ExxonMobil M-70 Pipeline Replacement under the Santa Clara River
Document Type
MND - Mitigated Negative Declaration
Present Land Use
The Santa Clara River is designated as a Sensitive Ecological Area (SEA) #23. The surrounding area zoned as A-2-5, heavy agricultural use with a parcel size of greater than five acres.

Document Description
The proposed project will replace ExxonMobil's existing M-70 crude oil pipeline in the Santa Clara River bed in Santa Clarita, with a new pipeline of the same diameter by boring approximately 55 feet beneath the lowest part of the riverbed at this location for a length of approximately 1,300 feet. The objective of the proposed project is to rebury the pipeline to a level well below the scour depth of the Santa Clara River since recent substantial scouring has resulted in the current level of cover over the pipeline being somewhat less than five feet of sediment. The installation and testing of the new pipeline will require approximately four weeks.
