MEMORANDUM	

TO:		Patricia Mercer, EPA

FROM:	Maribelle Rodríguez, Mike Hartley, and Earl Harris

SUBJECT:	College and University Large Quantity Generators in 2001; 

Work Assignment Number 3-33, Contract Number 68-W-02-006

Under the referenced work assignment, ICF identified college and
university (C/U) large quantity generators (LQGs) in 2001 and estimated
the quantity of hazardous waste generated by these sites.  Section 1 of
this memorandum describes the methodology used to identify and collect
data on C/U LQGs.  Section 2 summarizes information on the number of C/U
LQGs and the quantity of hazardous waste generated by these sites.

Please do not hesitate to contact Maribelle at (703) 218-2508 with
questions or comments.

1.	Methodology

To identify C/U LQGs in 2001 and estimate the quantity of hazardous
waste generated by these sites, ICF undertook the following steps:

Step 1:  Identify C/U LQGs in 2001  

To identify C/U LQGs in 2001, ICF referred to the Site Identification
(ID) Forms of the 2001 Biennial Report (BR).  The Site ID Form contains
basic waste handler information (e.g., EPA ID number, site name, Federal
generator status).   

Based on Federal generator status information reported in the Site ID
Forms, we identified all LQGs in 2001.  For these sites, we extracted
the following information from the Site ID Forms and used it to create a
2001 C/U LQG database:

EPA ID number;

Site name;

Address;

EPA Region;

·	Primary North American Industrial Classification System (NAICS) code;

·	Secondary NAICS code(s);

Federal generator status (i.e., LQG); and

·	Indicator of whether the site treats, stores, or disposes of
hazardous waste.

Sites represented by primary NAICS codes 6112 through 6116 were
categorized as four-year, two-year, or vocational schools.  Sites
represented by primary NAICS code 622 were categorized as hospitals. 
Sites represented by any other primary NAICS code were excluded from the
rest of the analysis.

Exhibit 1 provides a description of the NAICS codes used in this
analysis, as well as the corresponding SIC codes.  The exhibit also
indicates how the NAICS codes were used to categorize LQGs by type of
institution.

For sites categorized as four-year, two-year, or vocational schools, ICF
reviewed the list of site names to identify C/Us that have an art
program and/or a medical school.  In conducting this review, ICF
referred to the following two references:

The Art School and Program Directory, which was developed by
ArtSchools.com; and 

List of Medical Schools of the U.S. and Canada, which was developed by
the Association of American Medical Colleges. 

For sites categorized as hospitals, ICF reviewed the list of site names
to identify hospitals affiliated with a C/U.  If a hospital is
affiliated with a C/U (e.g., Howard University Hospital), the site was
considered a C/U LQG.  If a hospital is not affiliated with a C/U (e.g.,
Kaiser Permanente Medical Center), the site was excluded from the rest
of this analysis.  Note that, in determining whether a hospital is
affiliated with a C/U, we referred to List of Medical Schools of the
U.S. and Canada, which was developed by the Association of American
Medical Colleges.  If this reference did not address our need, we made a
determination based on information obtained through minimal research
(i.e., a simple Web search) or used our own judgment. 

Step 2:  Compile Information on Hazardous Waste Generated by C/U LQGs in
2001 

Once the C/U LQGs were identified, ICF compiled waste stream data
reported in Generation and Management (GM) Forms of the 2001 BR.  The GM
Form includes information on hazardous waste streams generated and
managed on site or sent off site for management.

For each hazardous waste stream generated by a C/U LQG, we compiled the
following information:

Quantity of waste generated;

Form code;

Source code;

RCRA radioactive mixed; 

EPA hazardous waste codes representing the hazardous waste;

Waste type;

Waste description;

Indicator of whether the waste is a laboratory waste;

EPA ID of the facility managing the waste stream;

Name of the facility managing the waste stream;

Code of management method used; and

Quantity of waste managed using management method code.

The above data were included in the 2001 C/U LQG database developed
under Step 1.  

Waste types were assigned to each waste stream based on the EPA
hazardous waste codes representing it.  For information on the waste
stream classification scheme used in this analysis, refer to Attachment
A.

ICF notes that, for purposes of this analysis, a waste was considered a
laboratory waste if the BR waste description contained the word
“lab.”

Step 3: Eliminate Remediation Waste Streams from the 2001 C/U LQG
Database

After compiling the waste stream information, ICF identified and
eliminated remediation waste streams from the 2001 C/U LQG database. 
For purposes of this analysis, a waste was considered a remediation
waste if it was represented by the BR source code G41-G49, or the BR
waste description contained the word “remediation.”

Step 4:  Estimate Quantity of Hazardous Waste Generated by C/U LQGs in
2001 

To estimate the total quantity of hazardous waste generated by C/U LQGs
in 2001, ICF added up the quantity of hazardous waste generated by each
of these sites in 2001. 

2.	Data Summaries

Exhibit 2 shows the number of C/U LQGs and the quantity of hazardous
waste generated by these LQGs in 2001, by type of institution (e.g.,
four-year school), industry sector, and waste type.  It also shows the
total number of LQGs (i.e., 365) and the quantity of hazardous waste
generated by these LQGs in 2001 (i.e., 34,563 tons).

Exhibit 3 shows the number of C/U LQGs that generated laboratory waste
in 2001 and the quantity of laboratory waste generated by these LQGs, by
type of institution, industry sector, and waste type.  It also shows the
total number of LQGs (i.e., 266) and the quantity of laboratory waste
generated by these LQGs in 2001 (i.e., 3,109 tons).  ICF notes that, for
purposes of this analysis, a waste was considered a laboratory waste if
the BR waste description contained the word “lab.”

Exhibit 4 shows the number of LQGs at C/Us with art programs and the
quantity of hazardous waste generated by these LQGs in 2001, by type of
institution, industry sector, and waste type.  It also shows the total
number of LQGs (i.e., 239) and the quantity of hazardous waste generated
by these LQGs in 2001 (i.e., 7,167 tons).  ICF notes that the BR does
not contain a data element that indicates positively whether a hazardous
waste stream was generated as a result of art-related activities.  Thus,
the exhibit shows data for all hazardous waste generated by LQGs at C/Us
with art programs.  The reader should not assume, however, that all of
this waste quantity is related to art activities.  In fact, some
percentage of this waste might come from LQGs within the art programs. 

Exhibit 5 shows the number of LQGs at C/Us with medical schools and the
quantity of hazardous waste generated by these LQGs in 2001, by type of
institution, industry sector, and waste type.  It also shows the total
number of LQGs (i.e., 66) and the quantity of hazardous waste generated
by these LQGs in 2001 (i.e., 1,475 tons).  ICF notes that the BR does
not contain a data element that indicates positively whether a hazardous
waste stream was generated as a result of medical school activities. 
Thus, the exhibit shows data for LQGs whose site names refer to a
medical school or to a hospital affiliated with a C/U (i.e., a
university hospital).

a  The Biennial Report does not contain a data element that indicates
positively whether a hazardous waste stream was generated as a result of
medical school activities.  Thus, the exhibit shows data for LQGs whose
site names refer to a medical school or to a hospital affiliated with a
C/U (i.e., a university hospital).

b  Exhibit does not include data on remediation wastes.  For purposes of
this analysis, a waste was considered a remediation waste if it was
represented by the Biennial Report source code G41-G49, or the Biennial
Report waste description contained the word “remediation.”

c  An LQG may generate more than one type of waste.  Thus, the number of
LQGs is not additive.

d  Based on total quantity of waste generated by C/U LQGs in 2001, i.e.,
34,563 tons.

Waste Stream Classification

Waste Stream Classification

As described in Step 2 of this memorandum, ICF has attempted to describe
the waste streams of C/U LQGs based on their waste codes.  If one waste
code was reported for a given waste stream, ICF relied on that code to
describe the waste (e.g., a waste stream with only a D004 waste code was
described as “inorganic (metal) waste”).

Note that many hazardous waste streams include two or more waste codes. 
For these waste streams, ICF developed a simplifying approach for
describing them.  Specifically, ICF used the classification scheme in
Exhibit A-1 to classify waste codes as either “primary” or
“secondary” codes.  Primary waste codes are codes that, in ICF’s
professional judgment, more accurately describe the type of waste in
comparison with secondary codes.  

ICF used primary codes to describe waste streams with two or more waste
codes.  For example, as shown in the exhibit, a waste stream containing
F001 and D001 waste codes was described in this memorandum as a “spent
solvent.”
