Types of maintenance that the Vendor is required to perform. 1. Proactive maintenance, which is the daily monitoring, of CNG station systems including critical flow, temperature, pressure, vibrations, fugitive leaks, and false alarms. Electronic monitoring is an acceptable alternative to on-site inspection. This is necessary to minimize emergency shutdowns, which are unacceptable if more than 2 times per month unless caused by TPS personnel negligence or abuse. 2. Scheduled maintenance is specific maintenance performed in conformance with manufacturer’s recommendations and industry best practices. Vendor shall develop a scheduled maintenance process per each manufacturer or vendor’s requirements and perform all this maintenance on a timely basis. This is necessary to eliminate emergency shutdowns and catastrophic failures. 3. Emergency maintenance is unplanned service resulting from a system shutdown or failure causing the CNG station to not be operational. Contractor shall provide TPS a report of the emergency covering the resources required to fix the problem, the length of time the CNG station or compressor was shutdown, the cause, steps taken to fix the problem, and steps taken to prevent it from happening again. The Contractor shall locally store and maintain an adequate supply of critical spare parts, based on manufacturers’ recommendations, for use in an emergency and the list must be approved by TPS.
