About this file
This document is Exhibit G of the BARC EPSS (Generator/ATS/MTS) Maintenance and Repair IDIQ contract, containing the NFPA 110 Emergency Power Supply System (EPSS) Maintenance Log template for the Beltsville Agricultural Research Center (BARC), USDA-ARS in Beltsville, Maryland.
The maintenance log template is based on NFPA 110-2022 Figure A.8.3.1(b) and provides a standardized framework for tracking preventive and corrective maintenance activities on emergency power generation systems. The log accommodates two maintenance levels (Level 1 and Level 2) and uses frequency abbreviations: W (Weekly), M (Monthly), Q (Quarterly), S (Semi-Annual), and A (Annually), with some items indexed to operating hours (3/500 hours, 5/500 hours). The template requires documentation of generator model, engine model, installation date, standby kW nameplate rating, 30% of standby rating, fuel type, and normal operating temperature. Maintenance components tracked across multiple sections include: Fuel System (supply tank, day tank, pumps, filters, hoses, piping, and wiring); Lubrication System (oil level, changes, filters, and breather); Cooling System (coolant, antifreeze, water flow, radiator, belts, and ductwork); Exhaust System (leakage, condensate, insulation, and supports); Battery System (electrolyte, terminals, specific gravity, and charger); Electrical System (connections, safeties, circuit breakers, and transfer switch); Prime Mover/Engine (air cleaner, governor, ignition, injectors, and load testing); Generator End (brushes, commutator, rotor, stator, bearings, and voltage regulator); General Condition (unusual noises, vibrations, leakage, and service area); and Automatic Transfer Switch (general inspection, exercising under load, controls, contacts, and thermographic scanning). The log provides columns for recording readings and dates for each maintenance activity across multiple inspection periods.
