OEV |
TPH as Motor Oil 1-Hour Average (Mean) limit is 100 ug/L and reported value was 108 ug/L at EFF-006. |
Sentinel Peak Resources will confer with our contract laboratory EPA Method 8015M and see if the method MDL and PQL can be reduced or if an alternative method is available to provide lower detection and reporting limits. If the source of non-compliance can be more definitively determined, a plan to eliminate or minimize the potential for non-compliance will also be formulated. |

Sentinel Peak Resources will confer with our contract laboratory concerning laboratory blank sample contamination and will make sure that sample bottles are cleanly managed, and the sample port is kept clean while filling bottles. TPH compliance achieved with the subsequent sample set obtained on January 22 also affirms that the treatment system is working effectively. If the source of non-compliance can be more definitively determined, a plan to eliminate or minimize the potential for non-compliance will also be formulated. |
