Sec. 10. (a) The department shall review Phase I and Phase II submittals based on the following criteria:

1. (1) WHPA delineation, including the following:

   1. (A) The completeness and accuracy of the data used to determine the hydrogeologic conceptualization as required in section 7 of this rule.
   2. (B) The information provided in the submittal demonstrates that the chosen delineation method properly accounts for site specific hydrogeology.

2. (2) Potential sources of contamination inventory, including the following:

   1. (A) The completeness of the specific data supplied regarding each facility, site, practice, and activity, including the following:

      1. (i) The inventory, identification, and location of all potential sources of contamination according to the data requirements of section 8(3) of this rule.
      2. (ii) Identification of all potential sources of contamination in the WHPA on a map that includes the boundaries of the time of travel.
      3. (iii) Characterization of the potential sources of contamination as specified in section 8(3)(C) of this rule is sufficient to develop a management plan as prescribed by section 8(4)(A) and 8(4)(B) of this rule.
   2. (B) The department shall evaluate Phase II based on the completeness of the update to adequately characterize the status of all potential sources of contamination identified and inventoried under Phase I, and any new potential sources of contamination that have located within the WHPA.
   3. (C) The department shall evaluate the updates made to the potential sources of contamination inventory every five (5) years, as required by section 9(2) of this rule, for completeness with respect to the status of all potential sources of contamination identified in the Phase I and Phase II submittals.

3. (3) Management plan including the following:

   1. (A) The Phase I management plan will be considered effective when all management plans and submittal requirements of section 8(4)(A) and 8(4)(B) of this rule and subdivision (1) have been met. The management plan must consider the following:

      1. (i) Site-specific hydrogeology.
      2. (ii) Land use.
      3. (iii) Conditions of potential sources of contamination.
   2. (B) The department will approve Phase II, results of implementation of Phase I, upon finding that the management plan has been implemented as proposed under section 8(4)(B) of this rule.

(b) Under Phase I, the department may require the use of a different delineation method. Under both Phase I and Phase II, the department may require submittal of additional data to support information provided as part of the WHPP.

(c) For a CPWSS using the fixed radius method to delineate a WHPA, the department may require the use of a different delineation method if the CPWSS fails to maintain the qualification for use of the fixed radius method as outlined in section 5(d) of this rule.
