2.0 Stormwater Management Objectives
2.1 Drainage Facilities
The drainage system for this project will consist of a driveway-side French Drain,
and is designed to store and recharge stormwater runoff. The Big Bing Subdivision
Plans,prepared by Fox Land Surveyors, provides the specific details of the proposed
development activities at the site, and is provided in Appendix B.
2.2 Grading
Site grading has been designed to convey stormwater runoff to the proposed
drainage facilities and to minimize/prevent any amount that might flow to adjoining
properties. The runoff from disturbed areas is intended to be directed to the on-site
drainage collection system.

3.0 Pre-Development Conditions Analysis
3.1 Site Topography
The site slopes primarily to the northwest to southeast. The elevation range is
approximately 56-82 feet above mean sea level. A negligible amount off-site runoff
enters the subject parcel in both the pre, and post-development conditions. Existing
elevations and contours are depicted on the Subdivision Plans provided in Appendix B.
The surrounding topography is depicted in the USGS Quad Map, in section 1,Figure 2.
3.2 Existing Land Use
The site currently contains a residence and is largely wooded. The property is
zoned both Agricultural Conservation(AC)and Residence(A-1).
3.3 Soil Characteristics
The Soil Survey of Suffolk County,New York,presents a complete description,
mapping and characterization of soil types found in Suffolk County. This Soil Survey
recognizes the project site as being located in an area characterized by six(6) soil types;
Haven loam, 0 to 2 percent slopes,Riverhead sandy loam, 0 to 3 percent slopes,
Plymouth loamy sand, 3 to 8 percent slopes,Plymouth loamy sand, 8 to 15 percent
slopes,Riverhead sandy loam, 3 to 8 percent slopes and Beach sand. The soil type
distribution is shown below in Table 1.
Soil Type Distribution

Table 1 —Soil Type Distribution
The characteristics of the majority of the identified soil types,are summarized in
the Soil Survey as follows:
3-1
Big Bing Subdivision
Stormwater Pollution Prevention Plan
The Haven series consists of deep, well-drained, medium—textured soils that
formed in a loamy or silty mantle over stratified coarse sand and gravel. These
soils are present throughout the county, but most areas are on outwash plains
between the two terminal moraines. Haven soils have high to moderate available
moisture capacity. Reaction is strongly acid to very strongly acid throughout.
Natural fertility is low. The response of crops to lime and fertilizer is good.
Internal drainage is good. Permeability is moderate in the surface layer and
subsoil and rapid or very rapid in the substratum. The root zone is 25 to 35
inches thick. The soil type HaA, has a profile described as representative of the
series. It is mostly nearly level and generally is on outwash plains.
The Riverhead series consists of deep, well-drained, moderately coarse textured
soils that formed in a mantle of sandy loam or fine, sandy loam over thick layers
of coarse sand and gravel. Riverhead soils have moderate to high available
moisture capacity. Internal drainage is good. Permeability is moderately rapid
in the surface layer and in the subsoil, and very rapid in the substratum. The soil
type RdA, has the profile described as representative of the series. It generally is
on outwash plains, and the areas are large and uniform.
The Plymouth series consists of deep, excessively drained, coarse textured soils
that formed in a mantle of loamy sand or sand over thick layers of stratified
coarse sand and gravel. Plymouth soils have low to very low moisture capacity.
Natural fertility is low. The response of crops to lime and fertilizer is fair. The
root zone is confined mainly to the upper 25 to 35 inches. Internal drainage is
good. Permeability is rapid in all of these soils except in those of the silty
substratum phase. The soil type PIA, is on outwash plains south of the
Ronkonkoma moraine. It is also on flat hilltops and in drainageways on moraine
deposits. The areas generally are nearly level, but they are somewhat undulating
in some places. The hazard for erosion is only slight.
The Hydrologic Soil Groups for soil types present are A and B. Over the vast
majority of the project area, the permeability is excellent in the sandy substratum,where
the transfer to groundwater will ultimately take place. According to the Soil Survey of
Suffolk County,the average saturated hydraulic conductivity (KKsat) of the soils is approx.
100.2 [t/sec, or 14.2 in/hr,which has been used for the purpose of storm event modeling
in section 5.0.
3.4 Stormwater Runoff Characteristics
The soil horizon encountered at the subject property exhibits a moderate range of
available moisture capacities and permeability rates, and has excellent drainage allowing
adequate infiltration of stormwater over the project's pervious area. Runoff originates
over the entire project site in localized tributary areas and moves to designated low-points
once surface/soil saturation has been established. The site currently contains no

discernable amount of impervious surfaces within the tributary and proposed area of
disturbance.
The New York Guidelines for Urban Erosion and Sediment Control, Soil
Conservation Society formula for estimating site runoff based on certain criteria(SCS
Runoff Curve Number Method) is;
_ [P — (0.2S)]2

Where,
Q=runoff(in.)
P=rainfall (in.)
S=potential maximum retention after runoff begins (in.),
S, _ 1000 _10
CN and,
CN= SCS Runoff Curve Number
Runoff rates based on pre-construction site conditions have been calculated for a
1-year, 10-year and 100-year storm event, and are shown below. The site contains
exclusively Hydrological Soil Groups A and B. The pre-construction site conditions, for
the purposes of this calculation, are considered to be vegetated with meadow. This then
yields a CN=43, making S = 13.26.
1-Year Storm (P=2.80): [2.80 — 0.20(13.26)]2

3.5 Groundwater
The depth to groundwater is approximately 58 feet below the surface.
Groundwater flow is in an northerly direction,toward the Long Island Sound.
Groundwater was not encountered in the test hole by others, and is assumed to be at
approximate elevation 9, based on the USGS Long Island Groundwater Mapper.
3.6 Receiving Waters
The majority of the regional precipitation and surface runoff percolates into the
present on-site soils. Overland runoff from the site does have the potential to impact a
water body on the NYSDEC List of 303(d) segments of the Construction Permit, GP-0-
20-001. The property lies outside freshwater wetland CheckZones for State regulated
wetland.
3.7 Six-Step Process for Site Planning and Practice Selection Demonstration
This section summarizes the design process for demonstrating compliance with
following the six-step process for planning and practice selection outlined in section 3.6
of the New York Stormwater Design Manual.
Step I-Site Planning: Working through the Site Plan process dictated by the
Town of Brookhaven, early planning and evaluation considered topography, soil
conditions,natural drainage points, vegetated areas, natural drainage patterns, as
well as zoning laws,to develop the optimal layout for this development. These
features can be clearly seen on the Site Plan provided.
Step 2-Determine Water Quality Treatment Volume: The water quality
treatment volume(WQv) is calculated and discussed in chapter 5 of this report.
Step 3-Apply Runoff Reduction Techniques and Standard SMPs with RRv
Capacity (e.g. infiltration practices, bioretention and open channel practices) to
Reduce Total WQv: Since the entire disturbed and tributary area is intended to be
treated with a standard SMP (infiltration practice),the need to further experiment
with combinations of additional SMP's is not required.
Step 4-Determine the Minimum RRvRequired: The minimum required RRv is
defined as the Specified Reduction Factor(S). Runoff reduction has been
achieved by infiltration/groundwater recharge of 100 percent of the post-
development water quality volume to replicate pre-development hydrology.
3-4
Big Bing Subdivision
Stormwater]Pollution Prevention Plan
Step S-Apply Standard Stormwater Management Practices to Address
Remaining Water Quality Volume: Since all water quality requirements have
been met in Step 3,no further SMP application is required.
Step 6-Apply Volume and Peak Rate Control Practices if Still Needed to Meet
Requirements: Peak rate conditions are calculated in chapter 5 and demonstrate
compliance with pre-condition hydrology flow rates,therefore, no further
practices are necessary.

4.0 Construction Plan
4.1 Description of Project and Proposed Construction Activities
The project construction activity includes the clearing, grading, stabilization and
construction of a residential subdivision drive, utilizing a portion of the applicant's
property,along with the associated storm drainage collection system and public utilities
required for sustainability. The site will be accessed via Oregon Road, an existing east-
west route, immediately adjacent to the property. The proposed site configuration and
other site improvements are further depicted on the Site Plan,provided in Appendix B.
The proposed drainage system is designed to provide post-construction water
quantity and quality controls for stormwater runoff. The system exclusively utilizes a
French drain, directing stormwater runoff resulting from both pervious and impervious
surfaces within the project area.
4.2 Temporary Erosion and Sediment Controls
Prior to the onset of construction activities,temporary erosion and 'sediment
controls will be utilized to ensure soil stabilization and protection of exposed areas
throughout the construction period to the maximum extent practicable. An Erosion&
Sediment Control Plan, (sheet ESCP, in Appendix C)has been prepared for the site in
accordance with the NYSDEC Phase II requirements. The plan proposes a silt fence be
installed in the locations shown, in a necessary effort to minimize/prevent sediment from
leaving the project area. Dust and debris resulting,from daily construction activities shall
be controlled by watering, soil compaction, earth moving management, limiting cleared
areas and stockpile management. Inlet protection at all grated inlet structures is to be
provided to trap sediment in stormwater runoff from impervious surfaces. Establishment
of future groundcover will be implemented as rapidly as is practicable to stabilize and
minimize loss of soils after the bulk of the site grading, and excavation activities have
been completed. Any other temporary management practice deemed necessary and
appropriatemay be utilized as required by field conditions during construction to ensure
stormwater runoff is intercepted and contained on site. In all practicality,NYSDEC best
management practices (BMP's) for erosion controls will be followed. A construction
entrance will be utilized and maintained to prevent soil and loose debris from being
tracked onto local roads.
All erosion and sediment controls depicted on the Stormwater Pollution
Prevention Plan will be installed prior to construction activities and will remain until final
stabilization and proposed termination as defined in Part V.A.2 of the General Permit
GP-0-20-001,unless specifically noted.

3. Inspection of erosion controls throughout the construction period with a minimum
frequency of once every seven (7) calendar days. After every rainfall event of
greater than % inch within a 24-hour period, it is recommended that an inspection
also be made. This practice goes above and beyond the requirements of the current
General Permit. Maintain inspection reports on site during construction.
4. Rough grading of the site in accordance with the approved plans. Stockpile topsoil
required for final grading and landscaping as depicted on the plans. Cover
stockpiles as necessary to avoid exposure to erosive elements.
5. Installation of drainage structures and associated piping. Install inlet protection
measures for any drainage structures with grate covers in accordance with the
Erosion & Sediment Control Plan.
6. Pouring and construction of masonry flatwork, curb, etc., if any. Temporary
stabilization shall be completed following backfilling as conditions warrant.
Stabilization may include but not be limited to hydro-seeding,temporary
vegetation and mulching. Continuation of other site improvements may proceed
concurrently with the remaining schedule of operations.
7. Installation of sub-surface utilities. Other approved construction may`continue
concurrently with the remaining schedule of operations.
8. Installation of sub-base for all proposed paved areas, and perform final grading.
Remove all temporary erosion control measures and install permanent vegetation
and landscaping following site stabilization.
9. Installation of pavement.
10. Cleaning of all drainage structures potentially silted due to possible erosion
incurred during the construction process.

4.6 Pollution Prevention Plan
The Erosion& Sediment Control Plan was designed to contain sediments,
pollutants and debris and to prevent them from migrating off the project site by,
implementing sediment barriers and sound construction practices. All sediment
accidentally spilled, dropped,washed or tracked onto public rights-of-way shall be
removed daily. In an effort to reduce possible sediment migration as a result of
stormwater runoff and to improve site cleanliness,the removal of litter and sweeping of
adjacent areas, sidewalks and pavement of site-generated debris shall be conducted. The
site contractor will be responsible for ensuring that storage and stockpiling of materials
and supplies will only take place in designated areas and that erosion control measures
Are implemented to minimize/prevent wind-blown dust and erosion from weather. The
site contractor, once selected,will be responsible for securing,an approved carter for the
removal of construction generated waste from the project site to an approved location for
disposal.
Currently, Big Bing,LLC, is the party responsible for all phases of
implementation of the SWPPP. Contractor certifications will be added to Appendices D
& E, as they are selected.

5.0 Post-Development Conditions Analysis
5.1 Stormwater Runoff Characteristics
Runoff rates based on post-construction site conditions have been calculated for a
1-year,.10-year and 100-year storm event, and are shown below. The site contains
exclusively Hydrological Soil Group A&B. The post-construction site conditions will
result in an estimated 53%impervious surfaces resulting from pavement, and 47%
pervious surfaces including turf,undisturbed vegetated areas and newly landscaped and
seeded areas, as percentages of the disturbed area. The post-construction site conditions,
for the purposes of this calculation, are considered to be residential (2-acre+density)with
the previously stated impervious surface percentage. Considering these components,this
yields an interpolated CN=45,which makes S= 12.22.
The Soil Conservation Society formula for estimating site runoff based on certain
criteria(SCS Runoff Curve Number Method) is;

Stormwater Pollution Prevention Pian
The post-condition results of stormwater runoff for all three storm events, are
increased compared to that of the pre-condition results of Section 3.3. The proposed
drainage system is designed with a static storage capacity in excess to that of an 8-inch,
24-hour storm event,based on the Rational Method.
5.2 Post-construction Stormwater Runoff Conditions
The New York State Stormwater Management Design Manual provides guidance
for a unified approach"to sizing permanent stormwater management practices (SMP's)to
ensure adequate containment and conveyance of stormwater resulting from the proposed
development. The proposed project,upon completion,will yield approximately 1.27
acres of impervious surfaces, and 1.11 acres of pervious surfaces, over the disturbed area.
A negligible amount of runoff will culminate in depressions or runoff the property at its
perimeter. The disturbed area totals approximately 2.38 acres. The percent impervious
surface within the tributary and disturbed area is 53%.
5.3 Water Quality Volume(WQv)
The criteria outlined in the above referenced design manual specifies that SMP's
should be designed to capture and treat 90%of the average annual stormwater runoff
volume,known as the Water Quality Volume(WQv);
PRV A
W QV _ 12
Where,
WQv= water quality volume (acre-feet)
P= 90%Rainfall Event Number= 1.5
Rv= 0.05 +0.009(I),where I is percent impervious cover

(1.5)(0.527)(2.38)
WQv = 12 = 0.157 acre •feet
WQv=6,839 cubic feet
Based on the above calculations, 6,839 cubic feet of site-generated stormwater
runoff must be adequately captured and treated utilizing the NYSDEC accepted SMP's as
described in the manual. The drainage system proposed for this project utilizes a French

groundwater. The drainage system provided on the Subdivision Plan,provided in
Appendix B, indicates a total provided static capacity of 21,677 cubic feet, or 0.498
acre-feet. This,does not include the effects of exfiltration. Recharge(Infiltration)
trenches are considered an acceptable SMP,with RRv capacity, according the Design
Manual,practice I-1.

5.4 Water Quality Volume Pretreatment and Exfiltration
Since the infiltration rate of the onsite soil is greater than 2 in/hr, 100%of WQv
must be provided for in pretreatment. Therefore,total pretreatment is 2*0.157 acre-feet, or
0.314 acre-feet, which is less than the provided total static system capacity of 0.498
acre-feet.
Further,the entire WQv, including pretreatment volume must be exfiltrated
through the floor of the infiltration practices within 48 hours.
T2WQV
A, = =48hours
AF PS
Where,
Tdw=Total Dewatering Time(hrs)
WQv=Water quality Volume=6,839 c.f.
As =Total surface area of infiltration=27,096 s.f.
Ps =Infiltration rate of soil= 1.18 ft/hr
Tdw = (2 096)(6,83
96(9)18) = 0.43 hrs <_ 48 hrs
In summary,the proposed drainage system as designed, adequately complies with
the NYSDEC 90%capture and treatment requirements as outlined in the Stormwater
Design Manual, since the system provides treatment and storage,which exceeds the
calculated Water Quality Volume, WQv.
5.5 Runoff Reduction Volume(RRv)
The criteria outlined in the referenced Design Manual specifies that runoff
reduction shall be achieved by green infrastructure practices such as infiltration,
groundwater recharge, reuse,recycling and evaporation/evapotranspiration of 100%of
the post-development water quality volumes to replicate pre-development hydrology.
Through open space design,preservation of natural areas, such as native
vegetated areas, natural terrain,pre-development hydrology can be preserved, reducing
stormwater runoff and pollutant load. Since 100%of the water quality volume, WQv, is
delegated to the green infrastructure practices of infiltration and groundwater recharge,
no further green infrastructure practice is required.

Storumwater Pollution Prevention Plan
5.6 Stream Channel Protection Volume(Cpv)
The Design Manual requires that stream channels be protected from erosion. This
is accomplished by providing 24-hour extended detention under the post-development
conditions for a 1-year, 24-hour storm event,known as the Channel Protection Volume
(Cpv). The Channel Protection Volume, as computed by SCS TR-20 modeling of the
pre-development condition, is 26 cubic feet above WQv,which makes Cpv=6,865 cubic
feet. This equates to 0.158 acre-feet. The total static storage provide in the system is
27,096 cubic feet, or 0.498 acre-feet.
Storage, and ultimately recharge of the entire Cpv volume is achieved on site.
5.7 Overbank Flood Control(Qp)
The Design Manual requires that Overbank Flood requirements (Qp) be met. This
consists of controlling the peak discharge from the 10-year,post construction storm
event, to 10-year predevelopment conditions. The peak,pre-condition discharge off the
site is 0.26 cfs. There are currently no definitive drainage facilities installed on the
subject property,therefore all runoff not absorbed on-site, currently discharges from the
property. The peak,post-condition discharging form the site, as computed by SCS TR-20
modeling is 0.0 cfs.
Recharge of the entire peak flow rate is achieved on site within the recharge basin,
and the post-development condition is attenuated to less than the pre-development
discharge. Therefore,the post construction condition is at, or reduced to below the pre-
construction state.
5.8 Extreme Flood Control (Qf)
The Design Manual requires that Extreme Flood Control (Qf) be met. This
includes safely passing the 100-year storm event,which is controlling the peak discharge
from the 100-year,post construction storm event, to 100-year predevelopment conditions.
The peak,pre-condition discharging off the site, as computed by SCS TR-20 modeling is
2.65 cfs. The peak,post-condition discharging form the site, as computed by SCS TR-20
modeling is 0.00 cfs.
Recharge of the entire peak flow rate is achieved on site within the recharge basin,
and the post-development condition is attenuated to less than the pre-development
discharge. Therefore,the post construction condition is at, or reduced to below the pre-
construction state..

Hydrologic Soil Group—Suffolk County,New York Big Bing Subdivision
Description
Hydrologic soil groups are based on estimates of runoff potential. Soils are
assigned to one of four groups according to the rate of water infiltration when the
soils are not protected by vegetation, are thoroughly wet, and receive
precipitation from long-duration storms.
The soils in the United States are assigned to four groups(A, B, C, and D)and
three dual classes (A/D,, B/D, and C/D).The groups are defined as follows:
Group A. Soils having a high infiltration rate(low runoff potential)when
thoroughly wet.These consist mainly of deep,well drained to excessively
drained sands or gravelly sands. These soils have a high rate of water
transmission.
Group B. Soils having a moderate infiltration rate when thoroughly wet. These
consist chiefly of moderately deep or deep, moderately well drained or well
drained soils that have moderately fine texture to moderately coarse texture.
These soils have a moderate rate of water transmission.
Group C. Soils having a slow infiltration rate when thoroughly wet.These consist
chiefly of soils having a layer that impedes the downward movement of water or
soils of moderately fine texture or fine texture. These soils have a slow rate of
water transmission.
Group D. Soils having a very slow infiltration rate(high runoff potential)when
thoroughly wet.These consist chiefly of clays that have a high shrink-swell
potential, soils that have a high water table, soils that have a claypan or clay
layer at or near the surface, and soils that are shallow over nearly impervious
material.These soils have a very slow rate of water transmission.
If a soil is assigned to a dual hydrologic group(A/D, B/D, or C/D),the first letter is
for drained areas and the second is for undrained areas. Only the soils that in
their natural condition are in group D are assigned to dual classes.

Description
Saturated hydraulic conductivity(Ksat) refers to the ease with which pores in a
saturated soil transmit water.The estimates are expressed in terms of
micrometers per second. They are based on soil characteristics observed in the
field, particularly structure, porosity, and texture. Saturated hydraulic conductivity
is considered in the design of soil drainage systems and septic tank absorption
fields.
For each soil layer,this attribute is actually recorded as three separate values in
the database.A low value and a high value indicate the range of this attribute for
the soil component.A"representative"value indicates the expected value of this
attribute for the component. For this soil property, only the representative value is
used.
The numeric Ksat values have been grouped according to standard Ksat class
limits. =

a. Preamble to Site Assessment and Inspections
The Following Information To Be Read By All Person's Involved in The Construction of Stormwater Re-
lated Activities:
The Operator agrees to have a qualified inspector)conduct an assessment of the site prior to the commence-
ment of construction and certify in this inspection report that the appropriate erosion and sediment controls
described in'the SWPPP have been adequately installed or implemented to ensure overall preparedness of
the site for the commencement of construction.
Prior to the commencement of construction,the Operator shall certify in this site logbook that the SWPPP
has been prepared in accordance with the State's standards and meets all Federal, State and local erosion
and sediment control requirements., A preconstruction meeting should be held to review all of the SWPPP
requirements with construction personnel.
When construction starts, site inspections shall be conducted by the qualified inspector at least every 7 cal-
endar days.The Operator shall maintain a record of all inspection reports in this site logbook. The site log-
book shall be maintained on site and be made available to the permitting authorities upon request.
Prior to filing the Notice of Termination or the end of permit term,the Operator shall have a qualified in-
spector perform a final site inspection.The qualified inspector shall certify that the site has undergone final
stabilization3 using either vegetative or structural stabilization methods and that all temporary erosion and
sediment controls(such as silt fencing)not needed for long-term erosion control have been removed. In
addition,the Operator must identify and certify that all permanent structures described in the SWPPP have
been constructed and provide the owner(s)with an operation and maintenance plan that ensures the struc-
ture(s)continuously functions as designed.
1 Refer to"Qualified Inspector"inspection requirements in the current SPDES General Permit for Stormwater Discharges
from Construction Activity for complete list of inspection requirements.
2"Commencement of construction"means the initial removal of vegetation and disturbance of soils associated with
clearing,grading or excavating activities or other,construction activities.
3"Final stabilization"means that all soil-disturbing activities at the site have been completed and a uniform,perennial
vegetative cover with a density of eighty(80)percent has been established or equivalent stabilization measures(such as r
the use of mulches or geotextiles)have been employed on all unpaved areas and areas not covered by permanent struc-
tures.

PREFACE
Pursuant to Section 402 of the Clean Water Act ("CWA"), stormwater discharges
from certain construction activities are unlawful unless they are authorized by a National
Pollutant Discharge Elimination System ("NPDES") permit or by a state permit program.
New York administers the approved State Pollutant Discharge Elimination System
(SPDES) program with permits issued in accordance with the New York State
Environmental Conservation Law (ECL) Article IT, Titles 7, 8 and Article 70.
An owner or operator of a construction activity that is eligible for coverage under
this permit must obtain coverage prior to the commencement of construction activity.
Activities that fit the definition of"construction activity', as defined under 40 CFR
122.26(b)(1 4)(x), (15)(i), and (15)(ii), constitute construction of a point source and
therefore, pursuant to ECL section 17-0505 and 17-0701, the owner or operator must
have coverage under a SPDES permit prior to commencing construction activity. The
owner or operator cannot wait until there is an actual discharge from the construction site
to obtain permit coverage.

Part 1. PERMIT COVERAGE AND LIMITATIONS
A. Permit Application
This permit authorizes stormwater discharges to surface waters of the State from
the following construction activities identified within 40 CFR Parts 122.26(b)(14)(x),
122.26(b)(15)(i) and 122.26(b)(15)(ii), provided all of the eligibility provisions of this
permit are met:
1. Construction activities involving soil disturbances of one (1) or more acres;
including disturbances of less than one acre that are part of a larger common
plan of development or sale that will ultimately disturb one or more acres of
land; excluding routine maintenance activity that is performed to maintain the
original line and grade, hydraulic capacity or original purpose of a facility;
2. Construction activities involving soil disturbances of less than one (1) acre
where the Department has determined that a SPDES permit is required for
stormwater discharges based on the potential for contribution to a violation of a
water quality standard or for significant contribution of pollutants to surface
waters of the State.
3. Construction activities located in the watershed(s) identified in Appendix D that
involve soil disturbances between five thousand (5,000) square feet and one
(1) acre of land.
B. Effluent Limitations Applicable to Discharges from Construction Activities
Discharges authorized by this permit must achieve, at a minimum, the effluent
limitations in Part 1.B.1. (a)— (f) of this permit. These limitations represent the degree of
effluent reduction attainable by the application of best practicable technology currently
available.
1. Erosion and Sediment Control Requirements - The owner or operator must
select, design, install, implement and maintain control measures to minimize
the discharge of pollutants and prevent a violation of the water quality
standards. The selection, design, installation, implementation, and
maintenance of these control measures must meet the non-numeric effluent
limitations in Part 1.B.1.(a) — (f) of this permit and be in accordance with the
New York State Standards and Specifications for Erosion and Sediment
Control, dated November 2016, using sound engineering judgment. Where
control measures are not designed in conformance with the design criteria
included in the technical standard, the owner or operator must include in the
Stormwater Pollution Prevention_Plan ("SWPPP") the reason(s) for the
1
(Part I.B.1)
deviation or alternative design and provide information which demonstrates that
the deviation or alternative design is equivalent to the technical standard.
a. Erosion and Sediment Controls. Design, install and maintain effective
erosion and sediment controls to minimize the discharge of pollutants and
prevent a violation of the water quality standards. At a minimum, such
controls must be designed, installed and maintained to:
(i) Minimize soil erosion through application of runoff control and soil
stabilization control,measure to minimize pollutant discharges;
(ii) Control,stormwater discharges, including both peak flowrates and total
stormwater volume, to minimize-channel and streambank erosion and
scour in the immediate vicinity of the discharge points;
(iii) Minimize the amount of soil exposed during construction activity;
(iv) Minimize the disturbance of steep slopes;
(v) Minimize sediment discharges from the site;
(vi) Provide and maintain natural buffers around surface waters, direct
stormwater to vegetated areas and maximize stormwater infiltration to
reduce pollutant discharges, unless infeasible;
(vii) .Minimize soil compaction. Minimizing soil compaction is not required
where the intended function of a specific area of the site dictates that it
be compacted;
(viii) Unless infeasible, preserve a sufficient amount of topsoil to complete
soil restoration and establish a uniform, dense vegetative cover; and
(ix) Minimize dust. On areas of exposed soil, minimize dust through the
appropriate application of water or other dust suppression techniques
to control the generation of pollutants that could be discharged from
the site.
b. Soil Stabilization. In areas where soil disturbance activity has temporarily
or permanently ceased, the application of soil stabilization measures must
be initiated by the end of the next business day and completed within
fourteen (14) days from the date the current soil disturbance activity ceased.
For construction sites that directly discharge to one of the 303(d) segments
2
(Part LB 1 b)
listed in Appendix E or is located in one of the watersheds listed in
Appendix C, the application of soil stabilization measures must be initiated
by the end of the next business day and completed within seven (7) days
from the date the current soil disturbance activity ceased. See Appendix A
for definition of Temporarily Ceased.
c. Dewatering. Discharges from dewatering activities, including discharges
from dewatering of trenches and excavations, must be managed by
appropriate control measures.
d. Pollution Prevention Measures. Design, install, implement, and maintain
effective pollution prevention measures to minimize the discharge of
pollutants and prevent a violation of the water quality standards. At a
minimum, such measures must be designed, installed, implemented and
maintained to:
(i) Minimize the discharge of pollutants from equipment and vehicle
washing, wheel wash water, and other wash waters. This applies to
washing operations that use clean water only. Soaps, detergents and
solvents cannot be used;
(ii) Minimize the exposure of building materials, building products,
construction wastes, trash, landscape materials, fertilizers, pesticides,
herbicides, detergents, sanitarywaste, hazardous and toxic waste, and
other materials present on the site to precipitation and to stormwater.
Minimization of exposure is not required in cases where the exposure
to precipitation and to stormwater will not result in a discharge of
pollutants, or where exposure of a specific material or product poses
little risk of stormwater contamination (such as final products and
materials intended for outdoor use) ; and
(iii) Prevent the discharge of pollutants from spills and leaks and
implement chemical spill and leak prevention and response
procedures.
e. Prohibited Discharges. The following discharges are prohibited:
(i) Wastewater from washout of concrete;
(ii) Wastewater from washout and cleanout of stucco, paint, form release
oils, curing compounds and other construction materials;
3
(Part LBA.e.in)
(iii) Fuels, oils, or other pollutants used in vehicle and equipment operation
and maintenance;
(iv) Soaps or solvents used in vehicle and equipment washing; and
(v) Toxic or hazardous substances from a spill or other release.
f. Surface Outlets. When discharging from basins and impoundments, the
outlets shall be designed, constructed and maintained in such a manner
that sediment does not leave the basin or impoundment and that erosion at
or below'the outlet does not occur.
C. Post-construction Stormwater Management Practice Requirements
1. The owner or operator of a construction activity that requires post-construction
stormwater management practices pursuant to Part III.C. of this permit must
select, design, install, and maintain the,practices to meet the performance
criteria in the New York State Stormwater Management Design Manual
("Design Manual'), dated January 2015, using sound engineering judgment.
Where post-construction stormwater management practices ("SMPs") are not
designed in conformance"with the performance criteria in the Design Manual,
the owner or operator must include in the SWPPP the reason(s)for the
deviation or alternative design and provide information which demonstrates that
the deviation or alternative design is equivalent to the technical standard.
2. The owner or operator of a construction activity that requires post-construction
stormwater management practices pursuant to Part III.C. of this permit must
design the practices to meet the applicable sizing criteria in Part I.C.2.a., b., c.
or d. of this permit.
a. Sizing Criteria for New Development
(i) Runoff Reduction Volume ("RRv"): Reduce the total Water Quality
Volume ("WQv")'by application of RR techniques and standard SMPs
with RRv capacity. The total WQv shall be calculated in accordance
with the criteria in Section 4.2 of the Design Manual.
(ii) Minimum RRv and Treatment of Remaining Total WQv: Construction
activities that cannot meet the criteria in Part I.C.2.a.(i) of this permit
due to site limitations shall direct runoff from all newly constructed
impervious'areas to a RR technique or standard SMP with RRv
capacity unless infeasible. The specific site limitations that prevent the
reduction of 100% of the WQv shall be documented in the SWPPP.
4
(Part I C.2 a fl)
For each impervious area that is not directed to a RR technique or
standard SMP with RRv capacity, the SWPPP must include
documentation which demonstrates that all options were considered
and for each option explains why it is considered infeasible.
In no case shall the runoff reduction achieved from the newly
constructed impervious areas be less than the Minimum RRv as
calculated using the criteria in Section 4.3 of the Design Manual.
The remaining portion of the total WQv that cannot be reduced shall be
treated by application of standard SMPs.
(iii) Channel Protection Volume ("Cpv"): Provide 24 hour extended
detention of the post-developed 1-year, 24-hour storm event;
remaining after runoff reduction. The Cpv requirement does not apply
when:
(1) Reduction of the entire Cpv is achieved by application of runoff
reduction techniques or infiltration systems, or
(2) The site discharges directly to tidal waters, or fifth order or larger
streams.
(iv) Overbank Flood Control Criteria ("Qp"): Requires storage to attenuate
the post-development 10-year, 24-hour peak discharge rate (Qp) to
predevelopment rates. The Qp requirement does not apply when:
(1) the site discharges directly to tidal waters or fifth order or larger
streams, or
(2) A downstream analysis reveals that overbank control is not
required.
(v) Extreme Flood Control Criteria ("Qf'): Requires storage to attenuate
the post-development 100-year, 24-hour peak discharge rate (Qf) to
predevelopment rates. The Qf requirement does not apply when:
(1) the site discharges directly to tidal waters or fifth order or larger
streams, or
(2) A downstream analysis reveals that overbank control is not
required.
b. Sizing Criteria for New Development in Enhanced Phosphorus
Removal Watershed
(i) Runoff Reduction Volume (RRv): Reduce the total Water Quality
Volume (WQv) by application of RR techniques and standard SMPs
with RRv capacity. The total WQv is the runoff volume from the 1-year,
24 hour design storm over the post-developed watershed and shall be
5
(Part I C.2 b.i)
calculated in accordance with the criteria in Section 10.3 of the Design
Manual.
(ii) Minimum RRv and Treatment of Remaining Total WQv: Construction
activities that cannot meet the criteria in Part I.C.2.b.(i) of this permit
due to site limitations shall direct runoff from all newly constructed
impervious areas to a RR technique or standard SMP with RRv
capacity unless infeasible. The specific site limitations that prevent the
reduction of 100% of the WQv shall be documented in the SWPPP.
For each impervious area that is not directed to a RR technique or
standard SMP with RRv capacity, the SWPPP must include
documentation which demonstrates that all options were considered
and for each option explains why it is considered infeasible.
In no case shall the runoff reduction achieved from the newly
constructed impervious areas be less than the Minimum RRv as
calculated using the criteria in 'Section 10.3 of the Design Manual.
The remaining portion of the total WQv that cannot be reduced shall be
treated by application of standard SMPs.
(iii) Channel Protection Volume (Cpv): Provide 24 hour extended detention
of the{post-developed 1-year, 24-hour storm event; remaining after
runoff reduction. The Cpv requirement does not apply when:
(1) Reduction of the entire Cpv is achieved by application of runoff
reduction techniques or infiltration systems, or
(2) The site discharges directly to tidal waters, or fifth order or larger
streams.
(iv) Overbank Flood Control Criteria (Qp): Requires storage to attenuate
the post-development 10-year, 24-hour peak discharge rate (Qp) to
predevelopment rates. The Qp requirement does not apply when:
(1) the site discharges directly to tidal waters or fifth order or larger
streams, or
(2) A downstream analysis reveals that overbank control is not
required.
(v) Extreme Flood Control Criteria (Qf): Requires storage to attenuate the
post-development 100-year, 24-hour peak discharge rate (Qf) to
predevelopment rates. The Qf requirement does not apply when:
(1) the site discharges directly to tidal waters or fifth order or larger
streams, or
(2) A downstream analysis reveals that overbank control is not
required.
6
(Part I C.2.c)
c. Sizing Criteria for Redevelopment Activity
(i) Water Quality Volume (WQv): The WQv treatment objective for
redevelopment activity shall be addressed by one of the following
options. Redevelopment activities located in an Enhanced Phosphorus
Removal Watershed (see Part III.B.3. and Appendix C of this permit)
shall calculate the WQv in accordance with Section 10.3 of the Design
Manual. All other redevelopment activities shall calculate the WQv in
accordance with Section 4.2 of the Design Manual.
(1) Reduce the existing impervious cover by a minimum of 25% of the
total disturbed, impervious area. The Soil Restoration criteria in
Section 5.1.6 of the Design Manual must be applied to all newly
created pervious areas, or
(2) Capture and treat a minimum of 25% of the WQv from the disturbed,
impervious area by the application of standard SMPs; or reduce 25%
of the WQv from the disturbed, impervious area by the application of
RR techniques or standard SMPs with RRv capacity., or
(3) Capture and treat a minimum of 75% of the WQv from the disturbed,
impervious area as well as any additional runoff from tributary areas
by application of the alternative practices discussed in Sections 9.3
and 9.4 of the Design Manual., or
(4) Application of a combination of 1, 2 and 3 above that provide a
weighted average of at least two of the above methods. Application
of this method shall be in accordance with the criteria in Section
9.2.1(B) (IV) of the Design Manual.
If there is an existing post-construction stormwater management
practice located on the site that captures and treats runoff from the
impervious area that is being disturbed, the WQv treatment option
selected must, at a minimum, provide treatment equal to the treatment
that was being provided by the existing practice(s) if that treatment is
greater than the treatment required by options 1 —4 above.
(ii) Channel Protection Volume (Cpv): Not required if there are no
changes to hydrology that increase the discharge rate from the project
site.
(iii) Overbank Flood Control Criteria (Qp): Not required if there are no
changes to hydrology that increase the discharge rate from the project
site.
(iv) Extreme Flood Control Criteria (Qf): Not required if there are no
changes to hydrology that increase the discharge rate from the project
site
7
(Part I.C.2.d)
d. Sizing Criteria for Combination of Redevelopment Activity and New
Development
Construction projects that include both New Development and Redevelopment
Activity shall provide post-construction stormwater management controls that
meet the sizing criteria calculated as an aggregate of the Sizing Criteria in Part
I.C.2.a. or b. of this permit for the New Development portion_of the project and
Part I.C.2.c of this permit for Redevelopment Activity portion of the project.
D. Maintaining Water Quality
The Department expects that compliance with the conditions of this permit will control
discharges necessary to meet applicable water quality standards. It shall be a violation
of the ECL for any discharge to either cause or=ntribute to a violation of water quality
standards as contained in Parts 700 through 705 of Title 6 of the Official Compilation of
Codes, Rules and Regulations of the State of New York, such as:
1. There shall be no increase in turbidity that will cause a substantial visible contrast
to natural conditions;
2. There shall be no increase in suspended, colloidal or settleable solids that will
cause deposition or impair the waters for their best usages; and
3. There shall be no residue from oil and floating substances, nor visible oil film, nor
globules of grease.
If there is evidence indicating that the stormwater discharges authorized by this permit
-are causing, have the reasonable potential to cause, or are contributing.to a violation of
the water quality standards; the owner or operator must take appropriate corrective
action in accordance with Part IV.C.5. of this general permit and document in
accordance with Part IV.C.4. of this general permit. To address the water quality
standard violation 'the owner or operator may need to provide additional information,
include and implement appropriate controls in the SWPPP-to correct the problem, or
obtain an individual SPDES permit.
If there is evidence indicating that despite compliance with the terms and conditions of
this general permit it is demonstrated that the stormwater discharges authorized by this
permit are causing or contributing to a violation of water quality standards, or if the
Department determines that a modification of the permit is ,necessary to prevent a
violation of water quality standards, the authorized discharges will no longer be eligible
for coverage under this permit. The Department may require the owner or operator to
obtain an individual SPDES permit to continue discharging.

Appendix A
Steep Slope — means land area designated on the current United States Department of
Agriculture ("USDA") Soil Survey as Soil Slope Phase "D", (provided the map unit name
is inclusive of slopes greater than 25%) , or Soil Slope Phase E or F, (regardless of the
map unit name), or a combination of the three designations.
Streambank— as used in this permit, means the terrain alongside the bed of a creek or
stream. The bank consists of the sides of the channel, between which the flow is confined.
Stormwater Pollution Prevention Plan (SWPPP) — means a project specific report,
including construction drawings, that among other things: describes the construction
activity(ies), identifies the potential sources of pollution at the construction site; describes
and shows the stormwater controls that will be used to control the pollutants (i.e. erosion
and sediment controls; for many projects, includes post-construction stormwater
management controls); and identifies procedures the owner or operator will implement to
comply with the terms and conditions of the permit. See Part III of the permit for a
complete description of the information that must be included in the SWPPP.
Surface Waters of the State shall be construed to include lakes, bays, sounds,
ponds, impounding reservoirs, springs, rivers, streams, creeks, estuaries, marshes,
inlets, canals, the Atlantic-ocean within the territorial seas of the state of New York and
all other bodies of surface water, natural or artificial, inland or coastal, fresh or salt,
public or private (except those private waters that do not combine or effect a junction
v with natural surface waters), which are wholly or partially within or bordering the state
or within its jurisdiction. Waters of the state are further defined in 6 NYCRR Parts 800 to
941.
Temporarily Ceased — means that an existing disturbed area will not be disturbed
again within 14 calendar days of the previous soil disturbance.
Temporary Stabilization - means that exposed soil has been covered with material(s)
as set forth in the technical standard, New York Standards and Specifications for
Erosion and Sediment Control, to prevent the exposed soil from eroding. The materials
can include, but are not limited to, mulch, seed and mulch, and erosion control mats
(e.g. jute twisted yarn, excelsior wood fiber mats).
Total Maximum Daily Loads (TMDLs) -A TMDL is the sum of the allowable loads of a
single pollutant from all contributing point and nonpoint sources. It is a calculation of the
maximum amount of a pollutant that a waterbody can receive on a daily basis and still
meet water quality standards, and an allocation of that amount to the pollutant's
sources. A TMDL stipulates wasteload allocations (WLAs)for point source discharges,
load allocations (LAs) for nonpoint sources, and a margin of safety (MOS).
Trained Contractor- means an employee from the contracting (construction) company,
identified in Part III.A.6., that has received four (4) hours of Department endorsed
46
Appendix A
training in proper erosion and sediment control principles from a Soil and Water
Conservation District, or other Department endorsed entity. After receiving the initial
training, the trained contractor shall receive four (4) hours of training every three (3)
years.
It can also mean an employee from the contracting (construction) company, identified in
Part I I I.A.6., that meets the qualified inspector qualifications (e.g. licensed Professional
Engineer, Certified Professional in Erosion and Sediment Control (CPESC), Registered
Landscape Architect, New York State Erosion and Sediment Control Certificate
Program holder, or someone working under the direct supervision of, and at the same
company as, the licensed Professional Engineer or Registered Landscape Architect,
provided they have received four (4) hours of Department endorsed training in proper
erosion and sediment control principles from a Soil and Water Conservation District, or
other Department endorsed entity).
The trained contractor is responsible for the day to day implementation of the SWPPP.
Uniform Procedures Act (UPA) Permit- means a permit required under 6 NYCRR
Part 621 of the Environmental Conservation Law (ECL), Article 70.
Water Quality Standard - means such measures of purity or quality for any waters in
