PHASE III - DETAILED REVIEW /TECHNICAL VERIFICATION
The purpose of this phase, conducted by EPA Regional Office staff, is to:
* Verify the boundaries of the aquifer and the aquifer
* Verify that the aquifer is the sole or principal source of drinking water for the defined aquifer service area;
* Verify or modify, as appropriate, the boundaries of the following areas, based on information contained in the petition:
-- Designated area, including the
-- Project review area, including streamflow source area(s), as appropriate.
* Call for, and incorporate into the process, public comments
regarding the designation; and
* Make recommendation to the Regional Administrator regarding designation of the aquifer.
5.2. Technical Review
During the technical review process, the EPA reviewer may determine that technical data are insufficient to compete technical verification. If this is the case, EPA should inform the petitioner that additional technical data are needed. The petitioner should collect the additional information and supply it to EPA, ideally prior to the public hearing. In most cases the public hearing should be held even if the additional information is not available prior to the hearing.
5.3. Public Participation
EPA should hold a public hearing if there is substantive interest and should accept written comments regarding the potential designation. The public comment period may yield new information about the aquifer. The public hearing may be canceled if there is a lack of sufficient public interest. However, in all cases, EPA should consider all written comments it receives during the comment period.
EPA staff should make a recommendation for petition approval or denial to the Regional Administrator, based on the review of the petition and public comments.
