    2. (2)Indicate whether the substance is an EHS.
    3. (3)Provide an estimate of the quantity of any such substance that was released into the environment.

    8. (8)The name and telephone number of the individual (or individuals) to be contacted for further information.
  2. (b)Written follow-up emergency notification. Except for releases that occur during transportation or from storage incident to transportation, you must provide a written follow-up emergency notice (or notices, as more information becomes available), as soon as practicable after the release. In the written follow-up emergency notice, you must provide and update the information required in the immediate notification and include additional information with respect to all of the following:
    1. (1)Actions taken to respond and contain the release.
    2. (2)Any known or anticipated acute or chronic health risks associated with the release.
    3. (3)Where appropriate, advice regarding medical attention necessary for exposed individuals.
  3. (c)You are not required to submit a written follow-up notification for a release that occurred during transportation or from storage incident to transportation. See § 355.42(b) for requirements for reporting such releases.
