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 Part 2.
A.
All SWPPPs shall provide the following background information and
erosion and sediment controls:
(1)
Background information about the scope of the project, including
location, type and size of project.
(2)
Site map/construction drawing(s) for the project shall be at a scale
no smaller than one inch equals 100 feet and include a general location
map. 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
discharges(s);
(3)
Description of the soil(s) present at the site;
(4)
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.
(5)
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;
(6)
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.
(7)
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 close-out;
(8)
A site map/construction drawing(s) specifying the location(s), size(s)
and length(s) of each erosion and sediment control practice;
(9)
Dimensions, material specifications and installation details for
all erosion and sediment control practices, including the siting and
sizing of any temporary sediment basins;
(10)
Temporary practices that will be converted to permanent control
measures;
(11)
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;
(12)
Maintenance schedule to ensure continuous and effective operation
of the erosion and sediment control practice;
(13)
Name(s) of the receiving water(s);
(14)
Delineation of SWPPP implementation responsibilities for each
part of the site;
(15)
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
(16)
Any existing data that describes the stormwater runoff at the
site.
B.
Land development activities as defined in § 143-23 of this Part 2 and meeting Condition A, B or C below shall also include water quantity and water quality controls (post-construction stormwater runoff controls) as set forth in § 143-27C below as applicable:
(1)
Condition A. Stormwater runoff from land development activities discharging
a pollutant of concern to either an impaired water identified on the
Department's 303(d) list of impaired waters or a total maximum
daily load (TMDL) designated watershed for which pollutants in stormwater
have been identified as a source of the impairment.
(2)
Condition B. Stormwater runoff from land development activities disturbing
five or more acres.
(3)
Condition C. Stormwater runoff from land development activity disturbing
between one and five acres of land during the course of the project,
exclusive of the construction of single-family residences and construction
activities at agricultural properties.
C.
SWPPP Requirements for above Conditions A, B and C:
(2)
Description of each post-construction stormwater management practice;
(3)
Site map/construction drawing(s) showing the specific location(s)
and size(s) of each post-construction stormwater management practice;
(4)
Hydrologic and hydraulic analysis for all structural components of
the stormwater management system for the applicable design storms;
(5)
Comparison of post-development stormwater runoff conditions with
predevelopment conditions;
(6)
Dimensions, material specifications and installation details for
each post-construction stormwater management practice;
(7)
Maintenance schedule to ensure continuous and effective operation
of each post-construction stormwater management practice.
(8)
Maintenance easements to ensure access to all stormwater management
practices at the site for the purpose of inspection and repair. Easements
shall be recorded on the plan and shall remain in effect with transfer
of title to the property.
(10)
For Condition A, the SWPPP shall be prepared by a landscape
architect, certified professional or professional engineer and must
be signed by the professional preparing the plan, who shall certify
that the design of all stormwater management practices meets the requirements
in this Part 2.
The applicant shall assure that all other applicable environmental
permits have been or will be acquired for the land development activity
prior to approval of the final stormwater design plan.
A.
Each contractor and subcontractor identified in the SWPPP who will
be involved in soil disturbance and/or stormwater management practice
installation shall sign and date a copy of the following certification
statement before undertaking any land development activity: "I certify
under penalty of law that I understand and agree to comply with the
terms and conditions of the Stormwater Pollution Prevention Plan.
I also understand that it is unlawful for any person to cause or contribute
to a violation of water quality standards."
B.
The certification must include the name and title of the person providing
the signature, address and telephone number of the contracting firm;
the address (or other identifying description) of the site; and the
date the certification is made.
C.
The certification statement(s) shall become part of the SWPPP for
the land development activity.
A copy of the SWPPP shall be retained at the site of the land
development activity during construction from the date of initiation
of construction activities to the date of final stabilization.
