One of the most significant long-term trends affecting the future vitality of the petroleum industry is

2、 the publics concerns about the environment. Recognizing this trend, API member companies have developed a positive, forward-looking strategy called STEP: Strategies for Todays Environmental Partnership. This program aims to address -public concerns by improving our industrys environmental, health a

Such events occur infrequently, and as reported in the survey, are considered “one-time“ incidences. The quantities of these residuals associated with these abnormal events are sub

19、stantial, accounting for the increases in residuals noted since 1989, as well as the variability observed in residual generation between 1990 and 1993. 1990 1941 1992 1993 Generation of Residual Materials ES-2 API PUBLt333 95 rn 0732290 0554320 264 w The pattern observed for TC wastewaters, however,

22、 on the generation and management of residual material in the petroleum refining industry during 1992 and 1993. This study differs from previous survey cycles and respective reports in that two years of data were collected and analyzed simultaneously. The American Petroleum Institute (API) employed

23、this strategy for several reasons. First, collection of the 1992 data had been delayed to avoid conflict with the refiners completion of the Environmental Protection Agencys (EPA) survey conducted under the authority of Section 3007 of the Resource Conservation and Recovery Act (RCRA). This mandator

24、y survey went to the field in September 1993-exactly when API had planned to send out the forms for collection of its own 1992 data. Recognizing that completion of EPAs 142 page questionnaire would require a substantial manpower effort, API opted to delay administration of its survey. API, however,

25、was concerned that a delay in collecting the 1992 data could undermine the utility of these data within the refining industry. Refiners had already expressed concern that the three year lag time in publishing the data made it less useful to them. For example, because the 1991 data were published in

26、1994, information on the first year of land disposal restrictions was released when refiners already had three years of experience with the prohibitions. Thus, while APIs survey reports are viewed as the most comprehensive and current source of data on industry practices by those outside the industr

27、y, to some intimately involved in day-to-day refining operations, the information was too dated to assist in timely management decisions. After discussing the issue with company representatives on APIs General Refining Committee and the Committee on Refining Environmental Controls (CREC), agreement

28、was reached that the 1992 and 1993 data should be collected simultaneously, but the time required to analyze and report results should be reduced substantially. The refiners would therefore shoulder an increased reporting burden, while API, the respective committees involved in the survey, and the c

29、ontractor would be obligated to expedite handling and review of the survey data. This report represents the accomplishment of these goals. The survey materials were mailed to refineries in March, 1994, less than one year ago. Publication of this report with 1993 data represents a substantial reducti

30、on in the lag time to publication. The refiners part in this collaborative effort is noteworthy for it represents the efforts of front line workers in a time when corporate downsizing already made their jobs more demanding. Between 1992 and 1994 when the data was collected, the number of employees i

31、n refining dropped from 121.8 thousand to 108.5 thousand-an 1 1 percent reduction (U.S. Department of Labor, Employment Hours and Earnings, August 1993, June 1994). This reflects the closing of 22 refineries between 1991 and 1993 and reductions in staff at the remaining 161 operating refineries. At

32、the same time, manufacturing increased, from 593 to 618 billion barrels. 1 API PUBL*333 95 = 0732290 0554322 O37 = METHODOLOGY The survey procedures used for the 1992 and 1993 cycles were the same as previously employed. The census design was based on the listings of operating refineries in the Depa

33、rtment of Energys Petroleum Supply Annual for 7992 and 7993. Survey materials were mailed in March 1994. The six week interval originally adopted for form completion was extended to almost seven months to maximize the response rate. Contact was maintained with all refineries during the field adminis

34、tration, with follow-up calls placed to refineries to encourage participation and through a “HELP-line“ staffed by a refining expert. The sections that follow provide more detail on the data collection forms and the estimation procedures used in the study. Data Collection Forms The questionnaire was

35、 provided in both hard copy form and on an automated disk, written using Clipper, a commercially available compiler for dBase. A copy of the data collection form is presented in Appendix A. The survey questionnaire had two sections. The first included nine short-answer questions that focused on refi

36、nery characteristics such as age, size, complexity of processing, and sewer configuration. The second section of the questionnaire was a series of one-page “data sheets“ that collect empirical information on: 1) the quantities of residual materials generated; 2) how they were managed (according to t

37、he waste management hierarchy steps of recycling, treatment, and disposal); and 3) the amount of materials that were reduced as a result of pollution prevention activities. There were 30 of these data sheets for each year, one for each of the residual streams identified in Table I. (Refer to Appendi

38、x A for an example of a data sheet ). The data sheets were virtually the same as used in the 1991 cycle of the survey. The two page format was retained, wherein codes for the management techniques and pollution prevention activities were printed on the back of the preceding page in a different color

39、. The only modifications made to the forms were clarifications of various instructions, such as the inclusionary criteria for several streams (Le., Residual oils and spent. solvents, Spent acids, and High pH/low pH waters), and the selection of the most appropriate code for pollution prevention acti

40、vities. These revisions were considered to be minor since edit checks had previously been performed on these same data elements. 2 API PUBLm333 95 0732290 0554323 T3 Table 1 Refining Residual Streams Category Aqueous residuals Chemicalslinorganic residuais Contaminated soils/solids Oily sludges/othe

44、efining. API has used an equation on each data sheet as a quality control measure: the “inputs“ of residual materials must balance the “outputs.“ Inputs include the quantities of residual material Generated plus Treatment Additives and the Net Removed from Storage (.e., the total amount of material

45、removed from storage minus the amount placed into storage) and constitute the “Total Quantity Managed.“ As depicted in the equation below, this is balanced by the quantities of the residual recycled, treated, or disposed. 3 API PUBL*333 95 0732290 0554324 90T Quantity Generated + Treatment Additives

46、 + Net From Storage = Total Quantity Managed Total Quantity Managed = Quantity Recycled + Quantity Treated + Quantity Disposed Each data sheet also contains a section to capture information on pollution prevention activities that have been performed. In addition to indicating the quantity of waste r

47、educed, respondents are asked to classify the pollution prevention activity according to the codes displayed below and to then briefly describe the activity performed.

49、 OUT-OF-PROCESS RECYCLE Data Analysis The data verification and estimation procedures used were similar to those used previously. Data Verification included 28 automated consistency checks for the variables on each data sheet, as well as final range checks across respondents and comparisons with the data previously submitted by the respective refinery. In all cases, any questionable data were verified by direct contact with the facilities to ensure their accuracy. For each survey cycle, regression analysis has been used to estima
