Environmental Protection Agency April 9, 2008 – Federal Register Recent Federal Regulation Documents

This regulation establishes an amendment to an exemption from the requirement of a tolerance for residues of the 1-Methylcyclopropene (1-MCP) on fruits and vegetables when applied or used outdoors for pre- harvest treatments. Agrofresh Inc., submitted a petition to EPA under the Federal Food, Drug, and Cosmetic Act (FFDCA), as amended by the Food Quality Protection Act of 1996 (FQPA), requesting an amendment to the existing 1-MCP exemption from the requirement of a tolerance at 40 CFR 180.1220. This regulation eliminates the need to establish a maximum permissible level for residues of 1-Methylcyclopropene.

This regulation establishes tolerances for residues of buprofezin in or on berry, low growing , subgroup 13-07G; okra; olive; olive, oil; pepper, nonbell; radicchio; vegetable, fruiting, group 8, except nonbell pepper; and vegetable, leafy, except Brassica, group 4, except head lettuce and radicchio; and increases the existing tolerance for residues of buprofezin in or on head lettuce. Interregional Research Project Number 4 (IR-4) requested these tolerances under the Federal Food, Drug, and Cosmetic Act (FFDCA). This regulation also removes existing tolerances for residues of buprofezin in or on leaf lettuce and tomato and modifies 40 CFR 180.511 by removing the third column (Expiration/Revocation Date) from the table in paragraph (a), since it is no longer applicable.

The Environmental Protection Agency is proposing to amend and consolidate in one place the federal drinking water requirements (known as National Primary Drinking Water Regulations or NPDWRs) for aircraft public water systems under the Safe Drinking Water Act (SDWA). Aircraft public water systems are subject to the requirements of SDWA and the NPDWRs. The existing federal drinking water standards were primarily designed to regulate water quality in stationary public water systems and the application of these requirements to mobile water systems with the capability of flying throughout the world has created implementation challenges. The proposed requirements are intended to tailor existing health-based drinking water standards to the unique characteristics of aircraft public water systems for the enhanced protection of public health against illnesses attributable to microbiological contamination. This is accomplished through multiple- barrier protection and procedural control measures. EPA believes that the combination of these components will better protect public health while building upon existing aircraft operations and maintenance programs, better coordinate federal programs that regulate aircraft water systems, and minimize disruption of aircraft flight schedules.
