No application for approval of a land development activity shall
be reviewed until the appropriate board has received a stormwater
pollution prevention plan (SWPPP) prepared in accordance with the
specifications in this chapter.
All SWPPPs shall provide the following background information
and erosion and sediment controls:
A. Background information about the scope of the project, including
location, type and size of the project;
B. Site map/construction drawing(s) for the project, including a general
location map:
(1) At a minimum, the site map should show the total site area; all improvements;
areas of disturbance; areas that will not be disturbed; existing vegetation;
on-site and adjacent off-site surface water(s); wetlands and drainage
patterns that could be affected by the construction activity; existing
and final slopes; locations of off-site material, waste, borrow or
equipment storage areas; and location(s) of the stormwater discharge(s);
(2) The site map should be at a scale no smaller than one inch equals
100 feet (e.g., one inch equals 500 feet is smaller than one inch
equals 100 feet);
C. Description of the soil(s) present at the site;
D. A construction phasing plan describing the intended sequence of construction
activities, including clearing and grubbing, excavation and grading,
utility and infrastructure installation and any other activity at
the site that results in soil disturbance. Consistent with the New
York Standards and Specifications for Erosion and Sediment Control
(Erosion Control Manual), not more than five acres shall be disturbed
at any one time unless pursuant to an approved SWPPP;
E. A description of the pollution prevention measures that will be used
to control litter, construction chemicals and construction debris
from becoming a pollutant source in stormwater runoff;
F. A description of construction and waste materials expected to be
stored on site, with updates as appropriate, and a description of
controls to reduce pollutants from these materials, including storage
practices to minimize exposure of the materials to stormwater, and
spill prevention and response;
G. Temporary and permanent structural and vegetative measures to be
used for soil stabilization, runoff control and sediment control for
each stage of the project from initial land clearing and grubbing
to project closeout;
H. A site map/construction drawing(s) specifying the location(s), size(s)
and length(s) of each erosion and sediment control practice;
I. Dimensions, material specifications and installation details for
all erosion and sediment control practices, including the siting and
sizing of any temporary sediment basins;
J. Temporary practices that will be converted to permanent control measures;
K. An implementation schedule for staging temporary erosion and sediment
control practices, including the timing of initial placement and duration
that each practice should remain in place;
L. A maintenance schedule to ensure continuous and effective operation
of the erosion and sediment control practice;
M. Name(s) of the receiving water(s);
N. Delineation of SWPPP implementation responsibilities for each part
of the site;
O. A description of structural practices designed to divert flows from
exposed soils, store flows, or otherwise limit runoff and the discharge
of pollutants from exposed areas of the site to the degree attainable;
and
P. Any existing data that describes the stormwater runoff at the site.
The applicant shall provide proof, to the satisfaction of the
Town Engineer, that all other applicable environmental permits have
been acquired for the land development activity prior to approval
of the final stormwater design plan.
