Stated Preference Summary Tables for BA.xls

Author: Abt Associates Inc.

Created: 05/02/2014

Worksheet Description

Fish Saved and HH WTP Presents fish saved and household WTP based on the SP survey.

SP Benefits Presents benefits estimates based on the survey. Note that these 

benefits estimates are not included in EPA's cost-benefit comparison for 

the final rule.

Purpose: This file summarizes percent fish saved and household (HH) willingness-to-pay (WTP) 

under the final rule and options considered based on the 316(b) stated perference (SP) survey. It 

also presents benefits estimates based on the survey. Note that these benefits estimates are not 

included EPA's cost-benefit comparison for the final rule. The tables are presented in Chapter 11 of 

the Benefits Analysis for the final rule.

a

 When calculating percent fish saved, EPA used a baseline which reflected current technology at regulated facilities 

including those facilities in CA and NY that are subject to state regulations. This differs from the rest of the benefits 

analysis, where EPA assigns these facilities baseline IM&E reductions commensurate with technologies required by the 

state regulations. This approach is consistent with the survey materials which were based on total IM&E. Fish saved 

under the elimination of baseline IM&E can be less than 100 percent because EPA does attribute IM&E reductions at 

facilities subject to state regulations to the existing facilities rule.

b

 This hypothetical scenario reflects the benefits that would be achieved if all IM&E were eliminated.

c

 The calculation of Fish Saved (%) for the Pacific survey region includes reductions in A1E losses at Hawaii facilities.

were not included in the mail survey sample.
