E7-21594. Pesticide Inert Ingredients: Support Status of Revoked Tolerance Exemptions

AGENCY:

Environmental Protection Agency (EPA).

ACTION:

Notice.

SUMMARY:

EPA has received notice from various companies of their intention to submit data in order to support the reinstatement of a number of inert ingredient tolerance exemptions that were revoked because of insufficient data, revocations effective as of August 9, 2008, in a final rule published in the Federal Register on August 9, 2006 (71 FR 45415). This notice identifies the tolerance exemptions that the companies indicate they will be supporting with the submission of data. The information in this notice is for informational purposes only and does not affect the previous revocations. Based on the review of the submitted data, EPA will conduct rulemaking to establish new tolerance exemptions where appropriate.

II. Background

A. Background on the Revocation of Pesticide Inert Ingredient Tolerance Exemptions on August 9, 2006

In a final rule published in the Federal Register on August 9, 2006 (71 FR 45415) (FRL-8084-1), EPA revoked inert ingredient tolerance exemptions because insufficient data were available to the Agency to make the safety determination required by FFDCA section 408(c)(2). In making the FFDCA reassessment safety determination, EPA considered the validity, completeness, and reliability of the data that are available to the Agency [FFDCA section 408 (b)(2)(D)] and the available information concerning the special susceptibility of infants and children (including developmental effects from in utero exposure) [FFDCA section 408 (b)(2)(C)]. Data gaps existed for these inert ingredients in areas that were critical to reassessment. Without these data, the assessment of possible effects to infants and children could not be made. EPA concluded it had insufficient data to make the safety finding of FFDCA section 408(c)(2) and revoked the inert ingredient tolerance exemptions identified in the final rule under 40 CFR 180.910, 180.920, 180.930, and 180.940, with the revocations effective two years after the date of publication. The tolerance exemptions will expire on August 9, 2008.

B. What Information Is Provided In This Notice?

EPA has received communications from pesticide registrants and inert ingredient manufacturers expressing interest in supporting certain inert ingredient tolerance exemptions that were revoked in the final rule of August 9, 2008. EPA developed voluntary guidance describing how interested parties could support these revoked tolerance exemptions, including consultations with the Agency and how they can demonstrate support, including identifying test materials and providing evidence that a laboratory has been hired to conduct the study. The voluntary guidance document, entitled “Guidance for Supporting the Inert Ingredients Subject to the Revocation Notice of August 9, 2006”, is available on EPA's website at http://www.epa.gov/​opprd001/​inerts/​.

In the interest of keeping the stakeholders informed about activities that may impact these revoked tolerance exemptions, EPA is publishing in this notice the support status of each of the revoked tolerance exemptions by indicating whether the Agency has received a demonstration of support (such as described in the guidance document discussed above).

Be advised that the information provided in this notice does not guarantee or in any way bind the Agency to reinstate tolerance exemptions, establish new tolerance exemptions, or grant extensions to expiring tolerance exemptions. EPA cannot guarantee that the parties will, in fact, submit any data at all. Additionally, it is possible that the data submitted to support a tolerance exemption may not support a safety finding under FFDCA section 408(c)(2). In these cases, the tolerance exemption will not be reinstated nor will a new one be established. The information being published here is designed simply to inform interested stakeholders about the tolerance exemptions for which the Agency has received a demonstration of support. EPA recommends that you contact the chemical suppliers to confirm their plans for supporting a tolerance exemption.

It is important to note that several parties have indicated that they may want to support only a portion of a tolerance exemption expression that includes a range of chemicals. At this time, EPA does not know exactly what range of chemicals within a tolerance exemption will eventually be supported by data. Until the data are submitted and reviewed, EPA will not know what portion, if any, of a current tolerance exemption can be reinstated. If the results of the data permit, a supported exemption may be reinstated in whole, or a new tolerance exemption may be established if only a part of a revoked exemption is supported by the data. Again, contact the chemical suppliers to confirm their plans for supporting a tolerance exemption. Unit III. of this document provides the tolerance exemptions the parties assert they are supporting.

III. Support Status of Revoked Tolerance Exemptions

The following provides the support status of each of the inert ingredient tolerance exemptions revoked because of insufficient data. The tolerance exemptions are presented below in the order they appeared in the final rule published in the Federal Register on August 9, 2006 (71 FR 45415). The support status has been added to the end of each tolerance exemption expression. For example, under § 180.910, the entry for the tolerance exemption expression “y. Sodium mono-, di-, and tributyl naphthalenesulfonates” ends with “(Demonstration of Support)”, which means that the EPA has received communication from a party that they intend to submit data supporting reinstatment of all or part of the tolerance exemption and the parties have taken measures to demonstrate their support to the Agency such as those described in the voluntary guidance document (discussed above). On the other hand, under § 180.910, the entry for the tolerance exemption expression “v. Sodium lauryl glyceryl ether sulfonate” ends with “(No Demonstration of Support)”, which means the EPA has not received communication from a party concerning support of the exemption and/or has not received a sufficient demonstration of support. Tolerance exemptions that are not supported by the submission of adequate data will expire on August 9, 2008. If EPA determines that specific tolerance exemptions scheduled to expire are supported by adequate data, the Agency intends to conduct rulemaking to reinstate the exemptions or create new tolerance exemptions for the affected commodities. EPA recommends that you contact the chemical suppliers to confirm their plans for supporting a tolerance exemption.

Also, the final rule published in the Federal Register on August 9, 2006 (71 FR 45415) revoked two inert ingredient tolerance exemptions that were inadvertently removed from the CFR some time ago but are considered to be an active tolerance exemptions under §§ 180.910 and 180.930. The support status of these tolerance exemptions is found at the end of §§ 180.910 and 180.930.

In addition to the revocation of tolerance exemptions for insufficient data, an administrative revocation was completed for seven redundant and incorrect tolerance exemptions under 40 CFR part 180 in the final rule published in the Federal Register on August 9, 2006 (71 FR 45415). These tolerance exemptions were revoked on the date of publication of the final rule. These seven tolerance exemptions appear in the list below so as to maintain the original order of the list of tolerance exemptions as given in the final rule and facilitate the reader's ability to determine the support status of each of the tolerance exemptions revoked for insufficient data. The status of the seven exemptions is indicated as “(Administrative Revocation is Complete)”.

In the final rule published in the Federal Register on August 9, 2006 (71 FR 45415), the Agency revoked one other inert ingredient tolerance exemption that was inadvertently removed from the CFR some time ago but is considered to be an active tolerance exemption under § 180.930:

“α-Alkyl (C₁₂-C₁₅)-ω-hydroxypoly(oxyethylene) sulfate and its ammonium, calcium, magnesium, potassium, sodium, and zinc salts; the poly(oxyethylene) content averages 3 moles.” (Demonstration of Support)

Under § 180.940:

Under paragraph (a):

i. α-Alkyl(C₁₀-C₁₄)-ω- hydroxypoly (oxyethylene) poly(oxypropylene) average molecular weight (in amu), 768 to 837. (No Demonstration of Support)

ii. α-Alkyl(C₁₂-C₁₈)-ω hydroxypoly (oxyethylene) poly(oxypropylene) average molecular weight (in amu), 950 to 1120. (No Demonstration of Support)

Under paragraph (b):

i. α-Lauroyl-ω-hydroxypoly (oxyethylene) with an average of 8-9 moles ethylene oxide, average molecular weight (in amu), 400. (No Demonstration of Support)
