* The permittee shall submit the Well Registration Numbers, location, and well construction data to ADWR before commencing recharge activities for the associated phase.

The information will be inserted into this table at that time.

1 The permittee may provide water level data measured by either an electric sounder or pressure transducer equipment as needed as long as the permittee complies with permit conditions 4.a. and 6.d. for all water level measurements.

2 Upon commencing recharge under this permit, the monitoring frequency shall be once every two weeks until the facility has operated for a period of twelve (12) consecutive months with less than two (2) instances alert level exceedances at any of the Table 2 monitoring points. After this twelve-month period, the monitoring frequency shall be automatically reduced to monthly for all of the Table 2 monitoring points without the need for a permit modification.

3 When the permittee constructs North Plains site basins 1B and/or 2B, the permittee shall install MW-NP-4.

4 If additional monitoring is necessary, the permittee may monitor and report water level measurements from MW-NP-1. The permittee shall consult with ADWR to determine the monitoring and reporting frequencies, which will be incorporated into this table at that time.
