As part of Tier II chemical inventory reporting, a facility must provide a brief description of the precise location of the hazardous chemical at the facility (40 CFR 370.42(i)(8)(i)). EPA regulations state that the facility may also attach a site plan with the Tier II inventory form that contains site coordinates indicated for buildings, lots, areas, etc., throughout the facility (40 CFR 370.42(i)(8)(i)(A)). Additionally, some states require facilities to submit a site plan. Is it possible to attach a site plan using Tier2 Submit?

Tier2 Submit does allow a user to attach and submit a site plan with the Tier II inventory information. However, before using Tier2 Submit to submit a site plan, the facility should check with the relevant State Emergency Response Commission (SERC), as some states have specific requirements in addition to the federal Tier II requirements and may require a different method to submit a site plan.

Users should click the Facility icon in the top left corner, then click "List all facilities in the database". From there, double click to open the desired facility. However, if a user is already on the facility page, he or she can start with the next step. Once the desired facility is open, scroll down to the Attachments section and click "Add a File". After the file is added, check the box "I have submitted a site plan".
