Construction Requirements

157.03 General.

Delete the first two paragraphs and add the following:

Submit a written erosion control plan detailing specific sediment control measures to minimize delivery of soil and turbidity into the streams and to minimize erosion during the construction period. The plan shall be in accordance with the contract specifications, contract permits, Section 107, and this Section. Submit the erosion control plan proposal to the Contracting Officer for approval at least 21 days before ground disturbing operations begin. Contract permits amend the requirements of this Section. Do not modify the type, size, or location of any control or practice without approval. Measures given in the Plans and Supplemental Specifications are minimum requirements.

Erosion control plan reflect special concerns and measures necessary to protect resources and government improvements. It shall include:

(a) The construction activities and sequence of implementation relating to specific erosion control measures.

(b) The location and type of permanent controls to be implemented during construction.

(c) The location and type of temporary controls to be implemented during construction.

(d) For work in stream channels with running water, a detailed dewatering plan.

(e) For work in stream channels without flowing water describe the level of ground and vegetative disturbance and measures to reduce potential sediment delivery.

(f) Describe what monitoring will take place.

The turbidity of the water 150’ feet downstream shall not be visually greater than the turbidity of the water upstream of the project site.

When this turbidity requirement or other erosion control measures are not met, immediately take corrective action. Cease operations that are causing turbidity and pump the stream around the construction site according to this specification and the Plans until the turbidity requirement can be met. When the interpretation of this requirement is in question, measure turbidity using a turbidity meter as approved by the CO, and provide documentation that operations are in compliance with Section 107.01 Laws to be

Observed, Section 107.10 Environmental Protection, and Section 107.11.

Do not begin work until the necessary controls for that particular phase of work have been implemented. Incorporate all erosion control features into the project at the earliest practicable time, as agreed by the CO.

Operate in a manner that will avoid harm to aquatic organisms whenever possible.

Notify the CO of the intention to dewater the stream, at least 72 hours in advance (not including weekends and holidays). Do not re-route a stream until approved by the CO.

Do not release water through a newly constructed simulated streambed until approved by the CO. After approval, release water slowly and incrementally over a period of at least one hour, or as approved by the CO. During this time, treat any water that does not meet the requirements of the turbidity standard stated in this specification.

157.04 Controls and Limitations on Work. Add the following:

When erosion control materials are to be left on site after the project has been completed, construct erosion controls of organic and bio-degradable materials whenever possible.

157.09 Diversions. Add the Following:

Stream diversion, related appurtenances and measures.

(a) Stream Bypass Dam and Pipe. Construct a sandbag dam and bypass pipe as shown on the Plans or as approved by the CO.

(1) Primary Bypass Dam. Construct the Sandbag Dam in a dry condition by first pumping the stream around the dam. Place temporary cofferdams as needed. Remove irregularities from the streambed to form smooth bedding for the bypass dam. Whenever possible, place the dam so that water does not seep from the downstream side of the dam; if seepage occurs, improve the dam by adding sandbags, improving or adding seals, or other means to minimize seepage from the dam. When it is impossible to eliminate seepage, construct a sump and pump clear water to the upstream side of the dam.

(2) Bypass Dam Impermeable Membrane. Place an impermeable membrane within the sandbag dam and entrenched in the streambed as shown on the

Plans or approved by the CO. When approved by the CO, a small amount of granular bentonite may be used along the edges of the membrane to minimize seepage between the membrane and the streambed. Cut a hole in the membrane to fit the bypass pipe and seal the membrane to the

Bypass Pipe or the Bypass Pipe Collar using gaskets, adhesive strips or other approved methods.

(3) Bypass pipe. Place bypass pipe as shown on the Plans or approved by the

CO. Place the upstream invert of the pipe at the lowest point in the stream channel as practical. Install joints and elbows as shown on the Plans and as needed to accommodate the site layout. Use watertight seals meeting the requirements of Section 712.03. Do not place backfill until the pipe joints have be approved by the CO. Allow water to pass through pipe only after a downstream splash apron has been prepared in a manner that will protect the stream from scour and turbidity, and protect fish from harm.

Construct the bypass in a manner that avoids injury to aquatic organisms.

(4) Downstream Dam. When water flows into the work area from downstream, construct a cofferdam as needed to prevent water from entering the work area.

(5) Sandbags. Prior to placing the lower rows of sandbags, remove the larger rocks or other irregularities from the streambed to form a smooth bed. Use only clean sand or coarse concrete aggregate in the sandbags. Loosely fill and tamp the sandbags in place to minimize seepage between, under, and around the bags.

(6) Bypass Pipe Collar. Install and maintain a leak-proof pipe collar as shown on the Plans or approved by the CO.

(b) Pumps. Install pumps as required to re-route stream around construction site and dewater foundations. When failure of a pump would result in movement of sediment or turbidity beyond the work area, provide a back-up pump that is readily available. Use the pumps for installing and removing the gravity bypass pipes and dams, at other times to facilitate construction operations, and during storms to supplement the gravity bypass. Equip the pump with approved fish screens, appropriate suction and discharge hoses, fittings and flow regulation equipment as needed. Insure that the pumps are clean, free of leaks and that the oil used as lubricant in the pump seal systems is food grade mineral oil. Install and operate pumps in a manner that will avoid impingement of small fish against the intake screens.

(1) Pump intakes. Use one of the following methods of screening on all draft hoses:

i. Perforated Plate; screen openings shall not exceed 3/32 or 0.0938-inches

ii. Profile Bar Screen; the narrowest dimension in the screen openings shall not exceed 0.0689-inches in the narrowest direction.

iii. Woven Wire Screen; screen openings shall not exceed 3/32 or

0.0938-inches the narrow direction.

Check intakes frequently and clean as needed with wire brushing, flushing, or any other acceptable method.

(2) Sump Pumps. Supply pumps capable of dewatering the structure foundation. Insure that pumps are clean and free of leaks. Remove sediment and turbidity in the Sump Pump discharge water prior to re-entering the stream.

(c) Sump Water Discharge. Discharge sump water as shown on the Plan or as approved by the CO. Apply one or more methods to remove sediment from sediment-laden water. Apply additional methods as needed to eliminate increase in downstream turbidity. Use the following methods as needed:

(1) Natural Vegetation/Soil Dispersal and Filtration. Discharge sump water onto areas of ground most advantageous for dispersal and filtration of sediment, e.g. flat heavily vegetated soil. When single point discharge does not function adequately, discharge water into a perforated pipe or series of pipes laid approximately level so that the brown water disperses over a wide area.

(2) Silt Bag Filtration. Discharge sump water into one or more Silt Bags.

Use Silt Bags constructed of Mirafi 180N (or approved equal) with sewn seam strengths of 90% efficiency according to ASTM D4632. Construct bag to hold and filter sump water. Place silt bag(s) on level ground having layer of straw one foot thick minimum.

(3) Settling Basin. Discharge sump water into one or more Basins. The

Basins may be pre-manufactured tanks, folding tanks, geotextile or membranes placed over a sandbag or weed-free straw berm, or other similar basins designed to separate sediment from the water.

(4) Suspended Sediment Coagulation Agent. When other methods do not function adequately, add an approved coagulation agent to water prior to discharging the water onto natural vegetation, Silt Bag, or Settling Basin.

Use a flocculation agent such as Chitisan-based Storm-Klear Gel-Floc, or approved equal. Storm-Klear products are manufactured by Vanson

HaloSource, Inc., and distributed by Natural Site Solutions, 16541

Redmond Way 405-C, Redmond, WA 98052, phone: (425) 861-9499.

Use Suspended Sediment Coagulation Agent according to manufacturer’s recommendations.

(d) Sedimats. Place Sedimats across the streambed as shown on the Plans or approved by the CO. The Sedimat is a proprietary product manufactured by

Indian Valley Industries, Inc. and distributed by Columbia Storage Inc., Vancouver Washington, phone: (800) 426-7976. Use Sedimats according to manufacturer’s recommendations.

(d) Simulated Streambed. After placement of the simulated streambed rock materials as shown on the Plans, wash the fines from the surface of the new streambed and remove the sediment using a downstream sump pump. Provide temporary sandbag dam if needed.

157.11 Temporary Turf Establishment
