THE TARGET MOISTURE CONTENT IS 20% BY WEIGHT OF THE TOPSOIL WEIGHT. THE ABOVE WATER CONTENTS ASSUME THE TOP IS DRY. THE AMOUNT OF WATER THAT WILL NEED TO BE ADDED WILL BE DEPENDENT ON THE MOISTURE CONTENT OF THE RAW MATERIALS. ACTUAL AMOUNTS OF WATER USED SHALL BE DETERMINED DURING MIXING. PART 3. COVERED SOIL MIXING PROCEDURES A. MIX COVERED SOIL IN BATCHES OF AN APPROPRIATE SIZE FOR THE EQUIPMENT BEING USED. THE END RESULT IS TO BE A MATERIAL THAT IS UNIFORMLY BLENDED TOGETHER. DO NOT BATCH IN QUANTITIES THAT WILL NOT ALLOW THE EQUIPMENT TO COMPLETELY MIX THE MATERIAL. DETERMINE BATCH SIZE AND QUANTITIES OF EACH MATERIAL NEEDED FOR THE BATCH. B. START WITH HALF OF THE CRUSHED ROCK MATERIAL. C. ADD ALL OF THE TOPSOIL MATERIAL. D. ADD THE SOIL BINDER. E. ADD HALF OF THE ESTIMATED WATER. F. ADD THE OTHER HALF OF THE CRUSHED ROCK MATERIAL. G. MIX THE MATERIAL TOGETHER. H. SLOWLY ADD WATER TO THE MIXTURE AND CONTINUE TO MIX. THE FINAL AMOUNT OF WATER WILL VARY WITH MOISTURE CONTENT OF THE CRUSHED ROCK AND TOPSOIL. ADD WATER IN INCREMENTAL AMOUNTS AND MIX THE MATERIAL BETWEEN THE ADDITIONS OF WATER. I. STOP ADDING WATER AND MIXING WHEN THERE IS A MINUTE AMOUNT OF FREE TOPSOIL REMAINING. THE TOPSOIL WILL COAT THE CRUSHED ROCK AND NOT FALL OUT OF THE MATERIAL. ALL OF THE CRUSHED ROCK SHALL BE UNIFORMLY COATED WITH TOPSOIL. THERE SHALL BE NO CLUMPS OF TOPSOIL OR UNCOVERED CRUSHED ROCK IN THE MIXTURE. J. IF TOO MUCH WATER IS ADDED TO THE MIXTURE, WATER WILL DRAIN OUT OF THE MATERIAL AND THE TOPSOIL WILL WASH OFF OF THE CRUSHED ROCK. IF THIS OCCURS THE BATCH OF MATERIAL SHALL BE DISCARDED AND SHALL NOT BE INCORPORATED INTO THE COMPLETED WORK. PART 4. PLACEMENT OF COVERED SOIL A. PROTECT SOILS AND MIXES FROM ABSORBING EXCESS WATER AND FROM EROSION AT ALL TIMES. DO NOT STORE MATERIALS UNPROTECTED FROM RAINFALL EVENTS. DO NOT ALLOW EXCESS WATER TO ENTER SITE PRIOR TO COMPACTION. IF WATER IS INTRODUCED INTO THE MATERIAL AFTER GRADING, ALLOW MATERIAL TO DRAIN OR AERATE TO OPTIMUM COMPACTION MOISTURE CONTENT. B. ALL AREAS TO RECEIVE COVERED SOIL MIXTURE SHALL BE INSPECTED BY THE PROJECT LANDSCAPE ARCHITECT AND/OR PROJECT ENGINEER BEFORE STARTING PLACEMENT OF MIXTURE. ALL DEFECTS SUCH AS INCORRECT GRADING, COMPACTION AND INADEQUATE DRAINAGE, ETC., SHALL BE CORRECTED PRIOR TO BEGINNING PLACEMENT OF COVERED SOIL. C. CONFIRM THAT THE SUB-GRADE IS AT THE PROPER ELEVATION AND COMPACTED AS REQUIRED. SUB-GRADE ELEVATIONS SHALL SLOPE PARALLEL TO THE FINISHED GRADE. CLEAR THE EXCAVATION OF ALL CONSTRUCTION DEBRIS, TRASH, RUBBLE AND FOREIGN MATERIAL. FILL ANY OVER EXCAVATION WITH APPROVED FILL AND COMPACT TO THE REQUIRED SUB-GRADE COMPACTION. D. INSTALL COVERED SOIL IN 6-INCH LIFTS AND SPREAD UNIFORMLY OVER THE AREA. COMPACT EACH LIFT TO THE REQUIRED PERCENT OF MAXIMUM DENSITY. DELAY PLACEMENT 24 HOURS IF MOISTURE CONTENT EXCEEDS MAXIMUM ALLOWABLE, PROTECT COVERED SOIL WITH PLASTIC OR PLYWOOD DURING DELAY. TAKE PARTICULAR CARE NOT TO DAMAGE UTILITIES WHEN INSTALLING COVERED SOIL. COVERED SOIL THAT WILL BE THE BEDDING FOR UTILITY LINES SHALL BE COMPACTED TO CONFORM TO THE REQUIRED GRADE OF THE UTILITY LINE.

IF THERE IS POTENTIAL FOR THE DIRECT DISCHARGE OF STORMWATER TO A PORTION OF A WATERBODY THAT IS LISTED FOR TURBIDITY OR SEDIMENTATION OR THAT HAS AN ESTABLISHED TOTAL MAXIMUM DAILY LOAD (TMDL) FOR SEDIMENTATION OR TURBIDITY FROM THE CONSTRUCTION SITE, THEN THE BUFFER WIDTH LISTED BELOW MUST BE IMPLEMENTED. WHEN THE DISCHARGE ENTERS AN IMPAIRED WATERSHED UNIT, THE LISTING WILL ONLY BE APPLIED IF THERE IS A HYDROLOGIC CONNECTION BETWEEN THE RECEIVING WATER AND ASSESSMENT WATER BODY CAUSING THE IMPAIRMENT. THE REGISTRANT MUST MAINTAIN ESTABLISHED VEGETATED BUFFERS THAT ARE SIZED AT 50 FEET (HORIZONTALLY) PLUS AN ADDITIONAL 25 FEET (HORIZONTALLY) PER FIVE DEGREES OF SLOPE, OR PROPOSE CONTROL MEASURES OF EQUAL EFFECTIVENESS TO DEQ OR AGENT FOR APPROVAL, AND PROVIDE RATIONALE FOR CHOOSING THE SELECTED BMPS.
