The Coastal Regulation Zone (CRZ) consists of coastal land up to 500 meters from the High Tide Line (HTL) and 100 meters along banks of creeks, estuaries, backwaters, and rivers subject to tidal fluctuations. As a part of the Environment Protection Act of 1986, the Ministry of Environment and Forests was ordered to regulate coastal activities from 1991. Currently, the Coastal Regulation Zone around India has been divided into four categories, which ultimately help impose restrictions on industry expansion, activity, and processing.
