2 Introduction:

In Uttara Kannada district there are four major rivers namely Kali,

Gangavali, Aghunashini and Sharavathi, which are perennial in nature and are

flowing towards west and joining to Arabian Sea. Most part of the rivers covers

under Coastal Regulation Zones .The traditional community residing at river banks

are depends on fishing, sand collection, Lime shell collection etc. They have been

practicing removal of sand for their livelihood since many decades. These

traditional coastal communities use to remove the sand from sand bars which

come across as obstacles for navigation of boats of fishermen and public water

transportation by their traditional methods. They had been doing sand removing

and selling the sand in the local market after paying royalty as per state

Government rules periodically.

As per CRZ Notification 2011 river bed, river water, creek bed and creek

water were also included in CRZ area; sand removing is completely stopped since

sand mining is prohibited activity in the CRZ area. Therefore Ministry of

Environment and Forest, New Delhi considering state government request given

provisions to state Government to permit traditional communities for removal sand

bars manually in CRZ area in the Office Memorandum dated 8-11-2011.

Recently requisitions from the local communities from the river banks were also

received to remove sandbars for smooth navigation. District sand monitoring

(CRZ) committee, Uttara Kannada district had identified 21 sand bars with the

supervision of NITK, Suratkal and prepared the sand bar maps and the quantity of

removable sand from sand bar was also assessed.

2.1 Identification of project and project proponent:

As per Karnataka Minor Mineral Concession Rules 1994 amendment 2013

rule 31U (5) R/w

“Notwithstanding anything contained in these rules, nothing this chapter shall

apply for sand quarrying within the area of coastal regulation zone (CRZ) in

coastal district and shall be disposed of in accordance with the office memorandum

issued by Ministry Of Environment and forest, Government of India NO.11-

83/2005-IA-III (Vol-III): dated 8-11-2011 and as amended from time to time.

Provided further that the rule 8(1-A) shall apply mutatis muntandis for sand

quarrying in coastal regulation zone.”

District sand Monitoring Committee (CRZ), Uttara Kannada district headed by

Deputy Commissioner as a proponent hereby submitting for clearance from

Karnataka State Coastal Zone Management Authority (KSCZMA) and

Environment Clearance (EC) from State Environment Impact Assessment

Authority (SEIAA). Hence submitting this proposal for removal of sand from sand

bar no ‘’SB-GA-01” of Gangavali river in Ankola taluk in Uttara kannada district for Environment Clearance (EC) to member secretary SEIAA, Forest

Ecology and Environment Department, Multi Store building, Bangalore.

(A copy of the Office Memorandum No. dated 8-11-2011 is annexed as Annexure-

I)

2.2 Brief description of nature of the project :

The removal of sand from sand bar ‘’SB-GA-01” which inhibits smooth

navigation of fishing boats, which also fetches huge quantity of sand across the

district as construction material. The removal of sand could be done by traditional

communities manually and disposed off after recovering royalty to the state

government.

2.3 Need for the project and its importance to the country and or region.

This activity envisages local employment to the traditional communities as

well as worth gives ample opportunities to the lorry owners who transport sand to

the local people, (for construction of building, houses, bridges, roads etc.) of the

district. Many National and State projects such as NH widening, state highway,

Sea Bird projects and government construction work are completely depending on

the sand produced by this project.

5

2.4 Demand-Supply Gap.

Since the beginning of the civilization Gangavali river sand has being

utilized for construction of the houses. The prohibition on the sand mining in CRZ

area (as per CRZ notification-2011) creates acute shortage of sand in the district.

By this project we envisage to meet the local demand of the sand in the district.

2.5. Employment Generation (Direct and Indirect):

This project involves local traditional community in removing of sand

manually with local small boats and local equipments like bamboo, shovel, and

baskets etc. which provides ample employment to the local community. The local

people who are registered by the Committee (constituted as per OM dated- 8-11-

2011) will sell the sand in local market. And transportation of the sand by Lorry

owners where loading and unloading of sand will be done manually, requires

labors, drivers and cleaner etc.

The sand which used for construction of houses, buildings, and road and

bridges etc. all work are also labor oriented (skilled-unskilled). In between this

activity indirectly enhances hotel, restaurant Tea-shop, and puncher-shop

businesses which also require skilled-unskilled labors.

3. Project Description:

3.1 Type of project including interlinked and interdependent projects, if

any.

As many Government projects like- widening of National Highways, road,

bridge government building constructions work awarded in the district requires

river sand as raw material, all projects will be hampered due to non availability of

sand as long as this project get started.

3.2 Location :

Ankola town is located west coast part of Karnataka state, India and the

river Gangavli originates from Western Ghats in the district and runs for 183 km

and meets Arabian Sea in the heart of the town. The sand bar ‘’SB-GA-01”

The removed sand from sand bar may be stored at river bank at safer

distance by the registered traditional community. Then sand will be transported to

the destinations on demand of the consumers.

3.3 Details of alternate sites,

The sand accumulation is more at the site is due to formation of meander

which leads to check to the river flow which dumps heavy sediment (mostly sand

particles) at the site. As the river is perennial in nature at this region because of

power generation process will be continue throughout the year and the

replenishment of sediment (sand) occurs throughout the season. After removal of

sand from sand bar there will be chance of accumulation of sand at the same place

which flown from the upstream part of the river on regular basis.

4. Site Analysis:

4.1 Topography :

The sand bar is well located within the Gangavali river, the sand bar developed

at the meander. The accumulation of sand at the site may forms land if the removal

of sand is not done in course of time and which could be called “delta” at the river

mouth of Gangavali river.

District sand Monitoring Committee (CRZ), Uttara Kannada district headed by

Deputy Commissioner as a proponent had submitted a proposal for CRZ clearance to

Karnataka State Coastal Zone Management Authority (KSCZMA). And in pursuance

with rules the Chairman is hereby submitting the project “Removal of sand from Sand

Bar SB-GA-1 of Gangavali river in Ankola taluk of Uttara 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:

Uttara Kannada District is located N-W part of Karnataka state falls in between Latitude:

14° -15° N and longitude of 74°-75°. The District has four major estuaries viz. Kali, Gangavali,

Aghanashini, and Sharavathi. The Kali estuary is located in the northern most part of the

district, the Bedthi or Gangavali about 35 km south from Kali river-mouth, the Aghanashini or

Tadri estuary, about 12 km south of Gangavali, and the Sharavathi estuary is about 28 km south

of the Aghanashini estuarine mouth.

The sand bar “SB-GA-1” is located in Gangavali river bed of Ankola taluk.

Gangavalli River is one of the many small rivers that originates and flows entirely within the

western part of state of Karnataka in India. Gangavalli River (also called Bedthi River) originates

from the Western Ghats at two places; one is near Someswara temple, south of Dharwad and

another is near Hubli, both join near Kalghatgi, Dharwad district. The total length of the river is

around 183 km, This river has a catchment area of 3,574 km2 and it has no dam or hydel power

station. It joins the Arabian Sea at Gangavali near Ankola taluk.

B. 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 Gangavali river courses and identified sand

bar “SB-GA-1”. While identification of sand bar ecologically sensitive area and fish breeding

areas (CRZ-I) 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 NITK

Surathkal in its report has made the point that it’s better to take 0.6 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:

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. The removal of sand is completely manual by human efforts by hands and collected in baskets or by bamboos scoping and collected inside the mesh. Then loaded in the nadadoni. The collected sand will be stocked at river bank owned by traditional communities /port land (dakke). The removal of sand will be continuing till the completion of specified quantity which enables the smooth navigation at the demarcated place. During removal of sand following condition will be followed by the registered traditional communities:

1. Sand should not be removed depth beyond average bed level.

2. If bank or bed erosion takes place sand should not be removed.

3. Sand removal from the river bed other than the identified sand bar is prohibited.

4. Sand should not be removed near any vegetation or Mangroves growth.

5. Use of any mechanical methods for removal of sand is strictly prohibited.

6. If any damages to ecological system and the environment are observed, removal of sand

should be stopped.

7. Only day time (6am to 6pm) sand may be removed.

8. No instruments/materials should be left behind in the river course.

9. Minimum distance of 2 meter should be maintained from river bank for stocking of

sand.

10. In order to safe guard the river banks and roads sand removing/transportation along

the river banks should be prohibited in monsoon season i.e. June 15 to August-30.

Sand is the one of the essential commodity comes under non specified minor mineral categorytermed as " Ordinary Sand " in schedule-2 of Karnataka minor mineral concession rules 1994 towhich Government of Karnataka has fixed Rs. 60/- per metric ton. In Uttara Kannada district forconstruction of houses, other building, bridges and roads people of the district and neighboringdistricts are depends on these river (Kali, Gangavali, Aghunashini and sharavathi )sand onlysince many decades. Hence District sand Monitoring (cRZ) committee has decided to disposethe sand through registered traditional community people by collecting Royalty and otherstatutory taxes through Dept of Mines and Geology. sand will be transported by using validmineral dispatch permits (MDP) in order to regulate illegal sand transportation/mining activityin CRZ and non CRZ areas from the respective rivers.
