SFPP, L.P. operates a petrochemical facility adjacent to the Walnut Creek Channel, north of Imhoff at 1550 Solano Way, Concord. The California Regional Water Quality Control Board, San Francisco Bay Region has required SFPP, L.P. to perform remediation measures to lower toxin levels in the groundwater caused by migration of petroleum hydrocarbons from their facility toward the channel to intercept and breakdown contaminants in the groundwater which migrate toward the channel.  
  
On August 17, 1999, the Board of Supervisors approved a license agreement between the District and SFPP, L.P. that allowed the planting, installing, maintaining, using and removing of poplar trees, irrigation system and monitoring wells in District property to intercept and breakdown contaminants in the groundwater which migrate toward the channel (referred to as a “Phytoremediation System”). There have been three prior amendments to the original license agreement. The first amendment allowed for additional poplar trees, extended the term and increased the yearly fee, and increased the amount of the bond. The second and third amendments upgraded and expanded the Phytoremediation System. This fourth amendment replaces the exhibit showing the locations of the trees and other improvements, extends the term for an additional ten years, through July 31, 2029, and updates the fee schedule for the last ten years of the agreement.  
  

Licensee will not be able to use District property to remain in compliance with the requirements of the California Regional Water Quality Control Board, San Francisco Bay Region.
