Airport Improvement Program (AIP)
The AIP is administered by FAA and it's broad objective is to assist in the development of the nationwide system of public-use airports adequate to meet the current projected growth of civil aviation. The AIP provides funding for airport planning and development projects at airports included in the National Plan of Integrated Airport Systems (NPIAS). This plan lists development considered necessary to provide a safe, secure, efficient and integrated airport system meeting the needs of civil aviation, national defense and the U.S. Postal Service.

Airport Phases
Planning and construction for the South Suburban Airport is proposed in two phases: inaugural and ultimate. A brief description of each is provided below.
- Inaugural Airport
The inaugural airport is the first stage of construction and includes an area of approximately 4,000 acres in Will County.
- Ultimate Airport
The ultimate airport refers to the potential future build out of the South Suburban Airport. The ultimate airport could encompass approximately 23,000 acres in eastern Will County, Illinois.

The "airport footprint" is the area that will be impacted by the airport, including the land for airport development as well as surrounding lands that may experience various environmental impacts.

Compatible Land Use
According to FAA the compatibility of existing and planned land uses in the vicinity of an airport is usually related to the noise impacts associated with the operation of an airport. Evaluation consists of assuring that proper zoning or other land use controls are being undertaken, to ensure compatible development near the site.

D
Day-Night Average Sound Level (DNL)
The Day-Night Average Sound Level, or DNL, is a single number measure of community noise exposure over a 24-hour period. DNL is a method for predicting the effects on an average population of the long-term exposure to environmental noises. This method applies a 10 dBA adjustment to nighttime (10 p.m. to 7 a.m.) noises because there is increased sensitivity to noises at night.

E
Environmental Impact Statement (EIS)
Under the National Environmental Policy Act (NEPA) Federal agencies must treat environmental impacts as a primary criterion in the evaluation of a proposed action. Preparation of an Environmental Impact Statement (EIS) serves this purpose, and allows analysis of the environmental impacts of a proposed action, mitigation for those impacts, and the participation of interested parties in the environmental review process.
- Draft Environmental Impact Statement (DEIS)
A Draft Environmental Impact Statement (DEIS) is a "working draft" of the EIS. It is prepared and circulated for Federal, state and local agency and public review, and a public hearing is held. Comments are noted and changes are made accordingly.
- Final Environmental Impact Statement (FEIS)
Once comments on the DEIS have been addressed, a Final Environmental Impact Statement (FEIS) is prepared. This is the final and official copy of the EIS.
- Tier 1 EIS
The Tier 1 EIS for the proposed South Suburban Airport focused on the purpose and need for preserving a site for future potential airport development and provided the environmental analysis for initial airport site approval. The Tier 1 EIS did not deal with actual construction or operation of an airport, but only with the broad issue of approving a site for a potential airport.
Go to Tier 1 EIS Page
- Tier 2 EIS
The Tier 2 EIS for the proposed South Suburban Airport is currently being prepared and will focus on construction of the inaugural airport. This is a more specific issue than general site approval, dealt with in the Tier 1 EIS.

Facility Requirements
Facility requirements refer to the airside and landside facilities needed at an airport to accommodate the projected aeronautical forecasts over a specific period of time.

Forecasts
The Master Plan forecasts are a projection of aeronautical activity expected to occur at an airport in botht the short-and long-term.

G
General Aviation (GA)
General Aviation (GA) is defined as that portion of Civil Aviation that encompasses all facets of aeronautical activity except for those carriers certified by the Department of Transportation to provide commercial passenger and air cargo service. GA activities include things like business flights, student pilot and advanced pilot flight training, aerial application flights (crop dusting), aerial mapping, and air ambulance flights. The types of GA aircraft vary from small, single-engine fixed-wing aircraft to helicopters and multi-engine piston or turbine-powered planes.

Greater Chicago Region
The greater Chicago region includes the northeast Illinois/northwest Indiana metropolitan area. Specifically, the greater Chicago region includes Cook, De Kalb, DuPage, Grundy, Kane, Kankakee, Kendall, Lake, McHenry, and Will Counties in Illinois, Lake and Porter Counties in Indiana, and Kenosha County in Wisconsin. Approximately 9.2 million people resided in this thirteen-county area according to the 2000 U.S. Census, making the greater Chicago region the third largest metropolitan area in the United States.

Noise
Noise impacts are assessed through analysis of DNL, the Day-Night Average Sound Level. The typical measure to analyze long-term noise exposure with DNL is the annual average day, which is calculated from total annual noise activities divided by 365 days. Most airport projects analyze noise impacts through a combination of modeling and observations.

Passenger Facility Charges (PFC)
Passenger Facility Charges (PFC) are funds collected from those individuals flying to or from an airport with an approved PFC application on file with FAA. The enabling federal legislation allowing for the collection of such funds states that these revenues may be used "to finance FAA eligible airport-related projects to be carried out in connection with such airport or any other airport which such agency controls."

R
Record of Decision (ROD)
After the FEIS has been completed and circulated there is a minimum 30-day review period. After this minimum time has elapsed, FAA can issue a Record of Decision (ROD) in the Federal Register, outlining their conclusions about the proposed action. Once the ROD is issued, appropriate and approved action may take place. In the case of the Tier 1 EIS for the proposed South Suburban Airport, the FEIS was issued on April 22, 2002 and the ROD was issued on July 12, 2002. The FAA determined that the Will County site was a technically and environmentally feasible location for a potential, new air carrier aiport to serve the greater Chicago region.
