From the Chicago Tribune:
During construction season, it’s not unusual to find dump trucks lined up at Will County’s nine quarry sites that accept so-called clean construction debris. Dumping into retired or underused quarries has long been a subject of concern. The quarries aren’t lined to protect groundwater, and they aren’t regulated as heavily as landfills that accept garbage.
…Bills sponsored by state Rep. Margo McDermed, R-Mokena, and Emily McAsey, D-Lockport, are sitting in a House subcommittee where they are likely to remain. McDermed says the committee chairman, Rep. Daniel Beiser, D-Alton, believes current regulations of quarries go far enough.
…McDermed says Illinois can’t expect the industry to regulate itself, so groundwater monitoring is crucial: “A system that says we’re going to take the word of the person who runs it that it’s clean construction debris because of some random checks by eyesight, that is not a system,” she says.
