Title: Development of the table of initial isolation and protective action distances for the 2000 Emergency Response Guidebook.

Abstract

This report provides technical documentation for values in the Table of Initial Isolation and Protective Action Distances (PADs) in the ''2000 Emergency Response Guidebook'' (2000ERG). The objective for choosing the PADs specified in the 2000ERG was to balance the need to adequately protect the public from exposure to potentially harmful substances against the risks and expenses that could result from overreacting to a spill. To quantify this balance, a statistical approach was adopted, whereby the best available information was used to conduct an accident scenario analysis and develop a set of up to 100,000 hypothetical incidents. The set accounted for differences in the types of containers, types of incidents, severities of accidents (i.e., amounts released), locations, times of day, times of year, and meteorological conditions involved. Each scenario was analyzed by using detailed emission rate and atmospheric dispersion models to calculate the downwind chemical concentrations. The safe distance for each incident, defined as the distance downwind from the source at which the chemical concentration falls below the health criteria, was determined. The health criteria used were the American Industrial Hygiene Association's Emergency Response Planning Guideline Level 2 (ERPG-2) or equivalent criteria. The statistical sample of safe distance values for allmore » incidents considered in the analysis was separated into four categories: small spill/daytime release, small spill/nighttime release, large spill/daytime release; and large spill/nighttime release. The 90-percentile safe distance values for each of these groups became the PADs that appear in the 2000ERG table.« less
