DESCRIPTION OF FACILITY AND APPLICATION Lifoam Industries, LLC (the "Permittee") proposes to manufacture expandable polystyrene (EPS) foam products for various customers such as those engaged in the fishing and food industries. The manufacturing operations at the new Facility will use an EPS bead that contains pentane, a volatile organic compound (VOC). The pentane in the bead will be used as a blowing agent to expand the polystyrene before and during product molding. The proposed facility will consist of a pre -expander (EU-PREX1), aging and re -grind bags located in a new aging room (EU -ARI), and up to fourteen EPS molding machines (EU-MLD1, EU-MLD2, EU-MLD3, EU-MLD4, EU-MLD5, EU-MLD6, EU-MLD7, EU-MLD8, EU-MLD9, EU -MLD 10, EU -MLD 11, EU -MLD 12, EU -MLD 13, EU -MLD 14). The facility will also include a new Cleaver -Brooks process steam boiler (EU-CBB1), a Cleaver -Brooks secondary process steam boiler (EU-CBB2), and an emergency generator (EU -EG). None of the combustion equipment is subject to plan approval since they either fall below MassDEP's Air Quality permitting thresholds or will be certified via the Environmental Results Program (ERP); however, the potential emissions from this equipment will be incorporated into the facility's potential emission limits found in Table 2 below. Process steam will be provided to the pre -expander and the EPS molding machines (e.g., manufacturing operations) by EU-CBB1 and EU-CBB2. EU-CBB2 will also provide supplemental process steam for the manufacturing operations whenever needed. These boilers will utilize natural gas as their sole fuel source. The manufacturing process will begin with receiving the EPS beads, typically in 2,200 pound totes. The beads will be manually transferred to a holding tank or `.`bead bin". The beads will then be pneumatically transferred to the pre -expander where the raw beads will be heated with direct contact steam and expanded to 30 to 40 times their original size. The expanded beads then will be pneumatically transferred to one of up to twenty five (25) storage bags located in EU -ARI, where they will be aged for a period of 6 to 48 hours ("pre -puff stage"). As the EPS beads are transferred from EU-PREX1 to EU -ARI, they passively cool to approximately ambient temperature. The aging bags will allow air to enter the bead cells and equilibrate between the top and a small vent on the bottom so that air can pass over the beads, but may be replaced with open mesh aging bags to allow for free flow of pentane out of the silos (bags) into the permanent total enclosure (PTE) space of EU -ARI. Pentane released from the aging bags account for approximately 20% of the total incoming pentane, based on a compliance test performed from October 20 - 22, 2015 at Lifoam's former manufacturing location. Since pentane is approximately 2.5 times heavier than air, pentane released from the EPS beads during the bead aging process sinks to the bottom of the aging Lifoam Industries, LLC Plan Approval Transmittal No. X273896 Application No. NE -17-002 Page 3 of 21 rooms/bags. Captured pentane emissions from EU-PREX1 and EU-ARl are conveyed by centrifugal blowers to a regenerative thermal oxidizer (RTO), specifically to a Ship and Shore Model No. SSE -98X -7.5K RTO (PCD -RTO) for control. After aging in the bead storage bags, the beads are pneumatically transferred to enclosed hoppers, which are attached to the molding machines. The beads are then transferred into the mold where steam is added to form the molded products. The molding machines have been modified so that they exhaust to a vacuum capture system during molding. The steam/air mixture is drawn off the molds, and passed through an air/water separator. The steam condenses to water, leaving the press through a drain line and gravity fed to the cooling water system reservoir. Water from the cooling water system is pumped back to the molding machines where it is used for cooling the parts after they are molded as well as for condensing exhaust steam and cooling hydraulics and equipment. During the molding process, the EPS material is enclosed within the press. The Permittee estimates that 95 percent, by weight (based on emissions testing and mass balance measurements), of the process pentane emissions from the pre -expander, the aging room, and the fourteen molding machines will be captured and sent PCD -RTO for control. The molded EPS products are then stored within the facility's warehouse prior to shipment to the customer. Approximately half of the VOC emissions released from the stored product occur during the first four weeks of storage. Assuming if all of the residual pentane in the* life of the finished EPS product was to be emitted, this amount would equate to up to 28.2 tons per year (TPY) of VOC emissions based on the maximum consumption of 5,130,000 pounds per year of raw EPS beads with a rolling twelve month average pentane content of 5.5 percent by weight. This is a conservative estimate of these fugitive pentane emissions since there still is a significant amount remaining pentane in the shipped product. Two new centrifugal blowers with a combined rated capacity of at least 7,500 standard cubic feet per minute (scfin) will collect VOC laden gases from the collection header which will maintain a negative pressure in the emission unit capture headers serving, each of the following emission units: EU-PREXI, EU -ARI, and EU-MLD1 through EU -MLD 14. PCD -RTO will have a rated air flow capacity of at least 7,500 scfin. PCD -RTO will be equipped with a burner which will burn natural gas as the only fuel of use at a designed energy input capacity of at least 3.1 million. British thermal units per hour (MMBtu/hr). Under normal operating conditions, the set point of PCD -RTO operating temperature will be approximately 1515 degrees Fahrenheit (°F), in order to maintain the minimum operating temperature of 1,500 OF, or such other temperature as may be established pursuant to satisfactory compliance testing results as determined by MassDEP. The effective volume of each combustion chamber within PCD -RTO is approximately 508 cubic feet which is designed to provide a minimum retention time of greater than 0.5 second at an operating temperature of 1,500 OF. Thermocouples will be located within each of the two combustion Lifoam Industries, LLC Plan Approval Transmittal No. X273896 Application No. NE -17-002 Page 4 of 21 chambers. A temperature chart recorder and a data logger will continuously monitor and record the actual operating temperature of PCD -RTO as one (1) minute averages. PCD-RTO's VOC destruction efficiency will be 99 percent of the process air captured or a maximum outlet VOC emission rate of 0.30 pounds per hour, whichever is less stringent. This will be demonstrated through future compliance testing as specified in Table No. 3, Paragraph No. 7. In the event of an emergency shutdown of PCD -RTO, the molding machines will stop production and the process air in the aging room will be re -circulated until such time that PCD -RTO is operating properly again. During nonproduction periods such as weekends when PCD -RTO and EPS bead processes are not in operation or whenever PCD -RTO is down for maintenance, pentane emissions will be re -circulated within EU -ARI until bead processing resumes. Each aging room is equipped with Lower Explosive Level (LEL) monitors with an emergency set point of up to 25 percent of the LEL or 3,750 parts per million (ppm) pentane, and two TRI Model CV9- 36 axial fan systems for emergency ventilation. Should this upset condition take place, an audible alarm shall sound and notify Lifoam personnel via electronic notification. In addition, a data logger shall automatically record the date, time, and the length of time the emergency system had been activated. The Permittee also will be installing and operating up to four (4) American World Trade Group AWT Cameo 18 -CB screen printing machines, or equivalent, to apply printing to some molded EPS products. These four screen printing machines will generate less than 0.3 ton per year of VOC emissions. The Permittee has indicated that the Project may be subject to the Federal New Source Performance Standards (HSPS) for Small Industrial -Commercial -Institutional Steam Generating Units (40 CFR Part 60 Subpart Dc). The Permittee has indicated that the Project may be subject to 40 CFR Part 63, Subpart ZZZZ, National Emission Standards for Hazardous Air Pollutants (NESHAPs) for Stationary Reciprocating Internal Combustion Engines. Since the Permittee's Facility is an area source for HAPs and is defined as an institution, compliance with 40.CFR Part 63, Subpart ZZZZ shall be met by complying with the requirements of 40 CFR Part 60, Subpart JJJJ, "Standards of Performance for Stationary Spark Ignition Internal Combustion Engines". MassDEP is not the delegated authority for these federal regulations since this facility will be a non -major Air Quality source and not subject to MassDEP's Operating Permit Program.
