As part of thepollutant loadings calculations, average effluent concentrations for each technology option were developed for both active andinactive landfills. Thisdatabase includes the calculations used to estimate an average effluent concentration for chemical precipitation and biologicaltreatment. The averageeffluent concentration of untreated landfill leachate is also calculated this database for both active and inactive landfills.The Incremental Costs and Pollutant Removals for the Proposed Effluent Guidelines and Standards for the Steam Electric Power Generating PointSource Category (DCN SE01964) provides a detailed description of the calculations used to estimate the average effluent concentrations for each of thetechnology options. The report also provides a description of the calculations used to estimate plant-specific pollutant loadings for each technologyoption. These calculations are executed in the queries contained within the database. The database also includes a listing ofthe specific sampling dataused to calculate the average effluent concentrations for each technology option.
