During 2003 the west mine vent shaft was sealed and returned to approximate original contour and seeded. Vegetation has flourished since initial reclamation efforts and passed all success criteria in 2019 and 2021. The area surpassed the total plant cover success criterion of>_54%with 79.8%in 2019 and 54.6%in 2021. (Table 1 in attached Cedar Creek report). The annual (total) herbaceous production success criterion >_ 405 per acre (90% of the technical standard value of 450 pounds per acre)was surpassed with 1089 pounds per acres in 2019 and 549 in 2021 (Table 1 in attached Cedar Creek report).
