Okla. Stat. tit. 17, § 17-159.17: Provisions of certificate - Defaults

Each certificate of convenience and necessity issued by the

Commission shall establish time limits within which construction

must be started but in no case shall this exceed six (6) calendar

months. The certificate shall also establish a time limit within

which the certificated water transportation line will be made

available for public service. The certificate shall also provide

for reports to the Commission at appropriate intervals indicating

the progress of construction, the percentage of completion of the

major phases of the project, changes in the estimated completion

dates, and any other appropriate information which may be required

by the Commission.

If the Commission shall determine that the certificate holder

appears to be in default as to the time limits set out in the

certificate, it shall conduct a hearing, after ten (10) days'

notice, and require the certificate holder to show cause why the

certificate should not be canceled. If the certificate holder shall

show that it is in default for good cause, such as unanticipated

engineering difficulty, national emergency making materials

unavailable for construction, or other valid reasons over which the

certificate holder has no control, the Commission may extend the

time set out in the certificate or in any previous extension. In

the absence of good cause shown, the certificate shall be canceled.

The Commission shall conduct a hearing to extend such time

limits upon application of the certificate holder, and may make

extension for good cause shown.
