CLEANUP AND ABATEMENT ORDER NO. 5-00-717 • - 6 - <br /> MUSCO OLIVE PRODUCTS AND THE STUDLEY CORPORATION <br /> MUSCO OLIVES PRODUCTS,TRACY FACILITY <br /> SAN JOAQUIN COUNTY <br /> C. Collection of soil samples for geotechnical analysis from plastic (fat) clay which are <br /> interpreted to comprise aquitard material in the pond borings. The hydraulic <br /> conductivity of each sample shall be determined in an "undisturbed" condition (not <br /> remolded) using a flexible wall permeameter using ASTM 5084-90. The samples <br /> shall also be tested for grain size distribution using ASTM D-422. A minimum of two <br /> samples per boring shall be analyzed. <br /> 3. Within 90 days after approval of the hydrogeologic investigation workplan, the Discharger <br /> shall submit a hydrogeologic report of results, containing the data described in C.2 (above), <br /> scaled figures, and an interpretation of the data collected. <br /> 4. By 3 January 2001, the Discharger shall submit a workplan to further investigate the effect <br /> of wastewater application on soil quality and the fate of the dissolved solids that are applied <br /> to land. At a minimum, the work shall include: <br /> a. A summary of the dissolved solids that are applied to the land application areas and an <br /> evaluation of the fate of the dissolved solids (i.e. adsorbed to site soil, leached to <br /> greater depth, or redissolved and transported off site in surface water). <br /> b. A summary presentation of all the soil quality data collected to date. The presentation <br /> shall include description of the depth, location, and analytical results. <br /> C. A statistical evaluation of the soil quality data to evaluate trends in the data generated. <br /> d. Additional sampling of soil, and composting of samples,to better evaluate the soil <br /> quality. Soil parameters that shall be included are: <br /> i. pH <br /> ii. Cation Exchange Capacity <br /> iii. Percent Base Saturation <br /> iv. Exchangeable Sodium Percentage <br /> v. Soil Salinity <br /> 5. Within 90 days after approval of the wastewater application workplan, the Discharger shall <br /> submit a report on the wastewater application on soil quality. The report shall contain the <br /> data described in CA (above), scaled figures, and an interpretation of the data. <br /> 6. By 31 January 2001, the Discharger shall submit a technical report on the effect of the <br /> application of the wastewater on crops. The report shall evaluate the present health of the <br /> crops grown in the application area, the effect of continued application of wastewater at <br /> present and increased flows, and the potential for increased soil salinity and the resulting <br /> impacts to future agricultural use. The report shall be prepared by a Certified Agronomist or <br /> other person specializing in soil/plant/water relationships. <br /> D. Design and Construction of Long Term Storage and Disposal Facilities <br /> 1. By 30 May 2001, the Discharger shall submit a technical report on the long term storage <br /> and disposal facility improvements. The report shall include the following: <br />
