Memorandum <br /> <br />To: Byron Walker <br />From: Janet Binns <br />Date: 07/24/02 <br />Re: Colowyo, C-1981-019 <br />CC: Dan Hernandez <br />File: C:/jhb/Team/Colowyo/TR-57.doc <br />I have reviewed Colowyo's submittal of TR-57, revised page 4.15-1 (July 8, 2002), regazding proposed <br />change to revegetation monitoring schedule. <br />Colowyo proposes to visually monitor reclaimed vegetative stands the first growing season after planting; <br />i.e. the summer following a Fall seeding, or the summer following a Spring seeding. A visual assessment <br />will allow Colowyo to determine if the seeding effort has germinated and is becoming established, if a <br />noxious weed problem is presenting itself, or if other significant problems aze exhibiting themselves. This <br />will allow the operator to take corrective measures eazly in the vegetation establishment process. Colowyo <br />will not take frequency measurements at this early stage of re-vegetation. This proposal is acceptable to the <br />Division. <br />Colowyo proposes to conduct additional monitoring in areas seeded 7 years or longer. This proposed <br />monitoring may help the operator determine an areas readiness to schedule bond release sampling. <br />Colowyo's proposal is in agreement with Rule 4.15.1(4) and acceptable to the Division. <br />
