§ 334.784 East Pearl River, within the 
acoustic buffer area of the John C. Stennis Space Center, and adjacent to lands, in Hancock County, Mississippi; danger zone. 
(a) The area. A danger zone is 
established in and to the extent of 
waters of the United States, as defined in 33 CFR part 329, in the following reaches of the East Pearl River south of a point, on the left descending bank, located at latitude 30.4030° N., 
longitude ¥89.6815° W., to a point 
below the confluence of Mikes River, located at latitude 30.3561° N., 
longitude ¥89.6514° W. The datum is 
NAD83. 
(b) The regulation. (1) No person, 
vessel, or other watercraft, other than a vessel owned and operated by the United States, shall enter or remain in the danger zone, or within a portion or portions thereof, when closed to public access, as provided in paragraph (b)(2) of this section, below, except by permission of Commander, Naval Construction Battalion Center, Gulfport or such other person(s) as he or she may designate. 
(2) The danger zone, or a portion or 
portions thereof, will be closed, for riverine, weapons, or other dangerous naval training, by placement of Government picket boats at the northern and southern boundaries in the East Pearl River, or at such other location(s) within the danger zone as may be determined to be sufficient to protect the public. Prior to closure, picket boats will transit the area(s) to be closed, to ensure that no persons, vessels, or other watercraft are present. Once the danger zone, or location(s) within the zone, has been cleared, picket boats will remain in position, upstream and downstream, until it is safe to re-open the area(s) to public access. 
(3) Riverine, weapons, and other 
dangerous naval training may occur on any day of the week, typically, but not exclusively, in periods of two to eight hours, between 6 a.m. and 6 p.m. Training may occur at night, in darkness. 
(c) Enforcement. The restrictions on 
public access in this section shall be enforced by Commander, Naval Construction Battalion Center, Gulfport or by such other person(s) as he or she may designate. Dated: December 1, 2016.

Notice of Data Availability Concerning 
the Renewables Enhancement and Growth Support Rule 
AGENCY : Environmental Protection 
Agency (EPA). 
ACTION : Notice of data availability. 
SUMMARY : This Notice provides an 
opportunity to comment on new information that pertains to the proposed provisions for ethanol flex fuel contained in the Renewables Enhancement and Growth Support (REGS) rule which was published in the Federal Register on November 16, 2016. The new information is contained in the report titled ‘‘Property Analysis of Ethanol—Natural Gasoline—BOB Blends to Make Flex Fuel’’ that has been placed in the public docket for this action. In the proposed REGS rule, the EPA proposed volatility standards for ethanol flex fuel (EFF) to prevent excessive evaporative emissions that could adversely affect the emissions control systems of flexible fuel vehicles (FFVs) and human health. The EPA proposed a fuel volatility compliance tool for use by regulated entities to demonstrate compliance with the proposed volatility standards for EFF. The new information being made available by this notice indicates that the proposed compliance tool may need to be modified to adequately estimate the volatility of EFF when natural gasoline is used as a blendstock. 
DATES : Comments. Comments must be 
received on or before January 17, 2017.

2In the REGS rule, EPA is proposing that all EFF 
blends that contain 16 to 83 volume percent ethanol 
(E16–E83) would be subject to the same set of regulatory controls rather than continuing to treat E16–E50 blends as gasoline. E85 is a trade name that has historically been used for blends that contain 51 to 83 volume percent ethanol (E51–E83). 3SAE technical paper 2007–01–4006, ‘‘A Model

II. Request for Comment A. Background 
In the Renewables Enhancement and 
Growth Support (REGS) Rule,
1EPA is 
proposing enhancements to its 
Renewable Fuel Standards (RFS) program and other related fuel regulations to support market growth of ethanol and other renewable fuels in the U.S. These proposed changes will provide the opportunity for increasing the production and use of renewable fuels by allowing the market to operate in the most efficient and economical way to introduce greater volumes of renewable fuels under the program. The proposed provisions for ethanol flex fuel (EFF)
2in the REGS rule would 
provide additional flexibility to use natural gasoline as an EFF blendstock while maintaining the environmental performance of these fuels. The use of lower cost natural gasoline to make EFF may reduce the price to consumers of these fuels, thereby encouraging the use of additional ethanol and furthering the goals for the RFS program. B. Request for Comment 
To support the use of natural gasoline 
as an EFF blendstock while meeting the EPA’s evaporative emission control and public health protection goals, the EPA proposed that a fuel volatility compliance tool could be used to demonstrate compliance with the proposed volatility standards for EFF. The proposed compliance tool was based on a fuel volatility model that was developed using data on the volatility of gasoline—ethanol fuel blends.
3This 
fuel volatility model, which is well accepted by industry, is used to estimate the volatility of ethanol blends made with gasoline and/or blendstock for oxygenate blending.
4At proposal, we 
explained why we believed that the proposed compliance tool would also be a satisfactory means of estimating ethanol blend volatility when natural gasoline is used as a blendstock even though we only had limited data that evaluated its suitability for this purpose. In sum, we reasoned that blendstock for oxygenate blending and natural gasoline blend linearly and would thus, behave as a single component in compliance tool calculations. The report that this notice adds to the docket for the REGS proposed rule, and for which we seek public comment, contains the results of a test program that compares empirical data on E51–83 blend volatility when natural gasoline is used as a blendstock to the volatility estimated by the proposed compliance tool.
5These test 
data in this report indicate that the proposed compliance tool may significantly underestimate the volatility of some higher level ethanol blends when natural gasoline is used as a blendstock. These data, therefore, contradict the assumption that blendstock for oxygenate blending and natural gasoline blend linearly and behave as a single component in compliance tool calculations. The report also suggests that other aspects of the final blend may need to be taken into account for the compliance tool to provide a satisfactory estimate of ethanol blend volatility when natural gasoline is used as a blendstock. The EPA requests comment on all aspects of this report and the proposed fuel volatility compliance tool as well as how it might be modified to better estimate the effect of natural gasoline on the volatility of ethanol fuel blends. The EPA will consider the information contained in the report made available by this notice and the resulting public comments from this notice in developing a final rule from the REGS proposed rule.

Petition 012—Atherosclerosis; Finding of Insufficient Evidence 
AGENCY : Centers for Disease Control and 
Prevention, HHS. 
ACTION : Denial of petition for addition of 
a health condition. 
SUMMARY : On April 11, 2016, the 
Administrator of the World Trade Center (WTC) Health Program received two petitions (combined into Petition 012) to add atherosclerosis to the List of WTC-Related Health Conditions (List). The Program conducted a literature search for the term in response to the Petition and found no relevant studies regarding atherosclerosis among 9/11- exposed populations. Accordingly, the Administrator finds that insufficient evidence exists to request a recommendation of the WTC Health Program Scientific/Technical Advisory Committee (STAC), to publish a proposed rule, or to publish a
