Mark Your Calendar: Tier II and Air Emissions Inventories Due

Updated: Aug 28, 2023

  1. For Extremely Hazardous Substances (EHSs) designated pursuant to section 302 of Title III, the reporting threshold is 500 pounds (or 227 kg.) or the threshold planning quantity (TPQ), whichever is lower

  2. For all other hazardous chemicals for which facilities are required to have or prepare an MSDS, the minimum reporting threshold is 10,000 pounds (or 4,540 kg.)Also by March 1, 2015, you need to report hazardous chemicals that were present at your facility at any time during 2014 at levels that equaled or exceeded these thresholds. Air Emissions Inventory:   March 1 for Connecticut and Pennsylvania, April 1 for Maryland, April 15 for New York, April 30 for Delaware, May 15 for New Jersey, and various other deadlines for other states Make sure to check with your state for its filing deadline for the annual air emissions statement. While each state has slightly different requirements, most states mandate an annual inventory of air emissions to the atmosphere. The inventory must include a list of all criteria pollutants , greenhouse gases such as carbon dioxide and methane and hazardous air pollutants. Reporting data can include stack tests, Continuous Emissions Monitoring data, material balance calculations and industry-specific emission factors. Pennsylvania Residual Waste Biennial Reporting Deadline:  March 2, 2015 While most states only require the federal hazardous waste biennial report every two years, with the next report due in March 2016, Pennsylvania requires a biennial residual waste report every two years on alternating years with the hazardous waste report. Pennsylvania's next residual waste biennial report is due on March 2, 2015. Need help meeting these deadlines? We can help you not only meet the requirements but exceed them.
