If there are any questions that cannot be answered via email or if this is the first time the
submitter is preparing an inert ingredient petition, the Agency recommends that a submitter
request a pre-submission meeting with the Inert Ingredients Team prior to submitting your
request. This is an informal discussion to determine if the petitioner has enough information to
proceed with the petition process. The petitioner will need to provide a brief summary of the
information they have regarding the inert ingredient, including use information, limitations,
sections of the CFR that apply, and toxicity and environmental fate data. CITAB will determine
if additional information is needed in order to make a safety finding regarding the inert

Sources of Data

Sources of information that may be submitted to the Agency include, but are not limited to, OCSPP
guideline studies4; publicly available literature and data, including peer-reviewed assessments and
journals (e.g. WHO, OECD SIDS, IUCLID, EPAHPV, IRSI, etc.); modeled data5; and
analog/surrogate data.

If sufficient data does not exist on the submitted chemical and analog/surrogate data (e.g.

Structural Activity Relationship (SAR) data) is being submitted, please include a scientific
discussion as to why the surrogate data is relevant/adequate for read across/bridging to the
subject chemical. If sufficient explanation and rationale is not provided, then the petition will be
rejected, and the data will not be considered for review.

Unacceptable sources of data include:

1.	MSDS sheets: A MSDS is only useful if the product contains 100% of the chemical in
question and it clearly states this on the MSDS. In addition, in order for the toxicity data
to be used by the Agency in the risk assessment process it must come from an acceptable
accessible source and the source must be cited on the MSDS and a copy of the study must
also be provided.

2.	Unpublished studies that are submitted without the full study report.

Data Formatting

1.	PR Notice 2011-3: there are standard data format requirements for all study data
submitted to the Agency under the Federal Insecticide, Fungicide, and Rodenticide Act
(FIFRA) and Certain Provisions of the Federal Food, Drug, and Cosmetic Act (FFDCA).
These requirements are outlined in (PR) Notice 2011-3. Submitted data packages that do
not conform to these requirements may be rejected by the Agency's Document
Processing Desk and returned to you for revision.

2.	Petition Layout: Chapter 11 of EPA Pesticide Registration Manual provides additional
information about the format of the petition. We encourage you to use these formatting
guidelines for your inert ingredient submission.

3.	Study profile templates: These templates describe the layout and scope of information
that should be contained within a study profile and can serve as a guide for the
preparation of study documents. While these templates are not required, they can be used
by the Agency to efficiently develop its own review of the study. The templates can be
found at https://www.epa.gov/pesticide-registration/study-profile-templates

4. Submission of Data:

a.	Independent/Company studies that have not been peer reviewed or previously
reviewed by the Agency will need to be submitted in their entirety.

b.	MRID #s of previously submitted studies cited in support of your petition.

c.	A complete bibliography of all studies/documents cited and other supporting
material.

d.	If the chemical has already been reviewed (e.g. the chemical is also registered as
an active ingredient or it has another existing tolerance exemption for use as an
inert ingredient) then the company should provide a copy of the EPA assessment
that summarized the data.

Inert Ingredient Review Process

The Agency screens all PRIA submissions during a 21 Day Screen for adequacy/completeness
upon receipt. Submission packages not deemed acceptable are returned to the applicant to correct
the deficiency. The PRIA 5 decision review times are listed in the PRIA Fee Category table
https://www.epa.gov/pria-fees/pria-fee-category-table-inert-ingredients. Once a more in-depth
review of the chemical is underway, deficiencies may arise, and additional information may be
requested.

In addition to the 21 Day Screen under PRIA 5, the Agency also conducts a preliminary technical
screen of the application to determine if the application and the data/information submitted with
the application are accurate and complete; whether the application, data and information are
consistent with any proposed tolerance or tolerance exemption; and if the application, data and
information are such that, subject to a full review, could result in the granting of the application.

This screening is conducted no later than 45 days after the start of the decision review period for
actions with decision review time periods equal to or less than six months and no later than 90
days after the start of the decision review time for actions with decision review time periods
greater than six months. If the application fails the technical screen, and the deficiencies cannot
be corrected by the applicant within 10 business days after receipt of the Agency's notification
of the failure, the Agency will reject the application.

After the review and risk assessment are completed, a decision will be made regarding the safety
of the inert ingredient in question. A Final Rule outlining the decision will be published in the
Federal Register. After the rule granting the use of the chemical is published, the inert ingredient
will be permitted for use under the appropriate use pattern.
