NOW, THEREFORE, it is agreed by and between the parties as follows: 1. OWNER RESPONSIBILITIES. The City shall provide, or has provided, Owner with an Operations and Maintenance Plan (each, an "O&M Plan") for each Facility. Owner agrees to operate, inspect and maintain each Facility in accordance with the current O&M Plan and any subsequent modifications to the O&M Plan. Owner inspections performed pursuant to the O&M Plan shall be referred to hereinafter as an"Owner Inspection". Owner shall maintain a log on inspection activities. The log shall be available to the City upon request during City inspections of the Facilities (each, a"City Inspection"). 2. DEFICIENCIES. All aspects in which the Facilities fail to satisfy the O&M Plan shall be noted as "Deficiencies". 3. CITY INSPECTIONS. Owner grants City the right to conduct City Inspections. City shall give ten (10) days prior written notice to Owner before conducting a City Inspection, except that no notice shall be required in case of an Emergency (defined below). City shall determine whether Deficiencies need to be corrected. Owner (at the address provided at the end of this Agreement, or such other address as Owner may designate in writing to City) shall be notified by City in writing (each, a "Deficiency Notice") through the US Mail of the Deficiencies within fifteen (15) days after the date of the applicable City Inspection. 4. OWNER CORRECTIONS. All Deficiencies shall be corrected at Owner's expense within thirty (30) days after (as applicable): (i) Owner's completion of the Owner Inspection or (ii) Owner's receipt of a Deficiency Notice. If more than 30 days is reasonably needed to correct a Deficiency, Owner shall have a reasonable period to correct the Deficiency so long as the correction is commenced within the 30-day period and is diligently prosecuted to completion. 5. CITY CORRECTIONS. If correction of all Owner or City identified Deficiencies is not completed within the timeframe set forth in Section 4, City shall have the right to have any Deficiencies corrected. City(i) shall have access to the Facilities for the purpose of correcting such Deficiencies and (ii) shall bill Owner for all costs reasonably incurred by City for work performed to correct the Deficiencies (the "City Correction Costs") following Owner's failure to correct any Deficiencies in the Facilities. Owner shall pay City the City Correction Costs within thirty (30) days of the date of Owner's receipt the applicable invoice from City (accompanied by reasonable documentation of such costs). Owner understands that this is a debt owing to City. In addition,Owner agrees that upon nonpayment, City Correction Costs shall be secured by a lien on the Property for the City Correction Cost amount plus interest. City shall use its best efforts to minimize interference with the operation of the Property when performing any inspections and/or corrections of the Facilities. 6. EMERGENCY MEASURES. If at any time City reasonably determines that the Facilities create any imminent threat to public health, safety or welfare (an "Emergency"), City may immediately and without prior notice to Owner take measures reasonably designed to remedy the Emergency. City shall provide notice of the threat and the measures taken to Owner as soon as reasonably practicable, and if such Emergency arose from a Deficiency with the Facilities, charge Owner for the cost of these corrective measures as provided in Section 5. 7. NOTICES. Any notice to a party required or called for in this Agreement shall be in writing and served to the address set forth below (i) in person, (ii) by deposit in the U.S. Mail, first class postage prepaid, or (iii) by an overnight courier service that confirms delivery.

It is a good practice to inspect the system after major storm events. Maintenance Frequency The primary factor for determining frequency of maintenance for Maintenance Procedures the StormFilter is sediment loading. Although there are many effective maintenance options,we A properly functioning system will remove solids from water by believe the following procedure to be efficient,using common trapping particulates in the porous structure of the filter media equipment and existing maintenance protocols.The following two-step procedure is recommended:: inside the cartridges.The flow through the system will naturally decrease as more and more particulates are trapped.

It is recommended that the site owner develop a database to properly manage StormFilter inspection and maintenance programs.. 2 Maintenance Decision Tree The need for maintenance is typically based on results of the inspection. The following Maintenance Decision Tree should be used as a general guide.(Other factors,such as Regulatory Requirements,may need to be considered) 1. Sediment loading on the vault floor. a. If>4"of accumulated sediment, maintenance is required. 2. Sediment loading on top of the cartridge. a. If>1/4"of accumulation, maintenance is required. 3. Submerged cartridges. a. If>4"of static water above cartridge bottom for more than 24 hours after end of rain event, maintenance is required. (Catch basins have standing water in the cartridge bay.) Inspection Procedures 4. Plugged media. The primary goal of an inspection is to assess the condition of a.

Warning: In the case of a spill,the worker should abort a_ If hazardous material release(automotive fluids or other) inspection activities until the proper guidance is obtained, is reported, maintenance is required. Notify the local hazard control agency and Contech Engineered Solutions immediately. 7. Pronounced scum line. a. If pronounced scum line(say>_ 1/4"thick)is present To conduct an inspection: above top cap, maintenance is required. Important Inspection should be performed by a person who is familiar with the operation and configuration of the Storm Filter treatment unit. 1. If applicable,set up safety equipment to protect and notify surrounding vehicle and pedestrian traffic. 2. Visually inspect the external condition of the unit and take notes concerning defects/problems. 3. Open the access portals to the vault and allow the system vent. 4. Without entering the vault,visually inspect the inside of the unit, and note accumulations of liquids and solids. 5. Be sure to record the level of sediment build-up on the floor of the vault, in the forebay,and on top of the cartridges. If flow is occurring, note the flow of water per drainage pipe. Record all observations. Digital pictures are valuable for historical documentation. 6. Close and fasten the access portals. 7. Remove safety equipment. 8. If appropriate, make notes about the local drainage area relative to ongoing construction, erosion problems, or high loading of other materials to the system. 9. Discuss conditions that suggest maintenance and make decision as to whether or not maintenance is needed. 3 Maintenance Depending on the configuration of the particular system, maintenance personnel will be required to enter the vault to perform the maintenance. Important: If vault entry is required, OSHA rules for confined space entry must be followed. Filter cartridge replacement should occur during dry weather. It may be necessary to plug the filter inlet pipe if base flows is occurring. Replacement cartridges can be delivered to the site or customers facility. Information concerning how to obtain the replacement cartridges is available from Contech Engineered Solutions. Warning: In the case of a spill,the maintenance personnel should abort maintenance activities until the proper guidance is obtained. Notify the local hazard control agency and Contech Engineered Solutions immediately. To conduct cartridge replacement and sediment removal maintenance: 1. If applicable,set up safety equipment to protect maintenance personnel and pedestrians from site hazards. 2. Visually inspect the external condition of the unit and take notes concerning defects/problems. 3. Open the doors(access portals)to the vault and allow the system to vent. 4.

Related Maintenance Activities - Performed on an as-needed basis StormFilter units are often just one of many structures in a more comprehensive stormwater drainage and treatment system. In order for maintenance of the StormFilter to be successful, it is imperative that all other components be properly maintained. The maintenance/repair of upstream facilities should be carried out prior to StormFilter maintenance activities. In addition to considering upstream facilities, it is also important to correct any problems identified in the drainage area. Drainage area concerns may include:erosion problems, heavy oil loading, and discharges of inappropriate materials. 5 Inspection Report Date: Personnel: Location: System Size: System Type: Vault Cast-In-Place Linear Catch Basin Manhole _ Other Date: Sediment Thickness in Forebay: Sediment Depth on Vault Floor: Structural Damage: Estimated Flow from Drainage Pipes(if available): Cartridges Submerged: Yes ❑ No _ Depth of Standing Water: StormFilter Maintenance Activities(check off if done and give description) ❑ Trash and Debris Removal: L Minor Structural Repairs: I Drainage Area Report Excessive Oil Loading: Yes No Source: Sediment Accumulation on Pavement: Yes I No ❑ Source: Erosion of Landscaped Areas: Yes No ❑ Source: Items Needing Further Work: Owners should contact the local public works department and inquire about how the department disposes of their street waste residuals.
