ORDER : Y.K. Sabharwal, CJI. I.A. No. 179 in Writ Petition (C) No. 13029/1985 : 1. The question under consideration is about the manner of calculating pollution in the petrol cars in Delhi. With the assistance of the learned Amicus Curiae and other learned counsel appearing in the case, we have perused the E.P.C.A. Reports dated November, 2004, December, 2004, March, 2005 and November, 2005, as also the stand of the Government of the National Capital Territory of Delhi reflected in the affidavit of Mr. S.N. Sahai filed in May, 2005. We have also perused the response filed by the Society of Indian Automobile Manufactures. At this stage, the question is of introducing the Lambda Test to check the cars from pollution angle at P.U.C. Centres. There are about four hundred such centres in Delhi. According to the stand of the Delhi Government, the introduction of new technology required to be used to undertake such a test, in a phased manner, would need a period of six months. At this stage, it is not in question that it is essential to implement the Lambda Test and, therefore, it is necessary to introduce the technology at the P.U.C. Centres so that they are in a position to undertake such a test. The question as to what shall be the cut-points, i.e, 0.03, 0.05, 0.07 or 0.09, would be examined after the technology has been installed at the P.U.C. Centres. Meanwhile, the pilot tests can also go on so that when the technology is introduced, this Court is also in a position to know the further results of the pilot tests and keep that also in consideration while fixing the cut- points. 2. We hope that the Delhi Government will be able to introduce this technology by the end of April, 2006, and, by that time, we will have a further report on this issue from E.P.C.A. List the matter in the first week of May, 2006. Parking Policy (I.A.No.226): 3. The Chief Secretary of Government of National Capital Territory of Delhi in the affidavit filed in this Court on 14th July, 2005 has referred to a draft report on parking policy in Delhi submitted to the Chief Secretary by the sub-Committee appointed by him. That draft report of June, 2005 prepared by Urban Development Department of Government of Delhi has also been placed on record. That draft report of June, 2005 prepared by Urban Development Department of Government of Delhi has also been placed on record. The EPCA in addition to its report of July, 2004 has filed a supplementary report being Report No.18 of November, 2005. In substance, except few suggestions, the draft report seems to be acceptable to EPCA. The EPCA has recommended that the Delhi Government must be asked to finalise and issue the parking policy to all agencies for its implementation. It has further been suggested that the Delhi Government and other agencies - MCD, NDMC, PWD and DDA - must finalise the priority action emanating from the policy along with the suggested directions given in Report No.18 by EPCA and these shall be filed in this Court for implementation. Certain other suggestions have also been given. 4. Having regard to the affidavit of the Chief Secretary, the draft policy and the report of EPCA, we direct that the Chief Secretary of Delhi Government shall call a meeting of all concerned agencies, discuss the issue with the said agencies and file in this Court a finalised parking policy, after discussing the policy and report with EPCA. The finalised policy with priorities and other requisite action plan shall be filed in this Court within four weeks. 5. This matter is adjourned, to be taken up after five weeks. Report No.17: 6. Supplementary report of the EPCA, Report No.17/2005, is taken on record. It deals with the matter in regard to the safety as certain incidents of CNG bus fires were reported. We are told that the suggested measures are being adopted by the agencies and at present no further directions are necessary. Report No.12: 7. For the present, no further directions are necessary.
