Air Plan Approval; Guam; Clean Data Determination for the Piti-Cabras Nonattainment Area for the 2010 1-Hour Sulfur Dioxide National Ambient Air Quality Standard
The Environmental Protection Agency (EPA) is proposing a clean data determination (CDD) for the Piti-Cabras, Guam sulfur dioxide (SO2) nonattainment area ("Piti-Cabras area") based on our determination that the area has attained the 2010 1-hour SO2 National Ambient Air Quality Standard (NAAQS, "standard," or "2010 SO2 NAAQS"). In designated nonattainment areas where air quality data demonstrate that a NAAQS has been attained, the EPA interprets certain requirements of the Clean Air Act (CAA) as no longer applicable for so long as air quality continues to meet the standard. Under this Clean Data Policy, the EPA may issue a determination of attainment, known as a CDD, that a nonattainment area is attaining the relevant NAAQS. If finalized, this proposed CDD would suspend the obligation to submit certain attainment planning requirements for the Piti-Cabras area for as long as the area continues to attain the 2010 SO2 NAAQS or until the area is formally redesignated.

Hazardous Waste Management System; Identification and Listing of Hazardous Waste; Final Rule
The Environmental Protection Agency (EPA) is granting a petition submitted by WRB Refining in Borger, Texas to exclude (or "delist") 7,000 cubic yards of F037 (petroleum refinery sludge) solids to be removed from their stormwater storage tanks for a one-time delisting. This determination is based on information the petitioner provided to the Agency, completion of sampling, and risk assessment using the Delisting Risk Assessment Software (DRAS) to determine whether the waste poses a substantial present or potential hazard to human health or the environment when improperly treated, stored, transported or disposed of, or otherwise managed. This final rule responds to a petition submitted by WRB Refinery to exclude stormwater solids from the definition of a hazardous waste. If not delisted, the stormwater solids are listed as F037 (primary oil/water/solids separation sludge). After careful analysis of the petition and evaluation of comments submitted by the public, the EPA has concluded that the petitioned waste is not hazardous waste when disposed of in Subtitle D landfills. This exclusion applies to the stormwater solids generated at WRB Refinery Borger, Texas facility. Accordingly, this final rule excludes the petitioned waste from the requirements of hazardous waste regulations under the Resource Conservation and Recovery Act (RCRA) when disposed of in a Subtitle D landfill but imposes testing conditions to ensure that the future-generated waste remain qualified for delisting.
