� <br /> � <br /> � <br /> SECTfON 3 — SITE HYDROGEOLOGICAL CHARACTERIZATION <br /> I' The property is relatively flat but does generally slope to the east and south. In this old urban <br /> area surrounding sidewalks and pavement carry storm water to an underground combined <br /> , sanitary and storm sewer system. <br /> Circular#532 published by the Illinois State Geological Survey provides hydro geological <br /> � characteristics to a depth of 50' throughout the State of Illinois. This reference source <br /> indicates the general area containing the subject site consists of a layer of rela�:vely <br /> impermeable glacial till to a depth of at least 50'. There is some indication of scattered <br /> ' sand/gravel seams in the 20' — 50' depth range. While Circular#532 is not intended to <br /> represent reliable characteristics for a specific site, it does indicate that the potential for <br /> widespread contamination of groundwater is relatively low in the area of the subject site. <br /> � A se�rch of Illinois State Geological Survey mine records indicate abandoned coalmines <br /> nearby to the southeast and the south. It appears that the Decatur Coal Company and the <br /> � Macon County Coal Company mine extended to within '/4 to '/2 mile to the southeast of the <br /> subject property. Records indicate mining ceased in 1927. Also, records indicate the <br /> Manufacturers and Consumers Coal Company and the Macon County Coal mine extended to <br /> � within approximately one mile to the south. That mining activity appears to have ceased in <br /> 1948. Nline subsidence can be associated with locations above or near underground mines. <br /> However, mines indicated by the records do not appear near enough to affect the subject <br /> , property. No Significant effects have been apparent in the immediate area of this property. <br /> SECTION 4 — SITE INSPECTION <br /> iGeneral <br /> � On October 10, 2000 and on July 10, 2001, Harry M. Cook, Jr., P.E. of Blank, Wesselink, Cook <br /> & Associates, Inc., conducted a visual inspection of the property. An "Environmental Property <br /> Audit Field ChecklisY' was completed and is attached as Exhibit "C". Photographs of the <br /> � property were taken on October 10, 2000 and are attached as Exhibit "D". <br /> � Asbestos Containinq Material (ACM) Lead and Polychlorinated Biphenyi� (PCB's) <br /> The structures currently on the property are scheduled to be demolished to allow for <br /> � redevelopment of the area. <br /> An asbestos inspection has be�n conducted which identified a variety of ACM throughout the <br /> � existing structures. The City of Decatur has indicated that an IDPH licensed contractor will <br /> complete the required abatement design provlded by an fDPH licensed Designer. An <br /> Asbestos Project Manager will monitor the ap�t,�ment work and submit a final report. <br /> ' <br /> � BWC #380-0101.002 Page 6 7/11/01 <br />
