BASE BID

• Memorial Arch – Tree Removal. All trees and shrubs within 20 feet from the edge of the existing tree/vegetation line shall be removed. Branches of remaining trees shall be pruned back so that no branches are extending toward or touching the Memorial Arch. Tree stumps shall be treated immediately with herbicide to prevent regrowth. All debris shall be removed and disposed of properly. See map specifying locations (yellow shaded areas).

Stumps shall be treated immediately after cutting with approved herbicide to prevent regrowth. Cut vegetation shall be left on site where it lies, or slash piled to be burned. Woody debris shall be cut into small enough pieces and piled in designated areas, resulting in a low profile with no branches or stems standing at a height more than 12-18 inches and providing a 25 feet buffer from mowing zones/lines. Cut vegetation shall be cleared on foot with hand tools (saws, pruners, chainsaws, brush cutters); tracked vehicles may be permitted in some areas in consultation with COR.

o Grasses - Areas of Johnson Grass within South Loop shall be cut and sprayed with approved herbicide to prevent regrowth. Locations shall be selected in the future in consultation with park staff. Estimated area: 10 acres.

• Illinois/Shirley House Loop – Tree removal and Treatment of Johnson Grass.

o Trees - All trees (locusts) and shrubby vegetation shall be removed within Illinois/Shirley

House Loop (see map for boundary). Trees shall be cut as close to the ground as possible without disturbing the soil. Stumps shall be treated immediately after cutting with approved herbicide to prevent regrowth. Cut vegetation shall be left on site where it lies, or slash piled to be burned.

• North of Graveyard Rd (Site C & D) - Tree removal and Treatment of Johnson Grass. All trees and herbaceous materials within 25 feet of the outer edge of the vegetation cluster shall be removed. Trees shall be cut as close to the ground as possible without disturbing the soil. Stumps shall be treated immediately after cutting with approved herbicide to prevent regrowth. Cut vegetation shall be left on site where it lies, or slash piled to be burned. Woody debris shall be cut into small enough pieces and piled in designated areas, resulting in a low profile with no branches or stems standing at a height more than 12-18 inches and providing a 25feet buffer from mowing zones/lines. Cut vegetation shall be cleared on foot with hand tools (saws, pruners, chainsaws, brush cutters); tracked vehicles may be permitted in some areas in consultation with COR. See map showing Site C & D.

Activities shall be timed to minimize any impacts on wildlife species (November/March) and wetlands (i.e., during dry periods). There shall be no ground disturbance of any type. The NPS intends to conduct prescribed burns at this site during January/February; preferred start/completion date for this area is November.

Select areas of Johnson Grass within South Loop and along the park tour road shall be cut and sprayed with approved herbicide to prevent regrowth. Estimated area: 10 acres.

BID ADDITIVE 1

• 50 hazardous limb pruning – Contractor shall be on-call to remove up to 50 hazardous limbs throughout the park throughout the duration of the contract. All debris to be removed from the park.

• 20 hazardous/downed tree removals – Contractor shall be on-call to remove up to 20 hazardous and downed trees throughout the park throughout the duration of the contract.

BID ADDITIVE 2

• North of Graveyard Rd (Site C & D) – Additional tree removal. All trees and herbaceous materials within an additional 25 feet of the outer edge of the vegetation cluster shall be removed.

Contractor shall follow the same procedures outlined above for tree removal and Johnson grass treatment.

C. Herbicides:

Certified applicators shall use hand sprayers or brushes to apply NPS-approved herbicide to entire cut surface of stumps; no broadcast spraying allowed.

Since some project sites include herbicide application near wetland sites, only aquatic labeled herbicides will be approved for those areas. Glyphosate or Imazapyr aquatic-based herbicides are effective for cut-stump method on woody vegetation at 20-25% active ingredient mixed with water and small amount of dye spray indicator. The Contractor shall mix the herbicides with a colorant for each batch mixed, added and coordinated with the NPS before application (dye or colorant, to show what has been treated). Cut-stump treatments shall not occur when there is a 60% or greater chance of rain at any point within the next 48 hours according to the local forecast for Vicksburg, MS.

Recommended Herbicides:

• Habit and Polaris are the main aquatic labeled Imazapyr products

• Rodeo is an aquatic labeled glyphosate

• Outrider – Sulfosulfuron – used to kill Johnson grass without harming other grasses

• Garlon 4 Ultra – Triclopyr – used to kill trees without harming grasses

Note: NPS REQUIRES PRE-APPROVAL OF HERBICIDE BEFORE PURCHASE. DO NOT ACQUIRE OR DELIVER Herbicides until the NPS has informed the contractor to proceed with acquisition of the approved herbicides. Use form CM-16 and the IPM Pesticide Purchase Log to submit the approved products being acquired by the Contractor. The returned CM-16 will be documentation for the contractor to proceed with acquisition of the material.

In addition, contractor must report herbicide type, amount of herbicide used, and acreage covered to NPS at end of project but must make readily available for inspection to avoid a stop work notice. The contractor shall utilize the IPM Pesticide Applicator Use Log provided by the NPS for this documentation via the CM-16 form submission. The contractor shall follow all safety guidelines on herbicide labels, including recommended use of personal protective equipment.

D. Cleanup/Completion. Before delivery to park and before and after completion of each designated project area, contractors’ equipment and clothing should be brushed or washed free of any vegetative materials (seeds, foliage, etc.) before moving to the next area or removing equipment from the park. The Contractor shall ensure this is done to prevent the spread of non-native plant species throughout the park.

E. Safety. Appropriate OSHA and NPS Safety Regulations and Policies shall be adhered to including wearing personal protective equipment, making available first aid equipment, and posting pertinent safety information. Dial 911 in case of emergency. Unsafe operations shall be halted until corrective action is taken by Contracting Officer (CO), Contracting Officer Representative (COR), Facility Manager, Resource Manager, or Park’s Safety Officer. This halt shall be at no additional expense to the government.

Traffic is generally one-way; follow traffic patterns. Vehicles and equipment should not impede the normal flow of visitation through the park. Work with park staff to determine proper parking/staging locations for each work area.

Submit an acceptable documented project specific safety plan (SSP) prior to a notice to proceed (resume). Include a cool down period of 15 minutes after shutting off equipment before refueling.

Submit in writing designated company safety officer/coordinator that will be on site for the duration of the project with the responsibility and authority for ensuring safe work practices are being carried out per the approved SSP.

Contractor shall only utilize a Department of Transportation (DOT) metal gas can for transporting fuel in/out of the park. Plastic gas cans are prohibited.

Submit an equipment/tool list of all powered equipment to be used on site to include, make, model, condition, quantities, and include in the equipment list a gas funnel, gas can, electrical or fuel power tools, hoses, fire extinguisher, etc. All equipment must be in good working condition and must be inspected by the NPS before putting into use during a pre-inspection. All equipment shall have all safety guards and devices affixed and must remain in place while being utilized on the job site.
