In the United States, for example, a governmentally sponsored "Rigs-to-Reefs" program was organized (Reggio, 1989). Also proposed is the utilization of solidified ash wastes from oil and coal-burning electrical-generating stations. , Chang, 1985). Tracemetal leaching is one environmental aspect of oil ash reefs studied by Metz and Trefry (1988), who also identified the latest initiative for solid-waste disposal, namely municipal incinerator ash. Considerable care is essential to determine precisely the environmental and socio-economic costs, benefits, advantages, and constraints for each new material proposed as an artificial habitat.

The Japanese Fishery Agency's authority is so pervasive that it influences all aspects of artificial reef planning, construction, and technology development. Government subsidies are limited to those projects (studies and construction) that use government-certified reef products. Since reef construction without government subsidy is economically impractical, subsidies allow the government to effectively control the quality of reefs including building materials, design, location, and construction.
