Lafarge North America Inc. Clean Water Act Settlement

(Washington, DC - November 29, 2011) Lafarge North America Inc., one of the largest suppliers of construction materials in the United States and Canada, and four of its U.S. subsidiaries have agreed to resolve alleged Clean Water Act violations. The violations include unpermitted discharges of stormwater at 21 stone, gravel, sand, asphalt and ready-mix concrete facilities in Alabama, Colorado, Georgia, Maryland, and New York. Stormwater flowing over concrete manufacturing facilities can carry debris, sediment and pollutants, including pesticides, petroleum products, chemicals and solvents, which can have a significant impact on water quality.

Injunctive Relief

The Decree requires the development and implementation of an extensive management and reporting system designed to provide increased oversight of Lafarge's ground operations and ensure greater compliance with the stormwater requirements for 189 Lafarge facilities.

The program consists of:

  • Training all personnel with operational responsibilities
  • Implementing a management structure with specified inspections and evaluations
  • Reporting on stormwater issues
  • Conducting compliance assessments at all facilities that the company owns and/or operates

Lafarge will also develop and implement a corporate-wide Environmental Management System. EPA estimates that Lafarge will spend approximately $8,000,000 over five years to implement these management practices.

Health and Environmental Effects

Discharges of stormwater runoff, including runoff from concrete manufacturing sites, can have a significant impact on water quality. As stormwater flows over a concrete manufacturing facility, it can pick up other pollutants such as debris, pesticides, petroleum products, chemicals, solvents, asphalts and acids which may also contribute to water quality problems.

Sediment-laden runoff can result in increased turbidity and decreased oxygen in receiving waters, which in turn results in loss of in-stream habitat for fish and other aquatic species. Sediment can kill fish directly, destroy spawning beds, suffocate fish eggs and bottom dwelling organisms, and block sunlight resulting in reduced growth of beneficial aquatic grasses. In addition, sediment can impact the treatment of drinking water resulting in higher treatment costs, and can result in the loss of drinking water reservoir storage capacity and decrease the navigational capacity of waterways.

Supplemental Environmental Projects (SEPs)

Lafarge will implement two SEPs. The company will execute two conservation easements to protect approximately 166 acres in Maryland and Colorado. The total appraised value of the Maryland and Colorado properties is $2,950,000.

Both properties are located in ecologically sensitive areas, and their preservation in their natural state will help protect water quality. Moreover, conservation easements will ensure that the properties are not lost to commercial or residential development in the future.

Finally, Lafarge will implement a Colorado state SEP. The company will provide $10,000 to the Western States Project, an organization that conducts environmental training for state inspectors.
