PROJECT

ENVIRONMENTAL COMMITMENTS The SDDOT is committed to protecting the environment and uses Environmental Commitments as a communication tool for the Engineer and Contractor to ensure that attention is given to avoid, minimize, and/or mitigate an environmental impact. Environmental commitments to various agencies and the public have been made to secure approval of this project. An agency with permitting authority can delay a project if identified environmental impacts have not been adequately addressed. Unless otherwise designated, the Contractor’s primary contact regarding matters associated with these commitments will be the Project Engineer. During construction, the Project Engineer will verify that the Contractor has met Environmental Commitment requirements. These environmental commitments are not subject to change without prior written approval from the SDDOT Environmental Office. Additional guidance on SDDOT’s Environmental Commitments can be accessed through the Environmental Procedures Manual found at: <https://dot.sd.gov/media/documents/EnvironmentalProceduresManual.pdf > For questions regarding change orders in the field that may have an effect on an Environmental Commitment, the Project Engineer will contact the Environmental Engineer at 605-773-3180 or 605-773-4336 to determine whether an environmental analysis and/or resource agency coordination is necessary. Once construction is complete, the Project Engineer will review all environmental commitments for the project and document their completion. COMMITMENT C: WATER SOURCE The Contractor will not withdraw water with equipment previously used outside the State of South Dakota or previously used in aquatic invasive species (AIS) positive waters within South Dakota without prior approval from the SDDOT Environmental Office. To prevent and control the introduction and spread of invasive species into the project vicinity, all equipment will be power washed with hot water (≥140 °F) and completely dried for a minimum of 7 days prior to subsequent use. South Dakota administrative rule 41:10:04:02 forbids the possession and transport of AIS; therefore, all attached dirt, mud, debris and vegetation must be removed and all compartments and tanks capable of holding standing water must be drained. This includes, but is not limited to, all equipment, pumps, lines, hoses and holding tanks. Action Taken/Required: The Contractor will obtain the necessary permits from the regulatory agencies such as the South Dakota Department of Environment and Natural Resources (DENR) and the United States Army Corps of Engineers (USACE) prior to water extraction activities. Additional information and mapping of water sources impacted by Aquatic Invasive Species in South Dakota can be accessed at: < http://sdleastwanted.com/maps/default.aspx > < South Dakota Administrative Rule 41:10:04 Aquatic Invasive Species: https://sdlegislature.gov/rules/DisplayRule.aspx?Rule=41:10:04 > COMMITMENT E: STORM WATER Construction activities constitute less than 1 acre of disturbance. Action Taken/Required: At a minimum and regardless of project size, appropriate erosion and sediment control measures must be installed to control the discharge of pollutants from the construction site.

COMMITMENT H: WASTE DISPOSAL SITE The Contractor will furnish a site(s) for the disposal of construction and/or demolition debris generated by this project. Action Taken/Required: Construction and/or demolition debris may not be disposed of within the Public ROW. The waste disposal site(s) will be managed and reclaimed in accordance with the following from the General Permit for Construction/Demolition Debris Disposal Under the South Dakota Waste Management Program issued by the Department of Environment and Natural Resources. The waste disposal site(s) will not be located in a wetland, within 200 feet of surface water, or in an area that adversely affects wildlife, recreation, aesthetic value of an area, or any threatened or endangered species, as approved by the Environmental Office and the Project Engineer. If the waste disposal site(s) is located such that it is within view of any ROW, the following additional requirements will apply: 1. Construction and/or demolition debris consisting of concrete, asphalt

concrete, or other similar materials will be buried in a trench separate from wood debris. The final cover over the construction and/or demolition debris will consist of a minimum of 1 foot of soil capable of supporting vegetation. Waste disposal sites provided outside of the Public ROW will be seeded in accordance with Natural Resources Conservation Service recommendations. The seeding recommendations may be obtained through the appropriate County NRCS Office. The Contractor will control the access to waste disposal sites not within the Public ROW with fences, gates, and placement of a sign or signs at the entrance to the site stating, No Dumping Allowed.

2. Concrete and asphalt concrete debris may be stockpiled within view of the

ROW for a period not to exceed the duration of the project. Prior to project completion, the waste will be removed from view of the ROW or buried, and the waste disposal site reclaimed as noted above.

The above requirements will not apply to waste disposal sites that are covered by an individual solid waste permit as specified in SDCL 34A-6-58, SDCL 34A-6-1.13, and ARSD 74:27:10:06. Failure to comply with the requirements stated above may result in civil penalties in accordance with South Dakota Solid Waste Law, SDCL 34A-6-1.31. Cost associated with furnishing waste disposal site(s), disposing of waste, maintaining control of access (fence gates, and signs), and reclamation of the waste disposal site(s) will be incidental to the various contract items.

COMMITMENT I: HISTORIC PRESERVATION OFFICE CLEARANCES State Historic Preservation Office (SHPO or THPO) concurrence has not been obtained for this project. Action Taken/Required: All earth disturbing activities not designated within the plans require a cultural resource review prior to scheduling the pre-construction meeting. This work includes but is not limited to: Contractor furnished material sources, material processing sites, stockpile sites, storage areas, plant sites, and waste areas. The Contractor will arrange and pay for a record search and when necessary, a cultural resource survey. The Contractor has the option to contact the state Archaeological Research Center (ARC) at 605-394-1936 or another qualified archaeologist, to obtain either a records search or a cultural resources survey. A record search might be sufficient for review if the site was previously surveyed; however, a cultural resources survey may need to be conducted by a qualified archaeologist. The Contractor will provide ARC with the following: a topographical map or aerial view in which the site is clearly outlined, site dimensions, project number, and PCN. If applicable, provide evidence that the site has been previously disturbed by farming, mining, or construction activities with a landowner statement that artifacts have not been found on the site. The Contractor will submit the cultural resources survey report to SDDOT Environmental Office, 700 East Broadway Avenue, Pierre, SD 57501-2586. SDDOT will submit the information to the appropriate SHPO/THPO. Allow 30 Days from the date this information is submitted to the Environmental Engineer for SHPO/THPO review. In the event of an inadvertent discovery of human remains, funerary objects, or if evidence of cultural resources is identified during project construction activities, then such activities within 100 feet of the inadvertent discovery will immediately cease and the Project Engineer will be immediately notified. The Project Engineer will contact the SDDOT Environmental Office, who will contact the appropriate SHPO/THPO within 48 hours of the discovery to determine an appropriate course of action. The Contractor is responsible for obtaining any additional permits and clearances for Contractor furnished material sources, material processing sites, stockpile sites, storage areas, plant sites, and waste areas that affect wetlands, threatened and endangered species, or waterways. The Contractor will not utilize a site known or suspected of having contaminated soil or water. The Contractor will provide the required permits and clearances to the Project Engineer at the preconstruction meeting.

PROJECT

SEQUENCE OF OPERATIONS The Contractor will use the sequence of operations listed below. 1. The Contractor will jet clean and/or clean ditch back to the original profile to

create positive drainage. 2. The Contractor will dispose sediment and debris from ditch cleanouts in

accordance with the Environmental Commitments. 3. Erosion control blankets will be placed according to the plans. UTILITIES The Contractor will contact the involved utility companies through South Dakota One Call (1-800-781-7474) prior to starting work. It will be the responsibility of the Contractor to coordinate work with the utility owners to avoid damage to existing facilities. Utilities are not planned to be affected on this project. If utilities are identified near the improvement area through the SD One Call process as required by South Dakota Codified Law 49-7A and Administrative Rule Article 20:25; the Contractor will contact the Project Engineer to determine if project changes are necessary to avoid utility impacts. CULVERT CLEANOUT The Contractor will inspect the culvert locations and determine the necessary method for cleaning out the culverts. Cleaning should be accomplished with high pressure water jet, vacuum trucks, reaming, push buckets, pull buckets, or brushing. If the culvert is large enough, personnel or equipment such as skid steer loaders can remove debris. The cleaning method must be approved by the Engineer. Cleaning will be conducted in the direction of drainage, as indicated in the plans. Each culvert will be cleaned so the bottom of the pipe is visible throughout its length to re-establish the flow line. The culvert will be cleaned to the satisfaction of the Engineer. When culvert cleanout methods are used that produce downstream discharge, the Contractor will implement appropriate temporary erosion control measures prior to culvert cleaning to prevent discharges beyond the project boundaries. Temporary erosion control methods will be approved by the Engineer. The Engineer will identify areas in the vicinity of culvert ends where ditch reprofiling/reshaping is needed to restore ditch flow. The Contractor will shape and reseed the ditch areas identified by the Engineer. All sediment and debris removed from the culvert will be disposed of or reused for erosion repair by the Contractor, as approved by the Engineer. Cost associated with cleanout of the existing culvert, temporary erosion control measures, and the removal of sediment and debris, will be included in the contract unit price per each for Cleanout Pipe Culvert.

REPROFILING DITCH The following ditches will be cleaned out to allow drainage through the ditch.

• North side of SD 44 – MRM 400.69 (3.0 stations) • North side of SD 34 – MRM 366.36 (1.0 station) • North side of SD 34 – MRM 365.79 (10.0 stations) The total estimated length of ditch cleanout is 1,400 feet (14 stations). These locations will be restored to the existing typical ditch section. Areas to be cleaned out will be staked by the Engineer prior to clean out. Disturbed areas will be restored to the satisfaction of the Engineer. Disturbed areas will be seeded by the Contractor. Cost for this work, including labor and equipment necessary to remove and dispose of the silt and vegetation and reshape the ditch will be included in the contract unit price per station for Reprofiling Ditch. Cost for seeding and mulching will be included in the contract unit prices for the respective items. CONTRACTOR FURNISHED TOPSOIL It is anticipated that a larger volume of topsoil will be needed for the new grade than can be salvaged from the existing grade. The Contractor will be required to furnish and place 4 inches of topsoil on roadway inslopes and areas as determined by the Engineer during construction. Contractor furnished topsoil will be free from stones, coarse gravel, or similar objects larger than 3/4 inch in diameter. Brush, stumps, roots, wood, objectionable weeds, liter, or any other material which may be harmful to plant growth will not be allowed. Organic material will be decomposed. The estimated amount of topsoil to be furnished and placed is as follows:

PROJECT

WATER FOR VEGETATION Water for vegetation consists of applying water to seeded areas to enhance germination and/or root growth. When watering, use the following guidelines: Immediately after seeding:

• Keep the topsoil moist but not excessively wet until the seed has germinated.

• Water a minimum of 3 days a week for 2 weeks preferably watering 2 or 3

times a day in small quantities. • Use fine spray and low pressure to avoid topsoil wash and to prevent

uncovering buried seeds. After emergence:

• Topsoil will be kept thoroughly moistened by sprinkling, as necessary, for 6 weeks. After the 6-week period, an inspection will be made to determine if grass is established enough to suspend watering. Continue watering until grass has been thoroughly established.

• Never apply water at a rate faster than the topsoil can absorb. • Water during early morning hours or early evening hours.

• Do not water when rain is forecasted for the area.

• If rainfall occurs, suspend watering according to rainfall amount.

An estimated 10 Gallons of water per square yard of seeding area was used to compute the quantity for Water for Vegetation. Cost for furnishing and applying the water including hauling, material, equipment, labor, and incidentals necessary will be included in the contract unit price per MGal for Water for Vegetation. FIBER MULCHING Fiber mulch will be applied in a separate operation following permanent seeding. An additional 2% by weight of tackifier will be added to the fiber mulch product selected from the approved product list. If the product selected has guar gum tackifier included, then the additional 2% of tackifier will be guar gum. If the product selected has synthetic tackifier included, then the additional 2% of tackifier will be synthetic. Fiber mulch will be applied at the rate of 3,000 pounds per acre. The Contractor will allow the fiber mulch to cure a minimum of 18 hours prior to watering or any storm event to ensure proper cohesion between the soil and fiber particles. The fiber mulch provided will be from the approved product list. The approved product list for fiber mulch may be viewed at the following internet site: http://apps.sd.gov/HC60ApprovedProducts/main.aspx Cost for additional tackifier added to the fiber mulch including labor, equipment, and materials will be incidental to the contract unit price per pound or ton for Fiber Mulching.

SOIL STABILIZER An estimated quantity of 3,163 SqYd of soil stabilizer has been included in the Estimate of Quantities. The soil stabilizer will be applied on permanently seeded areas and areas deemed necessary by the Engineer. The Contractor will apply soil stabilizer in accordance with the manufacturer’s application instructions and at the rate specified in the list of approved soil stabilizers. Wood fiber mulch that contains a green dye will be mixed with the soil stabilizer to be used as a tracer when the soil stabilizer is applied hydraulically. Wood fiber mulch will be added at a rate of 300 pounds per acre to all of the approved soil stabilizers listed in the table except for the Pam-12 Plus product. The wood fiber mulch will be a 100% wood fiber product and does not need to contain a tackifier. Cost for furnishing and applying the soil stabilizer including wood fiber mulch, hauling, materials, equipment, labor, and incidentals necessary will be included in the contract unit price per square yard for Soil Stabilizer. The soil stabilizer will be from the list below or an approved equal:

The contractor will be allowed to reduce one lane of traffic on I229, I29 and I90 in any direction from the hours of 9:00AM to 4:00PM Monday thru Friday. From 6:00AM to 9:00AM and from 4:00PM to 6:00PM (Peak Hours) Monday thru Friday all lanes of traffic must be maintained on I229, I29 and I90 in all directions. From 9:00AM to 4:00PM Monday thru Friday 2 lanes of traffic must be maintained on I29 northbound and southbound; 1 lane must be maintained for I-229 northbound and southbound and 1 lane must be maintained for I-90 eastbound and westbound. On Saturday’s and Sunday’s all lanes of traffic must be maintained on I229, I29 and I90 in all directions. All temporary traffic control sign locations will be set in the field by the Contractor and verified by the Engineer prior to installation. Portable sign supports will not be located on sidewalks, bicycle facilities, or other areas designated for pedestrian or bicycle traffic. All construction operations will be conducted in the general direction of traffic movement. If there is a discrepancy between the traffic control plans, standard plates, and the MUTCD, whichever is more stringent will be used, as determined by the Engineer. Unless otherwise stated in these plans, work will not be allowed during hours of darkness. All haul trucks will be equipped with an additional flashing amber light that is visible from the backside of the haul truck. Cost for the flashing amber lights will be incidental to the various related contract items.

FLAGGING Operations will be conducted so that the traveling public will not have to wait longer than 15 minutes at the flagger station.

The signs illustrated are not required if the work space is behind a barrier, more than 2 feet behind the curb, or 15 feet or more from the edge of any roadway.

The signs illustrated will be used where there are distracting situations; such as: vehicles parked on shoulder, vehicles accessing the work site via the highway, and equipment traveling on or crossing the roadway to perform work operations.

The ROAD WORK AHEAD sign may be replaced with other appropriate signs, such as the SHOULDER WORK sign. The SHOULDER WORK sign may be used for work adjacent to the shoulder.

* If the work space is on a divided highway, an advance warning sign should also be placed on the left side of the directional roadway.

For short term, short duration, or mobile operations, all signs and channelizing devices may be eliminated if a vehicle with an activated flashing or revolving yellow light is used.

*In situations where multiple work locations in a limited distance make it practical to place stationary signs, the distance between the advance warning sign and the work should not exceed 5 miles.

The ROAD WORK NEXT xx MILES sign may be used instead of the ROAD WORK AHEAD sign if the work locations occur over a distance of more than 2 miles.

Arrow board is required for intermittently and continuously moving mobile operations when work exceeds 1 hour.

**If the work space is on a divided highway, an advance warning sign should also be placed on the left side of the directional roadway.

In situations where the distance between the advance warning signs and the work is 2 miles to 5 miles, a Supplemental Distance plaque should be used with the ROAD WORK AHEAD sign.

All costs associated with the traffic control for mobile operation including signs, arrow boards and equipment will be incidental to the contract lump sum price for "Traffic Control, Miscellaneous".

Flagger

■ Channelizing Device

For low-volume traffic situations with short work zones on straight roadways where the flagger is visible to road users approaching from both directions, a single flagger may be used.

The ROAD WORK AHEAD and the END ROAD WORK signs may be omitted for short duration operations (1 hour or less).

For tack and/or flush seal operations, when flaggers are not being used, the FRESH OIL sign (W21-2) will be displayed in advance of the liquid asphalt areas.

Flashing warning lights and/or flags may be used to call attention to the advance warning signs.

The channelizing devices will be drums or 42" cones.

Channelizing devices are not required along the centerline adjacent to work area when pilot cars are utilized for escorting traffic through the work area. z-ow

~!!OM OVO!I ON3

Channelizing devices and flaggers will be used at intersecting roads to control intersecting road traffic as required.

The buffer space should be extended so that the two-way traffic taper is placed before a horizontal or vertical curve to provide adequate sight distance for the flagger and queue of stopped vehicles.

The length of A may be adjusted to fit field conditions.

l&:J PIPE END DETAIL

Prior to placement of the erosion control blanket, the areas will be properly prepared, shaped, seeded, and fertilized.

Erosion control blanket will be unrolled in the direction of the flow of water when placed in ditches and on slopes. The upslope end of the erosion control blanket will be buried in a trench 6" wide by 6" deep. There will be at least a 6" overlap wherever one roll of erosion control blanket ends and another begins, with the upslope erosion control blanket placed on top of the downslope erosion control blanket.

The erosion control blanket will be pinned to the ground according to the manufacturer's installation recommendations.

After the placement of the erosion control blanket, the Contractor will fine grade along all edges of the blanket to maintain a uniform slope adjacent to the blanket and level any low spots which might prevent uniform and unrestricted flow of side drainage directly onto the erosion control blanket.

All ditch sections will be shaped when installing the erosion control blanket. All costs for shaping the ditches will be incidental to the contract unit price per foot for "Shaping for Erosion Control Blanket".

1------PR_O_JE_CT ___ ---I SHEET


At cut or fill slope installations, wattles will be installed along the contour and perpendicular to the water flow.

At ditch installations, point A must be higher than point B to ensure that water flows over the wattle and not around the ends.

The Contractor will dig a 3" to 5" trench, install the wattle tightly in the trench so that daylight can not be seen under the wattle, and then compact the soil excavated from the trench against the wattle on the uphill side. See Detail B.

The stakes will be 1 "x2" or 2"x2" wood stakes, however, other types of stakes such as rebar may be used only if approved by the Engineer. The stakes will be placed 6" from the ends of the wattles and the spacing of the stakes along the wattles will be 3' to 4'.

Where installing running lengths of wattles, the Contractor will butt the second wattle tightly against the first and will not overlap the ends. See Detail C.

The Contractor and Engineer will inspect the erosion control wattles in accordance with the storm water permit. The Contractor will remove, dispose, or reshape the accumulated sediment when necessary as determined by the Engineer.

Sediment removal , disposal, or necessary shaping will be as directed by the Engineer. All costs for removing accumulated sediment, disposal of sediment, and necessary shaping will be incidental to the contract unit price per cubic yard for "Remove Sediment".

All costs for furnishing and installing the erosion control wattles including labor, equipment, and materials will be incidental to the contract unit price per foot for the corresponding erosion control wattle contract item.

All costs for removing the erosion control wattle from the project including labor, equipment, and materials will be incidental to the contract unit price per foot for "Remove Erosion Control Wattle".
