Document Description
The proposed interim measures will consist of the following:
- Removal of the concrete pad and the top five feet of the soils (approximately 43 tons) in the vicinity of the former plating process area using a backhoe and proper hand and power tools. The size of the excavation will be approximately 10 feet by 15 feet by 5 feet deep;
- A competent member of the field staff trained in excavation safety will examine the ground to prevent potential cave-in or collapse. Shoring protection systems will not be required according to Federal and California OSHA guidelines, provided that the excavation depth does not exceed 5 feet. Also, the excavation is not close to any of the building walls so structural integrity of the building will not be affected by the excavation activities;
- Stockpiling excavated material and/or placing the material in roll off bins. Excavated material will be covered with plastic sheeting at the end of each day;
- Conducting dust suppression, as necessary (watering of excavation, covering of stockpiles), and dust monitoring during excavation and backfilling activities;
- Confirmation sampling to ensure that residual levels of lead are below the residential exposure level of 150 mg/kg pursuant to the California Environmental Protection Agency's California Human Health Screening Levels;
- Proper disposal of personal protective equipment (PPE);
- Disposal of excavated soils and other waste (such as decontamination water). Samples of each waste stream will be collected and submitted for disposal profiling. Following receipt of analytical results for profiling of the waste, an appropriate facility for disposal will be identified, and a licensed disposal contractor will transport the containers to the designated disposal facility in accordance with all applicable rules and regulations. If lead concentration of the excavated soil is above 350 mg/kg, it will be disposed to a Class I landfill pursuant to Health and Safety Code section 25157.8.
- Backfilling using approximately 43 tons of clean imported material.
- Compaction of the backfilled material; and
- Restoration of the floor with new concrete.

Reasons for Exemption
The site is not listed in the Hazardous Waste and Substances Sites Lists pursuant to Government Code 65962.2. The project is a small removal action to eliminate the threat of release of hazardous substances by excavation and/or offsite disposal of the contaminated soil which will cost less than $1 million. Removal, transportation, and disposal of lead contaminated soil, backfilling of the excavation, and replacement of the concrete slab is estimated to cost approximately $26,000.00.
1. The project is of small scale (less than ten truckloads of soil) and limited duration. The project will be completed in three to four weeks time.
2. Dust suppression measures (watering of excavation as necessary, covering of stockpiles) and dust monitoring for particulate emissions during excavation and backfilling activities. The excavation area will be surrounded with barricades delineator posts or barricade yellow caution tape. No entry to the excavation area will be permitted.
3. Activities will be conducted pursuant to the IM Workplan and consistent with the Health and Safety Plan provided in the IM Workplan.
4. Excavation and grading will occur under a permit from the City of Stockton. Work activities will be conducted on weekdays between the hours of 7 am and 5 pm daily. Trucks will be controlled to avoid peak commute hours. All equipment and trucks will be decontaminated prior to leaving the site. Truck traffic will be liited to 5 trucks per day and will follow a route through industrial areas using major arterials as follows: leave 1848/1856 Field Avenue; make a right onto Field Avenue; make a left onto Buena Vista Avenue and then an immediate right onto W. Fremont Street; and onto I-5 freeway. If lead concentration of the excavated soil is above 350 mg/kg, it will be disposed to a Class I landfill.
5. Based on consultations with the City of Stockton Building and Planning Divisions, the Holt-Atherton Archive at University of the Pacific (UOP), and the San Joaquin County Museum, the site is not located in an area of known cultural resources.
