As part of the administration’s initiative to cut federal red tape, the Department of Energy announced May 26 a delay of the effective date of two regulations as it attempts to ease its testing requirements for determining the efficiency of equipment. Manufacturers of commercial heating, ventilating, and air conditioning equipment, commercial refrigeration and water heating equipment, walk-in coolers and freezers, and automatic commercial ice makers may be given an additional 18 months to comply with the certification requirements. The agency will also provide a grace period of two years before enforcing new enforcement guidance on water conservation standards for shower heads. Proposed changes in the use of categorical exclusions under the National Environmental policy Act would add solar, wind, and other alternative energy sources to the list of activities that can be excluded from requirements for environmental impact statements.
