This MRP is issued pursuant to California Water Code Section 13267. Support Terminals Operating Partnership LP (hereafter Discharger) is required to comply with this MRP. The Discharger shall not implement any changes to this MRP unless and until a revised MRP is issued by the Executive Officer. In addition to this MRP, groundwater sampling and reporting outlined in MRP No. 5-01-819 is still required.

The time, date, and location of each grab sample shall be recorded on the sample chain of custody form. REMEDIATION PILOT STUDY MONITORING As shown on Attachment B,there are two extraction wells,three injection wells, and six monitoring wells at the facility. The groundwater monitoring program for these 11 wells and any wells installed subsequent to the issuance of this MRP, shall follow the schedule below. Monitoring wells with free phase petroleum product or visible sheen shall be monitored, at a minimum, for product thickness and depth to water. Sample collection and analysis shall follow standard EPA protocol. A.
