<br />Aecon:Ilng to the U.S. Army Pamph~tlOCP 385-1, the 5X ~vel of contamination exists when "no
<br />signifICant amounts (not enough to prBSeOlan explosive safety hazard) of contamination remain," Al
<br />the SX levellhe "artk:le, !equipment, or bulkllng" does not pose an explosive safelyhllZ8fd and Is safe
<br />for welding, drilling, SIIWIng, etc. and sale to the general public. Therefore, In order for the U.S. Anny
<br />to transferthe Comhusker AAP parcel for SIlIle, It mustfirlil tleclassified as 5X_

<br />Load Line 2 (Section 18. Township 11 North, Range 10) Is located West of Hall County in Grand
<br />lsland, Nebraska (refer to attached Figures 1 and 2 'In Appendix A), and previoUSly cOntained a series
<br />of buildings that had been used in the production of munRions.
<br />
<br />The eJq)losives decontamination and aemolitloo opel1lllons In the Load LIne 2 (Buildings L.1, L.2, L-3,
<br />L-4, L-6, L-7.L-8, Lc10.. L-1 1E, L-11W, L-12, LC14,. L.15. L-16. L.17, L-18, L-19, L-20, L-21, L-22, L.23,
<br />L-25, L~2e, l,27. L-28,L-29, L-30, CH19 and CH20) and thesub6equent certlncatlon of 147-acres or
<br />landparoel wlthlnlhe fenced boundal)l of Load Une 2 was conducted In aCCOl'dance with the
<br />explosives SafetySubmlsslon (ESS) approved by the Department of Defense Explosives Sa~ty
<br />Board (DDESB). The LL~2 Boller House (Building L,24) was left In place since it was excluded from
<br />MKM'$ Scope of W()l1l; thiS 5)( certification letter does not apply to the botIer house and the 0 15
<br />8cteS or parcel.assocIated Yilththe boiler house' foot print (refer to Figure 2),
<br />
<br />During anomaly investigation of the tand parcel wltl1tn thebound8ries of Load Line 2. one burial pit
<br />was encountered that contained asbestos material. The site was mapped using the GPS and malted
<br />u~ng slakes to deUnellle the estimated eldenl of contaminatIon, until follow-on disposition Is
<br />determined by the Department of the Army. This area totaling 0_34 acres is exc;:ludedfrom this 5X
<br />certilication and is shown in Figurll2_
<br />
<br />The EM-Ell MK2 geophysical investigation was not posslb1ewnhin the leach plllocaled at Load Line 2
<br />due to the depth and sIop.a Of the side waHs (refer to Figure 2). the leach pit was Investigated using
<br />the S.chonsl.edt GA52CX magnet.omeler. Ferrous metal anomaUasdetede4 were excavated by
<br />qua~f\ed UXO personnel and delermined 10 be non-MEC related metallic objects.
<br />
<br />The decontamination arnfdemolitlonprocedures resulting In Ihe5X certlnc.tion were executed by
<br />unexpl1Xled ordnance (UXO)pel'$Of1nel who were tanner mlJitaty ExplosIve Ordnance Dl~sal (EOD)
<br />technlclanstnilned In the reCOgnition, assessment and remediation 01 explosive contamination aM
<br />Il8zards.
<br />
<br />Therefore. to the best of our knowledge. the land parcelldenlified ebove have been deeonlamlnBted
<br />to theSX level In accordance with DDESB-approved ESS.
