Tank nominal capacity(gallons). 3. Tank Measurements(use fill location). a. Intermediate tank measurements in inches(to help confirm proper backfill and ballast procedures). (1 After pressure test,measure tank internal diameter prior to back- filling (see I below). (2� After backfill is to top of tank,measure from tank bottom tob o tto m of fitting(see I below). (3) Calculated tank deflection with backfill at tank top(subtract measure- ment a2 from measurement a1).Refer to Table A for max.deflection. b. F1nal Tank Measurements in inches(to help confirm tank has proper support). (1) Initial tank measurement (from a1). (2� After backfill is at subgrade (prior to surface pad),measure from tank bottom to top of fill tube(prior to installation of drop tube)(see U below). (3 Measure from bottom of fitting to top of fill tube(see III below). (4 Calculate tank internal diameter(subtract measurement b3 from b2). (5) Tank deflection(subtract measurement b4 from b1).Refer to Table A. Measu ement Instructions All meas,rements for vertical deflection are made from the bottom of the tank to the bottom of the fitting. All meas rements should be made in inches using a standard nonmetallic gauge stick. All measurements should be made through the fill fitting (use the same fitting for all measurements).
