 AGENCY: Environmental Protection Agency (EPA).
 ACTION: Notice.
 SUMMARY: This document announces the second list of chemicals and substances for which EPA intends to issue test orders under the Endocrine Disruptor Screening Program (EDSP). EPA established the EDSP in response to section 408(p) of the Federal Food, Drug, and Cosmetic Act (FFDCA). This second list of chemicals expands the EDSP in an effort to include all pesticides, required by FFDCA, and adds priority drinking water chemicals into the program for screening as authorized by SDWA section 1457. Today's publication provides public notice of EPA's tentative decision-making in advance of the actual issuance of EDSP testing orders.
 DATES: In order for the Agency to consider information and/or comments that may be relevant to the inclusion or exclusion of chemicals contained on the second EDSP list, this information and/or comments should be received by EPA on or before December 17, 2010.

Today's document announces the second list of chemicals that the Agency intends to include in its EDSP. Through the issuance of orders, the Agency intends to require the submission of Tier 1 Screening data for these chemicals. Elsewhere in today's issue of the 
                    **Federal Register**
                    , EPA also is announcing the policies and procedures expected to be followed for certain chemicals on this list. Information on EDSP and Tier 1 Screening data is 
                    ( print page 70250)
                    available on the Agency's Web site at 
                    *http://www.epa.gov/​endo.* B. What is the agency's authority for taking this action? EPA's authority for taking this action is based on several different Congressional actions, including FFDCA, the Safe Drinking Water Act (SDWA), and the House Appropriations Committee report for EPA's FY 2010 appropriations. EPA developed the EDSP in 1998 to implement FFDCA section 408(p), which requires EPA to “develop a screening program, using appropriate validated test systems and other scientifically relevant information, to determine whether certain substances may have an effect in humans that is similar to an effect produced by a naturally occurring estrogen, or such other endocrine effect as [EPA] may designate.” (21 U.S.C. 346a(p)). The statute generally requires EPA to “provide for the testing of all pesticide chemicals” and gives EPA discretionary authority to “provide for the testing of any other substance that may have an effect that is cumulative to an effect of a pesticide chemical if the Administrator determines that a substantial population may be exposed to such a substance.” (21 U.S.C. 346a(p)(3)). The statute also authorizes EPA to exempt a chemical upon a determination that “the substance is anticipated not to produce any effect in humans similar to an effect produced by a naturally occurring estrogen.” (21 U.S.C. 346a(p)(4)). Section 1457 of SDWA provides that “in addition to the substances” referred to in FFDCA section 408(p)(3)(B), “the Administrator may provide for testing under the screening program authorized by section 408(p) of such Act, in accordance with the provisions of section 408(p) of such Act, of any other substance that may be found in sources of drinking water if the Administrator determines that a substantial population may be exposed to such substance.” (42 U.S.C. 300j-17). EPA used its authority under SDWA to identify a portion of the chemicals on the second EDSP list. In addition, in Congress's House Appropriations Committee report for EPA's FY 2010 appropriations (H.R. 2996, H. Rept. 111-180) (Ref. 1), it directed EPA “to publish within 1 year of enactment a second list of no less than 100 chemicals for screening that includes drinking water contaminants, such as halogenated organic chemicals, dioxins, flame retardants (PBDEs, PCBs, PFCs), plastics (BPA), pharmaceuticals and personal care products, and issue 25 orders per year for the testing of these chemicals.” III. Background EPA developed EDSP in response to a Congressional mandate in FFDCA “to determine whether certain substances may have an effect in humans that is similar to an effect produced by a naturally occurring estrogen, or such other endocrine effect as [EPA] may designate” (21 U.S.C. 346a(p)). As part of EDSP, EPA issues orders to collect certain test data on listed chemical substances. Unit II.B. describes the authority for listing a chemical. Test data requirements are derived from specific test assays, which are divided into two tiers. Tier I test assays are used to screen the chemicals for interaction with the estrogen (E), androgen (A) or thyroid (T) hormonal systems. Tier II test assays are intended to test for more specific chemical effects on the endocrine system, and are currently in the process of being developed and validated. Further information regarding EDSP and requirements for Tier I and Tier II can be found on the Agency's EDSP Web site, at 
                    *http://www.epa.gov/​endo/​.* IV. Development of the Second EDSP List In developing the second EDSP list, EPA focused on a subset of chemicals and substances that have been listed as priorities within EPA's drinking water and pesticides programs. While the Agency has not included some chemicals or substances on the second EDSP list as explained in Unit IV.A., non-inclusion does not mean that these other chemicals or substances may not be subject to testing in the near term nor in the future. In addition, based on current information, the public should not presume that the listing of a chemical or substance indicates in any way that EPA currently suspects that such chemical or substance interferes with the endocrine systems of humans or other species simply because it has been listed for screening under the EDSP. At the present time, EPA believes that these chemicals or substances should be candidates, at least for screening purposes, under EDSP testing based only on their pesticide registration status and/or because such substances may occur in sources of drinking water to which a substantial population may be exposed. A. Basis for Chemical Selection The Agency considered chemicals contained on the Office of Water (OW) and Office of Pesticide Programs (OPP) priority lists for inclusion on the second EDSP list. 1. 
                    *Initial compilation of OW candidate chemicals.*
                     The Agency identified candidate chemicals that are either contaminants regulated with a national primary drinking water regulation (NPDWR) (40 CFR part 141) (Ref. 2) or are unregulated contaminants that are listed on the third Contaminant Candidate List (CCL 3) (USEPA, 2009) (Ref. 3). EPA began with the 85 regulated drinking water contaminants with existing NPDWRs and the 116 unregulated contaminants listed on CCL 3 because these represent many of the priority contaminants for the drinking water program. Most of the regulated drinking water contaminants with NPDWRs were designated by Congress under the 1986 or the1996 SDWA amendments. Because Congress designated these contaminants for regulation due to concerns about occurrence in drinking water and adverse impacts on human health, EPA believes that each such substance meets the statutory testing criteria from SDWA section 1457. SDWA section 1412(b)(9) requires the Agency to periodically review the existing NPDWRs and revise them, if appropriate. Information about the potential for endocrine disruption will assist the Agency in updating human health assessments, which the Agency considers in its periodic review of NPDWRs to ensure that they are protective of human health. SDWA section 1412(b)(1) requires the Agency to develop a list of unregulated contaminants that are known or anticipated to occur in public water systems (PWSs) and may require regulation under SDWA. The Agency is required to develop the CCL list every 5 years. In determining whether a substance may occur in drinking water, EPA considers not only public water system monitoring data, but also data on ambient concentrations in surface water and ground water, and releases to the environment (e.g., reporting data from the Toxics Release Inventory). The Agency believes that such data are sufficient to anticipate contaminants that may occur in public water systems and furthermore, also represent those substances that may be found in sources of drinking water and to which a substantial population may be exposed. In selecting contaminants for the CCL, SDWA section 1412(b)(1)(C) requires that the Agency “take into consideration, among other factors of public health concern, the effect of such contaminants upon subgroups that comprise a meaningful portion of the general population (such as infants, children, pregnant women, the elderly, 
                    ( print page 70251)
                    individuals with a history of serious illness, or other subpopulations) that are identifiable as being at greater risk of adverse health effects due to exposure to contaminants in drinking water than the general population.” The protocol that EPA used to develop CCL 3 was reviewed by internal experts, as well as external experts such as the National Drinking Water Advisory Council and the Science Advisory Board (Ref. 3). The CCL 3 has undergone a rigorous listing and expert review process, including a public nomination and comment period, and therefore, represent an excellent source of potential drinking water candidates to consider for EDSP screening. The information about the potential for endocrine disruption will assist the Agency in evaluating the human health impacts of unregulated drinking water contaminants. In the CCL listing, EPA already has made the component of the SDWA section 1457 determination that such substances may occur in sources of drinking water. The final CCL 3 listing also represents EPA's determination that a substantial population may be exposed to such substance for the purposes of SDWA 1457. In listing drinking water contaminants on the CCL 3, EPA closely evaluated the nature of the occurrence and prevalence information supporting each such CCL 3 listing. Evaluating occurrence, EPA considered and evaluated data based on occurrence in finished drinking water and ambient water, as well as based on total releases to the environment, pesticide application rates, and production volumes (73 FR 9628, February 21, 2008) (FRL-8529-7). In deciding whether to move a possible drinking water contaminant from the preliminary CCL 3 to the proposed CCL 3, EPA scored each such contaminant based on, among other attributes, its occurrence attributes (at 73 FR 9640-41, February 21, 2008). The occurrence attributes were weighted more heavily based on a hierarchy representing prevalence of the contaminant in the water environment or likely release to the water environment. The results of that scoring are described at 73 FR 9644, February 21, 2008. The administrative record supporting the CCL 3 ultimately published in 2009 includes contaminant-by-contaminant information sheets that document the occurrence data upon which EPA relied for the listing of CCL 3 contaminants. The basis for EPA's inclusion of the CCL 3 contaminants on its tentative testing list, therefore, also provides the basis for EPA's determination that a substantial population may be exposed to each such substance for the purposes of SDWA section 1457. 2. 
                    *Initial compilation of OPP candidate chemicals.*
                     The Agency identified candidate chemicals from OPP based on pesticides that were scheduled for Registration Review during fiscal years 2007 and 2008. This selection is part of the Agency's intent to efficiently expedite the testing of pesticides by conducting the testing in parallel or as part of the OPP Registration Review program. 3. 
                    *Streamlining the second EDSP list.*
                     Consolidating the lists of OW and OPP chemicals resulted in over 200 chemicals. A listing of these chemicals is available in the docket for this notice (Ref. 4). The Agency streamlined this initial second EDSP list by excluding any chemical that fell into one or more of the following categories: i. Biological agent and naturally occurring chemicals (
                    *e.g.,*
                     microbials, microbial toxins, inorganics, radionuclides). ii. Chemicals for which the manufacturer, importer or registrant cannot be clearly identified (
                    *e.g.,*
                     disinfection byproducts or DBPs, microbes, microbial toxins, degradate compounds with more than one possible source). iii. Chemicals already included on the first EDSP list because these chemicals have already received an EDSP order. Note however that if no one agreed to provide data in response to that order, additional orders may be issued under a SDWA determination. iv. Chemicals that are hormones with confirmed endocrine effects. v. Chemicals not likely to be biologically active or which are incompatible with testing assays for various reasons due to one or more of their physiochemical properties (
                    *e.g.,*
                     gases, strongly acidic or basic, solubility, vapor pressure molecular weight). vi. Pesticides that are scheduled for registration review after FY 2008. Although these chemicals have been excluded from the second EDSP list for one or more of these reasons, it is important to note that these exclusions do not imply that the Agency has no interest in the potential for endocrine disruption activity for these chemicals. In some instances, the Agency recognizes that information on endocrine effects is already available (
                    *e.g.,*
                     for the hormones) or the Agency is currently collecting information (
                    *e.g.,*
                     through the first EDSP list). In other cases, the Agency simply realizes that at this time there is some difficulty with collecting the information about endocrine effects through the EDSP (
                    *i.e.,*
                     because of the Agency's inability to identify a manufacturer, importer, or registrant or because the contaminant is incompatible with the testing assays). In addition, EPA recognizes that some of the naturally occurring chemicals also have anthropogenic sources and should be considered for the EDSP. In no way should it be inferred that removal from this initial second EDSP list signifies that a chemical does not have the potential to be placed on a future EDSP chemical list. The Agency intends to reexamine currently excluded chemicals for future EDSP chemical lists. EPA is interested in receiving information from the public that may help the Agency resolve the difficulties with the currently excluded chemicals so that the Agency will be able to consider adding them to future EDSP chemical lists. B. Second EDSP List of Chemicals There are approximately 134 chemicals on the second ESDP list (see Table 1). This list includes a large number of pesticides, two perfluorocarbon compounds (PFCs), and three pharmaceuticals (erythromycin, nitroglycerin, and quinoline). This list also consists of an array of other chemicals, ranging from those used for industrial manufacturing processes, as plasticizers, or in the production of pharmaceutical and personal care products (PPCPs). EPA is interested in receiving information and/or comment that may inform the exclusion or inclusion of chemicals on the second EDSP list. The Agency does not plan to respond formally to information or comments that may be submitted on this document, but will add such information to the notice docket as public record. EPA will consider such information and/or comment before finalizing the second EDSP list and publishing the Schedule for Issuance of Orders along with the second EDSP list. In addition, please note that by relying on the CCL 3 as part of this effort, the Agency does not intend to re-open CCL 3 for public comment or any of the individual lists used to create the second list of EDSP chemicals and does not intend to respond to any such comments so submitted.
