Please submit all proposals to: Handcarry to: US EPA; 401 M Street, SW US EPA Mail Code 3803F 499 South Capitol Street, SW Washington, DC 20460 Fairchild Building -- 3rd Floor Attn: Melissa Revely-Brown Washington, DC Attn: Melissa Revely-Brown Environmental Risk Assessments for Three Selected Industries Background: EPA's Office of Science and Technology regulates the discharge of Toxic Pollutants (e.g. heavy metals, organics) by establishing effluent guidelines. These guidelines are developed using Best Available Technology (BAT) and include (1) an assessment of treatment technologies; (2) an assessment of the economics to install and operate the technology; and (3) an assessment of the environmental improvement anticipated after the implementation of the guidelines. Increased attention and emphasis is being given to the environmental impact of BAT guidelines. This impact includes the potential reduction in pollutant loadings. However, it also looks at the more specific changes in water quality that may occur along selected stream reaches, including chemical and biological changes. EPA is responsible for understanding these anticipated changes in water and the effects of water quality on stream ecology that may result from the implementation of BAT guidelines. An evaluation of the potential changes and the resulting benefits is performed on an industry-wide basis. The technical depth of each such evaluation (benefits analysis) will vary according to a number of factors. These factors include the availability and quality of data, specific industrial characteristics such as size and locations, the regulatory strategy, and the estimated cost to implement the regulations. These evaluations are compiled in an environmental risk assessment. Services Required: Environmental risk assessments shall be completed for the following three industries: (1) landfills, (2) incinerators, and (3) transportation equipment cleaning. Each of these environmental risk assessments shall include the following five elements: (1) documented environmental problems; (2) an industry profile that identifies facility locations, receiving streams and POTWs, that quantifies pollutant releases to the environment, and that includes industrial risk-based rankings; (3) a categorized list of released pollutants based on physical-chemical/fate properties and toxicity, and toxic weighting factors for both water and air exposures; (4) projected potential aquatic life and human impacts using localized, simplified stream dilution modeling and reach-specific data such as ambient levels and other pollutant sources including air emissions, sludge disposal modeling, and other modeling as appropriate; and (5) a benefits and risk analysis of the regulation by assessing fate, exposure, human health concerns, and ecological concerns. Landfills: Drafts of the five elements described above have been completed for this industry. The contractor shall incorporate any comments provided by the Project Officer upon award of this contract, and shall update or expand elements as directed in these comments. Incinerators: Drafts of the industry profile (element 2) and the categorization of the released pollutants (element 3) have been completed for this industry. The contractor shall incorporate any comments provided by the Project Officer upon award of this contract, and shall update or expand them as directed by these comments. The contractor shall draft the remaining elements listed above (elements 1, 4, and 5) using any provided by the Project Officer upon award of this contract. Transportation Equipment Cleaning: A draft of the categorization of the released pollutants (element 3) has been completed for this industry. The contractor shall incorporate any comments provided by the Project Officer upon award of this contract, and shall update or expand it as directed by these comments. The contractor shall draft the remaining elements listed above (elements 1, 2, 4, and 5) using guidance provided by the Project Officer upon award of this contract.
