(d) Index D. Three vehicles - 
(1) One vehicle carrying the extinguishing agents as specified in paragraphs (a)(1) or (a)(2) of this section;
and
(2) Two vehicles carrying an amount
of water and the commensurate quantity of AFFF so the total quantity of
water for foam production carried by
all three vehicles is at least 4,000 gallons.
(e) Index E. Three vehicles - 
(1) One vehicle carrying the extinguishing agents as specified in paragraphs (a)(1) or (a)(2) of this section;
and
(2) Two vehicles carrying an amount
of water and the commensurate quantity of AFFF so the total quantity of
water for foam production carried by
all three vehicles is at least 6,000 gallons.
(f) Foam discharge capacity. Each aircraft rescue and firefighting vehicle
used to comply with Index B, C, D, or
E requirements with a capacity of at
least 500 gallons of water for foam production must be equipped with a turret. Vehicle turret discharge capacity
must be as follows:
(1) Each vehicle with a minimumrated vehicle water tank capacity of at
least 500 gallons, but less than 2,000
gallons, must have a turret discharge
rate of at least 500 gallons per minute,
but not more than 1,000 gallons per
minute.
(2) Each vehicle with a minimumrated vehicle water tank capacity of at
least 2,000 gallons must have a turret
discharge rate of at least 600 gallons
per minute, but not more than 1,200
gallons per minute.
(g) Agent discharge capacity. Each aircraft rescue and firefighting vehicle
that is required to carry dry chemical,
halon 1211, or clean agent for compliance with the Index requirements of
this section must meet one of the following minimum discharge rates for
the equipment installed:
(1) Dry chemical, halon 1211, or clean
agent through a hand line - 5 pounds
per second.
(2) Dry chemical, halon 1211, or clean
agent through a turret - 16 pounds per
second.
(h) Extinguishing agent substitutions.
Other extinguishing agent substi-

tutions authorized by the Administrator may be made in amounts that
provide equivalent firefighting capability.
(i) AFFF quantity requirements. In addition to the quantity of water required, each vehicle required to carry
AFFF must carry AFFF in an appropriate amount to mix with twice the
water required to be carried by the vehicle.
(j) Methods and procedures. FAA Advisory Circulars contain methods and
procedures for ARFF equipment and
extinguishing agents that are acceptable to the Administrator.
(k) Implementation. Each holder of a
Class II, III, or IV Airport Operating
Certificate must implement the requirements of this section no later
than 36 consecutive calendar months
after June 9, 2004.

Section 139.319 Aircraft rescue and firefighting: Operational requirements.
(a) Rescue and firefighting capability.
Except as provided in paragraph (c) of
this section, each certificate holder
must provide on the airport, during air
carrier operations at the airport, at
least the rescue and firefighting capability specified for the Index required
by Section 139.317 in a manner authorized by
the Administrator.
(b) Increase in Index. Except as provided in paragraph (c) of this section, if
an increase in the average daily departures or the length of air carrier aircraft results in an increase in the Index
required by paragraph (a) of this section, the certificate holder must comply with the increased requirements.
(c) Reduction in rescue and firefighting.
During air carrier operations with only
aircraft shorter than the Index aircraft
group required by paragraph (a) of this
section, the certificate holder may reduce the rescue and firefighting to a
lower level corresponding to the Index
group of the longest air carrier aircraft
being operated.
(d) Procedures for reduction in capability. Any reduction in the rescue and
firefighting capability from the Index
required by paragraph (a) of this section, in accordance with paragraph (c)
