J.R. Simplot Company Inspopn Fonii 2 2 May 2000 <br /> I asked Ms. Murphy where the lysimeter sampling parts and leachate collection sump pump were located. <br /> She did not know and stated that J.R. Simplot laboratory technicians who took samples would know. I <br /> stated that I would add this item to-my next inspection agenda. Ms. Murphy invited me to attend the next <br /> sampling event to observe their procedures. <br /> Subsequently, we toured the process plant. All water is drained to the interior through several sumps <br /> located around the asphalt and concrete lined process plant. While driving around, I noticed an area <br /> where earthen material was exposed and wood framing was installed. Ms. Murphy and Mr_ Bill Baterton <br /> stated that a concrete slab was being replaced because of a sulfuric acid drip. We discussed how concrete <br /> is porous and liquids can penetrate the slab, especially sulfuric acid. I asked them if they knew how much <br /> acid had dripped onto the pad-and for how long. Neither knew the details of the slab replacement.:,I asked <br /> if the County had been notified,and they said no. I asked if soil samples had been taken to verify whether <br /> sail below the previous coiicrete'slab l aci been impacted'1Tliere is aconcern that con taminated`•soil could. <br /> threaten groundwater quality as a source. Ms. Murphy stated that they had not taken sam les. I <br /> recommended that they ensure that:the soil was free of contaminants prior fo pouring the-concrete'wliicfi ' <br /> they said was planned for the following Monday. I stated that it would be prudent to take representative <br /> soil samples and test the pH. Ms. Murphy asked my authority to require.this;to occur.. I,q!4oted:.the,Basin <br /> Plan (Water Quality Control Plan, Third Addition, Sacramento River Basin and San Abagz'in River <br /> Basin), which is referenced in-the WDRs.OrderNo. 97-229. The Board's.authority,requires.the,protection <br /> of the benef cial uses of waters-of the State. Contaminated soil threatens,waters of the.State,and shoutd be <br /> removed:as:a source if found-.to,be impacted from spills. Ms. Murphy agreed toltake.representative' . <br /> samples;(horizontal and vertical extent:of the area) and test.the pH. Mr. Bill Baterton stated that it would <br /> be wise of them to ensure that the soil was clean before they poured the cement slab, otherwise they might <br /> have to.excavate the new concrete slab. <br /> Ms.Murphy and I proceeded to her:o.ffice where I-was introduced to her supervisor Mr. Hervey Homer, <br /> Manager of Technical Services. Ms. Murp�y and I discussed the recent notice of non-.compliance letter I <br /> had sent her earlier that month. She statedr that the company's response letter would be forthcoming and <br /> had no questions at that time. Ms. Murphy graciously offered a schematic map.and brochure of the plant. <br /> 'She also offered the name, address, and phone number of the individual, representing EPA Region 9, who <br /> recently performed a document inspection of the J.R. Simplot Company. Ms. Murphy asked for a copy of <br /> the photos that I took during the inspection. I agreed to have two prints made so I could provide a copy to <br /> the company. <br /> I left J.R. Simplot Company at approximately 3:00 pm. <br /> SUMMARY: <br /> A copy of this inspection and cover.I etterwill be forwarded to J. R. Simplot parry. The cover letter <br /> shall request the sampling and analysis plan and results from the soil where the sulfuric acid spill <br /> occurred. <br /> j <br />
