SECTION 02 65 00

UNDERGROUND STORAGE TANK REMOVAL

02/10 NOTE: This guide specification covers the requirements for removal and disposal of underground, nonhardened tanks and piping used to store petroleum products, waste oils or hazardous wastes in accordance with Federal, State, and local regulations.

Edit this guide specification for project specific requirements by adding, deleting, or revising text. For bracketed items, choose applicable items(s) or insert appropriate information.

Remove information and requirements not required in respective project, whether or not brackets are present.

Comments and suggestions on this guide specification are welcome and should be directed to the technical proponent of the specification. A listing of technical proponents, including their organization designation and telephone number, is on the Internet.

Recommended changes to a UFGS should be submitted as a Criteria Change Request (CCR).

PART 1 GENERAL

NOTE: Show the following information on the project drawings:

(1) Overall installation plan which identifies and locates tanks and equipment; borrow, disposal, and stockpile areas; temporary containment areas; special security areas; shoring and special support requirements; and access routes.

(2) Individual as-built site plans of tank locations which identify site features such as buildings, roads, utilities, topography, trees and shrubs, surface condition, etc. If as-built drawings are not available, a site investigation and site plans are required to show the general location of existing tanks and site features. Detail drawings to include dimensions, sections, elevations, slopes and size of excavations and temporary containment areas. Provide, as part of the Tank Closure Report, a detailed map showing exact location of the tank prior to removal.

(3) Limits of pavement removal, fence removal, and the location of ancillary equipment to be removed.

Hardened tanks are deep buried tanks as would be found with some missile facilities. Note this in the contract as they require deeper excavations and possibly substantial demolition of concrete.

Tanks will not be abandoned in place unless a waiver is granted in accordance with state or local requirements, LEE HQ U.S. Air Force for Air Force Projects, and HQUSACE policy dated 31 July 1990, for Formerly Used Defense Sites. Waivers will be obtained prior to advertising the closure project. Exceptions will be granted when requested in writing on a case by case basis. Absence of contamination must still be verified prior to closure and prior to obtaining a waiver.

Incorporate installation, state and local requirements into this specification, including the necessary approval processes, licensing, or having their representative on site during removal operations. In many cases, the state or local jurisdiction has final authority on approval of the Work Plan. While states often enforce petroleum tank removal regulations, counties and cities are sometimes delegated authority.

Petroleum sludge and contaminated media are often considered "special wastes" and are subject to regulations enforced by the State Fire Marshals Office, local agencies, etc. Some states have adopted federal rules for management of petroleum waste.

State requirements usually involve testing, analysis, and a report. The review by the state may require additional testing or other work, and may take several months; therefore, the designer is forewarned to investigate these requirements in advance. Areas most likely to be impacted are waste and tank disposal, tank cleaning, residue and soil sampling and analysis, contaminated soil disposal or remediation, reporting, and requirements for a clean closure.

Petroleum sites which are known to have extensive soil contamination or where groundwater contamination is a possibility, should have a Corrective Action Plan under Subtitle I of RCRA and applicable state and local regulations; refer to EM 1110-1-4006, Removal of Underground Storage Tanks (USTs).

For sites where the tank contained a hazardous waste, remediation should occur under the RCRA Corrective Action requirements of 40 CFR 264, 40 CFR 265, and applicable state requirements.

Coordinate with the customer regarding possible designer's discussions with the regulators, and the existence of unique requirements. Some MACOMS require the Installation Project/Program Manager to either be responsible for all coordination or be included on all contacts with the regulators. For projects not on an active installation discuss requirements with the regulators and omit references to the installation and the Installation Environmental Coordinator.

Include the applicable state and local regulatory references where appropriate in the body of the specification. It is recommended that the specifier refer to DoD "Policy and Guidelines for Acquisitions Involving Environmental Sampling or Testing (November 2007) The following specifications must be used in conjunction with this section:

After the tank and piping contents have been removed, but prior to excavation beyond the top of the tank, disconnect all the piping except the piping needed to purge or inert the tank. Purge flammable and toxic vapors from the tank or make the tank inert in accordance with API RP 1604, with the exception that filling with water is not permitted and, if dry ice is employed, use a minimum of 3 pounds per 100 gallons of tank volume. Continuously monitor the tank atmosphere for combustible vapors if the tank is purged, or continuously monitor for oxygen, if the tank is inerted.

3.7 EXCAVATION

NOTE: Some states may require the use of VOC emission suppression protocols during excavation, stockpiling, and transportation operations for VOC contaminated soil. The designer may need to include requirements for submittals of VOC suppression products (polyethylene sheeting, foam, or liquid VOC suppressants) and use field demonstrations to show there are no interferences from the suppression technology used with field screening devices. Approval from state/local regulators may be required prior to usage of these products and the designer should specify accordingly.

Mark all excavation areas, as well as work near roadways.

3.7.1 Exploratory Trenches

Excavate exploratory trenches as necessary to determine the tank location, limits and the location of ancillary equipment. Upon commencing exploratory excavation, utilize organic vapor analyzer/flame ionization device (OVA/FID) equipment to obtain readings for [total petroleum hydrocarbons (TPH), and benzene, tolulene, ethylbenzene, and xylene (BTX), and toxicity characteristic leaching procedure (TCLP). If BTEX indicates gasoline, then provide TCLP.

3.7.2 Tank Excavation

NOTE: Acceptable levels of contaminations are dependent on regulations applicable to the location where tanks and piping are being removed; therefore, verify acceptable levels.

For some locations, such as a contaminated site scheduled for site remediation, it may be permissible to use contaminated soil materials for backfill in tank and piping excavations. Get approval from local regulating authority before using contaminated soil materials.

If contaminated soil materials are approved for backfill, retain first bracketed sentence and delete the second and third bracketed sentences.

a. Provide Contracting Officer with written documentation, no later than 30 days before work begins, that proper State or local authorities have been notified. Notify the Contracting Officer at least 48 hours prior to start of tank removal work. Stage operations to minimize the time that tank excavation is open and the time that contaminated soil is exposed to the weather. Provide protection measures around the excavation area to prevent water runoff and to contain the soil within the excavation area.

b. Perform excavation around the perimeter of the tank to limit the amount of potentially petroleum contaminated soil that could be mixed with previously uncontaminated soil. Segregate petroleum contaminated soil in separate stockpiles.

c. Maintain an excavation around the tank of sufficient size to allow workers ample room to complete the work, but also protect the workers from sliding or cave-ins. Install sheeting, bracing, or shoring in the absence of adequate side slopes if there is a need for workers to enter the excavated area. Divert surface water to prevent direct entry into the excavation.

d. Dewatering of the excavation may require a discharge permit by the State and shall be limited to allow adequate access to the tank and piping, to assure a safe excavation, and to ensure that compaction and moisture requirements are met during backfilling. Dewatering may result in the production of petroleum contaminated water and/or free product. Recover free product from the groundwater only as part of necessary dewatering.

e. Collect and test water generated by dewatering during excavation required for removal of tanks or piping, surface water collected in open excavation, or water used for washing equipment or existing concrete or bituminous surfaces, in accordance with EPA 530-R-97-007, EPA 600/4-79/020, EPA SW-846 and state or locally required analyses.

3.7.3 Temporary Containment of Excavated Soil

Provide temporary containment area near the excavated area. Cover containment area with 30 mil polyethylene sheeting. Place excavated soil on the impervious barrier and cover with 6 mil polyethylene sheeting. Provide straw bale berm around the outer limits of the containment area and cover with polyethylene sheets. Secure edges of sheets to keep the polyethylene sheeting in place.

3.7.4 Piping Excavation

Perform excavation as necessary to remove tank piping and ancillary equipment in accordance with paragraphs: Shoring, Tank Excavation, and Open Excavations.

3.7.5 Open Excavations

NOTE: The time that tank excavations are left open depends on a variety of factors, a major one being the capability of the Contractor's lab to provide analyses within the specified turnaround time. Since short turnaround time adds cost, carefully evaluate the need for short turnarounds to avoid unnecessary costs.

If the excavation cannot be left open, it should be lined with a geomembrane and backfilled. This will aid excavation if test results reveal further contamination. However, placing a geomembrane in the excavation prior to backfilling may interfere with future in-situ remediation (e.g. soil vapor extraction, bioventing, etc.) and should only be allowed after careful consideration.

Secure open excavations and stockpile areas while awaiting confirmation test results from the soil beneath the tank. Backfill the excavation as soon as possible after tank and contaminated soil removals have been completed and confirmation samples have been taken. Divert surface water around excavations to prevent water from directly entering into the excavation.

3.7.6 Hidden Structures

During excavation activities, if asphalt pavement, concrete slabs, or other hidden structures are encountered, remove and wash with high pressure water cleaning equipment. Remove and dispose of the pavement, concrete, and other structures as specified in Section 02 41 00 DEMOLITION.

3.7.7 Stockpiles

NOTE: Soils characterized or contaminated by a listed hazardous waste and not excluded by 40 CFR 261.4(b)(10) cannot be stockpiled unless the area has been designated by the state RCRA office as a corrective action management unit (CAMU); stockpiling of hazardous waste soil constitutes storage in a waste pile and requires a RCRA permit; placing hazardous waste contaminated soil onto plastic still constitutes a waste pile; therefore, except as stated above, all hazardous waste soils must be placed into containers such as drums, roll-offs or dumpsters.

If analytical tests have not been taken before editing of this specification, historical data may be used to assume whether a tank contained petroleum waste only or hazardous waste, until analytical test results are in and contents are verified. If the historical information indicates that a tank did not contain hazardous waste (as defined by the state), and there is no reason to believe the tank ever contained hazardous waste, the soil may be stockpiled until analytical test results required of the Contractor are received. If at that time the results indicate the presence of hazardous waste, the contaminated soil must be managed according to RCRA: no stockpiles unless they are designated CAMUs. If historical data indicates the presence of hazardous waste, or if there is no historical data, the specification should be edited to assume that the contaminated soil is hazardous and should be containerized.

Uncontaminated excavated soil and petroleum contaminated soil, that is not a state-regulated hazardous waste, shall be stockpiled and used for backfill in the tank excavation prior to using borrow material. Separately stockpile uncontaminated soil from the contaminated soil, a safe distance away from, but adjacent to, the excavation. Place allowable stockpiles of contaminated soil on an impermeable geomembrane a minimum of 3 layers, each 6 mils thick, covered with a 6 mils sheet of geomembrane . Place the geomembrane to prevent the stockpiled soil from coming into contact with surface water run-off. Locate the geomembrane cover to prevent rain or surface water from coming into contact with the contaminated soil, as well as limit the escape of the volatile constituents in the stockpile.

3.7.8 Acceptable Levels of Contamination

NOTE: Acceptable levels of contamination are dependent on regulations applicable to the location where tanks and piping are being removed. Specifier shall verify acceptable levels.

For some locations such as a contaminated site scheduled for site remediation, it may be permissible to use contaminated soil materials for backfill in tank and piping excavations. Specifier shall get approval from local regulating authority before using contaminated soil materials.

If contaminated soil materials are approved for backfill, delete paragraph.

Take further samples and test soils with OVA/FID readings for TPH and for BTEX and for Napthalene in accordance with the permit to remove USTs, and for toxicity characteristic leaching procedure (TCLP) for lead if leaded gasoline was stored in or near the underground tank being removed. For stockpiled soils, provide a minimum of one composite sample as 4:1 for every 50 cubic yards for TPH, BTEX, Naphalene and TCLP. Or provide a discrete sample for every 20 cubic yards. Soils that contain 1 ppm or more TPH, 5 ppb or more BTEX and Napthalene or have TCLP reading of 1 ppm lead or virgin petroleum products are considered contaminated materials. Soils which are less than the above may be used as clean fill. Furnish results to the Solano County inspector who will approve to backfill or not. Furnish results to the Contracting Officer within 24 hours after the results are obtained.

3.8 REMOVAL OF PIPING, ANCILLARY EQUIPMENT, AND TANK

NOTE: Consult the state regulators to determine how the state views tank and ancillary equipment transportation, disposal and salvage rights, and what state requirements for cleaning are applicable. Depending on tank material and contents, permits and manifests and other documentation may be required.

3.8.1 Piping and Ancillary Equipment

Disconnect all piping and ancillary equipment from the tank. Remove the piping completely. Cap all tank ancillary equipment and piping connections, except those connections necessary to inert the tank within the excavation zone. Clean the piping exterior and ancillary equipment to remove all soil and inspect for signs of corrosion and leakage. Ensure no spillage of the piping contents occurs, as specified in the Work Plan, and as required in paragraph SPILLS. If the soil under and around the tank pad is contaminated, remove the tank pad and dispose of offsite at an approved hazardous waste facility.

3.8.2 Tank

Remove the tank from the excavation and clean the exterior to remove all soil and inspect for signs of corrosion, structural damage, or leakage. Use only non-sparking type materials or equipment which comes into contact with the tank, or in the vicinity of the excavation such as shovels, slings and tools. After removal from the excavation, place the tank on a level surface at an approved location and secure it with wood blocks to prevent movement.

3.8.3 Contaminated Soil, Tank and Piping Excavation Examination NOTE: Determine the appropriate field-screening instruments for health and safety monitoring; methods should be based on historical records of tank contents testing and age of release; refer to EM 1110-1-4006 for selection. Consider the use of immunoassay field kits to save time and money. Separate immunoassay field kits sensitive to the light and heavy fuel fractions are available; these kits will not be used as real time health and safety monitoring devices.

Include the Coordinator's Name, Office, and Phone Number.

If contamination is expected, the state may request to be present onsite to oversee contaminated soil excavation and supervise sampling efforts. The designer's or Environmental Coordinator's experience at the site or similar sites may provide a basis for estimating the amount of contaminated soil.

If USACE labs are expected to perform analysis, coordinate with them early on to verify they have the adequate resources to accomplish the work.

a. After the tank has been removed from the ground, examine and test the adjacent and underlying soil for any evidence of leakage. Visually inspect the soil for staining after removal of all obviously contaminated soil, then screen for the presence of volatile and/or semi-volatile contamination using a real time vapor monitoring instrument or immunoassay field kits.

b. If tank is 20 feet or less in length, take two samples. Take each sample 2 feet from each end of the tank and 2 feet below the bottom of the excavation. If groundwater is encountered, follow the instruction from the permit to remove USTs for sampling.

c. If the tank is greater than 20 feet, take three samples. Take two samples 2 feet from each end of the tank and 2 feet below the bottom of the excavation. Take a third sample from the middle of the tank area and 2 feet below the bottom of the excavation. If groundwater is encountered, follow the instruction from the permit to remove USTs for sampling.

d. Analyze samples for TPH, BTEX, Napthalene and TCLP. Perform sampling and analysis conforming to standards specified above for stockpiled soils. Soils that contain 1 ppm or more TPH, 5 ppb or more BTEX and Napthalene, or have TCLP reading of 1 ppm of lead or virgin petroleum products are considered contaminated materials. Soils which are less than the above may be used as clean fill. Furnish results to the Solano County inspector who will approve to backfill or not. Furnish results to the Contracting Officer within 24 hours after the results are obtained. Along with the results furnish a sketch showing underground tank, sampling location, and extent of excavations.

e. Transport offsite for disposal uncontaminated soil or petroleum contaminated soil not regulated by the state as hazardous waste. Stockpile contaminated soil or suspected contaminated soil, or, if the site is a RCRA-designated CAMU, containerized until further disposition.

f. The Contracting Officer will determine the extent of the contaminated soil to be removed from each site per site. Report any evidence indicating that the amount of contaminated soil may exceed the individual site limit specified, to the Contracting Officer the same day it is discovered. If minimal additional excavation is required, the Contracting Officer may allow the Contractor to proceed. If extensive contamination is encountered, sample the excavation and backfill in accordance with paragraph BACKFILLING.

g. After the known contaminated soil is removed, sample and analyze the excavation.

3.8.4 Testing Along Piping

NOTE: Testing requirements are dependent on regulations applicable to the locations where tanks and piping are being removed. Verify number of tests required and required location for tests.

For every 20 linear feet of product delivery piping, take one soil sample and analyze for TPH, BTEX, and TCLP. Conform sampling and analysis of soil materials to EPA standards specified above.

3.9 TANK CLEANING

NOTE: 1. For tanks larger than 15,120 liters (4,000 gallons) or for projects that have tanks, some of which are smaller or larger than 15,120 liters (4,000 gallons), select the first optional…
