These quotes are taken from environmental assesments from the government. Most things done are about birds, sewage, and marine life.
The government relocated flats of bird habitat to mitigate wildlife loss. “Approximately 185 acres of wilted-coral mudflats will be lost with the construction of the Reef Runway. These areas are used mainly by the following migratory birds: Golden Plover, Ruddy Turnstone, and Sanderling. The Hawaiian Stilt [...] <is> an endangered species that uses this area as a roosting ground. [...] The state of Hawaii will replace this loss of wildlife habitat.” As seen in another survey, the government made sure that the project would actually be useful for the effort put in as well as the ecological harm it could produce. “The Reef Runway will be built in two increments [...] Construction will consist of construction for the breakwater and placing the dredge material for the runway and part of the taxiways. It is expected that there will be localized pollution by fines in the area of construction, but this will be kept to a minimum by the use of a hydraulic suction dredge and impoundment of all fill areas. Any pollution caused by construction will be temporary, reversible and will cause no permanent damage to the remaining portion of Keehi Lagoon.” “Approximately 186 acres of silted-coral mudflats will be lost with the construction of the Reef Runway. This area is used mainly by the following migratory birds: Golden Plover, Ruddy Turnstone, and Sanderling.” ”At the end of FY 1973, the Reef Runway project was idle, but work was progressing satisfactorily under a $350,881 contract to relocate bird habitats the runway would displace.”.

The remaining sewage from the HIA (Honolulu Int. Airport) now being discharged through the sewer outfall at Ahua Point, will be rerouted to the City’s system in conjunction with the Reef Runway project.” Environmental groups worked to keep the government in check. They held a panel to accuse the government of noise issues. “environmental panel holds ‘educational session’”: several people brought up specific proposals such as the Honolulu reef runway” Many things changed after the runway was built. The runway allowed many more aircraft into the airport. some ecological areas improved after the project… The Citizens Against Noise group complained that noise wouldn’t go down further slowing down the project. “On the same side as Citizens Against Noise has been the State’s Office of Environmental Quality. [...] this transport mode could have devastating effects upon environmental quality and upon public health.” The government reported about Marine Life, Environmental Consultants, and the lagoon. “Marine Life. The nearshore marine communities in Mamala Bau. Ke’ehi Lagoon and Hickam Harbor have been subjected to various disturbances since the early 1900s [...] A single colony of coral was noted along the circulation channel B (dredged as part of the Reef Runway. [...] Inner Ke’ehi Lagoon probably was not adversely affected during construction of the Reef Runway.”
