Why Worry? Downwind Liability for:
*
-
But We Have a PermitThe Third Circuit recently concluded that obtaining apermit under the Clean Air Act Does NOT Shield a company from liabilityfor damages caused by the plant?The Supreme Court refused to take the case on appeal so the decision stands.Bell v. Cheswick Generating Station, 734 F.3d 188, 190 (3d Cir. 2013)cert. denied sub nom.GenOn Power Midwest, L.P. v. Bell, 134 S. Ct. 2696, 189 L. Ed. 2d 739 (2014)Why is this relevant? It is important because otherwise the company would argue that the permit shielded it. The permit shield allows a company to hide from Regulatory Liability for unknown discharges if it has a permit. So, for example, If I have a permit that has limits for NOx, CO2, SO2, and is quiet on Co, cobalt, there is an assumption that even if I discharge Co I am not in violation of the permit. However under this third circuit ruling, the permit shield only protects you against regulatory enforcement. It does not shield you from liability for harm to people or property.

Radox USDA STUDYCase Study 2:Feather Dryer Air Scrubber
100 K SCFM Packed Bed Air Scrubber
USDA Compared ClO2 to RADOX-23 Fenton Treatment System
Gas chromatography ("GC") and mass spectrometry ("MS") was used to determine destruction efficiency
Results From USDA Study:
Samples from Radox-treated air streams had (1) 42 % higher concentration of carbon dioxide (CO2); (2) 69 % lower concentrations of the highly aldehyde compounds, and (3) 52 % lower total VOC when compared to untreated, or ClO2-treated samples.
The RADOX treatment reduced the total perceived odor intensity by 74 while the ClO2 treatment did not significantly alter the odor intensity.
"The RADOX catalyst was shown to be significantly more effective than chlorine dioxide (ClO2) for reducing the concentration of malodorous VOC and total VOC emitted from poultry rendering.
The concentration of highly malodorous aldehyde compounds, which were responsible for a majority of the poultry rendering odor, were not changed by the ClO2 treatment.Additionally, there was a 5-fold higher concentration of indole in the ClO2 samples when compared to RADOX-treated samples.
