be managed according to the DEP Stormwater Management Standards as
described in the Handbook, except for the addition of the following
standards as required by the United States Environmental Protection
Agency ("EPA") in the Massachusetts MS4 General Permit, as amended:
A.
New development. Stormwater management systems on new development
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 BPA 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
(e.g., state stormwater handbooks 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; or
(4)
Utilizing off-site mitigation that meets the above standards within
the same USGS HUC12 as the new development site.
B.
Redevelopment (as defined by the Massachusetts MS4 General Permit).
(1)
All redevelopment shall comply with Stormwater Standards 1, 2, 3,
5, 6 and 9 of the Handbook to the maximum extent practicable; and

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. Average annual pollutant removal requirements
are achieved through one of the following methods:
(a)
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
(e.g., state stormwater handbooks and design guidance manuals) may
be used to calculate BMP performance; or
(b)
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
(c)
Meeting a combination of retention and treatment that achieves
the above standards; or
(d)
Utilizing off-site mitigation that meets the above standards
within the same USGS HUC12 as the redevelopment site.
C.
