The Division and Tri-State have worked extensively <br />together under TR -118 to ensure the RCE associated with Exhibit 13C is current and con-ect. TR - <br />118 will be approved prior to this renewal package being approved; therefore, it is Tri -States <br />believes that the RCE from TR -118 should replace the Division's RCE calculated for the permit <br />renewal application. <br />16.
