LORDSTOWN — The village’s attorney has asked the Ohio Power Siting Board to consolidate cases before a regulatory agency involving Lordstown and Trumbull Energy Center, a more than $1 billion power plant under construction there.

At the same time, attorney Matthew M. Ries also asked the state to extend a hearing date and testimony submission deadline 60 days to allow the matters to be heard at one hearing, according to documents filed Monday with the siting board.

Lordstown in July filed a complaint with the siting board asking it to suspend a permit granted in October 2017 to the owners of the energy center to build, operate and maintain the plant. The village alleges the facility does not comply with permit conditions over zoning.

The complaint states siting board approval was based on the project site being zoned industrial when much of the site is zoned residential. The company, Pennsylvania-based Trumbull Asset Management, tried to have 34.7 acres rezoned industrial but was unsuccessful when village council in June rejected the request after hearing concerns from residents.

Other allegations in the complaint include a well to access Lordstown’s water system was being drilled without proper approvals, the energy center never provided detailed engineering drawings of the final design to the village, it does not appear to have an environmental consultant on site, the center is violating a wetland buffer and it is engaging in construction outside the hours listed in the certificate.

Also last month, the village objected to a request by the energy center to amend the certificate to add two temporary laydown yards, which are areas on a construction site used to store vehicles, tools and equipment when they are not in use.

The company has until Aug. 22 to respond to Lordstown’s complaint. Meanwhile, a hearing on the other matter is scheduled for Aug. 28 in Columbus.

Siting board staff recommended changing the permit to allow for the laydown yards, plus other design adjustments, but not without conditions.

Ries argues consolidating the matters will save time, resources and avoid duplication of effort.

“Good cause exists to consolidate these cases because (of) the extrinsically intertwined facts, overlapping witnesses and evidence, and common legal issues surrounding the location, construction and operation” of the energy center, Ries’ request states.

Steve Remillard, chief operating officer for Trumbull Asset Management, declined to comment on the complaint when asked Aug. 2, but wrote in an email, “We will continue to operate transparently and cooperate with the appropriate agencies. We will continue to comply with all rules and regulations. And we will continue to move forward with construction.

“We remain fans of Lordstown, of Trumbull County and of the entire Mahoning Valley. We are happy to be investing in this community,” Remillard wrote.

Work at the site has been underway for several months. At peak construction, the site is expected to provide more than 600 jobs, Remillard said previously. When the plant is operational, it will employ about 22 full-time workers.

Trumbull Asset Management is the Mars, Pa.-based company formed by the project’s equity investors — Korea Southern Power Co., Korea Overseas Infrastructure & Urban Development Corp. and Siemens Energy’s Power Development & Investments — after the three acquired the project last year from developer Clean Energy Future of Massachusetts.
