Specifications include, but are not limited to: Work includes management of de minimis oil and gas exploration and production (E&P) waste at the surface (e.g., dry or weathered crude oil at depths less than two feet deep) only to the extent necessary to perform work related to reclamation, as described in this solicitation. If the Contractor discovers existing, historic contamination from former oil and gas operations at the Location during execution of the work (e.g., saturated oily soil, petroleum-impacted soil exceeding a depth of two feet, produced water-impacted soil that would potentially preclude establishment of vegetative cover, or petroleum impacted soil extending down to shallow groundwater), then the Contractor shall immediately notify the Project Manager. Removal or remediation of extensive, existing, historic contamination beyond the work areas required by the Contractor to execute the Scope of Work in this solicitation is not included in the Scope of Work for this project.
