National Biennial RCRA Hazardous Waste Report: Based on 1999 Data
EXECUTIVE SUMMARY
The United States Environmental Protection Agency (EPA), in partnership with the States1, biennially
collects information regarding the generation, management, and final disposition of hazardous wastes
regulated under the Resource Conservation and Recovery Act of 1976 (RCRA), as amended. The purpose
of The National Biennial RCRA Hazardous Waste Report (Based on 1999 Data) is to communicate the
findings of EPA's 1999 Biennial Report (BR) data collection efforts to the public, government agencies, and
the regulated community.2 The Report consists of six volumes:
The Executive Summary provides an overview of national hazardous waste generation and
management practices;
The National Analysis presents a detailed look at waste-handling practices in the EPA
Regions, States, and largest facilities nationally, including (1) the quantity of waste generated,
managed, shipped and received, and imported and exported between States and (2) the
number of generators and managing facilities;
The State Summary Analysis provides a two-page overview of the generation and
management practices of individual States;
The State Detail Analysis is a detailed look at each State's waste handling practices, including
overall totals for generation, management, and shipments and receipts, as well as totals for the
largest fifty facilities;
The List of Large Quantity Generators identifies every hazardous waste generator in the
United States that reported itself to be a large quantity generator in 1999; and
The List of Treatment, Storage, and Disposal Facilities identifies every hazardous waste
manager in the United States that reported itself to be a treatment, storage, or disposal facility
in 1999.
The term "State" includes the District of Columbia, Puerto Rico, Guam, the Navajo Nation, the Trust Territories, and the Virgin Islands, in
addition to the 50 United States.

Some respondents from the States of Georgia and Connecticut submitted Confidential Business Information (CBI) pursuant to ยง40 CFR
260.2(b). While not included in any public database, CBI has been incorporated into the Executive Summary and National Analysis volumes
of this Report wherever possible. Where CBI has been omitted from these volumes, a footnote has been provided.
Exclusion of wastewater from the 1999 National Biennial Report will make cursory comparisons of the 1999 National Biennial Report to
National Biennial Reports prior to 1997 misleading. Refer to Executive Summary (ES-2) for a complete explanation.

National Biennial RCRA Hazardous Waste Report: Based on 1999 Data
RCRA HAZARDOUS WASTE
Throughout this Report, the term RCRA hazardous waste refers to solid waste assigned a Federal
Hazardous Waste Code and regulated by RCRA. Some States elect to regulate wastes not regulated by
EPA; these wastes are assigned State Hazardous Waste Codes and are not included in this Report. The
reader can find more detailed explanations in the RCRA Orientation Manual
(http://www.epa.gov/epaoswer/general/orientat/) and in the Code of Federal Regulations in 40 CFR Parts
260 and 261 (http://www.epa.gov/docs/epacfr40/chapt-l.info/subch-l.htm). Please refer to Appendix D of the
National Analysis volume for a complete list of EPA Hazardous Waste Codes used by the regulated
community for their 1999 Biennial Report submissions. Details about the information submitted by the
regulated community can be found in the 1999 Hazardous Waste Report Instructions and Forms
(http://www.epa.gov/epaoswer/hazwaste/data/brs99/forms.htm).
WASTEWATER EXCLUSION LOGIC USED FOR NATIONAL REPORTING
Wastewaters are defined for biennial reporting as wastes that have a particular form and/or are
managed on-site or off-site in treatment systems typically used to manage wastewater. All wastes bearing
one of the following wastewater Form Codes (B101-102; B105, B110-116) and/or System Type Codes
(M071-079; M081-085, 089; M091-094, 099; M121-125, 129; M134-136) are excluded from the National
Report data and the 1999 National Biennial Report, with one exception: wastewaters managed by
System Type Code M134 (Deepwell/Underground Injection) are included in the 1999 National Biennial
Report. Refer to Appendix B and C of the National Analysis volume for complete descriptions of the System
Type Codes and Form Codes referenced above.
In biennial report cycles prior to 1997, the PS Form was used to separate and exclude from the
National Report data all wastes going to on-site treatment systems exempt from RCRA permitting
requirements. For the 1999 National Biennial Report, EPA included all non-wastewater data and
excluded all wastewater data. The wastewater data was excluded regardless of whether the wastes
were managed in RCRA permitted systems prior to management in on-site or off-site treatment
systems exempt from RCRA permitting requirements. This is significant, because historically EPA has
included only those wastes managed in units subject to RCRA permitting requirements in the National
Biennial Reports. EPA does not believe the inclusion of all non-wastewaters will distort the RCRA hazardous
waste management picture presented in this Report, because only a small volume of non-wastewaters are
managed in treatment systems exempt from RCRA permitting requirements.
Exclusion of wastewater from the 1999 National Biennial Report will make cursory comparisons of the 1999 National Biennial Report to
National Biennial Reports prior to 1997 misleading. Refer to Executive Summary (ES-2) for a complete explanation.

National Biennial RCRA Hazardous Waste Report: Based on 1999 Data
RCRA HAZARDOUS WASTE GENERATION
RCRA hazardous waste generation information is obtained from data reported by RCRA large
quantity generators (LQGs). A generator is defined as a Federal large quantity generator if:
the generator generated in any single month 1,000 kg (2,200 pounds or 1.1 tons) or more of
RCRA hazardous waste; or
the generator generated in any single month, or accumulated at any time, 1 kg (2.2 pounds) of
RCRA acute hazardous waste; or
the generator generated, or accumulated at any time, more than 100 kg (220 pounds) of spill
cleanup material contaminated with RCRA acute hazardous waste.
All generators that reported LQG status in 1999 are required to provide EPA with 1999 waste
generation and management information. It is important to note that the LQGs identified in this Report have
been included based on the most current information made available to EPA by the States. Both EPA and
the States have made a significant effort to ensure the accuracy of this data. However, the LQG counts may
include generators that, when determining whether they were LQGs, used a lower State-defined threshold
for LQGs, counted wastes regulated only by their States, or counted wastes exempt from Federal regulation.
To help provide a more accurate picture of hazardous waste generation in the United States, EPA
requests specific waste generation information from LQGs. For each RCRA hazardous waste generated,
LQGs are required to provide a waste description, the applicable Federal Hazardous Waste Codes that most
accurately represent the waste generated, and the quantity of waste generated.
In 1999, 20,083 LQGs reported they generated 40 million tons of RCRA hazardous waste. When
comparing the 1997 National Biennial Report with the 1999 Report, the number of LQGs decreased by 233,
and the quantity of hazardous waste generated decreased by 650 thousand tons or 1.5%. Beginning with
the 1997 BR cycle and continuing with the 1999 BR cycle, the generation of wastewater is excluded from the
national reporting logic. For a more detailed description of the wastewater exclusion, please refer to the
section of the Executive Summary entitled "Wastewater Exclusion Logic Used for National Reporting." The
wastewater exclusion will make cursory comparisons between the 1999 National Biennial Report and
National Reports prior to 1997 misleading.
Exclusion of wastewater from the 1999 National Biennial Report will make cursory comparisons of the 1999 National Biennial Report to
National Biennial Reports prior to 1997 misleading. Refer to Executive Summary (ES-2) for a complete explanation.

National Biennial RCRA Hazardous Waste Report: Based on 1999 Data
As identified in Exhibit 1, the five (5) States which contributed most to the national hazardous waste
generation total in 1999 were Texas (14.9 million tons), Louisiana (4.4 million tons), Illinois (2.9 million tons),
Tennessee (2.2 million tons), and Ohio (1.6 million tons). Together, the LQGs in these States accounted for
65% of the national total quantity generated.

National Biennial RCRA Hazardous Waste Report: Based on 1999 Data
RCRA HAZARDOUS WASTE MANAGEMENT
RCRA hazardous waste management information is obtained from data reported by active,
permitted RCRA treatment, storage, or disposal facilities (TSDs). A TSD is defined as any facility which
treats, stores, or disposes of RCRA hazardous waste, regardless of the quantity managed. Only wastes that
were treated or disposed of in 1999 are included in the management quantities in this Report. Wastes
generated and subsequently stored in 1999 are not included in the management quantities in this Report. In
addition, the management quantities in this Report do not include waste from transfer facilities (System
Code M141).
To help provide a more accurate picture of hazardous waste management practices in the United
States, EPA requests specific waste management information from TSDs. For each RCRA hazardous
waste managed, TSDs are required to provide the quantity of waste managed and the System Type Code
which represents the management method used to manage the waste.
It is important to note that the total quantity of RCRA hazardous waste generated is less than the
total quantity managed. Some of the reasons for this variance include: wastes generated during non-
reporting years but shipped and treated or disposed during a reporting year and wastes received for
management from generators in foreign countries.
In 1999, 1,575 TSDs reported they managed 26.3 million tons of RCRA hazardous waste. Of the
1,575 facilities, 1,049 were storage-only facilities. When comparing the 1997 National Biennial Report with
the 1999 Report, the number of TSDs decreased by 450, and the total quantity of hazardous waste
managed decreased by 11.4 million tons or 30%. Beginning with the 1997 BR cycle and continuing with the
1999 BR cycle, the management of wastewater is excluded from the national reporting logic. For a more
detailed description of the wastewater exclusion, please refer to the section of the Executive Summary
entitled "Wastewater Exclusion Logic Used for National Reporting." The wastewater exclusion will make
cursory comparisons between the 1999 National Biennial Report and National Reports prior to 1997
misleading.
As identified in Exhibit 2, the five (5) States whose TSDs managed the largest quantities of
hazardous wastes were Texas (5.8 million tons), Louisiana (4.2 million tons), Florida (2.8 million tons),
Kansas (2.3 million tons), and Ohio (1.7 million tons). The TSDs in these five (5) States account for 64% of
the national management total.
Exclusion of wastewater from the 1999 National Biennial Report will make cursory comparisons of the 1999 National Biennial Report to
National Biennial Reports prior to 1997 misleading. Refer to Executive Summary (ES-2) for a complete explanation.

National Biennial RCRA Hazardous Waste Report: Based on 1999 Data
RCRA HAZARDOUS WASTE SHIPMENTS AND RECEIPTS
RCRA hazardous waste shipment information is obtained from data reported by both RCRA LQGs
and RCRA TSDs. To help provide a more accurate picture of hazardous waste shipments in the United
States, EPA requests specific shipment information. For each waste shipped, LQGs and TSDs are required
to provide a waste description, the applicable Federal Hazardous Waste Codes, the quantity of waste
shipped, and the EPA Identification Number of the receiving facility. All RCRA non-wastewater shipments
reported by RCRA LQGs and TSDs are included in the waste shipment quantities in this Report, even if the
waste was shipped to a transfer facility. In some instances, waste is transferred within a physical location
that has more than one EPA Identification Number. These waste transfers are treated as shipments.
RCRA hazardous waste receipt information is obtained from data reported by RCRA TSDs. To help
provide a more accurate picture of hazardous waste receipts in the United States, EPA requests certain
receipt information from TSDs. For each waste received, TSDs are required to provide a waste description,
the applicable Federal Hazardous Waste Codes, the quantity of waste received, and the EPA Identification
Number of the facility from which the waste was received. For each received waste which is subsequently
managed, TSDs are required to provide the System Type Code which represents the management method
used to manage the waste. All RCRA non-wastewater receipts reported by RCRA TSDs are included in the
waste receipt quantities in this Report, even if the waste was received from a transfer facilitiy.
RCRA hazardous waste export quantities include wastes generated in one State and shipped to a
receiver in a different State. Exports are calculated from information provided by waste shippers. RCRA
hazardous waste imports include all wastes received by a State which differs from the State of origin. RCRA
hazardous waste imports are calculated from information provided by RCRA TSDs.
In 1999, 17,914 shippers reported shipping 8.1 million tons of RCRA hazardous waste. When
comparing the 1997 National Biennial Report with the 1999 Report, the number of shippers decreased by
115, and the quantity of waste shipped increased by 817 thousand tons or 11%. Beginning with the 1997
BR cycle and continuing with the 1999 BR cycle, the shipment of wastewater is excluded from the national
reporting logic. For a more detailed description of the wastewater exclusion, please refer to the section of
the Executive Summary entitled "Wastewater Exclusion Logic Used for National Reporting." The wastewater
exclusion will make cursory comparisons between the 1999 National Reports and National Reports prior to
1997 misleading.

National Biennial RCRA Hazardous Waste Report: Based on 1999 Data
Of the 8.1 million tons of RCRA hazardous waste shipped in 1999, 5.7 million tons of waste were
exported from the State in which they were generated to other States. When comparing the 1997 National
Biennial Report with the 1999 Report, the quantity of waste exported increased by 1.3 million tons or 30%.
Beginning with the 1997 BR cycle and continuing with the 1999 BR cycle, the export of wastewater is
excluded from the national reporting logic. For a more detailed description of the wastewater exclusion,
please refer to the section of the Executive Summary entitled "Wastewater Exclusion Logic Used for
National Reporting." The wastewater exclusion will make cursory comparisons between the 1999 National
Biennial Report and National Reports prior to 1997 misleading.
In 1999, 499 TSDs reported receiving 6.6 million tons of RCRA hazardous waste. When comparing
the 1997 National Biennial Report with the 1999 Report, the number of TSDs receiving waste decreased by
44, and the quantity of waste received decreased by 1.4 million tons or 18%. Beginning with the 1997 BR
cycle and continuing with the 1999 BR cycle, the receipt of wastewater is excluded from the national
reporting logic. For a more detailed description of the wastewater exclusion, please refer to the section of
the Executive Summary entitled "Wastewater Exclusion Logic Used for National Reporting." The wastewater
exclusion will make cursory comparisons between the 1999 National Biennial Report and National Reports
prior to 1997 misleading.
Of the 6.6 million tons of RCRA hazardous waste received in 1999, 3.7 million tons of waste were
imported from other States. When comparing the 1997 National Biennial Report with the 1999 Report, the
quantity of waste imported decreased by 242 thousand tons or 6%. Beginning with the 1997 BR cycle and
continuing with the 1999 BR cycle, the import of wastewater is excluded from the national reporting logic.
For a more detailed description of the wastewater exclusion, please refer to the section of the Executive
Summary entitled "Wastewater Exclusion Logic Used for National Reporting." The wastewater exclusion will
make cursory comparisons between the 1999 National Report and National Reports prior to 1997
