March 17, 2021 – Federal Register Recent Federal Regulation Documents

The U.S. Environmental Protection Agency (EPA or Agency) is initiating further data collection and analysis to support potential future rulemaking, under the Clean Water Act (CWA), relating to the effluent limitations guidelines, pretreatment standards and new source performance standards applicable to the Organic Chemicals, Plastics and Synthetic Fibers (OCPSF) point source category to address discharges from manufacturers of per- and polyfluoroalkyl substances (PFAS) and is considering revising the same for formulators of PFAS. PFAS are a group of man-made organic chemicals. Some PFAS compounds are persistent in the environment and in the human body. Analysis of animal studies and human epidemiological research suggest that exposure above certain levels to some PFAS may be associated with adverse human health effects. The Agency has identified several industries with facilities that are likely to be discharging PFAS in their wastewater, including OCPSF manufacturers and formulators. This advance notice of proposed rulemaking (ANPRM) provides for public review and comment on the information and data regarding PFAS manufacturers and formulators that EPA has collected to date. EPA is requesting public comment on the information and data presented in this ANPRM. EPA is also soliciting additional information and data regarding discharges of PFAS from these facilities to inform future revisions to the wastewater discharge requirements that apply to the OCPSF point source category.

These special conditions are issued for the Leonardo S.p.A. (Leonardo) Model A119 and AW119 MKII helicopters. These helicopters as modified by AgustaWestland Philadelphia Corporation (AWPC) will have a novel or unusual design feature when compared to the state of technology envisioned in the airworthiness standards for helicopters. This design feature is the optional closed circuit refueling receiver (CCRR). The applicable airworthiness regulations do not contain adequate or appropriate safety standards for this design feature. These special conditions contain the additional safety standards that the Administrator considers necessary to establish a level of safety equivalent to that established by the existing airworthiness standards.

The FAA proposes to adopt a new airworthiness directive (AD) for all Bombardier, Inc., Model CL-600-1A11 (600), CL-600-2A12 (601), and CL-600-2B16 (601-3A, 601-3R and 604 Variants) airplanes. This proposed AD was prompted by reports of corrosion on the passenger door internal structure of in-service airplanes. This proposed AD would require revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations. The FAA is proposing this AD to address the unsafe condition on these products.
