Bechtel Sabine Pass LNG In June, Cheniere Energy gave Bechtel full notice to proceed on the construction of Cheniere’s Train 6 expansion of the Sabine Pass Liquefaction (SPL) project in Cameron Parish, La. Work on the SPL expansion includes construc- tion of a new LNG train and tie-in to existing facilities. The expansion will add 4.5 million tonnes of LNG per year to the plant’s current ca - pacity of 22.5 million tonnes. Bechtel has provided numerous services to Cheniere on the SPL complex since 2006. Additionally, NextDecade awarded Bechtel an EPC contract in May for the first phase of the Rio Grande LNG proj - ect in Brownsville, Texas.

Battelle Navy PFAS Cleanup As part of its continuing environ - mental remediation work for the U.S. Navy at the former Naval Air Warfare Center in Warminster, Pa., Battelle is now under contract to clean up PFAS found at drinking water systems near the site. PFAS, the term for per- and poly - fluoroalkyl substances, are a group of man-made chemicals often used in firefighting foam at airports. Typically, ion exchange or granu- lated activated carbon filtration systems are used to reduce PFAS levels to below detectable levels in drinking-water plants.
