Inventory Update Reporting (IUR) Technical Support Document

Replacement of 5-digit NAICS Codes with Industrial Sector (IS) Codes

Draft

U.S. Environmental Protection Agency

Office of Pollution Prevention and Toxics

1201 Constitution Ave., NW 

Washington, DC

October 2009Executive Summary

The 2006 IUR collection was the first time that EPA collected
information on the industrial processing and use of organic chemical
substances from manufacturers and importers producing 300,000 pounds or
more of an organic chemical substance at a single site (Form U Part
III).  For 2006, respondents provided the five-digit North American
Industry Classification System (NAICS) Code to describe the setting in
which industrial processing and use occurred.  

EPA examined the 2006 IUR collection and found respondents submitted
over 340 unique five-digit NAICS codes.  Some of the reported codes were
invalid and could not be related to any industrial setting.  Other
persons left the NAICS code blank or reported that it was not known or
readily obtainable.  EPA uses the five-digit NAICS code in combination
with the industrial function code and process and use code to define a
use scenario.  The large number of possible three-code combinations has
made it more difficult for EPA to group and assess chemicals. EPA is
proposing to replace the NAICS code with a new code, Industrial Sector
(IS), to describe the industrial setting.

EPA developed the 48 new IS codes by examining the results of the 2006
IUR data collection, reviewing the codes used by the European Union for
the Registration, Evaluation, Authorisation and Restriction of Chemical
Substances (REACH) program, and considering EPA’s use of the IUR data.
The proposed IS codes divide the entire range of NAICS codes into a set
of 48 segments covering broader ranges of activities.  When the
reporting for a single NAICS code was frequent, the five-digit NAICS
code was replaced by a corresponding IS code.  When the reporting of
NAICS codes was very infrequent and the exposure scenario was likely to
be the same for a range of NAICS codes, a single IS code replaced all
NAICS codes beginning with the same digit, i.e. a single IS code
replaces all NAICS codes beginning with the number five which indicates
services.  

Replacing the NAICS codes with a new IS code will have benefits for both
EPA and respondents. The new codes will sort the chemicals into broader
categories thus reducing the reporting burden on respondents since they
do not need to determine a specific five-digit NAICS code.  EPA
anticipates that using the IS categories will reduce the number of
erroneous responses, may reduce the number of confidential business
information (CBI) claims, and may reduce the number of unique chemical
exposure scenarios that EPA will need to develop for priority setting
and risk screening programs.

Appendix A – Additional InformationBackground

This section provides background information on the IUR reporting
requirements, the results of the 2006 IUR data collection, and
information on the European Union’s chemical use data collection.  EPA
used this information to develop new Industrial Sector (IS) codes that
will replace the five-digit NAICS codes in the 2011 IUR reporting.

2006 IUR Reporting Requirements

The 2006 IUR collection was the first time that EPA collected
information on the industrial processing and use of organic chemical
substances from manufacturers producing 300,000 pounds or more of an
organic chemical substance at a single site (Part III of IUR Form U). 
This reporting was in addition to the production volume information
collected in previous reporting cycles.  The industrial processing and
use information is collected using three reporting codes which taken
together define a potential exposure scenario:

Type of Process or Use (P/U) Code – Defines the operations in which
the chemical is used.

PC: Processing as a reactant

PF:  Processing – incorporation into formulation, mixture, or reaction
product

PA: Processing – incorporation into article

PK:  Processing – repackaging

U:  Use – non-incorporative activities

North American Industry Classification System (NAICS) Code – Codes
published by the Office of Management and Budget (OMB) to describe the
industry in which chemical processing and use may occur.  IUR requires
submitters to report a five-digit NAICS code. 

Industrial Function Category (IFC) Code – Defines the function of the
chemical (e.g., adhesive, flame retardant, solvent).  The 2006 IUR
utilized 33 IFC codes. Additional information on the 2011 IFC codes can
be found in Overview of Harmonized U.S.-Canada Industrial Function and
Consumer and Commercial Product Codes for Chemical Inventory Reporting,
June 2009, prepared by U.S. EPA, Health Canada, and Environment Canada.

EPA uses this information to perform screening-level exposure
characterizations for industrial settings.

2006 IUR Statistics

Based on information from the NAICS Web site (  HYPERLINK
"http://www.census.gov/naics/2007/index.html" 
http://www.census.gov/naics/2007/index.html ), there are 724 possible
five-digit NAICS codes that respondents can enter in Part III of the IUR
Form U.  Two-digit NAICS codes represent general sectors, with
additional digits added to further refine the description of the
industry.  An example of the hierarchy for chemical manufacturing is
listed below:

31 – 33: Manufacturing

325: Chemical Manufacturing

3251: Basic Chemical Manufacturing

32513:  Synthetic Dye and Pigment Manufacturing

325131: Inorganic Dye and Pigment Manufacturing

Submissions to the 2006 IUR included over 340 unique five-digit NAICS
codes.  EPA uses the NAICS code to aid in developing exposure scenarios.
Many of the 340 NAICS codes reported are from similar industries that
would have similar exposure scenarios. The large number of NAICS codes
reported makes it more difficult to group chemicals.  

The three-code combination of P/U, NAICS, and IFC is needed to fully
describe the industrial processing and use activity; therefore, there
are a large number of possible three-code combinations.  The 2006 IUR
three-code combinations allow almost 120,000 degrees of freedom. 
Although not all of the NAICS codes are applicable to chemical
manufacturing and processing, the 2006 IUR database has over 2,300
unique combinations of P/U, NAICS, and IFC.  The large number of unique
combinations increases the difficulty and time required to sort and
classify chemicals since EPA would either need to develop exposure
scenarios for each unique combination or determine which three-code
combinations have similar exposure scenarios and can be grouped
together.  

EPA reviewed information on the extent of confidential business
information (CBI) claims for the industrial processing and use
information. When considering the three-code combination, which is
needed to fully evaluate the exposure scenario, EPA considers the
combination CBI if any of the three codes were claimed CBI.  The 2006
IUR database had the following CBI claims for the individual data
elements:

P/U – 4,019 of 15,151 entries were claimed CBI (27 percent);

IFC – 4,190 of 15,151 entries were claimed CBI (28 percent);

NAICS – 4,476 of 15,151 entries were claimed CBI (30 percent);

When evaluating the CBI status of the three-code combination (at least
one code in the reported combination was CBI), approximately 80 percent
were claimed CBI.  Note that EPA did not evaluate this by chemical; one
chemical may have a CBI three-code combination but the same three-code
combination may be reported as non-CBI for another chemical.  

  REF _Ref242008194 \h  Table 1  shows the top 25 NAICS codes reported
in the 2006 IUR and Table A-1 in Attachment A contains the full list. 
The IUR database contains 15,151 potential NAICS code entries (number of
reports in database version 1.02).  As shown in the tables, the chemical
manufacturing codes (325 series) were reported most frequently.  Some
responses reported for NAICS were invalid or did not provide useful
information:

Not Readily Obtainable – Since respondents were submitting information
for downstream processing and use, the IUR requirements allowed
respondents to enter ‘NRO’ if they did not have readily obtainable
information on NAICS code.  NRO was reported 693 times.

Blank – There were 127 submissions that left NAICS code blank.

Invalid Entries – The IUR database contained several NAICS codes that
were not listed on the NAICS Web site (see Table A-1).  There were 274
invalid entries.

Invalid, blank, and NRO entries do not provide use information and
account for over six percent of the NAICS code responses.

European Union Reporting Codes

EPA reviewed information on the European Union’s (EU) Registration,
Evaluation, Authorisation and Restriction of Chemical Substances (REACH)
program to compare the reporting codes used in REACH to EPA’s IUR
reporting codes.  The following documents describe the codes and
categories that are used to describe chemical processing and use under
REACH:

 “Technical Guidance Document for Preparing the Chemical Safety
Assessment, Part D” dated November 26, 2007 (Guidance Document).

“Environmental Exposure Assessment: Revision of the Use Pattern
Description” dated July 30, 2008 (Use Pattern Revision Document). 

“Guidance on Information Requirements and Chemical Safety
Assessment” Chapter R12: Use Descriptor System, May 2008 (Use
Descriptor Document). 

The EU’s use descriptor system is designed such that codes can be
linked to a pre-defined environmental release category (ERC) or used in
a Tier 1 exposure model (e.g., European Commission on Ecotoxicology and
Toxicology (ECETOC) Targeted Risk Assessment model (TRA) or Consumer
Exposure model developed by the Netherlands (ConsExpo)).  According to
the Guidance Document, the use descriptors can help structure and group
the identified uses in a sensible way for exposure scenario building and
exposure estimation and support consistency and harmonized information
across markets. 

The EU system uses a Sector of Use (SU) code to provide information on
the industrial sector in which a chemical is used. The sector of use is
based on the EU’s NACE category system which is analogous to the U.S.
NAICS codes.  NACE codes are similar to NAICS codes in that there is a
hierarchy to the numbering system.  For example, the beginning of the
hierarchy for the agriculture, forestry, and fishing NACE code is listed
below:

A. - Agriculture, forestry and fishing; 

A1. - Crop and animal production, hunting and related service
activities;

A1.1. - Growing of non-perennial crops; and,

A1.1.1 - Growing of cereals (except rice), leguminous crops and oil
seeds.

The SU codes are defined similarly as the NACE codes except SU codes
typically only use the first or second levels of the hierarchy.  The EU
defined SU codes corresponding to second or third level NACE codes for
industries that may require additional detail.  The codes also group
similar NACE codes together.  Table A-2 lists the EU SU codes.  The EU
documents provide a crosswalk between SU and NACE codes.  

Examples:

SU 1 Agriculture, Forestry, and Fishing – Uses top level of NACE
hierarchy (NACE Code A);

SU 4 Manufacture of Food Products – Uses second level of NACE
hierarchy to provide additional details (NACE Code C10).  The top level
for this category (NACE C) is defined as manufacturing;

SU8 Manufacture of Bulk, Large Scale Chemicals (including petroleum
products) – This category could include NACE codes C19 - Manufacture
of coke and refined petroleum products and NACE code C20 - Manufacture
of chemicals and chemical products.

The EU system also defines two categories that can be used if one of the
23 defined codes is not applicable:

SU 0.1 – Other activity related to manufacturing of chemical products;
and,

SU 0.2 – Other activity related to manufacture and services.

The Use Descriptor Document states that the categories are meant to help
manufacturers and importers in mapping their markets, which is the
starting point for developing exposure scenarios.  The categories have
been limited to what the EU felt was essential for exposure scenario
building and what is needed for the tools used in exposure assessments. 
If one of the 23 defined categories is not applicable to their chemical,
manufacturers are able to select SU0.1 or 0.2 and add a NACE codes if
they need to be more specific.  In addition, manufacturers can use SU3
– Industrial Manufacturing (all) indicating the substance is broadly
used in industry.  EPA considered adopting the EU Sector of Use (SU)
codes but rejected this idea because the SU codes do not provide
sufficient specificity when differentiating between industries.

Development of New Industrial Sector Codes

EPA used information from the 2006 IUR summary statistics and EU’s use
code descriptions to develop a code that could be used to replace the
NAICS codes.  As discussed in Section 1.0, the current system of
reporting three-code combinations resulted in over 2,300 different
combinations, approximately 80 percent of which were claimed CBI.  One
of the primary considerations in developing a new replacement code is to
reduce the number of choices available to respondents. Reducing the
choices available in reporting the three-code industrial processing and
use combinations could have several benefits:

Fewer three-code combinations would aid EPA in grouping chemicals for
priority setting. 

Broader categories could lead to fewer CBI claims.  

Broader categories may reduce the number of blank or NRO responses since
respondents may know the general industrial category but not the
specific five-digit NAICS code.

For these reasons, EPA evaluated whether a reporting code could be used
in place of the NAICS code used in the 2006 IUR.  Of the IUR reporting
codes, the NAICS code has the largest number of possible choices.  EPA
first considered whether using NAICS codes with fewer digits would be
preferable to the five-digit NAICS.     REF _Ref242008199 \h  \*
MERGEFORMAT  Table 2  shows the number of possible NAICS codes for each
reporting level.

Table   SEQ Table \* ARABIC  2 . Number of Codes in Each NAICS Reporting
Level

NAICS Length	Number of Codes

2-Digit	17

3-Digit	99

4-Digit	313

5-Digit	724

6-Digit	1,175

Using the three-digit code still allows almost 100 different responses
while using the two-digit code would be insufficient for EPA’s needs. 
 In reviewing the code descriptions, the three-digit code may be
insufficient in some cases.  The 2006 IUR statistics in Table A-1 show
that over 60 percent of the NAICS codes reported were in the chemical
manufacturing series (325 series).  EPA would require a higher level of
detail than provided with a three-digit code in this series.  For
example, EPA would want to distinguish soaps and detergents (3256) from
paints and coatings (32551) since these chemicals would likely have
different use, exposure, and release scenarios. 

EPA developed the industrial sector codes (IS) to group similar NAICS
codes together while still providing the detail required for the
chemical manufacturing codes.    REF _Ref242008559 \h  \* MERGEFORMAT 
Table 3  at the end of this memorandum lists the new IS codes, a
description of the code, the rationale for selecting the codes, and the
link between the IS code and the NAICS system.  In developing the IS
codes, EPA considered the level of detail required for developing use
and exposure scenarios, the number of 2006 IUR submissions using the
code, the code definition, and the level of difficulty required in
reporting more detailed codes.  For example, only 39 of 15,151
submissions reported codes in the Agriculture series (NAICS code 11). 
The five-digit NAICS codes for this series distinguish the type of
animal or crop raised (e.g., 11111 – Soybean Farming; 11115 – Corn
Farming).  Since exposure scenarios are not likely to be dependent upon
type of crop or animal, EPA defined one IS code for all agricultural
activities.  However, submissions in the chemical manufacturing sector
(325 series) would have different exposure scenarios; therefore, EPA
developed IS codes with more detail for this sector.

The 48 IS codes in   REF _Ref242008559 \h  \* MERGEFORMAT  Table 3 
provide sufficient detail on industrial sector and can be used in
combination with the process/use code and industrial function to define
the industrial processing and use activity.  By replacing the NAICS
codes with the IS code, the number of potential three-code combinations
is reduced by about 93 percent to 7,920 combinations.  It is likely that
the number of combinations actually reported would be significantly
less.   REF _Ref242008585 \h  \* MERGEFORMAT  Table 4  shows the number
of times each IS code would have been reported in the 2006 IUR.

  REF _Ref242008590 \h  \* MERGEFORMAT  Table 5  provides a simpler view
of   REF _Ref242008559 \h  \* MERGEFORMAT  Table 3  which can be used as
a crosswalk between the NAICS code and IS code.  Respondents who know
the NAICS code can easily identify the IS code from   REF _Ref242008590
\h  \* MERGEFORMAT  Table 5 .  Respondents that do not know a specific
NAICS code may be able to identify a more general category. 

EPA developed the IS codes from the NAICS system. U.S. manufacturers are
familiar with the NAICS system since it is used in many regulatory
programs. Respondents can use the NAICS/IS crosswalk to easily translate
the NAICS codes they reported in the 2006 IUR to the new IS code.

Advantages of Industrial Sector Codes

Replacing the NAICS codes with the IS codes has several advantages
during IUR data collection, processing, and analysis:

Data Collection

Reduces the number of unique industrial sectors for respondents to
select.  Respondents will still be able to translate known NAICS codes
to IS codes.  Respondents that do not know the specific NAICS code may
be able to provide the more descriptive IS code, thus reducing the
number of NROs or blanks reported.

Reduces the number of three-code combinations that respondents need to
report.  Currently, respondents only report the ten three-code
combinations that account for the highest percentages of the production
volume.  Reducing the number of combinations may provide EPA with more
information for some chemicals.

Broader groups may reduce burden on respondents since they do not need
to determine a specific five-digit NAICS code.

Data Processing and Analysis

Chemicals are automatically classified into fewer groups which will
reduce the number of unique chemical exposure scenarios and help EPA
prioritize and screen chemicals.

May reduce the number of invalid entries since there will likely be
fewer transcription errors (e.g., 32591 instead of 32519).

The IS codes can be easily programmed into the e-IUR software.

The broader IS codes may result in fewer CBI claims which will allow EPA
to make more information available to the public.

The IS codes more closely align to the EU Sector of Use codes which will
allow EPA to compare U.S. data with that collected by the EU.
