RHODE ISLAND DIESEL EMISSIONS REDUCTION PROGRAM

The Rhode Island Department of Transportation (RIDOT) is conducting a Program in accordance with the Environmental Protection Agency’s (EPA) National Clean Diesel Campaign

(NCDC) initiative to reduce pollution from diesel engines throughout the country, including vehicles on highways, city streets, construction sites, and ports.

The Program is necessary in order to achieve the pressing public health and environmental goals outlined Chapter 31-47.3 of the Rhode Island General Laws entitled "The Diesel Emissions

Reduction Act". This act shall be known and may be cited as "An Act Concerning Government

Responsibility To Protect Public Health From Diesel Pollution.”, which aims to reduce emissions from diesel engines through an anti-idling program, ultra-low sulfur diesel use requirements, and retrofitting school buses and construction equipment with filters that reduce emissions up to

90%.

STATEMENT OF INTENT TO COMPLY

State Agency: Rhode Island Department of Transportation RIC No.:

Project: County/State: /Rhode Island

Contractor:

The undersigned, on behalf of the above-named Contractor, agrees to comply with Chapter 31-47.3 of the Rhode Island General Laws entitled “The Rhode Island Diesel Emissions Reduction Act”, and associated specifications by having designated on-road and non-road (non-registered) diesel vehicles/equipment used on the project be retrofitted with a designated emissions reduction device/s.

Job Specific RIC No. 2026-CH-034

106.01.1

BUY AMERICA JOB SPECIFICATION (BABA)

Remove Subsection 106.01.1 from the Standard Specifications in its entirety and replace with:

106.01.1 Buy America Job Specification (BABA)

Introduction:

While existing Buy America requirements previously applied to iron, steel, and certain manufactured goods, the Infrastructure Investment and Jobs Act (IIJA) expands requirements to include all manufactured products and construction materials in construction contracts that include Federal Aid funding in the construction phase. Additional information available in 23 CFR 635.410 Buy America and it’s Q&A at FHWA's Buy America Q and A for Federal-aid Program - Buy America - Contract Administration - Construction - Federal Highway Administration (dot.gov) [fhwa.dot.gov]

Purpose:

Provide materials from domestic sources when products are permanently incorporated into the work.

Ensure all manufacturing processes, including applications of coatings, occur in the United States. A coating includes all processes required to apply the coating to a product to protect or enhance the value of the product. The requirements of this JS are not applicable to equipment, tools, and temporary items, including materials left in place at the Contractor’s convenience.

Certifications:

All certifications are submitted by the prime Contractor. When submitting certifications for materials that are subject to the requirements of this specification, the certification shall be on Form provided by the Department.

Determination of Material Category:

• Foreign or Uncertified Products.

Buy America does not apply to minimal use of steel/iron materials provided that the total cost of all foreign source items used in the contract, as delivered to the project site, is less than $2500 or one-tenth-of-one percent of the total contract amount, whichever is greater.

The total value is that shown to be the cost of the steel and iron products as delivered to the project site. Contractor to keep a log of foreign source items to ensure that the minimal use threshold is not exceeded during the life of the contract.

• Manufactured Products

Provide manufactured products produced in the United States.

A manufactured product is acceptable under this provision if:

JS-2

The manufactured product was manufactured in the United States; and The cost of the components of the manufactured product that are mined, produced, or manufactured in the United States is greater than 55 percent of the total cost of all components of the manufactured product.

• Construction Materials

The category of construction materials excludes cement and cementitious materials, aggregates such as stone, sand, or gravel, or aggregate binding agents or additives.

Construction materials are materials that consist primarily of:

− Non-ferrous metals.

− plastic and polymer-based products (including polyvinylchloride, composite building materials, and polymers used in fiber optic cables);

− glass (including optic glass);

− lumber; or − drywall.

Waivers:

The Contractor may submit a waiver request to the department using RIDOT procedures and form provided in the PMP document management folder. The form must reflect a detailed justification for the use of goods, products, or materials mined, produced, or manufactured outside the United States and including copies of all documentation verifying the unavailability of the material or product.

The Department will submit approved waiver requests to FHWA for review. The Contractor shall investigate and respond to any public comments made to the FHWA Office of Program Administration, indicating that a domestic supplier cannot provide the material for which a waiver has been requested.

Final approval of the Buy America Waiver request will be made by the Administrator, Federal Highway Administration. The waiver will be effective the date following publication in the Federal Register.

Contractor fully understands there is no guarantee a waiver request will be approved. Any contract delays caused by this waiver process will be the sole responsibility of the contractor.

The contractor shall be responsible for all cost associated with any of the construction materials that are permanently incorporated into the project that does not meet the requirements of this Special Provision without prior written approval from the Department, up to and including removal and replacement.

The Contractor may submit a waiver request to the department during construction:

1. Determine which type of the three waivers applies.

o Public Interest Waiver: applying the domestic content procurement preference would be inconsistent with the public interest. A waiver in the public interest may be appropriate where the approving federal agency determines that other important policy goals cannot be achieved consistent with the IIJA requirements, and the proposed waiver would not meet the requirements for a nonavailability or unreasonable cost waiver.

JS-3

o Nonavailability Waiver: for types of iron, steel, manufactured products, or construction materials that are not produced in the United States in sufficient and reasonably available quantities or of a satisfactory quality.

o Unreasonable cost waiver: the inclusion of iron, steel, manufactured products, or construction materials produced in the United States will increase the cost of the overall project by more than 25 percent. Provide documentation that no domestic alternatives are available within this cost parameter. Document in the waiver a comparison of the cost of the domestic product to the cost of the foreign product or a comparison of the overall cost of the project with domestic products to the overall cost of the project with foreign-origin products.

2. Contractor shall prepare waiver documentation including waiver form provided by RIDOT;

located in the PMP portal and submit to the Department’s Project Manager with a cc: to the Construction Manager (RE)

3. RIDOT/Project Manager to Submit waiver to Federal Highway Division.

4. Federal Highway Division submits the waiver to the Made in America Office. All waivers have to be submitted by Federal agencies to the Made in America Office. Project specific waivers require a minimum of 15 calendar day public comment period. General applicability waivers are subject to a minimum 30 calendar day public comment period. Federal agencies are responsible for performing due diligence and approving or rejecting waivers.
