An entity may complete responses for each individual vehicle and include the vehicle's body type, weight class bin, and fuel type. If applicable, an entity must separately report vehicles dispatched under their brokerage authority. When responding, each vehicle must only be counted once for each response. An entity must report:
(i) Number of vehicles in each vehicle group;
(ii) Model year of the vehicle and engine for each reported vehicle;
(iii) The percent of the vehicles in each vehicle group with operating characteristics including, but not limited to: Daily mileage, usage patterns, refueling, trailer towing, and other such characteristics as specified by ecology. The term "usage pattern" shall include:

(d) An entity must choose a period of time, for example annual or quarterly data averaged for work days during the period selected to determine responses. For example, if an entity selects annual data to determine vehicle daily mileage, the entity must average the annual mileage accrued based on the number of work days that year.
(i) A shorter analysis period may be used if the reporting entity deems it more representative of periods of high vehicle utilization when answering questions about typical daily operation. For example, if a reporting entity with seasonal workload fluctuations determines that a week or month during the busy season is representative, average the data records for that week or month when determining a response.
(ii) If an alternative analysis period is used, the reporting entity must be prepared to describe their reasoning at the request of ecology.
(e) For information reported for a vehicle group at one location, a reporting entity may repeat that information for the same vehicle group at another vehicle home base if the reporting entity determines that the operation at the second location is substantially similar to that at the first location.
(f) A broker must provide information about vehicle usage that is dispatched under contract, such as if a broker hires a truck to move a load, only the miles driven under that contract are required for the response. If known, the broker may voluntarily report information about the miles driven outside the contract.
(4) Fleet reporting recordkeeping.
(a) An entity required to report must maintain all of the following records related to the reporting for five years after the reporting deadline:
(i) For owned on-road vehicles, mileage records and dates from records, such as maintenance logs, vehicle logs, or odometer readings, or other records with the information that the reporting entity used to prepare the information the entity submitted;
