How is the Emergency Planning Zone (EPZ) around a critical well determined?
An emergency response zone (EPZ) is the area around a well where full-time residents and visitors to the area, such as campers and hunters, would be at risk in the event of a blowout. The size of the EPZ depends on the potential release rate of H 2 S and other specific circumstances. If you live inside an EPZ, the company will meet with you to discuss measures to be taken in an emergency and any special needs you may have, such as transportation or special health considerations.
