and Tracking Tool (2016) or other BMP performance evaluation tool provided by EPA Region 1, where available. If EPA Region 1 tools do not address the planned or installed BMP performance, then any federally or state-approved BMP design guidance or performance standards (see State Stormwater Handbook and design guidance manuals) may be used to calculate BMP performance; or
[2] 
Retaining the volume of runoff equivalent to, or greater than, one inch multiplied by the total post-construction impervious surface area on the new development site; or
[3] 
Meeting a combination of retention and treatment that achieves the above standards.
(o) 
Stormwater management systems on redevelopment sites shall be designed to meet an average annual pollutant removal equivalent to 80% of the average annual post-construction load of total suspended solids (TSS) related to the total post-construction impervious area on the site AND 50% of the average annual load of total phosphorus (TP) related to the total post-construction impervious surface area on the site. Annual pollutant removal requirements are achieved through one of the following methods:
[1] 
Installing BMPs that meet the pollutant removal percentages based on calculations developed consistent with EPA Region 1’s BMP Accounting and Tracking Tool (2016) or other BMP performance evaluation tool provided by EPA Region 1, where available. If EPA Region 1 tools do not address the planned or installed BMP performance, then any federally or state-approved BMP design guidance or performance standards (see State Stormwater Handbook and design guidance manuals) may be used to calculate BMP performance; or
[2] 
Retaining the volume of runoff equivalent to, or greater than, 0.8 inch multiplied by the total post-construction impervious surface area on the redeveloped site; or
[3] 
Meeting a combination of retention and treatment that achieves the above standards; or
[4] 
On redevelopment sites, stormwater management systems may utilize off-site mitigation that meets the above standards within the same USGS HUC12 as the redevelopment site to meet the equivalent retention or pollutant removal requirements.
(p) 
All projects must implement, unless infeasible (see definition), low-impact development (LID) site planning and design strategies in order to reduce the discharge of stormwater from development sites.
(3) 
Operation and management plan. The following minimum requirements apply. At its sole discretion the Commission may relax these requirements for small projects.
(a) 
The name(s) of the owner(s) for all components of the proposed project.
(b)

At a minimum, the applicant shall provide for annual certification documenting the work that has been done over the prior 12 months to properly operate and maintain the stormwater control measures. The certification shall be signed by the person(s) or authorized agent of the person(s) named in the permit as being responsible for ongoing operation and management.
[Amended 6-17-2021; 8-5-2021]
(g) 
Stormwater management easements in recordable form shall be provided by the property owner(s) as necessary to ensure access for facility inspections and maintenance. Stormwater management easements are required for all areas used for off-site stormwater control, unless a waiver is granted by the issuing authority. Easements shall be recorded with the Essex South Registry of Deeds prior to the preactivity meeting.
(h) 
The owner(s) of the stormwater management system must notify the Boxford Conservation Commission of changes in ownership.
(i) 
The operation and maintenance plan shall be recorded with the stormwater management permit (Subsection I).
