Proposed rule.


EPA is proposing to remove the molecular weight limitations from the tolerance exemption expression for certain polymeric substances codified in 40 CFR 180.960. These exemptions from the requirement of a tolerance were established based on the polymer's meeting the criteria established by the Agency in 40 CFR 723.250, which define a low risk polymer. The Agency is acting on its own initiative.

II. Background

A. What is the Agency's Authority for Taking this Action?

The rule proposed here would be issued pursuant to section 408(e) of the Federal Food, Drug, and Comestic Act (FFDCA), as amended by FQPA (21 U.S.C. 346a(e)). Section 408 of FFDCA authorizes the establishment of tolerances, exemptions from the requirement of a tolerance, modifications in tolerances, and revocation of tolerances for residues of pesticide chemicals in or on raw agricultural commodities and processed foods. Without a tolerance or tolerance exemption, food containing pesticide residues is considered to be unsafe and therefore “adulterated” under section 402(a) of FFDCA. If food containing pesticide residues is found to be Start Printed Page 72759adulterated, the food may not be distributed in interstate commerce (21 U.S.C. 331(a) and 342 (a)).

B. What Action is the Agency Taking?

In the Federal Register of May 24, 2002, (67 FR 36525) (FRL-6834-2), EPA issued a direct final rule to add a new section to part 180, subpart D. This section now lists the pesticide chemicals that are polymers subject to exemptions from tolerance requirements, based upon the criteria in 40 CFR 723.250 that identify a low-risk polymer. Under the Toxic Substances Control Act (TSCA), polymers meeting the criteria of 40 CFR 723.250 are exempt from certain of the premanufacture notice requirements. The Office of Pesticide Programs has used these same criteria to create a stream-lined process for establishing a tolerance exemption for a polymeric substance meeting these criteria. In essence, a manufacturer by filing a petition for an exemption from the requirement of a tolerance (which includes the notice of filing) with the Agency's Office of Pesticide Programs is verifying their exemption under section 5(a)(1)(A) of TSCA. In a similar manner, a manufacturer who petitions the Agency for tolerance exemption status by stating that their polymer is described by the chemical nomenclature of a polymer exempted under 40 CFR 180.960 is verifying their exemption under 5(a)(1)(A) of TSCA.

Many of the polymers that were transferred from other sections of the CFR to this new section contained limitations on the molecular weight, usually expressed in a manner similar to the following, “minimum number average molecular weight (in amu),” as part of their nomenclature. At the time that these exemptions were established (pre-May 2002) including such a limitation assured that polymeric substances that were described by the chemical nomenclature but were of lower molecular weight were not considered to be exempt from the requirement of a tolerance. At the time of the transfer to 40 CFR 180.960, this nomenclature was maintained.

The molecular weight criteria that define a low risk polymer are specified in 40 CFR 723.250(e), and are not limited to the particular molecular weights currently specified in 40 CFR 180.960. In promulgating 40 CFR 180.960, EPA incorporated the criteria of 40 CFR 723.250(e) as a requirement for all polymer exemptions. Because 40 CFR 180.960 through its incorporation of 40 CFR 723.250(e) now imposes a minimum molecular weight to assure safety, chemical-specific limitations are not needed in 40 CFR 180.960, and EPA proposes to modify the tolerance exemptions accordingly.

III. Statutory and Executive Order Reviews

This proposed rule removes the chemical-specific molecular weight limitations codified in the tolerance exemption expressions in 40 CFR 180.960. Since removal of these chemical-specific molecular weight limitations does not impose any new requirements, it is not subject to review by the Office of Management and Budget (OMB) under Executive Order 12866, entitled Regulatory Planning and Review (58 FR 51735, October 4, 1993). Because this proposed rule is not subject to review under Executive Order 12866, this proposed rule is not subject to Executive Order 13211, Actions Concerning Regulations That Significantly Affect Energy Supply, Distribution, or Use (66 FR 28355, May 22, 2001). This proposed rule does not contain any information collections subject to OMB approval under the Paperwork Reduction Act (PRA), 44 U.S.C. 3501 et seq., or impose any enforceable duty or contain any unfunded mandate as described under Title II of the Unfunded Mandates Reform Act of 1995 (UMRA) (Public Law 104-4). Nor does it require any special considerations under Executive Order 12898, entitled Federal Actions to Address Environmental Justice in Minority Populations and Low-Income Populations (59 FR 7629, February 16, 1994); or OMB review or any Agency action under Executive Order 13045, entitled Protection of Children from Environmental Health Risks and Safety Risks (62 FR 19885, April 23, 1997). This action does not involve any technical standards that would require Agency consideration of voluntary consensus standards pursuant to section 12(d) of the National Technology Transfer and Advancement Act of 1995 (NTTAA), Public Law 104-113, section 12(d) (15 U.S.C. 272 note). Under the requirements of the Regulatory Flexibility Act (RFA) (5 U.S.C. 601 et seq.), the Agency hereby certifies that this proposed action will not have significant negative economic impact on a substantial number of small entities. In addition, the Agency has determined that this action will not have a substantial direct effect on States, on the relationship between the national government and the States, or on the distribution of power and responsibilities among the various levels of government, as specified in Executive Order 13132, entitled Federalism (64 FR 43255, August 10, 1999). Executive Order 13132 requires EPA to develop an accountable process to ensure “meaningful and timely input by State and local officials in the development of regulatory policies that have federalism implications.” “Policies that have federalism implications” is defined in the Executive Order to include regulations that have “substantial direct effects on the States, on the relationship between the national government and the States, or on the distribution of power and responsibilities among the various levels of government.” This proposed rule directly regulates growers, food processors, food handlers and food retailers, not States. This action does not alter the relationships or distribution of power and responsibilities established by Congress in the preemption provisions of section 408(n)(4) of the FFDCA. For these same reasons, the Agency has determined that this proposed rule does not have any “tribal implications” as described in Executive Order 13175, entitled Consultation and Coordination with Indian Tribal Governments (65 FR 67249, November 6, 2000). Executive Order 13175, requires EPA to develop an accountable process to ensure “meaningful and timely input by tribal officials in the development of regulatory policies that have tribal implications.” “Policies that have tribal implications” is defined in the Executive Order to include regulations that have “substantial direct effects on one or more Indian tribes, on the relationship between the Federal Government and the Indian tribes, or on the distribution of power and responsibilities between the Federal Government and Indian tribes.” This proposed rule will not have substantial direct effects on tribal governments, on the relationship between the Federal Government and Indian tribes, or on the distribution of power and responsibilities between the Federal Government and Indian tribes, as specified in Executive Order 13175. Thus, Executive Order 13175 does not apply to this proposed rule.
