Introduction: Martin Marietta Materials, Inc. operates the East Alamance Quarry for the purpose of producing crushed aggregate for use in the construction industry. The quarry operates on property that is located at 1666 Highway 49 North in Haw River,NC . This Storm Water Pollution Prevention Plan(SWPPP)has been prepared in accordance with the conditions of NPDES Permit No.NCG020029, effective July 1, 2021 and valid through June 30, 2025. This permit allows the discharge of stormwater, mine dewatering wastewater, and process wastewater to the surface waters of North Carolina or to a separate storm sewer system conveying discharges to surface waters,from active and inactive mining sites. The SWPPP has been prepared in accordance with good engineering practices and should be used in conjunction with other environmental permits,plans and practices. Definition of a Stormwater Discharge Outfall It is very important with the development of this plan and the oversight of the Permit that there be a clear understanding of what constitutes a stormwater discharge outfall.The Permit defines a Stormwater Discharge Outfall as: "The point of departure of stormwater from a discernible,confined,or discrete conveyance,including but not limited to, storm sewer pipes, drainage ditches, channels, spillways, or channelized collection areas, from which stormwater flows directly or indirectly into waters of the State of North Carolina." This definition is missing the fact that a discharge outfall can also be where the"point of departure"crosses your facility property line. In these cases the stormwater flows into waters of the State of North Carolina at some point past our boundary. Using this definition,it is clear that based on location and flow volume,many of our structural BMPs(basins, sediment traps,etc.)are located on the property in a manner that allows any overflow of treated stormwater to convert to sheet flow, dissipate or infiltrate before reaching the property boundary. The location of undisturbed/vegetated buffers and property boundary offsets are shown on the Mine Map and the Site Plan associated with this SWPPP. In these cases,the discharge of stormwater from these BMPs does not qualify as a Stormwater Discharge Outfall. The responsible parties listed in this SWPPP should evaluate each structural BMP to determine if the stormwater discharge from that location qualifies as an Outfall. Stormwater Outfalls Areas exist on-site in which storm water comes into contact with crushed stone. These areas include stone which is stockpiled for sale or used around the site for maintenance or control purposes. Other areas exist in which we are grading to expose the rock, stockpiling pond fines, or have existing haul roads. Most of the storm water from our crushing operations and grading activities drains to the pit and comingles with the waste water in the sump for settling. This water is then pumped out of the pit and discharged offsite through our permitted wastewater outfall. This location is evaluated by quarry and district staff various times throughout the year to assure this location is in compliance with the stormwater requirements in the permit. If this location's stormwater drainage patterns or conditions change during the year the sampling and monitoring requirements will be 3 NPDES Permit No.NCG020029 adjusted accordingly. The Site Plan will be revised to include the current conditions and identify each stormwater outfall. Cominded Stormwater and Process Wastewater Situations occur on our mine sites where stormwater comingles with process water. DEMLR's position on this is very simple. All stormwater discharges that flow into wastewater and are comingled become wastewater. It is common for our vehicle maintenance area to flow to the pit. In these cases, that water comingles with process wastewater and therefore there is no Vehicle Maintenance Stormwater Discharge. We should note that situation on the Site Plan as justification as to why no Vehicle Maintenance Stormwater Sample is collected.If stormwater from land disturbance areas comingle with process wastewater,the same situation would apply. 1(b). Site Narrative This facility produces crushed stone that is quarried from an open pit. The material is loaded in the pit by front-end loader and transported to the plant by large off-road haul trucks. The material is processed by a series of crushers,screens and conveyors that segregates the material to large inventory piles.Customer trucks are loaded by front-end loaders and they are weighed and ticketed before leaving the property.All of these processes take place outdoors. Any emissions (dust or particulate) created by these processes are controlled by a water truck or by a wet suppression system employed in the plant. Waste materials associated with the production process are minimal. Some rock fines are generated by the washing of stone and this material is captured in the process water recycling system. The material is dipped from this treatment system on a regular basis and disposed of on the property with the overburden or sold as a by-product. Other waste materials include the typical office trash,containers,wooden pallets,scrap metal, etc.that are handled by solid waste vendors. The Mine Permit for this facility does allow for the on-site disposal of certain mining refuse. This material would include land clearing debris,conveyor belts,wire cables,v-belts,air hoses and drill steel.By definition these materials are inert and do not leach out pollutants into the soil or groundwater. If this site has a mine refuse disposal area it will be shown on the Mine Permit-Mine Map and on the Site Plan associated with this SWPPP. Potential Pollutant Sources The types of pollutants likely to be present in the stormwater discharges will vary based on the drainage area. The typical pollutants reasonably expected to be present in runoff from the vehicle maintenance and fueling areas(On-Site Vehicle Maintenance Area Stormwater Outfall as defined in the permit)are settleable solids, suspended solids, and total petroleum hydrocarbons. Good housekeeping practices will keep these types of pollutants to a minimum. The types of pollutants reasonably expected to be present in runoff from the plant, stockpile area,earth-moving,and overburden storage area(Land Disturbance Stormwater Outfall as defined in the permit) are settleable solids and suspended solids. The types of pollutants reasonably expected to be present in pit activities and pit development activities (Mine Dewatering and Process Wastewater Outfall as defined in the permit)are settleable solids and suspended solids. This type of Outfall may include areas that drain to the pit and this could potentially include all of the above types of activities. 4 NPDES Permit No.NCG020029 Inventory of Exposed Materials Storage practices employed at this facility include both indoor and outdoor storage. Outdoor storage would consist of aggregate inventory piles,overburden waste piles,tires,various petroleum products,various large spare parts and equipment, various open-top scrap metal/solid waste containers, and the majority of the mobile fleet. Indoor storage would include the parts washer, paints, aerosols, tools, various small parts and equipment. These are primarily stored in the shop and associated storage areas. Some of the scrap metal/solid waste containers may be stored in closed-top bins. A complete listing of all fuels and bulk oils stored on-site is contained in the Spill Prevention, Control and Countermeasure Plan (SPCC Plan), if required. All fuel and bulk oil tanks are equipped with adequate secondary containment to contain a spill from the largest vessel stored within the structure plus sufficient freeboard. A Secondary Containment Drainage Log,as required by the SPCC Plan,is to be maintained on- site to document containment drainage intervals. Any oil present on the water surface is to be removed prior to draining the structure by acceptable practices. A complete listing of the exposed materials at this facility is located on page 9 and 12. Other exposed areas that may be expected to contribute pollutants to stormwater runoff are inventory stockpiles, stripping areas and berm expansion/earthmoving activities. The location of each of these types of activities is denoted on the Site Plan. 5 NPDES Permit No.NCG020029 1(C). Site Plan Details Site: East Alamance Quarry Instructions: Develop a Site Plan(s)of your site including the site property boundary,topography,footprint of all buildings,structures,permanent paved areas,and parking lots.

Good Housekeeping A Preventative Maintenance and Good Housekeeping Program(PMGHP)is designed to maintain a clean and orderly work environment. Poor housekeeping can result in excess waste being generated and increases the potential for stormwater contamination. The following are some simple procedures to be followed to promote good housekeeping: • Improve operation and maintenance of industrial machinery and processes • Implement careful material storage practices&recycling of used products • Provide trash containers for collection of waste • Schedule routine maintenance • Maintain well organized work areas • Inform employees about good housekeeping practices The quarterly Preventative Maintenance and Good Housekeeping Program(PMGHP)inspection log records dates of inspections & general maintenance and housekeeping around industrial activity areas. These inspection logs are to be maintain onsite and kept for a period of five(5)years. MSHA documentation may be used to support compliance for this program. Preventive Maintenance A preventive maintenance program is a necessary tool to deter problems before they occur. An effective program includes visual inspections and routine maintenance of the mobile fleet, plant equipment and stormwater management devices. Items to be inspected and routinely maintained are listed below: • Mobile equipment(i.e.pit trucks, loaders,etc.)Plant equipment(crushers,screens,conveyors,etc.) • Fuel and bulk oil tanks(including all valves and fittings) • Containment structures • Erosion control structures and stormwater conveyance devices • Pit sump • Detention ponds Martin Marietta has incorporated an Asset Management System for tracking maintenance on all mobile and plant equipment. This is a web-based program that follows the manufacturer's recommendations for proper maintenance and repairs on mobile and process equipment.This system tracks hours of operation,repairs and maintenance.These records are maintained for the life of the asset(mobile or plant item)within the company. Martin Marietta also employs a pre-shift inspection program. This MSHA based requirement covers each workplace and documents if any imminent danger or hazards exist in the area.This visual inspection would note if there were any spills or leaks in the area.These forms are kept on site for one year. 6. Employee Training The required annual SWPPP & SPCC training teach plant personnel, at all levels of responsibility, the components and goals of the SWPPP & SPCC and to create awareness to stormwater pollution prevention concerns. Employees are to be informed of pollution prevention concerns such as: spill prevention and response procedures,preventative maintenance activities,potential sources of stormwater contamination,and materials management practices. An outline of the required topics and completion records for this training can be found on the Annual Training Log for SWPPP&SPCC in this plan. 13 6. EMPLOYEE TRAINING Site: East Alamance Quarry Instructions: Describe the employee training program for your facility below.The program should, at a minimum, address spill prevention and response, good housekeeping, and materials management practices.
