2.4 Threatened/Endangered Species
The parcel does not contain any threatened or Endangered Species.
5 of 20
2.5 Land Cover
The proj ect site is currently woods with an area devoid of vegetation due to the excavation.
2.6 Soils
� Oakville Loainy Fine Sand, (OaC)—(Rolling): This is a very deep,well drained soil formed in water sorted sand.
It is on glacial outwash plains,lake plains,and beach ridges. The permeability is rapid throughout the mineral soil.
The erosion factor is moderate. (Hydrologic Soil Type A)
2.7 Existing Land Use
The proj ect site is currently vacant land.
3.0 PROJECT DESCRIPTION
The proposed proj ect will include the development of a single family home with an accessory barn structure.
The proposed residence will be serviced by an individual well and wastewater treatment system. An easement is
proposed from Stafford Bridge Road to the land locked parcel which will include the driveway to the single
family residence. Disturbance of the existing vegetation will be minimized to the greatest extend possible.
4.0 STORMWATER EROSION AND SEDIMENT CONTROLS
Several types of temporary erosion and sediment controls are required during construction as shown on the
proj ect plans and per the General Permit. Guidelines and recommendations can be found in the "New York
Standards and Specifications for Erosion and Sediment Control."
Selection of temporary stormwater controls will be on an "as needed basis" and will depend on the specific
conditions of the site. Since site characteristics can change significantly during construction, it is important to
monitor the site regularly to ensure the proper selection and implementation of the necessary controls.
4.1 Erosion and Sedimentation Controls
Tempo�a�v Stabilization
These controls include, but are not limited to stabilized construction entrances, silt fence, construction fencing,
rolled erosion control product,mulch, soil stockpile areas, and staging and waste areas.
Stabilized Construction Ent�ance
This temporary structural measure is a stabilized pad of aggregate underlain with filter fabric located at any
point where traffic will be entering or leaving a construction site to or from a public right-of-way, street, alley,
sidewalk or parking area. The purpose of a stabilized construction entrance is to reduce or eliminate the
tracking of sediment onto public rights-of-ways or streets. The entrance shall be maintained in a condition
which will prevent tracking of sediment onto public right-of-way, street, alley, sidewalk or parking area. This
may require periodic top dressing with additional aggregate. This will remain in place and be maintained until
the proj ect site has been permanently stabilized.
Silt Fencin�
This temporary structural measure is a temporary barrier of geotextile fabric used to intercept sediment laden
runoff from small drainage areas of soiL It is installed along the perimeter of impacted areas and along the base
of fill slopes. Silt fencing is effective in reducing stormwater runoff velocities, assist in the deposition of
transported sediment load and prevent erosion of soils onto adjacent areas. Maintenance shall be performed
when the silt fencing has been damage or collapsed and material removed when "bulges" (generally when the
6 of 20
depth of sediment equals 1/3 of the fence height) develop in the silt fence. These will remain in place and be
maintained until the proj ect site has been permanently stabilized.
Construction Fencin�, Chain Link Fencin�o�Fla��in�
This temporary structural measure is installed along the perimeter of the proj ect area. In many cases the limits
of disturbance will coincide with the fencing or flagging or indicate buffer areas to be protected. The fencing or
flagging is effective when used to separate the proj ect area from the adj acent areas used by the public.
Construction Fencing, Chain Link Fencing or Flagging is relatively low maintenance, but should be repaired
when damaged. These will remain in place and be maintained until the project site has been permanently
stabilized.
Rolled Erosion Cont�ol Product(RECP)
This temporary structural measure is installed in areas that have steep slopes (generally greater than 3:1) to
stabilize the slope and reduce the erosion potential. RECP's types include jute netting, straw blankets, wood
fiber (excelsior) blankets, polypropylene blankets, straw-coconut blankets, coconut fiber blankets, etc. The
RECP's are typically impregnated with grass seed and sometimes stapled to the exposed soil. Inspect RECP's
after each rain event and repair if needed, including installing additional material and staples. If the RECP is
undermined, roll back the material, add soil to finish grade and replace the material with staples as needed. In
most cases,these will remain in place permanently(degrading over weeks,months or even years).
Mulchin�
This temporary structural measure is a plant residue or other suitable material that is applied to the bare soil
surface to prevent soil erosion. Mulching is effective in conserving moisture and modifying surface soil
temperature fluctuations, prevent surface compaction or crushing, reduce runoff and erosion, control weeds and
help establish plant cover. Mulching types include plant fibers such as hay or straw, chipped native materials,
green or composted organic materials, wood or bark chips, hydraulic mulches from recycled paper, hydraulic
mulches from wood fiber, and hydraulic matrices (bonded fiber matrix). Inspect mulches after each rain event
and repair if needed, including applying additional mulch. These will remain in place permanently (degrading
over weeks,months or even years).
Soil Stockpile A�eas
These are approved locations where topsoil and other soil materials may be stored. These stockpiles will be
protected from erosion by a number of inethods, including installing silt fencing around the down gradient
perimeter of the stockpile and seeding and mulching the stockpile when not in use for more than 14 days,unless
the stockpile will be active within 21 days.
Sta�in�and Waste A�eas
These are approved locations where non-soil, non-erodible materials may be stored. Soils shall not be stored in
these areas.
Proj ect plans specify the location, size, quantity, and details of the selected temporary measures. Steep slopes
and exposed soils should be stabilized with silt fences, mulching blankets, geo-textiles, geo-synthetic drainage
netting, hay or any other stabilization measure shall be used that will significantly reduce the risk of erosion.
Stabilization measures should be initiated as soon as practical in portions of the site where construction activities
have temporarily or permanently ceased, but in no case more than 14 days. All disturbed areas will be
reclaimed by use of permanent vegetation, impervious surfaces including structures and paved driveways and
roads.

4.2 Other Pollutant Controls
Paints and Solvents
During construction, temporary structures such as construction trailers may be moved on site to store items such
as paints, solvents and gasoline pertinent to the continuation of construction activities. The intention of these
structures is to shelter potential contaminants from stormwater and reduce the potential of toxic chemicals from
entering the stormwater runoff due to construction activities.
Solvents and detergents may be stored on-site that will be used for regular cleaning and maintenance of
construction vehicles or temporary structures. Solvents shall be used in cleaning machinery pursuant to 6
NYCRR Part 750. After use, solvents shall be disposed of in approved containers and removed from site at
scheduled intervals. Vehicle wash water that contains detergents must be disposed of into the sanitary sewer.
Conc�ete Washout
In the event concrete is delivered and placed on site, delivery trucks will require an area to stockpile barrel/cone,
shutes, and other equipment. A centrally located concrete washout area approximately 15-feet square and 2.5-
feet deep shall be constructed and lined with a 10 mil minimum poly/plastic liner. This washout area shall be
enclosed by silt fence, located next to a paved road and situated a minimum of 50-feet from a watercourse. If
required, temporary diversion dikes shall be constructed around washout area to prevent stormwater from
entering washout location.
Waste material from concrete washout operations shall be periodically removed and legally disposed of when
two-thirds of the washout storage area has accumulated with material and a new liner shall be installed. At the
end of construction all material from the washout area shall be removed and disposed of.
Mate�ial Stockpile A�ea
Materials utilized for construction or equipment storage areas shall be constructed to prevent runoff from
coming in contact with stored items/equipment. Contractor shall clear area(s) indicated on proj ect plans and
excavate into native material a minimum of 6-inches for placement of Marafi 100X fabric and 6-inch stone pad.
Contractor to verify that area to be utilized is dry and stable and notify engineer if area shown on proj ect plans is
not adequate. No materials/equipment shall be constructed within 50-feet of a water course.
If necessary, temporary perimeter dikes shall be constructed to prevent runoff from entering the stone pad. Silt
fencing shall be installed a minimum of 5-feet downslope of storage area. Should additional area be required the
contractor shall construct additional storage areas as necessary in conformance with the proj ect plans, any
additional areas are to be documented by contractor in the on-site SWPPP.
Soil Stockpile A�ea
During cut and fill operations topsoil and other excavated material will be stockpiled on site for placement in fill
areas as construction progresses. In an effort to prevent runoff from coming in contact with stockpiled soils or
soils from entering existing watercourses, managed stockpile areas shall be constructed in the areas indicated on
the project plans. The contractor shall verify that the proposed areas are dry and stable, and to notify the
engineer if area is not adequate. No soils or excavated materials shall be stockpiled within 50-feet of a
watercourse.
Contractor shall install silt fence 5-feet downslope of each pile and construct any perimeter diversion dikes if
required. Material shall be stabilized with seed and mulch if not to be utilized/disturbed within 14 days unless
stockpile is projected to be disturbed within 21 days. Seed and much will reduce wind blown and rain instigated
erosion from the stockpiles exposed steep slopes.

Fuels
Fuel for construction equipment shall either be obtained from a licensed distributor of petroleum products or
from an approved above ground storage tank on site. A distributor may be contracted to arrive on site
periodically and fill all equipment as necessary. All distributors of petroleum products must have adequate
liability insurance to mitigate and clean up any spills that occur on site as well as obtain appropriate permits and
licenses from the NYSDEC. All above ground storage tanks with a combined capacity of 1,100 gallons shall be
installed pursuant to 6 NYCRR Part 614 Standards for New and Substantially Modified Petroleum Storage
Facilities.
Fuel from construction vehicles may come into contact with stormwater when vehicles are stored outside. Good
housekeeping and preventative maintenance procedures shall be implemented to ensure fuel spills and leaks are
minimized during refueling and storage. Any small-scale fuel or oil spills must be remedied immediately and
contaminated soils shall be disposed of appropriately. The designated spill prevention and response team shall
handle large-scale gasoline spills.
Oil and other petroleum products may be stored on site in limited quantities to ensure the continued operation of
construction equipment in the event a scheduled delivery is unavailable. Items shall be stored in their original
containers within temporary structures and shall not be exposed to stormwater. Used oil and petroleum products
shall be stored in approved containers until recycled or disposed of at an approved disposal facility.
Tempora�v Facilities
Temporary sanitary facilities may be located on site for construction workers. This facility shall be located in an
accessible and visible location. Such a facility shall be leak and tip proof. A waste management company may
be contracted to arrive on site and provide the routine pumping and sanitization of the facility. Such a company
shall have adequate liability insurance to mitigate and clean up any spills that occur on site as well as
appropriate permits and licenses from the NYSDEC.
Dust Cont�ol
Construction traffic must enter and exit the site at the stabilized construction entrance. The purpose is to trap
dust and mud that would otherwise be carried off-site by construction traffic. Water trucks will be used as
needed during construction to reduce dust generated on the site. Dust control must be provided by the General
Contractor to a degree that is acceptable to the Owner, and in compliance with applicable local and state dust
control regulations.
Solid Waste
No solid materials, including building materials, are allowed to be discharged from the site with storm water.
All solid waste, including disposable materials incidental to the major construction activities, must be collected
and placed in containers. The containers will be emptied periodically by a contract trash disposal service and
hauled away from the site.
The�mal Pollution
Stormwater that comes in contact with roadways, driveways, parking lots or other impermeable surfaces may
increase in temperature during warm weather. If stormwater is discharged into surface water bodies, the
temperature of the water body may also increase, potentially threatening plant and animal species sensitive to
temperature changes as well as providing an environment that may cause nuisance species to flourish. After
development is complete, impervious areas shall be graded to sheet flow to adjacent vegetated areas before
entering surface waters.
4.3 Best Management Practices
Throughout construction, care shall be taken to ensure sediment does not enter surface water bodies and
chemicals do not enter stormwater, potentially contaminating surface and groundwater supplies. The following
9 of 20
Best Management Practices (BMP) shall be observed to maintain responsible environmental practices on the
construction site.
Good Housekeepin�
Good housekeeping is essential to reducing the risk of contaminating runoff waters during every stage of
construction. The General Contractor shall ensure supervisors train each employee in good housekeeping
practices as they pertain to the implementation of this SWPPP.
Immediately following mobilization, the General Contractor shall take an inventory of all equipment and
containers containing hazardous or toxic materials and submit this inventory to the Owner to keep on-site with
this Stormwater Pollution Prevention Plan. This inventory shall be updated regularly to reflect changes in the
quantity or type of hazardous and toxic materials stored on site. In the event of a spill, the Spill Response Team
can refer to the inventory if the contents of the spill are unknown.
All equipment shall be operational while it is stored on site. Inspections shall be conducted regularly to ensure
all equipment is free of leaks and that oil and grease are not in contact with soils or stormwater. Portable
equipment such as chain saws, drills as well as hand tools must be placed within a trailer or under cov er at the
end of each work day.
A storage area shall be designated on-site where all hazardous or toxic materials are stored. Each employee
shall return the materials to the designated storage area following use. Chemicals, including oil, grease, solvents
and detergents shall be stored on-site in approved containers only. Used chemicals shall be disposed of in refuse
containers and removed periodically. Containers shall be regularly inspected to ensure the integrity of the
container and seals to prevent leaks.
A scheduled clean-up shall occur at the end of each workweek. During this clean up, empty containers of
solvents, oils, grease,paints and detergents shall be disposed of, containers of gasoline shall be placed in trailers
where they are not in contact with stormwater and the inventory shall be updated. Empty containers shall not be
permitted on the ground.
P�eventative Maintenance
All on-site vehicles must be inspected regularly for oil and grease leaks. All leaks shall be repaired immediately
upon obtaining the appropriate equipment. If the leak cannot be fixed immediately, it shall be temporarily
mitigated to prevent the flow of contaminants onto the soil and potentially into the stormwater. If necessary,the
reservoir will be drained to stop the flow of contaminants or the vehicle will be moved under cover. Drip pans
shall be used when performing any maintenance or cleaning on construction vehicles.
Spill Prevention and Response
The safety of employees and neighbors shall be of utmost concern when hazardous or toxic chemicals are stored
or utilized on-site. Materials Safety Data Sheets (MSDS) shall be obtained for all toxic or hazardous substances
that are stored on-site to provide employees with a valuable database in assessing risk in the event of a spill.
Any above ground storage tanks on site shall be installed pursuant to 6 NYCRR Part 614. According to the
New York State "Minimum Standards for New and Substantially Modified Above Ground Storage Facilities",
all tanks installed must meet or exceed the design criteria in one or more of the following design or
manufacturing standards: UL No. 142, UL No. 58, API Standard No. 650, API Standard No. 620, CAN4-S601-
M84 or CAN4-S630-M84. Tanks constructed of wood, concrete, aluminum, fiberglass reinforced plastic as well
as riveted or bolted steel tanks are not permitted. All tanks must have installed leak detection systems, secondary
containment, corrosion protection, and undergo periodic monitoring pursuant to all Part 614 requirements.
Should a spill occur, trained individuals shall be on-call at all times to mitigate the potential negative effects of a
spill. The General Contractor shall have trained employees knowledgeable in the location of sorbent, brooms,
10 of 20
rags and mops in the event of a small-scale spill. An inventory of equipment and its location shall be posted in a
visible location as well as kept in proximity to this SWPPP. If the General Contractor does not have Hazardous
Materials trained employees on site, a firm that specializes in handling spills, soil and water contamination shall
be called.
After a spill occurs, all personnel not trained in hazardous materials spill response shall be asked to evacuate the
immediate area. The New York State NYSDEC of Environmental Conservation (NYSDEC) Spill Response
Team shall be called to investigate the spill and determine if additional actions should be taken to ensure the
safety of personnel and nearby residents. Should any employee have a suspected injury, a local emergency
squad must be contacted immediately.
5.0 CONSTRUCTION SEQUENCE SCHEDULING (PHASING PLAN)
Temporary stabilization methods will be implemented before construction begins and will be continuously
modified throughout the proj ect to provide the best methods for stormwater management and pollution
prevention. For more details pertaining to construction sequence, please refer to the "NYSDEC Instruction
Manual for Stormwater Construction Permit" pages 23-26. The proj ect is anticipated to begin in summer of
2017 and end in the fall of 2018, although full build out of lots will be based on market conditions. Phasing of
activities is as follows:
P�e-Const�uction Activities
� Owner and Contractor to review this document with all employees and subcontractors to gain
understanding of the management features and sediment controls outlined in this document as they
relate to the engineered project plans.
• Perform a site investigation to identify all natural resources and mark and protect them as necessary i.e.
trees, vegetation, and wetlands. Note any discrepancies that may exist between the site and what is
shown on the engineered proj ect plans as they pertain to existing watercourses, ground cover,
topography, wetlands, etc.
� Notify design engineer of any discrepancies.
• Identify on site and downstream surface water bodies and install controls to protect them from
sedimentation.
• Establish a temporary stabilized construction entrance per the New York State Standa�ds and
Specifications fo�E�osion and Sediment Cont�ol Handbook, July 2016, to capture mud and debris from
the tires of construction vehicles.
• Install perimeter sediment controls such as silt fence as shown on the project plans.
• All earth disturbance during this phase should be limited to work necessary to install erosion and
sedimentation controls.
Du�ing Const�uction Activities
• Install runoff and drainage controls as shown on the proj ect plans and as necessary. These controls
should reduce run-off flow rates and velocities as well as divert off site and clean run-off.
� Stabilize the conveyance system i.e. ditches, swales, berms etc. by seeding, mulching, installing rock
check dams.
� Stabilize all run-off outlets as shown on the project plans and as necessary.
• Limit soil disturbance to small areas and preserve as much of the existing vegetation as practical.
• All topsoil stockpiles should be staged in an area away from surface waters and storm drains and should
be protected and stabilized.
• Earth disturbance is not allowed in established buffers, within any regulated distance from wetlands,
within the high water line of a body of water affected by tidal action or other such protected zones.
• At any location where surface run-off from disturbed or graded areas may flow off-site, sedimentation
control measures must be installed to prevent sedimentation from being transported.
11 of 20
• Regular inspections and maintenance should be performed as described in the following section.
� Construct temporary material storage and soil stockpile areas
• In the event concrete is delivered and placed on site, delivery trucks will require an area to truck
barrel/cone, chutes, and other equipment. A centrally located concrete washout area approximately 15-
feet square and 2.5-feet deep shall be constructed. This washout area shall be enclosed by silt fence,
located next to a paved road and situated a minimum of 100-feet from a watercourse. If required,
temporary diversion dikes shall be constructed around washout area to prevent stormwater from
entering washout location.
� Waste material from concrete washout operations must shall be periodically removed and legally
disposed of when two-thirds of the washout storage area has accumulated with material. At the end of
construction all material from the washout area shall be removed and disposed of.
• Remove perimeter silt fence when a permanent stand of vegetation is achieved.
� Clear brush and trees within proposed building envelope.
� Construct a temporary material stockpile area on individual lot for homebuilding construction. Size of
area may vary per homebuilder; however general material/storage stockpile measures shown on
construction drawings shall be followed.
• Perform required grading and homebuilding operations
• Perform required utility connections
� Stabilize lawn areas not to be disturbed with seed and mulch
• Pave driveway.
� Stabilized remaining areas.
• Remove temporary erosion and sediment control practices (i.e. silt fence)
6.0 IMPLEMENTING THE SWPPP
6.1 Employee Training
All employees on site shall be aware of the stipulations of this SWPPP as it pertains to their everyday activities.
All employees must be able to recognize potential problems and have the ability to provide temporary
stabilization measures, as appropriate, to mitigate stormwater runoff before problems occur. The NYSDEC
periodically holds workshops on erosion and sediment controL It is recommended that on site personnel attend
these workshops to keep training current and up to date. All contractors and subcontractors involved with soil
disturbing activities shall have at least one trained individual from their company be responsible for
implementation of the SWPPP and be on site when soil disturbing activities are occurring.
6.2 Site Inspections
The Owner shall ensure all erosion and sediment controls identified in the SWPPP are maintained and effective
from commencement of construction to the filing of the NOT. The Owner shall inspect the erosion and
sediment controls identified in the SWPPP to ensure they are installed and maintained in accordance with the
most current version of the "New Yo�k Standa�ds and Specifications fo�E�osion and Sedi�nent Cont�ol". It is
the responsibility of the Owner, Contractor and subcontractors to continuously monitor construction activities to
ensure the measures outlined in this report are being implemented. The owner shall have a qualified inspector
perform site inspections for construction activities identified in Table 1 and 2 of Appendix B of the NYSDEC
SPDES General Permit (GP-0-15-002). A qualified professional is defined as a person such as a Professional
Engineer, Certified Professional in Erosion and Sediment Control (CPESC)or a soil scientist.
Once construction begins regular inspection of construction activities by the qualified professional are required
at least once every seven (7) calendar days to ensure deficiencies regarding erosion and sedimentation are
reported and corrected. Areas which have not been fully stabilized, areas used for materials storage and all
12 of 20
structural control measures must be inspected to monitor erosion and as sess the risk of sedimentation. The
qualified inspector shall certify all inspection reports. Inspection reports will be faxed to the Owner, Contractor
and subcontractors within one business day of the completion of the inspection. Corrective action to address any
deficiencies at the site shall be initiated within one business day of receiving the notification.
All erosion and sediment controls must be installed and maintained according to the New Yo�k Standa�ds and
Specifications fo�E�osion and Sedi�nent Cont�ol. The main items to consider are:
1. Site Stabilization - All bare/exposed soils must be stabilized by an established vegetation, straw or
mulch, matting, rock or other approved product such as rolled erosion control product. Seeding of areas
along with mulching is encouraged, however seeding alone is not considered acceptable for proper
stabilization.
2. Sediment Barriers - Barriers must be properly installed at all necessary perimeter and sensitive
locations.
3. Slopes - All slopes and grades must be properly stabilized with approved methods. Rolled erosion
control products must be used on all slopes greater than 3/1, or where conditions for erosion dictate such
measures.
4. Soil Stockpiles - Stockpiled soils must be protected by the use of established vegetation, an anchored-
down straw or mulch, rolled erosion control product or other durable covering. A barrier must be
installed around the pile to prevent erosion away from that location.
5. Construction Entrance - All entrance/exit locations to the site must be properly stabilized and must be
maintained to accommodate snow management as set forth in the New York Standards and
Specifications for Urban Erosion and Sediment Control.
6. Snow Management - Snow management must not destroy or degrade erosion and sediment control
practices.
At the end of the construction season when soil disturbance activities will be finalized or suspended until the
following spring, it may be desirable to reduce the frequency of the required inspections in accordance with
NYSDEC Winter Site Stabilization Standards and Specifications. To be allowed to reduce inspection
frequencies, the owner must notify the Regional Office stormwater contact person in writing prior to reducing
the frequency of inspections. During periods of reduced inspection frequency, inspections must still be
completed at least every thirty(30) days.
The owner shall complete stabilization activities (perimeter controls, traps, barriers etc) before proper
installation is precluded by snow cover or frozen ground. If vegetation is desired, seeding, planting, and/or
sodding must be scheduled to avoid die-off from fall frosts and allow for proper germination/establishment.
Frozen ground, winter conditions and equipment can affect erosion and sediment control practices. Check for
damage during monthly inspections and repair as necessary. This is especially important during thaws and prior
to spring rain events. Weekly inspections must resume no later than March 15 or as directed by the Department.
If the soil disturbance is completely suspended and the site is properly stabilized it may be desirable to reduce
the inspection frequency to a minimum of once every thirty (30) calendar days. To be allowed to reduce
inspection frequencies, the owner must notify the Regional Office stormwater contact person in writing prior to
reducing the frequency of inspections.
The SWPPP shall be reviewed to evaluate its overall effectiveness in preventing sediment laden stormwater
runoff. Temporary stabilization methods shall be assessed, and new methods shall be established, should any
method be determined to be inadequate. All changes shall be included in the SWPPP.

A current copy of the SWPPP must be maintained on site at all times. The Owner shall maintain a copy of the
General Permit, NOI, NOI Acknowledgement Letter, Contractor certifications, and inspection reports in the on
site Logbook. All record keeping shall be maintained on site and be made available to the permitting authority
upon request.
6.3 Maintenance
It shall be necessary to maintain all temporary controls installed as well as vegetative measures across the site.
During construction, maintenance of these stabilization measures shall be the responsibility of the Contractors
and/or appropriate subcontractors. Vegetative plantings must not be allowed to become overgrown. Vegetation
shall be removed should it be ineffective and be replaced with a variety of grasses, trees and shrubs more
suitable for preventing stormwater runoff. Silt fences must be inspected regularly to ensure that they are still
effective and their capability to reduce stormwater runoff has not been reduced due to prolonged sun exposure.
Guidelines and recommendations for installation and maintenance practices can be found in the "New Yo�k
Standa�ds and Specifications fo�E�osion and Sediynent Cont�ol".
6.4 Certification
Prior to starting construction, the Owner must certify that to the best of their knowledge this SWPPP was
prepared in accordance with the requirements in the NYSDEC SPDES General Permit and that it meets all
federal, state and local erosion and sediment control requirements. The certifying statement is contained in the
NOI.
All appropriate contractors and subcontractors involved in soil disturbing activities are responsible for fully
implementing the SWPPP. They are required to sign the certifying statement presented in Appendix A of this
report.
All weekly inspection reports are to be certified by the qualified inspector performing the on site inspections.
6.5 Proj ect Completion
At the time of final stabilization, the OWner's Site Inspector shall perform a final site assessment to verify that
all construction activity identified in the SWPPP has been completed, that all disturbance has undergone final
stabilization and that all temporary erosion and sediment controls have been removed. Final stabilization as
defined in the General Permit "means that all soil disturbance activities have ceased and a uniform, perennial
vegetative cover with a density of eighty (80) percent over the entire pervious surface has been established; or
other equivalent stabilization measures, such as permanent landscape mulches, rock rip-rap or washed/crushed
stone have been applied on all disturbed areas that are not covered by permanent structures, concrete or
pavement".
Once a final site assessment has been conducted, a NOT shall be prepared and certified by the Owners' Site
Inspector as described in Section 1.1 of this report. The NOT should then be signed by the Owner and submitted
to the NYSDEC. All record keeping must be kept for at least five (5) years from the date that the site has
achieved final stabilization.
