General Construction Project Information

Describe the construction activity (what will be built, general timeline, etc):

Bridge Replacement, Retaining Walls, Grading, Bituminous Pavement, Curb & Gutter, Storm Sewer and Sanitary Sewer.

Construction starts June 2012 and opens to traffic by October 31, 2012.

Describe soil types found at the project: See bridge plan.

General Site Information (III.A)


wq-strm2-12 • 4/13/09 Page 3 of 8

1. Describe the location and type of all temporary and permanent erosion prevention and sediment control Best Management Practices (BMPs). Include the timing for installation and procedures used to establish additional temporary BMPs as necessary. (III.A.4.a)

This project drains into Forest Lake Channel.

See the most current Construction Plan, Specification and Addendum. The Contractor must prepare a Site Management Plan (see Specifications) that address sources of pollution such as concrete dust, debris, etc. that are not covered by this SWPPP prior to mobilization.

See Construction Plan, Turf & Drainage Plan, and Erosion Control Plan (attached in Appendix B) for the location and type of BMPs. Also, refer to the Erosion Control, Turf Notes & Details sheets and the Specifications for information on the temporary and permanent BMPs.

The erosion prevention and sediment control BMPs include: rock construction entrance for the work on each side of the Channel and should be placed at all site access points where storm water runs away from the construction site, heavy duty silt fences along portions of the project, biorolls, flotation silt curtains in the Channel, rapid stabilization for all disturbed areas adjacent to the Channel, and inlet protection devices for all inlets in the project area. The location, limits and quantity may be modified by the Contractor with approval by the Engineer.

Install silt fence, flotation silt curtain and inlet protection prior to commencement of any activities. Install the rock construction entrance as soon as the existing pavement has been removed. Place Rapid Stabilization as soon as grading activities have ceased.

When an area has been disturbed and graded, temporary seeding must occur within seven days of the completion of the grading. Permanent sodding or seeding stabilization must be completed within seven days after final grading and topsoil placement. After final stabilization, all temporary erosion prevention and sediment control BMPs must be removed and accumulated sediment must be removed.

Permanent BMPs on the site include turf establishment, three sump manholes, two vegetated ditches, salt and sand application reduction during ice and snow removal, street sweeping in the spring and as needed during the summer and fall, and litter control with the Adopt-A-Highway program.

2. Attach to this SWPPP a table with the anticipated quantities for the life of the project for all erosion prevention and sediment control BMPs (III. A. 4.b)

See sheet 2, Estimated Quantities (Appendix B) with the anticipated items 2573.XXX to 2575.XXX and quantities.

3. Attach to this SWPPP a site map that includes the following features (III.A.3.b – f):

Existing and final grades, including dividing lines and direction of flow for all pre and post-construction stormwater runoff drainage areas located within the project limits.

Locations of impervious surfaces and soil types.

Locations of areas not to be disturbed.

Location of areas of phased construction

All surface waters and existing wetlands within one mile from the project boundaries that will receive stormwater runoff from the site (identifiable on maps such as USGS 7.5 minute quadrangle maps or equivalent). Where surface waters receiving runoff associated with construction activity will not fit on the plan sheet, they must be identified with an arrow, indicating both direction and distance to the surface water.

Methods to be used for final stabilization of all exposed soil areas.

See Appendix B for the following: Title Sheet, Earthwork Summary and Standard Plates, Typical Sections, Removal Plan, Construction Plan, Turf & Drainage Plan, Erosion Control, Turf Notes & Details, and Erosion Control Plan.

4. Were stormwater mitigation measures required as the result of an environmental, archaeological, or other required local, state, or federal review of the project? Yes No

If yes, describe how these measures were addressed in the SWPPP. (III.A.6.)

5. Is the project located in a karst area such that additional measures would be necessary to protect drinking water supply management areas as described in Minn. R. chapters 7050 and 7060? Yes No

If yes, describe the additional measures to be used. (III.A.7.)

6. Does the site discharge to a calcareous fen listed in Minn. R. 7050.0180, subp. 6.b.? Yes No

If yes, a letter of approval from the Minnesota Department of Natural Resources must be obtained prior to application for this permit. (Part I B.6 and Part III.A.8)

7. Does the site discharge to a water that is listed as impaired for the following pollutant(s) or stressor(s): phosphorus, turbidity,


wq-strm2-12 • 4/13/09 Page 4 of 8

dissolved oxygen or biotic impairment? Use the Special and Impaired Waters Search Tool at: www.pca.state.mn.us/water/stormwater/stormwater-c.html. Yes No

If no, skip to Training.

Does the impaired water have an approved Total Maximum Daily Loads (TMDL) with an Approved Waste Load Allocation for construction activity? Yes No

If yes:

a. List the receiving water, the areas of the site discharging to it, and the pollutant(s) identified in the TMDL.

b. List the BMPs and any other specific construction stormwater related implementation activities identified in the TMDL.

If the site has a discharge point within one mile of the impaired water and the water flows to the impaired water but no specific BMPs for construction are identified in the TMDL, the additional BMPs in Appendix A (C.1 and C.2) must be added to the SWPPP and implemented. (III.A.7). The additional BMPs only apply to those portions of the project that drain to one of the identified discharge points.

Two sump manholes with two ditches will provide water quality. The net increase in impervious is 0.15 acres. Right of way is not available to provide any other treatment. There are also constraints with the closeness of Forest Lake Channel and floodplain.

Training (III.A)

Training is required for all permitted projects after February 1, 2010. It must be provided by entities with expertise in erosion prevention, sediment control or permanent stormwater management. Training must be focused on the individual’s job duties as they relate to the permit requirements (Part III.A.2). Who must be trained?

Individual(s) preparing the SWPPP for the project Individual(s) overseeing the implementation of, revising and amending the SWPPP and individuals performing

inspections required by the permit Individuals performing or supervising the installation, maintenance or repair of BMPs

Selection of a Permanent Stormwater Management System (III.C)

1. Will the project create a new cumulative impervious surface greater than or equal to one acre? Yes No

New impervious surface is 0.15 acre

If yes, a water quality volume of one-half inch of runoff from this area must be treated before leaving the site or entering surface waters (one inch if discharging to special waters).

2. Describe which method will be used to treat runoff from the new impervious surfaces created by the project (III.C):

Wet sedimentation basin

Infiltration/Filtration

Regional ponds

Combination of practices

Include all calculations and design information for the method selected. See Part III.C of the permit for specific requirements associated with each method.

Not applicable

http://www.pca.state.mn.us/water/stormwater/stormwater-c.html


wq-strm2-12 • 4/13/09 Page 5 of 8

3. If it is not feasible to meet the treatment requirement for the water quality volume, describe why. This can include proximity to bedrock or road projects where the lack of right of way precludes the installation of any permanent stormwater management practices. Describe what other treatment, such as grasses swales, smaller ponds, or grit chambers, will be implemented to treat runoff prior to discharge to surface waters. (III.C)

Not applicable

4. If proposing an alternative method to treat runoff from the new impervious surfaces, describe how this alternative will achieve approximately 80 percent removal of total suspended solids on an annual average basis (III.C.5).

Note: If proposing an alternative method, you must submit your SWPPP to MPCA at least 90 days prior to the starting date of

the construction activity.

Not applicable

Erosion Prevention Practices (IV.B)

1. Describe construction phasing, vegetative buffer strips, horizontal slope grading, and other construction practices to minimize erosion. Delineate areas not to be disturbed (e.g., with flags, stakes, signs, silt fence, etc.) before work begins.

See the Construction Plan for the Construction, Superelevation and Drainage Plan sheets that have the construction limits. The Erosion Control sheets have the location of silt fence, sodding, seeding, temporary rock construction entrance, rip rap, inlet protection, etc.

Install silt fence, flotation silt curtain and inlet protection prior to commencement of any activities. Install the rock construction entrances as soon as the existing pavement has been removed. Place Rapid Stabilization s soon as grading activities have ceased.

2. Describe temporary erosion protection or permanent cover used for exposed soil. All exposed soil areas must be stabilized as soon as possible but in no case later than 14 days after the construction activity in that portion of the site has temporarily or permanently (part IV.B.2).

When an area has been disturbed and graded, temporary seeding must occur within seven days of the completion of the grading. Permanent sodding stabilization must be completed within seven days after final grading and topsoil placement.

3. For drainage or diversion ditches, describe practices to stabilize the normal wetted perimeter within 200 lineal feet of the property edge or point of discharge to surface water. The remaining portions of the temporary or permanent ditch or swale must be stabilized within 14 days after connecting to surface waters and construction in that portion of the ditch has temporarily or permanently ceased.

There are two existing drainage ditchs on this project. The first ditch is on the south side of the road and west of Forest Lake Channel. The second ditch is on the north side of the road and east of Forest Lake Channel. This project will have erosion blankets on all ditch bottoms within 200’ of Forest Lake Channel. Erosion blankets will also be needed on disturbed areas within 100’ of Forest Lake Channel. The Erosion Control plan also calls for flotation silt curtain, silt fence, rip rap, sodding, erosion control blanket, rapid stabilization, and biorolls. Disturbed areas adjacent to Forest Lake Channel must be stabilized immediately after grading operations cease.

4. Describe other erosion prevention practices (list and describe).

See previous


wq-strm2-12 • 4/13/09 Page 6 of 8

Sediment Control Practices (IV.C)

Describe sediment control practices used to minimize sediments from entering surface waters, including curb and gutter systems and storm drain inlets. At a minimum, these sediment control practices must include:

Sediment controls for temporary or permanent drainage ditches and sediment basins that are designed as part of a treatment system

Installation of check dams or other grade control practice to ensure sheet flow and prevent rills (for slope lengths greater than 75 feet with a grade of 3:1 or steeper).

Sediment control practices on all down gradient perimeters prior to land disturbing activities.

Storm drain inlet protection for all inlets.

Silt fencing or other sediment control surrounding temporary soil stockpiles.

Minimize vehicle tracking of sediments (e.g., stone pads, concrete or steel wash racks, or equivalent systems).

Street sweeping of tracked sediment.

Temporary sedimentation basins (see Part III.B).

The Contractor’s Erosion Control Supervisor shall implement any process for containment necessary to minimize sediment transport, which may include controls in addition to those listed in this document.

Inlet protection and sediment control devices will be placed prior to or concurrent with any up gradient disturbance.

Sediment control devices shall be provided and maintained at all times throughout construction.

Bioroll shall be installed around stockpiles or erodible materials prior to stockpiling.

Rough grading should be as smooth as possible to allow sheet flow of storm water whenever practical and allow placement of erosion control blankets if necessary.

Sediment reaching a public or private road shall be removed by street sweeping before the end of each workday.

Dewatering and Basin Draining (IV.D)

1. Will the project include dewatering or basin draining? Yes No

2. If yes, describe BMPs used so the discharge does not adversely affect the receiving water or downstream landowners.

Temporary dewatering should be necessary at the bridge and sanitary jacking pit. Any dewatering must be pumped to a temporary sediment basin or other BMP to remove sediment from the discharge water. The discharge water must have adequate energy dissipation and not adversely affect the receiving water or downstream landowners. In accordance to Mn/DOT specifications 2451.3C, the Contractor shall, at no expense to the Department, provide temporary construction, pumping or other means to the extent necessary to permit construction in a dry excavation. In accordance to Mn/DOT specifications 2573.3 A4, the Contractor shall submit a dewatering plan to the Engineer prior to initiating dewatering activities.

Additional BMPs for Special Waters and Discharges to Wetlands (Appendix A, Parts C and D)

1. Special Waters. Does your project discharge to special waters? Yes No

2. If proximity to bedrock or road projects where the lack of right of way precludes the installation of any of the permanent stormwater management practices, then other treatment such as grassed swales, smaller ponds, or grit chambers is required prior to discharge to surface waters. Describe what other treatment will be provided.

Not applicable

3. Describe erosion and sediment controls for exposed soil areas with a continuous positive slope to a special waters, and temporary sediment basins for areas that drain five or more acres disturbed at one time.

Not applicable

4. Describe the undisturbed buffer zone to be used (not less than 100 linear feet from the special water).

Not applicable

5. Describe how the permanent stormwater management system will ensure that the pre and post project runoff rate and volume from the 1, and 2-year 24-hour precipitation events remains the same.

Not applicable


wq-strm2-12 • 4/13/09 Page 7 of 8

6. Describe how the permanent stormwater management system will minimize any increase in the temperature of trout stream receiving waters resulting in the 1, and 2-year 24-hour precipitation events.

Not applicable

7. Wetlands. Does your project discharge stormwater with the potential for significant adverse impacts to a wetland (e.g.,

conversion of a natural wetland to a stormwater pond)? Yes No

If Yes, describe the wetland mitigation sequence that will be followed in accordance with Part D of Appendix A.

Not applicable

.

Inspections and Maintenance (IV.E)

Describe procedures to routinely inspect the construction site:

Once every seven (7) days during active construction and,

The Contractor will be responsible for daily visual inspections of all cleared and graded areas of the construction site. Formal inspections of areas under construction will be done once per week and within 24 hours of the end of a storm with rainfall amounts greater than 0.5 inches in 24 hours. Any sediment that escapes the construction site will be removed immediately.

Pollution Prevention Management Measures (IV.F)

1. Describe practices to properly manage and dispose of solid waste, including trash (IV.F.1):

Non-hazardous waste materials will be collected and stored in a securely lidded metal dumpster or other approved containment method at the end of the day. All trash and construction debris from the site will be deposited in the dumpster.

2. Described practices to properly manage hazardous materials (IV.F.2):

The Contractor must have an established protocol for the storage and disposal of hazardous materials. The protocol must comply with MPCA disposal regulations. Access restrictions to storage areas must be in place to prevent vandalism. Hazardous Materials items may include: oil, gasoline, paint or other hazardous substances. Any possible releases require Hennepin County to notify regulatory authorities and emergency personnel pursuant to federal, state, and local laws. See Appendix C for a list of pollutants that result from clearing, grading, excavation, bridge demolition and road building and have the potential to be present in storm water runoff. This table includes information regarding material type, chemical and physical description, and the specific regulated storm water pollutants associated with each material.

3. Describe practices for external washing of trucks and other construction vehicles (IV.F.3):

The Contractor will establish an area where all washing of trucks or other construction equipment must take place to ensure that the runoff is contained and the waste is disposed of in a proper manner. No engine degreasing will be allowed on site.

Only clean equipment is allowed on site and the equipment must be clean before leaving the site.

4. Describe how are you going to provide a safe, lake proof, concrete washout on site (IV.F.4):

Concrete trucks will not be allowed to wash out or discharge surplus concrete or drum wash water on the site, unless done at designated sites or in an engineered containment system.

5. Describe your spill prevention plan:

Good housekeeping and spill control practices will be followed during construction to minimize storm water contamination from petroleum products, fertilizers, paints and concrete.


wq-strm2-12 • 4/13/09 Page 8 of 8
