I presented my credentials to Eric Schol, the facility's Safety and Environmental Manager, and informed him that this was an EPA inspection to evaluate the facility's compliance with the applicable requirement of the Resource Conservation and Recovery Act (RCRA). This inspection included a review of the facility's process areas, waste treatment areas, and onsite landfill. During this review we collected samples of the facility's waste streams and disposed waste for analysis by EPA's Region 6 Laboratory. FACILITY DESCRIPTION The Sloan Valve Augusta Arkansas facility operates as a brass foundry manufacturing plumbing fixtures. This process utilizes thermally moldable sand to create the brass molding forms. This sand is cycled through the process multiple times until it is no longer suitable for use. The now spent mold sand demonstrates the hazardous waste characteristic for lead toxicity. Sloan Valve elects to treat this waste and dispose of it in an onsite landfill. The following sections discuss the facility units where this material is managed. Sand Plant The sand plant uses a series of ball mills and screens to recycle the sand used in the foundry molds. It is the primary point of generation for the spent mold sand which is treated and eventually disposed in the onsite landfill. While most of the used sand in the sand plant is returned to the process, sand collected at dropout 01-S is destined for treatment and disposal. Sand collected at dropout 02-S may also be designated as waste based on determination by the sand plant supervisor. Pangborn Shot Blast Unit The Pangborn Shot Blast Unit is used for shot peening of the brass fixtures and also removes residual sand. The spent sand mixed with shot residues is conveyed to a tank where it is accumulated prior to disposal in the onsite landfill. Incorporated into the conveyor system is a treatment reagent addition point which applies the dry treatment reagent, Free flow 100, directly onto the conveyor with the spent sand and shot residue. Ball Mill Building The waste sands are treated in the ball mill building. The first step uses a ball mill to pulverize the waste sand. It is them passed through a magnet and screen to remove any remaining brass which can be reclaimed. The waste sand is then conveyed to a tank where it is accumulated prior to disposal in the onsite landfill. A Freeflow 100 addition point is incorporated into this conveyor system. Zinc Oxide Collector Off-gas emissions from the furnaces in the melting center are routed through a dust collector. The material collected in the dust collector is composed primarily of zinc oxide; however, due to impurities, it is considered a hazardous waste. The zinc oxide is shipped off-site for reclamation through Waste Service, Inc. (WSI). 2 Sloan Valve - Augusta, AR June 24-26, 2014 Section II - OBSERVATIONS On June 24, 2014, we conducted our walkthrough of the facility's process and waste management areas. During this walkthrough we reviewed the facility's hazardous waste management practices and identified areas for sampling the following day. Hazardous Waste Staging Area The facility maintains a designated area of the facility for the temporary storage of containers of hazardous waste. This area is separated from the production areas by a low metal wall that is clearly marked as a hazardous waste management area. Within this area the facility stores containers of floor sweep, waste sand, used baghouse bags, and other materials designated as hazardous waste. At the time of this inspection, we noted the following areas of concern: -One container of waste filter bags was open. -One open hopper of floor sweep was stored in the area. This hopper was open and unlabeled. According to Eric Schol the contents of this hopper would be treated in the ball mill building as a hazardous waste. North Baghouse Pad The North baghouse pad is the concrete lined area located on the northeast corner of the building and serves as the foundation for the baghouses SN11 and SN12. When we visited this area on June 24, 2014, we observed a material which appeared visually similar to the facility's mold sand deposited on the soils on the periphery of this concrete pad. As a result of this observation, we designated this area as a sample collection point for June 25, 2014. Sand Plant The Sand Plant is located in the southeast corner of the production building. The waste sand outlet points dump into open-topped, pre-labeled, steel hoppers. At this time of this inspection, we observed one container of waste sand staged near the sand unit while waiting to be moved to the ball mill building. The container was open when we observed it. Ball Mill Building When we visited the ball mill building June 24, 2014, the unit was in operation with the east door open. A small fan was positioned in the doorway for the comfort of the employees, but visible dust was being generated by the ball mill. This building was designated as one of the sample collection points for June 25, 2014. When we returned to the unit on June 25th, we observed piles of sand on the floor beneath the ball mill and decided to include this material in our sampling activity. In addition, we identified a breach in the north wall of the building. 3 Sloan Valve - Augusta, AR June 24-26, 2014 Landfill At the time of this inspection, the landfill was nearing its permitted capacity. The active area of the landfill was limited to an area of approximately 20 yards wide and 50 yards long. The remaining portion of the landfill had been covered with a newly installed earthen cap. The active area had been recently graded. We designated this area for sample collection and included the waters collected at the toe of the active slope. Sampling On June 25, 2014, David Robertson and I returned to the facility to collect samples in the areas we identified on June 24th. We photographed each sample location and collected sample. We provided a split of each sample to Eric Schol. Key to Collected Samples Sample S01 - A multi-point composite sample collected from the perimeter of the north baghouse pad.
