TRI Source Reduction Reporting
Questions and Answers

What is source reduction?

EPA's Toxics Release Inventory (TRI) Program refers to source
reduction as any practice that reduces, eliminates, or prevents
pollution from being released or entering a waste stream. Source
reduction differs from other waste management practices, such as
recycling and treatment, which refer to how chemical waste is
managed after it is generated.

Can source reduction be reported to TRI every year?

A new source reduction activity must be reported in the year that it is
started or fully implemented. Updates on ongoing efforts may be
described in the optional section of the TRI reporting form.

How should multi-year activities be reported?

Source reduction activities that form part of large multi-phase, multi-
year projects should be tracked separately. Facilities should report
each distinct activity in the year it is implemented. For example, if a
facility identifies several changes that will be implemented between
2018 and 2020, and implements one change each year, the facility
should report one activity for Reporting Year (RY) 2018, one for RY
2019, and one for RY2020.

How significant of an activity should be reported?

Each TRI reporting form should include all source reduction activities
implemented for the chemical being reported; no source reduction
activity is insignificant or too small to be reported. Continuous
improvement is common at facilities, and when source reduction
improvements are implemented, they must be reported. EPA also
encourages facilities to provide additional details regarding (1) how
source reduction was achieved, and (2) any barriers that prevented
source reduction. These details will help EPA and others learn from
facilities' successes and challenges.

What effect will implementing a source reduction
activity have at my facility?

Assuming all other factors are fixed, facilities should expect releases and other
waste managed quantities to decrease due to source reduction. However,
consider:

Not all source reduction activities result in the same environmental
impact. For example, implementing good operating practices may result in
less of a decrease than raw material modifications.

Source reduction activities may only be feasible for certain chemicals or
processes, and the resulting aggregate quantities may not truly reflect the
quantities reduced or eliminated.

Increased production may also impact the quantity of waste generated.

Reporting Source
Reduction to TRI

Required Reporting

Facilities MUST report their new source

reduction activities (TRI form, Sec. 8.10).

•	Activities are reported by selecting
the source reduction activity code
that best describes the actions taken.
There are 49 activity codes that fall
into 8 categories.

•	Facilities must also indicate how the
activity was identified by selecting at
least one method code.

Optional Reporting

Facilities MAY report other source

reduction information (TRI form, Sec.

8.11), including:

•	An estimate of the expected reduction
in the annual amount of chemical
waste managed;

•	Additional details (in narrative form)
on any source reduction practices or
other environmental management
practices that provide greater insight
into the activities implemented;
and/or

•	Barriers that prevent the
implementation of source reduction
activities at the facility.

How much information do I have to share?

Facilities must indicate, through the selection of codes, the source
reduction activity that best aligns with the practice implemented during
the year.

You are encouraged, however, to provide enough details (through
optional narratives) to showcase your facility's accomplishments in
source reduction, and for others to better understand the source
reduction activity implemented. If possible, describe how chemicals were
eliminated or provide details on substitutions (such as giving names of
alternative chemicals used).

What are the benefits of sharing source reduction
information with EPA?

Benefits of reporting on source reduction practices, especially with
detailed narratives, include:

•	Contributing to a shared knowledge base of source reduction
practices implemented by industry;

•	Promoting awareness of environmental stewardship among local
communities;

•	Learning from information provided by industry peers along the value
chain, which may lead to the identification of more P2 opportunities;

•	Tracking and gauging your facility's performance;

•	Having pollution prevention activities possibly showcased through
case studies or other forms of recognition; and

•	Enabling identification of technological areas where research is
needed on less-polluting alternatives.

You can find examples of source reduction reporting using EPA's Pollution Prevention Search Tool. An example of free-
text entries from a facility report is shown below. To learn more about TRI and Pollution Prevention, visit

Pollution Prevention at
Nordic Ware

Nordic Ware is a kitchenware
manufacturer based in Minneapolis.
This facility worked with its suppliers
to reduce the amount of glycol ethers
in its coatings and found new
cleaning solutions with lower
quantities of glycol ethers. By 2013,
Nordic Ware decreased the quantity
of glycol ethers used on-site to below
the TRI reporting threshold.*
