Notice of Availability: Well Stimulation Treatments on the Pacific Outer Continental Shelf

BOEM and BSEE are announcing the availability of a Programmatic Environmental Assessment (PEA) and Finding of No Significant Impact (FONSI) for well stimulation treatments (WSTs) on the Pacific Outer Continental Shelf (OCS). This Notice of Availability (NOA) is published pursuant to implement the provisions of the National Environmental Policy Act (NEPA) of 1969, as amended. The PEA evaluates potential environmental effects of WSTs on the Pacific OCS. These activities include: fracturing WSTs (diagnostic fracture injection tests; hydraulic fracturing (e.g., frac pacs); and acid fracturing) and non-fracturing WSTs (matrix acidizing and polymer/surfactant injection). BOEM and BSEE are also issuing a FONSI supported by the analysis in the PEA. The FONSI concludes that the reasonably foreseeable environmental impacts associated with the proposed action and alternatives, as set forth in the PEA, would not significantly impact the quality of the human environment; therefore, the preparation of an Environmental Impact Statement is not required.
