How Alaska takes it

Alaska requires E-Plan, and E-Plan imports the file we build.

Alaska’s own pages name no filing fee. That is not the same as the state saying there is none, so if it matters to your budget, ring them and ask.

The file we build is the one this state works from.

The filing is due 1 March each year and covers the calendar year before it. Alaska takes the filing, but your fire department still needs its own copy from you. Alaska says the local emergency planning committee does not — so this is two recipients, not the usual three.

Before you send it — what else Alaska asks for

Alaska takes E-Plan and nothing else — not email, not paper. Filing in E-Plan reaches the state commission and your LEPC. Your fire department sees it only if it has signed up for E-Plan access, so ask it. Two more Alaska rules: attach a site plan, or E-Plan will not accept the report, and report changes within 30 days of when they happen. Anchorage has rules of its own on top. The people to ask are the Division of Spill Prevention and Response: tiertwo@alaska.gov, 907-269-3071.

Does Alaska set its own limits?

Alaska sets the threshold itself lower than the federal one. That changes the answer for a smaller facility.

Alaska’s environment department applies stricter limits to some hazard classes when you file Tier II in Alaska. Poison gases and poisons, most explosives, flammable solids and radioactive material count in any amount. A compressed gas counts from 1,000 cubic feet. Everything else uses the federal numbers. Anchorage adds rules of its own, so check its fire department page too.

The words we read

AS 29.35.500 (Alaska Statutes 2025, Title 29 Municipal Government, ch. 35 art. 8), read 2026-09-07 from akleg.gov. (a) the duty exists only “If a municipality establishes a program for the reporting of hazardous chemicals, hazardous materials, and hazardous wastes,” and such a municipality “may not (1) use a form other than the one required under this section or use a form in addition to the one required under this section; (2) require a business or government agency to submit an inventory … unless … required to do so by the Alaska State Emergency Response Commission; (3) require reporting … of a substance not listed in (c); (4) require reporting … in smaller quantities than provided under (c) … unless … approved by the commission.” (c) reportable quantities: “any quantity” of 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, and Radioactive Hazard Class 7; other hazardous chemicals or materials “handled in a single day in an amount equal to or greater than 10,000 pounds”; “extremely hazardous substances in a quantity equal to or more than 500 pounds or the threshold planning quantity, whichever is less”; and “compressed gasses equal to or more than 1,000 cubic feet at standard temperature and pressure.” (d) the first inventory is due “within 90 days after the municipality’s reporting requirements take effect or within 30 days after beginning to engage in the handling,” and annually thereafter. Alaska Department of Environmental Conservation, “Emergency Planning and Community Right-to-Know Act and State of Alaska Tier II Reporting” (dec.alaska.gov), read 2026-10-12 through the Internet Archive snapshot dated 2026-06-16 because the live page refuses our requests with HTTP 403. Under “Are there any Alaska-specific reporting requirements?” it says: “Several categories of chemicals have stricter reporting thresholds in Alaska than required by Federal regulation. The following substances and reporting thresholds are established in Alaska Statute 29.35.500(c)”, and lists the same classes. The statute’s own wording ties these numbers to municipal programmes; the department applies them to Tier II reporting in Alaska, so we follow the department — it is the stricter reading.

Where we read this

Alaska Department of Environmental Conservation, “EPCRA and State of Alaska Tier II Reporting” (dec.alaska.gov/spar/ppr/prevention-preparedness/tier-ii-reporting), read 2026-09-06 and 2026-09-11: “E-Plan is the only accepted form for Tier II reporting in Alaska, and reports will not be accepted by any other method.” EPCRA sections 311-312 “require facilities … to annually submit an inventory of those chemicals to the State Emergency Response Commission, Local Emergency Planning Committees, and fire departments with jurisdiction.” Technical assistance for state reporting comes from “the Department of Environmental Conservation’s Division of Spill Prevention and Response at 907-269-3071 or email tiertwo@alaska.gov”.E-Plan, User’s Guide, read 2026-09-07: “You can use the Import Tier2 function to import an existing Tier2 Submit export file (ZIP), Tier2 submission file (T2S), or CAMEO export file (ZIP) into your E-Plan account,” and its FAQ has a page for exactly that. So the file we build goes across instead of being retyped; you still complete the fields Alaska adds and pass E-Plan’s validation before submitting.Alaska DEC, Tier II page (dec.alaska.gov), read 2026-10-12 through the Internet Archive snapshots dated 2026-02-11 and 2026-06-16 because the live page refuses our requests with HTTP 403: “Upon successful submittal of your Tier II report through E-Plan your Tier II information will be immediately accessible to the following entities as required by regulation: Your local fire department (if they have signed up for access) Your Local Emergency Planning Committee (LEPC) The State Emergency Response Commission (SERC)”; “Changes must be reported within 30 days of their occurrence.”; “In October 2018 the Alaska SERC voted to require the submission of site maps with Tier II reports … Your E-Plan submission will not be validated/accepted until you attach a site plan.”; “Anchorage has specific reporting requirements that differ from the State requirements.”Checked 2026-09-11
