4. I hold a B.S. in crop and soil sciences from Michigan State University (1982), a M.S. in environmental chemistry from Michigan State (1985), and a Ph.D. in soil chemistry from The Ohio State University (1989). I have attached my curriculum vitae as Attachment 1. 5. I have published extensively in the field of soil chemistry and environmental chemistry. I have also co-authored a book titled Soils and Environmental Quality (Third Edition) (Taylor and Francis, 2005), and I am co-inventor of U.S. Patent 6,383,128, "Method for in-situ immobilization and reduction of metal bioavailability in contaminated soils, sediments, and wastes." 6. As part of my scientific and education background, I am familiar with converting between parts-per-million (ppm) and per cent by weight (% (wt)). Both are units of relative measurement, i.e. the express a measurement in terms of the quantity of one thing relative to the quantity of another thing. For acid composition, ppm and % (wt) would be used to express the concentration of the acid itself, or a constituent of the acid. Generally, ppm would be used to express the concentration of constituents present at very low concentrations while % (wt) would be used for constituents present at much higher concentrations. This avoids the use of very small numbers for constituents present at low concentrations (e.g., 500 ppm instead of 0.05%) and the use of very large numbers for constituents present at high concentrations (e.g., 5 % instead of 50000 ppm). These examples also illustrate what is wellknown in the art, which is that converting between ppm and % (wt) requires only the use of the relationship 10,000 ppm = 1.0 % (wt). This follows from the fact that 1 milligram per kilogram (mg/kg) is the same as 1 ppm, where 1 milligram (mg) equals 1/1000 of a gram and one kilogram (kg) equals 1000 grams. Thus, there are 1,000,000 mg in one kg, and 1 mg/kg = 1 ppm. One percent of 1,000,000 is 10,000, (1,000,000 x 0.01 = 10,000) so 10000 ppm = 1.0 %. For example: 20 % (wt) x (10,000 ppm / 1 %(wt) ) = 200,000 ppm Likewise, one may convert from ppm to % (wt): 4200 ppm x (1 % (wt) / 10,000 ppm) = 0.42 % (wt)

7. Engineers, scientists, individuals involved with handling industrial chemical products and those of ordinary skill in the art rely on a document called a certificate of analysis, or COA, to determine the chemical composition of such a product. A COA identifies the chemical constituents and any impurities contained in the product as determined by laboratory analysis. A COA usually lists chemical composition in terms of maximum and minimum parts-per-million or percent by weight expected for the product, plus the actual analysis of the product. 8. Attachments 2­4 to this declaration are three COAs for three different batches of Prayphos P5 phosphoric acid that I have been informed were used at the Colonie site for stabilization of lead in soil. These documents are marked SH041201, SH041245, and SH041293. These three COAs are consistent with similar documents that I have reviewed during my professional career. Each COA lists the constituents of the P5 acid that were measured in the first column, the method by which the analytical company (in this case, Saybolt Canada) measured the concentrations of these constituents in the second column, the "guaranteed" minimum or maximum concentration of each constituent of interest in the third column, the "typical" concentration of each constituent of interest in the fourth column, and the actual concentration of each constituent of interest for the particular delivery in the fifth and final column. 9. The "guaranteed" column expresses the manufacturer's guarantee of a maximum or minimum concentration for each reported constituent. For impurities, the guaranteed maximum is a concentration that will not be exceeded while for the acid itself (expressed as H3PO4 or P2O5) the guaranteed minimum is the lowest concentration that would be found. 10. The "typical" column expresses the typical, normal or average concentration of each reported constituent in the manufacturer's product. 11. The "results" column expresses the actual measurements for the particular batch or shipment associated with the particular COA. These concentrations are generally similar to the "typical" concentrations, and should be less than or equal to the guaranteed maximum for impurities and should be greater than or equal to the guaranteed minimum for the acid itself. The acid purchaser would review these COA documents periodically to ensure they were receiving product that met their specifications.

12. For example, in Attachment 2, the first COA for Prayphos P5 (marked SH041201) shows that the concentration of iron in Prayphos P5 is guaranteed to be a maximum of 10.0 ppm; the typical concentration of iron in Prayphos P5 is typically 7.0 ppm; and the actual concentration of nickel in this particular delivery of Prayphos P5 is 3.2 ppm. 13. One may convert the iron concentrations in Attachment 2 to percent weight using the relationship I discussed above, 10,000 ppm = 1.0 % (wt). I have included the calculations below: Guaranteed: 10.0 ppm iron x (1 % (wt) / 10,000 ppm) = 0.001 % (wt) iron Typical: 7.0 ppm iron x (1 % (wt) / 10,000 ppm) = 0.0007 % (wt) iron Actual: 3.2 ppm iron x (1 % (wt) / 10,000 ppm) = 0.00032 % (wt) iron 14. Sulfate is listed as one of the chemicals of interest in each of these documents and would be considered an impurity in a purified acid such as Prayphos P5. One may convert the concentration of sulfate as expressed in each COA (ppm) to percent weight using the relationship 10,000 ppm = 1.0 % (wt), as done so above for iron. In the table below, I list the concentration of sulfate in each category for each COA, expressed in both parts-permillion and also percent weight, calculated by using the conversion of relationship 10,000 ppm = 1.0 % (wt).

15. Sulfate is present in phosphoric acid as an impurity. The concentration of sulfate in phosphoric acid depends on the level to which the phosphoric acid is purified. While no process for manufacturing phosphoric acid will remove every molecule of sulfate, acid manufacturers can take additional steps to minimize the concentration of sulfates (and other impurities). 16. Under a simple wet process for manufacturing phosphoric acid, the acid manufacturer reacts phosphate minerals, largely calcium phosphate minerals, within phosphate rock with sulfuric acid, and sometimes with weak phosphoric acid, to generate concentrated phosphoric acid. In the wet process for manufacturing phosphoric acid, the manufacturer can vary the quality of the phosphate rock, the temperature of reaction, phosphate concentrations, the addition of various purification chemicals, and the application of various purification processes in the manufacturing process to control the quality and purity of the phosphoric acid. Approximately 90% of all phosphoric acid available on the market is produced by a wet process. 17. Prayphos P5 is a phosphoric acid manufactured by Prayon, Incorporated. Prayon manufactures Prayphos P5 using its a proprietary purified wet process. In Prayon's purified wet process, Prayon carries out additional acid purification steps by using a mixed organic solvent to extract impurities such as sulfate, fluorine, and arsenic, thereby increasing the concentration of the phosphoric acid. Prayon refers to Prayphos P5 as "purified phosphoric acid," as seen on Prayon's Product Specification Data Sheet (Attachment 5) and holds several U.S. Patents for their process, including: 3,970,741; 4,188,366; 4,588,570; and 4,777,027. 18. Despite purification technology, no wet process manufacturing of phosphoric acid can completely remove sulfate, fluoride or other impurities. All phosphoric acid produced by a wet process will include some level of sulfate as impurities. 19. The Fertilizer Manual is an industry reference that describes the manufacture of fertilizers used in Agriculture and Horticulture beginning with raw ingredients and including finished products. The manufacture of various phosphorus-containing fertilizer products requires the use of phosphoric acids of varying purities. For example, the manufacture of liquid fertilizers containing phosphorus requires purifed phosphoric acid to prevent the formation of sludges during storage and transport and to allow a higher phosphate content. Thus, a person skilled -5-

in the art of fertilizer manufacturing would need to be aware of purification processes for phosphoric acid. 20. I have attached a true and accurate copy of the section of the Fertilizer Manual that discusses the purification of phosphoric acid, section 11.8, along with the book cover, copyright page, and table of contents, as Attachment 6. This section includes a discussion of the Prayon process for purifying phosphoric acid, such as Prayphos P5, beginning at page 343. 21. The Prayon process has a number of steps to purify and concentrate phosphoric acid and that produce a purified acid with a sulfate concentration similar to that shown in Table 1. After initial reaction of the phosphate rock with sulfuric acid and possibly a small amount of phosphoric acid, flocculating agents are added and filtration or centrifugation are used to separate the calcium sulfate by-product and other impurities from the acid. Additional additives are used in the acid to reduce the fluoride, arsenic, and heavy metal concentrations. The acid then undergoes solvent extraction to further purify the product. Sulfate, arsenic, and heavy metal concentrations would be further reduced during solvent extraction. Additional steps help to increase the acid concentration. 20. As seen in Table 1, the concentration of sulfate impurities in Prayphos P5 is guaranteed to be a maximum of 350 ppm, or 0.035 % (wt.). The typical concentration of sulfate impurities in Prayphos P5 is 230 ppm, or 0.023 % (wt.). The actual concentration of sulfate impurities in the Prayphos P5 delivered for the Colonie process ranged from 203 ppm, or 0.0203 % (wt.), to 13 ppm, or 0.0013 % (wt.). 21. I understand that the Court has defined the term "technical grade phosphoric acid," or "TGPA," as "phosphoric acid that contains up to 70% (by weight) phosphate (as P2O5) and sulfate (SO42-), typically as sulfuric acid in the range of 2.5% to 7% (by weight) as an impurity." Cl. Constr. 19­20. Note that the certificates of analysis show the concentration of sulfate, but not the particular source of sulfate. This is relevant because less than 100% of the sulfate in Prayphos P5 originates from sulfuric acid; some of the sulfate anions that make up the concentration listed in the COA comes primarily from calcium sulfate. Thus, although the concentration of sulfate as listed in the COAs is an acceptable proxy for the concentration of sulfuric acid in Prayphos P5, the actual concentration of sulfuric acid in Prayphos P5 is less than what is listed in the COA. The typical concentration of sulfate impurities in

Prayphos P5, 230 ppm, or 0.023 % (wt.), is less than One percent of the minimum sulfate dontent of the Court's definition of TGPA. The actual eoflcentration of sulfate in Prayphos P5 is even less. In fact, the concentration of sulfate in Prayphos P5 is, from a chemical reaction point of view, negligible, and would not participate meaningfully in any chemical reactions. Thus, Prayphos P5 is not TGPA as defined in Sevenson's patents and as construed by the Court, and Prayphos P5 does not contain any meaningful amount of suifate. I declare under penalty of perjury that the foregoing is true and correct.
