oann�OLUE <br />ENVIRONMENTAL SERVICES, INC. <br />925 West Esther St. <br />Long Beach, CA 90813 <br />Ph: (562) 624-4120 <br />Fx: (562) 624-4127 <br />Bypass Jetting: Using our utility truck & specialized Jetter Vactor, we jet 27 bypasses and 180 culverts for debris <br />(i.e. dirt & gravel). In order to effectively complete this scope of work, safety & traffic control are essential. Many <br />times, bypass cleaning requires lane/shoulder closures using reflective cones & arrow boards. Confined space <br />entry protocol is also sometimes used. <br />During inspections we found an inlet fully <br />impacted with concrete. We later mitigated <br />the problem area by performing confined <br />space entry and using heavy equipment <br />Hydrodynamic Separators: Ocean Blue currently holds Stormwater maintenance contracts for various Southern <br />California Cities. We currently maintain over 50 hydrodynamic separators, each of which are cleaned 3 times a <br />year. During inspections we open manholes to observe any floatables. Using a stadia rod we measure quantities <br />of s e di m e n t 1 oc at e d at t he b o t t om of t he Hydr odynami <br />inspections & cleanings together (rather than on separate occasions). All reports are thoroughly completed <br />indicating any damages and screen conditions. We also report conditions of the inlet/outlet sumps. <br />Contech Filter Media cleaning and BMPs: Ocean Blue maintains <br />Contech-filter-vault-cleaning contracts all across southern California. <br />Varying in size, these vaults are pressure washed once a year (or sooner <br />should an illicit discharge occur). We are also familiar with bioretention <br />units, bioswales, drywells and other underground infiltration systems. <br />Stormwater lift stations: We have extensive experience in providing lift <br />station on -call services for the County and neighboring cities (vacuuming <br />& monitoring). Specifically for Santa Ana, Ocean Blue will work closely <br />with Amaz Engineering —the current lift station maintenance provider — <br />to meet City needs (electrical & mechanical repair). <br />Installation of Gates and BMPs: Ocean Blue can install custom gates & <br />trash excluder devices like automatic retractable screen covers, connector <br />pipe screens, and/or flex storm drain filter inserts. Based on screen length <br />& height, bypass height, we will custom fabricate screens for best fit. All <br />devices are County approved. In addition, we can perform any city - <br />mandated stenciling while retrofitting catch basins. <br />LONG BEACH . <br />Page 28 of 29 <br />SAN DIEGO <br />
