Every facility that stores hazardous chemicals above certain quantities must account for them once a year to the people who would respond in an emergency. That accounting is the Tier II report, required under Section 312 of the Emergency Planning and Community Right-to-Know Act (EPCRA). Keeping the inventory accurate all year and turning it into a state-ready submission by the March 1 deadline is exactly what chemical management software is built to do.
Why Tier II Reporting Is Hard to Get Right
What Is EPCRA Tier II Reporting?
EPCRA, also known as SARA Title III, was enacted in 1986 to give communities the right to know what hazardous chemicals are stored nearby. Under Section 312, facilities that are required to maintain a Safety Data Sheet (SDS) for a chemical under OSHA Hazard Communication must report that chemical's inventory annually when on-site quantities reach the reporting threshold.
The completed Tier II report goes to three recipients: the State Emergency Response Commission (SERC), the Local Emergency Planning Committee (LEPC), and the local fire department. Together these recipients use the data to plan for spills, fires, and releases in your community.
What Goes on a Tier II Report
A Tier II submission is more than a list of chemical names. For each reportable chemical, the report captures the same data points Ecesis tracks on every product record:
Chemical Identity and EHS Status
Each chemical is identified by name and CAS number, with a flag indicating whether it is an Extremely Hazardous Substance. EHS status changes the threshold and pulls the chemical into emergency planning under Section 302.
Physical and Health Hazard Categories
Tier II uses standardized hazard categories aligned with the GHS-based Hazard Communication Standard. Ecesis records each applicable category on the product so the report is complete and consistent:
- Physical state: solid, liquid, or gas
- Mixture or pure substance
- Health hazards: acute (immediate) and chronic (delayed)
- Physical hazards: fire, sudden release of pressure, and reactive
Quantities and Days On-Site
For each storage location the report records the maximum amount present at any time, the average daily amount over the year, and the number of days the chemical was on-site. Ecesis then totals maximum and average amounts site-wide so the facility-level figures are calculated for you, not hand-tallied across spreadsheets.
Storage Type, Conditions, and Location
Responders need to know how and where a chemical is stored. Each storage area captures the container type, storage temperature, storage pressure, and a specific facility location so first responders can find and assess the material quickly.
How Ecesis Generates Your Tier II Report
Because the chemical inventory is maintained year-round, the Tier II report is produced from data you already keep rather than reconstructed every February. The software:
- Pulls every product with constituent and area data and groups it by chemical
- Sums the maximum and average amounts across all storage areas to produce site-wide quantities
- Lets you filter to on-site products only, so chemicals no longer present are excluded
- Carries each product's physical state, hazard categories, and storage conditions onto the report automatically
- Outputs a clean report you can print to PDF for submission to the SERC, LEPC, and fire department
