Hazardous Materials

Underground Storage Tank Ordinance No. 4332
Attachment "C"

*OXYGENATE COMPOUNDS: TBA (Tertiary Butyl Alcohol), MTBE (Methyl tertiary Butyl Ether), DIPE (Di-isopropyl Ether), ETBE (Ethyl Tertiary Butyl Ether), TAME (Tertiary Amyl Methyl Ether), and Ethanol. Testing for oxygenate constituents may be required for closure of any contaminated site. 

ANALYSIS PROTOCOL -

TETRAETHYL LEAD (TEL) may be analyzed as total lead. However, a confirmation soil sample must be completed from another borehole at the same depth of the original sample or from a groundwater sample from an up gradient well that is not contaminated with hydrocarbons.

CHLORINATED HYDROCARBONS (CL HC) AND BENZENE, TOLUENE, ETHYL BENZENE, AND XYLENE (BTEX) are analyzed in soil by EPA method 8021. EPA method 8260 is used to analyze water.

OIL & GREASE (O & G) may be analyzed by EPA method 418.1. 

NOTES: Fused capillary columns are preferred, as opposed to packed columns. A packed column may be used as a "first cut" with "dirty" samples or once the hydrocarbons have been characterized and proper QA/QC is followed.

For Drinking Water Sources, EPA recommends that the 500 series methods for volatile organics is used, as opposed to the 600 series. The detection limits are and the quality of QA/QC is better with the 500 series.

For all analysis identified on Attachment D, appropriate standards are to be implemented based on the material stored in the tank during the history of its use. Therefore, it is important to consider the different materials that have been stored in the tank and select the analytical methods accordingly.

Other methodologies may be used to complete analytical tests as they become approved by EPA or DHS. Verify proposed methods with this agency, prior to having analytical completed.
