Tennessee Statutes require that utilities have their projects reviewed by the Municipal Planning Commission of the City the project is located in. The utility may overrule the decision of the Municipal Planning Commission, BUT it must submit the plans for review.
This seems to make common sense. The City has the right to review and comment on a project, but the utility (MLGW in this case) has the right to complete the project for the benefit of the customers.
The Tennessee Statutes appear to be clear in this. MLGW obviously disagrees, but in spite of many promises from MLGW legal staff to send us "proof" that they don't need to even have their projects reviewed, we have not received any such "proof" from the MLGW legal staff, so we assume the position of the City is correct.
For obvious reasons, any City should have the right to review projects in its' City limits and Tennessee Statues support this right.
