Tier II Chemical Reporting in Alaska: Who Files & How

Short answer: Alaska is stricter than federal law for several chemical classes. You file through E-Plan between January 1 and March 1, and the Alaska Department of Environmental Conservation says any quantity of certain placarded hazard classes, and compressed gases at 1,000 cubic feet, must be reported — not just chemicals at 10,000 pounds. It goes to your State Emergency Response Commission (SERC), your Local Emergency Planning Committee (LEPC), and your local fire department. Alaska accepts Tier II only through E-Plan and requires a site plan with every report. The hardest part is compiling an accurate inventory with quantities — which is exactly what SDSentry ($24 per location per month) keeps current for you year-round. Here is how Tier II works in Alaska.

What Tier II is (and isn't)

Tier II is the annual chemical-inventory report required under Section 312 of the Emergency Planning and Community Right-to-Know Act (EPCRA). Its purpose is to tell fire departments and emergency planners what hazardous chemicals are stored at your facility, in what quantities, and where, so responders know what they are walking into. It is a separate obligation from OSHA Hazard Communication — the same chemicals on your shelves, but a different law and a different audience. Meeting your HazCom duties does not satisfy Tier II, and vice versa.

Who has to file in Alaska

Alaska DEC: “Several categories of chemicals have stricter reporting thresholds in Alaska than required by Federal regulation.” The thresholds DEC lists, from Alaska Statute 29.35.500(c), are:

• Any quantity of a hazardous material in the federal placarding classes Poison Gas Hazard Division 2.3 and Poisons 6.1; Explosives 1.1; Explosives 1.2 and 1.3 (excluding smokeless gunpowder, black powder and ammunition); Flammable solid Divisions 4.1, 4.2 and 4.3; or Radioactive Hazard Class 7.
• 10,000 pounds for other hazardous chemicals or materials handled in a single day.
• 500 pounds or the Threshold Planning Quantity, whichever is less, for Extremely Hazardous Substances.
• 1,000 cubic feet or more of compressed gases at standard temperature and pressure.

DEC's table of common Alaska chemicals shows what that means in practice: diesel fuel at about 1,400 gallons, gasoline at about 1,600 gallons, home heating oil at about 1,200 gallons, anhydrous ammonia and sulfuric acid (including in lead acid batteries) at 500 pounds — and chlorine at any amount. Retail gas stations with compliant underground tanks use 75,000 gallons of gasoline and 100,000 gallons of diesel.

Where Alaska facilities submit

EPCRA sends every Tier II report to three places: your State Emergency Response Commission (SERC), your Local Emergency Planning Committee (LEPC), and your local fire department.

Alaska's SERC is co-chaired by the Alaska Department of Environmental Conservation (DEC) and the Department of Military and Veterans Affairs. DEC: “The E-Plan interface is the only accepted form for Tier II reporting in Alaska. Reports will not be accepted by any other method,” and paper copies are not accepted. Once you submit, DEC says your information “will be immediately accessible” to the SERC, your LEPC, and your local fire department “if they have signed up for access.” Anchorage accepts E-Plan reports but has its own requirements, so check the Anchorage Community Right-to-Know page if you are there.

Two Alaska extras. A site plan is mandatory: “Your E-Plan submission will not be validated/accepted until you attach a site plan,” though a hand-drawn scan or annotated Google Earth image is fine. And the SERC requires shipping information for each chemical — how it arrives, how often, container size and carrier. Changes during the year, such as new chemicals, “must be reported within 30 days of their occurrence.” Start from DEC's Tier II reporting page.

State systems and instructions can change year to year, so confirm current details with Alaska DEC (tiertwo@alaska.gov) before you file.

The deadline

DEC: “The Tier II reporting period is January 1 through March 1 each year for the chemicals present at your facility during the previous calendar year.” E-Plan will not accept the new year's report before January 1.

Are there Alaska state fees?

DEC's Tier II page does not mention a filing fee, and we found none. That is an absence, not a written “no fee” statement, so confirm with DEC (tiertwo@alaska.gov).

What to have ready before you file

The report itself is mostly a structured list. What slows people down is assembling accurate underlying data. Before you start, have on hand:

• A complete chemical inventory for the location, with the product name and chemical identity for each item.
• The maximum quantity on site during the year and the average daily quantity, with units.
• Storage details — container type, pressure, temperature, and the specific location or building.
• Hazard information from each product's safety data sheet.
• Facility identifiers, emergency contacts, and (where required) latitude and longitude.

If you keep a current SDS library and a per-location inventory with quantities throughout the year, the February scramble largely disappears. See our guide on building a chemical inventory from scratch for a starting point.

How SDSentry helps

SDSentry tracks quantity and unit per item in your per-location inventory, flags items over a threshold you set, and exports an EPCRA Tier II CSV so your preparer is not rebuilding the inventory by hand each February. It keeps a current SDS on file for every product, which is where most of the hazard and storage details on the report come from. It will not submit the report for you — you still file through E-Plan — but it turns the worst part, compiling and maintaining the data, into a download. Pair it with our HazCom compliance checklist so your OSHA and EPCRA obligations stay covered at the same time.

Educational information only, not legal or compliance advice. Tier II thresholds, deadlines, submission methods, and any state fees change, and Alaska's specific process is set by the state. Verify your obligations with Alaska DEC (tiertwo@alaska.gov), and with EPA's EPCRA resources at epa.gov/epcra, before you file — and consult a qualified professional for your situation.
