Massachusetts Department of Environmental Protection
Bureau of Resource Protection - Wetlands Program
Checklist for Stormwater Report
A. Introduction
Important: When
filling out forms
on the computer,
use only the tab
key to move your cursor - do not
use the return
key.
A Stormwater Report must be submitted with the Notice of Intent permit application to document
compliance with the Stormwater Management Standards. The following checklist is NOT a substitute for
the Stormwater Report (which should provide more substantive and detailed information) but is offered
here as a tool to help the applicant organize their Stormwater Management documentation for their
Report and for the reviewer to assess this information in a consistent format. As noted in the Checklist,
the Stormwater Report must contain the engineering computations and supporting information set forth in
Volume 3 of the Massachusetts Stormwater Handbook. The Stormwater Report must be prepared and
certified by a Registered Professional Engineer (RPE) licensed in the Commonwealth.
The Stormwater Report must include:
x The Stormwater Checklist completed and stamped by a Registered Professional Engineer (see
page 2) that certifies that the Stormwater Report contains all required submittals.1 This Checklist
is to be used as the cover for the completed Stormwater Report.
x Applicant/Project Name
x Project Address
x Name of Firm and Registered Professional Engineer that prepared the Report
x Long-Term Pollution Prevention Plan required by Standards 4-6
x Construction Period Pollution Prevention and Erosion and Sedimentation Control Plan required
by Standard 82
x Operation and Maintenance Plan required by Standard 9
In addition to all plans and supporting information, the Stormwater Report must include a brief narrative
describing stormwater management practices, including environmentally sensitive site design and LID
techniques, along with a diagram depicting runoff through the proposed BMP treatment train. Plans are
required to show existing and proposed conditions, identify all wetland resource areas, NRCS soil types,
critical areas, Land Uses with Higher Potential Pollutant Loads (LUHPPL), and any areas on the site
where infiltration rate is greater than 2.4 inches per hour. The Plans shall identify the drainage areas for
both existing and proposed conditions at a scale that enables verification of supporting calculations.
As noted in the Checklist, the Stormwater Management Report shall document compliance with each of
the Stormwater Management Standards as provided in the Massachusetts Stormwater Handbook. The
soils evaluation and calculations shall be done using the methodologies set forth in Volume 3 of the
Massachusetts Stormwater Handbook.
To ensure that the Stormwater Report is complete, applicants are required to fill in the Stormwater Report
Checklist by checking the box to indicate that the specified information has been included in the
Stormwater Report. If any of the information specified in the checklist has not been submitted, the
applicant must provide an explanation. The completed Stormwater Report Checklist and Certification
must be submitted with the Stormwater Report.
1 The Stormwater Report may also include the Illicit Discharge Compliance Statement required by Standard 10. If not included in the Stormwater Report, the Illicit Discharge Compliance Statement must be submitted prior to the discharge of stormwater runoff to
the post-construction best management practices.
2 For some complex projects, it may not be possible to include the Construction Period Erosion and Sedimentation Control Plan in
the Stormwater Report. In that event, the issuing authority has the discretion to issue an Order of Conditions that approves the
project and includes a condition requiring the proponent to submit the Construction Period Erosion and Sedimentation Control Plan
before commencing any land disturbance activity on the site.

Checklist for Stormwater Report
B. Stormwater Checklist and Certification
The following checklist is intended to serve as a guide for applicants as to the elements that ordinarily
need to be addressed in a complete Stormwater Report. The checklist is also intended to provide
conservation commissions and other reviewing authorities with a summary of the components necessary
for a comprehensive Stormwater Report that addresses the ten Stormwater Standards.
Note: Because stormwater requirements vary from project to project, it is possible that a complete
Stormwater Report may not include information on some of the subjects specified in the Checklist. If it is
determined that a specific item does not apply to the project under review, please note that the item is not
applicable (N.A.) and provide the reasons for that determination.
A complete checklist must include the Certification set forth below signed by the Registered Professional
Engineer who prepared the Stormwater Report.
Registered Professional Engineer’s Certification
I have reviewed the Stormwater Report, including the soil evaluation, computations, Long-term Pollution
Prevention Plan, the Construction Period Erosion and Sedimentation Control Plan (if included), the Long-
term Post-Construction Operation and Maintenance Plan, the Illicit Discharge Compliance Statement (if
included) and the plans showing the stormwater management system, and have determined that they
have been prepared in accordance with the requirements of the Stormwater Management Standards as
further elaborated by the Massachusetts Stormwater Handbook. I have also determined that the
information presented in the Stormwater Checklist is accurate and that the information presented in the
Stormwater Report accurately reflects conditions at the site as of the date of this permit application.
Registered Professional Engineer Block and Signature
Signature and Date
Note: This Stormwater Checklist and the Stormwater management discussion provided in Appendix A of the
NOI have not been prepared or stamped by an RPE since this project does not propose any new
impervious areas so no new untreated stormwater discharges will occur. See Narrative in Appendix A
for more detailed information regarding the Stormwater Management Standards.

Standard 4: Water Quality (continued)
N/A The BMP is sized (and calculations provided) based on:
The ½” or 1” Water Quality Volume or
The equivalent flow rate associated with the Water Quality Volume and documentation is
provided showing that the BMP treats the required water quality volume.
N/A The applicant proposes to use proprietary BMPs, and documentation supporting use of proprietary
BMP and proposed TSS removal rate is provided. This documentation may be in the form of the
propriety BMP checklist found in Volume 2, Chapter 4 of the Massachusetts Stormwater Handbook
and submitting copies of the TARP Report, STEP Report, and/or other third party studies verifying
performance of the proprietary BMPs.
N/A A TMDL exists that indicates a need to reduce pollutants other than TSS and documentation showing
that the BMPs selected are consistent with the TMDL is provided.
Standard 5: Land Uses With Higher Potential Pollutant Loads (LUHPPLs)
N/A The NPDES Multi-Sector General Permit covers the land use and the Stormwater Pollution
Prevention Plan (SWPPP) has been included with the Stormwater Report.
N/A The NPDES Multi-Sector General Permit covers the land use and the SWPPP will be submitted prior
to the discharge of stormwater to the post-construction stormwater BMPs.
N/A The NPDES Multi-Sector General Permit does not cover the land use.
N/A LUHPPLs are located at the site and industry specific source control and pollution prevention
measures have been proposed to reduce or eliminate the exposure of LUHPPLs to rain, snow, snow
melt and runoff, and been included in the long term Pollution Prevention Plan.
N/A All exposure has been eliminated.
N/A All exposure has not been eliminated and all BMPs selected are on MassDEP LUHPPL list.
N/A The LUHPPL has the potential to generate runoff with moderate to higher concentrations of oil and
grease (e.g. all parking lots with >1000 vehicle trips per day) and the treatment train includes an oil
grit separator, a filtering bioretention area, a sand filter or equivalent.
Standard 6: Critical Areas
N/A The discharge is near or to a critical area and the treatment train includes only BMPs that MassDEP
has approved for stormwater discharges to or near that particular class of critical area.
N/A Critical areas and BMPs are identified in the Stormwater Report.

Standard 7: Redevelopments and Other Projects Subject to the Standards only to the maximum
extent practicable
The project is subject to the Stormwater Management Standards only to the maximum Extent
Practicable as a:
Limited Project
Small Residential Projects: 5-9 single family houses or 5-9 units in a multi-family development
provided there is no discharge that may potentially affect a critical area.
Small Residential Projects: 2-4 single family houses or 2-4 units in a multi-family development
with a discharge to a critical area
Marina and/or boatyard provided the hull painting, service and maintenance areas are protected
from exposure to rain, snow, snow melt and runoff
Bike Path and/or Foot Path
Redevelopment Project
Redevelopment portion of mix of new and redevelopment.
Certain standards are not fully met (Standard No. 1, 8, 9, and 10 must always be fully met) and an
explanation of why these standards are not met is contained in the Stormwater Report.
N/A The project involves redevelopment and a description of all measures that have been taken to
improve existing conditions is provided in the Stormwater Report. The redevelopment checklist found
in Volume 2 Chapter 3 of the Massachusetts Stormwater Handbook may be used to document that
the proposed stormwater management system (a) complies with Standards 2, 3 and the pretreatment
and structural BMP requirements of Standards 4-6 to the maximum extent practicable and (b)
improves existing conditions.
