ES performed an engineering assessment of the Santa Maria Landfill leachate treatment plant (LTP) filters that were not operating effectively. The assessment resulted in a contract for ES to design a new filter system for the LTP. The new filter system design was approved by the City of Santa Maria and will be installed by ES in the next few months. The new filter will allow the system to operate during the upcoming rain season.

ES began work on additional site assessment at the Phillips Ranch Landfill in Pomona California for YK America/Pomona Rancho Development. The site is under the State of California’s Site Designation Committee of Cal EPA and a Remedial Action Plan is already approved for the site. The results of the additional site assessment will be used to amend the existing RAP so site development can begin later in 2006.
