  • Notice of Adjustments to Service Obligations
    Served: May 12, 2020 UNITED STATES OF AMERICA DEPARTMENT OF TRANSPORTATION OFFICE OF THE SECRETARY WASHINGTON, D.C. CONTINUATION OF CERTAIN AIR SERVICE PURSUANT TO PUBLIC LAW NO. 116-136 §§ 4005 AND 4114(b) Docket DOT-OST-2020-0037 NOTICE OF ADJUSTMENTS TO SERVICE OBLIGATIONS Summary By this notice, the U.S. Department of Transportation (the Department) announces an opportunity for incremental adjustments to service obligations under Order 2020-4-2, issued April 7, 2020, in light of ongoing challenges faced by U.S. airlines due to the Coronavirus (COVID-19) public health emergency. With this notice as the initial step, the Department will use a systematic process to allow covered carriers1 to reduce the number of points they must serve as a proportion of their total service obligation, subject to certain restrictions explained below.2 Covered carriers must submit prioritized lists of points to which they wish to suspend service no later than 5:00 PM (EDT), May 18, 2020. DOT will adjudicate these requests simultaneously and publish its tentative decisions for public comment before finalizing the point exemptions. As explained further below, every community that was served by a covered carrier prior to March 1, 2020, will continue to receive service from at least one covered carrier. The exemption process in Order 2020-4-2 will continue to be available to air carriers to address other facts and circumstances. Background On March 27, 2020, the President signed the Coronavirus Aid, Recovery, and Economic Security Act (the CARES Act) into law. Sections 4005 and 4114(b) of the CARES Act authorize the Secretary to require, “to the extent reasonable and practicable,” an air carrier receiving financial assistance under the Act to maintain scheduled air transportation service as the Secretary deems necessary to ensure services to any point served by that air carrier before March 1, 2020.

  • Building Energy Asset Score Program Overview and Technical Protocol
    PNNL-22045 Rev. 1.2 Prepared for the U.S. Department of Energy under Contract DE-AC05-76RL01830 Building Energy Asset Score Program Overview and Technical Protocol (Version 1.2) N Wang S Goel V Srivastava A Makhmalbaf September 2015 PNNL-22045 Rev. 1.2 Building Energy Asset Score Program Overview and Technical Protocol (Version 1.2) N Wang S Goel V Srivastava A Makhmalbaf September 2015 Prepared for the U.S. Department of Energy under Contract DE-AC05-76RL01830 Pacific Northwest National Laboratory Richland, Washington 99352 Summary The U.S. Department of Energy (DOE) is developing a voluntary national scoring system for commercial and multi-family residential buildings to help building owners and managers assess a building’s energy-related systems independent of operations. The goal of the score is to encourage cost- effective investment in energy efficiency improvements for these types of buildings. The system, known as the Building Energy Asset Score, will allow building owners and managers to compare their building infrastructure against peers and track energy efficiency impacts of building upgrades over time. The system will also help other building stakeholders (e.g., building investors, tenants, financiers, and appraisers) understand the relative efficiency of different buildings in a way that is independent from operations and occupancy. Prior to developing the Asset Score, DOE performed a market study1 to ensure that the effort would help address market needs and fill identified gaps. In 2012, DOE began initial pilot testing of the Asset Score. In 2013, DOE continued to assess the Asset Score through additional pilot testing and a variety of technical evaluations and performance analyses.

  • Design Temperature Limit Reference Guide (2019 Edition)
    ENERGY STAR Single-Family New Homes ENERGY STAR Multifamily New Construction Design Temperature Limit Reference Guide (2019 Edition) These 2019 Edition limits are permitted to be used with any National HVAC Design Report, and are required to be used for all National HVAC Design Reports generated on or after 10-01-2020 Introduction One requirement of the ENERGY STAR Single-Family New Homes and Multifamily New Construction (MFNC) programs is to use outdoor design temperatures that do not exceed the maximum cooling season temperature and minimum heating season temperature listed in this reference guide for the state and county, or territory, in which the home is to be certified. Only two exceptions apply: 1. Jurisdiction-Specified Temperatures: If the outdoor design temperatures to be used in load calculations are specified by the jurisdiction where the home will be certified, then these specified temperatures shall be used. 2. Temperature Exception Request: In rare cases, the designer may believe that an exception to the limits in the reference guide are warranted for a particular state and county, or territory. If so, the designer must complete and submit a Design Temperature Exception Request, including a justification for the exception, to [email protected] for review and approval prior to the home’s certification. To obtain the most accurate load calculations, EPA recommends that designers always use the ACCA Manual J, 8th edition, 1% cooling season design temperature and 99% heating season design temperature for the weather location that is geographically closest to the home to be certified. How to Use this Reference Guide 1.

  • Shrinking Ponds in Subarctic Alaska Based on 1950–2002 Remotely Sensed Images Brian Riordan,1 David Verbyla,1 and A
    JOURNAL OF GEOPHYSICAL RESEARCH, VOL. 111, G04002, doi:10.1029/2005JG000150, 2006 Click Here for Full Article Shrinking ponds in subarctic Alaska based on 1950–2002 remotely sensed images Brian Riordan,1 David Verbyla,1 and A. David McGuire1,2 Received 5 December 2005; revised 2 June 2006; accepted 20 June 2006; published 10 October 2006. [1] Over the past 50 years, Alaska has experienced a warming climate with longer growing seasons, increased potential evapotranspiration, and permafrost warming. Research from the Seward Peninsula and Kenai Peninsula has demonstrated a substantial landscape-level trend in the reduction of surface water and number of closed-basin ponds. We investigated whether this drying trend occurred at nine other regions throughout Alaska. One study region was from the Arctic Coastal Plain where deep permafrost occurs continuously across the landscape. The other eight study regions were from the boreal forest regions where discontinuous permafrost occurs. Mean annual precipitation across the study regions ranged from 100 to over 700 mm yrÀ1. We used remotely sensed imagery from the 1950s to 2002 to inventory over 10,000 closed-basin ponds from at least three periods from this time span. We found a reduction in the area and number of shallow, closed-basin ponds for all boreal regions. In contrast, the Arctic Coastal Plain region had negligible change in the area of closed-basin ponds. Since the 1950s, surface water area of closed-basin ponds included in this analysis decreased by 31 to 4 percent, and the total number of closed-basin ponds surveyed within each study region decreased from 54 to 5 percent.
