2-021 -A Site Strategy- French Camp Slough 2-021 -A County and Thomas Guide Location NOAA CHART Latitude N Longitude W SF Bay and Delt San Joaquin 18661 SACRAMENTO/SAN JOAQUIN RIVER 3755 121 19.2 CONCERNS and ADVICE to RESPONDERS: Last page update: 7/1/2005 Penetration into marshy areas,woody cover, riprap, and animal and invertebrate burrows in levees, islands and uplands. Vegetation cleaning problems. HAZARDS and RESTRICTIONS: Slips,trips and falls on riprap and steep levees. Regarding boat handling, beware of shallows, snags and mud bars. Poison Oak. SITE STRATEGIES Strategy 2-021.1 Objective: Exclusion/Containment booming at mouth to prevent entering or leaving the slough mouth: Stop oil entry on incoming tide or oil escapement if originating within slough. Set boom across slough mouth. Anchor one boom end near downstream riprap bank. Anchor upstream boom end to forested tip, leaving a trailing boom length to maintain seal during tidal change. Add 1 mid boom anchor tc maintain best deflection angle. Skim at riprap closure if spill is in slough. Strategy 2-021.2 Objective: deflection to collection away from slough to opposite side of San Joaquin River when oil is coming down-river from upstream. Anchor boom diagonally upstream 100'+from mouth diagonally downstream and across the San Joaquin River to west side riprap levee (shallows). Skimming (Shore-Side Skimming) collection on west side. Be prepared to close mouth with additional boom if oil escapes. A backup deployment with equal equipment may be necessary. Use 50ft of Oil Snare (OS), 100ft of sorbent boom to collect any oil that may accumulate. Contact IC if oil accumulates in skimmable quantities. Strategy 2-021.3 Objective: Oil Recovery by skimming Deploy skimmer if oil accumulates in skimmable quantities. Consult with IC prior to initiating this strategy.

Levee roads border this site on north south and west. North&east levees can be reached via 1-5 to Charter Way/Hwy 4 to levee via water 2 miles south of Stockton Port on the San Joaquin River. A six mile+dead-end slough extending from the mouth on the San Joaquin River easterly with main stem and branch, Walker Slough,to 1-5(ACP boundary). Both branches extend well east of 1-5. LAND ACCESS: LEVEE NORTH IS PAVED; OTHERS ARE NOT WATER LOGISTICS: Shallow and shallower, snags Limitations:depth,obstruction Launching, Loading, Docking Stockton harbor area marina facilities. and Services Available: FACLITIES,STAGING AREAS,POSSIBLE FIELD POSTS AND EQUIPMENT AVAILABLE: Adjacent levees should be adequate as long as roads are passable. Otherwise transport material by skiff(2 miles). COMMUNICATIONS PROBLEMS: none known ADDITIONAL OPERATIONAL COMMENTS: ACP 2-SF Bay&Delta 9850.1 -14 October 1,2014
