Challenge. Shortly after commissioning, CPV Towantic noticed its oil/water separator (OWS) effluent flowmeter was inaccurate, requiring the outlet valve to remain closed until the instrument could be repaired or replaced and certified. Primary concern was that the OWS is responsible for removing oil from the wastewater stream prior to its discharge (Fig 1). To keep […]
Challenge 1. While CPV Towantic was in the process of its Spill Prevention, Control, and Countermeasure (SPCC) recertification (from the pre-construction initial submission) and was seeking PE certification for the EPA submission, the certifying professional engineer expressed concern with the (1) so-called shed roof around the 1.5-million-gal diesel-oil tank’s secondary containment, and (2) lack of

Challenge. The annual cost of providing casualty and property insurance to protect facility owners from significant financial hardship in case of a loss event can reach into the millions of dollars. Annual insurance inspections help “rheostat” this cost in either direction. The more areas of concern the insurance engineers and the inspectors have, the more

Challenge. CPV Towantic is an outdoor facility. The OEM-provided generator collector-house assemblies allowed moisture to collect around brushes and rigging during heavy rain events (Fig 10). Generator field resistance to ground was alarming, and in one case tripped the generator. Initial thought was moisture was coming in around the brush inspection door. After much investigation
