Section 311-312 Hazardous Chemical Storage Reporting (Tier II)

Environmental Protection Community Right-To-Know Act (EPCRA) Section 311/312 requires facilities that have a material safety data sheet (SDS) for any hazardous chemicals stored or used in the work place above certain quantities to submit an emergency and hazardous chemical inventory form (TIER II) to the SERC, LEPC, and local fire department. The TIER II form is due annually on March 1st. Approximately 500,000 products have SDS forms. 

Iowa is switching to a new on-line tool. Check back later for more details as they become available.
