You must report the inventory information for quantities of hazardous chemicals that were housed at your facility at any time during the reporting year that are greater than or equal to the threshold.
All states require Tier II submission, and it is mandatory for all facilities. All substances and chemicals that require an SDS must be recorded. Do not be selective. Record all the chemicals, that way you will have a full inventory list when you start generating your report.
Once you have the full list of your chemicals, consult the Tier II chemical list for which ones must be reported. Of these chemicals, the aspects that should be listed in a Tier II report are listed below:
- Physical and Health Hazards of each reportable chemical (all applicable)
- Maximum Amount on Site (in pounds)
- Average Daily Amount on Site (in pounds)
- The number of days chemical/mixture was present on-site (i.e., 365 days)
- Storage Types, Conditions, and Locations
You must describe the specific location of the chemical to help emergency responders to access it quickly and clearly show the building or room in which it is stored. It is helpful to provide a comprehensive site map for the chemical(s). If you would like to claim any confidential locations, you must submit your confidential location information with your Tier II report if available.
In Virginia, there are additional Tier II chemical inventory reporting requirements beyond just the annual report:
- Initial Notification: Facilities must submit a notification within 90 days after they first exceed reporting thresholds for any hazardous chemicals on site. The thresholds for this notification are the same as the Tier II thresholds.
- Emergency Planning Notification: Facilities must submit a notification within 60 days after they bring an Extremely Hazardous Substance on-site in a quantity that exceeds its Threshold Planning Quantity.
