2 OPERATION & MAINTENANCE Maintenance Summary o Clean filter as needed based on local loading conditions. o Evaluate and replace hydrocarbon media booms (BioSorb) as needed. Notes: o Loading varies at every location due to variations in pollutant and flow volumes. o Maintenance typically occurs before and after the rainy season. o Media booms and replacement parts can be provided by Bio Clean Environmental Services, Inc. Operation A. Maintenance can be provided by the Supplier, or a Supplier approved contractor. The cost of this service varies among providers. B. The Bio Clean Grate Inlet Skimmer Box (GISB) is a multi-stage catch basin filter. These stages include: absorption of hydrocarbons and multi-level screening. It is recommended that the system be inspected every 6 months to evaluate its condition. The first year of inspection and maintenance can be used to predict maintenance requirements for subsequent years. 1. Absorption - is provided by sorbent media booms. This boom is positioned in a tray around the top perimeter of the filtration basket. This booms targets hydrocarbons including diesel, gasoline and oil. This booms utilizes a poly known as BioSorb which permanently absorbs and retains captured hydrocarbons. It is recommended the media boom is replaced when its visual appearance is black in color. This procedure can be performed by hand. This procedure takes approximately 3-6 minutes depending on size of the filter. 2. Multi-Level Screening - is provided by a series of filtration screens. The surface area of the screens varies depending on the model number. The lower level contains the finest screens and as you move up the sides of the filter the screens

3 become larger. This ensures the filter can capture both fine and coarser sediments and associated pollutants while maintaining maximum flow rate capacity. These screens target trash, TSS, debris, and particulate metals and nutrients. It is recommended that the filter screens cleaned and captured debris removed one the filter is 50% full. Removal of captured debris and cleaning of the screens can be done by hand with with a vacuum truck. This procedure takes approximately minutes depending on the size of the filter. The Bio Clean Grate Inlet Skimmer Box is designed to allow for the use of vacuum removal of captured materials in the sediment chamber. The chamber is serviceable by centrifugal compressor vacuum units without causing damage to the filter or during normal cleaning and maintenance. Filters can be cleaned and vacuumed without entering the catch basin from finish surface. Filter does not need to be removed to replace media or clean. Maintenance Procedures: 1. Bio Clean Environmental Services, Inc. recommends the filter and media boom be inspected annually and cleaned when needed depending on loading. The procedure is easily done with the use of any standard vacuum truck. o Remove grate to gain access to the fitler. o Remove skimmer tray containing media booms and replace if needed by cutting zip ties, removing old boom, replace with new boom, zip tie into place. o Use a vacuum truck hose and insert into the catch basin. Lower the vacuum hose into the bottom of the filter. Begin vacuuming out accumulated sediments until the filter is empty. A pressure washer may be needed to assist with removing sediments that are compacted or stuck to the walls, screens and floor of the filter. o Once the filterr is cleaned remove vacuum hose. o Remove vacuum hose and replace grate cover. o Where possible the maintenance should be performed from the ground surface.

4 o o Note: entry into an underground stormwater catch basin requires certification of confined space training. Transport all debris, trash, organics and sediments to approved facility for disposal in accordance with local and state requirements. 2. Following maintenance and/or inspection, the maintenance operator shall prepare a maintenance/inspection record. The record shall include any maintenance activities performed, amount and description of debris collected, and condition of the system and its various filter mechanism. 3. The owner shall retain the maintenance/inspection record for a minimum of five years from the date of maintenance. These records shall be made available to the governing municipality for inspection upon request at any time. 4. Transport all debris, trash, organics and sediments to approved facility for disposal in accordance with local and state requirements.

5 Maintenance Sequence 1 2 Remove grates from catch basins to gain access to the GISB filters. Special hooks are available from various manufactures which are designed to remove the grates. 3 4 Remove skimmer tray and attached media booms. Remove old media boom by cutting zip ties. Replace with new media boom and fasten with zip ties. 5 6 Vacuum out accumulated trash, sediment, and debris OR clean by hand. A pressure washer or metal brush can be used to clean of the screens. Replace grates. Make sure they are properly re-installed.
