How does a facility report batteries for Tier II? | US EPA
A facility has few lead-acid batteries (non-consumer type) on site. How does the facility report these batteries on the Tier II form? The facility must first determine if there are any hazardous chemicals or extremely hazardous substances (EHSs) in the batteries. Most batteries contain sulfuric acid, an EHS, and then some non-EHSs.
