The Independent Oil and Gas Association, in cooperation with the Department of Health and Human Resources (DHHR) provides this updated mapping information made available from them to WVDEP concerning changes in the Zones of Critical Concern (ZCCs), Zones of Peripheral Concern (ZPCs), and Wellhead Protection Areas (WPAs) which includes the conjunctive delineation as defined in 64 CSR 3.

This information is utilized in the assignment of “levels” to regulated ASTs. Specific changes may be found in the table below. The “level” classification previously assigned to ASTs that are located within the new coverage areas will change. The document can also be found at the following webpage:

WVDEP will incorporate these changes into the AST database and notify AST owners via email of their new AST level, as applicable. The level changes will be effective on October 15, 2020. Prior to the level changes becoming effective, you may view a map of the new coverage areas (see directions below). The map of new coverage areas provided by DHHR will be available on WVDEP’s website on or about August 28, 2020.

This information is intended to assist AST owners as they make AST management decisions. However, it is not final and considered “draft” information prior to October 15, 2020. The information is subject to change and may be incomplete. WVDEP anticipates annual updates to coverage zones will continue as water intakes are added or deleted.
