24、 conducted a survey on the use of diked- area liners around aboveground storage tanks. The data indicate that the effectiveness of liners in protecting the environment is limited because liner systems frequently fail. Further, the resulting data indicate that there are few releases from aboveground

25、storage tanks that would be addressed by diked-area liners. In addition, liner systems are expensive to install and maintain. Several states have enacted requirements to install liners within the tankfield diked area during the past decade. However, there is little published information on the perfo

26、rmance of diked-area liner systems once installed. Because such liners are costly and because changes must be made to facility operations to accommodate the liner system, API members decided to gather information on the performance of diked-area liners after installation. APTS Storage Tank Task Forc

27、e conducted a survey designed to evaluate the effectiveness of diked-area liner systems and document operational problems involved with their use. Responses were received fio, 32 facilities in the marketing and transportation sectors of the petroleum industry. The data show that liner systems are fr

28、equently damaged by day-to-day operations and, thus, would be ineffective in containing a liquid release. Twenty-nine facilities or 9 1 percent of respondents indicated that the liner system had failed to maintain its integrity over time. Among the responding facilities, however, there were few rele

29、ases of the type that would be addressed by diked-area liners. Ninety-one percent of all responding facilities indicated there had been no release since the liner had been installed. Because there were few releases, the data do not directly demonstrate the effectiveness or ineffectiveness of liner s

30、ystems in containing releases. Eighty-eight percent of respondents indicated that they thought there were alternatives to diked-area liners that would be more effective at protecting the environment. The survey data indicated that operators would prefer to use preventive measures, which are generall

31、y more effective in terms of both cost and environmental protection. API survey data also indicated that operators prefer flexible, multi-option approaches, such as those contained in API standards. The data collected by the API survey led to the conclusion that diked-area liners are not the most ef

32、ficient means of protecting the environment given 0 the tendency of liner systems to fail under day-to-day operating conditions; the difficulty of assuring liner integrity; the limited benefit derived from the system in addressing oil discharges; and the high costs associated with installing, as wel

33、l as operating and maintaining the liner system. Measures that prevent aboveground storage tank releases are more effective in protecting the environment and are more cost-effective in the long run. 1 STD-API/PETRO PUBL 3qL-ENGL 1798 0732290 Ob05iBl AT1 W INTRODUCTION Over the past ten years, severa

34、l states have enacted requirements to install liners within the tankfield diked area. These requirements are designed to reduce the permeability of the diked area and contain material in the event of a release. However, there is little published information on the performance of liner systems once i

35、nstalled. Because such liners are costly and because changes must be made to facility operations to accommodate the liner system, API members decided to gather information on the performance of diked-area liners after installation. BACKGROUND To accomplish this task, APIs Storage Tank Task Force con

36、ducted a survey designed to evaluate the effectiveness of diked-area liner systems and to document any operational problems. The survey requested information in three primary areas: The effectiveness-or potential effectiveness-f the liner in containing releases; The effect of the liner on storage fa

37、cility operations; and Preferred approaches to release prevention. The survey did not collect information on undertank liners. SPEC Consulting, an independent firm, was hired to conduct the survey, which was sent to all companies represented on the Storage Tank Task Force. The total number of lined

38、facilities operated by Storage Tank Task force members is unknown; therefore, it is not known what percentage of the population the respondents represent. Participation in the survey was voluntary, and facility names were kept confidential. No instructions were given to potential respondents regardi

39、ng number of facilities to include or location of facilities. Because there are no federal requirements and few states require diked-area liners, a wide geographical distribution of responses was not obtained. Additionally, given the limited nature of the survey, it was not possible to extrapolate f

40、rom survey findings. Responses were received from 32 wholesale distribution terminals-perated by 13 companies-storing gasoline and distillate products. Twenty-nine of the liner installations were retrofit around existing tanks; three of the liners were installed as the tanks were being constructed.

41、In general, the lined area ranged from one to ten acres (four facilities reported lined dikes greater than ten acres, and four facilities reported lined dikes of less than one acre). The lining material used at the facilities included clay geo- composites, extruded sheet, spray-on coatings, coated f

42、abric and others. The survey was confined to petroleum storage facilities due to the unique requirements associated with applying this technology at these sites. While there is an abundance of 3 Previous page is blank STD*API/PETRO PUBL 341-ENGL 1778 D 0732270 Ob05482 738 experience available in the

43、 use of liners for waste management in landfills and surface impoundments, these applications do not lend themselves well to petroleum storage facility operations. A liner at a landfill is used for constant containment and bears a continual load; a liner at a storage tank facility may be used only r

44、arely. Additionally, a landfill liner will have few or no penetrations. Installing a storage tank liner, however, requires cutting the material and fitting it around piping, conduits, pipe supports, pump foundations, cathodic protection cables and other equipment. Further, landfills have little or n

45、o traffic in the containment area. Petroleum storage facilities, on the other hand, require routine vehicular access for ongoing construction, operation, and maintenance activities. SURVEY FINDINGS The following outlines major findings in the three areas of interest: effectiveness of the liner, effe

46、ct on facility operations, and alternatives to diked-area liners. The survey questions and tabulated responses are contained in Appendix A. Liner System Effectiveness The reliability of a liner system and its effectiveness in containing releases were two factors evaluated by the survey to determine

47、the systems overall efficiency. Reliability The data showed that liner systems frequently fail, implying that the liner could potentially be ineffective in containing a liquid release. Twenty-nine facilities or 91 percent of respondents indicated that the liner system had failed in some manner. The

48、major categories of failure included: Damage from vehicular traffic. At larger facilities, vehicle access may be required for daily operation and routine inspection. Additionally, equipment and material must be brought into the diked area for operation and maintenance activities such as painting, ap

49、plying internal coatings, and sandblasting. 0 Material failure. Reported material failures included chemical decomposition from exposure to stored products, reaction with cover soils, and deterioration from weather. Exposure to sunlight and freezing can cause liner material to thin, shrink, and become brittle. These conditions can lead to seam separation and tearing of the material. Additionally, activities required for maintenance of piping and cathodic protection systems may inadvertently cut or rip the liner. 4 I i 0 Failure of the liner around t
