BISMARCK, N.D. (AP) — The developer of a proposed oil refinery near picturesque Theodore Roosevelt National Park tells North Dakota regulators the company isn't trying to skirt state permitting law.

The state Public Service Commission Tuesday questioned Meridian Energy Group officials on why the company's production capacity for the Davis Refinery is listed at 49,500 barrels per day — just under the 50,000-barrel threshold that triggers a PSC siting review.

Meridian CEO William Prentice said the company plans for a refinery processing 27,500 barrels daily, with the possibility of expansion. He says if expansion happens, the company will come to the PSC for a siting permit.

Commissioners noted public opposition to the refinery because of its proximity to the park. Commissioner Julie Fedorchak unsuccessfully implored Meridian to voluntarily go through the siting process.
