McDOWELL COUNTY HAZARDOUS MATERIALS EMERGENCY PLAN

APPENDIX 9 TO HMEP

LIST OF EXTREMELY HAZARDOUS SUBSTANCES

 

 

The following list of “extremely hazardous substances” includes the names, Chemical Abstract Number (CAS #), Reportable Quantities (RQ), and Threshold Planning Quantities (TPQ) for each substance.

 

Threshold Planning Quantity – If a business stores, uses, or produces more than the “Threshold Planning Quantity” of an extremely hazardous substance at any time, they must comply with SARA Title III emergency planning and reporting requirements. For many of the substances listed below, two (2) numbers are entered under “Threshold Planning Quantity.” If a business stores, uses, or produces these substances in powdered form, and the substance meets certain other criteria that are described in federal regulations, the lower Threshold Planning Quantity applies. If not, the higher Threshold Planning Quantity applies.

 

Reportable Quantity – When a spill or release of an extremely hazardous substance exceeds the “Reportable Quantity” for that substance, the business or person that spilled or released the substance must report the release to the federal government.

 

Source: The current version of this list is codified at 40 CFR. Part 355, Appendix A. This version was included in the 1997 edition of the CFR.
