Visually inspect each load and piece of treated wood. Reject for use in or above aquatic environments if visible residues, bleeding of preservative, preservative-saturated sawdust, contaminated soil, or other matter is present.

Use pre-fabrication to the extent feasible. When field fabrication is necessary, all cutting and drilling of treated wood, and field preservative treatment of wood exposed by cutting and drilling, shall occur above the OHW. Use tarps, plastic tubs, or similar devices to contain the bulk of any fabrication debris, and wipe off any excess field preservative.

All treated wood structures, including pilings, shall have design features to avoid or minimize impacts and abrasion by livestock, pedestrians, vehicles, vessels, and floats.

Treated wood may be used to construct a bridge, over-water structure or an in-water structure, with the exception of the work containment system, provided that all surfaces exposed to leaching by precipitation, overtopping waves, or submersion are coated with a water-proof seal or barrier are maintained. Apply and contain coatings and paint-on field treatment to prevent contamination. Surfaces that are not exposed to precipitation or wave attack, such as parts of a timber bridge completely covered by the bridge deck, are exempt from this requirement.

During demolition of treated wood, ensure that no treated wood debris falls into the water. If treated wood debris does fall into the water, remove it immediately.

Store removed treated wood debris in appropriate dry storage areas, at least 150 feet away from the regulated work area.

(13) Temporary Power, Communication and Water Lines - Before installing temporary power, communication, or water lines across streams or bodies of water, submit a proposed plan to the Engineer for approval. Do not begin installation before receiving approval from the

Engineer. Proposed plans for installation of temporary power, communication, and water lines and stream crossings shall utilize the following design methods in the listed order of priority:

1. Aerial lines, including lines hung from existing bridges.

2. Directional drilling, boring and jacking that spans the channel migration zone and any associated wetland.

3. Trenching, which is restricted to intermittent streams and may only be used when the stream is naturally dry. For all sections of trenches below the ordinary high water line, backfill with native material and cap with clean gravel suitable for fish use in the project area.

Align each crossing as perpendicular to the watercourse as possible. For drilled, bored, or jacked crossings, ensure that the line is below the total scour prism. Return any large wood displaced by trenching or plowing as nearly as possible to its original position, or otherwise arranged to restore habitat functions.

(14) Injured Fish Notification - If a dead or injured fish is found in the project area, immediately notify the Agency. If the injured fish is in a location where further injury or stress may take place, attempt to move the fish to a safer location, if one is available, near the capture site while keeping the fish in the water and reducing its stress as much as possible. Do not disturb the fish after it has been moved. If the fish is dead or dies while being captured or moved, save the fish and any tags. The Agency will notify appropriate regulatory agencies about the injured or dead fish and provide additional direction to the Contractor.

00290.51 Protection of Sensitive Cultural Sites - Add the following to the end of this subsection:

There are no known sensitive cultural sites on this Project. However, this is a potentially high probability area for cultural resources. Thus, an Inadvertent Discovery Plan (IDP) has been developed for this project and is included below. Please be sure to keep this IDP at the project site during construction.

Inadvertent Discovery Plan for Cultural Resources

OR42: MP 1.06 & MP 1.43 Culvert ODOT Key Number N/A

Project Description: ODOT is replacing the culvert at MP 1.06 & MP 1.43 on OR42.

The goals of this IDP are to outline appropriate communication and protocol, to minimize construction delays and costs when cultural resources are discovered inadvertently during project construction, and to ensure compliance with local, state, and federal cultural resources laws.

The Inadvertent Discovery Plan (IDP) shall be followed if cultural material, including human remains, are encountered during construction. In addition, please refer to SPECs 290.50 & 290.51.

Protocol for coordination in the event of inadvertent discovery:

In the event of an inadvertent discovery of possible archaeological materials, all work will stop immediately in the vicinity of the find.

The area will be secured and protected.

The ODOT REC, Archaeologist, and lead Inspector will be notified. ODOT Archaeologist or REC will notify the State Historic Preservation Office (SHPO). If possible human remains are encountered, the Oregon State Police, Commission on Indian Services (CIS), SHPO, and Tribes will also be notified.

Oregon State Police: Craig Heuberger 503-508-0779

CIS: Daniel Santos 503-986-1067

SHPO: Hurt Roedel 503-986-0674

No work may resume until ODOT Archaeology staff are on-site and able to assess the situation.

If human remains are encountered, do not disturb them in any way. Do not call 911. Do not speak with the media. Secure the location. Do not take Photos.

The ODOT Archaeologist will consult with SHPO and appropriate Tribal Governments and determine an appropriate course of action.

Additional archaeological excavations may be required. This is handled on a case by case basis by the agency Archaeologist in consultation with SHPO and appropriate Tribes.

When to stop work:

Construction work may uncover previously unidentified Native American or Euro-American artifacts. This may occur for a variety of reasons, but may be associated with access restrictions during project development, or if the area contains impervious surfaces throughout most of the project area which would have prevented standard archaeological site discovery methods.

Work must stop when the following types of artifacts and/or features are encountered (Appendix A):

Native American artifacts may include (but are not limited to):

Flaked stone tools (arrowheads, knives scrapers etc.)

Waste flakes that resulted from the construction of flaked stone tools.

Ground stone tools like mortars and pestles.

Layers (strata) of discolored earth resulting from fire hearths. May be black, red or mottled brown and often contain discolored cracked rocks or dark soil with broken shell

Human remains

Structural remains- wooden beams, post holes, fish weirs

Euro-American artifacts may include (but are not limited to):

Glass (from bottles, vessels, windows etc.)

Ceramic (from dinnerware, vessels etc.)

Metal (nails, drink/food cans, tobacco tins, industrial parts etc.)

Building materials (bricks, shingles etc.)

Building remains (foundations, architectural components etc.)

Old Wooden Posts, pilings, or planks (these may be encountered above or below water)

Even what looks to be old garbage could very well be an important archaeological resource

Remains of ships or sea-going vessels, marine hardware etc.

Old farm equipment may indicate historic resources in the area

When in doubt, call it in!

Proceeding with Construction

Construction can proceed only after the proper archaeological inspections have occurred and environmental clearances are obtained. This requires close coordination with SHPO, FHWA and the Tribes.

After an inadvertent discovery, some areas may be specified for close monitoring or ‘no work zones.’ Any such areas will be identified to the Lead Inspector, Project Manager, and appropriate Contractor personnel.

In coordination with the ODOT Archaeologist, the Lead Inspector will verify these identified areas by engineer’s station if available, mark them on site if appropriate.

The Contractor will follow ODOT Standard Specifications for Construction 290.51 and Special Provisions throughout the duration of the project.
