Tier II battery reporting under EPCRA requires facilities to submit annual inventory reports for hazardous chemicals—including lead-acid, lithium-ion, or nickel-based batteries—stored above threshold amounts (typically 10,000 lbs). Reports detail storage locations, quantities, and risks, submitted via EPA’s Tier2 Submit software by March 1. Failure to comply risks fines up to $56,460 per day. Forklift Lithium Battery Category
What triggers Tier II reporting for batteries?
Threshold quantities dictate Tier II reporting: 500 lbs for extremely hazardous substances (e.g., sulfuric acid in lead-acid) or 10,000 lbs for general hazardous chemicals. Lithium-ion batteries often trip thresholds due to electrolyte volume—a 500 kWh Li-ion pack exceeds 10,000 lbs. Pro Tip: Aggregate all battery types by chemistry—separate stacks could bypass reporting illegally.
For example, a warehouse storing 800 lead-acid forklift batteries (each 60 lbs) hits 48,000 lbs—well above 10,000 lbs. Technically, Tier II requires:

| Requirement | Details |
|---|---|
| Submission Deadline | March 1 annually |
| Reporting Tool | Tier2 Submit software |
| Data Required | Storage location, max daily amount, hazards |
But what if your facility uses multiple battery chemistries? EPA mandates summing each type separately—lithium, lead, nickel—each against their thresholds.
How are battery thresholds calculated?
Thresholds apply to hazardous components—like lithium (≥1% in Li-ion) or lead (≥0.1% in lead-acid). Multiply battery weight by hazardous substance concentration. Pro Tip: For LiFePO4, calculate lithium content as 6-7% of total cell weight. A 72V 150Ah LiFePO4 battery (150 kg) contains ~9.75 kg lithium—if stored in quantities exceeding 500 lbs (227 kg), reporting triggers.

Here’s a comparison for common batteries:
| Battery Type | Hazardous Substance | Threshold |
|---|---|---|
| Lead-Acid | Lead (35% of weight) | 10,000 lbs total |
| Li-ion (NMC) | Lithium (6%) | 500 lbs lithium |
Practically speaking, a facility with 2,500 lbs of Li-ion batteries (containing 150 lbs lithium) would breach the 500 lbs threshold. Wait—no, because the lithium itself must reach 500 lbs. Transitioning to larger formats? Monitor aggregate inventory quarterly to avoid surprises.
What’s included in a Tier II battery report?
Storage details and risk profiles form the core. Facilities must specify building/room locations, container types (e.g., steel racks for forklift batteries), and worst-case spill scenarios. Pro Tip: Use NFPA hazard codes—Li-ion gets “3” for reactivity, “2” for health. For example, a 48V lithium battery bank in a warehouse requires:
- Lat/long coordinates of storage area
- Maximum daily weight (peak inventory)
- 24/7 contact info for emergencies
But how detailed is “storage location”? EPA requires specificity like “Aisle 3, Battery Room B.” Analogous to labeling fire extinguishers—clear, immediate access for responders.

FAQs
Late submissions incur fines up to $56,460 daily. File ASAP and document corrective actions to mitigate penalties.
Do alkaline batteries require Tier II reporting?
No—EPA exempts non-hazardous types like alkaline or zinc-carbon unless containing reportable heavy metals.
Are recycled batteries included?
Yes—if stored onsite over 365 days, recycled batteries count toward thresholds. Track turnover dates rigorously.
