The Board of County Commissioners have now made this a condition to their approval of <br />the Special Use Permit. Also, an inspection by the Division of Minerals and Geology has yielded <br />similaz comments. We have discussed your recommendation with the landowners, Raymond and <br />Robert Dellacroce and they understand your cotrcem for inhibiting noxious weed growth. <br />Robets Dellacroce insides on the tatlch and is primarily responsible for the operations. <br />Robert has attended local seminars focusing on the knapweed species and has received EPA <br />certification for private use of pesticides and herbicides. The previously reclaimed area above (west <br />of) the site has received a Banville treatmem once during the Spring season of 1993. Mr. Dellacroce <br />intends to utilize different herbicides for the next growing season, according to his current certification. <br />Grass seeding has been implemented to provide competition for the ICnapweed, and the lower pastures <br />are also grazed. Topsoil will not be removed or relocated from the proposed site, thus reducing the <br />possibility of seed spreading during operations. <br />We understand that the next step of a weed control program is an exchange of information <br />between the landowner and the local regulatory officials. Please accept this letter as the applicant's <br />initial offer of compliance and forward to the proper County agency. If you have specific questions, <br />please contact Robert Dellacroce at his residence, (719)'181-2452. <br />Yours tnily; <br />~~~~~,~~ <br />Mazk L.
