Requires the Secretary to develop model laws (including regulations) for the mapping and survey of underwater pipelines and encourage States to adopt them. Requires States as a condition to receiving Federal grants for pipeline safety programs to have such laws in effect and enforce them.

Requires the Secretary to promulgate regulations relating to the safe operation of underwater pipelines and pipeline facilities operating in sensitive aquatic environments. Requires the Secretary to promulgate regulations requiring all underwater pipelines to accommodate instrumented internal inspection devices (smart pigs).

Requires the Administrator of the Environmental Protection Agency to study the effects of hydrostatic testing of pipeline facilities.
