| File Note: |
It is submitted that the rice sheller was granted consent to operate under the Water (Prevention & Control of Pollution) Act, 1974 vide no. CTOW/Renewal/PTA/2018/8529999 dated 12/10/2018 having validity upto 30/09/2028 and under the Air (Prevention & Control of Pollution) Act, 1981 vide no. CTOA/Renewal/PTA/2018/8529946 dated 16/10/2018 having validity upto 30/09/2028 for paddy processing capacity of 3.0 TPH (without drier) and discharge of domestic effluent @ 0.7 KLD subject to suitable conditions.
Now, the industry has applied for obtaining consent to establish (NOC) modernization of its unit from pollution angle for installation of drier of capacity 24 T and manufacturing of rice @ 2.0 TPH by processing of paddy @ 3.0 TPH (With Drier) alongwith discharge of domestic effluent @ 1.5 KLD onto land for plantations under orange category along with requisite documents i.e. application form, CA certificate, feasibility report, Tehsildar report etc.
Project report:
As per the project report the cost of expansion is about Rs. 5 Lakhs, which is attributed to the cost of drier.
The manufacturing process involved is paddy pre-cleaning drying de-husking separation polishing packing & storage.
NOC fees: -
The industry has deposited Rs. 700/- vide no. 182253740 dated 17.04.2024 as NOC modernization fee, which is adequate for one year.
Tehsildar report:
The industry has submitted report issued by Tehsildar, Patiala dated 10.04.2024 in which it is mentioned as under:
Feasibility report:
The industry has submitted feasibility report prepared by Terrasyn Initiative, 587- Urban Estate, Phase-2, Patiala. The details regarding pollution sources in the unit and control systems proposed are as follows:
The industrial unit is planning to add a paddy pre-cleaner and a paddy drier along with a pre-cleaner to the existing set up.
The paddy pre-cleaner cleans the paddy of dust/dirt and other foreign matter before drying/milling. In the paddy drier process, rice husk will be fired in a fixed grate furnace. The hot flue gases (from combustion) will be passed vertically upward through a column. The paddy, to be dried, will be released in the column from the top. The counter-current arrangement of flue and paddy will make efficient use of drying system. In order to facilitate proper mixing of hot air with paddy, horizontal section of inclined trays are introduced. Multiple sections/zones of trays, spaced vertically, are provided. The drier furnace will consume about 50 kg/hour of rice husk/fuel wood.
As the expected dust loading in the combustion emission will be very less, the emission will not require any gas cleaning device.
Process emissions (paddy pre-cleaning/paddy transfer)
The air pollution is potentially due to dust getting released in paddy pre-cleaning process as well as during paddy transfer/release in the paddy drier (at inlet and outlet to the elevator feeding the paddy drier column).
The only type of pollution problem associated with the process is air pollution due to removal of foreign matter/dust present in the raw paddy during the pre-cleaning and transfer of paddy to the drier (lifting/release of paddy by the elevator downstream of the pre-cleaner).
As per the norms of Punjab Pollution Control Board (as applicable to the industry), the air emission shall not have SPM levels (in the stack) exceeding 750mg / Nm3.
The industry has proposed to install cyclone as air pollution control device followed by stack of height 3 meter above roof level to control process emissions to be generated from paddy pre processing and shall achieve emissions standards for SPM ≤750 mg/Nm3.
The industry was visited by the undersigned on 30.04.2024 and contacted Sh. Rajinder Kumar, Partner of the unit at site. During visit, it was observed as under:
i) The unit was not in operation due to off season.
ii) The unit is located outside MC limits of Patiala.
iii) The industry has installed drier and was in the process of installing cyclone and paddy pre-cleaner within the existing premises.
iv) The industry has installed two no. rula, three no. polishers, 1 no. whitener, etc.
v) The industry has installed cyclone as APCD to control the process emissions.
vi) The roads for the movement of the vehicles inside the sheller premises upto rice room, shelling shed and rice husk storage area, are brick paved roads.
vii) The industry provided proper rice husk storage facilities inside the factory premises and the height of brick wall in front of the discharge point of rice husk area is at least 3.5' higher than the discharge point of the rice husk pipe.
viii) The total height of the brick wall is about 15' approximately which seems to be adequate. The industries has provided layer of wind screen of 3' approx above the brick wall.
ix) The industry is not discharging any trade effluent, only domestic effluent is being generated and septic tank is provided for treatment.
It is pertinent to mention here that as per Govt. of Punjab, D.S.T.E 10/48/2004-STE (4) /932 dated. 15/10/2013, “All rice mills/ saila plant located outside the Municipal limits of towns and cities and in the designated areas within the cities established with NOC of Punjab Pollution Control Board will be allowed to expand/ modernize within their existing premises if pollution load of existing unit has been effectively taken care of by the industry and no specific approval of District Town Planner will be required.”
The site of the unit is located outside the master plan of Patiala. The site is suitable for expansion/modernization of the unit, as per the policy of the Board.
In view of the above mentioned facts and documents submitted by the industry, it is recommended that NOC for expansion/modernization from pollution angle for processing of paddy @ 3 TPH (with drier) to manufacture dry rice @ 2.0 TPH and to discharge domestic effluent @ 1.5 KLD onto land for plantation after septic tank may be granted to the industry with suitable conditions as per the policy of the Board and following additions conditions:-
1. The industry shall comply with the code of practice notified by Govt. Notification no. 10/48/2004-STE (4) /932 dated 15/10/2013 in true letter and spirit.
2. The industry shall not use any other fuel except rice husk in the furnace.
3. The industry shall obtain varied consent to operate under the provisions of Water (Prevention and Control of Pollution) Act, 1974 and the Air (Prevention and Control of Pollution) Act, 1981.
4. The industry will submit its building plan prepared and duly authenticated by the Director of Factories/ Chartered Architect/ Chartered Engineer under the provisions of section 3-A of Punjab Factory Rules, 1952.
5. The industry shall install APCD as proposed in the technical report submitted by the industry along with the application.
6. The industry shall not undertake washing of driers and generate trade effluent.
7. The industry shall comply with the guidelines for abstraction of ground water from Punjab Water Regulation and Development Authority (PWRDA).
8. The industry shall comply with the stack emissions standards as laid down by the Board and as amended from time to time by the Board/MoEF.
9. The industry shall not generate and discharge any trade effluent. It shall only generate and discharge domestic effluent onto land for plantation only after treatment in septic tank.
