Add the following to Attachment A, Scope of Services "PHASE 8 - RAPID BENCH-SCALE MEMBRANE TESTING (RBSMT) Task 1 - Develop Protocol Black & Veatch LLP (B & V)will work with the City of Beaumont to evaluate available data and determine the best protocol for the Rapid Bench-Scale Membrane Testing (RBSMT); including determining the sample collection point, sampling schedule, Simulated Distribution Study (SDS), storage conditions, and selecting the two membrane types and pretreatment processes based on membrane manufacturers' data and the water quality parameters. This task will include a workshop meeting in Beaumont with City staff. Task 2 - Coordinate with EPA Based on the protocol developed in Phase 1, B & V will complete and submit the forms required before testing begins, including the Study Concept Form and the Study Plan. B & V will coordinate with the EPA to secure approval of the Concept and Plan. B & V will also review EPA reporting forms completed by the analytical laboratory to ensure the ICR requirements are met. Task 3 - Acquire Membrane Materials B & V will acquire the selected membrane and spacer materials after EPA has approved the Study Plan. Task 4 - Progress Meetings B & V will meet in Beaumont with the City staff before the first sampling event, at the approximate midpoint of the project, and at project completion to coordinate logistics and present results. Task 5 - Verify RBSMT Protocol The actual operation of the RBSMT will be performed by a certified analytical laboratory. B & V will verify that the test methods meet EPA's guidelines. This task will include a B & V membrane specialist working with laboratory staff at their site during a trial run of the RBSMT equipment. October 7, 1997 AMEND-1 EXHIBIT "A" Task 6 - RBSMT Testing and Analysis The ICR requires that the treatment study be conducted in four consecutive quarters for one year. The following procedures will be completed for each quarterly study: Subtask 1 - Sample Collection • Two 55-gallon containers will be shipped to the City of Beaumont for water sample collection. • City of Beaumont staff will collect water samples in the two 55-gallon containers at a point determined by the City and Black & Veatch. • Black & Veatch will coordinate sample collection with refrigerated shipment of the two 55-gallon containers to the laboratory to ensure sample integrity during transport. Subtask 2 - Treatment Study • Upon arrival at the laboratory, the sample will be analyzed for TOC and any other parameters necessary to assess sample representativeness. • All samples will be stored at 4°C. • Laboratory will conduct two rapid bench-scale membrane tests (one test with each of the two membranes) based on the ICR Manual for Bench- and Pilot- Scale Treatment Studies. Each RBSMT may run up to 10 days depending on the water quality, membrane, and design. The tests will be as follows: First Quarter Membrane 1 Run 1 Run 2 Run 3 Run 4 Recovery = Recovery = Recovery = Recovery = 70 percent 90 percent 50 percent 30 percent Membrane 2 Run 1 Run 2 Run 3 Run 4 Recovery = Recovery = Recovery = Recovery = 70 percent 90 percent 50 percent 30 percent Second Quarter Membrane 1 Run 1 Run 2 Run 3 Run 4 Recovery = Recovery = Recovery = Recovery = 70 percent 90 percent 50 percent 30 percent Membrane 2 Run 1 Run 2 Run 3 Run 4 Recovery = Recovery = Recovery = Recovery = 70 percent 90 percent 50 percent 30 percent October 7, 1997 AMEND-2 Third Quarter Membrane 1 Run 1 Run 2 Run 3 Run 4 Recovery = Recovery = Recovery = Recovery = 70 percent 90 percent 50 percent 30 percent Membrane 2 Run 1 Run 2 Run 3 Run 4 Recovery = Recovery = Recovery = Recovery = 70 percent 90 percent 50 percent 30 percent Fourth Quarter Membrane 1 Run 1 Run 2 Run 3 Run 4 Recovery = 70 Recovery = Recovery = Recovery = percent 90 percent 50 percent 30 percent Membrane 2 Run 1 Run 2 Run 3 Run 4 Recovery = Recovery = Recovery = Recovery = 70 percent 90 percent 50 percent 30 percent • Samples collected from the permeate, the concentrate, and the feed will be analyzed for the required parameters for each of the two membranes using ICR-approved analytical methods. The laboratory will perform the analyses listed below: Analysis Feed Concen- Permeate Total/ Total/ trate quarter sample Alkalinity 4 5 5 28 112 Bromide 4 5 5 28 112 Ca 4 5 5 28 112 Hardness Total 4 5 5 28 112 Hardness Turbidity 4 5 5 28 112 TDS 4 5 5 28 112 TOC 4 5 5 28 112 UV254 4 5 5 28 112 October 7, 1997 AMEND-3 Analysis Feed Concen- Permeate Total/ Total/ trate quarter sample pH 3 5 5 26 104 Temp, 3 5 5 26 104 SDS-CI 3 5 16 64 SDS-TOX 4 5 18 72 SDS-THM 4 5 18 72 SDS-HAA 4 5 18 72 Total 346 1384 Task 7 - Reports The following reports will be developed as follows: Subtask 1 - Quarterly Reports A quarterly report will be submitted to the City of Beaumont after all analyses for each RBSMT session is completed.
