| RISK MATRIX AUDIT OF THE WATER POLLUTION CONTROL PLANT - PHASE I | C-1 Influent flow is measured after the bar screens and grit basins process. Magnetic meters only measure liquidity, therefore, influent equals effluent. | C-2 Influent flow is measured by two new magnetic meters. | C-3 The Regional Board has reviewed the calculations the Plant staff perform to arrive at effluent. | C-4 Various meters track usage of effluent on in-house processes. | C-5 Influent less the meters tracking in-house usage and effluent diverted to the SBWR project is the effleunt number that is reported to the Board. | C-6 Dye tests determine the accuracy of the meter being tested and a certificate is issued stating the test conclusion. | C-7 Plant staff informed the Regional Board of how effluent is calculated. | C-8 Plant staff monitor flow trends which are generated by the computer system that monitors the entire Plant. | C-9 Magnetic meters are re-calibrated based on a preventative maintenance schedule. | C-10 Portable meters can be utilized if meters in place are not working properly. | C-11 An inspector from the Regional Board conducts a surprise inspection annually. | C-12 Samples are taken for process controls. | C-13 Samples are taken in accordance with permit requirements. | C-14 Installation of new effluent meters in 5/99 with flow measurement requirements of +/- 2%. | C-15 Dye tests to be performed quarterly to verify +/- 2% accuracy of new effluent flow meters. | C-16 Potential effluent mag meter installation if new meters prove ineffective/inaccurate. (> +/- 2%) | C-17 Lab Quality Assurance procedures which will be tested later. | C-18 WPCP staff calculate loadings to determine if loadings are within limits. | C-19 New mag meter located at SBWR pump station. | C-20 Meters located at each industry site. | C-21 Monthly industry reporting requirements with justification for changes in flow/toxin levels. | C-22 Flow regulators on-site at industries to manage inflows to Plant for flow limitations. | C-23 All financial incentive programs require proof of installation and results prior to payment. | C-24 Diversion construction projects that costs exceed $50K require Council approval. | C-25 Routine inspections of manholes and pipelines to determine if repairs are needed. | C-26 Bids are required for sewer pipe repairs. Public Works oversees these projects. | C-27 Technical Advisory Committee reviews all Fund 512 and 513 costs for appropriateness. | C-28 Conservation programs are required to meet a minimum flow reduction of 1 mgd to obtain Council approval. | C-29 ULFT diversion program participants must meet program criteria and be approved by relative water retailer. | C-30 ULFT program participants' approval is not transferrable and is substantiated by pre-printed coupons and approved vouchers. |
