These test pits will be backfilled whi <br />the track hoe is on site in a manner conducive to reclamation this fall. I <br />2) The total disturbed that may requiring reseeding is a maximum of 1 -acre. The additional area disturbed beyond <br />the pits themselves have already been accounted for (total pit area of only 0.15 acres maximum — 0.0073 acres <br />each). Actual disturbance is expected to be much less than stated. <br />-9 MUMMOZ07murs Am <br />hftps:llmai|.google.com/mail/ul0/?ui~��e29129fcb5&view=pt&search=inbox&th=1 im|~15767bO4d8c7Odd4 1/2 <br />
