blank when data is not known or reasonably ascertainable

In some instances EPA is requesting that you explain why data is not
available

EPA encourages participants to provide as much data as possible
including why data is not available

You may use the form as a guide to determine which data to report to EPA

Participation in and submission of data to the Program does not imply an

ATTN: NANOSCALE MATERIALS STEWARDSHIP PROGRAM

	This form has been developed for the U.S. EPA’s Nanoscale Materials
Stewardship Program.  To ease the burden of reporting, the form is based
on the standard Premanufacture Notice (PMN) form (EPA FORM 7710-25, Rev.
5-95); many of the pages in this form are adapted from those in the PMN
form; irrelevant sections have been removed.  Additional pages seeking
nanoscale materials-specific information are inserted in the most
relevant places.

GENERAL INSTRUCTIONS

As much of this form is adapted from the PMN form, it may be instructive
to read “Instruction Manual for Reporting Under the TSCA §5 New
Chemicals Program” (available from the Toxic Substances Control Act
(TSCA) Information Service, 202-554-1404, or 202-554-5603(fax) or at
http://www.epa.gov/opptintr/newchems/pubs/pmnforms.htm).

Just as in a standard PMN, provide all information requested in this
form to the extent it is known or reasonably ascertainable. 
Particularly as related to the health and environmental effects of the
manufacture, processing, distribution in commerce, use, or disposal of
the substance, all test data in your possession or control and a
description of all other known data should be provided.  Reasonable
estimates or modeling data may be given in the absence of actual data. 
Standard literature citations may be submitted for data in the open
scientific literature.  Complete test data report (written in English),
not summary data, should be submitted, if they do not appear in the open
literature.  Clearly identify whether test data is on the substance, on
an analog, or from models.  

Any answer may be left blank or filled with “N/A,” if the
information is not available, or the question is not applicable (e.g.,
characterization data for tests that were not run, production volume for
materials that are not at the production stage, CAS name and number for
materials not registered with CAS, etc.).  IT IS NOT NECESSARY TO DO
ADDITIONAL TESTING IN ORDER TO COMPLETE THIS FORM.  

Attach additional sheets as needed.  Label each continuation sheet with
the corresponding section heading.  List all attachments including data
and optional information on page 15.  

Only one substance should be submitted per form.

Any information may be claimed as confidential.  To assert a claim on
the form, mark (X) the confidential box next to the information claimed
as confidential.  To assert a claim in an attachment, circle or bracket
the information claimed as confidential.  If information is claimed as
confidential, a sanitized version (including attachments) should be
provided.  For additional instructions on claiming information as
confidential, read the Instructions Manual.  Submission of confidential
information on this form constitutes consent for disclosure of the
information to EPA contractors under the security procedures used in
handling information submitted under TSCA. 

NOTICES 

Participation in and submission of data to the Program is voluntary.  

Use of this form by Program participants is also voluntary. 

Participation in and submission of data to the Program does not imply an
intent to manufacture or import for a commercial purpose.

Completion and submission of this form to the Program does not satisfy
any requirement under 40 CFR part 720 to submit a PMN or under 40 CFR
part 721 to submit a Significant New Use Notice. For information on PMN
submissions, see   HYPERLINK
"http://www.epa.gov/opptintr/newchems/index.htm" 
http://www.epa.gov/opptintr/newchems/index.htm 

TEST DATA  Hazard and exposure test data would be most useful if the
physical/chemical properties of the nanoscale material relevant to
assessing test results are obtained at the initiation of testing. 
Additional relevant information on preparation of the nanoscale material
for administration and storage history of the material between
production and administration will assist in interpretation. When
possible, interpret data in the context of accompanying positive and
negative nanoscale substance control data from the same test system.
Indicate which of the following data are included in this submission:

  FORMCHECKBOX   Physical / Chemical properties

  FORMCHECKBOX   Structure / activity relationships	  FORMCHECKBOX  
Health effects

  FORMCHECKBOX   Exposure ERiskEassessments	  FORMCHECKBOX

OPTIONAL POLLUTION PREVENTION INFORMATION

To claim information in this section as confidential circle or bracket
the specific information that you claim as confidential.

In this section you may provide information not reported elsewhere in
this form regarding your efforts to reduce or minimize potential risks
associated with activities surrounding manufacturing, processing, use
and disposal of the substance.  Please include new information pertinent
to pollution prevention, including source reduction, recycling
activities and safer processes or products available due to the chemical
substance.  Source reduction includes the reduction in the amount or
toxicity of chemical wastes by technological modification, process and
procedure modification, product reformulation, raw materials
substitution, and/or inventory control.  Recycling refers to the
reclamation of useful chemical components from wastes that would
otherwise be treated or released as air emissions or water discharges,
or land disposal.  Descriptions of pollution prevention, source
reduction and recycling should emphasize potential risk reduction
subsequent to compliance with existing regulatory requirements and can
be either quantitative or qualitative.  EPA is interested in the
information to assess overall net reductions in toxicity or
environmental releases and exposures, not the shifting of risks to other
environmental media or non-environmental areas (e.g., occupational or
consumer exposure).  In addition, information on the relative cost or
performance characteristics of the substance to potential alternatives
may be provided.

** Notes

Part I

Section B:  It is recognized that systematic nomenclature has not been
fully developed for nanoscale materials, therefore it is not necessary
to provide the “correct Chemical Abstract name” nor the “CAS
Registry Number,” if it does not exist.  Please fill out these
sections to the best of your ability in light of the limitations.  

B.1.a:  It is noted that a nanoscale material may or may not be
accurately described as a Class 1 or Class 2 substance.  If the choice
is not obvious, this section may be left blank.  In addition, a brief
explanation may be given for why a particularly classification is or is
not appropriate.

B.1.b / B.2.d:  If a Chemical Abstracts Name is not available, please
use a name that is most in agreement with CA nomenclature.

B.1.d may be read as: 

d. Molecular formula (including molecular shape / physical form) and CAS
Registry Number (if a number already exists for the substance).

B.1.e:  For the nanoscale material, please provide the information
requested for Class 2 substances, regardless of whether the material is
Class 1 or Class 2 or cannot be determined. 

B.2.e may be read as:

"Provide a correct representative or partial chemical structure diagram,
as complete as can be known, if one can be reasonably ascertained. 
Alternatively, if applicable, provide a correct representative structure
for the polymer as part of a composite."

[Note: the components of a composite are separate chemical identities. 
For example in a composite of starch molecules between layers of clay
treated with surfactants, the starch, clay, and surfactants might be on
the TSCA Inventory, but since the interactions between the components
are weak electrical interactions, there is no chemical substance.]

Physical and Chemical Properties Worksheet

It is noted that, for nanoscale materials, protocols and methods may not
exist or be standardized for measurement of the physical and chemical
properties listed in this worksheet.
