DTE Energy Company
Part 5 Compliance at DTE Service Centers

DTE Energy Company retained NTH to evaluate existing oil and chemical storage at 17 DTE service centers. They operate as a pull out facility for DTE line trucks. The service centers store and distribute electrical equipment and materials used by the line crews. Transformers and portable substations are staged on site and DTE utility vehicles are stored, fueled and maintained at the Service Centers.

Project Approach
The scope of services was to evaluate storage areas as to their compliance with the
Federal SPCC regulations and Michigan Act 451 Part 5 Rules. NTH provided a variety
of engineering solutions for each site and created design drawings for the chosen
solution.

Each service center has differing needs for oil and chemical storage, so prior to visiting the sites, existing site maps were acquired. On site, the various storage areas were reviewed and possible containment solutions were discussed with available site
personnel. This was an iterative process, as more internal DTE personnel got
involved and provided operational constraints to the possible solutions to secondary
containment issues on their sites.

The number of storage areas per site ranged from five to ten. Solutions for
containment included simple spill pallets or decks, pre-engineered lean-tos, curbing
and even the design and construction of a storm water detention pond.

NTH provided various spreadsheets to assist the DTE project managers in tracking the specific service center areas, alternative solutions, the chosen alternatives, other
decisions by site personnel, the design and construction progress, and estimated
costs for each storage area.
