o Follow Environmental Protection 1.3.12 in the PWS

17. We understand all the existing dosing and control equipment incl. Sulfuric acid day tanks, Spill containment, Chemical mixing tanks, metering pumps etc., belong to WPAFB. Selected new vendor would get to use all of them for proper water treatment. Please confirm.

o Yes

18. Should dosing or control equipment fail during the contractual period, does the supplier's contractual price include equipment repair or replacement or would equipment needs be separately purchased outside the service contract?

o Equipment is outside of this contract and therefore does not apply.

19. The solicitation provides installed capacity of the equipment that need water treatment. The actual operating load and hence the chemical usage is commonly much lower than this capacity. Hence we request water usage readings for individual facilities and/or actual chemicals used for the past two years.

As this information is available only to the current vendor, for fairness of all potential bidders, please consider sharing this information.

o The water usage is not tracked by CE as every facility does not have a water meter. Chemical usage is governed by the contractor based on actual test results. However, a list of chemicals in use for the past two years are as follows:

Condenser Water Inhibitor Sodium Hypochlorite Sulfuric Acid Boric Acid Boiler Water Dispersant Sodium Sulfite Neutralizing amine Sodium Hexametaphosphate Vapor Phase Corrosion Inhibitor Isothiazolin Sodium Chloride Flake Caustic Closed Loop Inhibitor Soda Ash Potassium Hydroxide Sodium bisulfite Bromine tabs

20. What was the last awarded contract number? Who was the awardee? What was the awarded bid?

o The current Industrial Water Treatment Contract is FA8601-12-C-0062, awarded to Lombardi
