The St. Louis area is currently designated as a moderate 8-hour ozone nonattainment area. The nonattainment area is located on both sides of the Mississippi River, the dividing line between Missouri and Illinois. The Illinois portion consists of Madison, Monroe, St. Clair and Jersey Counties. The Missouri portion of the nonattainment area consists of Franklin, Jefferson, St. Charles and St. Louis Counties and St. Louis City. The department has prepared numerous air quality planning documents to meet state and federal clean air mandates to address ozone pollution in the St. Louis area. In 1997 the ozone National Ambient Air Quality Standards (NAAQS) was reviewed, and EPA recommended that the ozone standard be changed from 0.12 parts per million of ozone measured over one hour to a standard of 0.08 parts per million measured over eight hours, with the average fourth highest concentration over a three-year period determining whether an area is in compliance. The city of Herculaneum is included in this data set because it is designated as a nonattainment area for lead. abandoned mine lands MO DNR Abandoned mine lands MoDNR and OGI iVBORw0KGgoAAAANSUhEUgAAASwAAADICAYAAABS39xVAAAAAXNSR0IB2cksfwAAAAlwSFlzAAAB 2AAAAdgB+lymcgAAA41JREFUeJzt2dtK3FAYgNEtZmY69dS+g6Xv/0a+gkXQGUenRHpApdC7+MFa N4Hsmx8SPnZ2puPxeBwAAdPSAwD8L8ECMgQLyBAsIEOwgAzBAjIEC8gQLCBDsIAMwQIyBAvIECwg Q7CADMECMgQLyBAsIEOwgAzBAjIEC8gQLCBDsIAMwQIyBAvIECwgQ7CADMECMgQLyBAsIEOwgAzB AjIEC8gQLCBDsIAMwQIyBAvIECwgQ7CADMECMgQLyBAsIEOwgAzBAjIEC8gQLCBDsIAMwQIyBAvI ECwgQ7CADMECMgQLyBAsIEOwgAzBAjIEC8gQLCBDsIAMwQIyBAvIECwgQ7CADMECMgQLyBAsIEOw gAzBAjIEC8gQLCBDsIAMwQIyBAvIECwgQ7CADMECMgQLyBAsIEOwgAzBAjIEC8gQLCBDsIAMwQIy BAvIECwgQ7CADMECMgQLyBAsIEOwgAzBAjIEC8gQLCBDsIAMwQIyBAvIECwgQ7CADMECMgQLyBAs IEOwgAzBAjIEC8gQLBb2OB52D+P09HSsptWrlf3jfqxXZ4tNxscjWCzsZHzabMfh6TDuHx7Gbrcb 6/V6fN5+HuvVZunh+GAEi0Xd/rgdl5eXYzqdxuFwGDc3Ny/X6+vr8eXqi6fDK4LFoq4uv47j8TiO Y4zVtBnfrr+PaZrGZmN3xXuCxeKen59fojWH6uzs75nVfr8f6/WnRWfjYxEsFnV/vxur1WpMvw7c 7+7uxtPT07i4uBAr3hEsFrXdbl+uc6TmP4Xn5+d/1n7fg98Ei0XNUZo/Cedd1mw+cD85OXkJlVjx lmCxqLdhms+x4F+8HUCGYAEZggVkCBaQIVhAhmABGYIFZAgWkCFYQIZgARmCBWQIFpAhWECGYAEZ ggVkCBaQIVhAhmABGYIFZAgWkCFYQIZgARmCBWQIFpAhWECGYAEZggVkCBaQIVhAhmABGYIFZAgW kCFYQIZgARmCBWQIFpAhWECGYAEZggVkCBaQIVhAhmABGYIFZAgWkCFYQIZgARmCBWQIFpAhWECG YAEZggVkCBaQIVhAhmABGYIFZAgWkCFYQIZgARmCBWQIFpAhWECGYAEZggVkCBaQIVhAhmABGYIF ZAgWkCFYQIZgARmCBWQIFpAhWECGYAEZggVkCBaQIVhAhmABGYIFZAgWkCFYQIZgARmCBWQIFpAh WECGYAEZggWMip9EbEnSULdjGwAAAABJRU5ErkJggg==
