2/28/2014 From: Miller, David [DNR] Sent: Friday, February 28, 2014 7:45 AM To: 'Lorenson, Lou' Subject: RE: Petroleum contaminated soil in Iowa Lou – I had to do some checking, but here is what I found: 108.4(14) Soil, including petroleum-contaminated soil. a. Uncontaminated soil may be used for fill, landscaping, excavation or grading, or other suitable purpose. b. Petroleum-contaminated soils that have been decontaminated to the satisfaction of the department pursuant to 567—Chapter 120 may be used as follows: (1) Fill material at the original excavation site pursuant to 108.6(1). (2) Alternative cover material at a sanitary landfill pursuant to 567—108.8(455B,455D). Miller comment - 100 ppm or less is considered “to the satisfaction of the Department”. 109.11(2)“h” states, “After the contaminant has evaporated and the total hydrocarbon content is less than 100 ppm, the soil may be used as daily cover material or incorporated into the working face. The soil may not be used for capping or lining.” 113.8(1)“b”(10) states, “Petroleum-contaminated soil, unless managed and remediated pursuant to 567—Chapter 120.” This provisions prohibits MSWLFs from disposing of PCS unless it has been remediated to levels in Ch.120. Miller comment – we have granted variances that PCS could be landfilled as is without getting to the 100 ppm. Double check your permit, but ADC seems to be the answer. DAVID MILLER Environmental Specialist Senior From: Lorenson, Lou [mailto:[email protected]] Sent: Thursday, February 27, 2014 10:11 AM To: Miller, David [DNR] Subject: Petroleum contaminated soil in Iowa Good Morning Mr. Miller, Hope this email reaches you before this winter leaves you frozen. I have a question which I hope you can answer for me. Iowa regulations state that the landfill operator should identify/isolate/treat and test petroleum contaminated soils received above 100 ppm until the level of petroleum in the soil is below 100 ppm. I cannot find out if soil with 20 or even 50 ppm is considered petroleum contaminated soil in Iowa and what if anything special we should be doing with soils with less than 100 ppm petroleum. Thanks, Lou Lorenson District Manager Central Disposal Systems DAVID MILLER
