Our communities have the right to know when they are at risk of exposure to dangerous substances from accidental releases such as, but not limited to, chlorine, ammonia, hydrochloric acid, and sulfur dioxide. The US Environmental Protection Agency (EPA) agrees. In 1986 EPA created the Emergency Planning and Community Right-to-Know Act (EPCRA) to help communities plan for just such emergencies. EPCRA requires that federal, state, and local governments, Indian tribes, and industries be prepared for hazardous chemical emergencies. It also requires facilities to follow all recordkeeping requirements and report the storage, use, and release of hazardous chemicals to federal, state, and local governments.
