Additionally, investigation was performed on the same date on a fuel oil tank that remains in use and is the subject of a separate report. No petroleum release was identified related to that tank. Removed Diesel Tank: The tank was located on the north side of the house where indicated on attached drawing. An inspection of the removed tank identified moderate oxidization and very little pitting. The tank was against the foundation wall. There were no visible holes in the removed tank. The native soil was sand, no groundwater was encountered. The tank reportedly was used as a fuel tank for a backup generator. Field methods included visual and olfactory senses as well as use of an HNU Photoionization Detector with an HNU Systems, Inc. , Model PI-101, portable photoionization detector (PID) , with a 10 .2 Ev lamp in accordance with the MPGA Jar Headspace Analytical Screening Procedure. Soil laboratory sampling followed MPCA' recommended procedures for total hydrocarbon analyses including cold storage until delivered to the laboratory. According to the laboratory, all analyses were performed using EPA or other accepted methodologies. There was a slight petroleum odor in some of the removed soil. Soil vapor samples were taken from the final excavation from the west, north, and east tank excavation sidewalls at 6 feet deep and from the tank bottom at 6 .5 feet deep resulting in vapor levels of 2 . 0, 0 .5, 4 .0, and 8 . 0 parts per million (ppm) SERCO Laboratories 1931 West County Road C2.

Samples may be collected by any individual who has been instructed in proper field sampling procedures. We strongly recommend that water samples be collected by a professional in the environmental field. Hov should samples be collected? 1. Samples should be taken from freshly exposed soil. To avoid entering a confined space, soil samples should be taken from the backhoe bucket. 2. Water samples should be taken immediately after the tank is removed from the excavation and should be free of sediment. 3. All samples should be collected directly into the appropriate sample bottles provided by the laboratory. 4. All sample bottles should be clearly labeled with the facility name, date, time, the analysis parameters requested and sample location. 5. Soil samples should be "grab" samples which are representative of the soil at one location and not "composite" samples. 6. Samples should be promptly sealed and placed on ice for transport to the specified laboratory. 7. The laboratory report should contain the name of the person responsible for collecting and transporting the samples, the name of the facility, the sample location, the date the samples were collected and the date the samples were analyzed. What should the samples be analyzed far? Samples collected for tanks containing petroleum products other than gasoline should be analyzed for total hydrocarbons as fuel oil. Samples collected for tanks containing gasoline should be analyzed for benzene, ethyl benzene, toluene, xylenes, and total hydrocarbons as gasoline. Where can I have the samples analyzed? A list of commercial laboratories is available from the MPCA. The MPCA does not endorse or certify laboratories. What do I do with the sampling results? If any contamination is identified in the samples, it must be reported to the MPCA as a release. If no contamination is found, the laboratory report must be retained for a period of three years after tank closure. However, it would be In your best interest to keep a copy of the analytical report in your permanent records. _ J -3- what if the tank is permanently closed in place? Some USTs may be permanently closed in place if the tank cannot be easily excavated and approval is obtained from both the state fire marshal and the local fire marshal. Measurements for petroleum contamination are still required for these tanks. A minimum of two soil borings should be conducted within the tank basin of each tank, regardless of size. This may require conducting borings inside a building. Angled borings which extend under the tank also are acceptable. All soil borings should extend to the water table or five feet deeper than the base of the tank. One soil sample should be obtained from the bottom of each soil boring. Exceptions to these requirements or alternative investigation methods may be allowed by MPCA staff on a site specific basis. Can I backfill the tank basin or replace the tank before I get the laboratory report for the soil samples? If there is no visible petroleum contamination or petroleum odors below the tank when the tank is excavated, go ahead and backfill the excavation or replace the tank. However, if contamination is identified in the samples, some additional investigation and cleanup including soil borings through or near the previous tank basin may be required. If visible contamination or odors are present beneath the tank, it should be reported immediately to the MPCA as a release. Do I have to report an UST closure? The federal UST rules require that the MPCA be notified 30 days before closure of a tank. Notification of a pending closure may be made by phoning the MPCA at 612/643-3415 or 612/643-3412. In addition, state statute requires that an UST notification form must be submitted within 30 days after closure or replacement of an UST for all tanks covered by the federal UST requirements and for all heating oil USTs with a capacity over 1100 gallons. These forms may be obtained by calling 612/643-3413. who do I call for more information? Call the MPCA Tanks and Spills Section at 612/296-6300. From outside the Twin Cities metropolitan area, call the state switchboard toll-free at 1-800-652-9747, and ask for the MPCA.
