The Department of Veterans Affairs (VA) is issuing this interim final rule (IFR) to amend its adjudication regulations to establish presumptive service connection for acute leukemias, chronic leukemias, multiple myelomas, myelodysplastic syndromes (MDS), and myelofibrosis due to exposure to Particulate Matter 2.5 (PM<INF>2.5</INF>). The new presumptions would apply to veterans who served on active military, naval, air, or space service in the Southwest Asia theater of operations or Somalia during the Persian Gulf War (hereafter Gulf War) on or after August 2, 1990, and in Afghanistan, Syria, Djibouti, Uzbekistan, Egypt, Jordan, Lebanon, and Yemen during the Gulf War on or after September 11, 2001.
