And in pursuance with rules and Chairman is hereby submitting the project “Removal of sand from sand bar SB-G4 of Gurupura river in Mangalore Taluk in “Dakshina Kannada district” for Environment Clearance (EC) to Member Secretary, SEIAA, Forest Ecology and Environment Department, Multi Store building, Bangalore. A. Location of the sand bar: Dakshina Kannada District is located N-W part of Karnataka State falls in between Latitude: N-12° 56’00.00”and longitude of E 740 49’ 50.09” The District has two major estuaries viz. Nethravathi and Gurupura, The gurupura estuary is located in between the district, or south from Nethravathi river-mouth. The sand bar “SB-G4” is located in Gurupura river bed of Mangalore taluk. The Gurupura River has its origin near the village of Mangalore taluk in the Western Ghats and flows eastwards and joint the Arabian Sea near the town of Mangalore. this river has a catchment area of 3160 Sq.Km the river flows entirely through the district of Dakshina Kannada. The river is the lifeline to some 10 lakh people in the Dakshina Kannada district and supports the livelihoods of tens of thousand of people including fishermen on the coast of Dakshina Kannada. There are many dams built across this river for the generation of electricity. One of the important dams build across Nethravathi river is the Thumbe dam at Thumbe. The river runs 184 kilometers before joining Arabian Sea. The GPS location and Chakkubandi details are follows: Sand Latitude and Sand bar boundary Chakkubandi Distance from bar longitude of A,B,C,D, Latitude sea shore in KM No. sand bar points Longitude SB-G4 N-12° 56’00.00” N 12˚ 55' 52.36" North- part of sy no.171 6.50km towards A E-74° 49’50.09” E 74˚ 49' 44.38" South – part of sy no.171 east from N 12˚ 56' 13.65" East - part of sy no.171 Shoreline.

Removable sand Assessment: A team of officers consisting of Dept. of Mines and Geology, Revenue Dept, PWD Dept. KSPCB and CRZ officials had joint inspections of the sand bars using CRZ maps along with the traditional community people by traversing in the Gurupura river courses and identified sand bar “SB-G4”. While identification of sand bar ecologically sensitive area and fish breeding areas (CRZ-1) were excluded. Identified area has been marked in maps. Assessment of removable sand was made by considering 0.5 meter thickness of the sand bar, but Prof. S G Mayya, the Chairman Civil Engineer Dept. NITK Surathkal in his report has made the point that it’s better to take 1.4 meter depth for removal purposed as the rivers getting replenishment on all the days of the year and it is assessed accordingly. The sand bar assessment details is as follows: Sand bar Length of Width of Area in Area in Column Approximate No. the sand the sand Acres Hectare depth of removable bar in bar in (AC) (Ha) sand bar Quantity of meter meter in meter sand in MT (SG=1.5 MT) SB-G4 700 115 19.77 8 0.7 84,000 C. Methodology of Removal of sand: Non-mechanized dinghies or small boats are being used for removal of sand by traditional coastal community without using any machinery by using bamboo poles, baskets / buckets by human beings.

During removal of sand following condition will be followed by the registered traditional communities: 1. No sand should be removed wherever, bank or bed erosion is observed. 2. Sand removal activity to a distance of a minimum of 50 mtr, is not permitted around islands, mangroves, kudrus and also from both the river banks. 3. No mechanized method should be followed. 4.

If vented dams/ barrages are observed sand should not be removed to a distance of 15 mtr from both u/s and d/s cut off or solid apron. 8. Sand should not be removed at any place beyond the average river bed level. 9. No damages should be caused to environment, to the river banks and the ecological system. If any damage is observed sand removal should be stopped. 10.Sand should be removed only if the sand bars are observed at the identified locations. D. Disposal of sand: Sand is the one of the essential commodity comes under non specified minor mineral category termed as “Ordinary sand” in schedule-2 of Karnataka minor mineral concession rules 1994 to which Government of Karnataka has fixed Rs.60/- per metric ton.
