Terms and Information
High Consequence Areas (HCAs) are primarily locations that are heavily populated and have gas transmission pipelines in the vicinity. Less populated areas can also be classified as HCAs if they meet specific additional requirements, such as buildings accommodating low-mobility residents or areas where people gather for a specific number of days per year.
Non-High Consequence Areas (Non-HCAs) are primarily locations that are not heavily populated and/or do not have gas transmission lines in the vicinity.
