Section 289.245 - Standards for successful revegetation

(a) The standard for successful revegetation shall be the percent of ground cover of the vegetation which exists on the site. The Department will not approve less than a 70% ground cover of permanent plant species. No more than 1% of the total area may have less than 30% ground cover. A single or contiguous area exceeding 3,000 square feet may not have less than 30% ground cover.

(b) Trees, woody shrubs or deep rooted plants may not be planted or allowed to grow on the revegetated area of capped sites, unless otherwise allowed by the Department in the permit based on a demonstration that roots will not penetrate the cap or drainage layer.
