Large quantity consolidation
Hazardous secondary materials
Episodic generation is a planned or unplanned waste event that would normally bump your generator status to a larger category. Only medium and small quantity generators can choose to use this rule. You may notify us of one episodic event in a calendar year (Jan. 1–Dec. 31).
Planned episodic event
If you intend to have an episodic event, you must notify us first:
We recommend that you submit your notification a minimum of 60 days prior to the planned event proposed start date.
If we receive your form less than 30 calendar days before the proposed start date, we will change your start date to meet the minimum 30 calendar day requirement.
Unplanned episodic event
Unexpected waste generation events require immediate notification:
- Within 72 hours of the event, notify your regional HWTR office by email or fax.
- Within 30 days of the event, fill out the addendum and mail it with your pre-printed Site ID form.
Second episodic event in the same calendar year
You must petition your regional office and wait for our approval before managing your dangerous waste as episodic.
