PUBLIC NOTICE
Nebraska Department of Environment and Energy
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 II operating permit to Broken Bow Power Plant (FID #55093) for of continued operation of Broken Bow Power Plant (BBPP) for six (6) stationary reciprocating internal combustion engines (RICE) – two (2) internal combustion, large bore, diesel fuel emergency engines, and four (4) internal combustion, large bore, dual fuel engines for the generation of electricity (Standard Industrial Classification code 4911) located at 145 South 8th Ave., Broken Bow, Custer County, Nebraska. The potential emissions of regulated air pollutants (in tons per year (tpy)) at this facility will be: 1.90 tpy of Particulate Matter (PM), 1.75 tpy of PM ≤ 10 microns (PM10), 1.70 tpy PM ≤ 2.5 microns (PM2.5), 1.55 tpy Sulfur Dioxide, 98.00 tpy Oxides of Nitrogen, 35.53 tpy Carbon Monoxide, 6.13 tpy Volatile Organic Compounds, 1.69 tpy of formaldehyde (largest quantity individual Hazardous Air Pollutant (HAP), 2.44 tpy total HAPs, and 5,010.51 tpy Greenhouse Gases CO2 equivalents (CO2e).
Custer County meets the National Ambient Air Quality Standards (NAAQS) for those pollutants subject to a NAAQS and is expected to continue in that status. Custer 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 a Class II operating permit with specific conditions, based on Title 129, which authorizes limiting NOx emissions to 98 tpy; limiting the kWh generated to 6,456,901 kWh in any 12 consecutive month period; restricting fuel usage to diesel fuel or dual fuel; compliance with federal NESHAP Subpart A and ZZZZ standards, and requiring recordkeeping and reporting.
The proposed permit and supporting materials are available for inspection by the public January 14, 2021 through February 15, 2021 at the office of the NDEE, 245 Fallbrook Boulevard, Lincoln, Nebraska, and electronically at http://deq.ne.gov.
