For 2005, 632 facilities reported approximately 17.2 million pounds of naphthalene, representing an increase of
approximately 7.2 million pounds, or 72 percent, compared to the total quantity of naphthalene reported for
2001 (Exhibit 4.114). Approximately 200 more facilities reported naphthalene for 2004 compared to prior
reporting years. Many of these facilities began reporting naphthalene for 2004 due to the lowering of the TRI
reporting level for this chemical from 1.0 to 0.1 percent. Although the number of reporting facilities increased
significantly due to this change, there was not a corresponding significant increase in quantity. For example,
although approximately 50 more facilities in SIC 5171 (Petroleum bulk stations) began reporting naphthalene
for 2004, the overall quantity reported for that year actually decreased by approximately 24,000 pounds.
Off-spec fuel and/or tank cleanout wastes might be the source of the naphthalene. Some of the reasons behind
the increased quantities reported for 2004 and 2005 are provided below.

Since 2001, facilities in EPA Region 6 reported the largest quantities of naphthalene, including approximately
57 percent of the total national quantity of naphthalene for 2005 (Exhibit 4.117). Facilities in Texas reported
the largest quantities of naphthalene, including approximately 50 percent of the total national quantity of
naphthalene for 2005. Other highlights concerning trends for the reported quantity of naphthalene in states
include:

•	In Texas, the quantity of naphthalene reported increased 1.2 million pounds in 2004 and 4 million
pounds in 2005. Two facilities accounted for most of these changes. One facility reported increases of
approximately 1.3 million pounds in 2004 and 2.4 million pounds in 2005 due to compliance with air
pollution standards and a change in how material sent to flaring was calculated. The second facility
reported an increase of approximately 1.6 million pounds due to demolition and tank/releases cleanup
efforts in 2005.

•	In West Virginia, one facility primarily accounted for the significant decrease in 2002 and subsequent
increases in 2003 and 2004. This facility incinerated larger quantities of naphthalene due to difficulties
encountered in trying to separate the naphthalene for recovery.

•	In Louisiana, a facility that purchased fuel oil (containing naphthalene) from a waste broker, as an
alternative source of energy for its boiler, reported an increase of approximately 227,000 pounds for
2004.

•	In Michigan, a facility that is being shut down reported increases of approximately 160,000 pounds and
592,000 pounds for 2004 and 2005, respectively. These increased quantities are primarily from residual
processing, tank cleanouts, etc. as a result of shutting down this facility.

4-84


-------
•	In Alabama, a facility that is being shut down reported increases of approximately 589,000 pounds and
166,000 pounds for 2004 and 2005, respectively. These increased quantities are primarily from clean-up
activities and the cleanout of tanks in preparing for demolition of the facility.

•	In Indiana, one facility accounted for most of the fluctuating quantities; this facility reported increases of
approximately 634,000 pounds and 314,000 pounds for 2002 and 2003, respectively as well as a
decrease of approximately 862,000 pounds for 2004. This facility attributes the fluctuations to the
quantity of paint (containing naphthalene) it uses and the number of steel coils painted per year.

For 2005, facilities in 59 industry sectors (SIC codes) reported naphthalene. Exhibit 4.119 shows the quantity of naphthalene for the 10 industry
sectors in which facilities reported approximately 90 percent of this PC for 2005. Some highlights concerning trends for the reported quantity of
naphthalene within industry sectors include:

4-86


-------
SIC 2911 (Petroleum Refining)

•	Facilities in this industry sector reported approximately 31 percent of the total quantity of naphthalene
for 2005. Since 2001, the quantity of naphthalene increased each year, including large increases of
approximately 1.3 million pounds in 2004 and 2.7 million pounds in 2005. A facility in Texas
accounted for much of these increases, reporting increases of approximately 1.3 million pounds and 2.4
million pounds due to compliance with air pollution standards and re-calculation of material sent to
flaring.

SIC 2865 (Cyclic crudes and intermediates)

•	Since 2001, the quantity of naphthalene has increased significantly by approximately 3 million pounds.
Much of the increased quantity was generated from residual processing, tank cleanouts, etc. as a result
of shutting down several facilities, including a facility in Michigan that reported increases of
approximately 160,000 pounds and 592,000 pounds for 2004 and 2005, respectively and a facility in
Alabama that reported increases of approximately 589,000 pounds and 166,000 pounds for 2004 and
2005, respectively. For 2005, a facility in Texas also reported an increase of approximately 1.6 million
pounds due to demolition and tank/releases cleanup efforts

SIC 3479 (Metal coating and allied services)

•	Facilities in this industry sector reported an increase of approximately 762,000 pounds of naphthalene
for 2002 and a decrease of naphthalene of approximately 635,000 pounds for 2004. A facility in Indiana
primarily influenced these quantities by reporting an increase of approximately 634,000 pounds for 2002
and a decrease of approximately 862,000 pounds in 2004. This facility attributes the fluctuations to the
quantity of paint (containing naphthalene) it uses and the number of steel coils painted per year.

SIC 2869 (Industrial organic chemicals, nec)

•	Since 2001, facilities in this industry sector reported quantities of naphthalene that fluctuated
significantly from year to year. Some of the notable quantities reported include:

o For 2002, a facility in Louisiana reported an increase of approximately 257,000 pounds and a

facility in Texas reported an increase of approximately 103,000 pounds,
o For 2003, a facility in Louisiana reported an increase of approximately 201,000 pounds and a

facility in Texas reported an increase of approximately 149,000 pounds,
o For 2004, a facility in Louisiana reported an increase of approximately 227,000 pounds as a
result of using fuel oil (containing naphthalene) as an alternative source of energy for its boiler.
A facility in Texas reported an increase of approximately 118,000 pounds as a result of cleanup
of a release.

o For 2005, a third facility in Texas reported a decrease of approximately 383,000 pounds due to
the variability in crude oil that was refined.

SIC 2821 (Plastics materials and resins)

•	Facilities in this industry sector reported significant increases of naphthalene for 2002 and again for
2005. For 2002, a facility in Texas reported an increase of approximately 228,000 pounds. For 2005, a
facility in Texas reported approximately 152,000 pounds-a one time reporting of this PC by this facility.
A second facility in Texas reported an increase of approximately 456,000 pounds.

SIC 2879 (Pesticides and agricultural chemicals, nec)

•	A facility in West Virginia reported a decrease of naphthalene of approximately 1.2 million pounds for
2002 and an increase of naphthalene of approximately 495,000 pounds for 2004. This facility sent its
naphthalene to offsite recovery in 2002, but due to difficulties encountered in trying to separate the
naphthalene for recovery, it reverted to incinerating larger quantities of naphthalene since 2003.

SIC 3728 (Aircraft parts and equipment, nec)

• One facility reported naphthalene in this industry sector. This facility reported significant increases for
2004 and again for 2005.

Exhibit 4.120 shows the national trends for how facilities managed naphthalene in 2001-2005.

Disposal: From 2001 to 2004, approximately 5 percent of naphthalene was disposed of. In 2005, the quantity
disposed of more than doubled primarily due to the generation of wastes (692,000 pounds) by the shutdown of a
facility in Michigan and the cleanup of a release (183,000 pounds) at a facility in Louisiana.

Energy Recovery: From 2001 to 2004, facilities used energy recovery to manage an average of approximately
5.1 million pounds or 46 percent of the naphthalene. In 2005, the quantity increased by approximately 1 million
pounds. A facility in Texas reported approximately a 1.2 million pound increase from demolition and
tank/releases cleanup efforts. A facility in Alabama reported an increase of approximately 148,000 pounds
from the clean-up and cleanout of tanks in preparation for demolition of the facility.

Treatment: In 2005, treatment of naphthalene increased by approximately 5.4 million pounds or 134 percent,
compared to the quantity treated in 2001. Significant increases of approximately 1.6 million pounds, 1.3
million pounds, and 2.5 million pounds were reported for 2002, 2004, and 2005, respectively. A facility in
Texas reported increases of approximately 286,000 pounds, 1.3 million pounds, and 2.4 million pounds for
these years, respectively - attributed to compliance with air pollution standards and a change in how material
sent to flaring was calculated.

Recycling: Compared to the quantity of naphthalene recycled in 2001, recycling increased by approximately

5.6	million pounds or 88 percent in 2005. The quantity has fluctuated, including an increase of approximately
19.4 million pounds in 2002, and decreases of approximately 7.2 million pounds and 7.3 million pounds in 2003
and 2005, respectively. A facility in Texas accounted for much of these fluctuations, reporting an increase of
19 million pounds for 2002 followed by decreases of approximately 7.4 million pounds, 3,5 million pounds, and

4.7	million pounds for 2003 to 2005.

Exhibit 4.121 shows how facilities, within the 10 industry sectors in which approximately 90 percent of this PC was reported for 2005, managed
naphthalene. Facilities in SIC 2865 (Cyclic crudes and intermediates) reported most of the naphthalene that was disposed of, primarily by facilities
being shut down and generating wastes from activities related to the clean-up and cleanout of tanks and processing of residuals. Facilities in SIC
2865 also reported approximately 35 percent of the naphthalene sent to energy recovery. Much of this quantity originated from the clean-up of
releases and cleanouts of tanks at facilities in Texas and Alabama.

Facilities in SIC 2911 (Petroleum refineries) and SIC 3479 (Metal coating and allied services) reported approximately 76 percent of the treatment
quantity, mostly onsite.

Facilities in three industry sectors: SIC 2911 (Petroleum Refining), SIC 2865 (Cyclic crudes and intermediates), and SIC 2869 (Industrial organic
chemicals, nec) reported approximately 95 percent of the naphthalene that was recycled in 2005.

For 2005, 40 facilities in 12 industry sectors reported they only used recycling to manage approximately
433,000 pounds of naphthalene. Ten facilities reported approximately 99 percent of this quantity (Exhibit
4.122). Of these ten facilities, two facilities, one each in SIC 2879 (Pesticides and agricultural chemicals, nec)
and SIC 5171 (Petroleum bulk stations and terminals) reported approximately 85 percent of the recycled only
quantity.
