Two facilities, one each in SIC 2812 (Alkalies and chlorine) and SIC 2869 (Industrial organic chemicals, nec) reported most of the pentachlorobenzene for 2001 to 2005, including approximately 93 percent of the total quantity for 2005. A facility in Louisiana that reported the majority of pentachlorobenzene by SIC 2812 facilities burns wastes from offsite sources. Fluctuations in the quantities of pentachlorobenzene reported by this facility are due to variabilities in the quantity and composition of wastes from offsite sources and to fluctuations in production. This facility also noted hurricane-related operational problems in 2005. A facility in SIC 2869 started reporting pentachlorobenzene for 2003 and since then has reported most of this PC within this industry sector. For 2004, this facility attributed increased production and improved flow measurement equipment which resulted in the facility using larger volume flow streams in calculating quantities of pentachlorobenzene. This facility likewise noted hurricane-related operational problems in 2005. How Did Facilities Manage Pentachlorobenzene? Exhibit 4.137.

Nearly 100 percent of the pentachlorobenzene was treated, primarily onsite. Since 2003, a facility in Texas reported 100 percent of the quantity recycled. 25 For additional information on recycled quantities see footnote 8. 4-98 ------- Exhibit 4.138.
