The purpose of the Containing Effects of Mineral Extraction Act of 2026 is to regulate large-scale mineral extraction projects, particularly those located near urban communities. The law aims to ensure that these projects do not negatively impact local transportation, air quality, noise levels, and water resources. It sets specific requirements for companies seeking to sell mineral materials or obtain permits for these projects. Key provisions of the law require project operators to submit detailed assessments and plans to the Secretary of the Interior before they can proceed.
