Abstract

This report summarizes the characteristics of the facilities that responded, and gives nationwide trends in residual management practices. The estimates, taken nationwide, were determined from a regression analysis of the respondent data in terms of residual quantity in wet tons by refinery capacity in barrels per stream day (bsd).
