The first time that a subject waste is stored for more than 90 days, a notice must be submitted through the Registry. The notice must contain the following information, which includes information about the facility and information required for the registration of on-site storage for a period more than 90 days but 24 months or less, described in the ‘(1) On-site Storage for more than 90 days but 24 months or less’ section of this manual:

  • the name of the and location of the waste generation facility where the waste is stored
  • a description of the waste being stored including information about the waste consistent with the generator registration requirements. (See section 3.1.2 Waste identification for more information)
  • the reason for storing the waste
  • the anticipated manner of disposal of the stored waste
  • an estimate of the amount of waste being stored or expected to be stored
  • the manner in which the waste is stored
  • the date upon which the generator began storing the subject waste
  • whether or not the amount of waste to be stored will increase over time and if so, the expected accumulation rate and maximum amount to be stored

A notice that has been submitted through the Registry must be updated if any of the information has changed within five (5) business days after the change.

The 90-day storage period begins as soon as a subject waste is first stored at a waste generation facility. The 90-day storage period does not start when a container used to store the waste is full and ready to be shipped off-site for disposal. For waste streams that have a small quantity exemption associated with their primary characteristic, the waste is first considered to be stored when an amount equal to or greater than the SQE amount has been accumulated in a container or other means of storage. In the case of wastes for which there is no small quantity exemption, the 90-day period begins as soon as any amount of the waste is accumulated in a container or other means of storage. A brief discussion on when a waste is generated and becomes a subject waste is included in the Determining when waste is generated section.
