PART 2 – PRODUCTS (Not Used)

PART 3 - EXECUTION

3.1 PERMANENT DECOMMISSIONING

A. Tank Cleaning

1. Drain and flush all piping into the tank, being careful to avoid spilling.

2. Contractor should plan for the tank to be empty, but tank may contain residual sludge and solids; they will arrange for removal, management, and disposal/recycling of this material. Remove any solids or sludge. Any material which cannot be recycled must be disposed of in accordance with applicable federal and state laws. The Contractor is responsible for determining appropriate disposal options for all tank contents.

3. Carefully dig down to the top of the tank.

4. Remove any Ancillary Equipment, e.g., tank gauge pipe, fill pipe, and other tank fixtures.

5. Cap or remove any non-product Ancillary Equipment, leaving the vent line open until the tank is purged of all flammable or explosive vapors. This is referred to as inerting the tank.

6. Temporarily close off all other openings in the tank so that all vapors can be vented through the vent line during the inerting process.

7. All tanks containing combustible and flammable liquids shall be inerted and rendered gas free, using one of the following methods:

a. Inert the tank with dry ice (1.5 pounds per 100 gallons of tank capacity). The dry ice shall be evenly distributed over the whole area of the tank bottom.

June 2023 Section 02 65 00 – Underground Storage Tank Removal Page 24 of 65

During the inerting process, precautions shall be taken to prevent ignitions throughout the Excavation Zone that might be affected by the vapors.

b. Ventilate the tank with air using an eductor-type air mover. Such a device usually uses compressed air to cause the vapors to be drawn out of the tank.

For this method, leave the drop tube in place to ventilate the bottom of the tank. Discharge the vapors a minimum of 12 feet above the ground surface using an eductor extension.

c. Ventilate the tank with air, using a diffused air blower. The air pressure must not exceed 5 pounds per square inch gauge.

d. Inert the tank with a non-reactive gas, such as carbon dioxide or nitrogen.

Again, the internal gas tank pressure shall not exceed 5 pounds per square inch gauge.

8. Monitor the vapor concentration levels in the tank and in the Excavation Zone using a combustible gas meter that has been maintained and calibrated according to the manufacturer's instructions. Once the meter shows levels below 10% of the lower explosive limit (LEL), the tank is considered inerted and safe for removal.

B. Tank Removal

1. In addition to 3.1(A), complete the following:

2. Plug or cap all holes leaving a 1/8-inch vent hole to prevent differential pressures from building up due to temperature differences.

3. Remove all existing concrete and asphalt paving necessary to allow removal of the tank.

4. Excavate soils around and above tank to allow removal.

5. Complete the excavation and remove the tank. As a safety precaution the tank shall be blocked with wood blocks when staged on the ground to prevent the tank from moving.

6. Remove vent line. Cut at cap at one end at edge of excavation. Cut and cap other end at ground surface. Remove all aboveground vent piping. Buried vent line between edge of excavation and ground surface can be left in ground and abandoned in place.

June 2023 Section 02 65 00 – Underground Storage Tank Removal Page 25 of 65

7. If transported, the tank shall be secured on the truck so that the 1/8-inch vent hole is located on the top of the tank.

8. If groundwater is encountered, work will stop immediately, and the Owner will be notified. In accordance with Oregon law, any identified release from the removed tanks will be reported to the Oregon DEQ Tanks Program.

9. If excavated soil exhibits signs of contamination, stockpile the contaminated soil and debris onto a plastic-lined and bermed area. A layer of plastic sheeting (6 mils or greater) shall be placed beneath the stockpile and a layer shall also be placed over the top of the stockpile upon completion of the excavation phase.

Contractor shall perform a visual inspection and test any excavated soil evidencing apparent contamination. Test methods shall include initial hydrocarbon identification by Northwest Method Total Petroleum Hydrocarbons (NWTPH-HCID), and quantification of total petroleum hydrocarbon (TPH) detections in the gasoline range (NWTPH-Gx) and TPH in the diesel range (NWTPH-Dx), as appropriate. Additional follow-up analyses, as specified in OAR 340-122-0218 and 340-122-0340, and any additional analysis for disposal options, are the responsibility of the Contractor.

10. Remove and dismantle, or have the ends cut off the existing tank and piping. The tank shall be punctured, drilled, or cut appropriately to prevent its future use.

11. Contractor must provide the Owner with written verification that tank, Ancillary

Equipment, and any contents have been disposed of in accordance with state and federal regulations. Vehicles used for the transporting of the above-mentioned items from the site shall comply with all local, state, and federal regulations, and all applicable codes and standards.

12. Contractor shall obtain appropriate dismantling/disposal documentation. The

Contractor shall provide copies of completed waste/recycling manifests of the tank removal, which show the ultimate destination of the tank, its lines, and contents. It shall be rendered unsuitable for future use as an UST by puncturing, cutting, or drilling holes in all sections of the tank.

13. The UST and Ancillary Equipment included in the Work to be excavated and disposed of by the Contractor becomes the property of the Contractor, unless otherwise specified by the Owner to be salvaged.

C. Soil Sampling

June 2023 Section 02 65 00 – Underground Storage Tank Removal Page 26 of 65

1. Two soil samples will be collected, one from below each end of the tank and beneath the waste oil and former gasoline AST piping runs as follows:

a. For piping runs between 5 and 20 feet, a minimum of two soil samples must be collected from the native soils directly beneath the areas where contamination is most likely to be found, unless otherwise approved by

DEQ;

b. For piping runs of more than 20 feet in length, beginning at the floor drain, at least one additional soil sample must be collected at each 20-foot interval.

2. Sampling is to be conducted by the Contractor. Contractor is responsible for costs associated with collecting and analyzing samples as described in this section.

3. The samples will be collected using a backhoe bucket, placed into sterile containers provided by an Oregon-accredited laboratory, labeled, and stored on ice for delivery to the laboratory with chain-of-custody documentation.

4. Soil samples will be submitted to the laboratory under a rush turnaround time of

24-48 hours.

5. Following the removal of the tank and collection of soil samples, the tank pit will be left open, and the excavation secured with fencing and/or covered with steel plates.

6. The Contractor is responsible for collecting soil samples from around the excavation to determine proper compaction requirements.

7. The tank pit will be backfilled per Section 31 23 23 “Fill”, once acceptable environmental soil sample analytical results have been received. Backfill material will consist of native material and imported gravel fill as needed. In wet weather conditions, imported gravel fill is expected to be necessary.

D. Site Restoration

1. Backfill Excavation Zone to the original grades that existed prior to construction.

Stockpiled soil which has been determined by laboratory testing required in the Technical Specifications to be uncontaminated may be used if suitable as structural backfill material. Additional structural fill to bring the excavation to grade shall be clean and free of debris or contamination.

June 2023 Section 02 65 00 – Underground Storage Tank Removal Page 27 of 65

2. Backfilling of the Excavation Zone shall not be performed until the soil sample results are made available and the Owner approves filling. Replace asphalt, concrete sidewalks, concrete curbs, and concrete pavements per the Technical Specifications.

E. Decommissioning Reporting

1. Reporting Suspected Releases

a. An owner and permittee of an UST system must notify DEQ within 24 hours, or another reasonable period allowed by DEQ, and follow the procedures in OAR 340-150-0510.

2. Contractor will follow requirements as specified in OAR 340-150-0168(8). Within 30 days after completing the field work or other period approved by DEQ, the permittee must complete and submit to DEQ an underground storage tank decommissioning checklist and site assessment report (OAR 340-150-0180) signed by the owner, permittee and service provider. A release does not relieve the Service Provider of reporting decommissioning within 30 days.
