Rules and earlier instuctions regarding these cut-offdates are:

of the extent excluding roads(second deduction) should be resewed and gifted. This case

is not eligibie for first deduction.

(b) In case of extent of site applied for permission is upto i0,000 sq.m., then it has to beascertained whether the site extent was in existence as such i.e., having the same extentprior to the either of the above said cut-off date, as the cirse may be. If not, then thecalculation for determining the OSR requirement should be as follows:

(i) If the extent of the original site prior to the said cut-off date is upto 3,000 sq.m., thenthe benefit of first deduction of 3,000 sq.m. shall be applied and hence no necessityfor allocation of OSR.

(ii) If the extent ofthe original site prior to the said cut-off date is above 3,000 sq.m. andupto 10,000 sq.m., then the benefit of first deduction shall be portion of 3,000sq-monly and which shall be the extent of splitting 3,000 sq.m, in the same proportion asthe site applied for permission was sub-divided from the original site. Then after thisfirst deduction the resulting site excluding roads to be taken up for calculating the10% osR.
