The Discharger has recently completed construction of a Title 27 final cover <br />under Cleanup and Abatement Order No. R5-2006-0707. The Report provided a topographic <br />map, slope cross-sections, and calculations to verify that the final slopes were shallower than <br />3:1 (horizontal to vertical). Under Title 27 §21090, a slope stability analysis is required when <br />the final cover slopes are steeper than a horizontal to vertical ratio of three to one. Based on <br />the Discharger's comparison of the final slopes to the Title 27 requirements, the Discharger <br />concluded that a slope stability analysis was not required. The Report was certified by a <br />California licensed Civil Engineer. <br />Based on staff's review, the Report is complete. <br />If you have questions, please contact me via email (mboyd waterboards.ca.gov) or telephone <br />at (916) 464-4676. <br />s <br />Mary L.
