SUPPLEMENTARY INFORMATION: I. Electronic Availability Internet: Electronic copies of this document and various support documents are available from the EPA Home Page at the Federal Register--Environmental Documents entry for this document under ``Laws and Regulations'' (http://www.epa.gov/fedrgstr/EPA-TOX/1998/). II. Background EPA proposed health effects testing under section 4(a) of the Toxic Substances Control Act (TSCA) on June 26, 1996, for a number of HAPs chemicals (61 FR 33178) (FRL-4869-1). As indicated in the proposed HAPs test rule, EPA would use the data obtained from testing to implement several provisions of section 112 of the Clean Air Act (CAA), including the determination of residual risk, the estimation of the risks associated with accidental releases of chemicals, and determinations whether substances should be removed from the CAA section 112(b)(1) list of hazardous air pollutants (delisting). The data also would be used by other Federal agencies (e.g. Agency for Toxic Substances and Disease Registry (ATSDR), National Institute of Occupational Safety and Health (NIOSH), Occupational Safety and Health Administration (OSHA), and Consumer Product Safety Commission (CPSC)) in assessing chemical risks and in taking appropriate actions within their programs. In the proposed HAPs test rule, EPA invited the submission of proposals for pharmacokinetics (PK) studies for the HAPs chemicals, which could provide the basis for negotiation of ECAs. These PK studies would be used to inform EPA about the use of route-to-route extrapolation of toxicity data from routes other than inhalation to predict the effects of inhalation exposure, as an alternative to testing proposed under the HAPs test rule. EPA received a PK proposal for ethylene glycol from the Chemical Manufacturers Association, Ethylene Glycol Panel (CMA EG Panel) on November 5, 1996. Based on the PK proposal received for ethylene glycol, the Agency developed a preliminary technical analysis. A copy of this preliminary technical analysis was sent to the CMA EG Panel on August 26, 1997. The CMA EG Panel reviewed EPA's analysis and notified EPA on October 6, 1997 that it has a continued interest in pursuing the ECA process. A copy of the PK proposal, the EPA preliminary technical analysis and related references, and correspondence is contained in the public record for this ECA process. These materials will be used during discussions at the negotiating meeting. EPA has decided to proceed with the ECA process for ethylene glycol and is providing public notice that the Agency is hereby initiating the procedures for ECA negotiations for the HAP chemical, ethylene glycol. The procedures for ECA negotiations are described at 40 CFR 790.22(b). EPA intends to publish, as appropriate, additional Federal Register documents to solicit interested parties and announce public meetings for other HAPs chemicals for which PK proposals were submitted. The proposed HAPs test rule, as amended on December 24, 1997 (62 FR 67466) (FRL-5742-2), and the ECA negotiations on chemicals included in the proposed rule are separate and parallel activities. While the Agency's objective of obtaining data could be accomplished by either activity, EPA recognizes that the final testing program performed by industry may differ depending on whether it is accomplished under the final HAPs test rule or via the ECA process. During the course of ECA negotiations, additional information may be brought forward that could cause the Agency to re-evaluate the nature of the testing requirements as stated in the proposed HAPs test rule, as amended. This could result in the development of an ECA that would fulfill the Agency's data needs in ways not stated in the proposed HAPs test rule, as amended. It is therefore essential for all interested parties to recognize these differences at the outset and respond accordingly within the framework of these two separate and parallel activities. Comments on the proposed HAPs test rule, as amended, must be submitted under docket control number, OPPTS-42187A, as described in the proposed HAPs test rule published on June 26, 1996, as amended on December 24, 1997, and will be addressed by EPA via the rulemaking process, which is separate and distinct from the ECA process. Participation in the ECA process is described in Units II. through IV. of this document. Negotiations on developing an ECA for the HAP chemical, ethylene glycol, will focus on the use of PK studies and mechanistic data to help meet testing requirements for ethylene glycol. In addition, discussion will include the adequacy of the available data base to be used for extrapolation to obtain the data needs identified for ethylene glycol in the proposed HAPs test rule, as amended. The objective of the ECA process is to conclude an ECA that will set in place an industry- sponsored testing program that will adequately address EPA's data needs for ethylene glycol. III. Identification of Interested Parties EPA is soliciting interested parties to monitor or participate in testing negotiations on an ECA for ethylene glycol. The CMA EG Panel, the submitter of the PK proposal for ethylene glycol, and the member companies of the CMA EG Panel are already considered interested parties and do not need to respond to this document. Additionally, any persons who respond to this document on or before February 11, 1998 will be given the status of interested parties. Interested parties must respond in writing to the address specified in the ``ADDRESSES'' at the beginning of this document. These interested parties will not incur any obligations by being so designated. Negotiations will be conducted in one or more meetings [[Page 3113]] open to the public. The negotiation time schedule for ethylene glycol will be established at the first negotiation meeting and will not exceed a period of 4 months from the initial meeting. If an ECA is not established in principle within this timeframe and EPA does not choose to extend the negotiation time period, negotiations will be terminated and testing will be required under the final HAPs test rule. If the testing from the ECA does not meet the Agency's needs, EPA reserves the right to enter into rulemaking. IV. Public Participation in Negotiations Under EPA regulations, the Agency is required to provide the public with an opportunity to comment on and participate in the development of ECAs. The procedural rule for ECAs (40 CFR part 790) contains provisions to ensure that the views of interested parties are taken into account during the ECA process. Individuals and groups who respond to this document will have the status of interested parties. All negotiating meetings for the development of this ECA for ethylene glycol will be open to the public and minutes of each meeting will be prepared by EPA and placed in the public docket for this ECA process. The Agency will advise interested parties of meeting dates and make available meeting minutes, testing proposals, background documents, and other materials exchanged at or prepared for negotiating meetings. Where tentative agreement is reached on an acceptable testing program, a draft ECA will be made available for comment by interested parties and, if necessary, EPA will hold a public meeting to discuss any comments that have been received and determine whether revisions to the ECA are appropriate. EPA will not reimburse costs incurred by non-EPA participants in this ECA negotiation process. ECAs will only be concluded where an agreement can be obtained which is satisfactory to the Agency, manufacturers or processors who are potential test sponsors, and other interested parties, concerning the need for and scope of testing. In the absence of an ECA, EPA reserves the right to proceed with rulemaking. A. The Agency will not enter into an ECA if either: 1. EPA and affected manufacturers or processors cannot reach an agreement on the provisions of the ECA; or 2. The draft ECA is considered inadequate by other interested parties who have submitted timely written objections to the draft ECA. B. EPA may reject these objections if the Agency concludes either that: 1. They are not made in good faith; 2. They are untimely; 3. They are not related to the adequacy of the proposed testing program or other features of the agreement that may affect EPA's ability to fulfill the goals and purposes of TSCA; or 4. They are not accompanied by a specific explanation of the grounds on which the draft agreement is considered objectionable. EPA will prepare an explanation of the basis for each ECA. The explanatory document will summarize the agreement (including the required testing), explain the objectives of the testing, and outline the chemical's use and exposure characteristics. The document, which will also announce the availability of the ECA, will be published in the Federal Register. V. Proposal of Export Notification Requirements for Ethylene glycol EPA intends to publish a proposed rule in an upcoming Federal Register document to require export notification by all persons who export or intend to export ethylene glycol under TSCA section 12(b) upon the successful conclusion of an ECA for ethylene glycol. VI. Public Record and Electronic Submissions As described above, ethylene glycol is listed as a chemical that would be subject to testing requirements under the proposed HAPs test rule, as amended. This ECA negotiation process and the proposed rule, as amended, are separate and parallel activities. The official record for this ECA action, including the public version, has been established under docket control number OPPTS-42202B (including comments and data submitted electronically as described below).
