Annual summaries

Annual summaries

Air emission inventory summary information is available from data year 1995 to the present in DNR's air permit search tool.

Detailed instructions
  1. Go to the Air Management Program permit search tool.
  2. Enter your search information and then click on the "Search" button. The search results will appear on the bottom of the screen.
  3. Click the "Go" link located to the left of a FID number. You will see the facility information, facility contacts, etc.
  4. Use the slider bar located on the right of the computer screen to scroll to the bottom of the screen. You will see the available emission inventory reports.
    • If a number of emission inventory reports exist, you will see a slider bar located to the right of the Emission Inventory Reports area.

Statewide

Statewide air emissions

The following information relates to statewide air emissions above reporting levels in Table 1 of NR 438.03, Wis. Adm. Code.

Spreadsheets

Facilities were excluded if the total emission was below the NR 438 reporting level.

CO

Wisconsin carbon monoxide (CO) emissions

Health effects

Carbon monoxide (CO), a criteria pollutant, is a colorless, odorless gas that is emitted by both natural processes and human activity. Although CO exists as a trace constituent of the troposphere, much of human CO exposure that results in elevated levels in the blood is due to incomplete fossil fuel combustion. For more information, visit U.S. EPA's Carbon Monoxide [exit DNR].

This information does not include emissions from portable sources (i.e., rock crushers, hot mix asphalt plants).

NOx

Wisconsin nitrogen oxides (NOx) emissions

Health effects

Nitrogen dioxide (NO2) is a brownish, highly reactive gas that is formed through the oxidation of nitric oxide (NO). Nitrogen oxides (NOx), the term used to describe the sum of NO and NO2, play a role in the formation of ozone in the atmosphere through a complex series of reactions with volatile organic compounds. For more information, visit U.S. EPA's Nitrogen Dioxide [exit DNR].

PM

Wisconsin particulate matter (PM) emissions

Health effects

Particulate matter is the generic term for a broad class of chemically and physically diverse substances that exist as discrete particles (liquid droplets or solids) over a wide range of sizes. Particles originate from a variety of anthropogenic (human-made) stationary and mobile sources as well as natural sources.

Many epidemiologic studies have shown significant associations of ambient PM levels with a variety of human health problems. For more information, visit U.S. EPA's Particulate Matter Standards [exit DNR].

PM10

Wisconsin inhalable coarse particulate matter (PM10) emissions

Health effects

Inhalable coarse particulate matter, also known as PM10 or PM10, is formed by crushing, grinding and abrasion of surfaces, which breaks large pieces of material into smaller pieces. The particles are then suspended by the wind or by anthropogenic (human) activity.

Many studies have shown significant associations of ambient PM10 levels with a variety of human health problems. For more information, visit U.S. EPA's Particulate Matter Basics [exit DNR].

ROG

Wisconsin Reactive Organic Gas (ROG) emissions

Health effects

Volatile Organic Compounds (a.k.a. VOCs or Reactive Organic Gases (ROG)) are precursors to the formation of ozone (O3) near ground level. A wide array of health effects has been attributed to short-term (1 to 3 hrs.), prolonged (6 to 8 hrs.) and long-term (months to years) exposures to ozone. For more information, visit U.S. EPA's Health Effects of Ozone Pollution [exit DNR].

SO2

Wisconsin sulfur dioxide (SO2) emissions

Health effects

Sulfur dioxide (SO2) is a rapidly diffusing reactive gas that is quite soluble in water. It is emitted principally from combustion or processing of sulfur containing fossil fuels and ores.

At elevated concentrations, SO2 can adversely affect human health, vegetation and materials. For more information, visit U.S. EPA's Sulfur Dioxide [exit DNR].

Lead

Wisconsin lead emissions

Health effects

Once taken into the body, lead distributes throughout the body in the blood and is accumulated in the bones. Depending on the level of exposure, lead can adversely affect the nervous system, kidney function, immune system, reproductive and developmental systems and the cardiovascular system. Lead exposure also affects the oxygen carrying capacity of the blood. The lead effects most commonly encountered in current populations are neurological effects in children and cardiovascular effects (e.g., high blood pressure and heart disease) in adults. Infants and young children are especially sensitive to even low levels of lead, which may contribute to behavioral problems, learning deficits and lowered IQ. For more information, visit U.S. EPA's Learn about Lead [exit DNR].

GHG

Wisconsin greenhouse gas emissions

The EPA specifies the air emissions that comprise greenhouse gas (GHG) emissions [exit DNR]. Of the 17 EPA pollutants, Table 1 of NR 438, Wis. Adm. Code [PDF exit DNR], lists four with GHG emissions: carbon dioxide, nitrous oxide, 1,1,1,2-tetrafluoroethane and 1,1-Difluoroethane. Of those four compounds, Wisconsin companies have reported only carbon dioxide and nitrous oxide above NR 438 reporting levels.
