Environmental Protection Agency October 9, 2012 – Federal Register Recent Federal Regulation Documents

EPA is proposing to update a portion of the Outer Continental Shelf (``OCS'') Air Regulations. Requirements applying to OCS sources located within 25 miles of States' seaward boundaries must be updated periodically to remain consistent with the requirements of the corresponding onshore area (``COA''), as mandated by section 328(a)(1) of the Clean Air Act, as amended in 1990 (``the Act''). The portions of the OCS air regulations that are being updated pertain to the requirements for OCS sources by the Ventura County Air Pollution Control District (Ventura County APCD). The intended effect of approving the OCS requirements for the Ventura County APCD is to regulate emissions from OCS sources in accordance with the requirements onshore. The change to the existing requirements discussed below is proposed to be incorporated by reference into the Code of Federal Regulations and is listed in the appendix to the OCS air regulations.

EPA is taking final action to approve the State Implementation Plan (SIP) submissions, submitted by the State of Mississippi, through the Mississippi Department of Environmental Quality (MDEQ), as demonstrating that the State meets portions of the SIP requirements of sections 110(a)(1) and (2) of the Clean Air Act (CAA or Act) for the 1997 annual and 2006 24-hour fine particulate matter (PM2.5) national ambient air quality standards (NAAQS). Section 110(a) of the CAA requires that each state adopt and submit a SIP for the implementation, maintenance, and enforcement of each NAAQS promulgated by the EPA, which is commonly referred to as an ``infrastructure'' SIP. MDEQ certified that the Mississippi SIP contains provisions that ensure the 1997 annual and 2006 24-hour PM2 NAAQS are implemented, enforced, and maintained in Mississippi (hereafter referred to as ``infrastructure submissions''). With the exception of sections 110(a)(2)(D)(i), 110(a)(2)(E)(ii) and 110(a)(2)(G), each of which will be addressed in separate actions, Mississippi's infrastructure submissions, provided to EPA on December 7, 2007, and October 6, 2009, address all the required infrastructure elements for the 1997 annual and 2006 24-hour PM2 NAAQS.

EPA is proposing to amend the definition of heating oil in the Renewable Fuel Standard (RFS) program under section 211(o) of the Clean Air Act. This amendment would expand the scope of renewable fuels that can generate Renewable Identification Numbers (RINs) as heating oil to include fuel oil produced from qualifying renewable biomass that would be used to generate heat to warm buildings or other facilities where people live, work, recreate, or conduct other activities. Fuel oils used to generate process heat, power, or other functions would not be included in the amended definition. Producers or importers of fuel oil that meets the amended definition of heating oil would be allowed to generate RINs, provided that the fuel oil meets the other requirements specified in the RFS regulations. This proposed amendment would not modify or limit fuel included in the current definition of heating oil. We are also proposing amendments to the diesel sulfur program to provide additional flexibility for transmix processors that produce locomotive and marine diesel fuel. Specifically, we are proposing to reinstate an allowance for transmix processors to produce 500 parts per million (ppm) sulfur diesel fuel for use in older technology locomotive and marine diesel outside of the Northeast Mid-Atlantic Area. We are also requesting comment on extending this allowance to outside of the Northeast Mid-Atlantic Area. These proposed amendments to the diesel transmix provisions are expected to result in reduced compliance costs for transmix processors and users of locomotive and marine diesel fuel while having a neutral or positive environmental impact. EPA is also proposing to amend the fuel marker requirements for 500 ppm sulfur locomotive and marine (LM) diesel fuel to address an oversight in the original rulemaking where the regulations failed to incorporate provisions described in the rulemaking preamble to allow for solvent yellow 124 marker to transition out of the distribution system.

The Environmental Protection Agency (EPA) is issuing a final Federal Implementation Plan (FIP) to address regional haze in the State of Hawaii. This FIP addresses the requirements of the Clean Air Act (CAA or ``the Act'') and EPA's rules concerning reasonable progress towards the national goal of preventing any future and remedying any existing man-made impairment of visibility in mandatory Class I areas in the State of Hawaii. The FIP establishes an emissions cap of 3,550 tons of sulfur dioxide (SO2) per year from three specific fuel oil-fired, electric utility boilers on the Island of Hawaii beginning in 2018. The Hawaii Electric Light Company (HELCO) can minimize impacts on the ratepayers by meeting the cap through the increased use of renewable energy and energy conservation. EPA finds that this control measure, in conjunction with other emissions control requirements that are already in place, will ensure that reasonable progress is made during this first planning period toward the national goal of no man-made visibility impairment by 2064 at Hawaii's two Class I areas. EPA worked closely with the State of Hawaii in the development of this plan and the State has agreed to incorporate the control requirements into the relevant permits. The State has indicated that it intends to take full responsibility for the development of future Regional Haze plans.
