 What is the HMBP? What is this information used for?

The HMBP contains detailed information on the storage of hazardous materials at regulated facilities.. The purpose of the HMBP is to prevent or minimize damage to public health, safety, and the environment, from a release or threatened release of a hazardous material. The HMBP also provides emergency response personnel with adequate information to help them better prepare and respond to chemical-related incidents at regulated facilities.

 Who is required to prepare an HMBP?

Businesses that handle hazardous materials (including hazardous waste) or extremely hazardous substances at reportable quantities are required to prepare and electronically submit an HMBP in CERS. The reportable quantities are equal to or greater than:

  • 500 pounds of a solid 55 gallons of a liquid
  • 200 cubic feet of a compressed gas
  • A hazardous compressed gas in any amount (highly toxic with a Threshold Limit Value of ≤ 10 parts per million)
  • Extremely hazardous substances above the threshold planning quantities (TPQs)

The HMBP will also serve to better prepare emergency response personnel for handling emergencies which could occur at your facility. The section below contains the necessary information for the creation of a useful HMBP for your facility which will be uploaded into CERS. When completed, your HMBPwill become a valuable tool, aiding you and your employees to manage emergencies at your facility.
