This document discusses the EPA's use of infrastructure data for emergency response efforts. It notes that the EPA's emergency response has traditionally focused on oil and hazardous waste cleanup after disasters. However, the poor quality of drinking water and wastewater infrastructure data hampered the EPA's response to Hurricane Sandy. Address and location data for many facilities was missing, invalid, or in the wrong county. The EPA's Facility Registry Service helped fill some gaps by integrating data from other EPA programs and sources. The document calls for more reliable infrastructure data to better support emergency response, assessment of damage, and prioritization of aid.
