SUPPLEMENTAL INFORMATION<br />

PART 3: AENV SIRS – ROUND 2<br />

Question No. 44<br />

Request Volume 1, SIR 379b, Page 14-22.<br />

AENV SIRS 44 – 78<br />

Section 13.1<br />

In the EIA Volume 5, Appendix 5-2, Section 1.6, Page 18, Shell states that<br />

reconstructed soil performance will mimic natural soils over time. In the <strong>Pierre</strong><br />

<strong>River</strong> <strong>Mine</strong> SIR Response, Shell references personal communication with L.<br />

Leskiw in July 2008, discussing the development of an incipient LF horizon on<br />

some of Suncor’s older upland reclamation areas and juvenile profile<br />

development (LF horizons and discontinuous Ae horizons) on direct placement<br />

reclamation areas at Syncrude.<br />

44a How old are the reclamation areas at Suncor and Syncrude where the juvenile<br />

profile development described above was found?<br />

Response 44a The reclamation areas discussed in the personal communication were between 20<br />

and 30 years old.<br />

Request 44b What is the Land Capability Class for each of the juvenile profiles described<br />

above?<br />

Response 44b The land capability class was not discussed in the personal communication of<br />

July 2008. The research referred to in this personal communication is the<br />

Nutrient Biogeochemistry II project currently being conducted through<br />

CONRAD. The results of this study are not available for public disclosure.<br />

Request 44c What was the reconstructed profile of the juvenile soils described above?<br />

Response 44c The reconstructed profile was not discussed in the personal communication of<br />

July 2008. The research referred to in this personal communication is the<br />

Nutrient Biogeochemistry II project currently being conducted through<br />

CONRAD. The results of this study are not available for public disclosure.<br />
