Provide dewatering systems as required for excavations. Dewatering shall be done in accordance with any applicable federal, state and municipal requirements and the Contractor shall be responsible for any permits required. 2. Design and provide dewatering system using accepted and professional methods consistent with current industry practice to eliminate water entering the excavation under hydrostatic head from the bottom or sides. Design system to prevent differential hydrostatic head, which would result in floating out soil particles in a manner, termed as a "quick" or "boiling" condition. System shall not be dependent solely upon sumps or pumping water from within the excavation where differential head would result in a quick condition, which would continue to worsen the integrity of the excavation's stability. 3. Provide dewatering system of sufficient size and capacity to prevent ground and surface water flow into the excavation and to allow Work to be installed in a dry condition. 4. Control, by acceptable means, all water regardless of source. Contractor shall be responsible for disposal of the water. 5. Confine discharge piping or ditches to available easement or to additional easement obtained by Contractor. Provide necessary permits or easement. 6. Control groundwater in a manner that preserves strength of foundation soils, does not cause instability or raveling of excavation slopes, and does not result in damage to existing structures. Where necessary, lower water level in advance of excavation utilizing wells, wellpoints, jet eductors, or similar positive methods. The water level shall be maintained a minimum of 3 feet below prevailing excavation level. 7. Commence dewatering prior to any appearance of water in excavation and continue until Work is complete to the extent that no damage results from hydrostatic pressure, flotation, or other causes. 8. Open pumping with sumps and ditches will be allowed provided it does not result in boils, loss of fines, softening of the ground, or instability of slopes. 02300 -5 Wal -Mart Expansion Store No. 1861 -01, Oak Park Heights, Minnesota 07/20/05 9. Install wells or wellpoints, if required, with suitable screens and filters so that continuous pumping of fines does not occur. Arrange discharge to facilitate collection of samples by the Owner. During normal pumping and upon development of wells, levels of fine sand or silt in the discharge water shall not exceed 5 ppm. Install sand tester on discharge of each pump during testing to verify that levels are not exceeded. 10. Control grading around excavations to prevent surface water from flowing into excavation areas. 11. No additional payment will be made for any supplemental measures to control seepage, groundwater, or artesian head. B. Design: 1. Designate and obtain the services of a qualified dewatering specialist to provide dewatering plan as may be necessary to complete the Work. 2. Contractor shall be responsible for the accuracy of the drawings, design data, and operational records required. 3. Contractor shall be responsible for the design, installation, operation, maintenance, and any failure of any component of the system. C. Damages: 1. Contractor shall be responsible for and shall repair any damage to work in place, other contractor's equipment, utilities, residences, highways, roads, railroads, private and municipal well systems, adjacent structures, natural resources, habitat, existing wells, and the excavation. Contractor responsibility shall also include, damage to the bottom due to heave and including but not limited to, removal and pumping out of the excavated area that may result from Contractor's negligence, inadequate or improper design and operation of the dewatering system, and any mechanical or electrical failure of the dewatering system. 2. Remove subgrade materials rendered unsatisfactory by excessive wetting and replace with approved backfill material at no additional cost to the Owner. D.

This SWPPP, including the applicable General Permit, includes the elements necessary to comply with the national General Pennit for construction activities administered by the U.S. Environmental Protection Agency (EPA) and the Minnesota Pollution Control Agency under the National Pollutant Discharge Elimination System (NPDES) /State Disposal System (SDS) program and all local governing agency requirements. This SWPPP must be implemented at the start of construction. Construction phase pollutant sources anticipated at the site are disturbed (bare) soil, vehicle fuels and lubricants, chemicals and coatings associated with site or building construction and pavement installation, construction - generated litter and debris, and building materials. Without adequate control there is the potential for each type of pollutant to be transported by storm water. Project construction will consist primarily of site grading, paving, stone drainage, water supply, sewage collection, and site lighting to facilitate construction of: The expansion of an existing Wal -Mart Store (97,750 square feet) to a Wal-Mart Supercenter (224,874 square feet total) on a 23.96 -acre site. A. Purpose B. Scope A major goal of pollution prevention efforts during project construction is to control soil and pollutants that originate on the site and prevent them from flowing to surface waters. The purpose of this SWPPP is to provide guidelines for achieving that goal. A successful pollution prevention program also relies upon careful inspection and adjustments during the construction process in order to enhance its effectiveness. This SWPPP must be implemented before construction begins on the site. It primarily addresses the impact of storm rainfall and runoff on areas of the ground surface disturbed during the construction process. In addition, there are recommendations for controlling other sources of pollution that could accompany the major construction activities. This SWPPP will terminate when disturbed areas are stabilized, permanent erosion and sedimentation controls installed, temporary erosion and sedimentation controls removed, construction activities covered herein have ceased, and a completed Notice of Termination (NOT) is mailed to the governing agency. Forms which are necessary for implementing the SWPPP are included herein. The national General Permit for Storm Water Discharges Associated with Construction Activities prohibits most non -storm water discharges during the construction phase. Allowable water discharges that could occur during construction on this project are those discharges set forth and covered by the General Permit. 02370 -10 WaI --Mart Expansion Store No. 1861-04, Oak Park Heights, Minnesota Date: July 1, 2005 Best Management Practices must be implemented for the allowable discharges for the duration of the permit, Each non -storm water discharge should be noted in the SWPPP and weekly inspection with the exception of discharges from fire fighting activities. The techniques described in this SWPPP focus on providing control of pollutant discharges with practical approaches that utilize readily available expertise, materials, and equipment. The Owner referred to in this SWPPP is Wal-Mart Real Estate Business Trust. The General Contractor shall construct the site development improvements while working under contract with the Owner. III. PROJECT DESCRIPTION Described below are the major construction activities that are the subject of this SWPPP. They are presented in the order (or sequence) they are expected to begin, but each activity will not necessarily be completed before the next begins. Also, these activities could occur in a different order if necessary to maintain adequate erosion and sedimentation control. All activities and the timeframe (beginning and ending dates) shall be noted on the Site Map and Record of Stabilization and Construction Activity Dates: A. Install stabilized construction exit. This will be the first construction work on the project. B. Install sediment barriers down slope from construction activities that disturb site soil as shown on plan; C. Construct rock surface for temporary parking and storage areas; D. Install inlet protection around all existing storm sewer structures; E. Construction of the sediment basins; F.

Remove all temporary erosion and sediment control devices only after site is stabilized. 02370 -11 Wal -Mart Expansion Store No. 1861 -04, Oak Park Heights, Minnesota Date: July 1, 2005 The actual schedule for implementing pollutant control measures will be determined by project construction progress and recorded by the General Contractor on the Soil Erosion /Sedimentation Control Operation Time Schedules on the Erosion & Sedimentation Control Plans (Site Map). Down slope protective measures must always be in place before soil is disturbed. Ive SITE DESCRIPTION Included as part of this SWPPP are the project Construction Drawings- Proposed Expansion to Wal -Mart Store # 1861 -04, 5815 Norell Avenue North, Oak Park Heights, Minnesota, Washington County. Refer to the Construction Drawings for detailed site information. A. Site Location - The Site consists of a 23.96 acre developed parcel at 5815 Norell Avenue North in Oak Park Heights, Washington County, Minnesota. The Site is bounded to the west by Norell Avenue and commercial sites, on the North by commercial sites and beyond Highway 36, on the east by undeveloped property zoned commercial and on the South by open land with institutional property beyond. The Site is at Latitude 45 01' 59.30" and Longitude 92° 49' 55.13 ". The receiving waters for both pre and post construction storm water discharge is the on -site storm sewer, which discharges to water quality ponds and discharges into the MNDOT ditch and then eventually into Menard's Pond. From there it goes north into Stillwater into a pond next to Target and eventually into Long Lake. None of these are Special Waters. A Vicinity Map is included in Appendix A. B. Site Topography - The Site is an existing commercial site. The existing topography generally slopes from building floor elevation 948.2 to storm inlets in the front (lowest inlet elevation in the parking lot is 938.5 near the northwest corner of the parking) and back of the building (lowest inlet elevation in the parking lot is 944.8). The highest point on the property is near the southeast corner at elevation 952.0. Present drainage is to the north and west. The existing vegetation includes landscaping for the commercial site with some grassland to the east. The topography will change with the construction of ponds in the southwest corner and some cut to the east to level the property for the expansion of the building and parking lot. The present drainage will remain flowing from southeast to northwest. C. Rainfall Information - The average total annual precipitation is about 29.58 inches. Of this about 19.18 inches, or 65 percent, usually falls in May through September. The average annual snowfall is 57.3 inches. D. Site Soils -- 40 penetration borings were performed by geotechnical firm. Eight of the borings were performed in the existing pavement areas and encountered about 4 to 5 inches of bituminous material over approximately 4 to 7 inches of aggregate base materials. Sixteen of the borings encountered about 4 to 8 inches of silty sand topsoil. Twenty -three of the borings encountered existing fill to depths of 2 to 9 feet, either initially from the surface or beneath the existing pavement. The existing fill consisted predominantly of silty sand, with lesser amounts of poorly graded sand, poorly graded sand with silt and clayey sand. Below the existing pavements, existing fill or topsoil, the borings encountered and terminated in naturally deposited soils. The naturally deposited soils encountered consisted of poorly graded sand, poorly graded sand with silt, silty sand, clayey sand, lean clay and silt. E. Total Area and Disturbed Area - The entire site contains 23.96 acres and the area to be disturbed by grading is anticipated to be approximately 17.33 acres. Pre - Construction Runoff Coefficient {or SCS TR -55 Curve Number]: "C" = 0.57 or CN = 82 Post - Construction Runoff Coefficient [or SCS TR -55 Curve Number] : "C" = 0.76 or CN = 91 F. Receiving Surface Waters and Wetlands - The receiving waters for both pre and post construction storm water discharge is the on -site storm sewer, which discharges to water quality ponds and discharges into the MNDOT ditch and then eventually into Menard's Pond. From there it goes north into Stillwater into a pond next to Target and eventually into Long Lake, approximately 1 mile west - northwest. None of these are Special Waters G.

H. Threatened and Endangered Species — There are no known threatened or endangered species on the site, according to the "Phase I Environmental Site Assessment" completed by Braun Intertec. 1. Historic Properties — There are no historic properties that will be impacted. Determined from site visits and verified on the National Register of Historic Places. V. STORM WATER POLLUTION PREVENTION MEASURES AND CONTROLS A variety of storm water pollutant controls are recommended for this project. Some controls are intended to function temporarily and will be used as needed for pollutant control during the construction period. These include temporary sediment barriers and permanent storm retention ponds (which can also function as permanent sediment basins). For most disturbed areas, permanent stabilization will be accomplished by covering the soil with pavement, building, or vegetation. A. Erosion and Sediment Controls 1. Soil Stabilization - The purpose of soil stabilization is to prevent soil from leaving the site. In the natural condition, soil is stabilized by native vegetation. The primary technique to be used at this project for stabilizing site soil will be to provide a protective cover of turf grass, pavement, or building structure. a) Temporary Seeding or Stabilization ----- Areas may be stabilized temporarily with the use of fast - germinating annual seed, straw mulch, wood cellulose fibers, tackifiers, netting or blankets. Where conditions are favorable, areas shall be temporarily stabilized within 14 days after construction activity ceases. All disturbed ground where there will not be construction for longer than 21 days must be seeded or otherwise stabilized. b C) Permanent Seeding or Sod -- All areas at final grade must be seeded or sodded within 14 days after completion of the major construction activity. Except for small level spots, seeded areas should generally be protected with mulch. All areas to be seeded will also have topsoil and other soil amendments as stated in Specification Section 02900 - Planting. All exposed soil areas with a continuous positive slope within 200 lineal feet of a surface water, must have temporary erosion protection or permanent cover for the exposed soil areas year round, according to the following table of slopes and time frames: * Maximum time an area can remain open when an area is not being worked. These areas include constructed storm water management pond side slopes, and any exposed soil areas with a positive slope to a storm water conveyance system, such as a curb and gutter system, storm sewer inlet, temporary or permanent drainage ditch or other natural or man made systems that discharge to a surface water. Temporary stockpiles without significant silt, clay or organic components (e.g., clean aggregate stockpiles, demolition concrete stockpiles, sand stockpiles) are exempt from this requirement but must comply with Part IV.C.5 of the general permit. 2. Structural Controls — Sheets C -2.0 "Phase I Erosion and Sedimentation Control Plant "Site Map "" shows proposed temporary sedimentation basin to trap sediment created by runoff from grading 02370 -13 Wal-Mart Expansion Store No. 1861-04, Oak Park Heights, Minnesota Date: July 1, 2005 activity along with the temporary stone construction exit, inlet protection, silt fence, temporary diversion ditch, limits of disturbance, temporary diversion dike, temporary stabilization measures, temporary storage and parking area and notes. Sheets C -2.1 "Phase II Erosion and Sedimentation Control Plan/ "Site Map "" shows the permanent seeding, inlet protection, temporary stone construction exit and silt fence. Sheet C -2.2 "Erosion and Sedimentation Control Notes and Details" shows the Site Location Map, USGS Quadrangle Map, general erosion control notes and details of inlet protection, rock construction exit, sediment control barrier and silt fence. a) Sediment Basins — Temporary & permanent sediment basins are depressions constructed downslope of construction activity and located such that storm water runoff from upland areas of less than 100 acres are diverted through the basin. Sediment basins shall be constructed as directed by the Storm Water Pollution Prevention Plan and shall be constructed as part of the initial best management practices whenever practical. Two permanent basins, which are connected by an equalizer pipe, will be used as temporary sediment basins during construction. They are designed for two different areas, including the south & east areas (runoff from 10.36 acres requiring a volume of 2.12 acre -feet) and the central area (runoff from 0.93 acres requiring a volume of 0.04 acre - feet). The central drainage area includes existing structures in the existing parking lot, as well as two new structures from the parking lot expansion to the east. Runoff from the central drainage area will continue to drain to the existing pond on the west side of Norell Avenue. Structures draining to this pond will be protected to prevent sediment from entering the existing pond. Temporary sediment pond capacities where checked using the runoff from a 2 -year 24 hour storm per Part III B of the General Permit (see Appendix J). Sediment basins shall be phased with the earthwork activity where practical. b C) d Sediment Traps -- Temporary sediment traps are depressions constructed downslope of construction activity and located such that storm water runoff from upland areas of less than 5 acres are diverted through the trap. Sediment traps shall be constructed as indicated by the Storm Water Pollution Prevention Plan and shall be constructed as part of the initial best management practices whenever practical. Traps are not used per this design. Traps if constructed as revisions to plans during construction, shall be designed with an overflow weir incorporated at the outlet to discharge flow from the trap. Sediment traps shall be phased with the earthwork activity where practical. Silt Fence — Silt fence is a synthetic permeable woven or non -woven fabric typically incorporating wooden or metal support stakes at intervals sufficient to support the fence, water and sediment retained by the fence. Silt fence can also be installed with a wire fence backing. The fence is designed to retain sediment -laden water and allow settlement of suspended soils before the storm water flows through the fabric for discharge downstream. Silt fence shall be located to capture overland, low- velocity sheet flows as follows: Silt Fence is to be placed as shown on the Phase I and Phase II Erosion and Sedimentation Control Plans. The fence is located so that not more than % acre of drainage area contributes runoff to 100 feet of wire reinforced silt fence. Install silt fence at a fairly level grade (along the contour) to provide sufficient upstream storage volume for the anticipated runoff. Drainage area shall not exceed 1/4 acre per 100 feet on non - reinforced silt fence, or %z acre per 100 feet of wire- reinforced silt fence for slopes less than 2 percent. In areas of steeper slopes or highly erodible soils, wire- reinforced silt fence shall be used. Construction Exit -- All access points from the public street into the construction site shall include a construction exit composed of coarse stone to the dimensions shown on the Construction Drawings. The rough texture of the stone helps to remove clumps of soil adhering to construction vehicle tires through the action of vibration and jarring over the rough surface and the friction of the stone matrix against soils attached to vehicle tires. e) Storm Sewer Inlet Protection -- Curb and grated inlets are protected from the intrusion of silt and sediment through a variety of measures as shown on the Construction Drawings. The primary mechanism is to place controls in the path of flow sufficient to slow sediment -laden water to allow settlement of suspended soils before discharging into the storm sewer. Grated inlets typically include a sturdy frame wrapped in silt fence or 02370 -14 Wal-Mart Expansion Store No. 1861 -04, Oak Park Heights, Minnesota Date: July 1, 2005 crushed stone -lined perimeter to slow the flow of water and allow ponding where sediment may settle out. Curb inlets typically include crushed stone barriers held in place with silt fence material or geotextile fabric. Other manufactured products are also available. f) Check Dam — Defined channels subject to concentrated flows in larger quantities and higher velocities may be protected with rock or other manufactured device check dams. The dams impound sediment -laden water to allow settlement of suspended soils before flowing over and through the device. Dams shall be placed along the water course at intervals as follows: Check dams shall be used in lieu of other forms of stabilization for the diversion ditches and shall be designed as shown on the plans (Sheet C -2.2 "Erosion and Sedimentation Control Notes and Details "). Check dams shall be placed as shown on the Construction Drawings and are composed of components of crushed stone and/or riprap or other manufactured device. g) Diversion DitchlBerm — Diversion ditches (or swales) and berms (or dikes) are constructed as shown on the Construction Drawings at locations within the construction site to intercept overland flow and direct or divert flow to a sediment basin or other point where discharge can be controlled. Ditches are excavated in the surface soils with the spoils from excavation typically placed along the downstream edge of the ditch to provide additional capacity. Berms are built up on the surface soils and compacted to create a stable diversion. Final site stabilization is achieved when turf grass cover provides permanent stabilization for at least 70 percent of the disturbed soil surface, exclusive of areas that have been paved. B. Other Pollutant Controls Control of sediments has been described previously. Other aspects of this SWPPP are listed below: 1. Dust Control - Construction traffic must enter and exit the site at the stabilized construction exit. The purpose is to trap dust and mud that would otherwise be carried off -site by construction traffic. Water trucks or other dust control agents 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 Wal-Mart Construction Manager, and in compliance with applicable local and state dust control regulations. After construction, the site will be stabilized (as described elsewhere), which will reduce the potential for dust generation. 2. Solid Waste Disposal - 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 as necessary by a contract trash disposal service and hauled away from the site. The location of solid waste receptacles shall be shown on the Erosion and Sedimentation Control Plan ( "Site Map "). Substances that have the potential for polluting surface and/or groundwater must be controlled by whatever means necessary in order to ensure that they do not discharge from the site. As an example, special care must be exercised during equipment fueling and servicing operations. If a spill occurs, it must be contained and disposed so that it will not flow from the site or enter groundwater, even if this requires removal, treatment, and disposal of soil. hi this regard, potentially polluting substances should be handled in a manner consistent with the impact they represent. 3. Sanitary Facilities - All personnel involved with construction activities must comply with state and local sanitary or septic system regulations. Temporary sanitary facilities will be provided at the site throughout the construction phase. They must be utilized by all construction personnel and will be serviced by a commercial operator. The location of sanitary facilities shall be shown on the Erosion and Sedimentation Control Plan ( "Site Map "). 02370-15 Wal -Mart Expansion Store No. 1861-04, Oak Park Heights, Minnesota Date: July 1, 2005 4. Water Source - Non -storm water components of site discharge must be clean water. Water used for construction which discharges from the site must originate from a public water supply or private well approved by the State Health Department. Water used for construction that does not originate from an approved public supply must not discharge from the site. It can be retained in the ponds until it infiltrates and evaporates. 5. Concrete Waste from Concrete Ready -Mix Trucks — Discharge of excess or waste concrete andlor wash water from concrete trucks will be allowed on the construction site, but only in specifically designated diked areas prepared to prevent contact between the concrete andlor wash water and storm water that will be discharged from the site. Alternatively, waste concrete can be placed into forms to make riprap or other useful concrete products. The cured residue from the concrete washout diked areas shall be disposed in accordance with applicable state and federal regulations. The jobsite superintendent is responsible for assuring that these procedures are followed. The location of concrete washout areas shall be shown on the Erosion and Sedimentation Plan ( "Site Map "). 6. Fuel Tanks -- Temporary on -site fuel tanks for construction vehicles shall meet all state and federal regulations. Tanks shall have approved spill containment with the capacity required by the applicable regulations. The tank shall be in sound condition free of rust or other damage which might compromise containment. Hoses, valves, fittings, caps, filler nozzles, and associated hardware shall be maintained in proper working condition at all times. The location of fuel tanks shall be shown on the Erosion and Sedimentation Plan ( "Site Map "). 7. Hazardous Waste Management and Spill Reporting Plan — Any hazardous or potentially hazardous waste that is brought onto the construction site will be handled properly in order to reduce the potential for storm water pollution. All materials used on this construction site will be properly stored, handled and dispensed following any applicable label directions. Material Safety Data Sheets (MSDS) information will be kept on site for any and all applicable materials. Should an accidental spill occur, immediate action will be undertaken by the General Contractor to contain and remove the spilled material. All hazardous materials will be disposed of by the Contractor in the manner specified by local, state, and federal regulations and by the manufacturer of such products. As soon as possible, the spill will be reported to the appropriate state and local agencies. As required under the provisions of the Clean Water Act, any spill or discharge entering the waters of the United States will be properly reported. The General Contractor will prepare a written record of any such spill and will provide notice to the Owner within 24 -hours of the occurrence of the spill. A spill report form is located in Appendix E. Any spills of hazardous materials in quantities in excess of Reportable Quantities as defined by EPA or the State Agency regulations, shall be immediately reported to the EPA National Response Center (1- 800-- 424 -8802) and the Minnesota Pollution Control Agency shall be notified at their 24 -hour telephone number: 651 - 649 -5451. Refer to Part V, Item C of the General Permit Authorization to Discharge Storm Water Associated With Construction Activity Under the National Pollutant Discharge Elimination System/State Disposal System Permit Program. Storage and disposal of hazardous waste must be in compliance with MPCA regulations. The Reference that provides information as to quantities of hazardous material reported is available at the following web site: http://www.pca.state,mn.us/waste/pubs/business.html#general or call the MPCA customer assistance center at (651) 297 -2274. . The reportable quantity for petroleum products is a five-gallon minimum in Minnesota. Spills of all other chemicals or materials, any quantity is reportable. If in doubt, report. In order to minimize the potential for a spill of hazardous materials to come in contact with storm water, the following steps will be implemented: a) All materials with hazardous properties (such as pesticides, petroleum products, fertilizers, detergents, construction chemicals, acids, paints, paint solvents, cleaning solvents, additives for soil stabilization, concrete, curing compounds and additives, etc.) will be stored in a secure location, under cover, when not in use. 02370 -16 WaI --Mart Expansion Store No. 1861 -04, Oak Park Heights, Minnesota Date: July 1, 2005 b C) e) The minimum practical quantity of all such materials will be kept on the job site and scheduled for delivery as close to time of use as practical. A spill control and containment kit (containing for example, absorbent such as kitty litter or sawdust, acid neutralizing agent, brooms, dust pans, mops, rags, gloves, goggles, plastic and metal trash containers, etc.) will be provided at the storage site. d) All of the product in a container will be used before the container is disposed of. All such containers will be triple rinsed, with water prior to disposal. The rinse water used in these containers will be disposed of in a manner in compliance with state and federal regulations and will not be allowed to mix with storm water discharges. All products will be stored in and used from the original container with the original product label. f) All products will be used in strict compliance with instructions on the product label. g) The disposal of excess or used products will be in strict compliance with instructions on the product label. 8. Long -Term Pollutant Controls Storm water pollutant control measures installed during construction, that will also provide storm water management benefits after construction, include the storm water ponds in the southwest corner of the site. The other control measures are only temporary. The other permanent control measures include landscaping, storm sewer piping, and pavement surfacing. The site and erosion control procedures have been designed in accordance with the requirements of the City of Oak Park Heights and the Brown's Creek Watershed District. The receiving waters for both pre and post construction storm water is the on -site storm sewer, which discharges to water quality ponds that discharge into the MNDOT ditch and then eventually into Menard's Pond. From there it goes north into Stillwater into a pond next to Target and eventually into Long Lake, approximately 1 mile west - northwest of the site. None of these are Special Waters. C. Construction Phase "Best Management Practices" During the construction phase, the General Contractor shall implement the following measures: 1. Materials resulting from the clearing and grubbing or excavation operations shall be stockpiled up slope from adequate sedimentation controls. Materials removed to an off-site location shall be protected with appropriate controls and properly permitted. 2. The General Contractor shall designate areas on the erosion and sediment control Site Maps for equipment cleaning, maintenance, and repair. The General Contractor and subcontractors shall utilize such designated areas. Cleaning, maintenance, and repair areas shall be protected by a temporary perimeter bean, shall not occur within 150 feet of any waterway, and in areas located as far as practical from storm inlets. 3. Use of detergents for large scale washing is prohibited (i.e., vehicles, buildings, pavement surfaces, etc .) 4. Chemicals, paints, solvents, fertilizers, and other toxic materials must be stored in weatherproof containers. Except during application., the contents must be kept in trucks or within storage facilities. Runoff containing such material must be collected, removed from the site, treated, and disposed at an approved solid waste or chemical disposal facility. D. Off-Site Facilities In The Control of the General Contractor Whenever dirt, rock, or other materials are imported to the construction site or exported for placement in areas off of the primary construction site, the General Contractor is responsible for determining that all 02370-17 Wal -Mart Expansion Store No. 1861 -04, Oak Park Heights, Minnesota Date: July 1, 2005 VI. LOCAL PLANS storm water permitting and pollution control requirements are met for each and every site which receives such materials or from which such materials are taken. Prior to the disturbance of any such site, the General Contractor will furnish the Owner with a copy of the storm water permit issued for each such site, as well as a copy of the off -site Owners certification statement agreeing to implement storm water pollution prevention measures. The General Contractor will also furnish a copy of the SWPPP for each such site, including a description of the erosion control measures, which will be applied. At a minimum, each off -site area that provides or receives materials or is disturbed by project activities must implement erosion control measures consisting of perimeter controls on all down slope and side slope boundaries and must also provide for both temporary stabilization measures and for permanent revegetation after all disturbance is ended. In addition to this SWPPP, construction activities associated with this project must comply with any guidelines set forth by local regulatory agencies. The General Contractor shall maintain documents evidencing such compliance the SWPPP. VILINSPECTIONS AND SYSTEM MAINTENANCE Between the time this SWPPP is implemented and final Notice of Termination has been submitted, all disturbed areas and pollutant controls must be inspected daily. The purpose of site inspections is to assess performance of pollutant controls. The inspections will be conducted by the General Contractor's Site Superintendent. Based on these inspections, the General Contractor will decide whether it is necessary to modify this SWPPP, add or relocate controls, or revise or implement additional Best Management Practices in order to prevent pollutants from leaving the site via storm water runoff. The General Contractor has the duty to cause pollutant control measures to be repaired, modified, maintained, supplemented, or take additional steps as necessary in order to achieve effective pollutant control. Examples of specific items to evaluate during site inspections are listed below. This list is not intended to be comprehensive. During each inspection, the inspector must evaluate overall pollutant control system performance as well as particular details of individual system components. Additional factors should be considered as appropriate to the circumstances. A. Locations where vehicles enter and exit the site must be inspected for evidence of off-site sediment tracking. A stabilized construction exit shall be constructed where vehicles enter and exit. Exits shall be maintained or supplemented as necessary to prevent the release of sediment from vehicles leaving the site. Any sediment deposited on the roadway shall be swept as necessary throughout the day or at the end of every day and disposed of in an appropriate manner. Sediment shall not be washed into storm sewer systems. B. Sediment barriers, traps and basins must be inspected and they must be cleaned out in accordance with the MPCA requirements. Silt fences must be cleaned when sediment reaches 1/3 of the height of the silt - fence. All material excavated from behind sediment barriers or in traps and basins shall be incorporated into on-site soils or spread out on an upland portion of the site and stabilized. Additional sediment barriers must be constructed as needed. C. Inspections shall evaluate disturbed areas and areas used for storing materials that are exposed to rainfall for evidence of, or the potential for, pollutants entering the drainage system or discharging from the site. If necessary, the materials must be covered or original covers must be repaired or supplemented. Also, protective berms must be constructed, if needed, in order to contain runoff from material storage areas. All state and local regulations pertaining to material storage areas will be adhered to. D. Grassed areas shall be inspected to confirm that a healthy stand of grass is maintained. The site has achieved final stabilization once all areas are covered with building foundation or pavement, or have a stand of grass with at least 70 percent density or greater in accordance with General Permit requirements. The vegetative density must be maintained to be considered stabilized. Areas must be watered, fertilized, and reseeded as needed to achieve this requirement. 02370 -18 Wal -Mart Expansion Store No. 1861-04, Oak Park Heights, Minnesota Date: July 1, 2005 E. Temporary and permanent infiltration and sediment ponds shall be inspected to confirm they are operating and functioning as designed. Temporary and permanent sedimentation ponds shall be drained and the sediment removed when a depth of sediment collected reaches one-half the storage volume. Drainage and removal must be completed within 72 hours of discovery, or as soon as field conditions allow access. F. All discharge points must be inspected to determine whether erosion and sediment control measures are effective in preventing discharge of sediment from the site or impacts to receiving waters. The Inspection Report Fon (Appendix D) must identify all deficiencies, any corrections, whether they are identified during the current inspection or have occurred since the previous inspection, and any additional comments. Based on inspection results, any modification necessary to increase effectiveness of this SWPPP to an acceptable level must be made within 48 hours of the inspection. The inspection reports must be complete and additional remarks should be included if needed to fully describe a situation. An important aspect of the inspection report is the description of additional measures that need to be taken to enhance plan effectiveness. The inspection report must identify whether the site was in compliance with the SWPPP at the time of inspection and specifically identify all incidents of noncompliance. A responsible corporate officer (Vice President or higher) must sign a letter delegating the site superintendent as the authorized position for conducting the required inspections. A draft form of this authorization is included in Appendix D. The inspector must be a certified "Storm Water Professional" through the Wal -Mart training program. Inspection reports must include an original, authorized signature and date of the inspection. Inspection reports must be retained by the General Contractor as an integral part of this SWPPP for at least five years from the date of submission of the Notice of Termination of permit coverage. Ultimately, it is the responsibility of the General Contractor to assure the adequacy of site pollutant discharge controls . Actual physical site conditions or contractor practices could make it necessary to install more structural . controls than are shown on the plans. (For example, localized concentrations of runoff could make it necessary to install additional sediment barriers.) Assessing the need for additional controls and implementing them or adjusting existing controls will be a continuing aspect of this SWPPP until the site achieves final stabilization. 02370 -19 Wal-Mart Expansion Store No. 1861 -04, Oak Park Heights, Minnesota Date: July 1, 2005 APPENDIX A - VICINITY MAP APPENDIX B - APPLICATION FOR GENERAL STORM WATER PERMIT FOR CONSTRUCTION ACTIVITY (MN R100001) & APPLICATION FOR PERMIT TRANSFER/MODIFICATION.

Permit A • s heat on rere • uist es For Questions 1 -3, please refer to the NPDES /SDS General Storm -water Permit for Construction Activity and the flowchart at the end of these instructions. 1. Indicate if a Storm -water Pollution Prevention Plan (SWPPP) has been prepared and the appropriate sections (a through h of this question) have been addressed by answering "Yes" or "No ". A SWPPP is a plan for storm -water discharge that includes erosion prevention measures and sediment controls that, when implemented, will decrease soil erosion on a parcel of land and decrease pollution in receiving waters. This plan must be developed prior to submitting a permit application. A sample plan and development tools are available on the U.S. Environmental Protection Agency web page at http:ilcfpub 1. epa. govinpdesistorrnwater!swppp.efn For section "h" indicate if an Environmental Review has been completed if required, by answering "Yes" or "No" or "NA". Environmental review looks at how a proposed project could potentially affect the environment and looks at ways to avoid or minimize impacts before the project is permitted and built. Examples of categories that may need an environmental review include residential development; industrial, commercial, and institutional facilities and also highway projects. For certain projects, environmental review is mandatory. For more details see the Guide to Minnesota Environmental Review Rules, Chapter 6. This can be found at http://www.mn.plan.state.mn.uslpdf/rulguid3,pdf 2. Indicate if discharges to special waters have been identified and addressed by answering "Yes" or "No" or "NA" (not applicable) on the Permit Application. The questions at the right can help in making this determination. Special waters have qualities that warrant extra protection. A list of these special water categories can be found in Appendix A of the permit. For information on special waters near the project's area, see the Minnesota Pollution Control Agency (MPCA) Web page at http :llwww.pca. state. mn.uslpublications i wq -strx 1--0 5 . xis Oat t of Life ency Special Waters 2.a. Do you have a special water that is within 2,000 feet of the project? (see Appendix A of the Permit for a list of these Special water categories) 2.b. Do you have storm-water discharges that are within 2,000 feet of these special waters? 2.c. Will the discharges identified in 2.b. flow to the special waters? September 2003 3. Indicate by answering "Yes" or "No" whether the project will include alternative methods for the permanent storm - water management system or will disturb 50 acres or more and have a discharge point (including sheet flow) that is within 2000 feet of and flows to an impaired or special water. Additional review from the MPCA is required in these cases. You have the option of proposing an alternative, innovative, permanent storm -water management system. You must send in the permit application and the additional required information (see Part III.C.5 of the Permit) at least 90 days prior to the start of construction if you choose this approach. You must receive an approval letter from the MPCA for this method before beginning construction. The application and SWPPP need to be submitted to the MPCA a minimum of 30 days prior to the start of construction if the p roject disturbs 50 acres or more and drains to an impaired water or a special water listed in Appendix A of the permit. For a list and maps of impaired waters in MN go to wwtiv .pca.state.mn.us /Wateritmdl.ht nl 4. The application requires a $400 application fee. Indicate that the application fee has been enclosed by answering "Yes". Please make checks payable to: Minnesota Pollution Control Agency and submit the check with the completed application to: MPCA, Regional Environmental Management Division, 520 Lafayette Road North, St. Paul, MN 55155 - 4194. Applications received without the required fee will be returned to the sender. Construction Activi ty Infor ath 5. List the construction project's name. If the project does not have a name, list the type of project and a brief description (for example, "I- -35E/1 -494 Interchange" or "Highway 169 bridge replacement ( #79605) at the Rum River "). 6. Provide an address (if available) and brief description of the construction activity's location (for example, "North West Corner of the Intersection of 45 Street and Irving Avenue, Minneapolis, MN "). List the County Parcel ID# for the project if it is known. If there are multiple numbers within the project, attach a list. Parcel Identification Numbers are unique numbers assigned by the County. Listing the County Parcel ID# is not required if not available (for example, highway projects) Provide the names of all cities, counties, and townships the construction activity takes place in (for example, a roadway may cross county, city, or township boundaries). 7. List, in acres, the amount of area to be disturbed for this project. 8. Attach the required map and indicate that it is included with the permit application. United States Geological Survey (USGS) 7.5- minute quad maps or equivalent maps may be used. USGS 7.5- minute quad maps may be ordered at http: / /store.usgs.gov/ 9. Indicate the type of construction activity by checking the appropriate box. Please describe the project if you check "Other ". 10. Indicate to the nearest quarter acre, the existing and resulting areas of impervious surfaces. Impervious surface means a constructed hard surface that either prevents or retards the entry of water into the soil and causes water to run off the surface in greater quantities and at an increased rate of flow than prior to development. Examples include rooftops, sidewalks, patios, driveways, parking lots, storage areas, and concrete, asphalt, or gravel roads. (a.) "Existing" area means the area of impervious surface that is present prior to the start of this construction project. (b.) "Post construction" means the entire area of impervious surface after construction is completed. Subtract (a.) from (b.) to determine the area of new impervious surface. 11. For p rojects creating one or more acres of cumulative new impervious surfaces, check the appropriate box to indicate which type(s) of permanent storm-water management practices that will be used. The "Other" box is limited to those situations (such as proximity to bedrock) that are described in Part III.0 of the permit. See the permit for a further description. If the "Other' box is checked, describe which situation outlined in Part III. C. fits the project and what other permanent treatment (such as grassed swales, smaller ponds and/or grit chambers) will be used on the project. 12.

The commencement of any construction activity (e.g., land disturbing activities) covered under Part I.A. of this permit is prohibited until permit coverage under this permit is effective or, if applicable, until the MPCA has issued an individual NPDES/SDS construction storm water permit for the project. a. Except as provided in subp. 3.b. and 3.c. below, permit coverage will become effective seven (7) days after the postmarked date of the completed application form. b. For p rojects disturbing 50 acres or more, that have a discharge point on the project that is within 2000 feet of and flows to, a special water listed in Appendix A, Part B. or waters listed as impaired under section 303(d) of the federal Clean Water Act, the applicants must submit a completed application and SWPPP to the MPCA at least thirty (30) days prior to the commencement of construction activities. MPCA staff will review the SWPPP submitted with the completed application and unless the Permittee is notified in writing that the SWPPP does not meet the general permit requirements, permit coverage will become effective 30 days after the postmarked date or MPCA date -stamp (whichever is first) of the completed application. c. For proposals to use Alternative Method(s) for the Permanent Storm Water Management System under Part III.C.5, the applicants must submit a completed application and SWPPP, includin g the Alternative Method documentation under Part III.C.5, to MPCA for review and approval at least 90 days prior to the proposed starting date of construction activity. i. The MPCA will notify the applicant within the 90 -day period, in writing, whether the alternative method is approved or not approved and, if applicable, the basis for denial. ii. The applicant may re- submit the alternative method after addressing the MPCA's basis for denial. The MPCA will respond within 30 days. iii. Permit coverage will become effective upon receipt of an alternative treatment method approval letter from MPCA. Any construction activity on the project is not covered under this permit until receiving the alternative treatment approval letter. 4. Coverage Letter. For projects under subpart 3.a. of this part, the Permittee(s) will receive a permit letter and certificate acknowledging permit coverage, usually within 30 days of the postmarked date of the completed application. wq- strm2 -51 Page 5 of 26 Permit No: MN R100001 C. TERMINATION OF COVERAGE wq- strm2 -51 Page 6 of 26 Permit No: MN R10000 l 5. Change of Coverage. For storm water discharges from construction projects where the owner or operator changes, (e.g., an original developer sells portions of the property to various homebuilders) the new owner or operator must submit a subdivision registration within 7 days of assuming operational control of the site, commencing work on their portion of the site, or of the legal transfer, sale or closing on the property. For instances where an owner or operator of an entire project changes after an application has been submitted under Part II, the new owner or operator must submit an application for permit transfer/modification within 7 days of assuming control of the site or commencing work on -site, or of the legal transfer, sale or closing on the property. Late submittals will not be rejected; however, the MPCA reserves the right to take enforcement for any unpermitted discharges or permit noncompliance for the new registered party that has assumed control of the site. For storm water discharges from construction activities where the owner or operator changes, the new owner or operator can implement the original SWPPP created for the project or develop and implement their own SWPPP. Permittee(s) shall ensure either directly or through coordination with other Permittee(s) that their SWPPP meets all terms and conditions of this permit and that their activities do not render another party's erosion prevention and sediment control Best Management Practices (BMPs)." 1. Permittee(s) wishing to terminate coverage under this permit must submit a Notice of Termination (NOT) to the MPCA. Compliance with this permit is required until a NOT is submitted. The Permittee(s) authorization to discharge under this permit terminates at midnight of the day the NOT is signed. 2. All Permittee(s) must submit a NOT within thirty (30) days after one or more of the following conditions have been met: a. Final stabilization (see Part IV.G. and definition in Appendix B ) has been achieved on all portions of the site for which the Permittee is responsible (including the removal of all temporary measures such as silt fence, and if applicable, returning agricultural land to its pre - construction agricultural use); b. Another owner /operator (Permittee) has assumed control according to Part II.B.5 over all areas of the site that have not been finally stabilized; or c. For residential construction only, temporary erosion protection and down gradient perimeter control for individual lots has been completed and the residence has been transferred to the homeowner. Additionally, the Permittee must distribute the MPCA's "homeowner factsheet" to the homeowner to inform the homeowner of the need for, and benefits of, final stabilization. 3. Permittee(s) that use an alternative method for the permanent storm water management system as described in Part III.C.5, are prohibited from terminating this permit until final stabilization has been achieved on site and either: a. The two years of monitoring data has been submitted to the MPCA and the MPCA has determined that the required treatment has been achieved. The Permittee will be notified in writing within 30 days after the monitoring data has been submitted. If the Permittee has not heard from the MPCA within 30 days after submitting the required data, the Permittee can submit a Notice of Termination. wq- strn2-51 Page 7 of 26 Permit No: MN 8100001 b. The Permittee can submit a Notice of Termination, even if the timeframe is less than two years, if the MPCA determines that the alternative method is achieving the required treatment. During the monitoring and evaluation of the alternative method, the Permittee is not responsible for other permit requirements that have been transferred as described in Part II.B.5. PART III. STORM WATER DISCHARGE DESIGN REQUIREMENTS A. STORM WATER POLLUTION PREVENTION PLAN The owner must develop a Storm Water Pollution Prevention Plan (SWPPP). The SWPPP shall be completed prior to submitting any permit application and prior to conducting any construction activity by any required Permittee(s). The plan must be a combination of narrative, plan sheets and if appropriate standard detail sheets that address the foreseeable conditions, at any stage in the construction or post construction activities. The plan must include a description of the nature of the construction activity. The plan must address the potential for discharge of sediment and/or other potential pollutants from the site. For storm water discharges from construction activities where the owner or operator changes, the new owner or operator can implement the original SWPPP created for the project or develop and implement their own. SWPPP. Permittee(s) shall ensure either directly or through coordination with other Permittee(s) that their SWPPP meets all terms and conditions of this permit and that their activities do not render another party's erosion prevention and sediment control Best Management Practices (BMPs) ineffective. 1. As part of the SWPPP the owner must identify a person knowledgeable and experienced in the application of erosion prevention and sediment control BMPs who will oversee the implementation of the SWPPP, and the installation, inspection and maintenance of the erosion prevention and sediment control BMPs before and during construction. The owner must identify who will have the responsibility for long term operation and maintenance of the permanent storm water management system (see Part HI.C.). The owner shall develop a chain of responsibility with all operators on the site to ensure that the SWPPP will be implemented and stay in effect until the construction project is complete, the entire site has undergone final stabilization, and a NOT has been submitted to the MPCA. 2. The SWPPP must incorporate the requirements of Part III (Storm Water Discharge Design Requirements), Part IV (Construction Activity Requirements) and Appendix A for the project. A narrative describing the timing for installation of all erosion prevention and sediment control BMPs required in Part III, Part IV and Appendix A must also be included in the plan. 3. The SWPPP requirements must be incorporated into the project's final plans and specifications and/or project documentation, as appropriate, and must include: a. Location and type of all temporary and permanent erosion prevention and sediment control BMPs along with procedures to be used to establish additional temporary BMPs as necessary for the site conditions during construction. Standard plates and/or specifications for the BMPs used on the project must be included in the final plans and specifications for the project. b. A site map with existing and final grades, including dividing lines and direction of flow for all pre and post - construction storm water runoff drainage areas located within the project limits. The site map must also include impervious surfaces and soil types. c. Locations of areas not to be disturbed. Page 8 of 26 Permit No: MN R 10000 I d. Location of areas where construction will be phased to minimize duration of exposed soil areas. e. All surface waters and existing wetlands, which can be identified on maps such as United States Geological Survey 7.5 minute quadrangle maps or equivalent maps within one-half mile from the project boundaries, which will receive storm water runoff from the construction site, during or after construction. 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. f. Methods to be used for final stabilization of all exposed soil areas. 4. The Permittee(s) must amend the SWPPP as necessary to include additional requirements, such as additional or modified BMPs, designed to correct problems identified or address situations whenever: a. There is a change in design, construction, operation, maintenance, weather or seasonal conditions that has a significant effect on the discharge of pollutants to surface waters or underground waters; b. Inspections or investigations by site operators, local, state or federal officials indicate the SWPPP is not effective in eliminating or significantly minimizing the discharge of pollutants to surface waters or underground waters or that the discharges are causing water quality standard exceedances; or c. The SWPPP is not achieving the general objectives of controlling pollutants in storm water discharges associated with construction activity, or the SWPPP is not consistent with the terms and conditions of this permit. d. At any time after permit coverage is effective, the MPCA may determine that the project's storm water discharges may cause, have reasonable potential to cause, or contribute to non - attainment of any applicable water quality standard, or that the SWPPP does not incorporate the requirements in Part III.A.7 related to an approved Total Maximum Daily Load (TMDL) implementation plan that contains construction storm water related requirements. If MPCA makes such determination(s) or any of the determinations in Parts III.A.4.a. -4.c., MPCA will notify the Permittees in writing. In response, the Permittees must develop a supplemental BMP action plan or appropriate SWPPP amendments describing SWPPP modifications to address the identified concerns and submit information requested by MPCA, which may include an individual permit application. If MPCA's written notification requires a response, failure to respond within the specified timeframe constitutes a permit violation. 5. The SWPPP must factor in any findings of and include any storm water mitigation measures required as the result of any environmental, archeological or other required local, state or federal review conducted for the project. For the purposes of this permit provision, mitigation measures mean avoiding, minimizing, rectifying (e.g., repairing, rehabilitating, restoring), reducing, eliminating or compensating for impacts related to: (I) storm water discharges associated with the project's construction activity; and ( erosion prevention, sediment control and the permanent storm water management system for the project. 6. The SWPPP must provide additional measures as necessary to assure compliance with surface and ground water standards in Minn. R. chapters 7050 and 7060 in karst areas and to ensure protection of drinking water supply management areas (see Minn. R. 4725.4450). 7. If runoff from the site discharges to an impaired water which has an approved TMDL implementation plan containing requirements for construction storm water discharges, the Permittee must include the following in the SWPPP: a. identify the receiving water and the areas of the site discharging to it; and b. BMPs that are appropriate for the site and sufficient to comply with all applicable requirements of the TMDL implementation plan. B. TEMPORARY SEDIMENT BASINS Page 9 of 26 Permit No: MN R 1 00001 Where ten (10) or more acres of disturbed soil drain to a common location, a temporary (or permanent) sediment basin must be provided prior to the runoff leaving the construction site or entering surface waters. The Permittee is encouraged, but not required, to install temporary sediment basins where appropriate in areas with steep slopes or highly erodible soils even if less than ten (10) acres drains to one area. The basins must be designed and constructed according to the following requirements: 1. The basins must provide storage below the outlet pipe for a calculated volume of runoff from a 2 year, 24 hour storm from each acre drained to the basin, except that in no case shall the basin provide less than 1 800 cubic feet of storage below the outlet pipe from each acre drained to the basin. 2. Where no such calculation has been performed, a temporary (or permanent) sediment basin providing 3,600 cubic feet of storage below the outlet pipe per acre drained to the basin, shall be provided where attainable until final stabilization of the site. 3. Temporary basin outlets must be designed to prevent short-circuiting and the discharge of floating debris. The basin must be designed with the ability to allow complete basin drawdown (e.g., perforated riser pipe wrapped with filter fabric and covered with crushed gravel, pumps or other means, see Part IV.D.) for maintenance activities, and provide a stabilized emergency overflow to prevent failure of pond integrity. Energy dissipation must be provided for the basin outlet (see Part IV.B.4). 4. The temporary (or permanent) basins must be constructed and made operational concurrent with the start of soil disturbance that is upgradient of the area and contributes runoff to the pond. 5. Where the temporary sediment basin is not attainable due to site limitations, equivalent sediment controls such as smaller sediment basins, and/or sediment traps, silt fences, vegetative buffer strips, or any appropriate combination of measures are required for all down slope boundaries of the construction area and for those side slope boundaries deemed appropriate as dictated by individual site conditions. In determining whether installing a sediment basin is attainable, the Permittee must consider public safety and may consider factors such as site soils, slope, and available area on site. This determination must be documented in the SWPPP. wq- strm2 -5 1 C. PERMANENT STORM WATER MANAGEMENT SYSTEM All storm water must be discharged in a manner that does not cause nuisance conditions, erosion in receiving channels or on downs lope properties, or inundation in wetlands causing a significant adverse impact to the wetlands. Where a project's ultimate development replaces vegetation and/or other pervious surfaces with one or more acres of cumulative impervious surface, a water quality volume of 1 /2 inch of runoff from the new impervious surfaces created by the project must be treated by one of the methods outlined in Part III.C.1 through Part III.C.5 prior to the runoff leaving the construction site or entering surface waters (excluding drainage systems that convey storm water to a constructed permanent storm water management facility designed to treat the water quality volume from the project). For those areas of a project where there is no feasible way to meet the treatment requirement for the water quality volume, other treatment such as grassed swales, smaller ponds or grit chambers is required prior to discharge to surface waters. A cumulative maximum of (3) three acres or 1% of project size whichever is larger can be treated in this manner. Where the proximity to bedrock precludes the installation of any of the permanent storm water management practices outlined in Part III.C., other treatment, such as grassed swales, smaller ponds, or grit chambers, is required prior to discharge to surface waters. For work on road projects where the lack of right of way precludes the installation of any of the permanent storm water management practices outlined in Part III.C., other treatment such as grassed swales, smaller ponds, or grit chambers, is required prior to discharge to surface waters. 1. Wet Sedimentation Basin e. The basin must provide a stabilized emergency overflow to accommodate storm events in excess of the basin's hydraulic design. Page 10 of 26 Permit No: MN R100001 a. The basin must have a permanent volume of 1800 cubic feet of storage below the outlet pipe for each acre that drains to the basin. The basin's permanent volume must reach a minimum depth of at least 3 feet and must have no depth greater than 10 feet. The basin must be configured such that scour or resuspension of solids is minimized. b. The basin's water quality volume is calculated as V2 inch of runoff from the new impervious surfaces created by the project. c. Basin outlets shall be designed such that the water quality volume is discharged at no more than 5.66 cubic feet per second (cfs) per acre of surface area of the pond. d. Basin outlets must be designed to prevent short - circuiting and the discharge of floating debris. Basin outlets must have energy dissipation. f. Adequate maintenance access must be provided (typically 8 ft. wide) for future maintenance of the basin. 2. Infiltration/Filtration wq- strm2 -51 Page 11 of 26 Permit No: MN R100001 Infiltration/Filtration options include but are not limited to: infiltration basins, infiltration trenches, rainwater gardens, sand filters, organic filters, bioretention areas, enhanced swales, dry storage ponds with underdrain discharge, off -line retention areas and natural depressions. Infiltration must be used only as appropriate to the site and land uses. Settleable solids, floating materials, oils and grease should be removed from the runoff to the maximum extent practicable before runoff enters the infiltration/filtration system. Filtration systems must have a reasonable chance of achieving approximately 80% removal of total suspended solids. The Permittee(s) must evaluate the impact of constructing an infiltration practice on existing hydrologic features (e.g., existing wetlands) and try to maintain pre - existing conditions (e.g., do not breach a perched water table which is supporting a wetland). For a discussion of ground water warnings, design measures, maintenance considerations or other retention, detention, and treatment devices, see the MPCA's Protecting Water Quality in Urban Areas found on the MPCA's web - site. a. Infiltration systems should not be excavated to final grade until the contributing drainage area has been constructed and fully stabilized. b. During construction of an infiltration system, rigorous sediment and erosion controls (e.g., diversion berms) should be used to keep sediment and runoff completely away from the infiltration area. The area must be staked off and marked so that heavy construction equipment will not compact the soil in the proposed infiltration area. c. To prevent clogging of the infiltration or filtration system, a pretreatment device such as a vegetated filter strip, small sedimentation basin, or water quality inlet (e.g., grit chamber) must be used to settle particulates before the storm water discharges into the infiltration or filtration system. d. Infiltration or filtration systems shall be sufficient to infiltrate or filter a water quality volume of 1 /2 inch of runoff from the new impervious surfaces created by the project. e. The water quality volume shall discharge through the soil or filter media in 48 hours or less. Additional flows that cannot be infiltrated or filtered in 48 hours should be routed to bypass the system through a stabilized discharge point. A way to visually verify that the system is operating as designed rust be provided. f. Appropriate on -site testing shall be conducted to ensure a minimum of 3 feet of separation from the seasonally saturated soils (or from bedrock) and the bottom of the proposed infiltration system. Calculations and computer model results that demonstrate the design adequacy of the infiltration system must be included as part of the SWPPP. g- Adequate maintenance access must be provided (typically 8 ft. wide) along with a maintenance plan identifying whom will be performing future maintenance of the infiltration or filtration system. h. Use of designed infiltration systems from industrial areas with exposed significant materials or from vehicle fueling and maintenance areas is prohibited. 3. Regional Ponds Regional ponds can be used provided that they are constructed ponds, not a natural wetland or waterbody, (wetlands used as regional ponds must be mitigated for, see Appendix A) and designed in accordance with this permit's design requirements (see Part III.C.1) for all water from 4. Combination of Practices 5. Alternative Method wq- sttm2 -51 Page 12 of 26 Permit No: MN R100001 impervious surfaces that reach the pond. Permittees shall not construct regional ponds in wetlands, regardless of their condition, quality or designation by local plans, unless the mitigative sequence in Appendix A. D.2 of this permit has been completed. There must be no significant degradation of the waterways between the project and the regional pond. The owner must obtain written authorization from the applicable local governmental unit (LGU) or private entity that owns and maintains the regional pond. The LGU's or private entity's written authorization must identify that the regional pond will discharge the water quality volume ('/2 inch of runoff from the impervious watershed area) at no more than 5.66 cfs per acre of surface area of the pond. The owner must include the LGU's or private entity's written authorization in the SWPPP. The LGU's or private entity's written authorization must be obtained before the owner finalizes the SWPPP and before any application for this permit is made to the MPCA. A combination of practices, including those required by a LGU, which meet the requirements of Part III.C.1, 2 and 3 respectively, (i.e., wet sedimentation basins, infiltration/filtration, and regional ponds) may be used such that the water quality volume of '/A inch of runoff from the new impervious surfaces created by the project is accounted for in the owner's permanent storm water management system (e.g., '4 inch infiltrated and % inch treated through a wet sedimentation basin). If any combination of these practices is used, the SWPPP must contain documentation (e.g., LGU or private entity's authorization, infiltration computer model results or calculations, etc.) identifying the volume that each practice addresses. Where an alternative, innovative treatment system is proposed and demonstrated by calculation, design or other independent methods to achieve approximately 80% removal of total suspended solids on an annual average basis, the Commissioner will approve the method if the process outlined in Part II.B.3.c. is completed, and the following information is submitted: a. All calculations, drainage areas, plans, and specifications for the proposed alternative method and a graphic representation of the area to be served by the method. These items must be included in the SWPPP and submitted to the MPCA at least 90 days prior to the proposed starting date of the construction activity. b. A 2 year monitoring plan to sample runoff from the proposed method. The plan must include a discussion of the methods used to collect samples, location where samples will be taken (upstream and downstream of the proposed method), frequency of samples (minimum of six runoff events sampled), identify lab used to analyze the samples and quality assurance and quality control methods to be used. The plan must include a schedule for submitting the monitoring data annually. c. A mitigation plan that addresses how the water quality volume will be treated in the event that the monitoring data shows the proposed alternative treatment method does not function as designed. d. The alternative method must achieve approximately 80% removal of total suspended solids on an average annual basis for the conditions expected at the site. The design must also consider public safety, health and water quality concerns. Proprietary information on effectiveness will not be considered for alternative treatment method review and approval. The SWPPP,aII changes to it, and inspections and maintenance records must be kept at the site during construction by the Permittee who has operational control of that portion of the site. The SWPPP can be kept in either the field office or in an on site vehicle. No construction activity on the project is covered under this permit until the applicant receives an alternative treatment approval letter from the MPCA as described in Part II.B.3.c. D. RECORD RETENTION All owner(s) must keep the SWPPP, along with the following additional records, on file for three years after submittal of the NOT as outlined in Part II.C. This does not include any records after submittal of the NOT. 1. Any other permits required for the project; 2. Records of all inspection and maintenance conducted during construction (see Part IV.E. Inspections and Maintenance); 3. All permanent operation and maintenance agreements that have been implemented, including all right of way, contracts, covenants and other binding requirements regarding perpetual maintenance; and 4. All required calculations for design of the temporary and permanent storm water management systems. PART IV. CONSTRUCTION ACTIVITY REQUIREMENTS A. STORM WATER POLLUTION PREVENTION PLAN The Permittee(s) must implement the SWPPP and the requirements of this part. The Best Management Practices (BMPs) identified in the SWPPP and in this permit must be installed in an appropriate and functional manner. B. EROSION PREVENTION PRACTICES Page 13 of 26 Permit No: MN R100001 1. The Permittee(s) must plan for and implement appropriate construction phasing, vegetative buffer strips, horizontal slope grading, and other construction practices that minimize erosion, so that the inspection and maintenance requirements of Part IV.E. are complied with. The location of areas not to be disturbed must be delineated (e.g. with flags, stakes, signs, silt fence etc.) on the development site before work begins. 2. All exposed soil areas with a continuous positive slope within 200 lineal feet of a surface water, must have temporary erosion protection or permanent cover for the exposed soil areas year round, according to the following table of slopes and time frames: Type of Slope Time (Maximum time an area can remain open when the area Steeper than 3:1 7 days is not actively being worked.) 10:1 to 3:1 14 days Flatter than 10:1 21 days Page 14 of 26 Permit No: MN R 1 0000 I These areas include constructed storm water management pond side scopes, and any exposed soil areas with a positive slope to a storm water conveyance system, such as a curb and gutter system, storm sewer inlet, temporary or permanent drainage ditch or other natural or man made systems that discharge to a surface water. Temporary stockpiles without significant silt, clay or organic components (e.g., clean aggregate stockpiles, demolition concrete stockpiles, sand stockpiles) are exempt from this requirement but must comply with PartIV.C.5. 3. The normal wetted perimeter of any temporary or permanent drainage ditch that drains water from a construction site, or diverts water around a site, must be stabilized within 200 lineal feet from the property edge, or from the point of discharge to any surface water. Stabilization must be completed within 24 hours of connecting to a surface water. 4. Pipe outlets must be provided with temporary or permanent energy dissipation within 24 hours of connection to a surface water. C. SEDIMENT CONTROL PRACTICES I. Sediment control practices must minimize sediment from entering surface waters, including curb and gutter systems and storm sewer inlets. 2. Sediment control practices must be established on all down gradient perimeters before any upgradient land disturbing activities begin. These practices shall remain in place until final stabilization has been established in accordance with Part IV.G. 3. The timing of the installation of sediment control practices may be adjusted to accommodate short -term activities such as clearing or grubbing, or passage of vehicles. Any short -term activity must be completed as quickly as possible and the sediment control practices must be installed immediately after the activity is completed. However, sediment control practices must be installed before the next precipitation event even if the activity is not complete. 4. All storm drain inlets must be protected by appropriate BMPs during construction until all sources with potential for discharging to the inlet have been stabilized. 5. Temporary soil stockpiles must have silt fence or other effective sediment controls, and cannot be placed in surface waters, including storm water conveyances such as curb and gutter systems, or conduits and ditches. 6. Vehicle tracking of sediment from the construction site must be minimized by BMPs such as stone pads, concrete or steel wash racks, or equivalent systems. Street sweeping must be used if wq- strm2 -51 a. Temporary or permanent drainage ditches and sediment basins that are designed as part of a treatment system (e.g., ditches with rock check dams) require sediment control practices only as appropriate for site conditions. b. If the down gradient treatment system is overloaded, additional upgradient sediment control practices must be installed to eliminate the overloading, and the SWPPP must be amended to identify these additional practices as required in Part III.A.4, a. through c. c. In order to maintain sheet flow and minimize rills and/or gullies, there shall be no unbroken slope length of greater than 75 feet for slopes with a grade of 3:1 or steeper. such BMPs are not adequate to prevent sediment from being tracked onto the street (see Part IV.E.4.d.). 7. The Permittee must install temporary sedimentation basins as required in Part III.B. of this permit. D. DEWATERING AND BASIN DRAINING 1. Dewatering or basin draining (e.g., pumped discharges, trench/ditch cuts for drainage) related to the construction activity that may have turbid or sediment laden discharge water must be discharged to a temporary or permanent sedimentation basin on the project site whenever possible. If the water cannot be discharged to a sedimentation basin prior to entering the surface water, it must be treated with the appropriate BMPs, such that the discharge does not adversely affect the receiving water or downstream landowners. The Permittee(s) must ensure that discharge points are adequately protected from erosion and scour. The discharge must be dispersed over natural rock riprap, sand bags, plastic sheeting or other accepted energy dissipation measures. Adequate sedimentation control measures are required for discharge water that contains suspended solids. 2. All water from dewatering or basin draining activities must be discharged in a manner that does not cause nuisance conditions, erosion in receiving channels or on downslope properties, or inundation in wetlands causing significant adverse impact to the wetland. E. INSPECTIONS AND MAINTENANCE Page 15 of 26 Permit No: MN R100001 1. The Permittee(s) (either the owner or operator, whoever is identified in the SWPPP) must routinely inspect the construction site once every seven (7) days during active construction and within 24 hours after a rainfall event greater than 0.5 inches in 24 hours. 2. All inspections and maintenance conducted during construction must be recorded in writing and these records must be retained with the SWPPP in accordance with Part III.D. Records of each inspection and maintenance activity shall include: a. Date and time of inspections; b. Name of person(s) conducting inspections; c. Findings of inspections, including recommendations for corrective actions; d. Corrective actions taken (including dates, times, and party completing maintenance activities); e. Date and amount of all rainfall events greater than 112 inch (0.5 inches) in 24 hours; and f. Documentation of changes made to the SWPPP as required in Part III.A.4. 3. Where parts of the construction site have undergone final stabilization, but work remains on other parts of the site, inspections of the stabilized areas may be reduced to once per month. Where work has been suspended due to frozen ground conditions, the required inspections and maintenance must take place as soon as runoff occurs at the site or prior to resuming construction, whichever comes first. wq- strm2 -51 Page 16 of 26 Permit No: MN R1 00001 4. All erosion prevention and sediment control BMPs must be inspected to ensure integrity and effectiveness. All nonfunctional BMPs must be repaired, replaced, or supplemented with functional BMPs. The Permittee(s) must investigate and comply with the following inspection and maintenance requirements: wq- strrn2 -5 a. All silt fences must be repaired, replaced, or supplemented when they become nonfunctional or the sediment reaches 1/3 of the height of the fence. These repairs must be made within 24 hours of discovery, or as soon as field conditions allow access. b. Temporary and permanent sedimentation basins must be drained and the sediment removed when the depth of sediment collected in the basin reaches 1/2 the storage volume. Drainage and removal must be completed within 72 hours of discovery, or as soon as field conditions allow access (see Part IV.D.). c. Surface waters, including drainage ditches and conveyance systems, must be inspected for evidence of sediment being deposited by erosion. The Permittee(s) must remove all deltas and sediment deposited in surface waters, including drainage ways, catch basins, and other drainage systems, and restabilize the areas where sediment removal results in exposed soil. The removal and stabilization must take place within seven (7) days of discovery unless precluded by legal, regulatory, or physical access constraints. The Permittee shall use all reasonable efforts to obtain access. If precluded, removal and stabilization must take place within seven (7) calendar days of obtaining access. The Permittee is responsible for contacting all local, regional, state and federal authorities and receiving any applicable permits, prior to conducting any work. d. Construction site vehicle exit locations must be inspected for evidence of off-site sediment tracking onto paved surfaces. Tracked sediment must be removed from all off-site paved surfaces, within 24 hours of discovery, or if applicable, within a shorter time to comply with Part IV.C.6. e. The Permittee(s) are responsible for the operation and maintenance of temporary and permanent water quality management BMPs, as well as all erosion prevention and sediment control BMPs, for the duration of the construction work at the site. The Permittee(s) are responsible until another Permittee has assumed control according to Part 11.8.5 over all areas of the site that have not been finally stabilized or the site has undergone final stabilization, and a NOT has been submitted to the MPCA. f. If sediment escapes the construction site, off -site accumulations of sediment must be removed in a manner and at a frequency sufficient to minimize off-site impacts (e.g., fugitive sediment in streets could be washed into storm sewers by the next rain and/or pose a safety hazard to users of public streets). 5. All infiltration areas must be inspected to ensure that no sediment from ongoing construction activities is reaching the infiltration area and these areas are protected from compaction due to construction equipment driving across the infiltration area. F. POLLUTION PREVENTION MANAGEMENT MEASURES The Permittee(s) shall implement the following pollution prevention management measures on the site: 1. Solid Waste: Collected sediment, asphalt and concrete millings, floating debris, paper, plastic, fabric, construction and demolition debris and other wastes must be disposed of properly and must comply with MPCA disposal requirements. Page 17 of 26 Permit No: MN R100001 2. Hazardous Materials: Oil, gasoline, paint and any hazardous substances must be properly stored, including secondary containment, to prevent spills, leaks or other discharge. Restricted access to storage areas must be provided to prevent vandalism. Storage and disposal of hazardous waste must be in compliance with MPCA regulations. 3. External washing of trucks and other construction vehicles must be limited to a defined area of the site. Runoff must be contained and waste properly disposed of. No engine degreasing is allowed on site. G. FINAL STABILIZATION The Permittee(s) must ensure final stabilization of the site. The Permittee(s) must submit a NOT within 30 days after final stabilization is complete, or another owner /operator (Permittee) has assumed control according to Part II.B.5 over all areas of the site that have not undergone final stabilization. Final stabilization can be achieved in one of the following ways: 1. All soil disturbing activities at the site have been completed and all soils must be stabilized by a uniform perennial vegetative cover with a density of 70 percent over the entire pervious surface area, or other equivalent means necessary to prevent soil failure under erosive conditions and; wq -stm 2 -51 a. All drainage ditches, constructed to drain water from the site after construction is complete, must be stabilized to preclude erosion; b. All temporary synthetic, and structural erosion prevention and sediment control BMPs (such as silt fence) must be removed as part of the site final stabilization; and c. The Permittee(s) must clean out all sediment from conveyances and from temporary sedimentation basins that are to be used as permanent water quality management basins. Sediment must be stabilized to prevent it from being washed back into the basin, conveyances or drainageways discharging off-site or to surface waters. The cleanout of permanent basins must be sufficient to return the basin to design capacity. 2. For residential construction only, final stabilization has been achieved when temporary erosion protection and down gradient perimeter control for individual lots has been completed and the residence has been transferred to the homeowner. Additionally, the Permittee must distribute the MPCA "homeowner factsheet" to the homeowner to inform the homeowner of the need for, and benefits of, final stabilization. PART V GENERAL PROVISIONS A.

Post construction. The water quality volume that must be treated by the project's permanent storm water management system described in Part III.C. shall be one (1) inch of runoff from the new impervious surfaces created by the project. 3. Buffer zone. An undisturbed buffer zone of not less than 100 linear feet from the special water (not including tributaries) shall be maintained at all times. Exceptions from this requirement for areas, such as water crossings or limited water access, are allowed if the Permittee fully documents in the SWPPP the circumstances and reasons that the buffer encroachment is necessary. All potential water quality, scenic and other environmental impacts of these exceptions must be minimized and documented in the SWPPP for the project. wq- strm2 -51 4. Enhanced runoff controls. The permanent storm water management system must be designed such that the pre and post project runoff rate and volume from the 1, and 2 -year 24 -hour precipitation events remains the same. 5. Temperature Controls. The permanent storm water management system must be designed such that the discharge from the project will minimize any increase in the temperature of trout stream receiving waters resulting from the 1, and 2-year 24 -hour precipitation events. This includes all tributaries of designated trout streams within the section that the trout stream is located. Projects that discharge to trout streams must minimize the impact using one or more of the following measures, in order of preference: D. REQUIREMENTS FOR DISCHARGING TO WETLANDS If the project has any storm water discharges with the potential for significant adverse impacts to a wetland (e.g., conversion of a natural wetland to a storm water pond) , the Permittee(s) must demonstrate that the wetland mitigative sequence has been followed in accordance with D.1 or D.2 of this appendix. 1. If the potential adverse impacts to a wetland on a specific project site have been addressed by permits or other approvals from an official statewide program (U.S. Army Corps of Engineers 404 program, Minnesota Department of Natural Resources, or the State of Minnesota Wetland Conservation Act) that are issued specifically for the project and project site, the Permittee may use the permit or other determination issued by these agencies to show that the potential adverse impacts have been addressed. For the purposes of this permit, deminimus actions are determinations by the permitting agency that address the project impacts, whereas a non - jurisdictional determination does not address project impacts. 2. If there are impacts from the project that are not addressed in one of the permits or other determinations discussed in Appendix A, Part D.1 (e.g., permanent inundation or flooding of the wetland, significant degradation of water quality, excavation, filling, draining), the Permittee must minimize all adverse impacts to wetlands by utilizing appropriate measures. Measures used must be based on the nature of the wetland, its vegetative community types and the established hydrology. These measures include in order of preference: wq- strm2 -51 b. Minimize any unavoidable impacts from the project and post project discharge. Page 21 of 26 Permit No: MN R100001 a. Minimize new impervious surfaces. b. Minimize the discharge from connected impervious surfaces by discharging to vegetated areas, or grass swales, and through the use of other non - structural controls. c. Infiltration or evapotranspiration of runoff in excess of pre - project conditions (up to the 2- year 24 -hour precipitation event). d. If ponding is used, the design must include an appropriate combination of measures such as shading, filtered bottom withdrawal, vegetated swale discharges or constructed wetland treatment cells that will limit temperature increases. The pond should be designed to draw down in 24 hours or less. e. Other methods that will minimize any increase in the temperature of the trout stream. a. Avoid all significant adverse impacts to wetlands from the project and post project discharge. c. Provide compensatory mitigation when the Permittee determines that there is no reasonable and practicable alternative to having a significant adverse impact on a wetland. For E. DISCHARGES REQUIRING ENVIRONMENTAL REVIEW Page 22 of 26 Permit No: MN R100001 compensatory mitigation, wetland restoration or creation shall be of the same type, size and whenever reasonable and practicable in the same watershed as the impacted wetland. This permit does not replace or satisfy any environmental review requirements, including those under the Minnesota Environmental Policy Act (MEPA) or the National Environmental Policy Act (NEPA). The owner must complete any environmental review required by law, including any required Environmental Assessment Work Sheets or Environmental Impact Statements, Federal environmental review, or other required review. F. DISCHARGES AFFECTING ENDANGERED OR THREATENED SPECIES This permit does not replace or satisfy any review requirements for Endangered or Threatened species, from new or expanded discharges that adversely impact or contribute to adverse impacts on a listed endangered or threatened species or adversely modify a designated critical habitat. The owner must conduct any required review and coordinate with appropriate agencies for any project with the potential of affecting threatened or endangered species, or their critical habitat. G. DISCHARGES AFFECTING HISTORIC PLACES OR ARCHEOLOGICAL SITES This permit does not replace or satisfy any review requirements for Historic Places or Archeological Sites, from new or expanded discharges which adversely affect properties listed or eligible for listing in the National Register of Historic Places or affecting known or discovered Archeological Sites. The owner must be in compliance with National Historic Preservation Act and conduct all required review and coordination related to historic preservation, including significant anthropological sites and any burial sites, with the Minnesota Historic Preservation Officer.

Individual BMPs found in this permit are described in the current version of Protecting Water Quality in Urban Areas, Minnesota Pollution Control Agency 2000. BMPs must be adapted to the site and can be adopted from other sources. However, they must be similar in purpose and at least as effective and stringent as MPCA's BMPs. (Other sources include manufacturers specifications, Storm Water Management for Construction Activities: Developing Pollution Prevention Plans and Best Management Practices, U.S. Environmental Protection Agency 1992, and Erosion Control Design Manual, Minnesota Department of Transportation, et al, 1993). 2. "Commissioner" means the Commissioner of the Minnesota Pollution Control Agency or the Commissioner's designee. 3. `Common Plan of Development or Sale" means a contiguous area where multiple separate and distinct land disturbing activities may be taking place at different times, on different schedules, but wq- strm2-5 Page 23 of 26 Permit No: MN R100001 under one proposed plan. One plan is broadly defined to include design, permit application, advertisement or physical demarcation indicating that land - disturbing activities may occur. 4. "Construction Activity" For this permit, construction activity includes construction activity as defined in 40 C.F.R. part 122.26(b)(14)(x) and small construction activity as defined in 40 C.F.R. part 122.26(b)(15). This includes a disturbance to the land that results in a change in the topography, existing soil cover (both vegetative and non - vegetative), or the existing soil topography that may result in accelerated storm water runoff, leading to soil erosion and movement of sediment into surface waters or drainage systems. Examples of construction activity may include clearing, grading, filling and excavating. Construction activity includes the disturbance of less than one acre of total land area that is a part of a larger common plan of development or sale if the larger common plan will ultimately disturb one (1) acre or more. 5. "Dewatering" means the removal of water for construction activity. It can be a discharge of appropriated surface or groundwater to dry and/or solidify a construction site. It may require Minnesota Department of Natural Resources permits to be appropriated and if contaminated may require other MPCA permits to be discharged. 6. "Energy Dissipation" means methods employed at pipe outlets to prevent erosion. Examples include, but are not limited to: concrete aprons, riprap, splash pads, and gabions that are designed to prevent erosion. 7.

All soil disturbing activities at the site have been completed and a uniform (e.g., evenly distributed, without large bare areas) perennial vegetative cover with a density of 70% of the native background vegetative cover for the area has been established on all unpaved areas and areas not covered by permanent structures, or equivalent permanent stabilization measures (such as the use of riprap, gabions, or geotextiles) have been employed; b. For individual lots in residential construction by either: (a) The homebuilder completing final stabilization as specified above, or (b) the homebuilder establishing temporary stabilization including perimeter controls for an individual lot prior to occupation of the home by the homeowner and informing the homeowner of the need for, and benefits of, final stabilization. (Homeowners typically have an incentive to put in the landscaping functionally equivalent to final stabilization as quick as possible to keep mud out of their homes and off sidewalks and driveways.); or c. For construction projects on land used for agricultural purposes (e.g., pipelines across crop or range land) final stabilization may be accomplished by returning the disturbed land to its preconstruction agricultural use. Areas disturbed that were not previously used for agricultural activities, such as buffer strips immediately adjacent to surface waters and drainage systems, and areas which are not being returned to their preconstruction agricultural use must meet the final stabilization criteria in (a) or (b) above. 9. "General Contractor" means the party who signs the construction contract with the owner to construct the project described in the final plans and specifications. Where the construction project involves more than one contractor, the general contractor will be the party responsible for managing wq-strm2-51 Page 24 of 26 Peanut No: MN R100001 the project on behalf of the owner. In some cases, the owner may be the general contractor. In these cases, the owner may contract an individual as the operator who would become the Co- Permittee. 10.

"National Pollutant Discharge Elimination System (NPDES)" means the program for issuing, modifying, revoking, reissuing, terminating, monitoring, and enforcing permits under the Clean Water Act (Sections 301, 318, 402, and 405) and United States Code of Federal Regulations Title 33, Sections 1317, 1328, 1342, and 1345.. 13. "Normal Wetted Perimeter" means the area of a conveyance, such as a ditch, channel, or pipe that is in contact with water during flow events that are expected to occur once every year. 14. "Notice of 'Termination" means notice to terminate coverage under this permit after construction is complete, the site has undergone final stabilization, and maintenance agreements for all permanent facilities have been established, in accordance with all applicable conditions of this permit. Notice of Termination forms are available from the MPCA. 15. "Operator" means the person (usually the general contractor), designated by the owner, who has day to day operational control and/or the ability to modify project plans and specifications related to the SWPPP. The person must be knowledgeable in those areas of the permit for which the operator is responsible, (Part II.B. and Part IV.) and must perform those responsibilities in a workmanlike manner. 16. "Owner" means the person or party possessing the title of the land on which the construction activities will occur; or if the construction activity is for a lease holder, the party or individual identified as the lease holder; or the contracting government agency responsible for the construction activity. 17.

Page 25 of 26 Permit No: MN R100001 21 "Small Construction Activity" means small construction activity as defined in 40 C.F.R. part 122.26(b)(15) . Small construction activities include clearing, grading and excavating that result in land disturbance of equal to or greater than one acre and less than five acres. Small construction activity includes the disturbance of less than one (1) acre of total land area that is part of a larger common plan of development or sale if the larger common plan will ultimately disturb equal to or greater than one and less than five (5) acres. 22. "Stabilized" means the exposed ground surface has been covered by appropriate materials such as mulch, staked sod, riprap, wood fiber blanket, or other material that prevents erosion from occurring. Grass seeding is not stabilization. 23.

Proof roll prepared base material surface to check for unstable areas in accordance with Section 02300 including documentation and re -proof rolling as required. Paving work shall begin only after unsuitable areas have been corrected and are ready to receive paving. B. Remove loose material from compacted base material surface immediately before placing the bituminous base course. C, Establish and maintain required lines and elevations. D. Cover the surfaces of curbs, gutters, manholes and other structures on which the asphaltic concrete mixture will be placed, with a thin, uniform coat of liquid asphalt. Where the asphaltic concrete mixture will be placed against the vertical face of an existing pavement, clean the vertical face to remove foreign substances and apply a coating of liquid asphalt at a rate of approximately 0.25 gallons per square yard. 3.2 APPLICATION A. A bituminous prime coat will not be required on this project unless indicated on the plans. 13. Tack Coat: 1. Apply to contact surfaces of previously constructed asphaltic concrete base courses or Portland cement concrete and surfaces abutting or projecting into asphaltic concrete or into asphaltic concrete pavement. 2. Apply tack coat to asphaltic concrete base course or sand asphalt base course. Apply emulsified asphalt tack coat between each lift or layer of full depth asphaltic concrete and sand asphalt bases and on surface of bases where asphaltic concrete paving will be constructed. 3. Apply tack coat in accordance with Mn DOT Specifications. 4. Apply at minimum rate of 0.05 gal per sq. yd of surface. 5. Allow drying until at proper condition to receive paving. 3.3 ASPHALTIC CONCRETE PLACEMENT A. Place asphaltic concrete mixture on completed compacted subgrade surface, spread, and strike off. All pavements shall be placed in accordance with the maximum density method as described in Mn/DOT Specification 2360.6B. B. Whenever possible, spread pavement by finishing machine; however, inaccessible or irregular areas may be placed by hand methods. Spread hot mixture uniformly to required depth with hot shovels and rakes. After spreading, carefully smooth hot mixture to remove segregated course aggregate and rake marks. Rakes and lutes used for hand spreading shall be type designed for use on asphalt mixtures. Do not dump loads faster that they can be properly spread. Workers shall not stand on, loose mixture while spreading. C. Paving Machine Placement: Apply successive lifts of asphaltic concrete in transverse directions with surface course placed parallel to flow of traffic. Place asphaltic paving in typical strips not less than 10' -0" wide. Asphal- tic concrete pavement, including base and surface course, shall be placed in two or more equal lifts. Each lift shall be from 1 to 3 inches thick. D. Joints: Make joints between old and new pavements, or between successive days and work in manner that will provide continuous bond between adjoining work. Construction joints shall have same texture, density, and smoothness as other sections of asphaltic concrete course. Clean contact surfaces of joints and apply tack coat. 3.4 ROLLING AND COMPACTION A. After being spread, mixture shall be compacted by rolling as soon as it will bear the weight of rollers without un- due displacement. Number, weight, types of rollers, and sequences of rolling operations shall be such that the re- 02740-3 Wal -Mart Expansion Store No. 1861 -01, Oak Park Heights, Minnesota Revision Date: July 1, 2005 quired density and surface are consistently attained while the mixture is in workable condition_ A pneumatic roller shall be used for either the breakdown or intermediate rolling. B. Compact mixture with hot hand tampers or vibrating plate compactors in areas inaccessible to rollers. C. Breakdown Rolling: Perform breakdown or initial rolling immediately following rolling of joints and outside edge. Check surface after breakdown rolling and repair displaced areas by loosening and filling with hot material. D. Second Rolling: Follow breakdown rolling as soon as possible while mixture is hot. Continue second rolling until mixture has been thoroughly compacted as follows: 1. Average Density: 96 percent of reference laboratory density according to AASHTO T 245 (D1556), but not less than 94 percent nor greater than 100 percent. E. Finish Rolling: Perform finish rolling while mixture is still warm enough for removal of roller marks. Continue rolling until roller marks are eliminated and course has attained maximum density. F. Patching: Remove and replace paving areas mixed with foreign materials and defective areas. Cut out such areas and fill with fresh, hot asphaltic concrete. Compact by rolling to maximum surface density and smoothness. G. Protection: After final rolling, do not permit vehicular traffic on pavement until it has cooled and hardened. Erect barricades to protect paving from traffic until mixture has cooled enough not to become marked. Any masked or marred finish surfaces shall be repaired or smoothed. 3.5 JOINTS A. General 1. Place each asphaltic paving layer as continuous as possible to keep the number of joints to a minimum. Create joints between old and new pavement, between successive days work, and where the mixture has become cold (less than 140 degrees F). Make these joints in such a manner as to create a continuous bond between the old and new pavement construction courses. 2. Offset joint of successive courses by at least 6 inches. B. Transverse Joints: If placing of material is discontinued or if material in place becomes cold, make a joint running perpendicular to the direction traveled by the paver. Before placement continues, trim the edge of the previously placed pavement to a straight line perpendicular to the paver and cut back to expose an even vertical surface for the full thickness of the course. When placement continues, position the paver on the transverse joint so that suffi- cient hot mixture will be spread in order to create a joint after rolling that conforms to the required smoothness. If the temperature of the previously placed pavement material drops below 140 degrees F before paving is resumed, give the exposed vertical face a thin coat of liquid asphalt just before paving is continued. C. Longitudinal Joints: Coat longitudinal joints that are not completed before the previously laid mixture has cooled to a temperature below 140 degrees F, with liquid asphalt just before paving is continued. 3.6 FIELD QUALITY CONTROL A. Field quality control tests specified herein will be conducted by the Owner's Independent Testing Laboratory (ITL) at no cost to the Contractor in accordance with Section 01458.
