The sludge composition in <br /> conjunction with the proposed application rate should have minimal <br /> impact, and should not require the inclusion of additional conditions, <br /> parameters, monitoring requirements, or other modifications to the <br /> current NPDES permit . <br /> Copies of the permit application prepared by Black & Veatch Engineering, <br /> and of the minutes of the latest meeting of the principal parties <br /> involved is enclosed for your reference. Please advise us of any <br /> concerns or comments that you, or the Water Quality Control Division may <br /> have relative to any impact this project may have on the water quality of <br /> Tenmile Creek. <br /> erely, <br /> rank.
