 DTSC Notification Regarding Potential Risks from Vapors from the Ketema Aerospace Groundwater Contamination Plume in El Cajon

 

The California Department of Toxic Substances Control (DTSC) has issued a notification regarding the Ketema Aerospace & Eletcronics Facility: Ketema Facility Notification

 

Release reporting is required by several state and federal laws. The Hazardous Materials Division (HMD), as the local CUPA, is responsible for ensuring that persons, who are required by law or regulation to report a release, do make an accurate report in a timely manner.

 What is a reportable release of hazardous material?

There are two types of hazardous materials releases that must be reported; a threatened release and a significant release.

A threatened release is not a release. It is a condition that creates a substantial probability of harm and makes it reasonably necessary to take immediate action to prevent, reduce, or mitigate damages to persons, property, or the environment. For example:

  • A hazardous material or waste storage tank becomes unstable, and it begins to tilt off center or lean to one side. The tank is in danger of falling over and releasing its contents to the floor or ground.
  • A valve on a tank or on piping has corroded and it could fail under normal operating conditions.

A significant release is subjective. All significant releases must be reported.
Whether a release is significant depends on a variety of factors, including the following: the amount, the hazardousness of the material or waste, and/or the proximity of sensitive receptors such as schools, nursing homes, etc. See checklist below for examples of reportable and non-reportable releases.

 

 Reporting a release

After the initial immediate measures have been taken to protect human health and the environment, report the release at once to the following agencies in accordance with State and Federal law. The Department of Environmental Health collaborated with the Industrial Environmental Association and representatives from local businesses to develop this release reporting assessment tool and incident recording form to assist businesses with the requirement to immediately report significant releases of hazardous materials. The form can assist businesses in documenting why a release was not reportable. Always use the County of San Diego tool in conjunction with the CalOES Release Reporting Book

  1. Call 911 for emergency assistance. This usually results in a fire department response
  2. Call California Office of Emergency Services (Cal OES), 800-852-7550.
  3. Call the local CUPA (HMD) at 858-505-6657.
  4. If a release exceeds the federal reportable quantity (RQ), call the National Response Center (NRC), 800-424-8802.

Mandatory release reports:
A release of a reportable quantity (RQ) of a hazardous material must be reported. RQs are listed in the CERCLA “List of Lists”.  This document is maintained by the United States Environmental Protection Agency.  Another way to determine if a RQ has been exceeded is to use the Department of Energy’s online RQ calculator. NOTE: ensure that adequate and appropriate spill containment and mitigation equipment is on hand. It is advisable to periodically check all the hazardous materials stored or used at a facility. Determine the RQs and likely release reporting scenarios in advance.  This information could be included in the facility release reporting notification procedures. Flow charts or a list of questions might aid facility personnel in this task.

Determining if a release is reportable:

These sample questions can be used to determine if a release is reportable:

  • Is it a hazardous material? This can be any hazardous substance used in your business or any hazardous waste that is generated by your business.
  • Is there a threatened release?
  • Was it necessary to take immediate action to prevent, reduce, or mitigate damages to persons, property, or the environment?
  • Is there an actual significant release?
  • Is the release reportable per federal or state laws and/or regulations?
 

Examples of significant releases:

  • Hazardous material release that exceed RQ, or 
  • Result in an emergency response, or
  • Cause injury, or
  • Go offsite, or
  • Are released into the environment.
 

Examples of releases that may not need to be reported:

  • Present no health or safety hazard, or
  • Do not harm the environment, or
  • Do not enter the atmosphere, or
  • Are completely contained onsite, or 
  • Are completely recovered or removed quickly, or 
  • Do not require additional PPE to be worn. 
     

How to follow up after a release:

  • Revise the initial release report as necessary to accurately portray the situation.
  • Review and revise release response plans if they were not completely effective tools during the emergency.
