targeted areas may increase and consequently Map #3 may be revised as part of this Technical Revision. Stipulation #2 limits the maximum disturbance to 25 acres pe ding any adjustments to the financial warranty. The Conversion, your adequa y letter of 14 May 1997, and the reply of 18 May 1997, left some remaining is ues to be attended to at the time of the planned technical revision. Those ~ tters are attended to here-in, in part or in whole, some of which cannot be fully determined until the Division inspects the site and verifies th ground interpretations with the photo-survey of the property. The aerial photograph provided in this Technical Revision is a unique instrument that allows for surrey level accuracy in the identific tion and measurement of irregular boundaries of disturbed land. The lines c rrespond to actual ground locations accurate enough to receive a surveyor's c rtification. An uncorrected aerial photograph provided the datum for the original ubmittal, but with the increased accuracy of the ground controlled and digitally corrected aerial datum of 1997, new measurements and ground interpretatio s derived therefrom must be attended to. The following table is a comparis n of the approximations derived from the uncorrected aerial photograph October 1996 with that of the corrected aerial photograph of November 1998 as measured with surveyed ground control and enhanced CADCAM so are: OCTOBER 1996 AREA DESCRIPTION NOVEMBE 1997 7.314 Pre-Law Disturbed Land 7.79 2.282 Mar inall Affected Land 0.79 2.729 Roads 2.30 5.745 Affected Lands/guar 8.67 0.000 Stora a 1.12 18.07 ~ = 2.56 20.63 Since operations remain comparatively unchanged from October 996, the increase in acreage of 2.56 acres is predominantly attributable to ncreased accuracy of the ground controlled corrected aerial photograph a d related interpretations from the enhanced image that was measured by CADCAM internally within the computer. Interpretation of the new aerial caused a majority of the Marginall Affected Lands category to drop out. Regardless, a comparison of Marginall Affected and Affected/Quarry lands resulted in a difference of 1.393 acres Prelaw Affected Lands were slightly larger than originally estimated at 0.4 6 acres. Road areas decreased by 0.429 acres. 2 Rocky Road Investment, Inc. Technical Revision of 30 January 1998 for M8 -210.
