The intent of Ihe regulations is to ensure that the systems, on a continuing basis, efficienlly remove pollutants from stonnwater runoff thereby preventing pollution of the nation's water resources. These specifications apply to the FloGard+Plus" Catch Basin Insert Filter. RECOMMENDED }'REQUENCY OF SERVICE: . Drainage Protection Systems (DPS) recommends that installed Flo-Gard+Plus" Catch Basin Insert Filters be serviced on a recurring basis. Ultimately, the frequency depends on the amount of runoff, pollutant loading and interference from debris (leaves, vegetation, cans, paper, etc.); however, it is recommended that each installation be serviced a minimum of three times per year. with a change of filter medium once per year. DPS technicians are available to do an on. site evaluation. upon request. RECOMMENDED TIMING OF SERVICE: DPS guidelines for the timing of scrvice are as follows: I. For areas with a definite rainy season: Prior to, during and following the rainy season. 2. For areas subject to year-round rainfall: On a recurring basis (at least three times per year). 3. For areas with winter snow and summer rain: Prior to and just afler the snow season and during the summer rain season. 4. For installed devices not subject to the elements (washracks, parking garages, etc.): On a recurring basis (no less than three times per years). SERVICE PROCEDURES: L The catch basin grate shall be removed and set to one side. The catch basin shall be visually inspected for defects and possible illegal dumping. If illegal dumping has occurred, the proper authorities and property owner representative shall be n!'tified as soon as practicable. 2. Using an industrial vacuum, the collected materials shall be removed from the liner. (Note: DPS uses a truck-mounted vacuum for servicing Flo-Gard+PluslZl catch basin inserts~) 3. When all of the collected materials have been removed, the filter medium pouches shall be removed by unsnapping the tether from the D-ring and set to one side. The filter liner, gaskets, stainless steel frame and mounting brackets, etc. shall be inspected for continued serviceability. Minor damage or defects found shall be corrected on-the-spot and a notation made on the Maintenance Record. More extensive deficiencies that affect the efficiency of the filter (tom liner, etc.), if approved by the customer representative, will be corrected and an invoice submitted to the representative along with the Maintenance Record. 4. The filter medium pouches shall be inspected for defects and continued serviceability and replaced as necessary and the pouch tethers re-attached to the liner's D-ring. See below. 5. The grate shall be replaced. Date Receiveci: _ ,{ Ct I (f\ Planner. tb ~ ~fY\t0~ Pla4u ~Ob~ REPLACEMENT AND DISPOSAL OF EXPOSED FILTER MEDIUM AND COLLECTED DEBRIS The frequency of filter medium pouch exchange will be in accordance with the existing DPS-Customer Maintenance Contract. DPS recommends that the medium be changed at least once per year. During the ""I"VI" ;ate service, or if so determined by the service technician during a non-scheduled service, the filter medium pouches will be replaced with new pouches. Once the exposed pouches and debris have been removed, DPS has possession and must dispose of it in accordance with local, state and federal agency requirements. Note: As the generator, the landowner is ul1imately responsible for the proper disposal of the exposed filter mediwn aruJ debris. Because rhe filrer media likely conUlin petrolewn hydrocarbons, heavy merals aruJ other hannful pollutnnts, the materials 11UlS/ be treated as an EPA Oass 2 H=nJous Waste aruJ properly disposed of. DPS relieves the landowner of the actual disposal task, aruJ provides ce11ffication of its completion ill accordance with appropriate regulations. DPS also has the capability of servicing all manner of catch basin inserts and catch basins without inserts, und..... __nd oil/water separators, stonnwater interceptors and other such devices. All DPS personnel are highly qualified technicians and are confined space trained and certified. Call us at (888) 950-8826 for further infonnation and assistance.
