Apparent problems with the modeling in the Brookglen area were discussed along with options and solutions. Talbot was willing to work with our more detailed engineering information on the B 112-02 plan as long as the information supports an abatement of losses. The next buyout application is due by end of September. They need us to confirm their candidate list taking into account the effects of BI12-02 improvements and avoiding the checkerboard effects to the community as much as possible.
