Definitions

In this Act: (1) Community with environmental justice concerns The term community with environmental justice concerns means a community with significant representation of communities of color, low-income communities, or Tribal and indigenous communities, that experiences, or is at risk of experiencing, higher or more adverse human health or environmental effects as compared to other communities. (2) Extreme heat The term extreme heat means heat that substantially exceeds local climatological norms in terms of any combination of the following: (A) Duration. (B) Intensity. (C) Season length. (D) Frequency. (3) Heat The term heat means any combination of the atmospheric parameters associated with modulating human thermoregulation, such as air temperature, humidity, solar exposure, and wind speed. (4) Heat event The term heat event means an occurrence of extreme heat of 2 days or more that may have heat-health implications. (5) Heat-health The term heat-health means health effects to humans from heat, during or outside of heat events, including from vulnerability and exposure, or the risk of such effects. (6) Indian tribe The term Indian Tribe has the meaning given that term in section 4 of the Indian Self-Determination and Education Assistance Act (25 U.S.C. 5304). (7) Native hawaiian organization The term Native Hawaiian organization has the meaning given that term in section 6207 of the Elementary and Secondary Education Act of 1965 (20 U.S.C. 7517). (8) Planning The term planning means activities performed across timescales (including days, weeks, months, years, and decades) with scenario-based, probabilistic or deterministic information to identify and take actions to proactively mitigate heat-health risks from increased frequency, duration, and intensity of heat waves and increased ambient temperature. (9) Preparedness The term preparedness means activities performed across timescales (including days, weeks, months, years, and decades) with decision support tools to manage risk in advance of a heat event and increased ambient temperature. (10) Response The term response means activities performed during and after a heat event to address heat-health and other impacts and assess improvements to planning and preparedness activities. (11) Urban heat island The term urban heat island means the phenomenon observed in urbanized areas in which heat is more extreme than in the surrounding exurban areas and heat is heterogeneously distributed within urbanized areas, due to factors including— (A) low albedo and impervious surfaces; (B) low vegetation coverage; and (C) waste heat produced in urban areas.
