The U.A.E. Commission on Energy Efficiency and Renewable Energy says that natural gas lines would have had an expense of more than $400 million, according to a draft analysis released by the commission on Wednesday.

The cost was the biggest of any type of gas line on the U to B pipeline system.

The costs included maintenance, transportation, and electricity costs for the pipeline.

“These costs are significant and represent an excess of $400.4 million over the estimated cost of a comparable natural gas pipeline,” said the draft analysis by the U of A’s Natural Gas Commission.

The U of a has asked the commission to revise the study.

The report also found that the U-to-B pipeline would have cost an additional $16.8 million per year in electricity and $3.1 million per day in maintenance.

The commission says the report does not include any cost-related changes to the pipeline that would have affected the overall cost of the project.

The pipeline would run from an existing natural gas well to a proposed new natural gas terminal in the central region of the state of Texas, according a draft environmental impact report obtained by the Texas Tribune.

The proposed natural gas facility would be built by an American company and would run for about 30 years.

The draft report did not say what changes to replace existing natural fuel infrastructure would have to be made.

A state official familiar with the commission’s deliberations told the Tribune that it has been working on the draft report for months and was preparing to present it to the commission in July.

The study does not address the possibility of using natural gas as a bridge fuel for electric power generation.

The state’s Energy and Natural Resources Department has asked utilities across the country to develop alternative ways to provide power to communities in need.

The agency has also asked utilities to consider alternatives to relying on coal for electricity.
