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

You must report a suspected belowground 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 operating 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

Regulated Underground Storage Tank (UST) systems are defined at 18 AAC 78.005. Releases at heating oil tanks must be reported.


Spill Reporting Placard (PDF 824K, updated November 2016) – The placard lists contact numbers for the ADEC Area Response Teams and summarize notification requirements for discharges of oil and hazardous substances.

Spill Reporting Form (PDF 389K, 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 (PDF 29K, updated 9/19/2000) – 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 (Word 284K, updated 11/23/2015) – A person in charge of a facility or operation shall maintain, and provide to 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 (PDF 44K, added 12/10/2014) – 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 insure 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 (PDF 221K, added 9/16/2014) – This form is to be used to log the collection of locational information for applicable regulated facilities and spill sites.
