EPCRA §312AK

Alaska Tier II reporting: how and where to file

Alaska takes Tier II through E-Plan only: no other method and no paper copy. Reports are filed from January 1 through March 1 each year, for the chemicals present at the facility during the previous calendar year.

From Alaska Department of Environmental Conservation (DEC), co-chair of the Alaska SERC with the Department of Military and Veterans Affairs, read on the state's own page · October 28, 2026

What Alaska asks for

Each point is followed by the words of the state's own page.

How to file

Alaska takes Tier II through E-Plan only: no other method and no paper copy.

“The E-Plan interface is the only accepted form for Tier II reporting in Alaska. Reports will not be accepted by any other method.” source
“No. Paper copies will not be accepted.” source

Deadline

Reports are filed from January 1 through March 1 each year, for the chemicals present at the facility during the previous calendar year.

“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.” source

State thresholds

Alaska sets stricter thresholds than the federal rule for some materials, under Alaska Statute 29.35.500(c): any quantity of poison gas (Division 2.3) and poisons (6.1), explosives 1.1, explosives 1.2 and 1.3 (smokeless powder, black powder and ammunition excluded), flammable solids (Divisions 4.1, 4.2 and 4.3) and radioactive material (Class 7); extremely hazardous substances at 500 pounds or the threshold planning quantity, whichever is less; compressed gases at 1,000 cubic feet or more at standard temperature and pressure.

“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):” source
“Poison Gas Hazard Division No. 2.3 and Poisons 6.1;” source
“Explosives 1.1;” source
“Explosives 1.2 and 1.3, excluding smokeless gunpowder, black powder, and ammunition;” source
“Flammable solid Divisions 4.1, 4.2, and 4.3; or” source
“Radioactive Hazard Class 7;” source
“extremely hazardous substances in a quantity equal to or more than 500 pounds or the threshold planning quantity, whichever is less; and” source
“compressed gasses equal to or more than 1,000 cubic feet at standard temperature and pressure” source

Who gets the report

A report filed in E-Plan is open at once to the SERC, the LEPC and the local fire department, if the fire department has signed up for access.

“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:” source
“Your local fire department (if they have signed up for access)” source

State-specific rule

A site plan must be attached: E-Plan does not validate the report without one. Scans of hand-drawn maps or aerial photos with a legend showing where the chemicals are kept are accepted.

“Your E-Plan submission will not be validated/accepted until you attach a site plan.” source
“we will accept scans of hand drawn maps, Google Earth snapshots with a legend describing where chemicals are located, and other clear representations of the locations of chemicals at your facility.” source

State-specific rule

The report asks how each chemical arrives at the facility: shipping mode and frequency, among other details.

“On October 25, 2019, the Alaska SERC voted to require information about how chemicals arrive at facilities on Tier II reports, including shipping mode and frequency, among other details.” source

State-specific rule

Changes during the year (a new chemical, a quantity above the threshold planning quantity, a new facility emergency coordinator) are reported within 30 days.

“Changes must be reported within 30 days of their occurrence.” source

State-specific rule

Anchorage takes E-Plan reports but has reporting requirements of its own; check the Anchorage community right-to-know page.

“Yes. However, Anchorage has specific reporting requirements that differ from the State requirements.” source

The federal rule underneath

EPCRA section 312 applies to a facility that the OSHA HazCom Standard requires to keep an SDS for a hazardous chemical present at any one time at or above 10,000 lb, or at or above 500 lb or its threshold planning quantity, whichever is lower, for an extremely hazardous substance (40 CFR 370.10(a)). The 10,000 lb figure is the general case: at a retail gas station the thresholds are 75,000 gallons of gasoline and 100,000 gallons of diesel fuel (all grades combined), and they apply only to fuel in tanks entirely underground that met every applicable underground storage tank requirement at all times during the preceding calendar year (40 CFR 370.10(a)(2)(ii) and (iii)); otherwise the general threshold applies. The report covers the previous calendar year and is due March 1 (40 CFR 370.45). Below every threshold, a request still has to be answered: when your LEPC, SERC or fire department asks for Tier II information, the threshold is zero and the information is due within 30 days (40 CFR 370.10(b), 370.45(b)). Where Alaska's rules above are stricter, they apply on top.

The full federal picture, Tier I versus Tier II, counting and penalties, is on the EPCRA Tier II hub. The list that feeds it is the chemical inventory.

HazComFast keeps each jobsite's chemical quantities next to its safety data sheets and exports the Tier II data as an Excel workbook, a CSV file and a PDF summary.

Alaska Tier II FAQ

How do I file Tier II in Alaska?

Alaska takes Tier II through E-Plan only: no other method and no paper copy.

When is Tier II due in Alaska?

Reports are filed from January 1 through March 1 each year, for the chemicals present at the facility during the previous calendar year.

Does Alaska use the federal Tier II thresholds?

Alaska sets stricter thresholds than the federal rule for some materials, under Alaska Statute 29.35.500(c): any quantity of poison gas (Division 2.3) and poisons (6.1), explosives 1.1, explosives 1.2 and 1.3 (smokeless powder, black powder and ammunition excluded), flammable solids (Divisions 4.1, 4.2 and 4.3) and radioactive material (Class 7); extremely hazardous substances at 500 pounds or the threshold planning quantity, whichever is less; compressed gases at 1,000 cubic feet or more at standard temperature and pressure.

Who gets the Tier II report in Alaska?

A report filed in E-Plan is open at once to the SERC, the LEPC and the local fire department, if the fire department has signed up for access. The federal rule is that the report reaches the LEPC, the SERC and the fire department with jurisdiction (42 U.S.C. 11022(a)(1)); in a state that takes the report in one system and passes it on, that system can meet the rule, and the state's own steps above say which applies.

Keep the chemical list behind your Tier II report current

Tier II is an EPCRA filing to your state and local agencies, not an OSHA citation. The same chemical inventory feeds your SDS binder and the report, so keep it in one place.
