title: Primer for evaluating ecological risk at petroleum release sites.
abstract: Increasingly, risk-based approaches are being used to guide decision making at sites such as service stations and petroleum product terminals, where petroleum products have been inadvertently released to the soil. For example, the API Decision Support System software, DSS, evaluates site human health risk along six different routes of exposure. The American Society for Testing and Materials' Risk-Based Corrective Action (RBCA) standard, ASTM 1739, establishes a tiered framework for evaluating petroleum release sites on the basis of human health risk. Though much of the risk assessment focus has been on human health risk, regulatory agencies recognize that protection of human health may not fully protect the environment; and EPA has developed guidance on identifying ecological resources to be protected through risk-based decision making. Not every service station or petroleum product terminal site warrants a detailed ecological risk assessment. In some cases, a simple preliminary assessment will provide sufficient information for decision making. Accordingly, the American Petroleum Institute (API) is developing a primer for site managers, to assist them in conducting this preliminary assessment, and in deciding whether more detailed ecological risk assessments are warranted. The primer assists the site manager in identifying relevant ecological receptors and habitats, in identifying chemicals and exposure pathways of concern, in developing a conceptual model of the site to guide subsequent actions, and in identifying conditions that may warrant immediate response.
