CPCB (Central Pollution Control Board)

Air Pollution Emission Standards

Environmental standards approved by the peer and core committee of central board:-

The environmental standards for the cashew seed industry was discussed in 21^st peer and core committee and following are approved

Roasting Process, Cooking process and Borma operation

Parameter

Roasting

Process

Stack

(2-4 hours of operation)

Cooking Process

(4-6 hours of operation)

Roasted Shell **

Cooking Process

(4-6 hours of operation)

Deoiled Cake

Borma Oven Heater (4-6 hours of operation)

Roasted Shell **

Borma Oven Heater (4-6 hours of operation)

Deoiled Cake

Particulate matter

* 150 mg/Nm3

at 4% CO2

150** mg/Nm3

at 4% CO2

150mg/Nm3

at 4% CO2

150** mg/Nm3

at 4% CO2

150 mg/Nm3

at 4% CO2

Minimum Stack Height, m

20m from ground level

15 m from ground level or 2m above the height of the nearest building, whichever is higher

* The dog-house emissions are also to be directed together with the roasting drum emissions to wet scrubber to meet toe emission standard.

* * The unites have to install bio-gassifier to meet the emission standard specially wherever roasted shell is used for firing. Alternatively the deoiled cake may be used.

The Emission Standard for Plaster of Paris Industry as agreed by the Committee is as below:

An agenda on Emission Standard for Plaster of Paris Industry was placed in the 21^st meeting of the Peer & Core Expert Committee. The Committee suggests to constitute a Sub-committee to review the standards (1000 mg/Nm³at crusher and 2500 mg/Nm³at calciner furnace) was considered as lenient. Accordingly, a Sub-committee was constituted under the Chairmanship of Prof. J. M. Dave. Two meetings of the Sub-committee were held.

The agenda was presented by the Deputy Director National Productivity Council, Delhi, to the Committee including recommendations of the Sub-committee.

The need to elaborate the development of green belt in terms of distance from source, height, nature of plantations etc., was expressed in the meeting.

It was also felt that the options for utilization of solid waste should be explored instead of disposing in low-lying areas.

Some members expressed that emission standard pf 500 mg/Nm3is lenient. However, considering the fact that at present small units are operating without any pollution control equipment and also due to inadequate resources for implementation of stricter norms, the Committee agreed with the proposed standard of 500 mg/Nm3

S. No	Source	Emission Standard for Particulate matter (mg/Nm3)	Load/Mass based Standard (kg/tonne of finished product)	Minimum Stack Height
A.	Small Scale unit (up to 30 TPD)
1.	Raw material crushing	< 500	<1.5	10m from ground level or 3 m from top of the building whichever is higher
2.	Calciner Furnace	< 500	< 1.5
3.	Product Grinding	< 150	<1.0
B.	Large Scale Unites (more than 30 TPD)
1.	At all unit operations and processes	< 150	< 0.5	30 m from ground level or based on modeling in consulattion with local PCB so that excessive concentration (*) of pollutant will not result

(*) Excessive concentration is defined as one that causes exceedence greater than ambient air quality standard of the respective zone (industrial, commercial, residential and silence zones)

Guidelines : Fugitive Emission Control:

The particulate matter should not exceed 2000 ug/m3 at a distance of 3-10 from major dust generating sources.

Emission Standards for Electric Arc & Induction Furnaces

Agenda was placed in the 21^st meeting of the Peer & Core Committee for approval of proposed standard. The Committee suggested to constitute a Sub-committee to review the standard. A Sub-committee was constituted under the Chairmanship of Prof. J.M. Dave. Two meetings of the Sub-committee were held.

The agenda item was presented by Punjab State Council for Science and Technology, Chandigarh including recommendation of the Sub-committee in 23^rd meeting of the Peer & Core Committee. After detailed deliberations, the committee approved the standard as below

S.No.

TEXTILES

In Tirupur there are different plants.

Under this scheme, 50 % of the installation cost is born by the central government and the state government.

-----------------------------------------------------------------------------------------------------------

In textile industry, many industries have gone for treatment of waste water and the treated waste water is reused in the process. In many industries, there is virtually no waste water. This means they have overcome the water pollution problem.

-----------------------------------------------------------------------------------------------------------

In December 2008, a programme by the name of Treatment and Reuse of Textile Industry Effluents.

In this programme, CPCB will organize training program through IIT Delhi. The basic objective of the training program is to create awareness among the officials of State Pollution Control Boards, Pollution Control Committees and textile Industry. Number of participants will be about 25 and the duration will be 3 days. Venue will be IIT Delhi.

----------------------------------------------------------------------------------------------------------

Slaughter House – similar training program is to be organized at Bangalore through environment management policy and research institute 25 people.
