### 81052 Federal Register / Vol. 81, No. 222 / Thursday, November 17, 2016 / Proposed Rules

IV. What analysis and data are being noticed?

1. EPA is seeking comment on the following updates to the chlorpyrifos human health risk assessment: (1) Use of the crack and crevice scenario to derive an exposure level for women in the Columbia study; (2) using the LOAEL from the Columbia study and PBPK modeling to derive an endpoint for use in quantitative risk assessment; (3) use of the 10X uncertainty factor for intraspecies variability; (4) use of the 10X FQPA safety factor for LOAEL to NOAEL extrapolation (please include your rationale for any alternative values suggested for this factor). Its analysis is included in the Chlorpyrifos: Revised Human Health Risk Assessment for Registration Review (2016), which is available in the chlorpyrifos tolerance revocation docket (EPA–HQ–OPP– 2015–0653).

2. EPA is also making available for comment the issue paper and associated materials presented to the April 2016 FIFRA SAP and the final report of the SAP. The FIFRA SAP materials and final report are available in the FIFRA SAP docket (EPA–HQ–OPP–2016– 0062).

3. EPA is also seeking comment on Chlorpyrifos Registration Review Drinking Water Assessment, a highly refined drinking water assessment that updates and completes the agency’s examination of exposure through drinking water for all registered uses of chlorpyrifos. This assessment integrates regionally specific ( i.e., spatially relevant) estimated drinking water concentrations and an extensive evaluation of available surface water monitoring data for chlorpyrifos and chlorpyrifos-oxon. The assessmentconsiders both agricultural and nonagricultural uses of chlorpyrifos, a sensitivity analysis for model estimated concentrations, and statistical evaluation of surface water monitoring data.

**AGENCY :**  Environmental Protection Agency (EPA).

**ACTION :**  Proposed rule.

**SUMMARY :**  Nebraska has applied to the Environmental Protection Agency (EPA) for final authorization of revisions to its hazardous waste program under the Resource Conservation and Recovery Act (RCRA). EPA is proposing to grant final authorization to Nebraska.

. The EPA may publish any comment received to its public docket. Do not submit electronically any information you consider to be Confidential Business Information (CBI) or other information whose disclosure is restricted by statute. Multimedia submissions (audio, video, etc.) must be accompanied by a written comment.

. **SUPPLEMENTARY INFORMATION :**  In the final rules section of the Federal Register , EPA is authorizing the revisions by a direct final rule. EPA did not make a proposal prior to the direct final rule because we believe this action is not controversial and do not expect comments that oppose it. We have explained the reasons for this authorization in the preamble of the direct final rule. If no relevant adverse comments are received in response to this action, no further activity is contemplated in relation to this action. If EPA receives relevant adverse comments, the direct final rule will be withdrawn and all public comments received will be addressed in a subsequent final rule based on this proposed action. EPA will not institute a second comment period on this action. Any parties interested in commenting on this action should do so at this time. Please note that if EPA receives adverse comment on part of this rule and if that part can be severed from the remainder of the rule, EPA may adopt as final those parts of the rule that are not the subject of an adverse comment. For additional information, see the direct final rule which is located in the rules section of this Federal Register
