Exhibit 1 : Recommended Reported Data and Relevance in Reaching

FUNDAMENTALS OF VOLUME REDUCTION . The purpose of this technical memorandum is to recommend ways to interpret and evaluate hydrologic data obtained from monitoring studies to quantify the performance of these systems, both absolutely and in comparison to other systems. This memorandum first discusses the fundamental questions that may possibly be answered through analysis and interpretation of volumetric data. This discussion considers both site level studies and practice level studies. Methods of interpreting and evaluating hydrologic data are introduced and discussed, and best practices in data interpretation are suggested. Finally this memo discusses the extrapolation of monitoring data to long term results and the comparison of volumetric performance between different types and scales of practices.
