SECTION 02 65 00
UNDERGROUND STORAGE TANK REMOVAL
08/08
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).
This guide specification includes tailoring options for AFCESA, NAVFAC, NASA
and USACE. Selection or deselection of a tailoring option will include or exclude
that option in the section, but editing the resulting section to fit the project
is still required.
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:

01 35 45.00 10 CHEMICAL DATA QUALITY CONTROL.
3.2.1 Sampling
NOTE: If the contents have been properly characterized or already removed and
disposed, delete the non-applicable portions of the specification.
The designer will detail the sampling requirements (number of samples and analytical
methodology) based on the state/local regulations and EM 1110-1-4006 (i.e. tank
contents, contaminated water, pumpable liquids and sludge, stockpiled soils,
and in situ soils).
If the Government is to perform sampling and analyses, specify what data will
be available from the Government. This will enable the Contractor to ascertain
if additional analysis will be required by the TSD facility and should be reflected
in the bid.
See EM 200-1-3, Requirements for Preparation Sampling and Analysis Plans, for
additional information.
Sample tank [product,] [pumpable liquids,] [tank coatings] [and] [sludge]. If the data is not adequate, additional
sampling and analysis to the extent required by the approved [off-site] [permitted treatment, storage or disposal
(TSD)] facility receiving the material is the responsibility of the [Contractor] [Government]. Meeting all regulatory
requirements, including the preparation of hazardous materials and waste for transportation, is the responsibility
of the Contractor.
3.2.2 Analysis
NOTE: The designer will consult the state/local regulations and EM 1110-1-4006
for assistance in determining the appropriate analytical parameters for tank
contents samples. Analytical protocol will also be based on historical records
of tank usage and/or tank contents testing and defined in Section
01 35 45.00 10 CHEMICAL DATA QUALITY CONTROL. Ensure that the Contractor addresses
the specific laboratory preparation and analytical methods to be employed, especially
variations in fuel related analyses.
[Government will] [Contractor shall] test tank contents for the parameters listed herein. Include [total petroleum
hydrocarbons (TPH)] [benzene, ethylbenzene, toluene and xylene (BETX)] [lead] [_____] in the analysis.
3.2.3 Characterization
NOTE: Regarding "in a special manner", some states require that petroleum contaminated
soils (special wastes) be disposed of in specially designated landfills.
Refer to EM 1110-1-4006 for additional information.
[Prior to removing any of the tank contents, characterize the contents to determine the type of required disposal:
[as a [hazardous] [special] waste] [in a special manner] based on local, state, and Federal disposal regulations.
Characterize [tank product] [tank product, pumpable liquids, and sludge] in accordance with 40 CFR 261 and 40 CFR 279
. Submit the waste contents determination and accompanying test results for each phase present in the tank to
the Contracting Officer.] [The following analyses will be performed by the Government prior to removing the
tank contents: [_____]. The Contractor is responsible for any additional requirements identified by the disposal
facility. Do not remove the tank contents until approval is given by the Contracting Officer.]
3.3 CLEARING, GRUBBING AND REMOVALS
NOTE: If underground storage tank removal is part of a larger project which
contains Section 31 11 00 CLEARING AND GRUBBING, use it instead of this paragraph.
Otherwise edit this paragraph as needed.
[Perform clearing and grubbing in accordance with Section 31 11 00 CLEARING AND GRUBBING.] [Clear areas designated
for clearing and grubbing [as shown on the drawings] [as required and directed by the Contracting Officer] of
all trees, stumps, downed timber, brush, rubbish, roots larger than 75 mm 3 inches in diameter, and matted roots
prior to commencing operations. Saw cut concrete or asphalt pavement at the limits of removal and break, remove
and dispose of the the resulting debris [off Government Property] [at the location shown on the drawings]. Chain
link fence shall be [removed and salvaged for reuse] [disposed of off-site].]
3.4 TOPSOIL
NOTE: If underground storage tank removal is part of a larger project which
contains Section 31 00 00 EARTHWORK, use it for topsoil requirements instead
of this paragraph. Otherwise edit this paragraph as needed.
[Topsoil shall meet the requirements in Section 31 00 00 EARTHWORK.] [Strip and stockpile uncontaminated topsoil
separately for reuse [at the location shown] [at a location approved by the Contracting Officer] if it meets
the requirements of clean fill given in Paragraph BACKFILLING.] [Obtain additional topsoil in excess of that
produced by excavation [off-site] [from designated location onsite].] [Cover with topsoil all areas disturbed
by tank removal operations, other than areas to receive pavement or similar surface under this contract.] [Topsoil
shall be used wherever shown or stated on the drawings.]
3.5 PREPARATIONS FOR EXCAVATION
Before excavating, [drain product piping back to the tank] [remove residual liquids trapped in the product lines]
[and] remove all product from the tank. Purge and vent the tank in accordance with API RP 1604, and as specified
herein.
3.5.1 Removal of Product, Pumpable Liquids, and Sludge
NOTE: See EM 1110-1-4006 for the analytical parameters required for recyclability,
reusability and disposal consistent with characterization of tank contents.
If the Defense Re-utilization and Marketing Office (DRMO) is unwilling to take
the wastes, delete reference to delivery inside the installation. Early in
the design stage coordinate with the DRMO to ensure their capabilities are used
to the maximum benefit of the Government and on approved containers that might
be available or required by the DRMO. The bid documents must have a letter
of waste acceptance attached thereto to be considered a responsive bid. Coordinate
with the state regulatory personnel. Other options are addressed in EM 1110-1-4006.
Petroleum contaminated water disposal is addressed in EM 1110-1-4006.
TSD facilities appropriate to accept the wastes generated by this project may
be identified. If an analysis is available, bid acceptance may be subject to
the bidders having a signed letter of acceptance from a permitted TSD attached
to the bid; otherwise the bid should be declared nonresponsive.
[Contain and store tank product, pumpable liquids, and sludge onsite, prior to disposal. Treat contaminated
water as specified. Analyze and segregate tank product, pumpable liquids, and sludge to recover reusable products
prior to being transported to the [designated location] [treatment, storage and disposal (TSD) facility.]] [Remove
and dispose of tank product, pumpable liquids, and sludge. Use of Government facilities for permanent storage
or disposal of the wastes is prohibited. Temporary storage on Government facilities will be allowed only until
testing is complete, manifests (if necessary) are complete, and transportation is arranged.] The Contractor
is responsible for obtaining all required permits. Usable product shall be the property of the [Government]
[Contractor]. Provide approved containers, vehicles, equipment, labor, signs, labels, placards and manifests
and associated land disposal restriction notices and notifications, necessary for accomplishment of the work,

for accomplishment of the work.[ Sampling and analyses of contaminated water, treated water, the Contractor,
and laboratory quality assurance program shall be in accordance with Section 01 35 45.00 10 CHEMICAL DATA QUALITY
CONTROL.]
3.5.2.2 Treatment
Treat contaminated water [onsite] [offsite] by [oil water separation] [_____] [filtering] [air stripping] [and]
[activated carbon], or other means as approved by the Contracting Officer. If contaminated water is to be treated
onsite, specify the proposed treatment in the Work Plan and submit for approval. Install temporary storage and
treatment equipment [in the general vicinity of the tanks] at a location approved by the Contracting Officer.
Sample and analyze treated effluent and secure approval of results by the Contracting Officer before discharge
to [the sanitary sewer] [the surface] [_____]. Treat and discharge effluent in accordance with the discharge
permit.
3.6 PURGING AND INERTING
NOTE: Coordinate explosive limits with health effects, especially for BTEX
(benzene, toluene, ethylbenzene, xylene) containing mixtures. Coordinate with
EM 1110-1-4006, health and safety specialists or industrial hygienists.
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 1.8 kg per 500 L 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, in accordance with Section 01 35 29.13 HEALTH, SAFETY,
AND EMERGENCY RESPONSE PROCEDURES FOR CONTAMINATED SITES.
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.]
[Contaminated soil materials may be used as backfill for tank and pipe excavations.] [To determine soil contamination
levels, continuously monitor soil materials excavated to remove tanks with an OVA/FID capable of detecting volatile
organic vapors to a minimum of one ppm. Further test contaminated soils with OVA/FID readings of [10] [_____]
ppm or greater for TPH and BTEX as specified herein. Soils with OVA/FID readings less than [10] [_____] ppm
may be used as clean backfill.] [Dispose of contaminated soils in accordance with Federal, State, and local regulations.]
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 0.75 mm 30 mil polyethylene
sheeting. Place excavated soil on the impervious barrier and cover with 0.15 mm 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] [disposed of in the
area designated on the drawings] [disposed of off-site] [_____]. Excavated material that is regulated by the
state as a hazardous waste [which is visibly stained] [for which real time vapor monitoring instrument readings
exceed [_____] for volatile and possibly semi-volatile hydrocarbons depending on the performance criteria for
the field screening method] [and] [which has an obvious petroleum odor] [or as required by the State of [_____]
or implementing agency] is considered contaminated. [Stockpile material if the site is a RCRA-designated CAMU]
[Place in containers such as drums, roll-offs or dumpsters] for sampling in accordance with paragraph Stockpiled
Material Sampling. 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 [0.152] [0.762] [_____] mm [6] [30] [_____] mils thick, covered with a [0.152] [0.254]
[_____] mm [6] [10] [_____] mils sheet of geomembrane [as detailed on the drawings] [as specified]. Place the
geomembrane to prevent the stockpiled soil from coming into contact with surface water run-off.] Locate the
[geomembrane] [container] 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 [container] [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 of [10] [_____] ppm or greater for TPH and for BTEX
in accordance with EPA SW-846 and EPA 600/4-79/020, 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 test for every [77] [_____] cubic meters [100] [_____] cubic yards for TPH, and one
test for every [77] [19] [_____] cubic meters [100] [25] [_____] cubic yards for BTEX and TCLP. Soils that contain
[50] [_____] ppm or more TPH, [10] [_____] ppm or more BTEX or have TCLP reading of [10] [_____] 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 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 (interior and exterior
of the tank)] [from the exterior surface of the tank, cap and abandon in place] [as shown on the drawings] [or]
[as directed by the Contracting Officer]. 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 [non-hazardous] [hazardous]
waste facility.] [not contaminated, leave the tank pad in place.]
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 [adjacent to the tank excavation] [at an approved location] [at the location
shown on the drawings] 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] [immunoassay field kits].
b. If tank is [6] [_____] m [20] [_____] feet or less in length, take [two] [_____] samples. Take each
sample [0.60] [_____] m [2] [_____] feet from each end of the tank and [0.60] [_____] m [2] [_____] feet
below the bottom of the excavation.
c. If the tank is greater than [6] [_____] m [20] [_____] feet, take [three] [_____] samples. Take
two samples [0.60] [_____] m [2] [_____] feet from each end of the tank and [0.60] [_____] m [2] [_____]
feet below the bottom of the excavation. Take a third sample from the middle of the tank area and [0.60]
[_____] m [2] [_____] feet below the bottom of the excavation.
d. Analyze samples for TPH, BTEX, and TCLP. Perform sampling and analysis conforming to standards specified
above for stockpiled soils. Soils that contain [50] [_____] ppm or more TPH, [10] [_____] ppm or more
BTEX, or have TCLP reading of [10] [_____] 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 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. [Stockpile onsite in accordance with paragraph Stockpiles] [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] [State of [_____] inspector] will determine the extent of the contaminated
soil to be removed from each site, not to exceed [_____] [cubic meters cubic yards] [kg tons] per site.
Report any evidence indicating that the amount of contaminated soil may exceed the individual site limit
specified, to the [Installation's Environmental Coordinator] [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 in accordance with
Section 01 35 45.00 10 CHEMICAL DATA QUALITY CONTROL.
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 [7.5] [_____] m [25] [_____] linear feet of product delivery piping, [for every change in direction,]
[and at every mechanical joint] 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 paragraph and include Section 33 65 00 CLEANING
PETROLEUM STORAGE TANKS.
2. For tanks 15,120 liters (4,000 gallons) and smaller, select the second optional
paragraph.
[Provide additional requirements for cleaning and vapor freeing tank as specified in Section 33 65 00 CLEANING
PETROLEUM STORAGE TANKS.]
[Provide clean and vapor free tank in accordance with API RP 1604 and the following:
NOTE: Data for these paragraphs should be obtained from the Commanding Officer
of the individual Naval facility having tanks for cleaning.

NOTE: Contact the fuel department of the nearest Naval Supply Center or Depot
to determine if dirty residual fuel can be accepted by the Government for reclamation.
If not reclaimed by the Government, consider the following: Depending on the
amount of residual fuel remaining in the tank after pump down by the Government
and the degree of fuel emulsification, the designer, in consultation with the
activity, should decide on whether to require fuel/water separation under the
scope of this contract, dispose of the mixture as hazardous waste if tests show
presence of hazardous constituents, or use other options available to the Government.
b. Fuel Removal
All possible fuel will be pumped or otherwise removed from the tank by the Government. Consider remaining
fuel contaminated or waste fuel; [pump into 208 liters 55 gallon drums or other suitable containers for
disposal in accordance with approved procedures meeting local, State, and Federal regulations] [provide
oil/water separators for further recovery of fuels and turn over to the Government for use]. Dispose
of remaining fuel emulsions in accordance with applicable local, State, and Federal regulations. Drums
or tanks used for containerizing waste fuel will be furnished by the [Contractor] [Government]. Oil/water
separator for fuel will be furnished by the [Contractor] [Government].
NOTE: Information on the hazardous waste characteristics of sludge in tanks
should be provided by the activity. If not, sampling and analysis must be conducted
during the 0 to 35 percent design stage to properly define scope and costs.
c. Identification of Tanks With Hazardous Waste Sludge and Residue
The following [tank is] [tanks are] known or suspected to contain hazardous wastes:
Tank No. Product Hazardous Waste, Status, Type, and Basis Known
[or Suspect]
[1] [MOGAS] [Sludge and sandblast residue; ignitibility and lead]]
3.9.1 Exterior
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.
Remove soil from the exterior of the tank, piping, and associated equipment to eliminate soil deposition on roadways
during transportation to a temporary storage area, ensure markings will adhere to the surfaces, and simplify
tank cutting. Use non-sparking tools to remove soil. Recover removed uncontaminated soil and soil not regulated
by the state as a hazardous waste [and use them as backfill in the former tank excavation] [and] [or] [disposed
of onsite]. Remove and containerize soil believed to be contaminated, or if the site is a RCRA designated CAMU,
collect it on 3 layers of [0.152] [0.762] [_____] mm [6] [30] [_____] mil impermeable geomembrane and stockpile
it with other contaminated soil removed from the excavation.
3.9.2 Temporary Storage
NOTE: Add any special state/local regulatory requirements.
If the tank is stored after the tank exterior is cleaned and ancillary equipment is removed, and prior to being
cut into sections, label the tank as directed in API RP 1604, place it on blocks, and temporarily store it [on
a flat area adjacent to the excavation] [at the location indicated on the drawings] [in the area of the existing
tank site]. Prior to cleaning the tank interior, monitor the tank atmosphere for combustible vapors and purge
or inert it if combustible vapors are detected. Provide warning labels as follows:
"TANK HAS CONTAINED LEADED GASOLINE
NOT VAPOR FREE
NOT SUITABLE FOR STORAGE OF FOOD OR LIQUIDS
INTENDED FOR HUMAN OR ANIMAL CONSUMPTION
DATE OF REMOVAL: MONTH/DAY/YEAR"
[Make tank unusable for future use, then transport and dispose of tank [at an EPA approved disposal site in accordance
with applicable local, State, and Federal regulations] [in accordance with Federal, State, and local regulations].]
3.9.3 Interior
NOTE: In lieu of eliminating any sheen, many states require a triple rinse.
Coordinate with the appropriate regulators to ascertain what "clean" is, regarding
tank interiors and to determine cleaning requirements for the piping and ancillary
equipment; cleaning operations are highly dependent upon tank material and contents,
and which state requirements are applicable. Often the state fire inspector's
office has been tasked with Subtitle I program implementation; hence the following
NFPA and API standards may be used to a greater degree than in situations in
which another office of state government has been tasked with enforcing the
UST regulations.
NFPA-30 Flammable and Combustible Liquids Codes
NFPA-327 Standard Procedure for Cleaning or Safeguarding Small Tanks and Containers
NFPA-329 Recommended Practice for Handling Underground Leakage of Flammable
and Combustible Liquids
API Std 2015 Cleaning Petroleum Storage Tanks
If API Std 2015 is used, flooding the tank should not be used in any circumstances.
[Clean tank interior using a high pressure (greater than 3.45 MPa 500 psi), low volume (less than 0.13 L/s 2
gpm) water spray] [or] [Steam clean tank interior until all loose scale and sludge is removed, and contamination,
in the form of a sheen, is no longer visible in the effluent stream]. Also clean the interior surfaces of piping,
to the extent possible, using the same method used for cleaning the tank. Contaminated water generated from
interior cleaning operations (of both piping and tank) shall not exceed the following quantities for each UST
cleaned:
UST VOLUME (LITERS) PERCENT OF UST VOLUME
3,785 or less 5
37,850 or less 5 or 378 L, whichever is less
75,700 or less 1 or 568 L, whichever is less
greater than 75,700 1 or 946 L, whichever is less
UST VOLUME (GALLONS) PERCENT OF UST VOLUME
1,000 or less 5
10,000 or less 5 or 100 gal., whichever is less
20,000 or less 1 or 150 gal., whichever is less
greater than 20,000 1 or 250 gal., whichever is less
[Collect and store onsite] [Discharge to the installation sanitary sewer after passing through an oil water separator]
[Handle in accordance with paragraph Contaminated Water Disposal] all contaminated water resulting from cleaning
operations. Clean so as to eliminate, to the greatest extent possible, the need for personnel to enter the tank.
Use specially designed tank cleaning equipment which allows the tank to be cleaned prior to cutting into sections
without requiring personnel to enter the tank or, if less specialized equipment is used, the tank shall be partially
dissected to overcome confined space entry hazards. Accomplish this work in accordance with Section
01 35 29.13 HEALTH, SAFETY, AND EMERGENCY RESPONSE PROCEDURES FOR CONTAMINATED SITES.
3.10 SOIL EXAMINATION, TESTING, AND ANALYSIS
3.10.1 Tank Excavation Sampling Procedures
NOTE: The designer will detail the confirmation soil sampling requirements
and analytical parameters, including pipe trenches and near pump islands, based
on the state/local regulations, EM 1110-1-4006 and EM 200-1-3.
In most cases, a 72-hour turnaround-time (TAT) is appropriate to avoid excessive
downtime or remobilization of the Contractor; determine if a quicker TAT is
warranted for the off-site analytical.
If the State will have an individual onsite to oversee sampling and/or excavation
operations, the following may be substituted for the first sentence: "After
soil known to be contaminated has been removed, collect and analyze soil samples
as directed by the Contracting Officer in consultation with [_____]."
A backhoe should be used for soil sampling to eliminate the need to have personnel
enter the excavation.
If the regulators do not specify the number of samples required, use a minimum
of 2 samples at the bottom of the tank excavation zone, with one in the center
of the tank excavation and one where the highest instrument reading was obtained
or where contamination is most likely to occur.
If additional samples will likely be required, it may be best to include additional
testing as a separate bid item so a credit can be easily obtained if the additional
tests are not required.
If there is evidence of spillage around the tank or the possibility of horizontal
movement of leaked material, the following requirement can be added: "A sample
shall be obtained from each of the 4 walls of the excavation at [[600] [_____]
mm [2] [_____] foot vertical intervals] [approximately 2/3 of the total depth
of the excavation] and [composited] [tested as individual samples].
After soil known to be contaminated has been removed or after soil excavation is complete, sample the excavation
with procedures, number, location, and methodology [as specified][in accordance with][state regulations] [and]
[Section 01 35 45.00 10 CHEMICAL DATA QUALITY CONTROL].[ Obtain samples from the pits using a backhoe with a
Shelby tube attached to the bucket.]
3.10.2 Stockpiled Material Sampling
NOTE: Detail the sampling requirements and include unique stockpile segregation
procedures required by the implementing agency in the body of the specification.
Analytical testing of stockpiled soils will be based on visual observation,
knowledge of tank contents records and testing of tank contents.
Soil that is a hazardous waste will not be allowed to be stockpiled. Unless
this is a designated corrective action management unit, stockpiling of hazardous
waste will require a permit. Coordinate with the state on Subtitle C tanks.
[Stockpiled contaminated soil shall be sampled and preserved in accordance with the approved Sampling and Analysis
Plan, and Section 01 35 45.00 10 CHEMICAL DATA QUALITY CONTROL.] [Sampling locations, number and specific procedures
are as required by the [State of [_____]] [implementing agency] and the disposal facility.]
3.10.3 Analysis
NOTE: Hydrocarbon tests may vary vastly from state to state. Designer should
consult the latest state requirements for the appropriate hydrocarbon test methods
and coordinate with Section 01 35 45.00 10 CHEMICAL DATA QUALITY CONTROL.
Take into consideration that testing of stockpiled soils and testing of the
excavation pit to confirm "clean closure" may require different testing. Stockpiled
materials testing is performed relative to disposal criteria, confirmation soil
testing from the pit is tested to demonstrate clean closure.
Test soil samples from the excavation and stockpiled material in accordance with the approved Sampling and Analysis
Plan, and Section 01 35 45.00 10 CHEMICAL DATA QUALITY CONTROL for the following parameters: [total petroleum
hydrocarbon (TPH)] [benzene, ethylbenzene, toluene, xylene (BETX)] [toxicity characteristic leaching procedure
(TCLP)] [the following constituents: [_____]]. Provide copies of all test results to the Contracting Officer.
3.11 BACKFILLING
NOTE: Coordinate with the IA regarding the maximum contaminant levels allowable
for clean closure, and if waste from one stockpile can be used as backfill for
another. Coordinate with the user concerning preferences in regard to leaving
excavations open pending lab results, state inspector's evaluations, road closures
and other factors. Lab turnaround time plays a critical role in the duration
of excavations left open and times must be coordinated. If field analysis is
allowed by the state inspector, this would reduce or eliminate turnaround time
concerns.
If the Government or state will analyze samples, revise this paragraph and give
the length of time the Contractor should expect the excavation to be open.
If additional constituents require analyses to meet state/local closure requirements,
include the appropriate limits in this paragraph and include the same limits
in the definition for clean fill.
Add applicable requirements for backfilling the excavation in this section or
revise the reference to the appropriate section of the specifications; see EM
1110-1-4006 for guidance.
a. Backfill the tank area and any other excavations [as soon as possible after tank and contaminated
soil removals have been completed and confirmation samples have been taken] [only after the soil test
results have been approved]. Complete contaminated soil removal after [the bottom of the tank excavation
is determined to have soil contamination levels below the state standards of [100] [_____] ppm TPH] [approval
by the [state inspector] [Contracting Officer]].
b. Dewater the excavation if necessary. Use stockpiled material, subjected to chemical confirmation
testing as backfill, if it is found to [conform to the requirements of clean fill in accordance with
appropriate [state] [local] regulations] [contain less than [100] [_____] ppm of total petroleum hydrocarbons
(TPH)] [contain less than [10] [_____] ppm of BETX] [_____]. Place clean backfill in layers with a maximum
loose thickness of [_____] [200] mm [_____] [8] inches, compacted to [90] [_____] percent maximum density
for cohesive soils and [95] [_____] percent maximum density for cohesionless soils. Perform density
tests using an approved commercial testing laboratory or by facilities furnished by the Contractor.
Attach test results to Contractor's Quality Control Report. Perform a minimum of 1 density test on [each]
[_____] lift. Determine laboratory tests for moisture density relations in accordance with ASTM D 1557
, Method B, C, or D, or ASTM D 6938. A mechanical tamper may be used, provided that the results are
correlated with those obtained by the hand tamper. Determine field in-place density shall be in accordance
with ASTM D 1556, ASTM D 6938, or ASTM D 2167.
3.12 DISPOSAL REQUIREMENTS
3.12.1 Treatment, Disposal, and Recycling
NOTE: List approved facilities in the area of the project.
Many IA's allow contaminated soil treatment onsite and the specification revised
