This analysis, submitted in support of proposed effluent limitations guidelines and standards for the centralized waste treatment (CWT) industry, investigates the cost-effectiveness of 24 regulatory options, representing all possible combinations of nine proposed control options for three subcategories of CWT operations. Chapter 2 of this report discusses the methods used for this cost-effectiveness analysis. Chapter 2 also includes a discussion of the required differences for estimating pollutant removals from direct-discharging CWT facilities as opposed to indirect-discharges (facilities whose effluent receives treatment at a publicly owned treatment works (POTW) before it is discharged to surfaces waters). In addition, Chapter 2 describes how compliance costs were annualized, how two different cost-effectiveness values were calculated, and how they can be used to compare the merits of each regulatory option. Chapter 3 presents the findings of this analysis and identifies a subset of the 30 regulatory options that are demonstrably more costly and less effective than other options. Chapter 4 compares the remaining most efficient options to other promulgated rules.
