One facility, located in Ascension County, reported a large increase of approximately 3.1 million pounds for 2005, attributing the increase to the concentration of HCBD in the feedstock. 4-46 ------- Which Industries Generated Hexachloro-l,3-Butadiene?

Industry Sectors Quantities of Hexachloro-l,3-Butadiene (2001-2005) Primary SIC Code SIC Description Facilities reporting HCBD in This SIC Code (2005) Quantity (pounds) of HCBD Percent of Total Quantity of HCBD (2005) 2001 2002 2003 2004 2005 2812 Alkalies and chlorine 3 6,338,085 3,515,453 3,925,135 4,962,443 7,417,120 73.3% 2819 Industrial inorganic chemicals, nec 1 66,656 80,570 61,608 0 53,535 0.5% 2821 Plastics materials and resins 1 0 0 948 3,194 44,006 0.4% 2869 Industrial organic chemicals, nec 1 0 1,571,362 1,578,608 2,909,070 2,605,986 25.7% Total 6 6,404,741 5,167,385 5,566,299 7,874,707 10,120,647 100.0% For 2005, facilities in four SIC codes reported HCBD (Exhibit 4.66). From 2001 to 2005, facilities in SIC 2812 (Alkalies and chlorine) reported the largest quantities of HCBD. In 2002, the large decrease reported by SIC 2812 facilities was due, in part, to a facility that reported under SIC 2869 beginning in 2002, rather than under SIC 2812. In 2004, SIC 2812 facilities reported a significant increase of approximately 1 million pounds primarily attributed to changes in feedstock composition and groundwater remediation. One facility in SIC 2869 (Industrial organic chemicals, nec) reported an increase of approximately 1.3 million pounds for 2004. This increase was attributed to increased production and improved flow measurement equipment which resulted in the facility using larger volume flow streams in calculating quantities of HCBD. Aside from the approximately 3.1 million pound increase reported by one facility in SIC 2812, several facilities reported decreases for 2005 due to hurricane-related operational problems. 4-47 ------- How Did Facilities Manage Hexachloro-l,3-Butadiene?

Disposal: Since 2001, relatively small quantities of HCBD were disposed. Energy Recovery: One facility reported using energy recovery for its HCBD in 2002 and 2003. Otherwise, facilities reported virtually no HCBD going to energy recovery in other years. Treatment: By far, since 2001, facilities treated most of the HCBD. Recycling: Since 2001, facilities recycled significant quantities of HCBD; an average of 319,000 pounds per year since 2002. 16 For additional information on recycled quantities see footnote 8. 4-48 ------- Exhibit 4.68.

Facilities in all four industry sectors overwhelmingly treated (incinerated) HCBD, mostly onsite. A facility in SIC 2812 (Alkalies and chlorine) reported virtually 100 percent of the recycling of HCBD. 4-49 ------- |
