B. What is the Texas OptimizaHon Program? The state of Texaz hu a public water rystems participarion recogudon pro,am. The program administrated through the Texas Natural Resource Conservarion Commission is called the Texas Optimization Program or TOPs. This program is completely voluntary and is a way that the state of Texu can recognize plants that meet very demanding performance criteria The program formally commenced on July 1, 1997. Plants that participated in the charter yeaz of the program and achieved the recogrlirion criteria continuously since July would be eligible to receive the first recogurion awazd in eazly 1998. To date, two faciliries in the state of Texas have been recognized by the Texas Natural Resource Conservation Commission to have met these requirements. They are Brown Counry Water Improvement Dish-ict #1 and the City of Greenville, Texas. The recognition program operates on 18-month cycles. By the end of the first cycle, participants must achieve three objectives. Specifically, the plant must: 1. Install an on-line turbidity meter on the dischazge line from each filter. 2. Meet the recogution criteria at least three out of every six months. 3. Receive at least one optimization arvazd~i.e., have met the recognition criteria for at least one consecutive sis month period. Participants who have not achieved the first objective by the end of the first cycle, will be required to withdraw from the program until the turbidimeters have been installed. Participants who have met the first, but not both of the other two objectives, must either withdraw from the program or agree to have an independent parry conduct a comprehensive performance evaluation (CPE) at the plant by the end of the 241 month. Participants who tal:e active steps to address the performance Iimitarions (limiting factors that were idenrified during the CPE) can remain in the recognition program for a second 18 month cycle. However, participants who do not meet the three objec[ives during the second 18 month cycle must withdraNv from the recognirion pro,o,ram for at least 12 months. As soon as the plant meeu the recogrtition criteria for six consecutive months, participants will be eligible for the oprimization awazd and the 18 month cycle begins again. Since an award can be eamed each six month, a treatment plant can eam rivo awazds each yeaz if it meets the performance goals continuously. Figure 2 is a flow chart that depicts the Texas Oprimization Recognition Program milestones and requirements. The Texas Oprimization Program recognition critaria is based on performance of four treatrnent processes: 1. Sedimentation basins/clarifiers 2. Filters (excluding the post-bac4.-vash recovery period) 3. Filters (post-bact.tivash recovery period) 4. Finished water. The performance goals for each of these processes is given in Table 1. The Texas Optimization Program recognition requires the fotlowing turbidity monitoring locations: 1. Raw water entering the plant 2. Settled water at the end of the buin 3. Filtered water at the effluent of each filter 4. Finished water entering or teaving the clearwell. •
