Step 8: Determine Environmental Review and Preliminary Design Considerations

Illinois Environmental Protection Act

Illinois has its own state environmental policy act, the Illinois Environmental Protection Act (IEPA), which is modeled after NEPA. The IEPA requires that state agencies consider the environmental impacts of their actions, and it also provides for public participation in the decision-making process. In the case of a Design-Build Bridge Bundling project in Illinois that has federal funding, the NEPA process and the requirements of the IEPA would both apply. However, if there is a conflict between the two laws, the requirements of NEPA would take precedence over the requirements of the IEPA since federal law generally preempts state law in such cases.

Some of the key provisions of the IEPA include:

NEPA Process

For federally funded projects, the National Environmental Policy Act (NEPA) is a United States law that requires federal agencies to consider the potential environmental impacts of their actions before making decisions. The NEPA process is a systematic approach used to analyze the environmental effects of proposed federal projects, plans, and policies.

The NEPA process typically involves three levels of analysis: (I) Categorical Exclusion (CE), (II) Environmental Assessment (EA), and (III) Environmental Impact Statement (EIS). The following graphic provides an overview of the NEPA process:

NEPA Process

In addition to NEPA, the following may apply in addition to or in connection with Bridge Bundling projects in Illinois:

Reports

Environmental surveys and reports are useful to determine anticipated environmental impacts of a bridge bundle. Identifying federal or state-protected species present in a project area, conditions present and any required permits that will be needed is critical to mitigation efforts and compliance with federal law.
