Coastal Regulation Zone

Under the section 3 of Environment Protection Act, 1986 of India, Coastal Regulation Zone notification was issued in February 1991 for the first time, for regulation of activities in the coastal area by the Ministry of Environment and Forests (MoEF).

As per the notification, the coastal land up to 500m from the High Tide Line (HTL) and a stage of 100m along banks of creeks, lagoons, estuaries, backwater and rivers subject to tidal fluctuations, is called the Coastal Regulation Zone (CRZ). CRZ along the country has been placed in four categories. The above notification includes only the inter-tidal zone and land part of the coastal area and does not include the ocean part. The notification imposed restriction on the setting up and expansion of industries or processing plants etc. in the said CRZ. Coastal Regulation Zones (CRZ) are notified by the Government of India in 1991 for the first time. Under this coastal areas have been classified as CRZ-1, CRZ-2, CRZ-3, CRZ-4. And the same were retained for CRZ in 2003 notifications as well.

• CRZ-1: These are ecologically sensitive areas , these are essential in maintaining the ecosystem of the coast. They lie between low and high tide lines. Exploration of natural gas and extraction of salt are permitted
• CRZ-2: These areas are urban areas located in the coastal areas. Under Coastal Regulation Zone (CRZ) Notification 2018, the floor space index norms has been unfrozen.

• CRZ-3: Rural and urban localities which fall outside the 1 and 2. Only certain activities related to agriculture and even some public facilities are allowed in this zone
• CRZ-4: This lies in the aquatic area up to territorial limits. Fishing and allied activities are permitted in this zone. No Solid waste should be let off in this zone. This zone has been changed from 1991 notification, which covered coastal stretches in islands of Andaman & Nicobar and Lakshadweep.
