Abstract
Environmental risk assessment (ERA) is predominantly a scientific activity
and involves a critical review of available data for the purpose of identifying and
possibly quantifying the risks associated with a potential threat. Risk management (RM)
is performed to consider the need to impose measures to control or manage the risk. The
working methodology presented in this paper was done based on several research studies
for the environmental risk assessment for soil pollution with hidrocarbures from
accidental crude oil spills. The qualitative and quantitative assessment of the
environmental risk for industrial sites for drilling, gas oil separation it is complex and
require several data. For these reasons a environmental risk calculation methodology for
soil is presented which is structured in modules and steps. Environment risk assessment
of pollution with hydrocarbons from crude oil comprises five interrelated modules:
hazard identification, hazard assessment, risk estimation by the award of „grades” for the
frequency and severity of consequences environmental risk assessment based on risk
criteria (ALARP) and environmental risk management. The modules required data:
technical data for the equipment in the upstream industrial activities, extraction and gasoil
separation, physico-chemical analysis for the soil contaminants, soil properties that
may influence the severity and consequences of the default risk, charts, mathematical
equations and matrix assessment of environmental risk intensity. In the methodology are
established the steps needed to calculate the alert threshold and intervention and
additional studies needed (geotechnical study, pedological and chemical study).
