Such training will include: Spill Prevention Spill Response Good Housekeeping Techniques Materials Management Sediment & Erosion Prevention While operations are conducted on site it will be the responsibility of the superintendent or foreman in charge to train appropriate on -site personnel so that the goals of the SWMP are achieved. SECTION 9: BEST MANAGEMENT PRACTICES The following practices are representative of measures employed within the Sand. & Gravel Industry for limiting pollution associated with runoff.' The specific practices listed below should not be construed as practices that are mandatory or that there is any need on the part of an operator to justify non-use of a particular practice. Obviously, the intent of BMP's is to effect a measure of control over the water quality of stormwater discharges. The practices selected by an operator to achieve this end may evolve with time.

The aggregate used can be a single material, such as a crusher run aggregate or a pit run material, or it can be a combination of coarse and fine aggregates, with or without mineral filler. The binder material used is normally asphalt cement but can also be an asphalt emulsion or one of a variety of modified materials. Various additives, including liquid and powdered materials, can also be incorporated into the mixture. Activities at these sites may include the following: raw material unloading into stockpiles or storage tanks, raw material feed to plant, material batching, raw material storage area, recyclable asphalt disposal area, truck wash out, and water supply and settling lakes. dREADY MIXED CONCRETE These operations mix sand, gravel, cement, and water together to form ready mix concrete, which is hauled to off -site construction projects. Ready Mixed concrete is produced at these locations by combining raw materials in a mixer, which can be stationary (central mix plant) or truck mounted. The raw materials are made up of sand, gravel, cement, water and additives. The sand and gravel is either stored in stockpiles located outside and fed into the plant via loader and conveyors, or it is directly stored in a series of hoppers located directly above the central plant. The remainder of the raw materials are stored in tanks to protect them from exposure to moisture and temperature until they are pumped into the mixer. Once the raw materials are fed into the mixer and combined to form ready mix concrete, the final product is removed from the site by truck. Dry Batching is apportioning out and dumping the mix into the concrete truck or mixer while the cement truck continues to agitate at a lower speed to keep it from hardening before it arrives at the site. Activities at these sites may include the following: raw material unloading into stockpiles or storage tanks, raw material feed to plant, material batching, raw material storage area, recyclable concrete disposal area, truck wash out, and water supply and settling lakes. 4EQUIPMENT FUELING Diesel and/or gasoline tanks are located on site for fueling of equipment. Off -site vendors refill tanks as needed. ❑ QUARRYI N G Drilling and blasting is used to liberate virgin stone from its natural consolidated state. Haul trucks are typically used to take the material to the plant for processing. 10CRUSHING (PROCESSING) portable Processing can consist of as many as 4 different stages of crushing. Screening between crushing stages allows for different product types. Water may or may not be used for material washing, but dust suppression is necessary. [(STOCKPILING (Check if applicable) MOverburden and topsoil Stockpiles may occur in the form of earthen berms. Sand and Gravel: Raw and processed aggregate are stockpiled for future sales. Aggregate mix for concrete production: Aggregate can be stored in stockpiles, and loaded into a ground hopper as needed, and then conveyed to the plant, or loaded directly into a series of hoppers located above the plant which directly discharge into the plant. R(Aggregate mix for asphalt production: Raw material can be stockpiled or put into storage tanks. 4RECLAMATION Reclamation is an ongoing activity throughout the life of a pit or a quarry, and takes place in a contemporaneous fashion as is practicable. Reclamation involves proper sloping, seeding, erosion control and protection from off -site impacts. At the end of the life of an aggregate or industrial operation final reclamation begins. Reclamation is covered under Rule 6 of MLRB regulations and by an approved MLRB Permit. SECTION 1: DESCRIPTION OF INDUSTRIAL ACTIVITIES The activities checked below are activities that are presently performed on -site or are expected to be present in the future. 4STRIPPING The overburden is removed and the material is either sold, hauled away or stockpiled. Stockpiles may be in the form of berms. ❑EXCAVATION - WET MINING ENVIRONMENT (Check one) ❑Dragline: Sand and gravel is excavated below water level and winrowed adjacent to the open water for the purpose of dewatering. After sufficient dewatering has occurred, the pit run material can be conveyed or hauled by means of loader or trucks for final washing and screening. ❑Dredging - bucket type: Material is excavated from below water level and directly conveyed to the plant for final washing and screening. ❑Dredging - pump type: Material is sucked into an underwater pipeline and pumped to the surface. A booster pump is sometimes needed to pump the material through the pipeline to the first processing screen which is sometimes as high as 60' from the ground. BeEXCAVATION - DRY MINING ENVIRONMENT (Check one) dAn alluvial deposit which intercepts ground water which is pumped down ❑A dry terrace deposit wherein ground water is not encountered. When necessary, the water table in the mining area is lowered by means of dewatering ditches and pumps. Material can be excavated within the perimeter ditch without encountering ground water. Moist to dry sand and gravel can 'then be conveyed by means of loader, truck or conveyor belt to stockpiles or processing plant.
