Septemb er 26, 2013,

lI. Extension Reqgrest

In its Septemb er 26,2073 determination letter, trPA stated that a new study plan for the ,lg"*

test must be submitted to the Agency with the final report submitted by October 1,2,201'4.

The Agency subsequently granted the PCBTF Testing Consortium's request dated }rlovembet

6,201,3 for a delay to the date by which the final report must be submitted. This date was

December 72,201,4 which was granted by EPA in its response

The PCBTF Testing Consortium is requesting an additional extension due to the fact that

there has been a significant delay in the development of the final study plan because the

substance's high volatility and low watet solubility have presented a number of technical

challenges which needed to be resolved among the laboratorf, the Consorlium, and EPA.

Indeed, the original snrdy plan that was submitted to EPA inJanuary of this ye r resulted in a

significant number of comments from the Agency. These commeflts were received in March.

The Consortium then required additional time to review and tespond to EPA's corruneflts, as

well as work with a laboratory to address these complex technical issues. Because of

subsequent comments and questions raised by the laboratory, the Consortium was compelled

to submit additional, follou/ up questions back to the Agency in August in order to obtain

EPA's guidance on the conduct of the test. Due to a backlog, the Agency was delayed in

responding to this request until October. It then took an additional month to work with the

laboratory ro develop the final study plan. The study plan has now been finalized and signed

between the Consottiurn and the laboratory.3

The laborarory expects that the experimental starting date will be in the second half of

November with a draft report issued sometime in mid to late January. It is also quite possible

that because of the substaflce's high volatiJity and poor water solubility, technical issues fflcy

atise in the course of the test which may require input ftom EPA in order to addtess and

resolve. It is likely also that the holidays may cause delay. Therefore, the PCBTF Testing

The Consortium understands that EPA will accept a schedule modifi.cation tequest if such a

request is made in accordance with 40 CFR 790.55. Concuttent with this, the Agency stated

the following tr the final rule:

A company that submits a letter of intent to test under the final rule and that

subsequently anticipates difficulties in completing the testing by the deadline set

forth in the final rule may submit a modification request to the Agency, pursuant to

40 CFR 790.55. EPA will determine whether modification of the test schedule is

appropriate...a

nflith respect to the requirements set foth 

^t 

40 CFR 790.55, The Consortium does not believe

that the requested modification to the test schedule requested herein would "significandy altet

the scope of the test[s] or significantly change the schedule for completing the test[s]" because

it does notmeetany of the conditions set forth at79A.55FX4)(4-(rv) and furthet because it

does not dse to the level of "signiftcant" in terms of time.s Moreover, this alleviates EPA from

having to seek public coffrment befote apptoving these modifications.

The Consoftium believes that this additional extension to the test schedule is a minot schedule

modification and would not prevent the Agency from meeting its statutory obligations under

TSCA Section 4 or its voluntary commitments under eithet the HPV Chemical Challenge

Progtam or the OECD HPV SIDS Program. In addidon, this schedule modification tequest

does not significantly change the schedule for completing the tests as described in 790.55.

The Consottium thanks the Agency fot its

coftunents, and detetminations concerning
