wood preservative to protect wood from decay and insect attack.

Potential Hazards - Pentachlorophenol is toxic; inhalation, ingestion, or skin contact may cause severe
injury or death.

For 2005, facilities in three EPA regions: Regions 4, 6, and 7 reported approximately 97 percent of the total
quantity of pentachlorophenol (Exhibit 4.143). Since 2001, facilities in EPA Region 4 consistently reported
most of the pentachlorophenol, including approximately 52 percent of the total quantity for 2005. For 2005,
facilities in three states: Mississippi, Louisiana, and Kansas reported approximately 84 percent of the total
quantity of pentachlorophenol. A facility in Louisiana reported pentachlorophenol for the first time in 2005,
accounting for approximately 91 percent of this PC in Louisiana. A facility in Kansas that shutdown its
pentachlorophenol manufacturing process also reported this PC for the first time for 2005 and accounted for 100
percent of this PC in Kansas.

Compared to the quantities reported for 2001, facilities in six states no longer reported pentachlorophenol for
2005. On the other hand, a facility in North Carolina reported an increase of approximately 2,800 pounds as a
result of increased production and demand for wood poles. Also, a facility in South Carolina reported an
increase of approximately 37,500 pounds for 2004 and a decrease of approximately 40,500 pounds for 2005.
The facility attributes the fluctuations due to demand for pentachlorophenol treated wood and the use of a
different technique for estimating the quantity of pentachlorophenol in the waste.

For 2005, facilities in three industry sectors (SIC codes) reported pentachlorophenol (Exhibit 4.145). Fifteen facilities in SIC 2491 (Wood
preserving) reported approximately 60 percent of the total quantity of pentachlorophenol for 2005; a facility in Mississippi reported approximately 64
percent of the total quantity within this industry sector. For 2004, this facility and a facility (same company) in South Carolina reported increases of
approximately 46,000 pounds and 37,500 pounds, respectively - accounting for 94 percent of total increase for this industry sector.

Two other facilities, one each in SIC 2879 (Pesticides and agricultural chemicals, nec) and SIC 2812 (Alkalies and chlorine), reported approximately
22 percent and 19 percent of the total quantity of pentachlorophenol, respectively. The SIC 2879 facility, located in Louisiana, reported
pentachlorophenol for the first time for 2005, accounting for approximately 91 percent of this PC in Louisiana. This facility incinerates waste from
other facilities within its company; quantities fluctuate from year to year. The SIC 2812 facility, located in Kansas, permanently shutdown and began
to dismantle it. Contaminated debris containing pentachlorophenol was generated during the dismantling activities.

Exhibit 4.146 shows the national trends for how facilities managed pentachlorophenol in 2001-2005.

Disposal: From 2001 to 2004, facilities disposed of relatively small quantities of pentachlorophenol. However,
in 2005, the quantity increased significantly due to the offsite disposal of contaminated debris (containing
pentachlorophenol) that was generated by the dismantling activities at a facility being shutdown.

Energy Recovery: From 2001 to 2003, facilities used energy recovery for relatively small quantities of
pentachlorophenol. In 2004, the quantity increased significantly by approximately 35,500 pounds. Two
facilities (same company) reported approximately 79 percent of this increase.

Treatment: Since 2001, facilities used treatment as the primary non-recycling method to manage
pentachlorophenol. For 2004, two facilities (same company) primarily accounted for the increase, reporting an
increase of approximately 71,000 pounds of treated pentachlorophenol.

Recycling: For 2001 to 2004, facilities reported recycling only relatively small quantities of pentachlorophenol.
For 2005, two facilities (same company) reported recycling increases of 1.2 million pounds and 890,000
pounds. However, these facilities noted uncertainty whether the quantities they reported as onsite recycling
should indeed be considered recycling and might therefore be in error.

26 For additional information on recycled quantities see footnote 8.

Exhibit 4.147 shows how facilities, by SIC code, managed pentachlorophenol in 2005. For non-recycled quantities, most facilities in SIC 2491
(Wood preserving) primarily treated pentachlorophenol offsite. One Louisiana facility in this industry sector primarily used offsite disposal.

One facility in SIC 2812 (Alkalies and chlorine) used offsite disposal for 100 percent of its pentachlorophenol. This facility, located in Kansas,
disposed of contaminated debris (containing pentachlorophenol) that was generated by dismantling activities during shutdown of the facility.

One facility in SIC 2879 (Pesticides and agricultural chemicals, nec) reported pentachlorophenol for the first time in 2005 and treated the entire
quantity on site.
