Trenching continued at Stream Crossing #14 (EMP 20.52) Installation of concrete-coated pipe continued from the east side of the Lebec I-5 bore (EMP 20.77). Excavation in the Tejon Wetland (EMP 20.73 to 20.60) was completed. Excavation for the bore pit on the east side of Grapevine I-5 (EMP 13.31) continued. Pot-hole activities occurred between EMP 10.96 to 10.60 (up to Laval Road truck stop).
In San Joaquin kit fox habitat (EMP 0.0 to 15.5) wildlife ramps are being installed in open trench and the PPSI biologist checks the trench each morning prior to the start of work to ensure no wildlife is trapped in the trench when construction begins.
Work continued on the foundation of the Emidio Pump Station (EMP 0.0). Grading at the Grapevine Pump Station (EMP 15.51 to 15.57) was halted while asbestos-coated pipe that was discovered during potholing was removed and disposed of by a licensed hazardous materials operator.
