Initial Conference: On 26 May 2015,Josh Harris and I, Robert Hayden, both from FRO DAQ, met with Mr. Benny Burr and Wayne Martin(Maintenance Supervisor)to conduct a compliance inspection. Mr.Dale Kelly,who manages most of the air permit records was absent. We verified all FaeFinder information. Mr. Burr said that there had been no changes in processes,equipment or formulations since the last inspection. Business is relatively good, and gradually improving as new markets are found for niche products. V. Process Description: This process may be divided into several distinct operations and are discussed as follows: a. Warping: Yarn is spun onto a single spool for processing in the knitting room. Yarn may also be draw warped which draws the diameter of the yam down by heat and tension. Draw warping effectively reduces the size of the yarn. b. Knitting Room: Spools go onto a mandrel that feeds the knitting machines. c. Middle Warehouse: This is where both finished and unfinished fabric is stored until either future processing is done or shipped to the customer. d. Dye House: Dye is added to the fabric in one of two processes,beam or jet dying. In beam dying, fabric is wound onto a beam with holes that allow the dye to pass through. The dye solution is pumped from the rear of the chamber and passes through holes in the beam and out through the fabric. In jet dying,the cloth is pulled through a tube in the top of the dye chamber by means of a roller and dye water and is constantly in motion through a solution in the bottom of the chamber. They are now adding fire retardant here to reduce VE in the tenter frame. e. Finishing: Here, cloth is passed through one of four tenter frames which heat sets the fabric to reduce shrinking and stretching, and add chemicals which stiffen or coat the material. f. Napping: One of three things may be performed on the material during this process. The fabric will be napped which gives it the appearance of fleece,or shearing which cuts off the top of the fleece, or sueded which sands the fabric. g. Mist Eliminators: The exhaust air from the tenter frames flows through a pre-filter that takes out some of the dry particles with a one inch fiberglass mesh using two trays to pass the air through. They change these daily. Next,the air passes over six cold water coils that helps condense the vapor and send it through the mist eliminator. The coils are washed daily and taken out quarterly for washing. They discovered a problem with the pipes leading to the coils that had to do with pipe threads. They have ordered new pipes so that the coils won't have to be replaced. The mist eliminator houses 18 two-inch fiberglass cylinders that are surrounded by a wire mesh. The condensed vapor passes through the center of the filter then proceeds out the stack. The filters have to be cleaned during a shut down. They have had to replace the filters once already because of epoxy buildup. A different surfactant is being used now that helps cut through the epoxy,but they must first soak the filters weekly. Jet nozzles are located at the bottom center of each filter tube and spray wash water into each. The rinse water is collected at the bottom of the collector unit and sent through a trap to a holding tank for collection and disposal. V. Inspection Summary: I checked the NSPS requirements for boiler B-3. When limited to natural gas,there are few requirements and few opportunities for noncompliance. We checked VE from the operating boilers(zero)and from the two condenser stacks prior to entering the plant. We toured the plant with Mr.Kelly and confirmed the accuracy of the permit and that there were no unpermitted sources. Two boilers were operating on NG. One tenter/condenser stack was emitting something,but as in the last four years,the sun position,background, and complexity of the emission stream(vapor percentage)all complicate a valid VEE. This year the sky was blue, but there was no plume separation(vapor from smoke, if any). The nature of their synthetic products,especially the ROWPU's cured epoxy membrane, creates some smoke. The condenser maintenance logs are typically very good—thorough check monthly -,but could not be found during the inspection, due to Mr. Kelly's absence. VI. Stipulation Review: 2D.503 Particulate from combustion. Compliance Indicated. The boilers have been operating on natural gas for the last three years and AP-42 emission factors indicate compliance. 2D.0515 Particulate control from miscellaneous processes(tenters, presumably). Compliance Indicated. Determined at initial permit review. Likely has improved with condensers. 2D..0516 Sulfur Dioxide control. Compliance Indicated. The boilers were operating on natural gas on the day of the inspection. When fuel oil is combusted,NSPS Do requires sulfur content no greater than 0.5%. 2D.0521 Visible Emissions control. Compliance Indicated,but not positive. VE from the condenser controlling tenter frames 3 and 4 appeared to be around 40%..This stream,however,has a water vapor content,which does not separate from the smoke plume, greatly complicating a valid VEE. 2D.0524 NSPS fuel monitoring and recording(only reqt when burning NG). Appeared In Compliance. No oil combusted since last inspection. Fuel records showed around 12,000 decatherms of NO combusted per month to date in 2015. 2D.0611 —Condenser/Mist Eliminator Requirements. Elements of the logbook(from past observations) include: annual internal inspection- Inspect and maintain structural integrity of duct work and piping leading to and coming from condenser/mist eliminator. Change pre-filter once per week. Implement wash procedure when the pressure drop across the fiberglass Mist Eliminator increases to 7.5 to 8.0 inches of water. Implement wash procedure when pressure drop across water coils increases to 3.0 inches of water. Weight of both the oil and particulate material collected in the condenser/mist eliminator weekly. Compliance "probable"but not verified. Maintenance checks are generally done several times daily on the condenser/mist eliminators when operating.They are currently checked internally each month (records pending). The filters are changed weekly. The facility has not had the any problems will pressure drops on the fiberglass mist eliminator but one is washed daily and the other weekly just to make sure. 2D 0958(c)Work Practices. Compliance Indicated. No rags,buckets or containers with VOC containing materials were left open or unsealed. Very little solvent in use. 2D.1806 Control and Prohibition of Odorous Emissions. Compliance Indicated. No offensive odors were noticed on either side of the property. 2D.0540 Dust Control Compliance Indicated. No dust was seen on the entrance of the facility or in the roadway. Most surfaces are paved. 20 0711 Toxic Air Pollutant Emission Limit. Compliance Indicated. No applicable changes in operating rate or formulations since last permit review. Therefore they are incompliance from review done during their permit application process. VH.> Chemical Accident Prevention/ 112R Status: Hornwood does not use or store store any regulated chemicals in amounts that would necessitate a written Risk Management Program. VH. Non-Compliance History since 2010: None. VHI. Comments and Recommendations: 1. Plant should continue to research tenter operating parameters to maybe reduce opacity; condenser stacks are difficult to read,but may exceed limits. Perhaps inspect early or late in the day,or under unusual meteorological conditions to attempt a better VE read(with detached vapor plume). 2. Several people need to be familiar with the I&M records,not just Mr. Kelly. 3. Recommend a CAI be sent to the facility requesting extracts of the records that was not checked, and recommending other personnel be trained to respond to an air quality inspection(know location of I&M records). Homwood appeared to be in compliance(with concern noted) on 26 May 2015.
