ENVIRONMENTAL ACTIVITY The extensive activity in the deepwater GOM requires thorough scientific knowledge and careful environmental considerations. The Environmental Studies Program (ESP), initiated in 1973, gathers and synthesizes environmental, social, and economic information concerning offshore oil and gas activities. The ESP expanded its focus to address particular issues as industry moved into deepwater. For example, studies were begun to evaluate the sensitivity of chemosynthetic ecosystems. Refer to Appendix D for a listing of selected deepwater environmental studies. A biologically based grid system was developed as part of a comprehensive strategy to address deepwater issues. The grid system divided the Gulf into 18 areas or "grids" of biological similarity (figure 13). Under this strategy, the MMS will prepare a programmatic environmental assessment (PEA) to address a proposed development project within each of the grids. These grid PEA’s are comprehensive in terms of the impact-producing factors and in terms of the environmental and socioeconomic resources described and analyzed for the entire grid. Other information on publicly announced projects within the grid is discussed, as well as any potential effects expected from their future developmental activities. Projects selected for the grid PEA’s are representative of the types of development expected for the grid. For example, a good candidate for a grid PEA would be a proposed development of a new surface structure that might serve as a "hub" for future development within the grid. Once a grid PEA has been completed, it will serve as a reference document to implement the "tiering" concept detailed in the National Environmental Policy Act’s (NEPA's) implementing regulations. Future environmental evaluations may reference appropriate sections from the PEA to reduce duplication of issues and effects addressed in the grid NEPA document. This will allow the subsequent environmental analyses to focus on specific issues and effects related to the proposals. Table 2 below shows the status of the grid PEA’s.

The NTL requirements apply to activities in water depths greater than 400 m (1,312 ft) in the Central and Western Planning Areas of the GOM. 21
