The New York State Department of Conservation (NYSDEC) on behalf of the New York City Department of Environmental Protection (NYCDEP) has proposed to establish a Vessel Waste No Discharge Zone (NDZ) for the Bay that covers an area of approximately 20,000 acres (17,177 acres of open water and 2,695 acres of upland islands and salt marshes). It is bounded on the west and northwest by Brooklyn, and on the north and northeast by Queens. The northeastern and southeastern corners of the Bay are bordered by Nassau County. The northern shore of the Rockaway Peninsula, a part of Queens, forms the southern boundary. The Bay is connected to the Atlantic Ocean PO 00000 Frm 00037 Fmt 4703 Sfmt 4703 66927 through the Rockaway Inlet and has a tidal range of approximately 5 to 6 feet. The NYSDEC certified the need for greater protection of the water quality. EPA hereby makes a final affirmative determination that adequate facilities for the safe and sanitary removal and treatment of sewage from all vessels are reasonably available for the Bay. EPA published a tentative affirmative determination on August 3, 2011 in the Federal Register. Public comments were solicited for 30 days and the comment period ended on September 2, 2011. EPA received a total of twenty (25) comments via letter and email. The comment tally was twenty-three (23) in favor of, and two (2) questioning or opposing, the No Discharge Zone designation. All the relevant comments received have been considered in the final affirmative determination. This Federal Register document will address all comments submitted in response to the August 3, 2011 (Volume 76 Issue 149) Federal Register document. Response to Comments 1. Comment: Twenty-three commenters including boaters, paddlers, kayakers, non-governmental organizations, and community advocates expressed strong support for EPA’s action to establish a vessel waste no discharge zone for the Bay. Some commenters pointed out that this action will reduce pathogens and chemicals, improve water quality and further protect and restore the Bay. EPA Response: EPA is in full agreement that designating the Bay is an important step to further protect this valuable natural resource, water quality, wetlands and habitats throughout the entire the Bay area. 2. Comment: One commenter stated that discharges from several small tugs with the required Marine Sanitation Devices (MSDs) are a relatively small source of pollution compared to the pollution caused by 1,200 to 1,500 of recreational vessels that utilized the Bay. EPA Response: These comments go beyond the scope of EPA’s authority in this action. Because EPA’s authority here is limited to determining whether adequate pumpout facilities exist, it cannot base its determination on whether commercial vessel sewage is comparable in quantity or impact to other sources of pollution, or whether banning such discharges is otherwise unfair to commercial boaters. However, it is noted that the sewage discharged from MSDs is treated with chlorine, quaternary ammonia and formaldehyde, which can all pose threats to the marine environment, especially if present in E:\FR\FM\28OCN1.SGM 28OCN1

II. Background

    The purpose of this notice is to extend the public comment period 
on the EPA's recently posted draft non-binding guidance titled, 
``Guidance for 1-Hour SO2 SIP Submissions.'' The comment 
period notice published in the Federal Register on October 3, 2011 at 
76 FR 61098. The original comment period is scheduled to expire on 
November 2, 2011. By this notice, the EPA is extending the comment 
period for an additional 30 days resulting in the comment period ending 
on December 2, 2011. The EPA is extending the comment period due to 
public requests that have been made stating that additional time is 
required in order to fully evaluate the guidance and provide 
substantive comment.
    While the EPA is providing additional time for the public to submit 
comments on the draft guidance, we are also taking into consideration 
that there is a need to finalize the guidance as quickly as possible so 
that states, tribes, and air agencies have the necessary information to 
begin work on their State Implementation Plans submittals to address 1-
hour SO2 NAAQS. We are therefore working to assure that the 
delays that result from this extension of the comment period on the 
draft guidance are kept to a minimum. In

addition, as stated in the draft guidance, the EPA is also currently 
drafting a proposed rulemaking on specific elements of the draft 
guidance concerning the elements necessary for the section 110(a)(1) 
maintenance plan submittal. Since these two documents are linked in 
terms of issues involved, the EPA will be taking into consideration the 
comments that will be received on the draft guidance in making 
decisions concerning each document.
    The draft of the guidance document is available online at https://www.epa.gov/airquality/sulfurdioxide/implement.html or within the 
associated docket, EPA-HQ-OAR-2010-1059.
