<br />? The sam lin ro ram will consist of <br />P S p g on-site hydrogen sulfide measurements, air flow (velocity) <br />? measurements, and laboratory analysis of reduced sulfur compounds of the inlet air. This will be <br />done for each of the two scrubber systems. <br />Task 2. Review design and operations data <br />All design information including drawings and specifications will be reviewed to thoroughly <br />understand the design intent. Information on chemical consumption, operating parameters, <br />monitoring data, and maintenance requirements will be reviewed and evaluated to determine if <br />existing chemical consumption and maintenance requirements are consistent with wet scrubbers <br />of these types and inlet air characteristics. Any performance test data or reports will also be <br />reviewed. Use of the data collected in Task 1 and a knowledge of the system design will allow <br />development of a"preliminary load balance" for each odor group. <br />Task 3. Evaluate options to upgrade odor control svstems <br />We will evaluate all feasible options for upgrading the scrubbers to ensure they reliably and <br />consistently perform at optimum levels. For example, merely upgrading the chemical metering <br />and control system may provide reliable operation, but if high levels of reduced sulfur <br />compounds are detected it may be necessary to change the scrubber chemistry to optimize <br />removal of these difficult-to-treat compounds. New control technology has also become <br />commercially available in the past few years that can better control chemical feed rates to match <br />demands. <br />Task 4. Prepare report of recommendations <br />A draft report will be prepared for review by the City of North Olmsted that includes detailed <br />recommendations for upgrading the existing odor control systems. Preliminary design and <br />performance criteria will be developed along with sketches of any required modifications. If <br />monitoring equipment can be purchased "off the shelf ' directly by the City of North Olmsted, <br />recommendations will be developed for specific equipment. Cost estimates will be developed <br />01,
