8、imated during the five years of this survey. As shown in Figure H, this was 2.9 million wet tons less than the 18.2 million wet tons generated in 1991 and substantially less than generated in 1987-1989. As the vertical variance bars on the estimates indicate, the difference between 1991 and 1990 was

9、 statistically significant (Le., the vertical bars do not overlap). The amount of residuals generated in 1991 and 1990 differed significantly from the quantities estimated for 1987-1 989, which, as shown by the overlap in the variance bars, were comparable.

The greatest change was observed in the generation of Other Aqueous Residuals, a stream generated by only a few refiners, but one that has accounted for more than two thirds of the residu

11、als generated in each survey cycle. The amount of Other Aqueous Residuals generated in 1991 was over 2 million wet tons less than 1990. This reduction reflects movement by some refiners away from deep well injection of residuals, with concomitant changes in the pretreatment and handling of the dilut

12、e residuals that had been suitable for injection. In 1991, four refineries reduced their reliance on deep well injection and are planning total phase-out of this disposal technique. Another refinery obtained a “no-migration“ permit for their Class I well, having demonstrated that continued use of th

13、e well presents no environmental hazards, At the same time, the industry witnessed an increase in the amount of primary sludges generated, the newly listed “F wastesi under RCRA. Two hundred thousand additional wet tons of these materials were estimated as being generated in 1991. It is unclear whet

14、her this represents a true increase in generation, an artifact of the new classification and reporting requirement (e.g., the IF wastes“ were reported for the first time in 1991 as individual streams), or even a peak in generation that resulted from refiners making an effort to remove 3-5 API PUBL*3

19、 1991 (thousands of wet tons) *The quantities for 1987-1990 for Primaiy Sludge were based on the estimates for “Other Separator Sludges,“ a stream that was subsumed in 1991 by the Primary sludge streams. This pattern of an increase in one type of residual being offset by decreases in other streams i

20、s noted in Table 3, which presents the annual data for the 29 individual streams. Increased quantities were estimated for the two largest streams, spent caustics and biomass. For both of these streams, the 1991 quantities were the largest ever generated. Other streams with increases were relatively

21、low quantity streams: residual coke/carbon/charcoal, residual amines, oil contaminated water (not wastewater) and spent sulfite solution. The largest decrease was noted for ppnd sediments which plummeted from its 1990 peak of over one million wet tons to 372 thousand wet tons. This was a return to a

22、 level comparable to the pre-1990 high when many refiners reported closures of surface impoundments that created the spike in the generation curve. Although the quantity of Contaminated soils /solids also dropped from the peak in 1990, this stream remained the third largest. Refiners continued to re

23、port substantial one-time generation quantities of this stream: for 1991, over 400 thousand wet tons or 67 percent of the total amount of Contaminated soil/solids generated resulted from “abnormal“ events.

29、 “K wastes“ also contributed to the overall reduction in generation quantities. DAF float and slop oil emulsion solids both dropped by over 100 thousand wet tons, to 406 and 165 thousand wet tons, respectively. API separator sludge experienced a more modest decrease, but had already undergone some s

30、uccessive, substantial reductions. 3-7 API PUBL*329 94 O732290 0544004 470 M While the quantities of heat exchanger bundle cleaning sludge and leaded tank bottoms were quite small, they nonetheless represented reductions of one third or more. As will be discussed later in this report, many refinerie

31、s attributed these decreases to source reduction activities. Sizeable reductions were also observed for spent acids, nonleaded tank bottoms, other contaminated soils and residual oilskpent solvents, streams that have some similarities in reporting patterns, but more interesting differences. As shown

32、 in Table 4, nonleaded tank bottoms, other contaminated soils and residual oilskpent solvents were reported by at least 59 refineries, a relatively high rate for this survey. Spent acids, on the other hand, was only reported by 20 refineries. What is interesting is that the decrease for spent acids

33、and residual oilskpent solvents reflects a change in generation rate by a only a few of the refineries participating in the survey, while the reductions in the other two streams appears to reflect a more systematic change by the group of refiners reporting each of these streams. These frequency coun

34、ts provide corollary information to the estimated quantity of residuals by the population of refiners, suggesting that there are patterns of generation. From Table 4 it is clear that no individual stream is generated by all refiners in any year. Yet some streams are generated by individual refiners

35、every year, while other refiners generate these streams every other year, less frequently, or not at all. Because residual streams are generated periodically, no single year of data can provide a reliable snapshot of industry practices. Even with several years of data, effort must be exerted to cont

36、rol for this source of variability in the estimated quantity of residual material. 3-0 API PUBL+329 94 m 0732290 0544005 307 m Table 4 Number of Refineries Reporting Each Stream Residual stream Total number of refineries participating Contaminated soils/solids Other residuals NOS FCC catalyst or equ
