The public workshop will be held at the U.S. Department of Energy, Room 1E-245, 1000 Independence Avenue, SW, Washington, DC 20585. FOR FURTHER INFORMATION CONTACT: Mr. Bryan Berringer, U.S. Department of Energy, Office of Energy Efficiency and Renewable Energy, Forrestal Building, Mail Stop EE-43, 1000 Independence Avenue, SW., Washington, DC 20585-0121, (202) 586- 0371; or Ms. Sandy Beall, Office of Energy Efficiency and Renewable Energy, U.S. Department of Energy, Mail Stop EE-43, 1000 Independence Avenue, SW., Washington, DC 20585-0121, (202) 586-7574. SUPPLEMENTARY INFORMATION: On March 23, 1995, the Department of Energy published a notice of Proposed Rule and Public Hearing on proposed amendments to clarify the water heater; kitchen range, oven, and microwave; and clothes washer test procedures. (60 FR 15330, March 23, 1995) The notice requested data and comments until the close of comment period on August 31, 1995 (Docket No: EE-RM-94-230). A public hearing was held on July 12, 1995. The Department is convening a public workshop for water heaters to discuss the large number of comments received on the notice and from the public hearing. The Department seeks to gather additional information and/or data on certain unresolved issues being considered by the Department in its development of the Final Rule for Water Heater Test Procedure. The tentative topics and issues to be discussed at the February 12, 1997, public workshop include the following: 1. First Hour Rating for Storage-Type Water HeatersShould DOE consider the 1979 test method (44 FR 52632, September 7, 1979) for measuring first hour rating? Should DOE retain the current test method (55 FR 42162, October 17, 1990) for measuring first hour rating? Should DOE adopt the 1995 proposed test method (60 FR 15330, March 23, 1995) for measuring first hour rating (with revision to include a temperature correction factor of 120 deg.F for each draw if an internal mixing device is used)? Should DOE adopt the alternate test method proposed by Dr. Carl Hiller of Electric Power Research Institute (EPRI) (EE-RM-94-230, No. 17)? 2. Instantaneous water heaters Do oil-fired instantaneous water heaters exist in the marketplace, and, if so, should test procedures be developed for them? Should test procedures be developed for single point-of- use type electric instantaneous water heaters? Should DOE adopt an alternate first-hour rating method for instantaneous water heaters using a maximum draw rate at a temperature rise of 77 deg.F as proposed by Gas Appliance Manufacturers Association (GAMA) (EE-RM-94-230, No. 1 & 35), or a temperature rise of 50 deg.F as proposed by Edison Electric Institute (EEI) (EE-RM-94-230, No. 2 & 27) and EPRI (EE-RM-94-230, No. 17)? 3. Storage-type water heaters with rated storage capacities of less than 20 gallons Should test procedures developed for storage-type water heaters be applied to storage-type water heaters with rated storage capacities of less than 20 gallons? If so, should the draw rate and daily draw volume in ASHRAE Standard 118.2--1993, as referenced in the 1995 DOE proposed rule, be used in the 24-hour simulated use test for storage-type water heaters with rated storage capacities of less than 20 gallons? Or should some other draw rate and total daily drawn volume be used? Should test procedures be developed for storage-type water heaters with rated storage capacities of less than 10 gallons (single point-of-use type heaters)? 4. Daily hot water usage Does the daily usage assumed in the current test procedures, 64.3 gallons, reflect realistic daily hot water usage, and if not, what volume should it be? How will the Energy Factor be affected if testing were conducted at a daily hot water usage volume other than 64.3 gallons? 5. Thermostat settings Should the current setting of 135 deg.F be lowered to 120 deg.F to reflect manufacturers' recommendation that thermostat setting be set at a lower setting to avoid potential scalding? How will the Energy Factor be effected if testing were conducted at a thermostat setting of 120 deg.F? 6. Test procedures for heat pump water heaters Does the current test procedure (draw schedule of six hourly draws of 10.7 gallons per draw) provide operating conditions which would allow the resistance element(s) to be activated? Should DOE consider an alternate draw schedule to be used in the 24-hr simulated use test for heat pump water heaters and if so, what should this draw schedule be? How will the Energy Factor be effected if testing were conducted using different alternate draw schedules? 7. Definitions for heat pump water heaters, add-on heat pump water heaters, integral heat pump water heaters, solar water heaters, and heat pump water heater storage tanks Should any of the proposed definition be adopted by DOE? Should any proposed definition be revised and if so, which one(s) and how should it (they) be revised? Which, if any proposed definition should be completely deleted? After completion of the workshop, the Department will review all of the findings and other recommendations. The Department will use this information to develop the final rule for the water heater test procedures. The workshop will be professionally facilitated. Please notify Mr. Bryan Berringer at the above listed address of your [[Page 4203]] intention to attend the workshop, or if you wish to be added to the DOE mailing list for receipt of future rules and information concerning water heater matters relating to energy efficiency. Issued in Washington, DC on January 22, 1997. Christine A. Ervin, Assistant Secretary, Energy Efficiency and Renewable Energy. [FR Doc. 97-2173 Filed 1-28-97; 8:45 am] BILLING CODE 6450-01-P
