Tank number of each tank within area <br /> Available containment volume <br /> Calculate net available volume of containment in gallons, accounting for contour of land, slope of dike walls, <br /> piping, tanks, buildings, and other obstructions within area. A secondary containment area must be able to <br /> contain at least 100 percent of the design capacity of the largest tank in the secondary containment area plus <br /> displacement from additional tanks within the containment area, with an additional ten percent capacity where <br /> secondary containment areas are exposed to precipitation. <br /> Volume calculation method <br /> M =manual measurements <br /> S=survey showing contour and elevation <br /> Give date of most recent survey or measurement <br /> Attach calculations to the application(new facilities or after major modification) <br /> Construction materials <br /> Identify primary materials used for containment area construction. If dike walls and basin floor are different, <br /> describe each.Attach construction specifications and drawings(new facilities only). <br /> SL=synthetic liner(identify material) <br /> CB=concrete block <br /> CP=poured concrete <br /> CC=coated concrete <br /> ST=steel <br /> NS =native soil <br /> CL=engineered liner using imported clay or bentonite <br /> SA=permeabi�ity of native soil reduced by means of clay amendment <br /> G=geotextile-bentonite mat <br /> Permeability(new and expanding facilities only)(native soil,soil amendment,and clay liners only) <br /> Express permeability as hydraulic conductivity to water in cm/sec. Attach post-construction permeability test <br /> reports. <br /> Area# Tank#'s Volume Calculation method Construction Materials Permeabilit <br /> VIII. Piping <br /> Piping subject to AST major facility permitting includes any piping of two inches or greater inside diameter, located either <br /> aboveground or underground, used to convey a substance to, from, or between any regulated tank(see Minn. R. 7001.4205, <br /> 7151.1200, and 7151.1300). <br /> A. Aboveground piping <br /> For aboveground piping at the facility, describe in general terms the Iocation, fabrication (steel, plastic, other), and any <br /> release prevention, detection and containment safeguards and procedures such as visual inspection, pipe coating and <br /> wrapping, double-walled piping, and leak testing. If there is no such piping, indicate"none". <br /> B. Short-run underground piping <br /> Short-run underground piping includes dike penetrations, roadbed crossings, and other line segments that are less than <br /> 50 feet in length. For short-run underground piping at the facility, describe in general terms the location,fabrication <br /> (steel, plastic, other)and any release prevention, detection and containment safeguards and procedures such as visual <br /> inspection, pipe coating and wrapping,double-walled piping, non-corrosive materials, API Standard 570, and leak <br /> testing. If there is no such piping, indicate"none". <br /> C. Long-run underground piping <br /> Long-run underground piping includes any line segments that are 50 feet or greater in length. Identify each segment as <br /> specified below and describe any release prevention, detection and containment safeguards and procedures used for <br /> each segment, such as visual inspection, pipe coating and wrapping, double-walled piping, non-corrosive materials,API <br /> Standard 570, and leak testing. Provide a scale schematic showing the location of the endpoints A and B and identify the <br /> endpoints below. If there is no such piping, indicate"none". <br /> t-a3-25 <br /> 4/4/07 Page 6 of 8 <br />
