About this file

Written by GovTribe AI · Dec 21, 2023

This document contains an in-service inspection report for an aboveground storage tank (AST) located at the A.A.S.F. #1 Lexington fuel storage facility in Lexington, Oklahoma. The inspection was conducted in accordance with STI SP001 standards to evaluate the integrity of Tank 1, which has a capacity of 20,000 gallons and contains F24 jet fuel. Significant findings included coating failures, improper piping connections, vegetation growing in containment areas, and cracks in the secondary containment floor. The report provides details on the tank construction and components, presents ultrasonic test data and calculations for remaining shell life, and includes appendices with drawings, checklists, and photographs documenting issues found. Required repairs are specified to address safety hazards and compliance deficiencies regarding access, labeling, piping installation, and containment integrity. Recommended repairs are also outlined to prevent corrosion and facilitate future inspections.

STI

SP001

INSPECTION

DETERMINATION

STI

SP001

classifies

tanks

into

three

categories.

tank

ranked

Category

depending

the

risk

tank

Category

tanks

pose

the

least

amount

risk

and

Category

the

highest.

The

inspection

types

and

are

based

the

tank

size

and

tank

The

risk

factors

include

spill

(RPB),

continuous

method

(CRDM),

and

tank

and

(see

definitions

below).

SPILL

CONTROL

‐

means

preventing

release

liquid

into

the

environment,

including

adjoining

and

waterways.

Spill

control

methods

include:

Remote

impounding;

Secondary

containment

dike/berm;

Secondary

AST;

and

Secondary

system.

CONTINUOUS

RELEASE

METHOD

(CRDM)

–

means

CRDM

systems

are

follows:

Release

barrier

(RPB);

Secondary

containment

AST,

including

double‐wall

AST

double‐bottom

AST;

and

Elevated

AST,

with

without

release

barrier.

RELEASE

PREVENTION

BARRIER

(RPB)

–

liquid

barrier

that

installed

the

AST.

Its

purpose

divert

leaks

toward

the

perimeter

the

AST,

where

they

can

easily

detected,

well

prevent

liquid

from

contaminating

the

environment.

RPBs

are

composed

materials

compatible

with

the

liquid

stored

the

AST

and

meet

appropriate

engineering

standards.

Examples

are

steel

(as

steel

tanks),

concrete,

elastomeric

liners,

other

suitable

materials,

provided

the

above

criteria

are

met.

OVERFILL

PREVENTION

‐

Category

tanks

Category

tanks

are

ASTs

with

Category

tanks

are
