Blue print for building a risk assessment
Federal and stet regulations require the operator of a miscellaneous waste treatment unit to demonstrate compliance with environmental performance standard. A sample risk assessment is demonstrated as a means of showing compliance for such a treatment unit. A new Open Burning and Open Detonation (OB/OD) facility for explosive wastes at LLNL experimental site is used. Simplified, the process of performing a risk assessment consists of characterization of the treatment operation and estimation of emission rates; evaluation of the emission dispersion to estimate acute exposure; and evaluation of human and environmental risks. Each step may require the environmental analysts to perform detained date gathering, modeling and calculations, and to negotiate with facility operations personnel and regulatory representatives. The Risk Assessment Protocol, which explains the assumptions, model selection and inputs, and data selection, must ultimately withstand the rigors of regulatory review and public scrutiny.s
