Washington State Department of Ecology Prohibition of Discharges of Vessel Sewage; Receipt of Petition and Preliminary Affirmative Determination
Notice is given that, pursuant Clean Water Act Section 312(f)(3), the Washington State Department of Ecology has determined that the protection and enhancement of the quality of the waters of Puget Sound requires greater environmental protection, and has petitioned the United States Environmental Protection Agency, Region 10, for a determination that adequate facilities for the safe and sanitary removal and treatment of sewage from all vessels are reasonably available for those waters, so that the State may completely prohibit the discharge from all vessels of any sewage, whether treated or not, into such waters. Washington State has proposed to establish a ``No-Discharge Zone'' (NDZ) for all marine waters of Washington State inward from the line between New Dungeness Lighthouse and the Discovery Island Lighthouse to the Canadian border, and fresh waters of Lake Washington, Lake Union, and connecting waters between and to Puget Sound. The western boundary of the NDZ would be the exit of the Strait of Juan de Fuca near the entrance of Admiralty Inlet. This boundary is known and visible to vessel operators as it is the line between New Dungeness Lighthouse and Discovery Island Lighthouse. The northern boundary would be the border with Canada and heading south including all marine waters down to the south end of the south Sound and Hood Canal. The fresh waters of Lake Washington, Union Bay, Montlake Cut, Portage Bay, Lake Union, Fremont Cut, the Lake Washington Ship Canal, and Salmon Bay (the connecting waters from Lake Washington to Puget Sound) would be included. For more information regarding the State's planned NDZ, please go to http://www.ecy.wa.gov/programs/wq/nonpoint/ CleanBoating/nodischargezone.html. Today's notice seeks public comment on EPA's tentative determination that adequate facilities for the safe and sanitary removal and treatment of sewage from all vessels are reasonably available for the waters subject to Washington's planned NDZ.
Approval and Promulgation of Air Quality Implementation Plans; Maryland; Revisions and Amendments to Regulations for Continuous Opacity Monitoring, Continuous Emissions Monitoring, and Quality Assurance Requirements for Continuous Opacity Monitors
The Environmental Protection Agency (EPA) is approving a state implementation plan (SIP) revision submitted by the State of Maryland. The revision pertains to changes and amendments to Maryland regulations for continuous opacity monitoring (COM or COMs) and continuous emissions monitoring (CEM or CEMs) and to an amendment adding requirements for Quality Assurance and Quality Control (QA/QC) as they pertain to COMs. EPA is approving these revisions to the COMs and CEMs requirements in accordance with the requirements of the Clean Air Act (CAA).

Approval of Air Quality Implementation Plans; Puerto Rico; Attainment Demonstration for the Arecibo Lead Nonattainment Area
The Environmental Protection Agency is proposing to approve a State Implementation Plan dated August 30, 2016, submitted by the Commonwealth of Puerto Rico to the EPA, for the purpose of providing for attainment of the 2008 Lead National Ambient Air Quality Standards in the Arecibo Lead nonattainment area. The Arecibo nonattainment Area is comprised of a portion of Arecibo Municipality in Puerto Rico with a 4 kilometer radius surrounding The Battery Recycling Company, Inc. Puerto Rico initially submitted a lead SIP revision for the Arecibo area on January 30, 2015. The EPA proposed to disapprove the January 30, 2015 submittal on February 29, 2016. The PREQB rescinded the January 30, 2015 submittal and replaced it with the August 30, 2016 lead SIP submittal for the Arecibo area.
Air Plan Approval; NH; Rules for Reducing Particulate Emissions
The Environmental Protection Agency (EPA) is approving State Implementation Plan (SIP) revisions submitted by the State of New Hampshire on March 31, 2011 and on July 23, 2013. These SIP revisions establish particulate matter (PM) and visible emissions (VE) standards for the following sources: foundries, smelters, and investment casting operations; hot mix asphalt plants; and sand and gravel sources, non- metallic mineral processing plants, and cement and concrete sources. In addition, EPA is approving a part of a SIP revision submitted by New Hampshire on March 12, 2003 that establishes procedures for testing opacity of emissions (i.e., VE). This action is being taken under the Clean Air Act.
Rescission of Preconstruction Permits Issued Under the Clean Air Act
The Environmental Protection Agency (EPA) is promulgating amendments to the EPA's federal Prevention of Significant Deterioration (PSD) regulations to remove a date restriction from the Permit Rescission provision. Other than removing the date restriction, this final rule does not alter the criteria under which a new source review (NSR) permit may be rescinded. This final rule also clarifies that a rescission of a permit is not automatic and corrects an outdated cross- reference to another part of the PSD regulations. The EPA is also adding a corresponding Permit Rescission provision in the federal regulations that apply to major sources in nonattainment areas of Indian country.
