Background

In 1941, the U.S. Government deeded approximately 5,000 acres of vacant desert in the southeastern part of the Las Vegas Valley that would become the site of the world's largest magnesium plant - a plant that played a critical role in the World War II effort.  Following the war, portions of the plant and adjacent land were leased to various industrial, government and business entities primarily involved in the production of chemicals and products containing chemicals.

During the ensuing years, operations at these plants produced a variety of industrial and municipal effluents that were historically disposed of on-site in unlined evaporation ponds, transported off-site via ditches, or disposed of on the land surface.

These disposal practices were industry-standard and legal at the time. Some of the wastes migrated into the Las Vegas Wash, a waterway that flows into Lake Mead, a primary source of drinking water for southern Nevada and millions of downstream users. Current waste disposal practices are consistent with all local, state and federal guidelines and regulations.

Since the 1970's, the Nevada Division of Environmental Protection (NDEP) has provided oversight for the remediation of soil and groundwater impacted by the legacy contaminants from each of the sites which make up the BMI Complex.  The NDEP's Bureau of Industrial Site Cleanup was formed in 2015 to continue this effort and currently oversees remediation activities for Basic Remediation Company, Titanium Metals Corporation, Nevada Environmental Response Trust, Pioneer Americas, LLC d/b/a Olin Chlor Alkali Products, and Endeavour.

Some of the companies which operate out of the BMI Complex include Olin Chlor Alkali, NERT, and TIMET.
Pioneer Americas, LLC d/b/a Olin Chlor Alkali Products; NERT; and TIMET are some of the companies located within the BMI Complex.
