inspection and copying requirements shall not apply to quality assurance 
unit records of findings and problems, or to actions recommended and 
taken, except the EPA may seek production of these records in litigation 
or formal adjudicatory hearings.
    (b) EPA will not consider reliable for purposes of showing that a 
chemical substance or mixture does not present a risk of injury to 
health or the environment any data developed by a testing facility or 
sponsor that refuses to permit inspection in accordance with this part. 
The determination that a study will not be considered reliable does not, 
however, relieve the sponsor of a required test of any obligation under 
any applicable statute or regulation to submit the results of the study 
to EPA.
    (c) Since a testing facility is a place where chemicals are stored 
or held, it is subject to inspection under section 11 of TSCA.



Sec. 792.17  Effects of non-compliance.

    (a) The sponsor or any other person who is conducting or has 
conducted a test to fulfill the requirements of a testing consent 
agreement or a test rule issued under section 4 of TSCA will be in 
violation of section 15 of TSCA if:
    (1) The test is not being or was not conducted in accordance with 
any requirement of this part;
    (2) Data or information submitted to EPA under this part (including 
the statement required by Sec. 792.12) include information or data that 
are false or misleading, contain significant omissions, or otherwise do 
not fulfill the requirements of this part; or
    (3) Entry in accordance with Sec. 792.15 for the purpose of auditing 
test data or inspecting test facilities is denied. Persons who violate 
the provisions of this part may be subject to civil or criminal 
penalties under section 16 of TSCA, legal action in United States 
district court under section 17 of TSCA, or criminal prosecution under 
18 U.S.C. 2 or 1001.
    (b) EPA, at its discretion, may not consider reliable for purposes 
of showing that a chemical substance or mixture does not present a risk 
of injury to health or the environment any study which was not conducted 
in accordance with this part. EPA, at its discretion, may rely upon such 
studies for purposes of showing adverse effects. The determination that 
a study will not be considered reliable does not, however, relieve the 
sponsor of a required test of the obligation under any applicable 
statute or regulation to submit the results of the study to EPA.
    (c) If data submitted to fulfill a requirement of a testing consent 
agreement or a test rule issued under section 4 of TSCA are not 
developed in accordance with this part, EPA may determine that the 
sponsor has not fulfilled its obligations under section 4 of TSCA and 
may require the sponsor to develop data in accordance with the 
requirements of this part in order to satisfy such obligations.

growth chambers, and other holding, rearing, and breeding areas, and 
accessory equipment, shall be cleaned and sanitized at appropriate 
intervals.
    (g) Feed, soil, and water used for the test systems shall be 
analyzed periodically to ensure that contaminants known to be capable of 
interfering with the study and reasonably expected to be present in such 
feed, soil, or water are not present at levels above those specified in 
the protocol. Documentation of such analyses shall be maintained as raw 
data.
    (h) Bedding used in animal cages or pens shall not interfere with 
the purpose or conduct of the study and shall be changed as often as 
necessary to keep the animals dry and clean.
    (i) If any pest control materials are used, the use shall be 
documented. Cleaning and pest control materials that interfere with the 
study shall not be used.
    (j) All plant and animal test systems shall be acclimatized to the 
environmental conditions of the test, prior to their use in a study.
