About this file

Written by GovTribe AI · Feb 24, 2026

This is a design and construction document package for the rehabilitation of Cedar Pass Lodge Cabin Road in Badlands National Park, Interior, South Dakota. The project involves demolition of existing gravel surfacing, construction of a new 6-inch gravel-surfaced roadway, installation of concrete valley gutters, grading and drainage improvements, an earthen berm, and comprehensive erosion control measures. The design includes approximately 37 stations of new road construction with associated utility coordination, drainage channel development extending approximately 1.2 miles, and storm water pollution prevention planning.

The scope encompasses site preparation including stabilized construction entrance installation, removal and stockpiling of existing materials at an NPS-designated soil waste site, placement of imported fill for berm construction in lifts compacted to 95% maximum dry density per ASTM D698, installation of erosion control blankets and silt fencing around perimeter areas, seeding and hydromulching of disturbed areas, and maintenance of temporary erosion controls throughout construction. The contractor is responsible for obtaining the stormwater permit from the South Dakota Department of Agriculture & Natural Resources, conducting all inspections and modifications to the Storm Water Pollution Prevention Plan, and submitting notice of termination upon final project stabilization. Control survey data is provided with horizontal datum NAD83 South Dakota South and vertical datum NAVD88, with nine survey control points established by 5/8-inch rebar with caps.

Wetland Avoidance Will construction and/or erosion and sediment controls impinge on regulated wetlands? Yes No If yes, the structural and erosion and sediment controls have been included in the total project wetland impacts and have been included in the 404 permit process with the USACE.

5.3 (6): PROCEDURES FOR INSPECTIONS

• Inspections will be conducted at least once every 7 days or once every 14 calendar days and within 24 hours of precipitation that exceeds 0.25 inches or snowmelt that generates runoff.

• All controls will be maintained in good working order. Necessary repairs will be initiated within 24 hours of the site inspection report.

• Silt fence will be inspected for depth of sediment and for tears to ensure the fabric is securely attached to the posts and that the posts are well anchored.

Sediment buildup will be removed from the silt fence when it reaches 1/3 of the height of the silt fence.

• Sediment basins and traps will be checked. Sediment will be removed when depth reaches approximately 50 percent of the structure’s capacity, and at the conclusion of the construction.

• Check dams will be inspected for stability. Sediment will be removed when depth reaches ½ the height of the dam.

• All seeded areas will be checked for bare spots, washouts, and vigorous growth free of significant weed infestations.

• Inspection and maintenance reports will be prepared on the erosion control inspection form for each site inspection, this form will also be used to document changes to the SWPPP. A copy of the completed inspection form will be filed with the SWPPP documents.

• The Contractor is responsible for inspections. Maintenance and repair activities are the responsibility of the Contractor. The Contractor will complete the inspection and maintenance reports and distribute copies per the instructions on the erosion control inspection form.

5.3 (7): POST CONSTRUCTION STORMWATER MANAGEMENT

Stormwater management will be handled by temporary controls outlined in “DESCRIPTION AND MAINTENANCE OF CONTROL MEASURES” above, and any permanent controls needed to meet permanent stormwater management needs in the post construction period will be shown in the plans and noted as permanent.

5.3 (8): POLLUTION PREVENTION PROCEDURES

5.3 (8a): Spill Prevention and Response Procedures Material Management Housekeeping

• Only needed products will be stored on-site by the Contractor.

• Except for bulk materials the contractor will store all materials under cover and/or in appropriate containers.

• Products must be stored in original containers and labeled.

• Material mixing will be conducted in accordance with the manufacturer’s recommendations.

• When possible, all products will be completely used before properly disposing of the container off-site.

• The manufacturer’s directions for disposal of materials and containers will be followed.

• The Contractor’s site superintendent will inspect materials storage areas regularly to ensure proper use and disposal.

• Dust generated will be controlled in an environmentally safe manner.

SWPPP CHECKLIST

Hazardous Materials

• Products will be kept in original containers unless the container is not resealable and provide secondary containment as applicable.

• Original labels and material safety data sheets will be retained in a safe place to relay important product information.

• If surplus product must be disposed of, manufacturer’s label directions for disposal will be followed.

• Maintenance and repair of all equipment and vehicles involving oil changes, hydraulic system drain down, de-greasing operations, fuel tank drain down and removal, and other activities which may result in the accidental release of contaminants will be conducted on an impervious surface and under cover during wet weather to prevent the release of contaminants onto the ground.

• Wheel wash water will be collected and allowed to settle out suspended solids prior to discharge. Wheel wash water will not be discharged directly into any stormwater system or stormwater treatment system.

• Potential pH-modifying materials such as: bulk cement, cement kiln dust, fly ash, new concrete washings, concrete pumping, residuals from concrete saw cutting (either wet or dry), and mixer washout waters will be collected on site and managed to prevent contamination of stormwater runoff.

Spill Control Practices In addition to the previous housekeeping and management practices, the following practices will be followed for spill prevention and cleanup if needed.

• For all hazardous materials stored on site, the manufacturer’s recommended methods for spill cleanup will be clearly posted. Site personnel will be made aware of the procedures and the locations of the information and cleanup supplies.

• Appropriate cleanup materials and equipment will be maintained by the Contractor in the materials storage area on-site. As appropriate, equipment and materials may include items such as brooms, dust pans, mops, rags, gloves, goggles, kitty litter, sand, sawdust, and plastic and metal trash containers specifically for cleanup purposes.

• All spills will be cleaned immediately after discovery and the materials disposed of properly.

• The spill area will be kept well ventilated and personnel will wear appropriate protective clothing to prevent injury from contact with a hazardous substance.

• After a spill a report will be prepared describing the spill, what caused it, and the cleanup measures taken. The spill prevention plan will be adjusted to include measures to prevent this type of spill from reoccurring, as well as clean up instructions in the event of reoccurrences.

• The Contractor’s site superintendent, responsible for day-to-day operations, will be the spill prevention and cleanup coordinator.

Spill Response The primary objective in responding to a spill is to quickly contain the material(s) and prevent or minimize migration into stormwater runoff and conveyance systems. If the release has impacted on-site stormwater, it is critical to contain the released materials on-site and prevent their release into receiving waters. If a spill of pollutants threatens stormwater or surface water at the site, the spill response procedures outlined below must be implemented in a timely manner to prevent the release of pollutants.

• The Contractor’s site superintendent will be notified immediately when a spill or the threat of a spill is observed. The superintendent will assess the situation and determine the appropriate response.

• If spills represent an imminent threat of escaping erosion and sediment controls and entering receiving waters, personnel will be directed to respond immediately to contain the release and notify the superintendent after the situation has been stabilized.

• Spill kits containing appropriate materials and equipment for spill response and cleanup will be maintained by the Contractor at the site.

• If oil sheen is observed on surface water (e.g. settling ponds, detention ponds, swales), action will be taken immediately to remove the material causing the sheen. The Contractor will use appropriate materials to contain and absorb the spill. The source of the oil sheen will also be identified and removed or repaired as necessary to prevent further releases.

• If a spill occurs the superintendent or the superintendent’s designee will be responsible for completing the spill reporting form and for reporting the spill to SDDENR.

• Personnel with primary responsibility for spill response and cleanup will receive training by the Contractor’s site superintendent or designee. The training must include identifying the location of the spill kits and other spill response equipment and the use of spill response materials.

• Spill response equipment will be inspected and maintained as necessary to replace any materials used in spill response activities.

5.3 (8b): WASTE MANAGEMENT PROCEDURES Waste Disposal

• All liquid waste materials will be collected and stored in approved sealed containers. All trash and construction debris from the site will be deposited in the approved containers. Containers will be serviced as necessary, and the trash will be hauled to an approved disposal site or licensed landfill. All onsite personnel will be instructed in the proper procedures for waste disposal and notices stating proper practices will be posted. The Contractor is responsible for ensuring waste disposal procedures are followed.

Hazardous Waste

• All hazardous waste materials will be disposed of in a manner specified by local or state regulations or by the manufacturer. Site personnel will be instructed in these practices, and the Contractor will be responsible for seeing that these practices are followed.

Sanitary Waste

• Portable sanitary facilities will be provided on all construction sites. Sanitary waste will be collected from the portable units which must be secured to prevent tipping and serviced in a timely manner by a licensed waste management Contractor or as required by any local regulations.

• Petroleum Products All on-site vehicles will be monitored for leaks and receive regular preventive maintenance to reduce the chance of leakage. Petroleum products will be stored in tightly sealed containers which are clearly labeled.

• Fertilizers Fertilizers will be applied only in the amounts specified or recommended by the supplier. Once applied, fertilizers will be worked into the soil to limit the exposure to stormwater. Fertilizers will be stored in an enclosed area. The contents of partially used fertilizer bags will be transferred to sealable containers to avoid spills.

• Paints All containers will be tightly sealed and stored when not required for use. The excess will be disposed of according to the manufacturer’s instructions and any applicable state and local regulations.

• Concrete Trucks Contractors will provide designated truck washout facilities on the site. These areas must be self-contained and not connected to any stormwater outlet of the site. Upon completion of construction, the area at the washout facility will be properly stabilized.
