28. Under Item 1, on page (d)-19, it is stated that minimal winter topsoil stripping will <br />occur. Please describe situations that might warrant topsoil stripping from <br />November through March, and specify that soil stripping and replacement <br />operations will not be conducted if surface soils are frozen or saturated. <br />29. Table 2.05.4(2)(d) Topsoil Stockpile Inventory lists Stockpiles A though K as <br />located west of 27 Rd., and Stockpiles 1 through 10 as East of 27 Road. This <br />listing appears to be reversed. Also, Stockpiles 3 and 4 are both identified as <br />"Mixed" on the table and in text, but on Map 2.04.9-2, Stockpile 4 is listed as <br />"Lift A". Please clarify and amend the table, map, and text as warranted. <br />30. The 2nd paragraph on page 2.05.4(2)(d)-23 references topsoil balances shown on <br />Table 2.05.4(2)(d)-3. The reference should be to Table 2.05.4(2)(d)-4. Please <br />amend the reference. <br />31. The 2nd paragraph on page (d)-28 contains extraneous wording (have had topsoil <br />replacement for the areas which). Please delete the extraneous wording. <br />32. The narrative listing of prime farmland subsoil parameters to be tested, at the <br />beginning of the final paragraph on page (d)-28, does not entirely match up to the <br />list of parameters specified in Table 2.04.9-2, and Table 2.04.9-1 is erroneously <br />referenced. Please delete the entire first sentence of the paragraph, and insert <br />"subsoil" in front of "sample" in the sentence that follows, in the same <br />paragraph. <br />33. The statement on page (d)-29, that "results of this testing revealed that the Bench <br />1 subsoil was suitable for all tested criteria" does not appear to be accurate. <br />Attachment 2.05.4(2)(d)-1 shows that one sample did exceed the conductivity <br />standard by a small margin. Also, we do not concur with the discussion in the <br />Attachment 2.05.4(2)(d)-1 report, which indicates that EC is generally run only as <br />a screening tool, and that EC exceedances do not affect suitability of the soil if <br />SAR is not elevated. Elevated levels of conductivity (i.e. salinity) do affect soil <br />suitability, irrespective of individual ionic effects, by inhibiting the ability of <br />plants to extract water from the soil. Please amend the referenced wording in <br />the Attachment. <br />34. A further concern with EC and pH data reported in Attachment 2.05.4(2)(d)-1 and <br />Attachment 2.04.9-11, (which contain largely duplicate reports and data), is that <br />the data reported for these parameters from the second round of sampling taken <br />from the 2.5 acre grid, are based on 1:1 Soil:Water extract, rather than the <br />standard, permit specified Saturated Paste extract. Interestingly, in the first round <br />of samples (Samples 101 through 106), lab sheets are included which provide EC <br />and pH levels based on both 1:1 and Saturated Paste Extract. The 1:1 extract EC <br />value for Sample 105 (Lab #44950) is 1.94; the Saturated Paste extract value for <br />the same sample is 4.09. This is the sample mentioned in Walsh report as <br />exceeding the 4.0 mmho/cm standard. The Saturated Paste extract value is more <br />9
