Notice is given to the public, according to Chapter 14 of Title 129 - Nebraska Air Quality Regulations, that the Department is proposing to issue an Acid Rain permit to the Omaha Public Power District (OPPD) – Nebraska City Station (FID# 58343) to include sulfur dioxide (SO2) emission requirements for the operation of boiler Units 1 and 2 located at 5264 L Road, Nebraska City, Otoe County, Nebraska.

Although USEPA has allocated SO2 allowances to the Nebraska City Station, the number of allowances actually held by an affected source in a unit account may differ from the number allocated because they can be bought, sold or traded. This does not necessitate a revision to the unit SO2 allowance allocations identified in this permit.

Otoe County meets the National Ambient Air Quality Standards (NAAQS) for those pollutants subject to a NAAQS and is expected to continue in that status. Otoe County is unclassifiable in regard to the state Total Reduced Sulfur (TRS) standards and no TRS emissions are expected from this project. No impact is anticipated on habitat for any rare or threatened species.

The NDEE proposes to issue an Acid Rain permit with specific conditions, which states standard requirements that apply to the boilers and the compliance option chosen by the Omaha Public Power District (OPPD), which is to hold allowances equal to or greater than the total amount of SO2 emitted in tons. An allowance in the Acid Rain Program is equal to one ton of SO2 emitted. The term of the proposed permit renewal is five years.

The proposed permit and supporting materials are available for inspection by the public October 20, 2020 through November 23, 2020 at the office of the NDEE, Suite 400, 1200 "N" Street, Lincoln, Nebraska, and electronically at Comments received during this period will be considered prior to the final decision. During this period the applicant, or any interested person or group of persons, may request or petition the Director for a public hearing, the request must state the nature of the issues to be raised and all arguments and factual grounds supporting their position. If a public hearing is granted by the Director, the hearing will be advertised by public notice at least 30 days prior to the hearing.
