AIPG-TX

The TCEQ discovered and fixed several errors found in the soil TPH calculator (columns E and I of the excel sheets) for the >C₁₂-C₁₆ Aliphatic, >C₁₆ – C₂₁ Aliphatic, and the >C₂₁-C₃₅ Aliphatic carbon ranges. The errors were caused by the incorrect referencing of cells within the PCL calculation equation for the listed aliphatic carbon ranges. Instances of the errors occurred in the ^TotSoil_Comb, ^GWSoil_Ing, ^GWSoil_Class3, and ^AirSoil_Inh-V TPH excel sheets.

The soil TPH calculator has been updated and posted on the TCEQ external webpage: https://www.tceq.texas.gov/remediation/trrp/trrppcls.html. The revised version (V 3.0 – 02/2020) should be used moving forward.
