4 <br /> represent the most common BMPs in use by the ACWA member agencies to address <br /> traditional pollutants of concern in urban stormwater with a focus on TMDL parameters <br /> and/or associated surrogates. <br /> • Conduct a literature review to obtain results from relevant past and on-going BMP <br /> monitoring studies. For structural BMPs, the literature review should focus on those <br /> studies that are literature reviews in themselves (e.g., the EPA/ASCE International BMP <br /> database, the Center for Watershed Protection database, Water Environment Research <br /> Foundation, etc.) and should not evaluate studies of individual BMP installations. The <br /> remaining portion of the literature review for structural BMPs should be focused <br /> primarily on the most promising studies conducted in Oregon and other applicable studies <br /> in the Pacific Northwest and California. <br /> • Prepare an annotated bibliography of studies reviewed. <br /> • Prepare a prioritized summary of the gaps or deficiencies in information about pollutant <br /> <br /> . reduction effectiveness. <br /> • Conduct a survey of the ACWA stormwater program managers to identify the types of <br /> information (and the format of the final products) that would be most helpful to their <br /> programs. <br /> • Propose a database structure for organizing information about BMP effectiveness. <br /> Potential elements of the database would include the following information regarding <br /> each BMP type: effectiveness at reducing pollutants, effectiveness at achieving desired <br /> effluent quality, effectiveness at reducing discharge volumes, importance of and <br /> description of relevant physical variables, costs to implement, operate and maintain, <br /> lifecycle costs, ease of maintenance, constructability, regulatory acceptability, public <br /> perceptions, side benefits/impacts, applicability, cost of measuring effectiveness, and <br /> anecdotal comments/observations/cautions with respect to design, construction, operation <br /> or maintenance. <br /> • Attend meetings to receive comments on interim products and to obtain approval for final <br /> products. <br /> Part A Deliverables <br /> • A literature review that identifies findings from relevant and scientifically valid, <br /> applicable national studies and scientifically valid local studies regarding the <br /> effectiveness and cost of structural and nonstructural water quality BMPs. The survey <br /> will also identify data gaps and limitations. <br /> • A final scope of work for Part B of the project based on the results of Part A tasks. <br /> Part B Scope of Work <br /> • Develop the database based on the guidance tool structure proposed and approved under <br /> Part A. <br /> • Where considered appropriate by the consultant, conduct a wider ranging literature <br /> review in an attempt to address the data gaps identified in the Part A initial summary of <br /> data gaps. <br /> • Evaluate data collected from the Part A literature review and the data gap literature <br /> review. <br /> • Determine the amount of data validation that would be desirable and propose a method <br /> PAGE 4 REQUEST FOR PROPOSALS - - Stormwater BMP Effectiveness Review <br /> February, 2003 <br /> _ <br /> <br />
