This was comparable to the quantity for these streams reported in 1992, and is somewhat less than the high
31、 observed in 1990. A peak in the Primary Sludge residual stream (associated with the regulatory deadlines to close or retrofit surface impoundments) and an increase in Hydroprocessing Catalysts overwhelmed the reductions observed for Pond Sediments and Contaminated Soils, and contribute to making th

33、994 Regarding the management of these streams, treatment continues to account for slightly more than 30 percent of the residuals. Since 1992, however, more material has been recycled than treated. Use of land treatment has diminished substantially and disposal, which peaked between 1990 and 1991, ha
34、s stabilized at a low level comparable to that observed in 1989. These findings were based on the data from 15 residual streams that were included in APIs refining survey. API substantially reduced the number of streams included in its 1994 survey in order to curtail the burden associated with parti
35、cipating in the study. The streams selected for continued study include the most closely regulated residuals and other high volume streams that are generated by the majority of refineries. The 15 streams represent approximately 80 percent of all residuals generated and are the most costly streams to
36、 manage. Refiners responded positively to these changes, reporting that the new, abbreviated forms were much easier to complete. This was reflected in the response rate for the study, which continued to represent more than 60 percent of the domestic refining capacity. Other modifications of the surv
37、ey questionnaire were undertaken to improve the utility of the data. For example, the spent caustic stream was broken out to differentiate the three types of caustics: sulfidic, APIs Petroleum Industry Environmental Performance (PIEP) report (API, 1996) lists 13 residuals. The numbers are comparable
38、, however, since the PIEP report treated three caustic streams as one stream. These streams represent approximately 80% of all residuals generated.

39、PA) and MIS findings on the management of these materials. As noted in the report, both groups found that a substantial portion of the spent caustics are reclaimed, used as commercial feedstock, or reused as secondary materials in other manufacturing processes. -e , * -.* ., . . . *-.-*. a.

ES-2 API PUBLx33b b 0732290 05b02bO 2T9 INTRODUCTION For 1994, the American Petroleum Institute (API) substantially revised its annual refining survey. The scope of the survey was expanded from the single media (wastekesidual) approach by the inclu
43、sion of new questions on wastewater treatment systems and discharges. A series of questions on the management costs for select residual streams was added to the basic survey items on generation quantities and handling practices. To reduce the burden associated with completing the survey, API limited
44、 the number of residual streams included in the survey. Using criteria that included regulatory status, quantity generated, and the magnitude of management costs, the number of streams included in the 1994 survey was reduced from 30 to 15. Data reported in the Executive Summary represents only the 1
45、5 streams surveyed for years 1987-1994. These changes reflect APIs ongoing critical review of the survey effort and its commitment to implement modifications that will improve the quality and utility of data collected. The reductions in the scope of the survey were bom of necessity. Given the overar
46、ching economic considerations directing the streamlining of American industries in the 1990s, refiners view voluntary efforts critically. An important factor in their decision to participate in such efforts is the “value added to their operations from participation in an extemal effort. The addition
47、s to the 1994 survey are NIS attempt to increase the value of the survey. The inclusion of information on capital improvements to the wastewater system and on management costs will be used to create benchmarks that refiners can use to evaluate their performance and the efficiency of their operations
48、. The inclusion of these questions also reflects NIS desire to keep abreast of current environmental performance monitoring trends: multi-media tracking systems and mechanisms to support total cost accounting. The changes in the scope of the survey also have ramifications on the public reporting of
49、the industry- wide estimtes. Whereas the survey previously summarized all residuals generated by the industry, the 1994 effort provides a profile of some of the residuals. Accordingly, the format used in this report focuses on specific streams, in a section-by-section basis. The waste management hierarchy-which recognizes that prevention of waste by source reduction activities and recycling is preferred to treatment and disposal of wastes-has been retained, but is used now to structure the reporting on each of the residual streams. Despite these changes, the p
