Risk Assessment

Risk is broadly defined as the likelihood that a harmful consequence will occur as the result of an action or condition. It involves the combined evaluation of hazards and exposure.

The Environmental Protection Agencies could require the development of a risk study when there is evidence of significant pollution on a certain site. The risk assessment represents the analysis of the probability and severity of the main components of an environmental impact.

Risk Assessment - Regulations

The following regulations in force concerning environmental protection must be taken into account when preparing a Risk Assessment Study:

  • Government Emergency Ordinance no. 195/2005 concerning environmental protection, approved by Law no. 265/2006 with its subsequent modifications and completions;
  • Law no. 74/2019 concerning the management of potentially contaminated and contaminated sites;
  • Ministry Order no. 184/1997 approving the Procedure for elaborating environmental assessments;
  • Ministry Order no. 756/1997 concerning environmental pollution assessment.

The A.4, A.4.1 and A.4.2 annexes to Ministry Order no. 184/1997 stipulate the requirements that a risk study shall meet.

According to Ministry Order no. 184/1997 approving the Procedure for elaborating environmental assessments, the risk assessment is defined as "an analysis of the probability and severity of main components of an environmental assessment”.

Risk Assessment with Audoteco GES

In AUDITECO GES’s approach, the risk assessment has two components: the risk assessment (including identification of risks, the extent of potential negative effects and the probability of a dangerous manifestation) and the risk quantification (including risk prioritisation and effects on human health and/or the environment).

There are several types of risk assessment, as follows:

  • Health assessments;
  • Ecological assessments.

The stages of performing an environmental risk assessment include: hazard identification and problem formulation, analysis and risk characterization.

The risk assessment factors refer to the source-means-receiver triad and are the following:

  • Danger/Source (pollutants, toxicity, particular effects);
  • Means of action (the way from source to target);
  • Target/receiver (affected site that should be considered).

The following specific elements must be taken into account when a Risk Assessment Study is developed:

  • chemical risk;
  • carcinogenic risk;
  • epidemiological risk;
  • nuclear contamination risk;
  • a risk of natural phenomena occurrence.

As a result of a Risk Assessment Study, it is possible to identify and prioritize the risk that are unacceptably high. In such cases, whenever possible, site-specific measures for remediation or continuous monitoring should be proposed, in order to decrease to acceptable or tolerable levels any risk posed by one or several contaminants to human health and/or to the environment. A Risk Assessment Study should propose technically and economically feasible measures, without dismissing the main aim of the study.
