BLANK SLIDE:
SLIDE 1: Title slide [TITLE: PROPER BULK SALT STORAGE]
SLIDE 2: Truck w/ dozer on stockpile REGIONAL STORAGE FACILITIES FOR THE BULK STORAGE OF HIGHWAY DEICING SALT ARE AN ESSENTIAL AND INTEGRAL PART OF WINTER HIGHWAY MAINTENANCE PROGRAMS WHICH PRESERVE AND ENHANCE HIGHWAY SAFETY AND MOBILITY.
SLIDE 3: Covered stockpile IN ORDER TO ENSURE THAT SALT CONTAINED IN STORM WATER RUNOFF FROM A SALT STORAGE SITE DOES NOT HARM THE ENVIRONMENT, TWO FUNDAMENTAL REQUIREMENTS MUST BE MET.
SLIDE 4: Rain on stockpile w/ pad FIRST, THE STOCKPILE MUST BE SITUATED ON A LOW PERMEABILITY PAD AND BASE TO PREVENT DOWNWARD SEEPAGE OF BRINE TO GROUNDWATER.
SLIDE 5: Rain on pile "cover it" SECOND, PRECIPITATION MUST EITHER BE PREVENTED FROM CONTACTING THE STOCKPILED SALT OR, AS AN ALTERNATIVE,
SLIDE 6: Rain on pile "collect & dispose" STORM WATER RUNOFF FROM THE STOCKPILE MUST BE CONTAINED AND DISPOSED OF, REUSED OR DISCHARGED IN ACCORDANCE WITH A REGULATORY PERMIT.
SLIDE 7: "Keep stockpile covered" THE "SALT INSTITUTE VOLUNTARY STORAGE GUIDELINES FOR DISTRIBUTION STOCKPILES" REQUIRE THAT THE STOCKPILE IS COVERED AT ALL TIMES EXCEPT WHEN SALT IS ADDED TO THE STOCKPILE OR LOADED OUT FOR SHIPMENT OR, AS AN ALTERNATIVE,
SLIDE 8: "Use containment" THAT A CONTAINMENT SYSTEM IS IN PLACE TO COLLECT AND HOLD ALL STORM WATER RUNOFF FOR DISPOSAL, REUSE OR DISCHARGE IN AN APPROVED MANNER.

THE GUIDELINES ARE DESIGNED TO MINIMIZE THE POTENTIAL IMPACT OF SALT ON THE ENVIRONMENT AT LARGE SALT STORAGE DISTRIBUTION PILES.
SLIDE 9: Loader at stockpile THEY SET MINIMUM STANDARDS RECOMMENDED BY THE SALT INSTITUTE.

LET'S REVIEW TOGETHER EXACTLY WHAT THE GUIDELINES REQUIRE.
Slides 10-14 (Note: deleted. These dealt with a now-concluded transition period)
SLIDE 15: Case 1155E in dirt pile "Pad design" PAD DESIGN AND CONSTRUCTION REQUIREMENTS
SLIDE 16: "Evaluate site for…" w/ rodman SITE EVALUATION MUST INCLUDE AN EXAMINATION OF CONDITIONS SUCH AS TOPOGRAPHY, HYDROLOGY AND SOILS TO DETERMINE POTENTIAL ENVIRONMENTAL IMPACT ON SURFACE WATER AND GROUNDWATER.
SLIDE 17: "Provide Proper Drainage" SITE DRAINAGE SYSTEMS MUST PREVENT CONTACT BETWEEN SALT AND STORM WATER RUNOFF FROM ADJACENT TERRAIN.
SLIDE 18: Stockpile w/ drain "Provide stable" DESIGN AND CONSTRUCTION OF SUBBASE AND PAD MUST BE ADEQUATE TO ENSURE PAD STABILITY AND PROPER DRAINAGE.
SLIDE 19: Stockpile w/ salt truck "Provide adequate" PAD SIZE MUST BE ADEQUATE TO CONTAIN THE QUANTITY OF SALT THAT WILL BE PLACED AT THE SITE AND TO PROVIDE MANEUVERING ROOM FOR TRUCKS, LOADERS AND OTHER EQUIPMENT.
SLIDE 20: Rain, arrows "Provide lowest perm" SUBBASE AND PAD MUST BE CONSTRUCTED TO ACHIEVE THE LOWEST PERMEABILITY CONSISTENT WITH CURRENT ASPHALT CONSTRUCTION TECHNIQUES.
SLIDE 21: Stockpile Configuration "work wind" STOCKPILE CONFIGURATION IS DETERMINED BY SEVERAL FACTORS INCLUDING SITE CHARACTERISTICS, EQUIPMENT AND UNLOADING METHODS. PREVAILING WINDS MUST BE CONSIDERED WHEN BUILDING THE PILE TO ENSURE THAT THE WORKING END OF THE PILE, ONCE OPEN, WILL BE AT THE DOWN WIND END.
SLIDE 22: "Conical shaped pile. Not Recommended" TO MAKE A CONICAL SHAPED PILE, SALT IS PLACED ON STOCKPILE WITH A FIXED OVERHEAD CONVEYOR DISCHARGING AT ONE POINT. DUE TO ITS SHAPE, A CONICAL PILE CANNOT BE COVERED EFFECTIVELY WITH FLEXIBLE COVERING MATERIAL. USE OF CONICAL PILES IS NOT RECOMMENDED.
SLIDE 23: Windrow shaped pile A WINDROW SHAPED PILE IS MADE BY PLACING SALT ON STOCKPILE WITH A MOVABLE STACKING CONVEYOR OR CLAMSHELL EQUIPPED CRANE. CONSTANT WIDTH OF THE WINDROW MUST BE MAINTAINED AT ALL TIMES.

UPON COMPLETION, THE PEAK OF THE WINDROW SHOULD BE LEVELED TO A NOMINAL WIDTH OF TEN FEET WITH A SMALL DOZER, AND THE CROWN GRADED TO A FOUR- PERCENT SLOPE. THE PURPOSE OF THIS ACTION IS TO PREVENT WATER ACCUMULATION ON TOP OF THE PILE AND TO MINIMIZE UNEVENNESS THAT COULD CONTRIBUTE TO WIND TURBULENCE AND SUBSEQUENT DAMAGE TO THE COVERING MATERIAL.
SLIDE 24: Radial or Kidney Shaped Pile THE SAME CONSIDERATIONS APPLY TO A RADIAL OR KIDNEY SHAPED PILE AS FOR THE WINDROW SHAPED PILE.
SLIDE 25: Sugarloaf Shaped Pile A SUGARLOAF SHAPED PILE IS MADE BY PLACING SALT ON STOCKPILE BY TRANSPORTING IT UP ONTO THE PILE IN DUMP TRUCKS AND/OR RUBBER-TIRED FRONT-END LOADERS. THE SALT IS THEN LEVELED OR PUSHED WITH A BULLDOZER TO OBTAIN THE DESIRED HEIGHT, ELIMINATE TIRE GROVES AND CONSOLIDATE THE APPROACH RAMP.
SLIDE 26: Dust Control/Air BEST MANAGEMENT PRACTICES AND STORM WATER CONTROLS INCLUDE DUST CONTROL AND AIR EMISSIONS

THE FACILITY MUST MEET ALL APPLICABLE GOVERNMENT REGULATORY STANDARDS AND MUST TAKE APPROPRIATE ACTION TO MINIMIZE GENERATION OF DUST AND OTHER AIR EMISSIONS. THESE ACTIONS INCLUDE:

CONTROL OF AIR EMISSIONS MUST INCORPORATE CONSIDERATION OF SUCH FACTORS AS METEOROLOGICAL CONDITIONS, SALT DISCHARGE METHODS AND PREVENTATIVE MEASURES.
SLIDE 27: "Be sensitive to others" Conveyor THE FACILITY OPERATOR MUST CONDUCT OPERATIONS IN A MANNER THAT IS SENSITIVE TO OTHER INDUSTRIAL, COMMERCIAL, PUBLIC AND GOVERNMENT FACILITIES OR RESIDENTIAL AREAS ADJACENT TO OR NEAR THE SALT STORAGE SITE.
SLIDE 28: "Dust suppression.." Conveyor DUST SUPPRESSION PRACTICES FOR CONVEYOR DISCHARGES INCLUDING SELF-UNLOADERS, RAIL CARS, SCREENING STATIONS, TRANSFER POINTS, AND OTHER MATERIAL HANDLING OPERATIONS ARE:

USE AN ELEPHANT TRUNK OR SPOUT WHEN AVAILABLE.

MAINTAIN THE MINIMUM FEASIBLE VERTICAL DISTANCE BETWEEN THE END OF THE SPOUT OR CONVEYOR AND THE HIGHEST POINT ON THE GROUND OR STOCKPILE.

SHIELD OR ENCLOSE ALL TRANSFER POINTS ON CONVEYOR SYSTEMS.
SLIDE 29: "Equip.. Operators" Clamshell bucket CLAMSHELL, END-LOADER, TRUCK, DOZER OR OTHER EQUIPMENT OPERATIONS MUST ENSURE THAT CRANE OR OTHER EQUIPMENT OPERATORS LOWER THE CLAMSHELL OR BUCKET TO THE MINIMUM FEASIBLE DISTANCE FROM THE PILE BEFORE DISCHARGING A LOAD OF SALT.
SLIDE 30: "Clean up spills" Salt truck SALT SPILLED BY ARRIVING OR DEPARTING TRUCKS, RAILCARS OR OTHER VEHICLES OR VESSELS MUST BE CLEANED UP PROMPTLY.

SALT MUST BE LOADED INTO TRUCKS WITHIN THE DESIGNATED PAD AREA AND LOADS MUST NOT EXCEED THE LEGAL OR PHYSICAL CAPACITY OF THE TRAILER OR BOX.

TRUCK TAILGATES MUST BE PROPERLY ADJUSTED TO AVOID SPILLAGE AND THE TAILGATE APRON MUST BE SWEPT CLEAN IF THERE IS SPILLAGE.

ALL TRUCKS MUST BE TARPED BEFORE LEAVING THE SITE.

ROADWAYS MUST BE SWEPT CLEAN TO MINIMIZE TRAFFIC-GENERATED DUST.
SLIDE 31: "Mobile equipment" Muffler IN ORDER TO CONTROL NOISE, THE NEED TO OPERATE MUST BE BALANCED WITH THE AMOUNT OF NOISE GENERATED, THEREFORE:

ALL MOBILE EQUIPMENT MUST HAVE MUFFLERS MEETING DESIGN AND MANUFACTURING CRITERIA CONSISTENT WITH INTENDED USE AND MUST BE IN GOOD OPERATING CONDITION.
SLIDE 32: "Schedule transport" Sign WHENEVER POSSIBLE, SALT DELIVERIES TO THE SITE AND SHIPMENTS TO CUSTOMERS SHOULD BE SCHEDULED DURING NORMAL WORKING HOURS.
SLIDE 33: "Route access" Sign TRUCK ACCESS AND ROUTING INTO AND OUT OF THE FACILITY SHOULD FOLLOW A PRE-DESIGNATED ROUTE WHICH HAS LEAST IMPACT ON THE NEIGHBORHOOD.
SLIDE 34: "Back-up alarms" Salt truck BACK-UP ALARMS SHOULD MEET REGULATORY STANDARDS.
SLIDE 35: "Covering procedures" Covered pile DISTRIBUTION STOCKPILES ARE COVERED TO ENSURE HIGH QUALITY OF THE SALT AND TO PREVENT PRECIPITATION CONTACT AND DISCHARGE OF STORM WATER RUNOFF FROM THE STORAGE PILE. ALL STOCKPILES WITHOUT STORM WATER CONTAINMENT SYSTEMS MUST BE COVERED TO PREVENT PRECIPITATION CONTACT EXCEPT WHEN RECEIVING SALT OR LOADING OUT TO CUSTOMERS.
SLIDE 36: "Approved cover" Covered pile APPROVED TYPES OF COVERING INCLUDE CANVAS, POLYETHYLENE FILMS, FABRICS MADE OF SYNTHETIC FIBERS, AND COMBINATIONS OF THESE MATERIALS USED AS COMPLETE COVERING SYSTEMS.
SLIDE 37: "Cover must be appropriate" THE COVERING MUST BE APPROPRIATE FOR THE SIZE AND SHAPE OF THE STOCKPILE, AND FOR THE METHODS OF RECEIVING SALT SHIPMENTS AND LOADING OUT TO CUSTOMERS.
SLIDE 38: "Cover stockpile in" Rain on covered pile TO MINIMIZE CONTACT WITH PRECIPITATION, THE STOCKPILE MUST BE COVERED IN SECTIONS OR STAGES AS SALT IS ADDED TO THE STOCKPILE.
SLIDE 39: "Seams must be watertight.." 96 MPH Wind SEAMS MUST BE WATERTIGHT AND RESISTANT TO DAMAGE IN WINDS UP TO 69-MILES PER HOUR.
SLIDE 40: "Stockpile covers" Covered pile COVER RETENTION OR HOLD-DOWN SYSTEMS MUST MEET SELECTION CRITERIA CONSISTENT WITH INTENDED USE AND MUST BE INSTALLED IN ACCORDANCE WITH MANUFACTURERS’ RECOMMENDATIONS AND OPERATED IN A MANNER THAT WILL ENSURE PHYSICAL INTEGRITY OF THE COVER.
SLIDE 41: "Covering must be.." Rain on covered pile COVERING MUST BE PROPERLY MAINTAINED TO PREVENT PRECIPITATION FROM CONTACTING THE SALT.
SLIDE 42: "Seal the perimeter" Pile w/ cover & seal APPROVED METHODS OF SEALING THE COVER TO THE STOCKPILE PAD INCLUDE THE FOLLOWING:

THE PERIMETER OF THE STOCKPILE COVER MUST BE SEALED TO THE PAD WITH BALLAST TO PREVENT WASHOUT OF SALT FROM THE TOE OF THE STOCKPILE. BALLAST MUST BE PLACED HIGH ENOUGH ON THE SIDES OF THE STOCKPILE TO MINIMIZE SLACKNESS IN THE COVER AS SALT SHIFTS AND FLOWS BENEATH THE COVER DOWN TO THE PERIMETER OF THE STOCKPILE.
SLIDE 43: "Do not use salt as ballast" Covered pile SALT MUST NOT BE USED AS BALLAST BECAUSE IT WILL DISSOLVE QUICKLY WHEN PRECIPITATION RUNOFF FROM THE COVER FLOWS TO THE PERIMETER OF THE STOCKPILE.
SLIDE 44: "Maintain complete perimeter" MAINTAIN COMPLETE PERIMETER COVER BALLAST UNTIL STOCKPILE IS EXHAUSTED.

WHEN LOADING OUT FOR SHIPMENT, THE FOLLOWING PROCEDURES APPLY:
SLIDE 45: "Remove covering" Partly covered pile REMOVE COVERING AT THE WORKING FACE JUST HIGH ENOUGH TO LOAD OUT THE DAY’S SHIPMENT. THIS WILL MINIMIZE MOISTURE ABSORPTION BY THE SALT AND PROVIDE SECURITY TO THE COVER IF THE WIND DIRECTION SHIFTS TOWARD THE WORKING FACE.
SLIDE 46: "Maintain a working surface" Pile w/ endloader THE WORKING FACE SHOULD BE MAINTAINED PERPENDICULAR TO THE LONG AXIS OF THE PILE BY LOADING ALTERNATELY LEFT/RIGHT AND RIGHT/LEFT.
SLIDE 47: "Avoid creating horseshoe.." Pile w/ endloader AVOID CREATING A HORSESHOE SHAPED WORKING FACE THAT RESULTS FROM REMOVING THE CENTER OF THE PILE AND LEAVING EXTENDED EDGES OR APRONS.
SLIDE 48: "Crush chunks of salt" Hammer head CHUNKS OF SALT THAT FORM AS THE CRUST OF THE PILE BREAKS UP MUST BE CRUSHED AND BLENDED INTO THE PILE DAILY AND NOT ALLOWED TO ACCUMULATE. WHERE CRUSHING IS NOT FEASIBLE, THESE CHUNKS MUST BE COVERED TO PREVENT CONTACT WITH PRECIPITATION.
SLIDE 49: "Maintain covering" pile w/ endloader ADEQUATE COVERING MATERIAL MUST REMAIN AT THE LOWER EDGE OR TOE OF THE WORKING FACE TO PERMIT MAXIMUM POSSIBLE RESEALING OF THE EDGE OF THE COVER WHEN OPERATIONS ARE COMPLETED FOR THE DAY. HOWEVER, CARE MUST BE TAKEN TO AVOID DAMAGE TO COVERING MATERIAL CAUSED BY CASCADING SALT FROM THE UPPER SECTION OF THE WORKING FACE.
SLIDE 50: "Maintain the working" Pile w/ endloader & wind THE WORKING FACE MUST BE ESTABLISHED AND MAINTAINED AT THE DOWNWIND END OF THE STOCKPILE WHENEVER OPERATIONALLY FEASIBLE.
SLIDE 51: "Line earthen collection" STORM WATER CONTAINMENT MUST BE IN PLACE FOR STOCKPILES WITHOUT COVER SYSTEMS. EARTHEN COLLECTION BASINS MUST BE SYNTHETICALLY LINED AND HOLDING TANKS CORROSION-PROTECTED TO ASSURE CONTINUED LOW PERMEABILITY.
SLIDE 52: "Capacity of containment" CAPACITY OF STORM WATER CONTAINMENT MUST BE BASED ON PROPER DESIGN PRINCIPLES INCORPORATING HISTORICAL PRECIPITATION EVENT RECORDS AND DISCHARGE FREQUENCY TO ASSURE ADEQUATE CAPACITY.
SLIDE 53: "Conduct regular inspections" Hand & clipboard THE FACILITY MUST BE MAINTAINED IN A MANNER THAT WILL ASSURE PHYSICAL INTEGRITY CONSISTENT WITH ORIGINAL DESIGN CRITERIA. THIS INCLUDES:

REGULAR INSPECTION OF THE PAD, DRAINAGE, COLLECTION AND OTHER SYSTEMS AFFECTING POTENTIAL DISCHARGE OF STORM WATER RUNOFF FROM THE SITE.
SLIDE 54: "Perform preventative" Hand pointing PERFORMING PREVENTIVE MAINTENANCE SUCH AS PERIODIC RESEALING OF THE PAD TO ENSURE NON-DEGRADATION OF THE LOW PERMEABILITY OF THE PAD AND BASE. EXPANSION JOINTS MUST BE RESEALED EACH SEASON.
SLIDE 55: "Take other corrective" Drain grate TAKING OTHER CORRECTIVE ACTION AS NEEDED TO MAINTAIN STORM WATER DISCHARGES AT LEVELS CONSISTENT WITH BEST MANAGEMENT PRACTICES AND/OR DISCHARGE PERMITS.
SLIDE 56: "Approved disposal" Drain grate USE ONLY APPROVED METHODS OF DISCHARGE OR DISPOSAL OF STORM WATER SUCH AS, DISCHARGE TO SURFACE WATERS, STORM SEWER, SANITARY SEWER OR COMBINED SEWERS, UNDERGROUND INJECTION WELL, SOLAR EVAPORATION AND RECYCLE OR REUSE.
SLIDE 57: "Determine effluent" Chemist with test tube YOU WILL NEED TO DO THE FOLLOWING:

DETERMINE EFFLUENT CHARACTERISTICS.
SLIDE 58: "Obtain appropriate permits" OBTAIN APPROPRIATE PERMITS.
SLIDE 59: "Monitor and maintain" Computer MONITOR AND MAINTAIN APPROPRIATE RECORDS TO ENSURE COMPLIANCE WITH APPROVED PERMIT CONDITIONS AND REQUIREMENTS OF THE GUIDELINES.
SLIDE 60: "Prepare written PPP" FINALLY, YOU MUST PREPARE A WRITTEN POLLUTION PREVENTION PLAN FOR THE FACILITY.
