# 1 SUBJ: Defrost Deicing and Feasibility of ADF Collection Technologies

FROM: Brian Damico

Commenters to the deicing proposal explained that an airport in the very southern portion of the United

States could have significant departures but use little ADF. In particular, commenters requested that EPA

consider a de minimis cut

‐ off to account for defrosting. Under the proposal, defrosting would have

been counted towards the volume of ADF required to be collected, yet commenters claim that ADF

defrosting applications evaporate and are unable to be collected. After considering these comments,

EPA agrees that defrost deicing would generate little to no available ADF making ADF collection

technologies infeasible. EPA excluded defrost deicing from the definition of available ADF.

However, while EPA collected ADF purchase data in the questionnaires, EPA did not collect information

on the portion of this ADF that is used for defrost deicing. In addition, commenters were not specific

enough (e.g. southern portion of U.S.) for EPA to determine specific geographic areas that only or

predominantly conduct defrost deicing. Nor did commenters suggest a way for EPA to determine which

airports predominantly conduct defrost deicing. Therefore, EPA looked to the data it collected in the

questionnaires to see if it could determine an ADF usage that may correspond with defrost deicing.

Table 1 shows, for each airport questionnaire respondent, the location of the airport, its three year

average of ADF purchase, its three year average of departures, and its reported ADF collection

technologies. EPA then ranked these from the lowest ADF usage to the highest ADF usage. As can be

seen in the table, the highest ADF at which an airport reported evaporation as a treatment technology is

approximately 30,000 units. Therefore, EPA determined that ADF usage above 30,000 units did not

correspond to predominantly defrost deicing.2Table1:ADFUsageandManagementbyAirportAirportIDAirportNameAirportStateAirportWeightingFactorADFUsage(normalizedgallons/yr)HDDCategoryFacilityReportedCollectionTechnology1038LuisMunozMarinIntlPR1N/A<3,0001039KahuluiHI1N/A<3,0001049LanaiHI9.232574976N/A<3,0001073HonoluluIntlHI1N/A<3,0001077KonaIntlatKeaholeHI3.844027556N/A<3,0001125Sarasota/BradentonIntlAirportFL5.184967746N/AA1083TampaIntlAirportFL1N/AANone1106FortLauderdale/HollywoodIntlAirportFL1N/AA1055MiamiIntlAirportFL1N/AA1042OrlandoIntlAirportFL1N/AA1081BobHopeAirportCA1N/ABAbsorbed
