EPA Revokes TSCA Testing for Four Chemicals, Modifies for Six
The Environmental Protection Agency has issued a direct final rule to revoke certain testing requirements for six chemical substances and all the testing requirements for four chemical substances due to information received since publication of the first test rule for certain high production volume chemical substances (HPV1). HPV1 had established testing requirements for these 10 chemical substances.

(Section 4(a) of Toxic Substances Control Act authorizes EPA to require testing if certain findings are made. EPA is amending the chemical testing requirements for the 10 HPV chemical substances in 40 CFR 799.5085 because some of the findings that EPA made for these 10 chemical substances are no longer supported. These findings were that: (1) the chemical substances were produced in substantial quantities, (2) there are insufficient data upon which the effects of manufacture, distribution, processing, use, or disposal of those chemical substances on health or the environment can reasonably be determined or predicted, and (3) testing of the chemical substance with respect to such effects is necessary to develop such data.)
Revocations Effective May 15 Unless Adverse Comments or Request for Hearing
Persons who export or intend to export the four chemical substances for which all the testing requirements are revoked will no longer be subject to section 12(b) of the Toxic Substance Control Act (TSCA) export notification requirements triggered by HPV1, effective May 15, 2012, unless EPA receives adverse comment in writing, or a request to present comment orally, on or before April 16, 2012.
(If EPA receives adverse comment, or a written request for an opportunity to present oral comments, EPA will publish a timely withdrawal in the Federal Register informing the public that this direct final rule, or relevant portions of this direct final rule, will not take effect.)
Ten Affected HPV1 Chemical Substances
This direct final rule revokes the testing requirements for the following four chemical substances:
- Acetyl chloride (CAS No. 75--36--5);
- imidodicarbonic diamide (CAS No. 108--19--0);
- methane, isocyanato- (CAS No. 624--83--9);
- and urea, reaction products with formaldehyde (CAS No. 68611--64--3).
This direct final rule also revokes some of the testing requirements for the following six chemical substances:
- 9,10--Anthracenedione (CAS No. 84--65--1);
- 1-chlorododecane (CAS No. 112--52--7);
- phenol, 4,4′-methylenebis [2,6-bis(1,1-dimethylethyl)]- (CAS No. 118--82--1);
- methanesulfinic acid, hydroxyl-,monosodium salt (CAS No. 149--44--0);
- benzenesulfonic acid, [[4-[[4-(phenylamino)phenyl][4-(phenylimino)-2,5-cyclohexadien-1-ylidene]methyl]phenyl]amino]- (CASNo. 1324--76--1); and
- C.I. Solvent Black 7 (CAS No. 8005--02--5).
EPA states that it is basing its decision to revoke all testing requirements for four chemical substances and some of the testing requirements for six other chemical substances on information received since publication of HPV1 (40 CFR 799.5085), as described in this unit.
