GSA Order: Regulated Substances Storage Tank Management

PBS 1095.2A
Office of Facilities Management, Risk Management Division
OFM-RiskManagementDivision@GSA.gov

Purpose:
To revise GSA’s policy for managing Fuel Storage Tanks and establish GSA’s policy for
managing regulated substance storage tanks.

Background:
Federal, state, and local laws establish standards for the management of storage
tanks (aboveground [ASTs] or underground [USTs]) used or previously used to store
regulated substances, including petroleum. Tanks used to store petroleum are hereafter
referred to as fuel storage tanks (FSTs). Tanks used to store other regulated substances
are referred to as hazardous substance storage tanks (HSTs). Collectively, these tanks
are referred to as regulated substance tanks (RSTs). Owners and operators must
install, operate, and maintain all storage tanks that contain regulated substances in a
manner that prevents or reduces the potential for release of their contents into the
environment. Various laws further mandate requirements for training, emergency
planning, release reporting, and closure procedures.

Per 33 U.S.C. 1323 of the Clean Water Act (CWA), and 42 U.S.C. 6991f of the
Resource Conservation and Recovery Act (RCRA), federal facilities must comply with
Federal, state and local requirements. In addition, consistent with the specific language
in each statute, Federal agencies may be subject to civil penalties for non-compliance.
Consult with the Office of the General Counsel to determine applicability. States are the
primary authority for implementing AST programs. They may also be granted the
primary authority to implement the UST program within their boundaries. The governing
standards of authorized state programs must be no less stringent than Federal laws. In
states that have not been delegated authority, UST systems must comply with the
Federal minimum standards.

One of the greatest risks associated with regulated substances storage is the potential
for releases that can contaminate surface water, groundwater and soil. Releases can
also pose other risks to the environment, human health and safety, as well as the
potential for fire, explosions, property damage, and financial liability.

Applicability:
This order and the companion desk guide apply to Federally owned facilities under the
jurisdiction, custody, and control of the GSA. Limited aspects of this order apply to
facilities operating under a GSA delegation of operation and maintenance authority and
space leased by GSA, as dictated by the provisions of the delegation or lease. This
order is not applicable to RSTs associated with property reported excess for disposal
through the PBS Office of Real Property Disposition.

This order applies to all GSA employees and contractors as they perform their duties.
The following are exceptions:

1.​ The Office of Inspector General (OIG), given its independence under the
Inspector General Reform Act of 2008 (5 U.S.C. §§ 401-424).
2.​ The Civilian Board of Contract Appeals, due to its independent authorities.

Cancellation:
This Order supersedes GSA Order PBS 1095.2, Fuel Storage Tank Management.
Summary of Changes:
1.​ Broadened the scope of the existing policy to include regulated substance
storage tanks and changed the title of the Order to align with the expanded
scope.
2.​ Established the National Computerized Maintenance Management System
(NCMMS) as the mandatory repository of record for the PBS RST inventory.
3.​ Enhanced the roles and responsibilities discussion.
4.​ Defined the minimum attributes that must be included in the tank inventory.

Roles and Responsibilities:

1.​ Implementation of this policy is a shared responsibility among PBS offices who
are responsible for incorporating applicable elements into operations, planning
activities, management decisions, and policy development. Assignment of roles
may vary.
2.​ The following offices or teams have responsibility for executing the policy
described in this Order: Office of Facilities Management (OFM), Office of
Architecture and Engineering (OAE); Operations and Maintenance (O&M)
Contractors; Office of Acquisitions Management (OAM); Portfolio Management
(PT); Office of Leasing (PR); Office of the General Counsel (OGC); and PBS
Leadership.
 3.​ A list of the respective offices and responsibilities is found in Appendix A of this
Policy.

7.​ Contracting for RST Services

Contractors often provide tank system services or support to GSA including installation,
O&M, removal, closure, and preparation of plans. Therefore, contract scopes of work
must reflect the requirements included in GSA’s RST Policy. Contractors must be
informed of their responsibilities relative to compliance with GSA’s RST Policy, as well
as expectations to comply with all Federal, state, and local regulations. Per the terms of
the contract, the O&M contractor is responsible for performing the maintenance and
administrative tasks outlined in this desk guide. While contracts for RST services
require contract staff to have proper qualifications and certifications to perform work in
compliance with all regulatory requirements, GSA’s liability does not necessarily transfer
to the contractor. Even if a contractor performs the work, GSA can be held liable for
work performed on GSA property. Therefore, GSA Building Managers and Contracting
Officers Representatives are required to provide proper oversight of contractors to
ensure compliance with the GSA RST Policy and applicable regulations.

A-15
 8.​ RSTs at GSA Leased and Delegated Properties
Lessors and agencies with delegated O&M authority are required to comply with all
applicable RST Federal, state, and local jurisdictions’ regulatory requirements. GSA
shall ensure that language mandating compliance with regulatory requirements is
included in leases and delegation agreements. If language in the agreement is not
specific to RSTs, it must clearly state that operations will be conducted in compliance
with all applicable regulations and GSA policies.

9.​ Notifications for Planned RST Activities

Notifications must be made to the appropriate authorities when making changes such
as tank installation, closure, and removal. Field staff shall consult state and local
agencies for specific requirements as they may vary by jurisdiction. Notification shall be
made only when required by a regulatory implementing agency. The following minimum
notifications must be made to the respective regulatory authorities:
9.1.​ ASTs
●​ Notifications shall be made as specified by the state and local regulator.
o​ State requirements, when applicable, vary and are typically
associated with permitting and registration. States often require
that tanks be registered within 30 days of installation.
o​ Although not a notification per se, some states require
owner/operators to submit Spill Plans.
●​ There are no specific Federal EPA requirements other than the
Emergency Planning and Community Right-to-Know Act (EPCRA) and
SPCC Plan.
9.2.​ USTs
●​ Within 30 days of bringing a tank into use (40 CFR 280.22); and
●​ At least 30 days before beginning either permanent closure or when there
is a change in the product stored in the UST (40 CFR 280.71).

10.​ Installation and Operations & Maintenance Requirements2

The compliance date to meet regulatory installation and operations requirements is
dependent on when the RST was installed or brought into operation. Decisions to
upgrade or remove an existing tank shall be determined individually by applying the
following criteria: (1) potential for harm (considerations include if tank has properly
functioning monitoring/spill prevention equipment, age, condition, performance records,
etc.), (2) ownership/operator responsibility (3) future plans for the building
(considerations include excessing, major renovations where tank removal/upgrade is or
can be included, etc.). Funding tank system replacement or upgrades shall be
prioritized based on the criteria described above.
2
This Desk Guide and PBS Order 1095.2A provide general information on regulatory requirements.
Except where more stringent, these documents do not replace, or supersede any Federal, state or local
regulations or requirements. Users must consult Federal, state, local and jurisdictional governing
standards for full requirements. State regulations may be more stringent than Federal requirements.

A-16
 ○​ When a new non-petroleum HST is needed and where regulations allow,
and based on the intended use, preference should be given to
replacements in the following order (1) double walled AST; concrete
vaulted AST or subterranean AST; and (2) UST (double-walled fiberglass
reinforced plastic).

○​ RST installation shall be in accordance with applicable laws, codes, and

manufacturer’s instructions and performed by qualified contractors, based
on state requirements. All components of the RST system must be
constructed of or lined with materials compatible with the substance to be
stored in the tank. Once installed, tank systems shall be marked with the
appropriate hazard warnings in accordance with OSHA and NFPA
standards, maintained in accordance with applicable regulations and
operated in a manner to reduce or prevent potential releases to the
environment.

10.1.​ ASTs
10.1.1.​ Installation
AST design, installation and operation shall be conducted in accordance with 40
CFR 112.12 (a)-(c) and all applicable industry standards and local codes, including
applicable rules set forth in the following publications: Occupations Safety and
Health regulations (29 CFR 1926.152(i)), National Fire Protection Association
(NFPA) 30, 30A, 31 and 704, International Fire Code (IFC) and other applicable
standards; see the Related Publications listed in this Desk Guide for additional
applicable standards and codes. NFPA rules cover installation and operation
standards for storage tanks, oil handling systems, and oil burning equipment.
Installed ASTs must be certified to meet Underwriters Laboratory (UL) Standard
2085 and include a manufacturer’s warranty. State and local regulatory agencies
may have specific installation requirements; consult with these agencies to
determine additional requirements, if any.

GSA requires that ASTs have secondary containment.

●​ Open containment systems must be capable of
containing the contents of the largest tank - plus an
additional volume calculated based on potential rainfall events when applicable.
●​ Containment areas must not be used for storage of equipment (i.e., spill
response equipment, ladders, buckets, etc.) that will reduce the capacity of the
secondary containment area.
●​ Operators must monitor and release accumulated rainwater, maintain and test
valves, and keep discharge logs.
●​ Based on state or local requirements use of double-walled tanks may eliminate
the need to maintain secondary containment areas.

A-17
 10.1.2.​ Operations and Maintenance
ASTs are required by GSA to include spill and overfill protection, release detection,
secondary containment protection and corrosion protection as needed. Written
procedures must also be in place for testing and inspecting ASTs and conducting
tank repairs. Consult the state agency for specific AST O&M requirements.
10.1.2.1.​ Designated point of contact. Someone at each facility must be
designated in writing who is responsible for discharge
prevention.
10.1.2.2.​ Spill and Overfill Protection. Follow tank management standards
(e.g., American Petroleum Institute) and include a secondary
containment area for visual detection of spills and leaks. Where
dictated by oil storage capacity, the facility must have a SPCC
Plan prepared.
10.1.2.3.​ Secondary Containment. At a minimum, one of the following
prevention systems, or its equivalent, must be used as a means
of secondary containment:
●​ Open secondary containment walls;
●​ Closed secondary containment (for double-walled tanks);
●​ Dikes, berms, or retaining walls sufficiently impervious to
contain oil;
●​ Curbing or drip pans;
●​ Sumps and collection systems (only with Professional
Engineer approval);
●​ Culverting, gutters, or other drainage system (only with
Professional Engineer approval);
●​ Spill diversion ponds or retention ponds (only allowed with
Professional Engineer approval).
10.1.2.4.​ Testing and Inspections. Test and inspect aboveground RSTs
on a routine basis and when repairs are made. The frequency
is commonly defined by the state and local governing authority
or the SPCC Plan. In the absence of an established frequency,
Tanks shall be tested or inspected by a third-party at least every
three (3) years.
Per 40 CFR 112.8(c)(6), examples of integrity tests include, but
are not limited to: visual inspection, hydrostatic testing,
radiographic testing, ultrasonic testing, acoustic emissions
testing, or other systems of non-destructive testing.
10.1.2.4.1.​ Industry standards must be used to determine the
qualifications of persons performing the test and type of
test or inspection. Third-party inspectors must be trained
in the state-specific inspection protocols and perform
inspections that meet these standards. Where a state

A-18
 third-party program exists, training must be comparable
to the training required for state inspectors.
Possible sources of training and certification may include
Standards Developing Organizations such as the
American Petroleum Institute, Petroleum Equipment
Institute, Steel Tank Institute, state regulatory agencies,
and state sanctioned third-party private sector inspection
companies.
10.1.2.4.2.​ In-house visual inspections
are required to be conducted
and documented by O&M
contractors for all RSTs
monthly (i.e. every 30-days).
During these inspections,
look for signs of leaks, stress fractures, stressed
vegetation, visible water in the secondary containment
area and proper tank labeling/marking (EPA, NFPA,
OSHA Hazard Warnings, etc.). Inspections must be
documented in accordance with the recordkeeping
requirements described below and the PM and Job Plans
within NCMMS.
10.1.2.5.​ Tank Repairs. All tank repairs must be performed by qualified
contractors who are certified to make repairs to the specific
equipment they are repairing, in accordance with the tank
warranty. Consult the state agency for specific tank repair
reporting requirements. Note: Reporting requirements differ for
facilities that are covered by a SPCC Plan.
10.2.​ USTs
10.2.1 Installation
New UST systems must be installed in accordance with Federal, state, and local
requirements, industry codes and standards, and manufacturer’s instructions. All
tanks must be designed, constructed and installed by licensed and certified installers
in accordance with all applicable parts of 40 CFR 280.20. USTs must be UL
Certified and carry a manufacturer’s warranty. UST installation and operation must
also comply with applicable NFPA and IFC codes and industry standards. This
includes, but is not limited to, spill and overfill control, corrosion protection, release
detection, and secondary containment.
The preferred type of UST is a double-walled fiberglass reinforced plastic (FRP)
tank. The tank and all ancillary equipment must be compatible with the substance to
be stored in the tank (40 CFR 280 32). In addition to meeting the requirements for
all USTs (40 CFR 280.40), FSTs must also meet the requirements of 40 CFR
280.41, and in accordance with GSA’s RST Policy (PBS Order 1095.2A), be

A-19
equipped with interstitial monitoring and an automatic tank gauge (ATG) system.
Hazardous Substance Tanks must meet the additional requirements listed in 40 CFR
280.42.
USTs that were previously installed (existing tanks) must comply with one of the
upgrade options found in 40 CFR 280.21. Options for continued use of existing
USTs:

●​ Replace with a new UST that meets the performance standards under §
280.20;
●​ Upgrade in accordance with the requirements in paragraphs (b) through
(d) of 280.21; or
●​ Permanently Close the tank in accordance with requirements under
subpart G of Part 280, including applicable release response and
corrective action requirements under Subpart F of 40 CFR 280.

NOTE: Tanks with inoperable/malfunctioning ATGs and/or interstitial monitoring

systems that do not provide for continuous 30-day report do not satisfy the
continuous 30-day monitoring requirement.
10.2.1.​ Operations and Maintenance
Tank systems shall be operated and maintained to reduce and prevent releases.
Tank systems are a complex collection of mechanical and electronic equipment that
can fail under certain conditions. These failures can be prevented or quickly
detected by following required O&M procedures, including those outlined in the
manufacturer’s instructions, GSA’s Preventive Maintenance (PM) Manual and Job
Plans, PBS Order PBS 1095.2A and this Desk Guide. To minimize potential
environmental liability, it is imperative that tank systems are properly operated,
continuously monitored and maintained to ensure that leaks are avoided or quickly
detected. The following provides an overview, the cited regulations should be
consulted for more complete information.
10.2.1.1.​ Spill and Overfill Protection (40 CFR 280.30). Measures to
prevent spills and overfill include monitoring filling operations
and ensuring that the amount of open capacity in the tank is
greater than the amount of product being added. In addition,
overfill prevention equipment is required, including an overfill
alarm, an overfill prevention device (such as a fill limiter), and a
spill bucket. [(40 CFR 280.20(c)(1) - (4)]
10.2.1.2.​ Corrosion Protection (40 CFR 280.31). USTs constructed of
FRP (tanks and piping) do not require corrosion protection
measures as FRP does not corrode. Steel UST systems (tanks
and piping) must be designed to prevent leaks and releases
during the tank’s lifetime. To ensure corrosion protection is
effective:
●​ Use a recognized tank industry standard for inspections;

A-20
 ●​ Test cathodic systems within six (6) months of installation
and every three (3) years thereafter by a qualified inspector;
●​ Inspect impressed current cathodic protection system every
60 days; and
●​ Maintain records to demonstrate compliance in NCMMS.
10.2.1.3.​ Release Detection (40 CFR 280 Subpart D). All tank systems
must meet the leak detection general requirements applicable to
all USTs in 40 CFR 280 Subpart D. In addition to the general
requirements, FSTs must meet the leak detection requirements
for petroleum tanks (40 CFR 280.41) and hazardous
substances tanks must meet the additional requirements found
in 40 CFR part 280.42. Any UST system that cannot comply
with the release detection requirements of this regulation must
complete the closure procedures in subpart G of this subpart.
10.2.1.3.1.​ All Regulated Substance Tanks must meet the
requirements of the GSA Policy and based on the
product to be stored, the applicable section of 40 CFR
280.41. Each tank system must include an ATG to
monitor for releases. Other methods can be used in
conjunction with an ATG if the method can detect a
release from any portion of the tank and the connected
underground piping. The methodology used must detect
releases from any portion of the UST system that
contains product, and must be installed, calibrated,
operated, and maintained as specified in the
manufacturer’s instructions.

10.2.1.3.2.​ Piping release detection must be monitored in

accordance with automatic line leak detectors (for
pressurized piping systems), line tightness testing, and
applicable tank methods. Suction piping systems that
meet specific design criteria (i.e., below grade, product
drains back into the tank once suction is released, etc.)
do not require release detection equipment (40 CFR
280.41(b)(ii)). Additional FST piping release detection
options are outlined in 40 CFR 280.41, and in 40 CFR
280.42 for HST piping.
NOTE: Unless specifically designed and equipped to do so, ATGs do not monitor
leaks on piping systems.

10.2.1.4.​ Testing and Inspections. UST systems must be periodically

inspected by qualified licensed contractors during normal
operations and after certain repairs to verify proper operation
and environmental compliance in accordance with Federal,
state, and local requirements. The frequency of inspections
must also be in accordance with applicable regulatory
requirements. Examples of testing and Inspections include, but
are not limited to:
10.2.1.4.1.​ Monthly: O&M vendor conducts an operation and
maintenance “walkthrough inspection” of UST spill
prevention and release detection equipment, which must
be conducted and documented at least every 30-days.
Checks include removing debris, looking for damage,
loose caps, spills in interstitial space, and properly
functioning alarms. Inspections and any testing shall be
conducted in accordance with a standard developed by a
nationally recognized association or independent testing
laboratory as described in 40 CFR 280.36.
10.2.1.4.2.​ Annually: Leak Detection controls must be tested by the
O&M vendor or by a qualified licensed third party
contractor to check for proper performance which
includes testing alarms and battery backup; checking
probes and sensors; and testing automatic line leak
detectors for compliance (§ 280.44(a)).
10.2.1.5.​ Tank Repairs (40 CFR 280.33). UST repairs shall be performed
as needed to prevent releases due to structural failure or
corrosion in the UST system. Approved repairs must comply
with 40 CFR 280.33, and include the following:
●​ Conducted in accordance with a recognized tank industry
standards or an independent testing laboratory;
●​ Fiberglass-reinforced plastic tanks may be repaired by the
manufacturer's authorized representatives, in accordance with

A-23
 nationally recognized association codes or practices, or
independent testing laboratory;
●​ Replace metal pipe sections and fittings that have corroded or been
damaged and resulting in a release (fiberglass pipes and fittings
may be repaired in accordance with the manufacturer's
specifications).
●​ Performed tank and piping tightness testing within 30 days of
repairs; and
●​ Tested cathodic protection on a repaired tank system within 6
months of completing repairs.

11.​ Emergency Planning and Reporting

11.1.​ Spill, Prevention, Control, and Countermeasure (SPCC) Plans
GSA sites that store oil (as defined in 40 CFR 112.2) and meet the following criteria
are required to prepare and maintain a SPCC Plan:
●​ Based on the location, the facility could reasonably be expected to
discharge oil into or upon waters of the United States. See 40 CFR 120.2);
and
●​ The total aggregate aboveground oil storage capacity exceeds 1,320
gallons (calculation includes containers with a capacity of 55 gallons or
more, even if not filled) OR the total underground FST capacity is greater
than 42,000 gallons of oil.
11.1.1.​ Each SPCC Plan is unique to the facility, however each must
minimally comply with the requirements of 40 CFR Part 112. The
general requirements for the plan can be found in 40 CFR Part 112.7
which include the following:
▪​ Description of the facility layout and diagram
▪​ Operating procedures that the facility implements to prevent oil
spills;
▪​ Control measures installed to prevent oil from entering navigable
waters or adjoining shorelines; and
▪​ Countermeasures to contain, clean up, and mitigate the effects of
an oil spill that has an impact on waters of the United States or
adjoining shorelines.
11.1.2.​ Preparation and implementation of the SPCC Plan is the
responsibility of the facility owner or operator but is often prepared by
a contractor and certified by a licensed professional engineer.
Facilities that meet the Tier I or II criterion have the option to
self-certify their plan (40 CFR 112.3(g)).

A-24
 11.1.3.​ SPCC Plans must be reviewed and evaluated at least every five
years and amended to include more effective field-proven control or
prevention technologies if they exist at the time of the review. In
accordance with EPA regulations, the signed statement can be
placed either at the beginning or end of the Plan or in a log or an
appendix to the Plan. The following words will suffice, “I have
completed review and evaluation of the SPCC Plan for (name of
facility) on (date) and will (will not) amend the Plan as a result.”
Plans must also be amended whenever there is a change in the
facility design, construction, operation, or maintenance that affects
the potential for an oil release (40 CFR 112.5). Completion of the
plan review must be documented and can be satisfied by a signed
statement as to whether the plan will be amended. Amendments
must be made within six months of either of the aforementioned
events. The SPCC Plan shall be tracked and maintained in the
Certificate Module of the NCMMS.
11.2.​ Release Reporting
When a release from an RST system occurs, GSA designated personnel or
representatives shall implement the site-specific spill response actions and initiate
internal notification procedures. Releases include but are not limited to suspected
releases (40 CFR 280.50), overfills and spills (40 CFR 280.53), and confirmed
releases (40 CFR 280.61); In addition, personnel shall refer to the GSA Risk
Management Notification Policy (PBS 2400.1) for GSA Risk Management
Notification requirements.
11.2.1.​ Internal Release Reporting
In the event of a suspected release, overfill and spill, and/or
confirmed release, on-site or field office personnel shall notify EHSF
Managers at the time of discovery. EHSF Managers shall inform the
GSA Risk Management Division of any releases subject to external
reporting within 24 hours of discovery. Additional notifications
include:
●​ The appropriate regulatory authorities as described below in
External Release Reporting;
●​ The Office of Mission Assurance; and
●​ The Office of Architecture and Engineering. To aid in updates
to the Building Information Modeling, asset and site-specific
drawings, and planning for future project delivery.
11.2.2.​ External Release Reporting
Federal, state and local authorities may need to be notified if a spill or
release meets certain criteria, including:

A-25
 ●​ EHSF Managers are responsible for assisting in determining if a release
must be reported to external authorities and provide guidance on
appropriate response activities.
●​ If your facility releases a hazardous substance (equal to or in excess of a
reportable quantity (refer to 40 CFR 302.4) or an extremely hazardous
substance (EHS) call the National Response Center (1-800-424-8802)
within 24 hours. The threshold planning quantity for fuel is typically
10,000 pounds (40 CFR 355.30),
●​ For releases of an EHS over the threshold planning quantity, also notify
the state emergency response commission (SERC), local emergency
planning committee (LEPC), and local fire department.
●​ Facilities covered by a SPCC Plan must also report the following:
-​ If your facility releases more than 1,000 gallons of oil in a single
discharge, contact the Environmental Protection Agency (EPA)
Regional Administrator within 60 days.
-​ If your facility releases more than 42 gallons of oil in two discharges
within any 12-month period, contact the EPA Regional
Administrator within 60 days.
-​ For either of the above SPCC Plan incidents, the EPA Administrator
may require that the SPCC Plan be amended.

12.​ Tank Closure Requirements

Any RST system that does not meet the applicable performance standards or that has
been out-of-service for more than one year, may be subject to continued monitoring and
maintenance, upgrade or formal closure requirements. All tank removal, abandonment,
and closure shall be conducted in accordance with applicable Federal, state, and local
requirements and performed by contractors licensed to perform such work.
12.1.​ AST Closure Requirements
The closure of ASTs is primarily dictated by the local governing authority. Consult
the state agency (or SPCC Plan) for specific requirements. Generally, if an AST has
remained out of service for a year or more, many states require owners to maintain
and monitor the tank, declare the tank inactive, or remove it. If the tank is declared
inactive, substances are removed from the AST system (including pipes) and the
inside of the tank is cleaned. Tanks are secured by bolting and locking all valves
and capping all gauge openings and fill lines. Tanks are also clearly labeled with the
date and the words “Out of Service.” Samples may be required when removing
tanks to determine if any contamination has occurred. Most states require
out-of-service tanks to be inspected and meet leak detection requirements before
they are put back into service.
12.2.​ UST Temporary and Permanent Closure Requirements
USTs must be closed in accordance with (40 CFR 280 Subpart G). A UST that is
out of service for up to 12 months is considered temporarily closed. When a UST
has been temporarily closed for 12 months or more or if it cannot be upgraded to
meet the new UST system requirements, it must be permanently closed. Listed

A-26
 below are highlights of the requirements that must be performed during temporary
and permanent closure. Refer to the cited reference for the full list of requirements.

●​ Remove tank from ground or fill tank with an inert solid; and
●​ Maintain closure documentation.

13.​ Administrative and Recordkeeping Requirements

13.1.​ National Computerized Maintenance Management System Records
The NCMMS is the system of record for the RST program. For the purpose of
compliance with PBS Order 1095.2A, the NCMMS shall contain sufficient pertinent
details to assess the compliance status of the RST program. This includes building
identifying information, tank maintenance records, training, registration records,
release prevention and response information, and a comprehensive inventory. This
data may be housed in various sections within the NCMMS including as general
asset information or in dedicated data fields, in PMs, Job Plans, Certificates, and as
Specifications and Attributes.

In addition to the administrative records and work orders that are maintained in the
NCMMS, some records associated with SPCC Plans or other release prevention and
response plans, transfer procedures or signage, must also be readily available
outside of the NCMMS as necessary such as the posting of signs on tanks. The
Building Manager and COR are required to ensure that O&M vendor performs
maintenance tasks and develops records specific to the tanks that they manage, and
for verifying that the required data is maintained in the NCMMS.

A-27
 13.2.​ Training
Records verifying completion of training or retraining for GSA and O&M vendor staff
must be maintained in the NCMMS Certificates Module. The records, at a minimum,
must identify the name of trainee, date trained, training topic, operator training class
completed, the name of the trainer or examiner and the training company name,
address, and telephone number. If applicable, state specific training guidelines are
available by contacting GSA Environmental Program Managers.
Properties with GSA owned or operated USTs must also have O&M contractor
personnel designated for each class of UST Operator. All UST Operators must
successfully complete the appropriate operator training for their assigned operator
class, as prescribed by the EPA in 40 CFR 280 Subpart J. Operator training must be
evaluated via examination or practical demonstration. Based on the operator class,
topics may include discussions on financial responsibility, familiarity with building,
state and local emergency response procedures. (e.g., release notification, product
transfer, overfill, shutoff, release response, SPCC Plan, etc.), product compatibility,
recordkeeping, and various aspects of operations and maintenance. Training must
meet the requirements of 40 CFR 280.242 listed below:

●​ Class A Operators – responsible for managing resources and personnel

and performing activities such as establishing work assignments to
achieve and maintain compliance with regulatory requirements. Requires
knowledge and skills to make informed decisions through understanding
the purpose, method and function of aspects of the tank operation,
maintenance, and recordkeeping requirements for UST systems. Training
must comply with 40 CFR 280.242 paragraphs (a)(1) and (2);
●​ Class B Operators – responsible for field implementation of applicable
UST regulatory requirements and carries out day to day aspects of
operating, maintaining, and recordkeeping for USTs. Requires
knowledge and skills to recognize and implement applicable UST
regulatory requirements for the assigned UST systems in accordance
with all applicable sections of 40 CFR 280. Training must comply with 40
CFR 280.242 paragraphs (b)(1) and (2); and
●​ Class C Operators – responsible for the first line of response when
emergencies occur. Requires knowledge of actions to take (including
notifying appropriate authorities) in response to emergencies or alarms
caused by spills or releases from the operation of a UST system. Training
must comply with 40 CFR 280.242 paragraphs (c)(1) and (2)

All AST operators (typically oil-handling personnel) must be familiar with their
site-specific filling and spill response procedures including:

●​ Operation and maintenance of equipment to prevent discharges; response

procedures;
●​ Applicable laws, rules, and regulations;

A-28
 ●​ General facility operations; AND
●​ If the facility is subject to the requirements of a SPCC Plan, personnel
must be trained on release prevention topics in accordance with 40 CFR
112.7 (f); and
○​ Contents of the SPCC Plan; and
○​ Annual briefings to ensure understanding of the SPCC Plan.

13.3.​ Maintenance Records and Guides

The building management staff shall ensure that records of maintenance performed
on RSTs by O&M contractors are maintained in the NCMMS and that Preventive ​
Maintenance Guides contain job plans for all recurring environmental regulatory
related maintenance and administrative federal compliance related activities. ​ ​
Sample RST activities records that must be maintained include all testing and ​
repairs performed on tank systems, and any operational guidance documents (e.g.,
filling procedures, training, tank registration and spill prevention and response
plans). When tank registration is required, include a copy of registration form,
expiration and renewal information, and renewal due date notification in NCMMS
Certificate Module. Records to be maintained include:
●​ Copies of tank notifications and reports to Federal and state agencies
(e.g., installation, closure, leaks, spills, EPCRA, Tier II Reports, etc.);
●​ Scheduled ongoing data reviews, inspections, leak detection tests and
repairs and records of the same;
●​ Copies of UST Operator training certificates;
●​ Written reporting procedures for notifications of releases and data tracking
and work orders related to SPCC Plans or written plans for other release
mitigation and responses (including documentation of annual reviews);
●​ PM Guides to include recurring activities such as but not limited to
inspections, permits/registration renewal, training renewal;
●​ Written Filling/transfer procedures;
●​ Records of tanks that need or have planned upgrades, replacements,
closure; and
●​ Records of internal reporting of RST related data to the EHSF Office.
13.4.​ Tank Inventory
Building Managers shall develop and maintain within the NCMMS a comprehensive
inventory of all RSTs at GSA-controlled federally owned facilities. The inventory will
contain the information described below. The inventory shall be updated as needed to
ensure that the recorded data reflects the most current conditions related to each
tank. The inventory of tanks located in facilities where GSA has delegated O&M
authority to the occupant agency will be maintained electronically by that agency and
made available to OFM Facilities Operations Office upon request. The minimum data
required for the GSA maintained tank inventory is listed in Table 3 below.
