approved by applicable regulatory agencies. Ihe results of these tests inay be used as part of the jcontractor's QAlyC program. Ilowever, it is the contractor's sole responsibility to meet the |performance criteria specified herein. Therefore, it is expected that the contractor willperform jadditional testing and measurements to assure that materialplaced meets these requirements withoutrejection of batches, exca ration of placed stabili:cd material or reprocessing.

Some of the required testing requires verification of performance after a specified time interval. Ifthe contractor's work plan is such that materialplaced will be covered prior to the end of the |specified time interral, it is the contractor's obligation to either pro ride a product which will meetthe required specifications in the shorter time interval or to accept the contingency that coveringmaterial may need to be removed in order to correct deficient materials.

Contractor may or may not elect to improve the homogeneity of the stabilization plantfeedstock.This can be accomplished by one of two methods, as discuued below. The ntunber of quality controltests required are afunction of the amount ofpre-stabilization homogenization that takes place. Themininnun number of tests required is expressed in terms of the ntunber of batches of stabili:cdproduct placed between tests These testfrequencies are intended as guidelinesfor the startup ofoperationt After the stabilization and placement of no less than 4,fRM) cu.yd. of stabilized product.the testfrequency may be changed in consideration of data obtained, with the approval of the owner,QAlyC contractor and the certification engineer. The criteriafor the testfrequency shall be that theacceptance values are being achieved with at least 99.9 percent confidence. For this specification abatch is defined as the capacity of the haul vehicle used to transport stabili:ed productfrom thestabili:ation plant to the closure cell or S cubic yards of product, whichever is less. If a continuouvcon veyor, slurry pipe or similar system is used, a batch is considered to be S cubic yards.

1.5.1.1 A n equalization and conditioning tank can be used to achieve uniformity offeedstock activity levels and moisture content, even though those characteristics of thesludge and sediments as removedfrom the ponds may vary. Thefrequency ofquality control testing is expressed as afunction of the size of the tank. Theequali:ation tank requirements are discuned in section 2.1).

1.5.1.2 The sludges may be blended in the ponds where they are presently stored prior tomobilization to the stabili:ation plant. If this option is used,its satisfactorycompletion must be measured by sampling and analysis. To accomplish this, a totalof at least 31) samples must be takenfrom each pond and analy:cdfor depleteduranitun (1JU). Ihe sample locations will be determined by the owner and thecertification engineer. The results of this sampling should confirm that the 95percent confidence intervalis equal to or less thanfire percent of the mean.

The balance of this section is divided into two parts depending on the characteristics of the stabili:cdmaterialas discuned in section 1.4.5. Thefirst part addresses the QAlyC requirementsformaterials which are managed as svil-like material. The second part addrenes cast.in-placematerials.

l.S.2 Soil-l.ike Stabilized Material

This section applies to stabili:ed materials which require the addition of mechanical cffort tocompact to a consistency of stabilized material which achieves the performance criteriaspecified in Sections 3../.I through 3.4.4.
