 Can you believe it when I say our entire coastliners divided into different zones? You have to believe it because it is the truth. Yes, I'm talking about the coastal regulation zone notification, which is released by the Ministry of Environment. And here is everything you need to know about the CRSIT notification. See in the year 1991, the Union Ministry of Environment notified the Coastal Regulation Zone notification. So, what does the notification do? See it declares certain coastal stretches as Coastal Regulation Zone under Section 3 of Environment Protection Act 1986. So, this is about the Coastal Regulation Zone notification. See, largely the CRSIT area is based on the high tide line. High tide line means the line on the land up to which the highest water line reaches during the spring tide. See, this HDL, which is the short form of high tide line, is demarcated by the National Centre for Sustainable Coast Management. Now, look at this image here. Here, the red line is high tide line and the blue line is low tide line. So, the low tide line is nothing but the lowest level up to which the water reaches during the spring tide. Now, with this basics, let us see about the different zone nations in CRSIT. First of all, we are going to see CRSIT 1. It includes areas between low tide line and high tide line. And it also includes areas that are ecologically sensitive and important such as national parks, marine parks, sanctuaries, reserve forests, wildlife habitats, mangroves, coral reefs, etc. And it also includes area which are closer to breeding and spawning grounds of fish. And it also includes areas of historical importance. See, all these areas, they come under CRSIT 1. And these areas are the most protected area. In this zone, no new construction will be permitted except for the projects relating to the Department of Atomic Energy and construction of trans-harbour sea link and routes. So, this is the exception. Now, apart from this, you should know that if an area that comes under CRSIT 1 is not a eco-sensitive zone, then the exploration and extraction of natural gas, salt harvesting and desalination plans are also allowed. So, this is also an exception. But the condition is the area under CRSIT 1 should not be a eco-sensitive zone. And only then these activities are allowed. Now, moving on to the next zone which is CRSIT 2. Now, look at this image here. Here, CRSIT 2 is highlighted in the orange colour. This includes area, landward of high tide line which includes the areas that are already developed. See, the crucial point here is it includes areas that are landward of high tide line. So, it extends from the sea towards the land. See here, developed area is referred to as that area within the municipal limits or in other legally designated urban areas which is already substantially built up. See, what does this mean? This means that these developed areas, they have already been provided with drainage, approach roads and other infrastructural facilities such as water supply, sewerage, etc. See, here no new construction shall be made on the seaward side. See, we saw that the area under CRSIT 2 extends from high tide line towards the land. So, what activity is prohibited here? New construction is not allowed on the seaward side which is towards the sea. And then reconstruction of authorised building will be permitted only if it adheres to the FSI norms. Here, FSI is nothing but floor space index. Now, that is all about the CRSIT 2. Now, coming to CRSIT 3, see, this includes areas that are relatively undisturbed and those which do not belong to either category 1 or category 2. See, in this image, CRSIT 3 is highlighted in red colour here. Now, as you can see, it is subdivided into two areas. The first area is 200m landward of the high tide line and it is called as the No Development Zone. See, here no construction shall be permitted except for the construction of gardens, pastures, parks, play fields, forestry and salt manufacture from seawater. Now, coming to the second subdivision, it is the area between 200m and 500m landward. See, here development of vacant plots for construction is allowed only after prior approval of states. Now, this is about CRSIT 3. Now, coming to the final one which is CRSIT 4. See, this includes areas 12 nautical miles seaward from the low tide line. See, CRSIT 4 is nothing but the territorial waters of the country. See, in this area, traditional fishing is allowed, but discharge of untreated sea wages prohibited. Now, these are the different zones that are categorised under the CRSIT notification. Now, finally, coming to who has the authority to give clearance. According to 2019 CRSIT notification, the Ministry of Environment, Forest and Climate Change will oversee the matter of CRSIT clearance only for CRSIT 1 and CRSIT 4. Do you remember what areas come under CRSIT 1 and CRSIT 4? Yeah, CRSIT 1 includes ecologically vulnerable areas and CRSIT 4 includes area between low tide line and 12 nautical miles seaward. So, for these two categories, Ministry of Environment gives the clearance. And the areas which comes under the other two categories that is CRSIT 3 and CRSIT 2, the power of clearance has been designated at the state level. That is, the authority to give clearance has been delegated to the states. And now, I hope you are very clear about the different zones in the CRSIT notification and you will be able to tell who has the authority to give the CRSIT clearance.
