Re: Development of the 2002 Degreasing Database from the 2002 NEI
Database

**1.0 Summary**

The cost and risk analyses for the proposed halogenated solvent cleaning
residual risk NESHAP were based on a 1999 degreasing database developed
primarily from the 1999 NEI database. After the proposal was developed a
final version of the 2002 NEI database was released. In response to
public comment and to ensure that the latest available information was
utilized, a new 2002 degreasing database was developed from the final
version of the 2002 NEI Database (Final Version 2, Dated 10-23-06) and
used as the basis for the final rule.

The 2002 degreasing database was developed by querying the 2002 NEI
database based on the following criteria:

-   Halogenated HAP Emissions (PCE, TCE, MC, TCA, CT, and Methyl
    Chloroform),

-   Degreasing Source Classification Codes (SCC),

-   Keywords in Process and Unit Descriptions, and

-   Facility Name and location.

Tables 1a and 1b summarize the 2002 degreasing database and compare it
to the 1999 database that was developed prior to proposal. Based on the
comparison of the 1999 and the 2002 degreasing databases it can be seen
that the population of degreasers decreased by about 8% and the
emissions of halogenated solvents from degreasers decreased by about 31%
overall. However, given the uncertainties associated with the
development of emission inventories, neither the 1999 nor the 2002 NEI
inventory should be considered as correct in an absolute sense or as
suggesting temporal trends in degreasing machine populations or
emissions. Rather, we consider them to be "snapshots" of the true
long-term inventory of emissions for this source category, each carrying
its own degree of uncertainty.

Section 2.0 of the memorandum describes in detail how the 2002
degreasing database was developed.

**2.0 Steps in the Development of the 2002 Degreasing Database**

The 2002 degreasing database was derived from the 2002 NEI database in a
logical step-wise fashion. Each of these steps is described in this
section and corresponds to a specific component of the database as it is
shown in the Access file. In the final step the different components of
the database, i.e., steps 1 to 8, were put together to form the complete
2002 degreasing database summarized in Table 1.

[STEP 1 -- Halogenated HAP]{.underline}

The Pollutant Code field of the 2002 NEI database was queried to obtain
emissions data for the halogenated solvents listed in Table 2. The
resulting data from the query on the halogenated solvents contained
31,091 tons of emissions in 88,059 records (includes 17,469 facilities
and 26,770 units). Since only halogenated solvent emissions are of
interest, these 88,059 records were used as the starting database for
all subsequent queries when developing the 2002 degreasing database.

+-----------------------+-----------------------+-----------------------+

[STEP 2 - Degreasing Source Classification Codes (SCC)]{.underline}

Not all units emitting halogenated HAP are degreasing units; therefore,
SCC data were used to identify degreaser units within the 88,059 records
of halogenated HAP data. Specifically, the SCC field of the halogenated
HAP data was queried for the 31 SCC codes shown in Table 3. The query
for these 31 SCC resulted in the identification of 1,648 records of
degreasing data. These data represent 973 facilities and 1,482 emission
units. The halogenated HAP emissions from these units are summarized in
Table 4.

[STEP 3 - Keyword searches on process and unit descriptors]{.underline}

To identify additional degreasing units the Unit Description and Process
Description fields were searched for the following keywords:
\"\*degreas\*\", \"\*clean\*\", \"\*web\*\", \"\*wash\*\", and
\"\*cold\*\". However, the version of the 2002 NEI Database that was
available (Final Version 2, Dated 10-23-06), did not contain the unit
description and process description fields. Therefore, the keyword query
was conducted on an earlier version of the 2002 NEI database (5-31-06
version). Once the facilities were identified in this earlier version
the facility registry identifier was used to identify the facilities in
the 10-23-06 version of the 2002 NEI Database.

A review of the Unit Descriptions and Process Descriptions showed that
degreasing as well as non-degreasing units were captured. Non-degreasing
units included dry cleaning units, web printing, wipe cleaning, etc.
After removing the non-degreasing units from the keyword search there
were 160 records remaining. The 160 records represented 83 facilities
and 134 units. The halogenated HAP emissions from these units are
summarized in Table 5.

[STEP 4 -- Combination of Step 2 and 3]{.underline}

The data identified in Steps 2 and 3 were combined resulting in 1,808
records, 1,036 unique facilities, and 1,616 unique units.

[STEP 5 -- Web Cleaning Machines]{.underline}

The data compiled in Step 4 were checked to ensure that all known
facilities (as identified primarily from comment letters on the 1994
NESHAP) performing web cleaning were captured. Table 6 shows each web
cleaning facility and the result of the 2002 NEI search. Of the ten web
cleaning facilities 6 were captured in the SCC and keyword searches. Two
facilities were not captured based on SCC or keyword, but were found in
2002 NEI using a facility name search. The data for these two facilities
were added to the degreasing database (3 units, 57.9 tons of Methylene
Chloride, 17.1 tons of Trichloroethylene). The American Safety Razor
facility in Verona, VA and the LTV-Copperweld facility in Fayetteville,
TN were not found in the 2002 NEI database.

[STEP 6 - Searches on Additional SCC Codes Identified in Keyword
Searches and from Other Known Degreasing Facilities]{.underline}

To identify additional degreasing units a closer look was taken at
identifying additional SCC that could be used to further develop the
database. The following approaches were used to identify additional SCC.

1.  We looked at the top 50 (on the basis of magnitude of emissions) SCC
    codes emitting halogenated HAP as reported in the 2002 NEI database
    (Appendix Table A1).

2.  We looked at the SCC for the units identified based on the keyword
    search of process descriptors and unit descriptors (Appendix Table
    A2).

3.  We looked at the SCC for units at web facilities and other
    facilities identified through public comments.

4.  A search of the full list of SCC codes was conducted based on
    keywords, such as, "cleaning" and "degreasing." Several additional
    SCC were identified.

5.  We evaluated adding SCC 49099999 (Petroleum and Solvent Evaporation,
    Organic Solvent Evaporation, Miscellaneous Volatile Organic
    Compounds, Process and Solvent to be identified in Comments) which
    is a generic SCC. In the 2002 NEI there are 126 records with a total
    of 222 tons of halogenated HAP emissions that are designated with
    SCC 49099999. Of the 222 tons, 109 tons (49%) were already
    identified as degreasing units. Based on the unit and process
    descriptions we determined that another 67 tons (30%) are definitely
    not degreasing units. For the remaining 47 tons (21%) there is not
    enough data to determine whether they are degreasers or not.
    Therefore, these units were not added to the degreasing database.

Table 7 shows the additional SCC that were used to search the 2002 NEI
Database to identify degreasers. As a result of the search for
additional SCC 119 records, representing 91 units and 55 facilities,
were identified. The halogenated HAP emissions from these facilities are
shown in Table 8.

[STEP 7 -- Check for Commenters]{.underline}

The degreasing database was checked to ensure that all of the facilities
conducting degreasing that submitted public comments were captured. In
addition, we checked to make sure that the magnitude of emissions
captured in NEI for these facilities was comparable to the emissions
values cited in the comment letters. Table 9 shows the facilities that
were evaluated as part of this analysis. This analysis resulted in the
addition of 6 records representing 6 units. The emissions that were
added to the database are shown in Table 10.

                             were coded with a different SCC. The
                             emission unit ID field indicates that these
                             are in-line cleaning machines.

                             is required. PPG did not specify a plant
                             location for their degreasing activities.
                             Five PPG facilities were found with
                             halogenated solvent emissions.

  Kodak, NY                  Found 44 units at this location with
                             halogenated HAP emissions of 434 tons. These
                             were not added to the degreasing database
                             because the Kodak comment letter indicates
                             that they only have a small R&D cleaner at
                             that location. Therefore, the 44 units must
                             be something other than degreasers.

[STEP 8 -- Search for 96 Facilities from the Preliminary Risk Test and
Compilation of Steps]{.underline}

The degreasing database developed to this point was checked to determine
whether the 96 degreasing facilities from the preliminary risk test were
included. The preliminary risk test facilities were originally
identified from compliance reports submitted to the States in 1998.
Therefore, this data is from a different source than NEI and is somewhat
outdated.

The results of our search for the 96 preliminary risk test facilities
are as follows (See Table A3):

-   28 facilities were already captured by our 2002 degreasing database.

-   7 facilities were found in 2002 NEI with halogenated HAP emissions.
    These 7 facilities represent 10 records, 10 units, with 71.8 tons of
    TCE emissions. These data were added to the degreasing database and
    are shown in Table 11.

-   12 facilities were found in 2002 NEI but did not have halogenated
    HAP emissions reported.

-   49 facilities were not found in the 2002 NEI. In addition, we
    checked the Toxics Release Inventory for these facilities and none
    were found to have reported halogenated HAP emissions for 2002.
    Therefore, we assumed that these facilities were not conducting
    halogenated solvent cleaning any longer.

Table 12 summarizes the records, units, facilities, and halogenated HAP
emissions contained in the 2002 degreasing database by Step and Total.
The 1,080 facilities contained in the degreasing database were used as
the basis for the cost and risk analyses conducted for the final rule.
