Various different thresholds may be defined for different aspects of the project depending on the type of noise and vibration source and whether the source is temporary or permanent. These studies involve defining ‘significance thresholds’ for determining acceptable noise and vibration levels. We are familiar with the EIR/EIS study process. Our work has involved producing noise studies for large community development projects, retail centers, mining sites, and oil and gas development projects. We recognize that noise and vibration problems are best solved in the planning stages of any project. We provide Environmental Impact Statement (EIS) and Environmental Impact Report (EIR) noise studies for inclusion National Environmental Policy Act (NEPA) and California Environmental Quality Act (CEQA) studies.
