The District 9 Environmental Unit serves the environmental needs of the Eastern Sierra. It consists of a multi-disciplinary team with specialties in a wide range of areas such as, archeological resources, architectural history, biology, air, noise and water quality, hazardous materials testing, and paleontology. The Unit administers Caltran's responsibilities under federal and state law in response to the enactment of the National Environmental Policy Act (NEPA), in 1969, and the California Environmental Quality Act (CEQA), in 1973. In response to the passage of a host of environmentally related laws and regulations and heightened public support for the environment, these responsibilities have grown to become a substantive and inseparable part of Caltrans' planning, development, construction, operation and maintenance efforts.

NEPA Deligation

What are NEPA and CEQA?

The National Environmental Policy Act (NEPA) defines procedures for environmental review and impact analysis of projects that need approval by federal agencies. The purpose of NEPA is to ensure that environmental factors are weighted equally when compared to other factors in the decision making process. The California Environmental Quality Act (CEQA) does the same for projects that need approval by state or local agencies. Both laws require that the potential environmental impacts of a proposed project be assessed, quantified, disclosed, minimized, eliminated and/or mitigated whenever possible.

The National Environmental Policy Act (NEPA) requires federal agencies pursuant to 40 CFR (Code of Federal Regulation) 1500, to consider potential environmental effects of their programs by preparing an Environmental Impact Statement (EIS).

NEPA's purpose is to:

  • Declare a national policy which will encourage productive and enjoyable harmony between man and the environment
  • Promote efforts which will prevent or eliminate damage to the environment and biosphere and stimulate the health and welfare of man
  • Enrich the understanding of ecological systems and natural resources important to the Nation
  • Establish a Council on Environmental Quality

The California Environmental Quality Act (CEQA) pursuant to Public Resources Code (PCR) Section 21000, requires local and state governments to consider the potential environmental effects of a project before a decision whether to approve a project or not.

CEQA's purpose is to:

  • Disclose the potential impacts of a project to government decision makers and the public about the potential significant environmental effects of proposed activities
  • Suggest methods to minimize those impacts to the environment
  • Identify alternatives to the project
  • Enhance Public Participation
