Written by GovTribe AI · Feb 10, 2025

This is a set of engineering drawings and specifications prepared by SPN & Associates for the South Dakota Army National Guard's CFMO #467011 project to regrade and regravel unpaved organizational (ORG) lots at the Mitchell Complex in Mitchell, South Dakota. The project involves regrading and regraveling work on unpaved lots, including installation of concrete valley gutters, erosion control measures, silt fencing, straw wattles, and a cantilevered sliding gate. The drawings include detailed site plans, grading plans, and construction details for both north and south lots at the facility, with specific requirements for crushed concrete, salvaged gravel surfacing, and proper drainage.

The drawings provide comprehensive technical specifications including typical gravel surfacing sections, fence and gate details, erosion control measures, and a Storm Water Pollution Prevention Plan (SWPPP). Key quantities include 3" crushed concrete surfacing, 3" salvaged gravel, concrete valley gutters, chain link fencing, and various erosion control measures. The project requires coordination with existing site infrastructure including sanitary sewer lines, water lines, and other utilities. The drawings are certified by a Professional Engineer registered in South Dakota and include revisions dated 1/10/20.

vNon-Storm Water Discharges (5.4 10) The following non-storm water discharges are anticipated during the course of this project (The Contractor will check all that apply).

Ø Discharges from water line flushing.

Ø Pavement wash-water, where no spills or leaks of toxic or hazardous materials have occurred.

Ø Uncontaminated ground water associated with dewatering activities.

vSpill Prevention (5.4 8) Ø 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 in appropriate containers.

· Products shall be kept in their original containers with the original manufacture's label.

· Material mixing will be conducted in accordance with the manufacturer's recommendations.

· Whenever 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.

· Vegetation areas not essential to the construction project will be preserved and maintained as noted on the erosion control plans.

Hazardous Materials

· Products will be kept in original containers unless the container is not resealable.

· 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 storm water system or storm water treatment system.

· Potential pH-modifying materials such as: bulk cement, cement kiln dust, fly ash, new concrete washings, concrete pumping, and mixer washout waters will be collected on site and managed to prevent contamination of storm water runoff.

vMaterials Inventory (5.4 9.(a)-(c)) The following materials or substances are expected to be present on the site during the construction period. These materials will be handled as noted under the headings "EROSION AND SEDIMENT CONTROLS" and "SPILL PREVENTION" (The Contractor will check all that apply).

Ø Concrete and Portland Cement Ø Detergents Ø Paints Ø Metals Ø Bituminous Materials Ø Petroleum Based Products Ø Cleaning Solvents Ø Wood Ø Cure Ø Texture Ø Chemical Fertilizers Ø Herbicides Ø Diesel Exhaust Fluid Ø Other:

Ø Product Specific Practices (5.4 9) 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 recommended by the supplier. Once applied, fertilizers will be worked into the soil to limit the exposure to storm water. 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 areas on the site. These areas must be self contained and not connected to any storm water outlet of the site.

Upon completion of construction washout areas will be properly stabilized.

Ø Spill Control Practices (5.4 8) 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 clean up 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 booms, dust pans, mops, rags, gloves, goggles, kitty litter, sand, sawdust, and plastic and metal trash containers specifically for clean up 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. The contractor is responsible for ensuring that the site superintendent has had appropriate training for hazardous materials handling, spill management, and cleanup.

Ø Spill Response (5.4 8) The primary objective in responding to a spill is to quickly contain the material(s) and prevent or minimize migration into storm water runoff and conveyance systems. If the release has impacted on-site storm water, it is critical to contain the released materials on-site and prevent their release into receiving waters. If a spill of pollutants threatens storm water 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 SD

DANR.

Personnel with primary responsibility for spill response and clean up 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.

vSpill Notification (7.2 1.(a)-(i)) In the event of a spill, the contractor's site superintendent will make the appropriate notification(s), consistent with the following procedures:

Ø A reportable spill is a quantity of 25 gallons or more or any spill of oil which:

1) violates water quality standards, 2) produces a "sheen" on a surface water, or 3) causes a sludge or emulsion must be reported immediately to the National Response Center .

Ø Any spill of oil or hazardous substance to waters of the state must be reported immediately by telephone to the SD DANR.

vPost Construction Stormwater Management (5.4 7.(a)-(c))

Storm management will be handled by temporary controls outlined in "Description and maintenance of control measures" 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.

vInfeasibility Document (5.4 11)

If it is determined to be infeasible to comply with any of the requirements of the Stormwater Permit, the infeasibility determination must be thoroughly documented in the SWPPP.

vRequired SWPPP Modifications (5.6)

Ø Conditions Requiring SWPPP Modifications (5.6 1) The SWPPP must be modified, including the site map(s) in response to any of the following conditions.

When a new operator responsible for implementation of any part of the

SWPPP begins work on the site.

When changes to the construction plans, sediment and erosion control measures, or any best management practices on site that are no longer accurately reflected in the SWPPP. This includes changes made in response to corrective actions triggered by inspections.

To reflect areas on the site map where operational control has been transferred (including the date of the transfer) or has been covered under a new permit since initiating coverage under this general permit.

If inspections by site staff, local officials, SDDANR, or U.S. EPA determine that SWPPP modifications are necessary for compliance with the Stormwater Permit.

To reflect any revisions to applicable federal, state, or local requirements that affect the control measures implemented at the site.

If approved to reflect any changes in chemical water treatment systems or controls, including the use of a different water treatment chemical, age rates, different areas, or methods of application.

Ø Deadlines for SWPPP Modification (5.6 2) Any required revisions to…
