DOMAIN 1: INSTALLATION PLANNING & REGULATORY REQUIREMENTS
(Questions 1-25)
,1. One of the significant causes of leaks in underground liquid storage
systems is:
• A) Age of the tank
• B) Improper installation
• C) Type of liquid stored
• D) Soil conditions
Rationale: Proper installation is critical to UST system integrity. Many leaks
and premature failures can be traced directly to installation errors, which is
why certification and training are emphasized for installers.
2. Written Plans are required to:
• A) Obtain permits, solicit bids, and provide precise guidance for
installers
• B) Satisfy insurance companies only
• C) Document the tank warranty
• D) Schedule delivery of the tank
Rationale: Detailed written plans serve as the foundation for a successful
installation. They ensure regulatory compliance, enable accurate bidding, and
provide installers with clear specifications to follow.
3. The plans should include:
• A) The color of the tank and dispenser
• B) Describe the property, identify the size and location of the
tanks, indicate the liquids to be stored and provide the location of
the dispensers and piping
• C) Only the tank size and depth
• D) Only the type of piping to be used
,Rationale: Comprehensive plans must cover all aspects of the installation
including site description, tank specifications, stored product types, and all
system components' locations.
4. Storage systems discussed in this recommended practice are usually
regulated by:
• A) Only the EPA
• B) Only state agencies
• C) Federal, state or local agencies
• D) Only local fire departments
Rationale: UST systems are subject to multiple regulatory levels including
EPA (40 CFR Part 280), state environmental agencies, and local authorities
having jurisdiction. All regulations must be followed.
5. All owners should ensure that the equipment to be installed meets
______ before being installed.
• A) The lowest price point
• B) Applicable regulatory requirements
• C) The installer's preference
• D) Manufacturer's color standards
Rationale: Owners bear ultimate responsibility for ensuring all equipment
meets regulatory standards prior to installation. This is a fundamental
compliance requirement.
6. Consult the local authorities who have jurisdiction in the area before
storage-system plans are:
• A) Written or drawn
• B) Finalized or construction is initiated
, • C) Submitted for bidding
• D) Reviewed by the owner
Rationale: Early consultation with authorities helps identify local
requirements and avoids costly modifications after plans are complete or
construction has begun.
7. Which federal regulation governs UST installation and retrofitting?
• A) 40 CFR Part 280
• B) OSHA 1910
• C) NFPA 30
• D) ASTM D698
Rationale: 40 CFR Part 280 is the EPA regulation that establishes technical
standards and corrective action requirements for underground storage tanks.
8. A "Class A" operator is responsible for:
• A) Daily inspection of the UST system
• B) Overall management and implementation of the UST system
• C) Responding to alarms
• D) Installing new tanks
Rationale: Class A operators have broad responsibility for the management
and implementation of the UST system, including knowing the regulations and
ensuring compliance.
9. A "Class B" operator is responsible for:
• A) Only paperwork
• B) Daily operations, maintenance, and recordkeeping
• C) Overall system management
