OF RANCHO CUCAMONGA, CALIFORNIA FOR THE SUPPLY OF CONTINUOUS EMISSIONS MONITORING SYSTEM GASES AT RIVERSIDE'S POWER PLANTS FOR A PERIOD OF SIX YEARS IN THE AMOUNT OF $826,860 ISSUE: Consider awarding Request for Bid No. 8027 to Airgas, Inc. of Rancho Cucamonga, California for the supply of continuous emissions monitoring system gases at Riverside's power plants for a period of six years in the amount of $826,860. RECOMMENDATION: That the Board of Public Utilities award Request for Bid No. 8027 to Airgas, Inc. of Rancho Cucamonga, California for the supply of continuous emissions monitoring system gases at Riverside's power plants for a period of six years in the amount of $826,860. BACKGROUND: The Continuous Emissions Monitoring Systems (CEMS) are critical air emissions monitoring equipment systems at each of Riverside's electric power generation plants — Riverside Energy Resource Center (RERC), Springs and Clearwater. Environmental regulations require CEMS to be installed and to provide continuous, uninterrupted monitoring on a "24/7" basis. The CEMS consists of several analyzers that sample and measure extremely low concentration levels (less than 2.5 parts per million) of air emissions discharged from each individual generating unit, for a total of nine (9) units. The United States Environmental Protection Agency (EPA) and the South Coast Air Quality Management District (SCAQMD) require properly functioning CEMS to measure and monitor compliance with Riverside's air quality operating permits. Maintaining LEMS operation for each generating unit involves EPA certified specialty gases to perform daily calibrations and quarterly certification tests on over 40 emissions analyzers. An essential element of this process requires a supplier to provide cylinders of calibration gases and exchange them when they are empty. Also, the supplier must manage the EPA certification of some calibration gases which can take up to 8 weeks to obtain.
