6、results of the Aboveground Storage Tank Survey conducted for the American Petroleum Institute by Entropy Limited. The survey covers all segments of the petroleum industry, namely marketing, refining, transportation and production. A total of 76,708 tanks were counted, including 75,369 tanks in the A

7、PI field survey plus 1339 additional tanks in the marketing area from data supplied by the Petroleum Marketing Association of America (PMAA). This survey does not include what is believed to be a small part of the total tank population such as tanks at user locations (e.g., utility fuel storage). Ba

8、sed upon statistical analysis of these surveyed tanks into stratification groups, the total number of tanks nationally is estimated at approximately 700,000. This includes approximately 89,000 in marketing, 30,000 in refining, 9,000 in transportation and 572,000 in production. Table S-1 shows the nu

The largest portion (82.8%) comprises the smallest size category, 26 to 500 Bbls. The next largest portion (6.4%) is the 500 to 1000 Bbls size range.

Detailed breakouts by material and construction types for each industry sector are given in the corresponding sections of this report. The figures for distance from navigabl

15、e waters were also surveyed. Totalling the numbers of facilities in marketing, refining and transportation, 48.8% are over 5 miles, 20.1% are 1 to 5 miles, 7.8% are 1/2 to 1 mile, 7.4% are 1/4 to 112 mile, and 15.9% are less than 1/4 mile from navigable waters. For production, 23.9% of the tanks are

16、 over 5 miles, 21.0% are 1 to 5 miles, 14.5% are 112 to 1 mile, 15.0% are 1/4 to 112 mile, and 25.6% are less than 1/4 mile from navigable waters. In the estimated national totals, the percentage of facilities covered by SPCC regulation (40CFR112) is 91.6% for marketing, 100% for refining, and 37.3%

17、 for transportation. The percentage with written spill contingency plans is 96.0% for marketing, 97.6% for refining and 79.7% for transportation. In production, these figures were tabulated on a tank basis, with 58.2% of the tanks covered by SPCC plans, and 47.6% covered by written spill contingency

18、 plans. The bulk of transportation facilities are not covered by SPCC regulations, but are covered by DOT-oil spill contingency regulations. 2 API PUBL*3OL 89 m 0732290 05LLb74 803 m MARKET1 NG There are an estimated 88,529 aboveground storage tanks at marketing sites in the U.S. representing the to

19、tal demand for petroleum products, including motor gasoline, jet fuel, distillates, residuals and other. To achieve this estimate, API survey data has been supplemented with marketing facility surveys from the PMAA. The data supplied by PMAA members (Table M-4b) are incomplete in same respects, so t

20、hat they have not been combined with the API marketing totals (Table M-4a). Valid surveys from API companies were received for 395 facilities while results from an additional 169 facilities were obtained through the, P“. In order to obtain a reliable estimate of total U.S. tankage, it is necessary t

21、o stratify the Sam le. Unstratified extrapolation based on sales figures, which are 116,659 MB E l/Month for the 395 API survey respondents and 17,131 MBbl/Day nationally as of the end of 1986 , would produce an underestimate because of the distribution of survey respondents by sales. Unstratified e

22、xtrapolation based on number of facilities, which is 395 for the API survey and 12,424 for the nation as a whole (the 1982 Census of Wholesale Trade estimates the number of bulk plants and terminals at 10,131 and 2,293 respectively-1P gas facilities excluded), would produce an overestimate because t

23、he API survey has a disproportionate number of large terminals, which tend to have a high number of tanks per facility (see Table M-2). Stratification of the components of the tankage by type of material is not possible because of differences between the portions categorized as heavy oils in nationa

24、l data definitions and the portions so categorized in the survey responses. Of course, it would be necessary to separate aboveground from underground storage capacity, and this generally precludes using this factor for the stratification. Stratified estimation is possible by keying against total fac

25、ility storage capacity. Storage capacity in the national census technically includes both AST and UST storage. However, virtually all storage at terminals and roughly 90% of bulk plant storage is above ground. Stratification is based on five facility storage capacity groups: below 2,500 Bbl, 2,500 -

26、 24,999 Bbl, 25,000 - 149,999 Bbl, 150,000 - 499,999 Bbl, and 500,000 Bbl and above. * “1987 Energy Statistics Sourcebook,“ p. 239. 3 API PUBL*3OL 89 W 0732290 05LLb75 7YT W Table M-I gives the estimation of ASTs based on these groupings.

The capacity per facility ratio for the survey closely matches Census An estimated adjustment to exclude USTs from the extrapolation can be achieved by reducing the U.S. tank totals by 10% for the bulk plant subpopu- lation.
