I have enclosed <br /> a letter showing our procedure. Also I may note we use a degreaser <br /> to help in our cleaning method. <br /> As regards haardous waste generated it will hauled away <br /> by California oil Recyclers INC. <br /> As far as purging and ierting methods we first air the tank <br /> out untill we get the L.E.L. to safe levels then we inert it <br /> by using 20 Lbs. dry ice per 1000 gallon. <br /> As regards soil samples they will be taken 24 inches below <br /> bottom of tank in undisturbed soil. <br /> Y'r,�/o leJ kc /'// �.� J—i,�tLo fj Chi�r s" %L �c :I�l Hca c•��s/%.;-L ;� . <br />
