The Southfield Mine was inspected for compliance with relevant requirements for Phase <br /> III bond release in relation to the PAP. Determination of revegetation success criteria is <br /> discussed under Section 2.05.4 of the Southfield Mine PAP that meets the requirements <br /> of Rule 4.15.11. Vegetative productivity is considered successful when vegetative <br /> biomass on the reclaimed area is greater than or equal to 90 percent of the vegetative <br /> biomass from the reference areas. Successful species diversity is determined using the <br /> results of vegetative cover data. Species diversity is considered adequate when the four <br /> dominant species,based on plant cover, comprise no more than 80 percent of the total <br /> species composition per Rule 4.15.8(5). Woody plant density success values are specific <br /> to the parcel and are evaluated using a weighted average summation of transplant clump <br /> density and seeded area wood plant density. <br /> Vegetation sampling was not performed and productivity and woody plant density was <br /> not evaluated at the Magpie Diversion. The Magpie Diversion is a permanent post- <br /> mining channel and there are no associated vegetation requirements of productivity and <br /> woody plant density. <br /> Revegetation Success -Productivity <br /> Per Rule 4.15.11(2), "Demonstrations of sample adequacy and revegetation success for <br /> cover and productivity shall be made with one of the following statistically valid <br /> approaches in (a), (b), (c) or(d)." As discussed in subsection Vegetative Cover Success <br /> Standard under Phase II observation and findings of this document, sample adequacy <br /> cannot be achieved for site specific cover data as well as productivity data due the size of the <br /> applicable remaining areas of the Southfield Mine. <br /> Revegetation Success Woody Plant Density <br /> Valid approaches for demonstrations of sample adequacy and revegetation success for <br /> woody plant density is discussed in Rule 4.15.11(3). In order to achieve sample adequacy <br /> for Rule 4.15.11(3), (a) of this rule requires a minimum sample size of thirty. Rule <br /> 4.15.11(3)(b) requires a minimum sample size of seventy-five and a minimum quadrat <br /> size of 100 square meters. <br /> Additionally, Rule 4.15.11(3) allows for the same statistical approaches used in Rule <br /> 4.15.11(2) for vegetation productivity to be used for determining woody plant density. As <br /> discussed under the requirements for determining sample adequacy for productivity, <br /> Southfield Mine <br /> Permit No.C-1981-014 June 7,2024 <br /> 12 <br />
