/531In exercise of the powers conferred by sections 6, 8 and 25 of the Environment (Protection) Act, 1986 (29 of 1986), the Central Government hereby makes the following rules, namely:-1. Short title and commencement .-(1) These rules may be called The Manufacture, Storage and Import of Hazardous Chemicals Rules, 1989.
2. Definitions .-In these rules, unless the context otherwise requires,-
3. [ Duties of authorities
.-The concerned authority shall,-4. General responsibility of the occupier during industrial activity .-(1) These rules shall apply to,-
(a)an industrial activity in which a hazardous chemical, which satisfies any of the criteria laid down in Part I of Schedule I [or listed] in column 2 of Part II of this Schedule is or may be involved; and(b)[ isolated storage of a hazardous chemical listed in Schedule 2 in a quantity equal to or more than the threshold quantity specified in column 3, thereof.] [Substituted by S.O. 57(E), dated 19.1.2000 (w.e.f. 20.1.2000). ]5. Notification of major accident .-(1) Where a major accident occurs on a site, the occupier shall [within 48 hours notify] the concerned authority as identified in Schedule 5 of that accident, and furnish thereafter to the concerned authority a report relating to the accidents in instalments, if necessary, in Schedule 6.
6. Industrial activity to which rules 7 to 15 apply .-(1) Rules 7 to 15 shall apply to,-
(a)an industrial activity in which there is involved a quantity of a hazardous chemical listed in column 2 of Schedule 3 which is equal to or more than the quantity specified in the entry for that chemical in columns 3 and 4 (rules 10-12 only for column 4), and(b)isolated storage in which there is involved a quantity of a hazardous chemical listed in column 2 of Schedule 2 which is equal to or more than the quantity specified in the entry for that chemical in [columns 3 and 4 (rules 10-12 only for column 4)].7. [Approval and Notification of sites ]
.-(1) An occupier shall not undertake any industrial activity unless he has been granted an approval for undertaking such an activity and has submitted a written report to the concerned authority containing the particulars specified in Schedule 7 at least 3 months before commencing that activity or before such shorter time as the concerned authority may agree and for the purposes of this paragraph, an activity in which subsequently there is or is liable to be a threshold quantity or more of an additional hazardous chemical shall be deemed to be a different activity and shall be notified accordingly.8. Updating of the site notification following changes in the threshold quantity .-Where an activity has been reported in accordance with rule 7(1) and the occupier makes a change in it (including an increase or decrease in the maximum threshold quantity of a hazardous chemical to which this rule applies which is or is liable to be at the site or in the pipeline or at the cessation of the activity) which affects the particulars specified in that report or any subsequent report made under this rule, the occupier shall forthwith furnish a further report to the concerned authority.
9. Transitional provisions .-Where,-
10. [Safety reports and safety audit reports]
.-(1) Subject to the following paragraphs of this rule, an occupier shall not undertake any industrial activity to which this rule applies, unless he has prepared a safety report on that industrial activity containing the information specified in Schedule 8 and has sent a copy of that report to the concerned authority at least ninety days before commencing that activity.11. Updating of reports under rule 10.-(1) Where an occupier has made a safety report in accordance with sub-rule (1) of rule 10, he shall not make any modification to the industrial activity to which that safety report relates which could materially affect the particulars in that report, unless he has made a further report to take account of those modifications and has sent a copy of that report to the concerned authority at least 90 days before making those modifications.
12. Requirement for further information to be sent to the authority .-Where in accordance with rule 10 an occupier has sent a safety report and the safety audit report relating to an industrial activity to the concerned authority, the concerned authority may, by a notice served on the occupier, require him to provide such additional information as may be specified in the notice and the occupier shall send that information to the concerned authority within 90 days.
13. Preparation of on-site emergency plan by the occupier .-(1) An occupier shall prepare and keep up-to-date [an on-site emergency plan containing details specified in Schedule 11 and detailing] how major accidents will be dealt with on the site on which the industrial activity is carried on and that plan shall include the name of the person who is responsible for safety on the site and the names of those who are authorised to take action in accordance with the plan in case of an emergency.
14. Preparation of off-site emergency plans by the authority .-(1) It shall be the duty of the concerned authority as identified in column 2 of Schedule 5 to prepare and keep up-to-date [an adequate off-site emergency plan containing particulars specified in Schedule 12 and detailing] how emergencies relating to a possible major accident on that site will be dealt with and in preparing that plan the concerned authority shall consult the occupier, and such other persons as it may deem necessary.
15. Information to be given to persons liable to be affected by a major accident .-(1) The occupier shall take appropriate steps to inform persons outside the site either directly or through District Emergency Authority who are likely to be in an area which may be affected by a major accident about-
(a)the nature of the major accident hazard; and(b)the safety measures and the "Do's" and "Don'ts" which should be adopted in the event of a major accident.16. Disclosures of information .-Where for the purpose of evaluating information notified under rule 5 or 7 to 15, the concerned authority discloses that information to some other person, that other person shall not use that information for any purpose except for the purpose of the concerned authority disclosing it, and before disclosing the information the concerned authority shall inform that other person of his obligations under this paragraph.
17. Collection, development and dissemination of information .-(1) This rule shall apply to an industrial activity in which a hazardous chemical which satisfies any of the criteria laid down in Part I of Schedule 1 [or listed] in column 2 of Part II of this Schedule is or may be involved.
18. Import of hazardous chemicals .-(1) This rule shall apply to a chemical which satisfies any of the criteria laid down in Part I of Schedule 1 [or listed] in column 2 of Part II of this Schedule.
19. Improvement notices .-(1) If the concerned authority is of the opinion that a person has contravened the provisions of these rules, the concerned authority shall serve on him a notice (in this para referred to as "an improvement notice") requiring that person to remedy the contravention or, as the case may be, the matters occasioning it within 45 days.
20. Power of the Central Government to modify the Schedules .-The Central Government may, at any time, by notification in the Official Gazette, make suitable changes in the Schedules.
