Summary

Columbia Gas of Ohio staff told Tiffin City Council the Co Street AMRP will replace aging mainlines, use long‑life plastic pipe, and require appointment‑based service‑line work that needs an adult at home; pre‑construction scheduling is imminent and the company will provide exact dates.

Katie Rosa, a public affairs specialist with Columbia Gas of Ohio, told the Tiffin City Council the company is nearing completion of mainline installation on the Noble Street work and is preparing a larger Co Street mainline replacement project that will cover much of the eastern half of the city.

Rosa said crews will energize a recently installed main midweek and that contractor Miller Pipeline will handle both mainline and service‑line work. "We are actually finishing up mainline installation on Monroe between Noble and Hudson and Erie between Noble and Water," she said, adding that the project has proceeded with minimal disruption so far.

The project will replace mid‑century steel pipe with plastic pipeline, which Rosa said is expected to “last well over 100 years,” and will be done using a mix of open‑cut and directional bore techniques depending on underground utility camera inspections. "It's really case by case," she said, describing directional bore as a low‑impact method used when camera work is clear.

Rosa told council that mainline installation must finish before crews schedule service‑line appointments at residences. Service visits are appointment‑based, typically 2 to 4 hours, and require an adult at home because many meters are inside buildings and appliances must be relit. "People over the age of 18 do need to be home for the appointment," Rosa said, noting crews also relight appliances and notify homeowners if an appliance is red‑tagged.

She described temporary restoration practices required by the Ohio EPA (erosion control, coconut netting, straw, gravel) and said final restoration will include topsoil and seeding; most work for this project is in the public right‑of‑way rather than full road reconstruction. Rosa said she will email council exact pre‑construction dates after a scheduling call and expected pre‑construction toward the end of the month with work likely starting mid‑July.

Rosa encouraged residents with questions to contact Columbia Gas directly and thanked city staff for permitting coordination. Nick, the company's local coordinator, also spoke to construction logistics and on‑site identification for contractor staff and vehicles.
