Comprehensive Environmental Response, Compensation, and Liability Act; Proposed Administrative Settlement Agreement for Recovery of Response Costs; “Delta Shipyard” Superfund Site in Houma, Terrebonne Parish, LA
In accordance with the Comprehensive Environmental Response, Compensation, and Liability Act (``CERCLA''), notice is hereby given that a proposed administrative settlement agreement for recovery of response costs (``Proposed Agreement'') associated with the ``Delta Shipyard'' Superfund Site in Houma, Terrebonne Parish, Louisiana (``Site'') was executed by the Environmental Protection Agency (``EPA'') and is now subject to public comment, after which EPA may modify or withdraw its consent if comments received disclose facts or considerations that indicate that the Proposed Agreement is inappropriate, improper, or inadequate.
National Emission Standards for Hazardous Air Pollutants: Carbon Black Production Residual Risk and Technology Review and Carbon Black Production Area Sources Technology Review
The U.S. Environmental Protection Agency (EPA) is proposing amendments to the National Emission Standards for Hazardous Air Pollutants (NESHAP) for the Carbon Black Production major source category. The proposal addresses the results of the residual risk and technology review (RTR) for this source category as required under the Clean Air Act (CAA). The proposed amendments address hazardous air pollutant (HAP) emissions that occur after the main unit filter of a carbon black production unit, as well as emissions from boilers and process heaters. The proposed amendments also address the startup, shutdown, and malfunction (SSM) provisions of the existing standards, and would require electronic reporting of certain notifications, performance test results, and semiannual reports. Additionally, the proposal addresses the results of the technology review for the Carbon Black Production Area Source NESHAP.
National Emission Standards for Hazardous Air Pollutants: Refractory Products Manufacturing Residual Risk and Technology Review
The U.S. Environmental Protection Agency (EPA) is proposing amendments to address the results of the residual risk and technology review (RTR) that the EPA is required to conduct in accordance with the Clean Air Act (CAA) with regard to the National Emissions Standards for Hazardous Air Pollutants (NESHAP) for Refractory Products Manufacturing. The EPA is proposing to find the risks due to emissions of air toxics from this source category under the current standards to be acceptable and that the standards provide an ample margin of safety to protect public health. We are proposing no revisions to the existing numerical emission limits based on these analyses; however, we are proposing new provisions for certain hazardous air pollutants (HAP). The EPA is also proposing to amend provisions addressing emissions during periods of startup, shutdown, and malfunction (SSM) and provisions addressing emissions during periods of scheduled maintenance; to amend provisions regarding electronic reporting of performance test results; and to make miscellaneous clarifying and technical corrections.
