EXHIBIT B 2of3 III. CHEMICAL COSTS Chlorine Cost /Pound Delivered To Site In 1 Ton Cylinders $.14135/lb. Assuming 1 MGD At A Feed Rate Of 100 ppm Chlore- Chemical Cost Is $117.89 /day 125 Days At $117.89 /Day $14,736.25 TOTAL PROJECTED CHEMICAL COST $14,736.25 Cost Summary Site Preparation 5,745.00 Chlorine Equipment & Accessories 11,948.50 Chemical Cost 14,736.25 TOTAL PROJECTED COSTS $32,429.75 * The Site No. 1 at the end of Orange Street was chosen for safety and accessibility. The Site is approximately three hundred (300') feet r� from the nearest house and over one thousand (1,000') feet from the next closest dwelling. Alternate location - Site No. 2 could save $1,000.00 on site preparation, but has excessive traffic. ** Wallace and Tiernam equipment was selected because City personnel have experienced few problems in operation and maintenance with similar units. Rotometers were sized for future use at the two (2) utility plants. Two (2) chlorinators were recommended since a breakdown could cause usage of HTH at a higher cost than the purchase of a second unit. In addi- tion, maintenance of a chlorine dosage large enough to keep downstream complaints to a minimum is probably a major factor in determining whether the City may be required to take far more expensive measures. Since chlorine is such a hazardous material, it is believed the inclu- sion of a detector with an alarm for safety of the general public, a gas mask for on site personnel, and a cylinder repair kit for emergencies are needed for emergencies. * ** It is possible to borrow a breathing apparatus from the Fire Department. However, since there are currently no breathing units at the Pat Mayse Raw Water Pump Station or at the Maxey Water Treatment Plant; it is recommended that an additional mask be purchased at this time, and it can eventually be used at one of these two (2) facilities. ktW t$. a 5 t IF.
