DTE Energy Company Part 5 Compliance at DTE Service Centers
DTE Energy Company retained NTH Consultants, Ltd. to evaluate existing oil and chemical storage at seventeen 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.
