[alpha]lpha-Alkyl-[omega]-Hydroxypoly (Oxypropylene) and/or Poly (Oxyethylene) Polymers Where the Alkyl Chain Contains a Minimum of Six Carbons etc.; Exemption From the Requirement of a Tolerance
This regulation establishes an exemption from the requirement of a tolerance for residues of [alpha]-alkyl-[omega]-hydroxypoly (oxypropylene) and/or poly (oxyethylene) polymers where the alkyl chain contains a minimum of six carbons, and [alpha]-alkyl-[omega]- hydroxypoly (oxypropylene) and/or poly (oxyethylene) polymers where the alkyl chain contains a minimum of six carbons and a minimum number average molecular weight (in amu) 1,100 (hereinafter referred to as ``AAAs'' (alkyl alcohol alkoxylates) when used as an inert ingredient as a surfactant in pesticide formulations in growing crops without limitations. Akzo Nobel Surface Chemistry submitted a petition to EPA under the Federal Food, Drug, and Cosmetic Act (FFDCA), requesting an amendment to an existing requirement of a tolerance. This regulation eliminates the need to establish a maximum permissible level for residues of AAAs.
Uniform National Discharge Standards for Vessels of the Armed Forces-Phase II
The U.S. Environmental Protection Agency (EPA) and the U.S. Department of Defense (DoD) are proposing performance standards for certain discharges incidental to the normal operation of a vessel of the Armed Forces into the navigable waters of the United States, the territorial seas, and the contiguous zone. The proposed standards would reduce the adverse environmental impacts associated with the discharges, stimulate the development of improved pollution control devices, and advance the development of environmentally sound ships by the Armed Forces. The proposed standards are designed to be consistent with the effluent limitations included in the recently issued National Pollutant Discharge Elimination System (NPDES) general permit for discharges incidental to the normal operation of a non-military vessel.
Standards of Performance for New Residential Wood Heaters, New Residential Hydronic Heaters and Forced-Air Furnaces, and New Residential Masonry Heaters
The EPA is proposing to amend the Standards of Performance for New Residential Wood Heaters and to add two new subparts: Standards of Performance for New Residential Hydronic Heaters and Forced-Air Furnaces and Standards of Performance for New Residential Masonry Heaters. This proposal is aimed at achieving several objectives for new residential wood heaters and other wood-burning appliances, including applying updated emission limits that reflect the current best systems of emission reduction; eliminating exemptions over a broad suite of residential wood combustion devices; strengthening test methods as appropriate; and streamlining the certification process. This proposal does not include any requirements for heaters solely fired by gas, oil or coal. In addition, it does not include any requirements associated with appliances that are already in use. The EPA continues to encourage state, local, tribal, and consumer efforts to changeout (replace) older heaters with newer, cleaner, more efficient heaters, but that is not part of this federal rulemaking. Particulate pollution from wood heaters is a significant national air pollution problem and human health issue. Health benefits associated with these proposed regulations are valued to be much greater than the cost to manufacture cleaner, lower emitting appliances. These proposed regulations would significantly reduce particulate matter (PM) emissions and many other pollutants from these appliances, including carbon monoxide (CO), volatile organic compounds (VOC), and hazardous air pollutants (HAP). Emissions from wood stoves occur near ground level in residential communities across the country, and setting these new requirements for cleaner stoves into the future will result in substantial reductions in exposure and improved public health.
