I. Location: Homwood,Inc is located at Pit Road, SR 1812 in Lilesville,NC. Anson County. Directions: From downtown Fayetteville, take Highway 74 west past Rockingham 5 miles to Hailey's Ferry Rd/SR 1801 /Pit Road on the left. WR Bonsal is on the left. Go for— 1/4 miles to Homwood on the right. H. Description: Homwood, Inc is a textile company that warps,weaves, dyes yarn,and heat-sets (tenter frame finishes)and doffs (textures) nylon and polyester knit fabrics. They produce baseball uniforms, automoble seat fabric,cloth for reverse osmosis water purification, gauze, liners for tennis shoes, and cowboy shirts to name a few. The last compliance inspection was on 14 March 2012 by Robert Hayden. Safety: Standard FRO safety equipment required. Plant personnel do not wear helmets. Boilers,high pressure steam leaks, and associated hot piping are the principal hazards. Current throughputs: There facility traditionally employs about 360 people and operates 24 hrs/day, 5 or 6 days/wk,50 wks/yr. A year ago,orders had dropped considerably,but appear to have picked back up. The"through-tenters" number(best measure of production)in 2012 was 9,286,049 lbs. III.

Initial Conference: On 22 May 2013,I,Robert Hayden,FRO DAQ, met with Mr. Kenneth Horne Jr. We verified all FacFinder information. Mr. Horne said that there had been no changes in processes,equipment or formulations since the last inspection. Business is relatively good,but there seems to be a dramatic drop in the demand for football-related clothing,presumably because of reduced schoolrevenue. 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 yarn 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. I checked VE from the operating boilers(zero)and from the two condenser stacks prior to entering the plant.We toured the plant and confirmed the accuracy of the permit and that there were no unpermitted sources. Two boilers were operating on NG. Both tenter/condenser stacks were emitting something,but as the last three years,the sun position,complexity of the emission stream(vapor percentage) and poor background all complicate a valid VEE. It was almost identical to last year's VE. The nature of their synthetic products, especially the ROWPU's cured epoxy membrane, creates smoke. The condenser maintenance logs were very good. VI. Stipulation Review: 213.503 Particulate from combustion. Compliance Indicated. The boilers have been operating on natural gas for the last year 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 Dc requires sulfur content no greater than 0.5%. 213.0521 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 xxxx therms of NG combusted in 2012. 2D.0611 —Condenser/Mist Eliminator Requirements. Elements of the logbook 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 Indicated. Maintenance checks are done daily on the condenser/mist eliminators. Twice yearly they are internally checked for problems. 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. VII.> Chemical Accident Prevention/ 112R Status: Homwood does not store any regulated chemicals in amounts that would make them subject. VII. Compliance History: None in last S years. VIII. Comments and Recommendations: 1. Plant should research tenter operating parameters to maybe reduce opacity; condenser vents 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. Boilers should be labeled as to ID, size and mfg date(at least ID). We researched past permit reviews and found that the boilers from left to right, as observed from outside, are 01, Main 032, Main 031 and 03. 3. Homwood appeared to be in compliance on 22 May 2013..
