The Leopold matrix is a qualitative environmental impact assessment method developed in 1971 by Luna Leopold and collaborators for the USGS. [1] It is used to identify and assign numerical weightings to potential environmental impacts of proposed projects on the environment. [1]
Ecological assessment (EA) implies the monitoring of ecological resources, to discover the current and changing conditions. EAs are required components of most hazardous waste site investigations. Such assessments, in conjunction with contamination and human health risk assessments, help to evaluate the environmental hazards posed by ...
Risk assessment determines possible mishaps, their likelihood and consequences, and the tolerances for such events. [1] [2] The results of this process may be expressed in a quantitative or qualitative fashion. Risk assessment is an inherent part of a broader risk management strategy to help reduce any potential risk-related consequences. [1] [3]
The Canadian Environmental Assessment Act 2012 (CEAA 2012) [27] "and its regulations establish the legislative basis for the federal practice of environmental assessment in most regions of Canada." [28] [29] [30] CEAA 2012 came into force July 6, 2012 and replaces the former Canadian Environmental Assessment Act (1995). EA is defined as a ...
LOPA is a risk assessment undertaken on a 'one cause–one consequence' pair. The steps of a LOPA risk assessment are: [4] Identify the consequences, using a risk matrix; Define the risk tolerance criteria (RTC), based on the tolerable/intolerable regions on the risk matrix; Define the relevant accident scenario, e.g. mechanical or human failure
Contaminated land risk assessment [14] Engineered systems for drinking water treatment [15] Computing soil screening levels [16] Human health and ecological risk analysis by the U.S. EPA of PCB contamination at the Housatonic River Superfund site [17] [18] Environmental assessment for the Calcasieu Estuary Superfund site [19]
Environmental Assessment (EA): The proposal is analyzed in addition to the local environment with the aim to reduce the negative impacts of the development on the area. [ 5 ] Finding of No Significant Impact (FONSI): Occurs when no significant impacts are identified in an EA.
The four-step risk assessment process. Environmental hazard identification is the first step in environmental risk assessment, which is the process of assessing the likelihood, or risk, of adverse effects resulting from a given environmental stressor. [6]
