b. Stop Work: Cease alt activities in the area of discovery and protect the resources discovered. In the event the discovery represents human remains or any objects subject to the Native American Graves Protection and Repatriation Act (NAGPRA), the NPS wilt follow procedures outlined in NAGPRA regulations. This wilt require a stoppage of work in the area of work for a minimum of 30 calendar days. In the event of an inadvertent discovery of Cultural Resources, be prepared to stop work and continue in other areas.

1) The Contractor shalt plan, schedule, and execute the work to prevent stoppages at one area from stopping all work at the construction site.

2) Adjustments for Work Stoppage. See Federal Acquisition Regulations.

2. Natural Resource Protection:

a. Plant Condition Inventory: The Contractor and the Project Manager or designated representative, shalt perform an on-site inventory of trees and

NATURAL, CULTURAL & PHYSICAL RESOURCES PROTECTION 013550-9

other overall vegetation features within or near to the work limits. Project Manager

b. On-site inventory shall be scheduled in coordination with the pre- construction conference.

c. Access to work sites requiring travel through undeveloped areas outside the work limits must be approved by the Project Manager.

d. Provide temporary barriers (e.g., orange construction fence) to protect existing trees, plants and critical root zones that are designated to remain, but are: (1) within the construction limits; 2) on or just outside the construction limits; (3) within the clearing limits (i.e., the zone extending 5 feet beyond the staked construction limits); or (4) on, or just outside the clearing limit line.

Barriers shall be in place before construction begins.

e. Except in areas indicated on the drawings or specified to be cleared, the Contractor shall not remove, cut, deface, injure, or destroy resources including trees, shrubs, vines, grasses, topsoil, and landforms without approval. No ropes, cables, or guys shall be fastened to or attached to any trees for anchorage unless specifically authorized.

f. Removal of trees will be performed by YNP in advance of Contractor's work.

Should it be determined during the course of work that additional trees or tree roots require removal, Contractor shall notify the Project Manager who will coordinate an inspection and determination by the appropriate authorities whether to remove the tree or not.

g. After tree removal, large roots may remain in the ground. Contractor shall be responsible for carefully removing in-ground tree roots of removed trees to permit excavation, drilling, or other ground penetrating construction activities.

During tree root removal, do not use backhoes, chains, or other equipment in a manner that will harm roots of adjacent trees.

h. Minimize disturbance to tree trunks and root zones to prevent damage to trees.

i. Adjust trenches and other excavations to keep them beyond the drip line wherever possible.

1) Attempt to maintain the following minimum clearances between the edges of tree trunks and excavation:

for trees more than 30-inch-in-diameter 10 feet for trees between 15-inch and 30-inch-in-diameter 8 feet for trees less than 15-inch-in-diameter 5 feet

2) Adjust the survey line, as necessary to maintain required clearances.

a) Notify the Project Manager Project Manager of any proposed trenches or other excavations within the drip line of trees.

j. Steps to Mitigate Damage to Roots Due to Excavation:

1) A Take steps (as called for below) to mitigate damage to tree roots due to excavation, wherever the following circumstances apply:

a) Wherever excavation must take place within the drip line of oak trees regardless of diameter.

b) Wherever excavation must take place within the drip line of trees other than oaks, for all trees 12 inches or larger in diameter.

2) Trees which are anticipated to meet these criteria and therefore require steps to mitigate damage to roots due to excavation are shown on the drawings. Adjustments in trench alignment or other factors mayj

NATURAL, CULTURAL & PHYSICAL RESOURCES PROTECTION 0135 50-10

result in variations in which trees are affected. The Contractor shall accommodate these variations at no additional expense to the Government.

3) Following are the steps which are required to mitigate damage to roots due to excavation:

a) Excavate carefully where tree roots might be encountered.

Where roots 2 inches and larger are encountered, hand excavate as required to prevent damage to roots. Tunnel under roots to be saved, hand excavating as necessary.

b) Do not cut roots over 2-inch-in-diameter without approval of Project Manager.

c) Cleanly saw-cut roots between 1-inch and 2-inch-in-diameter where they interfere with work; do not cut roots except as necessary. Roots between 1-inch and 2-inch-in-diameter which must be cut shall be cleanly saw-cut near the edge of trench closest to the tree to prevent roots from being dislodged from soil by equipment.

k. Avoid soil compaction within plant root zones with heavy equipment and vehicles within the project work limits.

1. Do not cut wheels or make sharp turns with wheeled or tracked equipment in root zones.

m. Do not pile excavated soil against tree trunks.

n. Do not mechanically compact soils in undeveloped areas except to meet minimum compaction requirements as approved by the Project Manager.

o. Maintain original soil topography in plant root zones whenever possible.

p. Preserve tree snags where feasible as potential bat or bird habitat.

3. Plant Appraisal:

a. If the Contractor destroys or injures trees and vegetation designated for protection or outside the work limits, the Contractor will be assessed damages prior to final progress payment.

b. Replacement costs for damaged vegetation will be computed according to the method described in the International Society of Arborculture's 1992 Guide for Plant Appraisal. This method is based on the cost of the largest commonly available tree or shrub, with modifications based on species value, condition, and location. A trained arborist or professional plant appraiser from the California region will be hired by the NPS to make the damage appraisal. The arborist's fees will be included in the damage assessment.

c. This damage appraisal process will be triggered by any of the following types of damage to vegetation outside the work limits or unauthorized disturbance of vegetation within the work limits.

1) Removal of any tree or shrub.

2) Pruning or removal of more than 30 percent of a tree or shrub canopy.

3) Removal or fracture of any limb or trunk that is one of the major structural entities of the damaged plant.

4) Removal or fracture of any limb greater than 12 inches in diameter.

5) Bark damage or removal around more than 30 percent of the trunk circumference.

6) Trenching or soil disturbance within the critical root zone that is deeper than 1-foot unless shown on the Drawings.

NATURAL, CULTURAL & PHYSICAL RESOURCES PROTECTION 013550-11

d. A If the damaged vegetation is protected under the Endangered Species Act or other special legislation, additional penalties may be assessed as per consultation with the U.S. Fish & Wildlife Service.

e. Pruning or removal of vegetation shall be supervised by Project Manager. The designated personnel may designate plant species for salvage. When authorized and supervised by the Project Manager, the Contractor is exempted from any penalties that might be assessed due to damage to vegetation.

1) Acceptable disturbance to roots is limited to 15 percent of the area under the drip line being either cut or filled. Any tree with more than 50 percent of its roots disturbed should be removed during construction at the direction of the Project Manager.

2) Wounds occurring from construction activity may be possible entry sites for disease spores. If a tree is accidentally injured during construction, it may need to be removed at the direction of the Project Manager.

f. Trench alignments or other factors may result in variations in which trees are affected. The Contractor shall accommodate these variations at no additional expense to the Government.

g. Minor cuts and damaged areas shall be assessed by the Project Manager.

Repair to the plant will be at the recommendation of the YNP personnel and approval of the Project Manager.

4. Protection from Exotic Plant Species:

a. Measures shall be taken to prevent the introduction of exotic species in the project area and staging areas. All earth moving equipment must enter the Park free of dirt, dust, mud, seeds, or other potential contaminant. Equip-ment exhibiting any dirt or other material attached to frame, tires, wheels, or other parts shall be thoroughly cleaned by the Contractor before entering the Park. All equipment will be directed to the El Portal Maintenance Facility for inspection prior to commencing work. Areas inspected shall include, but not be limited to, tracks, track guard/housings, belly pans/under covers, buckets, rippers, and other attachments. Equipment that does not pass inspection will be turned around to the nearest cleaning facility outside the park. If vehicles are unable to drive to El Portal due to size or load restrictions, vehicles will be inspected at a mutually agreed site by the Project Manager prior to entering the Park. The Contractor shall notify the Construction manager at least two work days (not including weekends) prior to bringing any equipment into the Park. Equipment found to have entered the Park with potential contaminants will be removed from the Park at the direction of the Project Manager at Con-tractor's sole expense.

b. Minimize ground disturbance to the greatest extent possible.

c. The contractor shall get approval in writing from the Project Manager for fill material that must be used in a way or stored in a location not clearly speci-fied in the contract.

d. Fill materials used within the top 12 inches of finished grade are required to be free of exotic and noxious weed species and shall have the source loca-tions approved by the Project t Manager. The Contractor shall submit to the Project Manager a list of proposed sources for imported fill materials requir-ing certification 30 calendar days in advance of importing material. The pres-

NATURAL, CULTURAL & PHYSICAL RESOURCES PROTECTION 0135 50-12

ence of noxious weed species is grounds for rejection of the source. If exotic weed species are found or suspected, the Contractor may be required to strip the top 12 inches of source material and only import sub-surface material and/or sterilize the material, at the Project Manager's discretion. The pres-ence of the following particularly noxious weed species are grounds for rejec-tion of the source: spotted knapweed, yellow star-thistle, perennial pepper-weed, broom species, and other species on the California State List of Noxious Weeds. If spraying is required, the Contractor shall provide a licensed opera-tor to spray according to applicable state regulations. The Contractor shall not spray any herbicides until approved in writing by the Project Manager.

e. Drain and flush all pumps, tanks, live wells, buckets and other containers that might carry water contaminated with exotic plants and animals, such as the zebra mussel, prior to bringing equipment into the park. Thoroughly wash all hauling tanks and equipment using a hard spray from a garden hose. If equipment was used in infested waters, use the following steps to clean the equipment:

1) Wash with hot water (140 F or 40 C) or a high pressure washer (250 pounds per square inch). Remove all aquatic weeds -- they can carry zebra mussels.

2) Disinfect equipment. Recent research shows that disinfection of nets and equipment with benzalkonium chloride at typical treatment rates (10 milligrams per liter for 24 hours, 100 milligrams per liter for 3 hours, or 250 milligrams per liter for 15 minutes) will effectively elimi- nate most exotic animals. Two other commonly used disinfectants, cal- cium hypochlorite and iodine, are ineffective against zebra mussels.

3) Adult zebra mussels can live more than a week out of water in moist, shaded areas. Dry pumps, nets and other equipment used in infested waters in the sun for two to four days after cleaning. If adult mussels are present, dry equipment for two weeks.

5. Wetlands Protection:

a. A The Contractor shall fence construction areas adjacent to aquatic habitats to prohibit the movement of aquatic species into the construction area and to control siltation and disturbance in aquatic habitats.

b. The Contractor shall salvage and reuse wetland soils as fill to the maximum extent possible.

c. The Contractor shall use trench plugs where designated on the drawings in wetland areas to prevent changes to natural flow patterns.

d. During dewatering, intakes shall be completely screened with wire mesh not larger than 5 millimeters to prevent aquatic species from entering the pump system. Water shall be released or pumped downstream at an appropriate rate to maintain downstream flows during construction.

e. Access routes to and through work locations in the meadows and wetlands shall be planked with 11/8" plywood, stabilization mats or other method ap-proved by the Project Manager.
