EPA provides a list of storage types and conditions for pressure and temperature in the instructions for the paper Tier II form and as dropdown menus in Tier2 Submit. Are facilities required to use the storage types and conditions that EPA provides, or can facilities provide different values?
Facilities are not limited to the values provided by EPA. The tables in the instructions and the dropdown menus in Tier2 Submit provide examples of some of the common storage types that facilities use at their site and common pressure and temperature conditions. However, facilities may provide a detailed description for the storage types and conditions at the facility if they choose. Although Tier2 Submit provides a dropdown menu or pick list, facilities have the option to provide a description not listed by selecting the field, choosing the option to "Edit Value" and typing in a description.
