Cause of Problem: Maintenance/Procedures

Motiva's S-2 and S-3 sulfur plants tripped offline while analyzer FI-3677 was being calibrated. During analyzer calibration, air flow was reduced, initiating shutdown of S-2. Acid gas was diverted through to S-3 and pushed into gas knock out drum resulting in shut down of S-3. Acid gas was routed to Coker Flare and Shell's Go-1 flare. Shared incident with SHELL CHEMICAL LP. Emissions included flaring from both facilities.
RQ. Sulfur plants were restarted, operating procedures for safely calibrating instruments will be developed and included in operations training program, training conducted for personnel.

2010-09-09
Point Source(s):
Butadiene Cool Down Line [wharf]

Pollutant(s):
1,3-Butadiene - 21 pounds
Cause of Problem: Corrosion

Report states that "at 1418 on September 9, 2010, Operations noticed an ice ball on an insulated finished butadiene cool down line. This line transports butadiene to the wharf. Once identified, the line was isolated and then de-pressured to the flare system. The cause of the leak was determined to be due to corrosion under the insulation."
RQ. Report states that, "On September 10, 2010, a skinner clamp was installed to temporarily stop the leak...clamp was replaced with an engineered box on September 12, 2010. This section of piping will be replaced during the next scheduled BD-5 unit turnaround. The facility failed to have control facilities in place to prevent the release. This is an area of concern with LAC 33:III.905. Control facilities to be installed when feasible."

2010-08-31
Point Source(s):
alky unit's tank L-431

Pollutant(s):
Sulfuric Acid - BRQ
Cause of Problem: Equipment Failure

Alky unit's fresh sulfuric acid tank L-431 was leaking from a one inch flange on the north side.
BRQ. Refinery letter states that "final calculations confirm that no reportable quantities were exceeded." The fresh and spent acid tanks were equalized to reduce the pressure in the fresh acid tank L-431 to slow the leak rate. Bolts on the leaking flange was replaced, however that did not stop the leak. Therefore, a sealant material was pumped into the nozzle of the leaking flange and was wire wrapped in order to provide a permanent seal. No LDEQ report. Refinery letter only.

2010-08-10
Point Source(s):
UTLX 950070

Pollutant(s):
1,3-Butadiene - 49 pounds
Cause of Problem: Seal or Gasket

The root cause of the release was faulty rail car equipment (rail car UTLX 950070). The gasket on the seat of the relief valve had deteriorated, resulting in a leak. 1,3 Butadiene was released.
Firewater was applied to the leaking car to suppress the vapors. The area surrounding the rail car was sampled for 1,3butadiene and hot zone was established. 5h llm after leak, The gasket on the seat of the relief valve was replaced reducing the leak by 99%. 11h and 49m later it was tightened stopping the leak. To confirm there was no more leaks, rail car UTLX 950070 was soap tested. The material was transferred out of the leaking rail car and off site. Measures were take with the rail scheduler to minimize the time that rail cars will sit on site without being shipped. No LDEQ report. Refinery letter only.

Cause of Problem: Corrosion

LDEQ report states, "Motiva reported a leaking high sulfur light product line at the wharf that released approximately six barrels of naptha to the Mississippi River. Leak was caused by external corrosion, and two contributing factors were identified. First, the line was found to be in contact with the insulation of adjacent piping, causing water accumulation between the lines. Additionally, inadequate coating was discovered on the blistered section of piping." A total of 1,748 pounds of chemicals were released to the air.
RQ. LDEQ report states that "Motiva took the following measures to prevent reoccurrence of this incident: the blistered section of piping will be replaced so it does not contact near-by equipment and the new line will be adequately coated to protect from external corrosion. Motiva has determined that the release was preventable. This incident is an area of concern with regards to LAC 33:III.905 and LAC 33:IX.501.D."
