The public involvement program for the Gnoss
Field Airport Proposed Runway Extension EIS and EIR
is designed to enable the FAA and Marin County
to consult effectively with the general public,
concerned interest groups and public agencies
about their views, concerns and ideas regarding
the scope and content of the EIS and EIR and,
ultimately, the adequacy of the EIS and EIR
The proposed extension to Runway 13/31 at
Marin County Airport - Gnoss Field is a Federal
action that requires the preparation of an
Environmental Impact Statement (EIS), in
accordance with the National Environmental
Policy Act (NEPA). In addition, a concurrent
Environmental Impact Report (EIR) is being
prepared in accordance with the California
Environmental Quality Act (CEQA). NEPA and CEQA
give all persons, organizations, and government
agencies the right to review and comment on
proposed actions that are evaluated by an EIS
and by an EIR. This is known as the "Scoping
Process." The scoping process is the initial
step in the preparation of the EIS and the EIR
and is an early and open process for determining
the scope of issues to be addressed and for
identifying the significant issues related to
the proposed action. Therefore, the scoping
process helped to identify:
- Range of actions (project,
- Alternatives - those to be
rigorously explored and evaluated and those
that may be eliminated
- Range of environmental impacts
