A. Product shall meet the criteria of or be listed on the Clear Roads Qualified Product List (QPL). Website: https://clearroads.org/qualified-product-list/ B. Product must not contain constituents more than the following established total concentration limits. Results are stated as Parts Per Million (ppm). If product exceeds any of the following constituents, then the bidder shall identify the exception(s) and explain any mitigating circumstances. MaineDOT reserves the right to evaluate any exceptions and decide product eligibility. Phosphorus 250.00 ppm Chromium 1.0 ppm Cyanide 0.20 ppm Cadmium 0.20 ppm Arsenic 5.00 ppm Barium 10.00 ppm Copper 4.00 ppm Selenium 5.00 ppm Lead 1.00 ppm Zinc 10.00 ppm Mercury 0.05 ppm C. Product must have a pH between 3-7 D. Product shall contain a total Divalent Chloride Content (magnesium chloride + calcium chloride) 22% plus or minus 2% to produce a final material having a eutectic (freezing) point of -40°F or lower. E. Product must contain a minimum Magnesium Chloride Content of 16%. F. A 3% solution of the corrosion inhibited chemical product shall have a corrosion value of at least 70% less than that of a 3% solution of Sodium Chloride. (Determined by NACE, National Association of Corrosion Engineers, the standard TM-01-69 as modified by PNS (Pacific Northwest Snow fighters). G. Product must be capable of being used as a stockpile treatment, on-board wetting agent and as a salt brine enhancer. Product must have deicing capabilities on its own as well as be an effective enhancer of salt and salt brine. H. A table showing Freezing Point-Specific Gravity for various percentage dilutions of product in water shall be provided. Table shall include data starting from at least 5% product in water and continue to include the percentage product in water to produce the eutectic (lowest freezing point) composition. I. Bids must be accompanied with the most recent detailed product specification sheet and Material Safety Data Sheet (MSDS). All documents must be clearly legible. MaineDOT reserves the right to request up to two (2) gallons of product, at no additional cost, for verification testing.
