Air Quality Division
Notice is given to the public, according to Chapter 14 of Title 129 - Nebraska Air Quality Regulations, that the Department is proposing to issue a Class I operating permit to Northern Natural Gas Company – Palmyra Compressor Station (FID# 37514) for the operation of a natural gas compressor station (Standard Industrial Classification code 4922) located at 1170 North 10 Road, Palmyra, Otoe County. The potential emissions of regulated air pollutants (in tons per year (tpy)) at this facility will be: 337.33 tpy of Particulate Matter (PM), 337.33 tpy of PM ≤ 10 microns (PM10), 337.25 tpy PM ≤ 2.5 microns (PM2.5), 29.05 tpy Sulfur Dioxide, 6,643.80 tpy Oxides of Nitrogen, 3,893.78 tpy Carbon Monoxide, 301.31 tpy Volatile Organic Compounds, 79.26 tpy of Hexane (largest quantity individual Hazardous Air Pollutant (HAP), 118.56 tpy total HAPs, and 327,313 tpy Greenhouse Gases CO2 equivalents (CO2e).
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 significant impact on these standards is expected from this project. No impact is anticipated on habitat for any rare or threatened species.
The NDEE proposes to issue a Class I operating permit with specific conditions, based on Title 129, which authorizes the combustion of natural gas in the compressor engines, turbine, and emergency generator engine; limits the hours of operation of the emergency generator; requires detailed recordkeeping and reporting; allows for the temporary replacement of both compressor engines and the turbine; and requires the source to comply with the New Source Performance Standards (NSPS) in 40 CFR 60 Subparts A, GG, and JJJJ, and National Emissions Standards for Hazardous Air Pollutants (NESHAP) in 40 CFR 63 Subparts A, ZZZZ, YYYY, and DDDDD.
The proposed permit and supporting materials are available for inspection by the public March 16, 2021 through April 19, 2021 at the office of the NDEE, Suite 400, 1200 "N" Street, Lincoln, Nebraska, and electronically at http://deq.ne.gov.
