(D) One galley and one lavatory total coliform sample collected per aircraft. Assume 30% of aircraft will sample annually, 30% of aircraft will sample twice annually, 30% of aircraft will sample quarterly, and 10% of aircraft will sample monthly. Assumes no more than one TC+ sample per aircraft.
(E) Assume 3.6% of coliform samples will be TC+ based on AOC data. Assume each aircraft has no more than one positive sample.
(F) For aircraft with initial TC+ samples, assume 0% of aircraft performing annual routine monitoring, 0% of aircraft performing twice annual routine monitoring, 50% of aircraft performing quarterly routine monitoring, and 46% of aircraft performing monthly routine monitoring will perform repeat
sampling. Assume 5.7% of aircraft performing repeat sampling will have one additional TC+ sample (based on AOC data).
(G) For aircraft with initial TC+ routine sample, assume 0% of aircraft performing annual routine monitoring, 0% of aircraft performing twice annual monitoring, 50% of aircraft performing quarterly monitoring, and 46% of aircraft performing monthly monitoring will collect three repeat samples within
24 hours of notification of TC+ as an alternative to immediate corrective action. Assume aircraft with less than three sampling points collect a total of 300 mL of samples from all available sampling points.
(H) Additional routine coliform monitoring not specified, assumed no additional routine coliform samples collected.
(I) Assume 100% of aircraft performing annual and twice annual routine monitoring, 50% of aircraft performing quarterly monitoring, and 54% of aircraft performing monthly will collect two follow-up samples after undergoing corrective action disinfection and flushing.
(J) Assume 0.5 hour for sample collection and for processing, storage, and shipping of sample. (Sample set burden is 1 hour for (2) routine samples, 1.5 hours for (3) repeat samples, and 1 hour for (2) corrective action follow-up samples.)
(M) Assume all analysis conducted by outside lab.
(O) Estimated courier fees based on costs from various courier services in major cities. Assumed courier services required for each sample set. (Sample set consists of 2 routine samples, 3 repeat samples, or 2 corrective action follow-up samples.) Assumed airport distance of 20-30 miles from
lab. Assumed courier would return cooler to air carrier.
(Q) Average coliform analysis costs based on costs from various labs across the country (fall 2006 data, updated to 2008 dollars). Assume all analysis conducted by outside lab.

(V) Refrigerators are purchased by air carriers. Assume costs for 63 air carriers are distributed evenly across the 7,327 aircraft.
(W), (X), (Y) Based on EPA estimate. Maintaining the maintenance log consists of recording all samples taken.
(Y) Air carriers must report their water system inventory within 18 months of promulgation of the Final Rule and update that inventory annually. The initial submission of inventory information is assumed to be submitted with the sampling plan.
The burden in this column reflects only the annual inventory updates.
(Z) Assume burden for 63 air carriers is distributed evenly across the 7,327 aircraft.
(AA) Based on technical labor costs for inspectors, testers, sorters, samplers, and weighers, from Exhibit 5.

and 54% of aircraft performing monthly routine monitoring will perform corrective disinfection and flushing after a positive routine total coliform sample. Assume the remainder of aircraft with a TC+
sample will perform repeat sampling. Assume 5.7% of aircraft performing repeat sampling will have at least one additional TC+ sample and will perform corrective action. Additionally, of the aircraft
with routine TC+ samples, assume 0% of the 100% of aircraft monitoring annually, 0% of the 100% of aircraft monitoring twice annually, 0% of the 50% of aircraft monitoring quarterly, and 46% of
aircraft monitoring monthly will incur costs for corrective action disinfection and flushing. Remainder of aircraft performing corrective disinfection and flushing are assumed to coordinate corrective
action with routine disinfection and flushing schedule, and therefore do not incur separate costs for corrective disinfection and flushing. Assume entire aircraft is flushed if either lavatory or galley has
a positive total coliform sample. Assume no more than one TC+ per aircraft.
(E) Assumes first flushing/disinfecting is successful.
(F) EPA estimate based on observation of flushing and disinfection practices.
(G) Based on labor rates for cleaners of vehicles and equipment from Exhibit 5.
(H) Chemicals used for disinfection cost approximately $1 per application (based on 12.5% chlorine solution from Harcros Chemicals, which costs $12 per 4 gallon jugs).
(J) Based on EPA estimate. Includes recording disinfection activities in maintenance log.
(K), (M) Recordkeeping burden and costs based on total number of corrective action disinfection and flushing events plus repeat disinfection and flushing events. Total number of corrective action disinfection and flushing events is from Exhibit A.8, column I.

Sources:
(D) Air carrier labor rates from Exhibit 5. EPA used the transportation inspector category because it was the highest-paid technical labor category. Transportation
inspectors are assumed to have a technical background, as well as some management or oversight responsibility.

-

(E) Labor burden reflects EPA estimate for reporting and recordkeeping only. EPA assumes that air carriers already conduct major maintenance checks, which include
self-inspection components, every five years for each aircraft. Therefore, with the exception of reporting and recordkeeping burden, no additional costs for selfinspections are incurred by air carriers under the ADWR. Reporting requirements include certification that self-inspections have been completed, notification of any
deficiencies detected during self-inspections, along with corrective actions taken, and any other reporting and recordkeeping needed to prepare for compliance audits by
EPA.
(F), (G) All aircraft undergo compliance audits once in 5 years. The Agency will review electronic data for all aircraft at the airline office site. Assumes labor burden for
self-inspection reporting and recordkeeping is evenly distributed across the 63 airlines.

Notes:
(D) Derived from column I, Exhibit A.8, which calculates number of followup samples following corrective action. Each aircraft with a total coliform-positive sample takes two followup samples after completing corrective action.
(E) From column D, Exhibit A.11. Includes only those corrective actions that do not overlap with routine disinfection and flushing. Assumes a one-to-one correspondence between corrective action and aircraft.
(F) EPA assumption. Air carriers that choose to take longer than 72 hours to conduct corrective action must restrict public access and provide public notification.
(G) Assumes each aircraft has no more than one TC+ sample.
(H) From column D, Exhibit A.8.
(I) Percentage of routine samples positive for E. coli from AOC data. All air carriers with positive E. coli samples must restrict public access and provide public notification on the affected aircraft. Note that E. coli-positive repeat samples also trigger
the same requirements; however they occur so rarely that they do not significantly affect the number of PN events, so they were not included.
(J) Note that a sample can be positive for both total coliform and E. coli at the same time. By accounting for each type of sample separately, EPA may be overestimating the number of events requiring public notification. However, they must be
accounted for separately, because the public notification requirements vary for each.
(K) EPA estimate, based on burden for preparing a Tier 2 public notice in the Public Water System Supervision ICR. Includes time needed to prepare notice for crew, post placard for passengers (where required), and report to EPA.
(M) Loaded labor rate for transportation, storage, and distribution managers from Exhibit 5.
