Does the permitting process consider limiting how long such a well can be used?

Yes. The permitting process considers a wide variety of factors regarding injection well operations and site suitability which includes a determination of how long a well can be used and how much liquid can be disposed in a well. These limitations are determined based on the capacity of the disposal reservoir and the expected operational lifetime of the well components. Fortunately, these issues are also monitored on a daily, monthly and annual basis. If well monitoring shows any problems with system performance, the well must be shut down and repaired or permanently abandoned to make certain that waste stays in the injection zone according to the permitted well design. Clauses describing this monitoring, repair or abandonment, and the financial assurance to follow the specified procedures, are required as permit conditions before injection operations can begin.
