Reducing the Cost of Hazardous Waste Remediation by Using Land Use Restrictionsfor Risk Reduction at Air Force Closure Installations

摘要

This research reviewed 16 environmental cleanup Records of Decision (ROD) from 12different Air Force bases to determine the amount of savings possible from land-use restrictions. Land-use restriction is defined as keeping the use of the land and/or groundwater in its present form. The savings is obtained by comparing the cost of the land-use restriction alternative to the cost of the remedy selected in the ROD. A total savings of 13 percent was obtained from all 16 RODs. The 13 percent is considered a conservative estimate. The savings at individual sites ranged from zero to 92 percent. The research methodology employed also surveyed Air Force base-level environmental managers on possible cost savings measures. The 64 survey respondents ranked Realistic Risk Assessments first and Land-use Restrictions second among the five cost-savings measures ranked. The survey respondents estimated Realistic Risk Assessments as having a 26-40 percent savings potential and Land-use Restrictions as having a 16-25 percent savings potential.
