Book Description
The United States Environmental Protection Agency (EPA) published proposed Effluent Limitation Guidelines and New Source Performance Standards for the Offshore Subcategory of the Oil and Gas Extraction Point Source Category on March 13, 1991 (56 FR 10664). These guidelines include limitations for Best Practicable Technology (BPT), Best Conventional Technology (BPT), Best Available Technology (BAT), and New Source Performance Standards (NSPS) for produced water, drilling fluids, drill cuttings, well treatment fluids, deck drainage, produced sand, and sanitary and domestic waste. As a support document to these regulations, EPA published a Cost-Effectiveness (CE) Analysis (EPA, 1991). This report calculated the CE of several different BAT and NSPS treatment options for produced water and drilling fluids and drill cuttings. Separate calculations were made for restricted versus unrestricted drilling rights and for three different oil costs per barrel. Each treatment option has a different cost and will result in removal of different levels of pollutants. The report calculates the annualized cost for each option and the pound equivalents (PE) removed and expresses the CE as $/PE. While not officially required for decision-making, as long as the CE falls within some reasonable range, the selected treatment option is considered acceptable. This paper examines the premises and assumptions used in the CE analysis and recalculates the CE statistic using alternate assumptions.

Book Description
The US Environmental Protection Agency (EPA) conducted a cost-effectiveness (CE) analysis to estimate the incremental cost of complying with the proposed effluent limitation guidelines (ELGs) for the coastal oil and gas industry (EPA 1995a). EPA's CE analysis calculates the pounds of each pollutant that would be removed if the chosen discharge option is selected. In 1993, EPA issued final ELGs for the offshore oil and gas industry and published an offshore CE analysis. The chemical characteristics of produced water from the offshore region are essentially the same as those of produced water from the coastal region. It was surprising, therefore, that EPA chose a much longer list of pollutants and generally stricter weighting factors for the coastal CE analysis. This report reviews the data, assumptions, and analyses used in EPA's coastal CE analysis and identifies alternate data, assumptions, and analyses that could lead to significantly different cost-effectiveness conclusions. Two alternate lists of pollutants are proposed, along with recalculated weighting factors for several pollutants that contributed a large proportion of the total PEs removed--radium, benzo(a)pyrene, boron, and ammonia. By using different combinations of these variables, a range of revised estimates of CE is calculated.

Book Description
The US Environmental Protection Agency (EPA) conducts a cost-effectiveness (CE) analysis to estimate the cost of complying with each newly proposed set of industrial effluent limitation guidelines (ELGs). CE is defined as the incremental annualized cost of a pollution control option in an industry per incremental pound equivalent (PE) of pollutant removed annually by that control options. EPA's guidelines for conducting the CE analysis require that all costs be expressed in 1981 dollars so that comparison to other industries can be done on a consistent basis. In the results of its CE analyses, EPA presents information showing $/PE values for all the industries for which it has done the CE analysis. These examples indicate that EPA is interested in maintaining consistency and comparability. EPA is not legally bound by the results of a CE analysis; however, if the $/PE for a proposed ELG is calculated to be significantly higher than the $/PEs for other comparable ELGs, EPA might reconsider its proposal. EPA's approach of using an expanded pollutant list and revised weighting factors probably generates a more accurate estimate of the PEs removed for the coastal oil and gas industry, but in doing so, EPA loses the ability to equitably compare this CE analysis to the CE analyses that have been done for other industries. This shortcoming is particularly obvious since the offshore Ce analysis, evaluating a nearly identical waste stream, was completed just two years earlier. Given EPA's concern over consistency and comparability to other industries, it may be appropriate to modify this approach for the coastal CE analysis. Another alternative that would allow EPA to reflect the newest toxicological information and still preserve consistency and comparability would be to recalculate all earlier CE analyses whenever new weighting factors are developed.

Book Description
This book represents the proceedings of the first major international meeting dedi cated to discuss environmental aspects of produced water. The 1992 International Pro duced Water Symposium was held at the Catamaran Hotel, San Diego, California, USA, on February 4-7, 1992. The objectives of the conference were to provide a forum where scientists, regulators, industry, academia, and the enviromental community could gather to hear and discuss the latest information related to the environmental considerations of produced water discharges. It was also an objective to provide a forum for the peer review and international publication of the symposium papers so that they would have wide availability to all parties interested in produced water environmental issues. Produced water is the largest volume waste stream from oil and gas production activities. Onshore, well over 90% is reinjected to subsurface formations. Offshore, and in the coastal zone, most produced water is discharged to the ocean. Over the past several years there has been increasing concern from regulators and the environmental commu nity. There has been a quest for more information on the composition, treatment systems and chemicals, discharge characteristics, disposal options, and fate and effects of the produced water. As so often happens, much of this information exists in the forms of reports and internal research papers. This symposium and publication was intended to make this information available, both for open discussion at the conference, and for peer review before publication.
