(Lafarge) <br />is requesting a Technical Revision (TR) to our permit for the State Pit located near Pueblo, <br />Colorado in Pueblo County. The TR is in response to the Division's request for a weed control <br />plan for tamarisk including control methods to be implemented and a schedule for when the <br />various control methods will be employed. <br />Lafarge is proposing use of the herbicides Arsenal and Habitat to control the tamarisk. Habitat <br />will be used in areas where spray could come in contact with water. The spraying will occur <br />before the end of September, as the herbicides are foliaz applications and only effective while the <br />plant has green leaves. Future applications, if necessary, will occur during the late summer <br />and/or early fall. The spray will be applied by hand. <br />Lafarge has successfully treated other sites with the proposed actions and believes the TR meets <br />the Division's requests, It is our understanding that this TR for control of tamarisk does not <br />require a fee because it is being submitted by 3une 27, 2005. If you have any questions or seed <br />additional information, please do not hesitate to contact me at 303-657-4118. <br />Sincerely, <br />,~ <br />Philli J'~/ <br />P Y <br />Land and Lease Specialist <br />Cc: Rusty Cochran - Lafazge <br />( 1~ s <br />`, <br /> <br />~; 2: <br />,Y, y, <br />.i <br />,;,.: <br />,, <br />... <br />~;, <br />;,;; <br />LAFARGE NORTH AMERICA INC. ^ Lafarge Asphalt COngete 8 Aggregates <br />10170 Church Ranoh Way, Suhe 200, Westminster, Colorado 00027 <br />Telephone: (303) 657000 Fdcsimile: (303) 657.4097 <br />
