Open: 33% | Closed: 67%

Final Report Released On: December 19, 2022

2020-02-I-TX-1

For all TPC PNO terminal operations in high-purity butadiene service (e.g., greater than 80 percent butadiene concentration), develop and implement a program to identify and control, or eliminate, dead legs. At a minimum, the program must require:

a)   a comprehensive review of equipment configurations in high-purity butadiene service using both Piping and Instrumentation Diagrams (P&IDs) and field evaluations to identify all permanent dead legs. Implement a process to identify changes in operating conditions in high-purity butadiene service that could result in the formation of temporary or new permanent dead legs, such as when primary or spare pumps are temporarily or permanently out of service. Ensure this review is conducted at least every five years;

b)   evaluation and implementation of design strategies, where practical, to prevent dead legs in areas susceptible to popcorn polymer formation;

c)   mitigation, control, or prevention of hazardous popcorn polymer buildup in all identified dead legs in high-purity butadiene service, such as through increased monitoring, flushing of equipment, use of inhibitor(s), or planning maintenance activities to minimize the amount of time that a temporary dead leg is present; and

d)   periodic continual auditing (at a minimum annually) by TPC PNO management to ensure that the process is being implemented.

Revise where necessary the Spill Prevention, Control and Countermeasure (SPCC); Facility Response Plan (FRP); and/or Accidental Release Prevention Program (40 CFR Part 68) rules to prevent impacts to the environment and/or public from spills, releases, fires, and explosions that can occur at bulk aboveground storage facilities storing gasoline, jet fuels, blendstocks, and other flammable liquids having an NFPA 704 flammability rating of 3 or higher.
 
At a minimum, these revisions shall incorporate the following provisions:
 
a) Ensure bulk above ground storage facilities conduct and document a risk assessment that takes into account the following factors:
1. The existence of nearby populations and sensitive environmenls;
2. The nature and intensity of facility operations;
3. Realistic reliability of the tank gauging system; and
4. The extent/rigor of operator monitoring
b) Equip bulk aboveground storage containers/tanks with automatic overfill prevention systems that are physically separate and independent from the lank level control systems.
c) Ensure these automatic overfill prevention systems follow good engineering practices.
d) Engineer, operate, and maintain automatic overfill prevention systems to achieve appropriate safety integrity levels in accordance with good engineering practices, such as Part 1 of lnternational Electro-technical Commission (IEC) 61511-SER ed1.0B-2004, Functional Safety - Safety Instrumented Systems for the Process Industry Sector.
e) Regularly inspect and test automatic overfill prevention systems to ensure their proper operation in accordance with good engineering practice.

Conduct a survey of randomly selected bulk aboveground storage containers storing gasoline or other flammable liquids with a NFPA 704 flammability rating of 3 or higher, at terminals in high risk locations (such as near population centers or sensitive environments) that are already subject to the Spill Prevention, Control and Countermeasure (SPCC) and/or Facility Response Plan (FRP) rules to determine:
a) The nature of the safety management systems in place to prevent overfilling a storage tank during loading operations. Analysis of the safety management systems should include equipment, training, staffing, operating procedures and preventative maintenance programs.
b) The extent to which terminals use independent high level alarms, automated shutoff/diversion systems, redundant level alarms or other technical means to prevent overfilling a tank
c) The history of overfilling incidents at the facilities, with or without consequence
d) Whether additional reporting requirements are needed to understand the types of incidents leading to overfilling spills that breach secondary containment and have the potential to impact the environment and/or the public, as well as the number of safeguards needed to prevent them.
