M. Scott Mansholt -2 - 6 May 2009 <br /> No f=urther Action Required Deteeation <br /> Mountain House Development Site#4 <br /> associated with features within the road ROW. SAIC concluded that the residual crude oil <br /> remaining at the Site does not pose a threat to human health for the construction/trench <br /> worker scenario. <br /> Central Valley Water Board staff received the site specific Soil Management Plan (SMP), <br /> dated 28 August 2008 that provides guidance for interested parties who may conduct <br /> excavation and/or maintenance activities at the Site in the future. The SMP, which designates <br /> Chevron as the responsible party for any issues that arise related to the crude oil leaks, was <br /> submitted to the interested parties identified at the Site. <br /> Property owner(s) determined to have been affected by crude oil leaks from the historical <br /> pipelines located on or near the referenced site, were notified by certified mail of the proposed <br /> closure. On 18 March 2009, Central Valley Water Board staff notified interested persons of <br /> their opportunity to provide comments to Chevron's 22 October 2008 request for NFAR <br /> determination. No comments were received during the 30-day comment period. <br /> The reports concluded that site assessments, characterization, and risk assessment have <br /> provided the appropriate technical data and rationale to support a NFAR determination. <br /> If existing, additional, or previously unidentified chemical constituents associated with the <br /> former crude oil pipelines at Mountain House Development Site #4 cause or threaten to cause <br /> pollution or nuisance or are found to pose a threat to public health or water quality, then: 1) <br /> nothing in this determination is intended or shall be construed to limit or preclude the Central <br /> Valley Water Board or any other agency from taking further enforcement action, and 2) this <br /> letter does not relieve Chevron of any responsibilities mandated under the California Health <br /> and Safety Code and the California Water Code. Nothing in this determination shall constitute <br /> or be construed as a satisfaction or release from liability for any conditions or claims arising as <br /> a result of past, current, or future operations at Mountain House Development Site #4. <br /> If you have any comments or questions, please contact Dean Hubbard at (559) 445-5179. <br /> G�- 4ZW, <br /> Pamela C.
