6. If the employee is involved in an accident at work and the person
providing treatment administers a blood test for drugs and alcohol, Big
River may rely on and take disciplinary action based on the results of the
blood test, provided that the company did not request or suggest the blood
test be administered.

D. Regular Testing: Regular testing may be scheduled for all employees on a
calendar or project assignment basis to meet project, contract, or other
requirements. Testing will occur during, immediately before, or immediately after
a regular work period.

E. Random Drug Testing. A neutral and objective selection process will be adhered
to by an independent entity. Each employee has an equal chance of selection for
initial testing and the selection process is computer generated.

F. Reasonable Suspicion Testing. Big River may require an employee to submit to a
drug and/or alcohol test based on the reasonable suspicion that the employee is
using or has used drugs or alcohol in violation of this policy. The company or a
designee will evaluate the evidence to determine if reasonable suspicion exists.
Reasonable suspicion shall be based on specific objective and articulable facts and
reasonable inferences drawn from those facts, including, but not limited to, any of
the following:

(a) Observable phenomena, such as direct observation of alcohol or drug
use or physical symptoms of drug or alcohol use.

(b) Abnormal conduct or erratic behavior or a significant deterioration in
work performance.

(c) A report of drug or alcohol use from a credible source.

(d) Evidence that the employee has tampered with any drug or alcohol
test.

(e) Evidence that the employee has manufactured, sold, distributed,
solicited, possessed, used, or transferred drugs while working, at
work, or using a vehicle or machinery owned by Big River.

G. Post-Accident Testing. An employee who is involved in an accident that results
in substantive property damage or reportable personal injury may be required to
participate in a drug and alcohol test. Such an accident constitutes reasonable
suspicion.
