Effective Date Note:
At 77 FR 34146, June 8, 2012, § 86.1803-1 was amended by adding definitions for “Ambulance”, “Diesel exhaust fluid”, “Emergency vehicle”, and “Fire truck”, and revising the definition for“Defeat device”, effective August 7, 2012. For the convenience of the user, the revised text is set forth as follows:
§ 86.1803-01 Definitions.
Ambulance means a vehicle used for emergency medical care that provides all of the following:
(1) A driver's compartment.
(2) A patient compartment to accommodate an emergency medical services provider and one patient located on the primary cot so positioned that the primary patient can be given intensive life-support during transit.
(3) Equipment and supplies for emergency care at the scene as well as during transport.
(4) Safety, comfort, and avoidance of aggravation of the patient's injury or illness.
(5) Two-way radio communication.
(6) Audible and visual traffic warning devices.
Defeat device means an auxiliary emission control device (AECD) that reduces the effectiveness of the emission control system under conditions which may reasonably be expected to be encountered in normal vehicle operation and use, unless:
(1) Such conditions are substantially included in the Federal emission test procedure;
(2) The need for the AECD is justified in terms of protecting the vehicle against damage or accident;
(3) The AECD does not go beyond the requirements of engine starting; or
(4) The AECD applies only for emergency vehicles and the need is justified in terms of preventing the vehicle from losing speed, torque, or power due to abnormal conditions of the emission control system, or in terms of preventing such abnormal conditions from occurring, during operation related to emergency response. Examples of such abnormal conditions may include excessive exhaust backpressure from an overloaded particulate trap, and running out of diesel exhaust fluid for engines that rely on urea-based selective catalytic reduction.
Diesel exhaust fluid (DEF) means a liquid compound used in conjunction with selective catalytic reduction to reduce NOX emissions. Diesel exhaust fluid is generally understood to conform to the specifications of ISO 22241.
Emergency vehicle means a vehicle that is an ambulance or a fire truck.
Fire truck means a vehicle designed to be used under emergency conditions to transport personnel and equipment and to support the suppression of fires and mitigation of other hazardous situations.
