For 2005, six facilities reported approximately 10.1 million pounds of HCBD, representing an increase of
approximately 3.7 million pounds, or 58 percent, compared to the total quantity of HCBD reported for 2001.
Since 2001, the number of reporting facilities remained relatively constant (Exhibit 4.61).

Four facilities located in the Louisiana counties of Ascension, Calcasieu, and Iberville, reported approximately
95.5 percent of the HCBD for 2005 (Exhibit 4.65). 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.

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.

Exhibit 4.67 shows the national trends for how facilities managed HCBD in 2001-2005.

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.

Exhibit 4.68 shows how facilities, by SIC code, managed HCBD in 2005. 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.
