Four shipper groups have asked federal regulators to make public a key section of the Union Pacific-Norfolk Southern merger agreement, arguing that the railroads improperly shielded material that outlines when UP could walk away from the deal. The section, known as Schedule 5.8, was omitted from the railroads' initial merger application and later ordered to be filed, but the railroads labeled it 'highly confidential,' restricting access to outside attorneys and consultants.

Why it matters

The section of the merger agreement is important because it includes what regulatory conditions that UP will not accept should the STB approve the transcontinental merger. The shipper groups argue that the 'highly confidential' designation deprives interested parties of the railroads' own assessment of the conditions that might address the merger's harms.

The details

The four shipper groups that have asked the Surface Transportation Board to make Schedule 5.8 public are the Alliance for Chemical Distribution, the American Chemistry Council, the American Fuel & Petrochemical Manufacturers, and The Fertilizer Institute. These groups argue that Schedule 5.8 does not contain any sensitive commercial information, such as traffic data, shipper identities, rates, cost data, or trade secrets, and therefore should not be shielded from public view.

  • The railroads submitted their merger application on December 19.
  • The STB later ordered the railroads to file Schedule 5.8.
  • The shipper groups have now asked the STB to make Schedule 5.8 public.

What’s next

The Surface Transportation Board will need to decide whether to make Schedule 5.8 public or maintain its 'highly confidential' designation.

The takeaway

This dispute over the confidentiality of a key merger agreement document highlights the tension between the railroads' desire to protect sensitive information and the need for transparency and public participation in the regulatory review process.
