Clean Water Act; Contractor Access to Confidential Business Information
The Environmental Protection Agency (EPA) intends to transfer confidential business information (CBI), collected from numerous industries, to ICF International (ICF) and its subcontractors and consultants, under an EPA contract newly awarded to ICF. Transfer of this information is necessary for ICF to assist the Office of Water in the preparation of economic analyses and environmental assessment activities conducted in support of Clean Water Act regulations and programs, such as effluent guidelines and associated planning and review activities, and water quality standards. Much of the information being transferred was or will be collected under the authority of section 308 of the Clean Water Act (CWA) to support effluent guidelines development in particular. Interested persons may submit comments on this intended transfer of information to the address noted below.
Hazardous Waste Management System; Identification and Listing of Hazardous Waste
The Environmental Protection Agency (EPA) is granting a petition submitted by Blanchard Refining Company LLC(Blanchard) to exclude (or delist) the residual solids generated from the reclamation of oil bearing hazardous secondary materials (OBSMs) on-site at Blanchard's Galveston Bay Refinery (GBR), located in Texas City, Texas from the lists of hazardous wastes. EPA used the Delisting Risk Assessment Software (DRAS) Version 3.0.35 in the evaluation of the impact of the petitioned waste on human health and the environment. The residual solids are listed as F037 (primary oil/water/solids separation sludge) when they are reclaimed from the OBSMs. After careful analysis and evaluation of comments submitted by the public, the EPA has concluded that the petitioned wastes are not hazardous waste when disposed of in Subtitle D landfills. This exclusion applies to the residuals solids generated at Blanchard's Galveston Bay Refinery (GBR), located in Texas City, 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 Subtitle D landfills but imposes testing conditions to ensure that the future-generated wastes remain qualified for delisting.
Release of Risk and Exposure Assessment Plan for the Secondary National Ambient Air Quality Standard for Oxides of Nitrogen, Oxides of Sulfur and Particulate Matter
The Environmental Protection Agency (EPA) is conducting a periodic review of the air quality criteria and the secondary National Ambient Air Quality Standards (NAAQS) for oxides of nitrogen, oxides of sulfur, and particulate matter (PM). On or about August 6, 2018, the EPA will make available for public review the document titled Review of the Secondary National Ambient Air Quality Standards for Oxides of Nitrogen, Oxides of Sulfur and Particulate Matter: Risk and Exposure Assessment Planning Document (REA Planning Document). This plan presents considerations and the proposed approach for conducting quantitative analyses of oxides of nitrogen, oxides of sulfur, and PM exposures and welfare risks in this NAAQS review. This planning document is intended to facilitate consultation with the Clean Air Scientific Advisory Committee (CASAC) and public comment on plans for such quantitative analyses.
