(REVISE) In the tenth bullet change OAR 952-001-0090(6) to OAR 952-001-0090(7)

00160.20 (d) Build America Buy America Act Requirements – REPLACE this subsection, except for the subsection number and title, with the following:

(ADD) If federal highway funds are involved on the Project, the Contractor shall comply with the Build America Buy America Act and implementing regulations (Infrastructure Investment and Jobs Act (“IIJA”), Pub. L. No. 117-58, which includes the Build America, Buy America Act (“the Act”). Pub. L. No. 117-58, Sections 70901-70941).

The Build America Buy America Act requirements apply to construction materials and manufactured products permanently incorporated in the Project. All construction materials and manufactured products permanently incorporated in the Project must be produced in the United States.

Construction materials include an article, Material, or supply that is or consists primarily of only one of the following, with the standard for the material to be considered “produced in the United States’’:

• Non-ferrous metals - All manufacturing processes, from initial smelting or melting through final shaping, coating, and assembly, occurred in the United States.

• Plastic and polymer-based products (including polyvinylchloride, composite building materials, and polymers used in fiber optic cables) - All manufacturing processes, from initial combination of constituent plastic or polymer-based inputs, or, where applicable, constituent composite materials, until the item is in its final form, occurred in the United States.

• Glass (including optic glass) - All manufacturing processes, from initial

Standard Specifications – Updated 7/2026 Page 3 batching and melting of raw materials through annealing, cooling, and cutting occurred in the Unites States.

• Fiber optic cable (including drop cable) - All manufacturing processes, from the initial ribboning (if applicable), through buffering, fiber stranding and jacketing, occurred in the United States. All manufacturing processes also include the standards for glass and optical fiber, but not for non-ferrous metals, plastic and polymer-based products, or any others.

• Optical fiber - All manufacturing processes, from the initial preform fabrication stage through the completion of the draw, occurred in the United States.

• Lumber - All manufacturing processes, from initial debarking through treatment and planing, occurred in the United States.

• Drywall - All manufacturing processes, from initial blending of mined or synthetic gypsum plaster and additives through cutting and drying of sandwiched panels, occurred in the United States.

• Engineered wood - All manufacturing processes from the initial combination of constituent materials until the wood product is in its final form, occurred in the United States.

The classification of an article, material, or supply as construction material is based on its status at the time it is brought to the work site for incorporation in the Project. In general, the work site is the location of the Project at which the construction materials will be incorporated.

FHWA issued a final rule on January 14, 2025 amending FHWA's Buy America regulation to terminate FHWA's general waiver for manufactured products and establish Buy America requirements for manufactured products with respect to Federal-aid highway projects.https://www.federalregister.gov/documents/2025/01/14/2024- 31350/buy-americarequirements-for-manufactured-products

Manufactured products assembled outside the Project Site are also subject to the Build America Buy America requirements. Manufactured products means articles, materials, or supplies that have been:

o Processed into a specific form and shape; or o Combined with other articles, materials, or supplies to create a product with different properties than the individual articles, materials, or supplies.

For manufactured products, the final assembly of the product shall occur within the

United States for projects obligated on or after October 1, 2025. For projects obligated after October 1, 2026, the cost of the components of the product that are mined, produced or manufactured in the United States shall be more than 55 percent of the total cost of all components of the product.

The USDOT issued a Public Interest Waiver for De Minimis Costs and Small Grants.

The final waiver can be viewed here:

https://www.federalregister.gov/documents/2023/08/16/2023-17602/waiver-of-buy-americarequirements-for-de-minimis-costs-and-small-grants and this waiver applies to Materials covered by the Build America Buy America Act.

The public interest waiver is for manufactured products and construction materials for which:

o The total value of the non-compliant products (foreign or unknown origin) is no more than the lesser of $1,000,000 or 5% of total applicable costs for the project*; or o The total amount of Federal financial assistance applied to the project, Standard Specifications – Updated 7/2026 Page 4 through awards or subawards, is below $500,000.

*The “total value of the non-compliant products” includes construction materials and manufactured products only. The “total applicable costs” includes construction materials, iron and steel, and manufactured products. The value of materials are the actual cost of the materials, not the anticipated cost of materials. Furthermore, this bullet does not apply to iron and steel subject to the requirements of 23 U.S.C. 313. The de minimis threshold in 23 CFR 635.410(b)(4) continues to apply for steel and iron. (See 00160.20(a).)

Strict compliance with the Build America, Buy America domestic preferences is required, except to the extent the above public interest waiver applies. The Contractor shall not incorporate construction materials and manufactured products in excess of this amount into the Project. All foreign origin construction materials and manufactured products incorporated in the Project in excess of the amount indicated above shall be removed and replaced with domestic construction materials at the Contractor's expense.

The Contractor shall provide the Engineer with a Certificate of Materials Origin, on a form furnished by the Engineer, before incorporating any applicable construction materials and manufactured products into the Project. Unless a Certificate of Materials Origin has been provided to the Engineer, the products and Materials shall be considered of foreign origin.

The Contractor shall retain manufacturers' certificates verifying the origin of all applicable construction materials and manufactured products for 3 years after the date of final payment for the Project, and shall furnish copies to the Engineer upon request.

Iron and steel Materials and manufactured products that are predominately iron or steel are subject to 00160.20(a).

The Contractor shall include this provision in all subcontracts.

00170.61 Industrial Accident Protection:

(REPLACE) (a) Workers’ Compensation with

00170.61(a) Workers’ Compensation and Employer’s Liability - The Contractor shall provide workers' compensation and employer’s liability coverage for on-the-job injuries as required by 00170.70(e).

00195.50 Progress Payment and Retained Amounts

(REPLACE) (c) Forms of Retainage with

(c) Forms of Retainage - If the Agency withholds retainage, forms of acceptable retainage are specified below in Subsections (1) through (3). Unless the Contractor requests and the Agency accepts a form of retainage under Subsections (1)(b), (2) or (3), the Agency will use the "Cash Option " in (1)(a) of this Subsection. If the Agency incurs additional costs as a result of the Contractor's election to use a form of retainage other than Cash, Option (1)(a), the Agency may recover such costs from the Contractor by a reduction of the final payment.

(1) Cash Options - Retainage will be deducted from progress payments and held by the Agency using one of the following options until final payment is made

Standard Specifications – Updated 7/2026 Page 5 according to 00195.90, unless otherwise specified in the Contract.

(a) Except as otherwise provided, the Agency will hold the cash retainage withheld in a bank or other financial institution deemed appropriate by the Agency. Amounts retained will be included in the final payment made according to 00195.90, unless otherwise specified in the Contract.

(b) If the Contractor elects, the Agency will deposit the cash retainage withheld in an interest-bearing account, in a bank or other financial institution for the benefit of the Agency, as required by ORS 279C.560(5). Interest earned on the account shall accrue to the Contractor. Amounts retained and interest earned will be included in the final payment made according to 00195.90, unless otherwise specified in the Contract.

(2) Alternate A (Retainage Surety Bond) - The Contractor may submit a Surety bond in lieu of all or a portion of the retainage required under the Contract. The Agency will accept this Surety bond unless the Agency first finds in writing good cause for rejection based on unique project circumstances in accordance with ORS 279C.560(1)(c).

The Surety bond must be in substantially the form specified in ORS 701.435 (4) (Oregon House Bill 4006, 2024), and executed by a Surety bonding company that is authorized to transact Surety business in the State of Oregon and may not be a Surety obligation of an individual. The Surety bond and any proceeds of the Surety bond must be made subject to all claims and liens and in the same manner and priority specified for retainage under ORS 279C.550 to 279C.570 and ORS 279C.600 to 279C.625. Agency will reduce the cash retainage held by an amount equal to the value of the Surety bond and pay the amount of the reduction to Contractor according to ORS 279C.570. Any retainage withheld on Work performed by a Subcontractor will be released to the Contractor according to 00195.50(d).

When the Agency accepts a Surety bond in lieu of retainage from the Contractor, the Contractor shall accept Surety bonds from Subcontractors or Suppliers from which the Contractor has withheld retainage. At any time before final payment a Subcontractor may submit a Surety bond to the Contractor and request that the Contractor submit a Surety bond as described above for the portion of the Contractor’s retainage that pertains to the Subcontractor. The Surety bond the Subcontractor provides to the Contractor must meet the Agency requirements specified in the paragraph above. When a Contractor at a Subcontractor’s request obtains and submits a Surety bond under this subsection, the Contractor may withhold from payments to the Subcontractor an amount equivalent to the portion of the Contractor’s Surety bond premium for which the Subcontractor is responsible in accordance with ORS 279C.560 (Oregon House Bill 4006, 2024).

Within 30 Days after a Subcontractor’s request the Contractor shall provide a Surety bond as described above, and the Agency will accept the Surety bond unless:

• the Agency finds in writing good cause for rejection based on unique project circumstances in accordance with ORS 279C.560;

• a Surety bond is not commercially available;

Standard Specifications – Updated 7/2026 Page 6

• the Subcontractor refuses to pay to the Contractor the Subcontractor’s portion of the Surety bond premium; or

• the Subcontractor refuses to provide the Contractor with a Surety bond that meets the requirements of ORS 279C.560(1)(b).

Notwithstanding 00195.50(d), within 30 Days of receiving a Surety bond from Contractor at a Subcontractor’s or Supplier’s request, Agency will release to the Contractor the amount held as retainage that is equivalent to the amount the Contractor submitted as a Surety bond. Contractor shall, within 30 Days after receiving a Surety bond from a Subcontractor or Supplier, release to the Subcontractor or Supplier the amount the Contractor holds as retainage that is equivalent to the amount of the Surety bond submitted, in accordance with

ORS 279C.560(8).

(3) Alternate B (Bonds, Securities, and Other Instruments) - Contractor may deposit bonds, securities or other instruments with the Agency or in a bank or other financial institution, to be held by Agency instead of cash retainage for the benefit of the Agency, which the Agency will accept unless the Agency first finds in writing good cause for rejection based on unique project circumstances, in accordance with ORS 279C.560(1)(c).

If the Contractor deposits bonds, securities or other instruments, and Agency does not reject the bonds, securities or other instruments as permitted by ORS 279C.560(1)(c), the Agency will reduce the cash retainage by an amount equal to the value of the bonds, securities and other instruments. Interest or earnings on the bonds, securities and other instruments accrue to the Contractor.

Bonds, securities and other instruments deposited instead of cash retainage shall be of a character approved by the Director of the Oregon Department of Administrative Services, including, but not limited to:

• Bills, certificates, notes or bonds of the United States;

• Other obligations of the United States or agencies of the United States;

• Obligations of a corporation wholly owned by the federal government;

• Indebtedness of the Federal National Mortgage Association;

• General obligation bonds of the State of Oregon or a political subdivision of the

State of Oregon;

• Irrevocable letters of credit issued by an insured institution, as defined in ORS

Unsuitable topsoil, or topsoil placed by the Contractor without approval in areas to be planted, may be required to be replaced at no additional cost to the Agency.

Furnish submittals in accordance with 1035.04.

(a) Selected Topsoil - Furnish native topsoil from the required excavations meeting the requirements of 00330.10 or from other Agency-controlled lands. The general limits of topsoil materials will be indicated on the plans. The Agency will make the final determination of the areas where the most suitable materials exist. Furnish topsoil that is the fertile part of a soil profile commonly referred to as the "A" horizon, typically ranging in depth from 3 inches to 12 inches. Do not take material for topsoil from a depth greater than 12 inches below existing ground, unless approved.

Select only sources that are well-drained and, before stripping, have a healthy crop of vegetative growth. Remove and dispose of all heavy grass or other vegetation before taking materials from the source.

(b) Imported Topsoil - No imported topsoil shall be placed until the material and the source have been approved. At the Engineer’s discretion, a reinspection of the source or additional testing may be required when the quality of the imported topsoil changes significantly during placement. Furnish imported topsoil conforming to the following:

(1) Sandy Loam Topsoil – Furnish a consistent and well-blended mix which conforms to the following standards:

Clay 5% - 15% Sand 40% - 60% Silt 35% - 55% Organic Matter 2% - 4% pH Range 5.6 - 6.5

01035.11 Seed - Furnish seed meeting the following requirements:

(a) Label - Deliver all seed in standard, sealed containers. Label each container with the following:

• The kind and variety of each seed of 5 percent or more in a mixture, by weight. Be sure that seed mix labels include the words "mixture" or "mixed seed" when the seed is a mixture

• The country or state where the seed is grown

• The lot number or other lot identification

• The total percentage, by weight, of other crop seed

• The total percentage, by weight, of weed seed

• Statement of "No Noxious (weed) Found"

• For each named seed:

• Percentage of germination

• Percentage of hard (non-living) seed, if more than 1 percent

• Percent of PLS for each kind of seed

Special Provisions – Job #900301 Page 15

• Percent and kind of other crop

• Month and year of seed test

• Net weight of contents

• Name and address of seed labeler or seller

• Origin for each seed (state or foreign country)

• If seed inoculant is used, the claimed date that inoculant effectiveness ends

• For treated seeds (if any):

• Statement that the seeds have been treated

• Name of all chemical used in the treatment

• Description process used in the treatment

• Warning statement for all residual chemicals used

• Net weight of each container

• For seeds listed as native, date and location of collection of source (first generation) seed

• For native seeds specified to be collected for direct use on a project, label containers with the date and location of collection sites for each seed species

(b) Quality - Furnish seed meeting the following requirements:

• The seed and labeling complies with Oregon Seed Law and Federal Seed Act.

• The seed has been tested within 18 months of the planting date.

• The seed is not sprouted, moldy, or showing evidence of having been wet or otherwise damaged.

• The seed is labeled as "Oregon Certified Seed" or the equivalent from another state when identified in the Special Provisions. Information about certified seed is available from County Extension Offices, Oregon State University, and the Oregon Department of Agriculture.

(c) Pure Live Seed - Obtain the amount of seed to apply by using the purity and germination percentages from the label on actual bags of seed to be used on the Project.

To calculate the amount of seed to be applied:

• Obtain the PLS factor - Multiply the seed label germination percentage times the seed label purity percentage.

• Divide the specified PLS rate by the PLS factor.

Example: A PLS seeding rate of 10 pounds per acre is specified. The seed label shows a purity of 80 percent and germination is 90 percent. After converting percentages to decimals,

0.80 x 0.90 equals a factor of 0.72. The specified PLS rate, 10 pounds per acre, divided by the factor of 0.72 equals 13.88. In order to meet a PLS seeding rate of 10 pounds per acre, about 14 pounds of seed needs to be applied per acre. For a seed mix, make this calculation for every seed to obtain the total amount to be applied.

(d) Inspection - Each lot of seed is subject to inspection upon delivery to the Project. Seed that is not labeled or that does not conform to the Specifications will be rejected and shall be replaced at no additional cost to the Agency.

(e) Mixes - Furnish seed mixes that meet the labeling, quality and inspection requirements stated above. Submit all other proposed seed or seed mixes for consideration and receive written approval before seeding work begins. Replace rejected seed before planting.
