ABSTRACT
ERAs evaluate the likelihood that adverse ecological effects may occur or are occurring as a result of exposure to one or more stressors caused by human activities (U.S. EPA, 1992). The ERA process is described in detail in Chapter 3. Review of contractor produced ERA deliverables is necessary to ensure that the science is consistent with current standards, calculations are verifiable, and all product and performance standards have been met. This chapter offers tools for critically reviewing contractor produced deliverables during the production of interim drafts or following production of a draft final report. No matter when critical review occurs, its purpose is to ensure production of scientifically credible products.
