Approval and Promulgation of Air Quality Implementation Plans; Maryland; Maryland's Negative Declaration for the Automobile and Light-Duty Truck Assembly Coatings Control Techniques Guidelines
The Environmental Protection Agency (EPA) is approving a State Implementation Plan (SIP) revision submitted by the State of Maryland. This revision pertains to a negative declaration for the Automobile and Light-Duty Truck Assembly Coatings Control Techniques Guidelines (CTG). EPA is approving this revision in accordance with the requirements of the Clean Air Act (CAA).
California State Nonroad Engine Pollution Control Standards; Small Off-Road Engines Regulations; Tier 4 Off-Road Compression-Ignition Regulations; Exhaust Emission Certification Test Fuel for Off-Road Spark-Ignition Engines, Equipment, and Vehicles Regulations; Notice of Decision
The Environmental Protection Agency (EPA) is confirming that the California Air Resources Board's (CARB's) 2011 amendments to its Small Off-Road Engines (SORE) regulations (2011 SORE amendments), Tier 4 Off-Road Compression-Ignition (CI) regulations (2011 Tier 4 amendments), and Exhaust Emission Certification Test Fuel for Off-Road Spark-Ignition (SI) Engines, Equipment, and Vehicles regulations (2011 Certification Test Fuel amendments) are within the scope of previous EPA authorizations. The 2011 SORE amendments modify California's existing SORE test procedures by aligning California procedures to be consistent with recent amendments by EPA to the federal certification and exhaust emission testing requirements. The 2011 Tier 4 amendments enhance the harmonization of CARB's exhaust emission requirements for new off-road CI engines with the corresponding federal emissions requirements for nonroad CI engines. The 2011 Certification Test Fuel amendments modify the certification test fuel requirements for off-road spark ignition, gasoline-fueled engines to allow the use of 10-percent ethanol-blend gasoline (E10) as a certification fuel. This decision is issued under the authority of the Clean Air Act (``CAA'' or ``Act'').
Request for Nominations to the National Advisory Council for Environmental Policy and Technology (NACEPT)

Approval and Promulgation of State Plans for Designated Facilities; Commonwealth of Puerto Rico
The Environmental Protection Agency (EPA) is proposing to approve the State plan submitted by the Commonwealth of Puerto Rico to implement and enforce the Emission Guidelines (EG) for existing sewage sludge incineration (SSI) units. Puerto Rico's plan is consistent with the EG promulgated by the EPA on March 21, 2011. Puerto Rico's plan establishes emission limits and other requirements for the purpose of reducing toxic air emissions and other air pollutants from existing SSI units throughout the Commonwealth. At the request of Puerto Rico, the EPA is proposing not to take action on a provision of its SSI plan allowing for affirmative defenses of Clean Air Act violations in the case of malfunctions. Puerto Rico submitted its plan to fulfill the requirements of sections 111(d) and 129 of the Clean Air Act.
Air Plan Approval; Minnesota; Transportation Conformity Procedures
The Environmental Protection Agency (EPA) is approving a State Implementation Plan (SIP) revision for carbon monoxide (CO), submitted by the State of Minnesota on July 16, 2015. The purpose of this revision is to establish transportation conformity criteria and procedures related to interagency consultation, and enforceability of certain transportation related control and mitigation measures.

Air Plan Approval and Air Quality Designation; SC; Redesignation of the Charlotte-Rock Hill, 2008 8-Hour Ozone Nonattainment Area to Attainment
The Environmental Protection Agency (EPA) is taking three separate final actions related to a state implementation plan (SIP) revision submitted by the State of South Carolina, through the South Carolina Department of Health and Environmental Control (SC DHEC), on April 17, 2015. These final actions are for the York County, South Carolina portion of the bi-state Charlotte-Rock Hill, North Carolina- South Carolina 2008 8-hour ozone national ambient air quality standards (NAAQS) nonattainment area (the entire area is hereinafter referred to as the ``bi-State Charlotte Area'' or ``Area'' and the South Carolina portion is hereinafter referred to as the ``York County Area''). In these three final actions, EPA determines that the bi-state Charlotte Area is continuing to attain the 2008 8-hour ozone NAAQS; approves and incorporates South Carolina's plan for maintaining attainment of the 2008 8-hour ozone standard in the York County Area, including the 2014 and 2026 motor vehicle emission budgets (MVEBs) for nitrogen oxides (NOX) and volatile organic compounds (VOC) for the York County Area, into the SIP; and redesignates the York County Area to attainment for the 2008 8-hour ozone NAAQS. Additionally, EPA finds the 2014 and 2026 MVEBs for the York County Area adequate for the purposes of transportation conformity.
Revisions to the Unregulated Contaminant Monitoring Rule (UCMR 4) for Public Water Systems and Announcement of a Public Meeting
The U.S. Environmental Protection Agency (EPA) is proposing a Safe Drinking Water Act (SDWA) rule that requires public water systems to collect occurrence data for contaminants that may be present in tap water but are not yet subject to EPA's drinking water standards set under SDWA. This rule, revised every five years as required by SDWA, benefits public health by providing EPA and other interested parties with scientifically valid data on the national occurrence of selected contaminants in drinking water, such as cyanotoxins associated with harmful algal blooms. This data set is one of the primary sources of information on occurrence, levels of exposure and population exposure the Agency uses to develop regulatory decisions for emerging contaminants in the public drinking water supply. This proposal identifies eleven analytical methods to support water system monitoring for a total of 30 chemical contaminants/groups, consisting of ten cyanotoxins/groups; two metals; eight pesticides plus one pesticide manufacturing byproduct (hereinafter collectively referred to as ``pesticides''); three brominated haloacetic acid groups of disinfection byproducts; three alcohols; and three semivolatile organic chemicals. EPA is also announcing a public webinar to discuss this proposal of the fourth Unregulated Contaminant Monitoring Rule.
