Cost Effectiveness Analysis of Final Effluent Limitations Guidelines and Standards for the Coastal Subcategory of the Oil and Gas Extraction Point Source Category

This report supports the Effluent Limitations Guidelines and Standards for the Coastal Oil and Gas Industry ("Coastal Guidelines"). The report analyzes the cost-effectiveness of five regulatory options for three wastestreams organized into two wastestream groups under the current regulatory baseline and under an alternative baseline. In this document, EPA compares the total annualized cost of each regulatory option to the corresponding effectiveness of that option in reducing the discharge of pollutants for each wastestream. EPA evaluates the effectiveness in terms of costs per pound of pollutant removed, weighted by the relative toxicity of the pollutant. The rationale for this measure, referred to as "pound equivalents removed," is described later in this document.
