Report a Spill

Alaska state law requires all oil and hazardous substance releases to be reported to the Department of Environmental Conservation. For federal reporting requirements, see the National Response Center website. 

Notification Requirements

Hazardous Substance Releases

Any release of a hazardous substance must be reported as soon as the person has knowledge of the discharge.

Oil/Petroleum Releases

To Water:

Any release of oil to water must be reported as soon as the person has knowledge of the discharge.

To Land:

Any release of oil in excess of 55 gallons must be reported as soon as the person has knowledge of the discharge. Any release of oil in excess of 10 gallons but less than 55 gallons must be reported within 48 hours after the person has knowledge of the discharge. A person in charge of a facility or operation shall maintain, and provide to the Department on a monthly basis, a written record of discharge of oil from 1 to 10 gallons.

To Impermeable Secondary Containment Areas:

Any release of oil in excess of 55 gallons must be reported within 48 hours after the person has knowledge of the discharge.

Additional Reporting Requirements for Regulated Underground Storage Tank (UST) Facilities**

You must report a suspected below ground release from a UST system, in any amount, within 24 hours (18 AAC 78.220(c)).

If your release detection system indicates a leak may have occurred, including two months of invalid or inconclusive results, then you must report it to the UST Unit. If you observe unusual operation conditions, sudden loss, erratic dispensing (slow flow/no flow) or discharge to soil or water, report to the UST Unit: 907-269-3055 or 907-269-7679.

Placards and Forms

Spill Reporting Placard updated October 2022

The placard lists contact numbers and online reporting to the ADEC Response Teams and summarizes notification requirements for discharges of oil and hazardous substances.

Spill Reporting Form updated 6/16/2014

This optional form can be faxed to the appropriate DEC office following telephone notification of a discharge. See the How To Report section near the top of this page for fax numbers. See Form Instructions.

Oil and Hazardous Materials Incident Final Report updated August 2018

This report is required by State regulation 18 AAC 75.300(e). It is due within 15 days of cleanup completion or, if no cleanup occurs, within 15 days of the discharge. 

Monthly Spill Log updated 1/18/2024

A person in charge of a facility or operation shall maintain, and provide the Department on a monthly basis, a written record of any discharges of oil from 1 to 10 gallons to land.

Transport, Treatment & Disposal Approval Form for Contaminated Media

Complete and submit this form to the ADEC Prevention Preparedness and Response Program whenever contaminated soil from a spill site is transported offsite for treatment (e.g., thermal desorption or bioremediation) or disposal. The form must be submitted for ADEC approval prior to transport of the soil from the incident site. Contaminated soil shall be transported as a covered load in compliance with 18 AAC 60.015.

Note: Bonded treatment facilities are allowed to co-mingle contaminated soil for treatment under their approved facility operations plan. Post-treatment soil samples are collected and analyzed at regular intervals to ensure that the contaminants are successfully treated. Because the post-treatment analytical results for co-mingled soils are provided directly to ADEC, the Responsible Party does not have to provide a separate copy of the post-treatment analytical results as indicated in the form.

Facility Location Data Sheet updated August 2018

This form is to be used to log the collection of locational information for applicable regulated facilities and spill sites. 

Alaska Vessel of Concern Reporting Form

Fill out the form with as much detail as possible, if sections are unknown write unknown. Submit the completed form to Alaska Department of Natural Resources – Division of Mining, Land, and Water – Statewide Abatement of Impaired Land Section, along with copies of photos if possible.
