You Found a WHAT?

The short but exciting saga of the removal of a small underground

storage tank

Pamela A. BoatrightOSRHE, RTC Coordinator

View of UST

Initial Characterization

History Probably Jet Fuel/Aviation Gas Some talk about “oil” disposal

Tank and Fluid Volume Calculation Initial Fluid Sample Testing Results Determine Cost of Fluid Disposal

Tank and Fluid Volume Calculation

Tank Measurements

Top of vent pipe to bottom of tank 86 inches

Top of vent pipe to top of tank 38 inches

86-38 = 48 inches diameter Depth of liquid at initial characterization

18 inches Slight kerosene odor (jet fuel)

Fluid Volume Calculation

Height

Depth

Gal Remaining = Depth Factor x Tot. VolumeRatio = H/D, use table to get Depth Factor (or call

OCC to calculate)

Fluid Volume

18”/48” = ratio of 0.375 Depth Factor of 0.3486910 0.3486910 x 550 = 192 gallons

3.5 barrels

It looked like just oily, dirty water, but test results indicated otherwise

Initial Fluid Sample Results

Flashpoint < 108 °F (140°F)261.21

Total Lead 0.32 mg/L (5 mg/L)TCLP

Benzene 685 µg/L (0.5 mg/L)TCLP

Ethylbenzene 2482 µg/L Toluene 9608 µg/L Xylene 14859 µg/L TOX 28.9 mg/L (halogens)

Cost of Characterization

Flashpoint $10 Total Lead $15 Total Halogens $75 BTEX $50 Other costs - Bailer $1 Mgr, Tech & Mileage $288 TOTAL $450

About liquid disposal.....

More Phone calls You won’t believe the prices!

$1800-$2000 ($10.40/gallon) When they returned my calls, that is… OU contractor (PCI) stated that it could be

profiled as “non-regulated”, but I did not pursue this issue since they would not be pumping the tank anyway (would have been an additional cost).

About liquid disposal.....

When all else fails, call your colleagues! Melanie Stinnett helped save OU a lot of

money.

About that liquid...... Secondary Characterization

Clearwater Environmental, Inc. Additional test showed water with only a slight

film of petroleum liquid Submitted proposal of $1250 for removal of the

tank and its destruction Fluid disposal would be a separate cost

Part 13; Removal and Closure165:25-3-64.1

USTs must be removed by a licensed UST Remover (all UST installers are also licensed removers)

Closure in place is rare, but may be granted under certain circumstances

Any sampling at tank closures must be under the supervision of a licensed Remediation Consultant

UST Certified Consultants, etc.

Assessing Site Closure Samples must be analyzed by an “ODEQ

certified laboratory” List of “wastewater” labs at DEQ, but not

specific for soils If contaminated soils, contaminated

ground water, or free product as a liquid or vapor is discovered, the owner must begin a corrective action in accordance with 165:29.

The Removal Process Find (reasonable) contractors Call OKIE to find buried lines, piping Remove the fluid (just prior to tank removal)

Remove the tank Sample native soil and backfill

Wait for results to refill, if a large hole is dug Close up hole Wait for results Approve final report, paperwork, and

invoice

Consultant Requirements Liability Insurance Workers’ Compensation Insurance Notify OKIE Subcontract for licensed tank remover Subcontract for acceptable waste hauler Schedule with OCC (2-week notice

required) and give OU 48-hours notice of intent to remove

Consultant Requirements

Remove and dispose of tanks and lines/piping to meet OCC rules

Collect and analyze soil samples from tank pit as required by OCC

Backfill tank pit with excavated materials and select material to grade

Prepare and submit UST closure reports to OCC (2 copies for OU)

Contractor Requirement Final Closure Report must include:

Tank Destruction Paperwork Soil Lab Results and Lab QA/QC data sheets Waste material destruction paperwork

Does NOT generally cover: Additional soil samples Removal of dispensers, islands, etc. Soil compaction tests Disposal of contaminated soils, water Damages to private utility lines not identified by

the property owner

OCC Pays

OCC Fund Clearwater applied and was approved for

reimbursement for soil testing (42 cubic yards – backfill and native soil) before work started

OCC agreed that one sample each for backfill and native soil would be sufficient
