The document discusses the NYCDEP Right-To-Know program which was created to help communities plan for emergencies involving hazardous substances and increase public knowledge of toxic chemicals. It mandates that NYC businesses share information on potentially hazardous materials used on-site. Businesses that use substances above the threshold reporting quantity must file a Facility Inventory Form annually by March 1st along with applicable fees. The NYCDEP conducts inspections and can issue fines for incorrect or incomplete filings to enforce these reporting requirements.
