SECTION 1: GENERAL INSTALLATION PRINCIPLES
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
Answer: B. Improper Installation
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
Answer: A. Obtain permits, solicit bids, and provide precise guidance for
installers
,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
Answer: 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
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
Answer: C. Federal, state or local agencies
Rationale: UST systems are subject to multiple regulatory levels including EPA (40
CFR Part 280), state environmental agencies, and local authorities having
jurisdiction .
,5. Which EPA regulation specifically governs the design, installation, and
operation of new underground storage tanks (USTs) in the United States?
A) 40 CFR Part 260
B) 40 CFR Part 280
C) 40 CFR Part 1910
D) 40 CFR Part 500
Answer: B. 40 CFR Part 280
Rationale: 40 CFR Part 280 is the EPA's primary regulation for UST systems,
covering design, installation, operation, and closure requirements .
6. Under state permitting requirements, what is the typical time frame for a
local authority to issue an installation permit after a complete application is
submitted?
A) 5 business days
B) 15 calendar days
C) 30 calendar days
D) 60 business days
Answer: C. 30 calendar days
Rationale: Most states stipulate a 30-day period to review and issue a UST
installation permit, provided the application is complete and meets all criteria .
7. PEI/RP100 is a code standard used primarily in which country?
A) United States
B) Canada
C) United Kingdom
D) Australia
Answer: A. United States
, Rationale: PEI/RP100 is a US standard for the installation of underground liquid
storage systems, widely referenced in UST regulations and installation practices .
8. Which API standard provides guidelines for the design, fabrication, and
testing of steel underground storage tanks?
A) API 650
B) API 1615
C) API 620
D) API 653
Answer: B. API 1615
Rationale: API 1615 specifically addresses underground steel storage tanks,
covering design, construction, and testing. API 650 covers aboveground storage
tanks .
9. Tank installers should have gone through training programs to improve their
skills and ensure the install is __________.
A) Inexpensive
B) Fast
C) Successful
D) Visually appealing
Answer: C. Successful
Rationale: Formal training programs equip installers with the knowledge and skills
necessary for successful installations that meet all regulatory and safety
requirements .
