PROJECT INFORMATION
Project Description
This project will consist of the construction of a commercial building addition with an approximate footprint of 7,600 SF, as well as
a bituminous driveway.
Disturbed Area & Impervious Surface Tabulation
(within proposed construction area)
Project not subject to
SEDIMENT AND OTHER POLLUTANTS
This SWPPP has been designed mainly to provide erosion and sediment control of naturally occurring soils at this site (ie: sands, loams,
and clays). Although this SWPPP does address pollution prevention of other man-made materials, it is assumed that these materials will
consist of debris from existing structures and pavements to be demolished, or debris and chemicals (ie: fuels, new paints, etc.) resulting
from new construction.
There are no known solid wastes or hazardous materials buried below grade at this site. If such wastes or hazard materials are
discovered during construction, the SWPPP Coordinator (described below) will be responsible for notifying the Engineer. This SWPPP will
then be revised to address he presence and disposal of these additional pollutants
EROSION PREVENTION AND SEDIMENT CONTROL BMPS
Standards and References
Materials and construction methods of all BMPs included in this SWPPP shall be as per the Minnesota Department of
Transportation (MNDOT) Standard Specifications for Construction, latest edition. The Contractor and SWPPP Coordinator shall
obtain a current copy of MNDOT's Standard Specifications for Construction and familiarize themselves with the specification
sections applicable to this SWPPP, as there are several BMPs that specifically reference these sections.
The Contractor and SWPPP Coordinator shall be expected to be familiar with the applicable MNDOT specification sections
during construction. No additional compensation will be paid to the Contractor for additional work due to unfamiliarity with
these specification sections.
Temporary and Permanent Stabilization
All exposed soil areas (including stockpiles) shall be provided with temporary or permanent cover within 14 days of construction
activity temporarily or permanently ceasing in that portion of the site. Temporary or permanent drainage ditches or swales,
which drain off-site or to a surface water, and are within 200 lineal feet of the property line or surface water shall be provided
with temporary or permanent cover within 24 hours of construction. Placement of temporary or permanent cover shall be
initiated immediately upon suspension or completion of excavation operations.
Temporary Cover:
If the Contractor chooses to halt grading operations in a portion of the site (or the whole site) for a period exceeding 14 days,
and grading operations (rough or finish grading) in the affected areas has not yet been completed, temporary cover shall be
placed. Affected areas consisting of drainage ditches or swales connected to, and within, 200 lineal feet of a property line or
surface water shall be provided with temporary cover within 24 hours of connection. Depending on the Contractor's schedule,
the temporary cover shall consist of one of the following BMPs:
1). Discanchored Mulch
a). Discanchored mulch may be used in an area of the site (or the whole site) if the Contractor is halting grading operations
for a period that is relatively short, but exceeds 14 days.
b). The mulch shall be Type 3 per MNDOT Spec. 3882
c). An adequate quantity of mulch shall be evenly distributed to achieve 90% coverage of the exposed soils.
d). Mulch shall be placed as per MNDOT 2575.3F.
e). All mulch shall be disc anchored as per MNDOT 2575.3G. Prior to the placement and discanchoring of the mulch, the
soils shall be loosened and the area smooth-rough graded per MNDOT 2575.3B1.
f). Any areas that are exposed as a result of wind action after the initial mulch placement shall be covered with additional
mulch to maintain 90% coverage.
2). Temporary Seeding with Mulch
a). Temporary seeding with mulch may be used in areas of the site (or the whole site) if the Contractor is halting grading
operations for a period that is relatively long. Although mulch still needs to be applied as described above, once the
temporary seeding/turf is established, the mulch will no longer need to be maintained. The temporary seeding/turf will
require very little maintenance.
b). Prior to the sowing of temporary seed, the soils shall be loosened and the area smooth-rough graded per MNDOT 2575.3B1.
c). Contractor shall utilize Seed Mixes 100, 110, or 130 per MNDOT Spec. 3876 for temporary seeding.
d). Temporary seeding shall be sown per MNDOT Spec. 2575.3D.
e). Once temporary seeding has been sown, mulch shall be placed over the area as described above.
Permanent Cover:
Upon completion of finish grading and/or placement of topsoil, initiation of the placement of permanent cover shall begin
immediately over all exposed areas. This includes areas designated for impervious surfacing (ie: buildings, pavements/gravel
bases, sidewalks, etc.). Where the construction schedule will not allow for the placement of the permanent impervious surfacing
within 14 days of the completion of finish grading, temporary cover shall be provided in these areas, as described above, until
the permanent impervious surfacing can be constructed. Affected areas consisting of drainage ditches or swales connected
to, and within, 200 lineal feet of a property line or surface water, shall be provided with permanent cover within 24 hours of
connection.
Undisturbed Areas
If shown on the plan, the Contractor shall delineate areas that are not to be disturbed on the site. This may be done with flags,
stakes, signs, silt fence, etc., and shall be completed prior to the start of any grading operations. Regardless of the delineation
method the Contractor chooses to use, the Contractor must communicate to his/her personnel and subcontractors that these
areas are not to be disturbed and construction equipment (including trucks and personal vehicles) shall not be allowed in these
areas.
The Contractor shall minimize compaction and preserve topsoil as much as possible at the site. In pervious ("green") areas that
are not essential to the construction of the project, the Contractor shall avoid construction traffic and maintain the existing
condition of these areas.
2). Erosion Control Blanket
a). Erosion control blanket shall be placed in areas as shown on the plan included in this SWPPP. These areas shall still be
provided with permanent seeding, as described above, beneath the erosion control blanket.
b). Erosion control blanket shall meet the requirements indicated in MNDOT Spec. 3885. See plan for category(s) of erosion
control blanket.
c). Erosion control blanket shall be installed as per MNDOT Spec. 2575.3J2.
d). Erosion control blanket specified in drainage ditches and swales connected to, and within 200 lineal feet, of a property
line or surface water shall be installed within 24 hours of the completion of finish grading (including permanent seeding).
3). Riprap
a). Riprap shall be placed in areas as shown on the plan included in this SWPPP.
b). All riprap shall be underlain with Type 4 geotextile fabric. The fabric shall meet the requirements of MNDOT Spec. 3733 and
shall be installed as per MNDOT Spec. 2511.3B2.
c). Riprap materials shall meet the requirements of MNDOT Spec. 3601, and shall be Class 3, unless noted otherwise on the
plans.
d). Riprap shall be considered "Random Riprap" and shall be placed as per MNDOT Spec. 2511.
e). Although it is permitted for the riprap to be placed with machinery, it will be necessary for the Contractor to hand place
some of the riprap in order to provide a dense, well-keyed layer of stones with the least practical quantity of void space.
f). The minimum thickness of the riprap shall be 18 inches, unless otherwise noted on the plans.
g). Riprap designated at the end of pipe outlets shall be placed within 24 hours of installation of the pipe outlet end section.
h). Riprap specified in drainage ditches and swales connected to, and within 200 lineal feet, of a property line or surface
water shall be installed within 24 hours of the completion of finish grading.
Sediment Control
The following sediment control BMPs shall be implemented as part of this project:
1). Silt Fence
a). Silt fence shall be installed at the locations shown on the plan included in this SWPPP.
b). Silt fence shall be machine sliced and materials shall meet the requirements of MNDOT Spec. 3886.
c). Silt fence shall be installed as per MNDOT Spec. 2573.3C1.
d). Silt fence shall be installed prior to any upgradient grading operations, and shall remain in place and maintained
adequately until upgradient areas achieve Final Stabilization (see below)
2). Catch Basin Protection
a). WIMCO Road Drain protection devices, as manufactured by WIMCO, shall be used for catch basin protection on this
project. WIMCO can be contacted at (952)-233-3055, and their web page is www.roaddrain.com.
b). "Road Drain Top Slab" devices shall be installed at all catch basin locations immediately after placement of the catch
basin structures. "Road Drain Top Slab" devices shall remain in place and be adequately maintained until permanent
surfacing is constructed (ie: curb and gutter, pavements, and/or gravel surfacing). In areas designated for turf
establishment, "Road Drain Top Slab" devices shall remain in place until Final Stabilization of all upgradient areas is
established.
c). Upon construction of the permanent surfacing, the "Road Drain Top Slab" devices shall be replaced with the WIMCO
product specified on the plans. The WIMCO devices shall remain in place until Final Stabilization of all upgradient areas has
been established.
d). The contractor shall install and maintain the catch basin protection devices as per the manufacturer's instructions and
specifications.
3). Culvert Inlet Protection
a). Culvert inlet protection shall be provided at all culvert inlet locations immediately after construction of the culvert. See
plan included in this SWPPP for culvert inlet locations.
b). Culvert inlet protection shall consist of geotextile fabric wrapped around, and completely covering the inlet end section.
The geotextile fabric shall be the same fabric used in silt fence applications and meet the requirements of MNDOT Spec.
3886.
c). The culvert inlet protection shall remain in place and adequately maintained until Final Stabilization of all upgradient
areas has been established.
d). Culvert inlet protection shall be repaired or replaced if damaged during, or after, rain events, or if accumulated sediment
reaches 1/2 of the diameter of the culvert pipe. Repair or replacement of culvert inlet protection shall be completed within
24 hours of discovery.
4). Temporary Rock Construction Entrance
a). Temporary rock construction entrances shall be installed at the locations shown on the plan included in this SWPPP. See
detail for temporary rock entrance design.
b). If the Contractor chooses to access the site from locations other than where temporary rock entrances are specified on
the plans, additional temporary rock entrances shall be placed at these locations, as well.
c). Temporary rock entrance shall be constructed prior to the start of grading operations, and shall remain in place and be
adequately maintained until Final Stabilization has been established.
d). Temporary rock entrances shall be maintained in such a manner that the entrances prevent sediment tracking onto
adjacent streets. If a temporary rock entrance is found to be ineffective, it shall be replaced or improved within 24 hours of
discovery.
e). The Contractor has the option to place Type 4 geotextile fabric beneath the temporary rock entrance. The fabric may
extend the life of the entrance as it will reduce rock "sinking" into the underlying soils. If the Contractor chooses to use
fabric, it should meet the requirements of MNDOT Spec. 3733 and shall be installed as per MNDOT Spec. 2511.3B2.
f). If sediment tracking from the site is discovered on adjacent streets, the sediment shall be removed with a street sweeper or
other approved method within 24 hours of discovery. This shall be done throughout construction of the project. This
sediment may be returned and graded over exposed areas of the site, or disposed of off site per MPCA requirements.
The City may order street sweeping to be performed at the Contractor's or Owner's expense if City staff find that
construction activities are resulting in sediment or debris being tracked onto City streets.
5). Filter Logs
a). Filter logs shall be installed at the locations shown on the plan included in this SWPPP.
b). Filter logs shall consist of Type Wood Fiber biorolls and meet the requirements of MNDOT Spec.
3897.
c). Filter logs shall be installed as per MNDOT Spec. 2573.3J.
d). Filter logs shall be installed immediately after placement of erosion control blanket.
e). Filter logs shall remain in place for the life of the project, and shall be allowed to degrade
naturally.
g). Temporary soil stockpiles shall be placed on the site in areas upgradient from silt fence. Where the Contractor chooses to
place temporary soil stockpiles outside designated silt fenced areas, the stockpiles shall be surrounded by additional silt
fence. Under no circumstances shall temporary soil stockpiles be placed over surface waters, curb and gutter, catch basins,
culvert inlets or outlets, or ditches.
Dewatering
If dewatering of sandy subsoils is required for this project, the pump discharge shall be treated prior to
discharge off-site or into a surface water. Treatment of discharge shall be achieved with the use of a
"Dandy Dewatering Bag" (or approved equivalent), as manufactured by Dandy Products,Inc. Dandy
Products, Inc. can be contacted at (877) 307-0141, and their web page is www.dandyproducts.com.
The "Dandy Dewatering Bag" shall be installed, utilized, and maintained per the manufacturer's
instructions and specifications.
Once dewatering water has been treated, it may be discharged off-site or to a surface water. The
discharge shall be visually checked to ensure that it is relatively clean and not visibly different from any
receiving waters. If discharge is noticeably "dirty", the Engineer shall be contacted as additional
treatment methods may be necessary.
Adequate erosion control shall be provided at the point of discharge if it is located in an area with
exposed soils or established turf. This erosion control may consist of temporarily placed rip rap, or other
approved energy dissipation measures. The type of erosion control measure shall be at the
Contractor's discretion, depending on the location of the dewatering discharge and the unique site
characteristics. The erosion control measures shall be effective and shall be maintained adequately
such that no erosion occurs at the point of discharge.
Pollution Prevention Management
Solid waste accumulated during construction, including collected sediment, construction materials,
floating debris, construction debris, paper, plastics, and other solid wastes shall be disposed of in
accordance with MPCA disposal requirements:
1). Building products that have the potential to leach pollutants shall be maintained under cover
(e.g., plastic sheeting or temporary roofs) to prevent the discharge of pollutants or protected by a
similarly effective means designed to minimize contact with storm water.
2). Pesticides, herbicides, insecticides, fertilizers, treatment chemicals, and landscape materials shall
be maintained under cover (e.g., plastic sheeting or temporary roofs) to prevent the discharge of
pollutants or protected by similarly effective means designed to minimize contact with stormwater.
3). Hazardous materials, toxic waste, (including oil, diesel fuel, gasoline, hydraulic fluids, paint solvents,
petroleum-based products, wood preservatives, additives, curing compounds, and acids) shall be
properly stored in sealed containers to prevent spills, leaks or other discharge. Restricted access
storage areas shall be provided to prevent vandalism. Storage and disposal of hazardous waste or
hazardous materials shall be in compliance with Minn. R. ch. 7045 including secondary
containment as applicable.
4). Solid waste shall be stored, collected and disposed of properly in compliance with Minn. R. ch.
7035.
5). Portable toilets shall be positioned so that they are secure and will not be tipped or knocked over.
Sanitary waste must be disposed of properly in accordance with Minn. R. ch. 7041.
The Contractor shall take steps to prevent the discharge of spilled or leaked chemicals, including fuel,
from any area where chemicals or fuel will be loaded or unloaded including the use of drip pans or
absorbents unless infeasible. The Contractor shall conduct fueling in a contained area unless
infeasible. The Contractor shall ensure adequate supplies are available at all times to clean up
discharged materials and that an appropriate disposal method is available for recovered spilled
PDWHULDOV7KH&RQWUDFWRUVKDOOUHSRUWDQGFOHDQXSVSLOOVLPPHGLDWHO\DVUHTXLUHGE\0LQQ6WDW
115.061, using dry clean up measures where possible.
If the Contractor washes the exterior of vehicles or equipment on the project site, washing shall be
limited to a defined area of the site. Runoff from the washing area shall be contained in a sediment
basin or other similarly effective controls and waste from the washing activity shall be properly
disposed of. The Contractor shall properly use and store soaps, detergents, or solvents. No engine
degreasing shall be allowed on site.
The Contractor shall provide effective containment for all liquid and solid wastes generated by
washout operations (concrete, stucco, paint, form release oils, curing compounds and other
construction materials) related to the construction activity. The liquid and solid washout wastes shall
not contact the ground, and the containment shall be designed so that it does not result in runoff
from the washout operations or areas. Liquid and solid wastes shall be disposed of properly and in
compliance with MPCA rules. A sign must be installed adjacent to each washout facility that requires
site personnel to utilize the proper facilities for disposal of concrete and other washout wastes.
FINAL STABILIZATION
Final Stabilization shall be considered established once the following requirements have been achieved:
1). All soil disturbing activities at the site have been completed and all soils are stabilized by a uniform
perennial vegetative cover with a density of 70 percent of its expected final growth density over the entire
pervious surface area, or other equivalent means necessary to prevent soil failure under erosive conditions.
2). The permanent storm water management system is constructed, and is operating as designed.
Temporary or permanent sedimentation basins that are to be used as permanent water quality
management basins have been cleaned of any accumulated sediment. All sediment has been removed
from conveyance systems and ditches are stabilized with permanent cover.
3). All temporary synthetic and structural erosion prevention and sediment control BMPs have been
removed from the project site. BMPs designed to decompose on site may be left in place.
e). Silt fence shall be repaired or replaced if damaged during, or after, rain events, or if accumulated sediment on the
upstream side of the fence reaches 1/3 of the height of the fence. Repair or replacement of silt fence shall be completed
within 24 hours of discovery.
f). Portions of silt fence may be removed to accommodate short-term activities, such as vehicle passage. Short-term activities
shall be completed as quickly as possible, and new silt fence installed immediately after completion of the short-term
activity. If rainfall is imminent or forecasted in the near future, new silt shall be installed regardless of if the short term activity
has been completed or not. The Contractor is advised to schedule short term activities during dry weather as much as
practicable. No additional compensation will be paid due to additional silt fence associated with short-term activities.
Areas designated for permanent turf establishment shall be provided with one or more of the following BMPs (see plan):
1). Permanent Seeding with Mulch
a). Unless otherwise noted on the plans, all areas designated for turf establishment shall be provided with permanent seeding.
b). In addition to the plan included as part of this SWPPP, the Contractor shall verify if a Landscaping Plan has been included
in the plans by the Architect. If a Landscape Architect has specified higher quality permanent cover (ie: sod, hydroseeding,
etc.), the Contractor shall provide this permanent cover in lieu of the permanent seeding specified in this SWPPP.
c). Prior to the sowing of permanent seed, the soils shall be loosened and the area smooth-rough graded per MNDOT
2575.3B1.
d). Contractor shall utilize Seed Mix 260 per MNDOT Spec. 3876 for permanent seeding.
