Norwesco #43128 ten thousand (10,000) vertical translucent white polyethylene gallon tank and at minimum must consist of the following in order to be considered for award: High-density vertical translucent white poly tanks; Overall Height – one hundred sixty (160) in +/- ten (10)%; Overall Diameter – one hundred forty-one (141) in +/- ten (10)%; Four (4) lifting lugs; Must be embossed with a date stamp in the month/year format; Must have embossed gallon measurement markers; Self-supporting vertical tanks requiring no framework; Ultraviolet A (UVA) and Ultraviolet B (UVB) resistant; Made of polymer material to withstand storage of salt brine solution with a minimum specific gravity of one and six tenths (1.6). Specific gravity is the ratio of the chemical weight per gallon divided by the weight of water per gallon eight and thirty-three hundredths (8.33) pound per gallon). As an example, if a chemical weighs ten (10) pound per gallon, the specific gravity of the chemical is ten (10.0)/ eight and thirty-three hundredths (8.33) = one and two tenths (1.2). (Metric: kilogram/cubic meter or gram/liter);
