For groundwater withdrawals where available information indicates the area of impact for the withdrawal will be less than 12 square miles, the director may estimate, through the use of modeling techniques, the area of impact of a withdrawal for use by the applicant in developing a mitigation plan.

B. The applicant may choose to use the area of impact estimated by the department or the applicant may conduct a geophysical investigation to gather site-specific information to be used as the basis for identifying the area of impact of the withdrawal.

C. The area of impact, whether estimated or identified through an evaluation of a geophysical investigation, shall be included in the permit's mitigation plan if a plan is required by 9VAC25-610-110 D 3 g.

D. Mitigation plans for all surface water and groundwater conjunctive use system permits and supplemental drought relief permits shall address the area of impact associated with the maximum groundwater withdrawal allowed by such permits.
