After performing an inspection of the AST It has been determined that the <br />course of action will need to hr: tho tompornry storage of approximately 8,000 <br />gallons of 98% H,SO, for approximately two weeks while the AST is cleaned, <br />inspected, and repaired, Temporary storage of the 98% H,SO, will be in 2,000 - <br />gallon poly tanks suitable for short-term acid use (i e , less than three years <br />continuous contact). However, the poly tanks will need to be fitted with CPVC <br />fittings sealed with VIl ON 0 -rings prior to being put into service as temporary <br />acid storage. ACT will provide for Indian River County's use a double-diaphragrn <br />acid purnp to transfer acid to day tank during AST work. <br />The AST will be cleaned of residual acid and washed with a 3,000 psi pressure <br />washer. Once the tank interior is cleaned the interior surface will be visually <br />examined for pitting, corrosion, and/or cracks. In addition, the steel tank shell <br />will be inspected at randomly selected locations with an ultrasonic thickness <br />gauge to measure tank wall thickness. Following all tank inspections the leaking <br />pipe nipple underneath the tank will be cut away with a new nipple and flange <br />welded into place. <br />After the tank has been repaired the remaining H,SO, in temporary storage will <br />be returned to the AST. The poly tanks will be cleaned on site after all acid has <br />been transferred to the AST. <br />DESCRIPTION <br />UNITS <br />QTY. <br />UNIT <br />TOTAL <br />COST <br />Transfer H,SO, and Clean <br />lump <br />1 <br />$4,262.00 <br />$4,262.00 <br />16,000 -Gallon AST <br />sum <br />Temporary Acid Storage <br />2,000 -Gallon Poly Tanks <br />week <br />2 <br />$120.00 <br />$960.00 <br />CPVC Tank Fitting Upgrade <br />each <br />4 <br />$250.00 <br />$1,000.00 <br />Acid Diaphragm Pump <br />week <br />2 <br />$342.00 <br />$684.00 <br />Poly Tank Gleaning <br />each <br />4 <br />$225.00 <br />$90000 <br />Tank Interior Visual and Ultrasonic <br />lump <br />1 <br />$1,995.00 <br />$1,995.00 <br />i2ilaeettonsum <br />Tank Repair <br />lump <br />1 <br />$650.00 <br />$650.00 <br />Sum <br />Total <br />$10,451.00 <br />V0' d E:C 1 1 VES 299=G1 <br />A*C*T <br />IM:3.1. di•100 NW) IH314V 6 V : Z 1 00-£:Z.-00 <br />
