The petitioners are aggrieved by the order dated 14.12.2008 passed bys the SDM Bazpur and the order dated 20.4.2009 passed by the Uttarakhand Environment Conservation and Pollution Control Board, Uttarakhand, whereby the plant or the industrial unit of the petitioners has been stopped from functioning, as it does not have an environment clearance.

2. The case of the petitioners is that they have opened a “natural screening plant” in Village Bannakhera, Tehsil Bazpur, District Udham Singh Nagar. According to the petitioners as per the Environment (Protection) Act, 1986 and the rules framed thereunder, there is no provision for the petitioners to get a No Objection Certificate from the Environmental Protection Board, which is presently functioning in Uttarakhand, as there is no provision for taking such a certificate for a “natural screening plant” as it is not mentioned in the Schedule, to the Environment Protection Rules.

3. Admittedly, by a notification of the State of U.P. dated 3rd November, 2000 (contained as Annexure No. 4-A to the affidavit filed by respondent no. 4). The entire State of U.P. has been declared Air Pollution Control Area under Section 19(1) of the Air Pollution (Prevention and Control) Act, 1981 (From hereinafter referred to as the Act) and therefore, the net effect of the notification would be that the prior approval of the Board would be necessary before opening any plant or industry which is described in the Schedule given in Environment (Protection) Rules, 1986, which have been framed under the Act. What has to be seen is whether the plaint or the industry of the petitioners is such as to necessarily require a clearance from the Pollution Control Board. This can only be verified after examining whether such an industry is notified in the Schedule or not. In case it is notified a clearance would be mandatory, otherwise not. What has, however, be seen is the broad nature of the industry and not the precise nomenclature, stated in the schedule.

4. According to the petitioners, in the schedule to the Environment (Protection) Rules, 1986 (from hereinafter referred to as the Rules), there is no mention of “natural screening plant”, but what is does mention is a “stone crushing unit”. According to the petitioners, “natural screening plant” is not a “stone crushing unit” and therefore a No Objection Certificate is not required. This argument of the petitioners is not entirely satisfactory. The requirement of a “No Objection Certificate” is that before it is given the concerned factory adopts certain measures including preventive measure in the factory premises in order to reduce or minimize the air and water pollution. In order to mitigate some hazards, certain preventive measures have been given in the Schedule I of the Rules and only if the unit adopts these preventive measures, the No Objection Certificate or clearance can be granted. However, the petitioner reiterates that the schedule does not mention “the natural screening plant”. The fact of the matter is that the plant of the petitioners is a “natural screening plant”, which carries out the process of screening, separating and grading of river bed material into sand, gravel, pebbles and stones of various sizes. The entire process of separation results in stone particles being suspended in the air, which causes pollution. It is for this reason that a unit such a “stone crushing unit”, which by and large does a similar work and finds mention at Serial No. 11 in Schedule (I) of the Environment (Protection) Rules, 1986, there is a requirement for mitigating or checking the pollution so caused to the air. What is of significance is the removal of suspended dust particles from the air so that the pollution may be minimized. Undoubtedly, in a process presently undertaken by the petitioners, there is a pollution of the air and therefore, it is necessary that the petitioners must adopt the preventive measures such as (i) Dust Containment cum suppressi
