2019 Alternative Fuels Corridor Request for Nominations

    Fixing America's Surface Transportation Act - Designation of Alternative Fuel Corridors

    Request for Nominations, Round 4

    Interface Between Previous Designations and Current Request for Nominations:

    The first three rounds of corridor designations were announced by FHWA in November 2016, March 2018, and April 2019. This fourth round of corridor designations may provide State or local agencies an opportunity to nominate additional corridors, extend currently designated corridors, and/or nominate a different fuel(s) along an already designated corridor.  It is not FHWA's intention to require formal updates on the first three rounds of corridor designations through this current request for nominations.  However, the following guidelines are provided to clarify the interface between previous designations and this current request for nominations:

    1. If a corridor is extended beyond its starting or ending points, a formal designation proposal through this current request for nominations is needed for the extension.
    2. If additional fuel(s) are proposed for a designated corridor on an existing corridor, a formal designation proposal through this current request for nominations is needed for the additional fuel(s).
    3. If the number of stations along a designated corridor changes (i.e. new stations being added or existing stations being closed), which results in the classification of the corridor being changed from corridor-pending to corridor-ready (or vice versa), a formal designation proposal through this current request for nominations is not needed. In this scenario, the length of the designated corridor does not change, only the status of the designation as corridor-ready or corridor-pending between its starting and ending points changes. The FHWA is working with the National Renewable Energy Laboratory (NREL) to identify these situations, and the corridor point of contact will be notified of any change in designation status. However, if the State, or nominating entity, are aware of facilities along a corridor that have been added or are no longer in operation, it is requested that this information be informally conveyed to FHWA and/or NREL.
    4. The initial round of designations in 2016 allowed the use of Level 2 chargers. FHWA encourages that States identify these highway segments which were designated as "corridor-ready" in Round 1 of the Program –(i.e. currently have only Level 2 chargers) and prioritize these corridors for upgrades to DCFCs. 
    5. Although the entire NHS is included in the corridor program, FHWA is limiting the number of US highways/State roads to 1-2 per nomination in Round 4 so the "build-out" of fueling/charging infrastructure is focused on the Interstates across the country and flipping corridor-pending Interstates to corridor-ready. Also, there must be a compelling case made as to why US highways/State roads should be considered for designation.
    6. The previous three rounds of designations allowed a DC Fast Charging station to have either J1772 combo (CCS) or CHAdeMO connectors. As stated in the above Infrastructure Coverage Criteria Table, starting with Round 4, all DC Fast Charging stations should have both J1772 combo (CCS) and CHAdeMO connectors to be eligible for designation. FHWA does not plan to change the status of corridors that included stations with only one connector type, however it is recommended that these stations be prioritized for upgrades to include both.

    FHWA Areas of Interest for Round 4 Nominations:

    After the completion of the first three rounds of designations, FHWA has identified several areas of interest for the fourth round of corridor designations that State or local agencies should consider when planning/preparing their nominations. The following are the FHWA areas of interest:

    • States that have no corridor designations (pending or ready).
    • Nominations from States that have not submitted an application as a lead.
    • States that currently have existing Interstates/highways that are corridor-ready for one or more alternative fuels, but have not submitted a nomination.
    • Since corridors extend beyond State boundaries, nominations that take into consideration the next fueling site over State or international borders2 are encouraged. Similarly, cooperation between neighboring States is highly encouraged.
    • Nominations that will complete the nation's longest and heavily traveled highways for one of more alternative fuels. For example, I-95, I-10, I-80, I-40, I-35, I-65, I-70, I-81, or I-90.
    • FHWA strongly encourages EV nomination submissions from State and local officials who have Interstate highways within their States that have been targeted for investment in the first 30-month cycle by Electrify America in the National Zero Emission Vehicle Investment Plan. See page 22 of the Cycle 1 Plan, and page 48 of the Cycle 2 Plan.
    • Coordination, integration, and inclusion with other DOT programs and regulations such as thedevelopment/update of State Freight Plans and Long-Range Transportation Plans (LRTPs).
