Phase I and II Site Assessments and Peer Review Services for Owner of Large Nature Preserve Holdings

PES was retained by The Nature Conservancy (TNC) to conduct environmental assessments of six agricultural properties comprising more than 12,000 acres in Glenn, Merced and Sacramento Counties. We have also provided third party review of previous environmental documentation for another TNC property in Kern County.

These projects have generally included property acquisition for restoration and incorporation into regional nature preserves. Potential environmental concerns identified during the assessments have included the presence of petroleum hydrocarbons in soils and an unpermitted solid waste disposal site. For TNC, PES has conducted soil and groundwater investigations to define the degree and extent of contamination and/or provided oversight of previous property owners’ work prior to transfer to TNC. For the unpermitted landfill, PES used geophysical exploration and trenching techniques to verify the presence of subsurface deposits of contaminants requiring remediation.

Due to the sensitive future use of the property, PES prepared an environmental cleanup plan that was submitted to the local implementing agency and approved. PES’ plan was designed to be consistent with the short- term continued use of the property as agricultural with a phased-in approach for preserve restoration.
