Mitsubishi Cement Corporation South Quarry EIR/EIS Project

Project Overview

ECORP technical staff prepared a joint Environmental Impact Report/Environmental Impact Statement (EIR/EIS) and CEQA and NEPA notices for the Mitsubishi Cement Corporation to ensure compliance with all federal, state, and local environmental regulations during the expansion of an existing limestone quarry in the San Bernardino National Forest. We additionally supported public and agency meetings during the scoping and public comment periods as part of the Mitsubishi Cement Corporation South Quarry EIR/EIS Project.

The EIR/EIS evaluated air quality and greenhouse gasses, biological resources, cultural resources, geology and soil resources, hazards and hazardous materials, hydrology and water quality, mineral resources, noise, recreation, and scenery resources in compliance with the Americans with Disabilities Act (ADA) Section 508. Key issues included the proposed action’s compliance with the Carbonate Habitat Management Strategy, greenhouse gas emissions, and impacts to the Cushenbury herd of bighorn sheep and scenery resources.

As part of the Mitsubishi Cement Corporation South Quarry EIR/EIS Project, ECORP lead an Interdisciplinary Team consisting of representatives of the San Bernardino National Forest, San Bernardino County, ECORP technical staff, and a representative from the California Department of Fish and Wildlife.

The South Quarry project area totaled approximately 153.6 acres and consisted of:

  • A 128-acre quarry
  • A 2.7-acre landscape berm
  • A 22.2-acre haul road,
  • A 1.8-miles in length haul road
  • A temporary construction road of 0.7 acres
