Current as of April 2008
Creosote is a wood preservative used for commercial purposes only; it has no registered residential uses. Creosote is obtained from high temperature distillation of coal tar (itself a mixture of hundreds of organic substances), and over 100 components in creosote have been identified. It is used as a fungicide, insecticide, miticide, and sporicide to protect wood and is applied by pressure methods to wood products, primarily utility poles and railroad ties.
EPA is reassessing creosote as part of its reregistration program for older pesticides. The Reregistration Eligibility Decision (RED) for creosote is scheduled for September 30, 2008. Federal law directs EPA to periodically reevaluate older pesticides to ensure that they continue to meet current safety standards. We have updated this fact sheet to reflect recent changes in the status of the registration for creosote.

- The preliminary risk assessment for creosote is a cooperative re-evaluation between the US EPA and Health Canada's Pest Management Regulatory Agency (PMRA) under NAFTA, with both countries contributing to the study review and peer review process. Exposure data used in the preliminary risk assessment were collected from both US and Canadian wood-treatment facilities.
