The present invention provides an underground tank having a vessel assembly and a generally spaced access assembly. That is, the access assembly includes a fuel line, a withdrawal line, and a dome assembly. The fuel line and the withdrawal line have a first end disposed outside the vessel assembly and a second end disposed adjacent to or within the vessel assembly. The first end extends upwardly from the vessel assembly toward the ground surface. The dome assembly is coupled adjacent to the fuel and withdrawal line first end. As such, the vessel assembly may be buried at any depth as the fuel and withdrawal lines may have any length.

1. An underground storage tank structured to be disposed below a ground surface, said underground storage tank comprising: a vessel assembly having a sidewall defining an enclosed space;an access assembly having a dome assembly, a fuel line, and a withdrawal line;said fuel line having a first end and a second end, said fuel line first end being disposed adjacent to said ground surface and said fuel line second end being coupled to said vessel assembly, said fuel line being in fluid communication with said enclosed space;said withdrawal line having a first portion and a second portion, said withdrawal line first portion and said withdrawal line second portion being in fluid communication with each other, said withdrawal line first portion being disposed outside of said vessel assembly sidewall and said withdrawal line second portion being disposed within said vessel assembly enclosed space;said dome assembly coupled to said fuel line first end and said withdrawal line first portion, and spaced from said vessel assembly;said dome assembly includes a generally planar base plate, a collar and a lid;said base plate coupled to said fuel line and said withdrawal line;said collar coupled to said base plate;said lid pivotally coupled to said collar; andsaid base plate, said collar and said lid defining an enclosed dome space. 2. The underground storage tank of claim 1 wherein said collar has a length between about nine and eleven inches. 3. The underground storage tank of claim 1 wherein said collar has a length of about ten inches. 4. The underground storage tank of claim 3 wherein said dome assembly also includes a data plate, said data plate attached to said base plate. 5. The underground storage tank of claim 1 wherein said base plate is spaced between about thirteen to fifteen inches from said vessel assembly. 6. The underground storage tank of claim 5 wherein said base plate is spaced about fourteen inches from said vessel assembly. 7. The underground storage tank of claim 1 wherein said collar is removably coupled to said base plate. 8. The underground storage tank of claim 7 wherein said collar is rotatably coupled to said base plate. 9. The underground storage tank of claim 7 wherein: said dome assembly also includes bottom member, said bottom member attached to said collar;said base plate having at least two keys extending away from said vessel assembly; andsaid bottom member having two arced, keyed openings, each keyed opening is structured to align with one said key. 10. The underground storage tank of claim 1 wherein said withdrawal line includes a pressure release device structured to vent vapor from said vessel assembly. 11. The underground storage tank of claim 10 wherein said pressure release device is structured to operate when said withdrawal line is damaged. 12. The underground storage tank of claim 10 wherein: said vessel assembly enclosed space includes an upper, vapor space and a lower, liquid space;said vessel assembly sidewall having a withdrawal line opening;said withdrawal line pressure release device includes a check lock valve, an outer shell, an inner pipe, and a plenum between said outer shell and said inner pipe;said inner pipe having a first, upper end and a second, lower end, said upper end extending into said dome assembly, said inner pipe extending through said outer shell and said withdrawal line opening into said liquid space;said check lock valve removably disposed in said inner pipe upper end and structured to seal said inner pipe; andsaid outer shell having first end and a second end, said outer shell first end sealingly coupled to said inner pipe upper end, said second end sealingly coupled to said vessel assembly sidewall about said withdrawal line opening, and wherein said vessel assembly vapor space is in fluid communication with said plenum. 13. The underground storage tank of claim 12 wherein: said dome assembly includes a generally planar base plate, a collar and a lid;said base plate coupled to said fuel line and said withdrawal line;said collar coupled to said base plate;said lid pivotally coupled to said collar; andsaid base plate, said collar and said lid defining an enclosed dome space. 14. The underground storage tank of claim 13 wherein said dome assembly also includes a data plate, said data plate attached to said base plate. 15. The underground storage tank of claim 13 wherein said base plate is spaced between about thirteen to fifteen inches from said vessel assembly. 16. The underground storage tank of claim 15 wherein said base plate is spaced about fourteen inches from said vessel assembly. 17. The underground storage tank of claim 13 wherein said collar is removably coupled to said base plate. 18. The underground storage tank of claim 17 wherein: said dome assembly also includes bottom member, said bottom member attached to said collar;said base plate having at least two keys extending away from said vessel assembly; andsaid bottom member having two arced, keyed openings, each keyed opening is structured to align with one said key. 19. An underground storage tank comprising: a vessel assembly having a sidewall defining an enclosed space having an upper, vapor space and a lower, liquid space;said vessel assembly sidewall having a withdrawal line opening;an access assembly having a dome assembly, a fuel line, and a withdrawal line;said fuel line having a first end and a second end, said fuel line first end being disposed adjacent to said ground surface and said fuel line second end being coupled to said vessel assembly, said fuel line being in fluid communication with said enclosed space;said withdrawal line having a first portion and a second portion, said withdrawal line first portion and said withdrawal line second portion being in fluid communication with each other, said withdrawal line first portion being disposed outside of said vessel assembly sidewall and said withdrawal line second portion being disposed within said vessel assembly enclosed space;said withdrawal line further including a check lock valve, an outer shell, an inner pipe, and a plenum between said outer shell and said inner pipe;said inner pipe having a first, upper end and a second, lower end, said upper end extending into said dome assembly, said inner pipe extending through said outer shell and said withdrawal line opening into said liquid space;said check lock valve removably disposed in said inner pipe upper end and structured to seal said inner pipe; andsaid outer shell having first end and a second end, said outer shell first end sealingly coupled to said inner pipe upper end, said second end sealingly coupled to said vessel assembly sidewall about said withdrawal line opening, and wherein said vessel assembly vapor space is in fluid communication with said plenum.
