Release Reporting

A surface spill or overfill of a regulated substance is considered a confirmed release when: 1) any spill or overfill quantity is not cleaned up within 24 hours, or 2) a spill or overfill quantity is greater than 25 gallons.

Emergency Response

Upon discovery of a regulated substance on the ground or in surface water, or if a regulated substance has the potential to create a fire, explosion or acute health hazard, emergency response action shall be initiated immediately.

 

Site Characterization Report

If the released product has come into contact with surficial soil, surface water, groundwater, a stormwater collection system that discharges to surface water, or a sensitive environment, the owner/operator is required to conduct a site characterization in accordance with this guidance.
