The intent of the regulations is to ensure that <br />the systems, on a continuing basis, efficiently remove pollutants from stormwater runoff thereby preventing <br />pollution ofthe nation's water resources. These Specifications apply to the FloGard@ LoPro Matrix Filter. <br /> <br />RECOMMENDED FREQUENCY OF SERVICE: <br /> <br />Drainage Protection Systems (DPS) recommends that installed FloGard@ LoPro Matrix Filters be serviced on a <br />recurring basis. Ultimately, the frequency depends on the amount of runoff, pollutant loading and interference <br />from debris (leaves, vegetation, cans, paper, etc.); however, it is recommended that each installation be serviced <br />a minimum ofthree times per year, with a change of filter medium once per year. DPS technicians are available <br />to do an on-site evaluation, upon request. <br /> <br />RECOMMENDED TIMING OF SERVICE: <br /> <br />DPS guidelines for the timing of service are as follows: <br />1. For areas with a definite rainy season: Prior to, during and following the rainy season. <br />2. For areas subject to yeat'-round rainfall: On a recurring basis (at least three times per year). <br />3. For areas with winter snow and summer rain: Prior to and just after the snow season and during the <br />summer rain season. <br />4. For installed devices not subject to the elements (wash racks, parking garages, etc.): On a recurring <br />basis (no less than three times per year). <br /> <br />SERVICE PROCEDURES: <br /> <br />1. The catch basin grate(s) or cover shall be removed and set to one side. <br />2. The service shall commence with collection and removal of sediment and debris (litter, leaves, papers, <br />cans, etc.). <br />3. The catch basin shall be visually inspected for defects and possible illegal dumping. If illegal <br />dumping has occurred, the proper authorities and property owner representative shall be notified as <br />soon as practicable. <br />4. Using an industrial vacuum, the collected materials shall be removed from the filter liner and interior <br />of the catch basin. (Note: DPS uses a truck-mounted vacuum for servicing FloGard@ LoPro Matrix <br />Filters.) <br />5. When all of the collected materials have been removed, the filter assembly shall be removed from the <br />drainage inlet. The outer filter liner shall be removed from the filter assembly and filter medium <br />pouches shall be removed by unsnapping the tether from the stainless steel hooded outlet cover and set <br />to one side. The filter liner, PVC body and fittings shall be inspected for continued serviceability. <br />Minor damage or defects found shall be corrected on the spot and a notation made on the Maintenance <br />Record. <br />6. More extensive deficiencies that affect the efficiency of the filter (torn liner, etc.), if approved by the <br />customer representative, will be corrected and a quote submitted to the representative along with the <br />Maintenance Record. The filter liner and filter medium pouches shall be inspected for defects and <br />continued serviceability and replaced as necessary and the pouch tethers re-attached to the stainless <br />steel hooded outlet cover assembly. <br />7. The grate(s) or cover shall be replaced. <br /> <br />Exhibit C <br /> <br />Page 3 of8 <br />
