The Erie County Metropolitan Planning Organization said Thursday it has released an alternative-fuels survey to identify public needs for electric-vehicle charging and other fueling infrastructure across the county. The map-backed survey will remain open for one month and asks residents where new facilities — including EV charging, compressed natural gas (CNG), propane and high-ethanol fueling sites — should be located.

Emily, an MPO staff member, said the survey expands last year’s EV questionnaire and plots existing charging locations on the MPO website. ‘‘This map . . . shows where EV registrations are and all the points where we have existing charging stations for electric vehicles, but as well as things like CNG,’’ Emily said. The survey also asks whether residents need public curbside charging, stations at parks, transit facilities or at commercial sites such as grocery stores.

Staff stressed the county’s survey is being done while federal program guidance and funding availability remain uncertain. ‘‘Originally it was for this heavy community charging program,’’ Emily said. ‘‘But with the new changes in federal administration, it’s unclear what will happen. Maybe we will have those funds, but we might not.’’ Committee members and attendees noted projects already funded through the National Electric Vehicle Infrastructure (NEVI) program and other state allocations are proceeding, but that future rounds of funding are not guaranteed.

Committee discussion addressed who would pay for chargers, whether public funds should subsidize private businesses and where public access charging would best serve residents without home chargers. One attendee pointed out biodiesel is produced locally at a Hero BX facility, but no public retail fueling location exists to buy it, a gap staff said they will record in the survey’s results.

Emily said the MPO will publicize the survey and send results to member jurisdictions. A QR code on the meeting packet was tested successfully during the meeting and staff encouraged committee members to complete the five-minute questionnaire. The survey results will be used to prioritize sites should funding become available; no new county funding was committed during the meeting.

The MPO noted contacts and coordination with PennDOT and transit agencies as part of the NEVI planning and said potential grant funding and site selection would follow federal guidance. The survey and map will remain available on the MPO website for one month from the meeting date.
