California Environmental Quality Act (CEQA) FAQs

The California Environmental Quality Act (CEQA), enacted in 1970, requires state and local agencies to assess and disclose the environmental impacts of proposed projects. It ensures that environmental factors are considered in decision-making and that feasible measures are taken to mitigate impacts.

We provide end-to-end support including CEQA documentation (Negative Declarations, Mitigated Negative Declarations, and EIRs), air quality impact analyses, greenhouse gas inventories, health risk assessments, and stakeholder engagement to ensure compliance with CEQA guidelines.

Trinity’s CEQA documentation includes air quality modeling, emissions estimates, health risk assessments, and odor evaluations, ensuring all potential impacts are thoroughly assessed and disclosed.

Any business, developer, or public agency proposing a project in California that may affect the environment must comply with CEQA. This includes industrial, commercial, energy, transportation, and land development projects.

While CEQA is California-specific and often more stringent, it is similar to the federal National Environmental Policy Act (NEPA). CEQA requires agencies to disclose environmental impacts and reduce them where feasible, influencing nearly every development project in the state.
