NNS I ) <br /> used to calculate Event Mean Concentrations (EMC) for specific land uses which have been used to <br /> demonstrate compliance with Total Maximum Daily Load(TMDL) requirements. <br /> ENVIRONMENTAL PROTECTION AGENCY(EPA) CONSENT DECREE COMPLIANCE <br /> SERVICES <br /> We have extensive experience in EPA Consent Decree compliance,having developed and managed HDOT's <br /> SSWMP in response to HDOT's EPA Consent Decree.We also have extensive experience in working with the <br /> State of Hawaii, Department of Health, Clean Water Branch's engineering and enforcement sections with <br /> regards to the NPDES and 401 WQC requirements. Similarly,we have worked with the Department of Health, <br /> Solid Waste Program's personnel on permitting and compliance issues. Examples of our capabilities in this <br /> area include the SSWMP and EPA Public Outreach and Training Program(Both with HDOT). These projects <br /> involve the coordination of numerous professionals with expertise spanning a broad range of disciplines. <br /> CIVIL ENGINEERING <br /> Our civil engineers have a broad range of design experience on federal-aid and non-federal-aid projects and <br /> have the skills and knowledge to take a project from preliminary design through final design, and including <br /> construction management. Constructibility,with special consideration for maintenance of traffic, property <br /> adjustments, utility relocations, environmental protection, and other constraints, is our specialty in the <br /> preparation of construction plans and specifications.The NELHA Airport Connector Roads and Other Roads <br /> on Host Park and Farrington Highway Improvements at Nanakuli Avenue and Haleakala Avenue are examples <br /> of our capabilities in this area. Our civil engineering staff is experienced in the latest State and Federal <br /> standards and requirements, and is capable of providing the following services: <br /> — Conceptual Design Studies <br /> — Program Management <br /> — Project Management <br /> — PS&E Preparation <br /> — Construction Management <br /> HYDROLOGY AND HYDRAULICS DESIGN <br /> We have extensive experience in hydrology and hydraulics. Our projects have advanced the state-of-the-art <br /> and have won numerous awards for engineering technology, and have designed open channels and closed <br /> conduit, storm drain systems, catch basins, energy dissipater structures, inlets, and outlets. <br /> Examples of our drainage designs and stream improvements in Hawaii include Waimanalo Flood Control and <br /> Drainage, Interstate Route H-3, Moanalua Road, and Keehi Interchange.For the Hawaii Water Systems <br /> Technical Studies Program Statewide Dam Break Analyses State of Hawaii for the USACE/Department of Land <br /> and Natural Resources (DLNR), our team was tasked with performing field investigations, hydrologic and <br /> hydraulic modeling of various dam break scenarios, and flood inundation mapping for the Puu Lua Reservoir <br /> on the island of Kauai and the Kualapuu Reservoir on the island of Molokai. In addition,we provided services <br /> on the Central Oahu Watershed Study,Phase 2 for the USACE/City and County Department of Environmental <br /> Services. On that project,the team was tasked with selecting an appropriate watershed model and then <br /> applying that model to the Waikele watershed. <br />
