Proposal for Environmental Services June 21, 2018 167 South Owasso Blvd West, Little Canada, MN 2 SCOPE OF SERVICES The 1,000-gallon heating oil UST is no longer in use and we propose removal of the UST and collection of confirmation soil sampling in accordance with Minnesota Pollution Control Agency (MPCA) requirements. Our scope of services are as follows: • Coordinate with a registered tank removal subcontractor to excavate and remove the UST. • Screen soil using a photoionization detector (PID) equipped with a 10.6 eV lamp to determine if field-detectable contamination is present. We will also document the condition of the UST during removal. • Collect a total of two soil samples (one from under each end of tank) following MPCA Guidance Document 3-01 and submit to a laboratory for chemical analysis of DRO and VOCs following MPCA Guidance Document 4-04. • If the analytical results detect low-level petroleum impacts, we will prepare an excavation report which includes the analytical reports and recommends no further work. If elevated petroleum impacts are detected, we will complete the excavation report recommending additional work as required by the MPCA. We will be available to discuss regulatory reporting obligations and what next steps may be appropriate. • If no contamination is detected, we will complete a letter report which includes the analytical reports and recommends no further work. SCHEDULE Based on current schedules, we anticipate that the UST removal can be scheduled within two weeks. One day of field work will be necessary. We will receive laboratory results approximately two weeks after they are submitted under normal turnaround. Our report will follow after the analytical results are received. Total time to complete the investigation and issue a report is estimated to be about four weeks from authorization. Faster completion (three weeks) may be possible if a RUSH is put on the laboratory testing, which would result in an increase cost for laboratory testing (double laboratory testing costs). The schedule is subject to change due to extreme weather conditions that delay drilling.
