"Under provisions of the Clean Air Act, which is intended to improve the quality of the air we breathe, EPA is required to set National Ambient Air Quality Standards for six common air pollutants. These commonly found air pollutants (also known as "criteria pollutants") are found all over the United States. They are particle pollution (often referred to as particulate matter), ground-level ozone, carbon monoxide, sulfur oxides, nitrogen oxides, and lead. For each criteria pollutant, there are specific procedures used for measuring ambient concentrations and for calculating long-term (quarterly or annual) and/or short-term (24-hour) exposure levels. The methods and allowable concentrations vary from one pollutant to another, and within NAAQS revisions for each pollutant. These pollutants can harm your health and the environment, and cause property damage. Of the six pollutants, particle pollution and ground-level ozone are the most widespread health threats. EPA calls these pollutants "criteria" air pollutants because it regulates them by developing human health-based and/or environmentally-based criteria (science-based guidelines) for setting permissible levels. The set of limits based on human health is called primary standards. Another set of limits intended to prevent environmental and property damage is called secondary standards. A geographic area that meets or does better than the primary standard is called an attainment area; areas that don't meet the primary standard are called nonattainment areas. "
"States and tribes submit recommendations to the EPA as to whether or not an area is attaining the national ambient air quality standards for a criteria pollutant. The states and tribes base these recommendations on air quality data collected from monitors at locations in urban and rural settings as well as other information characterizing air quality such as modeling. After working with the states and tribes and considering the information from air quality monitors, and/or models, EPA will "designate" an area as attainment or nonattainment for the standard.
If the air quality in a geographic area meets or is cleaner than the national standard, it is called an attainment area (designated “unclassifiable/attainment”); areas that don't meet the national standard are called nonattainment areas. In some cases, EPA is not able to determine an area's status after evaluating the available information. Those areas are designated "unclassifiable."
Once designations take effect, state and local governments must develop implementation plans outlining how areas will attain and maintain the standards by reducing air pollutant emissions."

A meeting was held today in Wilmington to discuss expansion discuss expansion of the landfill.
Waste Management (WM) owns approximately 93 acres that adjoin an existing landfill area, and by utilizing those additional 93 acres, WM will gain approximately 26 more years of time/space for dumping contaminated but non-hazardous waste. The waste, primarily from construction projects, will not come solely from Will County, but also from neighboring counties.
The 93 acres are around the perimeter of an existing landfill area that includes a Resource Conservation and Recovery Act (RCRA) site that contains hazardous waste. There are 37 corrective action wells in the area and 10 of them, all tied to the
RCRA site, show contamination. Other areas of the existing landfill are newer and constructed differently so contamination is
less of a problem. The wells are tested every 6 months and they are tested shallow, never deep. Apparently, it is not possible to test deep and WM dismisses the possibility of contamination in the deep water.
The new 93 acre sites will be lined and the construction will be layered as follows: clay, gravel (?? or a fiber layer), more clay, a
hard plastic liner, and then a fiber layer. There will be access to a well in the center of the “mound” for monitoring. Supposedly the clay in that area is of a superior type that will allow no leaching of contaminates to the area outside the landfill if by chance there is damage to the hard plastic layer. They claim blasting will not have an impact on the liner. In fact, they claim blasting has no impact on the existing 37 wells either but did admit activities such as fracking, if it were taking place in the area, could be problematic.
After the landfill has reached capacity it does not become a wasteland. The county can do reclamation work on it and make it into a recreational area, but the land area will be lost to residential and agricultural uses due to ???? Unfortunately, the recreational area will have some nasty neighbors, including a crude oil storage depot.
