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 assessment 

considers both agricultural and nonagricultural uses of chlorpyrifos, a 

sensitivity analysis for model estimated 

concentrations, and statistical 

evaluation of surface water monitoring 

data.

[EPA–R07–RCRA–2016–0637; FRL–9955– 

24-Region 7] 

State of Nebraska; Authorization of 

State Hazardous Waste Management 

Program 

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. 

DATES: Comments on this proposed 

action must be received in writing by 

December 19, 2016. 

ADDRESSES: Submit your comments, 

identified by Docket ID No. EPA–R07– 

RCRA–2016–0637, to http://

www.regulations.gov. Follow the online 

instructions for submitting comments. 

Once submitted, comments cannot be 

edited or removed from Regulations.gov. 

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. 

The written comment is considered the 

official comment and should include 

discussion of all points you wish to 

make. The EPA will generally not 

consider comments or comment 

contents located outside of the primary 

submission (i.e. on the web, cloud, or 

other file sharing system). For 

additional submission methods, the full 

EPA public comment policy, 

information about CBI or multimedia 

submissions, and general guidance on

Haugen, EPA Region 7, Enforcement 

Coordination Office, 11201 Renner

address: haugen.lisa@epa.gov. 

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. 

Dated: November 3, 2016.

Regional Administrator, Region 7.
