Add the following:

Design and locate equipment repair shops, stationary refueling sites, or other facilities to minimize the potential and impacts of hazardous material spills on Government land.

Before beginning any work, submit a Hazardous Spill Plan. List actions to be taken in the event of a spill. Incorporate preventive measures to be taken, such as the location of mobile refueling facilities, storage and handling of hazardous materials, and similar information. The hazardous spill plan will describe how the contractor will comply with the following three methods to minimize fuel/oil leakage from construction equipment into the stream channel include the following:

i. All equipment used for instream work will be cleaned of external oil, grease, dirt and mud; and leaks repaired; prior to arriving at the project site. All equipment will be inspected by the Contracting Officer’s Representative before unloading at site. Any leaks or accumulations of grease will be corrected before entering streams or areas that drain directly to streams or wetlands.

ii. Equipment used for in-stream or riparian work (including chainsaws and other hand power tools) will be fueled and serviced in an established staging area (site-

C-4 specifically recommended by CDT). When not in use, vehicles will be stored in the designated staging area. The staging area should be in an area that will not deliver fuel, oil, etc. to streams.

iii. Oil-absorbing floating booms, and other equipment such as pads and absorbent “peanuts” appropriate for the size of the stream, will be available on-site during all phases of construction. For very small streams with few pools or slack water, booms may not be effective. More pads and straw bales to anchor booms may be necessary. Booms will be placed in a location that facilitates an immediate response to potential petroleum leakage.

Immediately notify the CO of all hazardous material spills. Provide a written narrative report form no later than 24 hours after the initial report and include the following:

· Description of the item spilled (including identity, quantity, manifest number, and other identifying information).

· Whether amount spilled is EPA or state reportable, and if so whether it was reported, and to whom. Federal and Idaho state regulations regarding spills will be followed: Any spills resulting in a detectable sheen on water shall be reported to the EPA National Response Center (1-800-424-8802). Any spills over 25 gallons will be reported to the IDEQ (1-800-632-800) (or Nevada equivalent), and cleanup will be initiated within 24 hours of the spill.

· Exact time and location of spill including a description of the area involved.

· Containment procedures.

· Summary of any communications the Contractor had with news media, Federal, state and local regulatory agencies and officials, or Forest Service officials.

· Description of clean-up procedures employed or to be employed at the site including final disposition and disposal location of spill residue.

When available provide copies of all spill related clean up and closure documentation and correspondence from regulatory agencies.

The Contractor is solely responsible for all spills or leaks that occur during the performance of this contract. Clean up spills or leaks to the satisfaction of the CO and in a manner that complies with Federal, state, and local laws and regulations.

Delete the entire subsection and replace with the following:

Prior to the start of construction, submit a written plan that provides permanent and temporary erosion control measures to minimize erosion and sedimentation during and after construction. Do not begin work until the necessary controls for that particular phase of work have been implemented. Do not modify the type, size, or location of any control. An alternate erosion control plan with all necessary permits may be submitted 30 days before intended use.

Incorporate all permanent erosion control features into the project at the earliest practicable time, as outlined in the approved plan.

When erosion control measures are not functioning as intended, immediately take corrective action.

157.03_Forest_4_16_2009

The erosion control plan shall include all necessary measures to protect resources and government improvements. The plan shall include, but is not limited to the following:

1. The construction activities and sequence of implementation relating to specific erosion control measures.

2. The location and type of permanent controls to be implemented during construction.

3. The location and type of temporary controls to be implemented during construction.

4. A detailed dewatering plan to construct the diversion described by Section 157.09. Water shall be conveyed around the construction area via rigid pipe or some other means capable of containing both the flow anticipated during the operating season and higher flows in the event of a storm.

Flow will be diverted with pumps or structures such as cofferdams, constructed of non-erodible material, such as sandbags, bladder bags, or other means that divert water. Diversion dams will not be constructed with material mined from the stream or floodplain.

In perennial channels ( and Blue Springs Creek is a perennial channel) , the reconstructed stream channel will be “pre-washed” into a reach equipped with sediment capture devices such as Sedimat, prior to reintroduction of flow to the stream.

The construction site will be rewatered slowly to prevent loss of surface water downstream as the construction site streambed absorbs water and to minimize a sudden increase in turbidity.

In-channel sediment abatement barriers such as Sedimat will capture sediment that is liberated during rewatering of dewatered channels, barriers will be appropriately cleaned out and removed, and captured sediment will be disposed of so it is not reintroduced into stream channels. Such barriers shall be maintained throughout the related construction and removed only when construction is complete and erosion control is assured.

5. The location of each temporary stockpile site for the excavated material, and location of erosion control measures to prevent sediment from washing off of stockpile.

6. A supply of erosion control materials (e.g. silt fence and straw bales) will be kept on hand to respond to sediment emergencies. Sterile straw or certified “weed free” straw will be used to prevent introduction of noxious weeds.

Add to the third paragraph:

Upon completion of construction at the site, the contractor shall remove all temporary dewatering materials and equipment from Government property. This includes items such as pumps, pipes and hoses and sandbags.

Add the following:

The Contractor shall adhere to the following practices:

a) In order to protect aquatic organisms, install screens on the intake of pumps with opening of 3/32 inch.

b) Construct the Dewatering and Sediment Control according to the Contractor’s approved plan.

c) Maintain the roads and stockpiles of material in a manner that prevents direct entry of sediment into the stream, by either preventing the erosion of sediments or collecting the sediments before it reaches the stream.

d) Construct permanent and temporary control features to intercept sediments. A settling basin will be constructed, or a portable one used, that is able to handle the volume of water anticipated, and that provides filtering capability. Dewatering of the excavation site, (of ground water from the excavation) will be done by pumping water to the settling basin and the basin shall be cleaned out when full of sediments. .

e) Any sanitation facilities established by the Contractor shall be located as designated by the CO.

f) All project operations will cease, except efforts to minimize storm or high flow erosion, under precipitation and high flow conditions that result in uncontrollable erosion in the construction area.

157.13 Maintenance and cleanup.

Delete the third paragraph and insert the following:

Erosion control materials such as hay bales and silt fences will be removed by a Forest Service hydrologist or soil scientist when the sites have revegetated. The Forest Service will perform hydromulching or willow planting.

Deposit chips or ground woody material on embankment slopes or outside the roadway to a loose depth less than 6 inches. Minor amounts of chips or ground woody material may be permitted within the roadway if they are thoroughly mixed with soil and do not form a layer.

(h) Debris Mat. Use tree limbs, tops, cull logs, split stumps, wood chunks, and other debris to form a mat upon which construction equipment is operated. Place stumps upside down and blend stumps into the mat.

(i) Decking Firewood Material. Remove brush from decks. Limb and deck logs that do not meet Utilization Standards according to Subsection 201.04 as directed by the CO. Cut logs to lengths less than 30 feet. Ensure that logs stacks are stable and free of brush and soil.

(j) Removal to designated locations. Remove construction slash to designated locations.

(k) Piling. Pile construction slash in designated areas. Place and construct piles so that if the piles are burned, the burning will not damage remaining trees. Keep piles free of dirt from stumps. Cut unmerchantable logs into lengths of less than 20 feet.

(l) Placing Slash on Embankment Slopes. Place construction slash on completed embankment slopes to reduce soil erosion. Place construction slash as flat as practicable on the completed slope. Do not place slash closer than 2 feet below subgrade. Priority for use of available slash is for: (1) through fills; (2) insides of curves; and (3) ditch relief outlets.

(m) Hydrological Sensitive Placement. Where required use this method in combination with other designated methods to dispose of material to reduce erosion and to aid in re-vegetation:

1. Place windrow segments on contours, wrap in type I geotextile.

2. Place logs as log erosion barriers on contours. Place logs so that 80% of their length is on the ground surface.

3. Scatter slash on bare or disturbed areas within or outside the clearing limits as directed.

4. Scatter chips or ground woody material on bare or disturbed areas within or outside the clearing limits as directed.

Place stumps in swales or on sites to form planting pockets. Place windrow segments on contours, wrap in type I geotextile.
