PAGE 2 JANUARY 13, 1994 BARBARA PAVLIK At four discrete spots on refuse pile #4, tests shall be performed to ensure that proper compaction has been obtained per section 4.10.4(b), on all lifts constructed since mid-1992. The test procedure is listed below. 1. Before beginning the testing, a determination shall be made that the test being performed accurately represents the refuse pile waste bank. The test results from the dozer pit will be compared with the results obtained by the Troxler moisture- density gauge or equivalent to ascertain that the test results are not significantly different. 2. A dozer and/or backhoe shall cut a sloping trench from the top of the waste bank to the top of the lift where the last compaction test will be performed. The vertical cut shall be approximately 10 to 15 feet deep depending upon the location. The depth of the cut was determined by the number of lifts constructed since mid-1992. 3. During the cut made by the dozer and/or backhoe, care shall be Taken to ensure the waste bank material to be tested is disturbed as little as practicable. 4. A Voxlermoisture-density gauge or equivalent shall be used to determine the density of the waste bank where the cut was made. The test shall begin two feet below the existing grade and shall be made on two foot intervals until reaching the bottom lift. 5. The test locations, procedures, and data shall be monitored by a licensed professional engineer or his representative. 6. During the testing process, if it is determined that the material being tested has or may have a dry density different than those previously measured, samples may be taken so analysis may be performed. If samples are taken to re-examine the dry density, test results of the entire test performed may be delayed by up to four weeks. 7. Once the tests have been completed and the results have been compiled, a report written to review the results of the test shall be submitted to DMG.
