As stated above. these areas of known impact do not extended more than. 50 feat south of the property line and occur between depths of 5 and 15 feet_ Keusc of Excavated Snil Because this affected soil does not pose an unacceptable risk to human health or the environ- ment, it can be reused at the site. However, a petroleum hydrocarbon odor and crude oil residue may be present in this soil;therefore, consideration should be given to where the soil is placed. Potential reuse options include placement of the soil back into in the: subsurface (e.g., in trenches and other excavations) or underneath surface coverings (e.g., roads, parking areas, or other paved structures). The following guidelines are recommended: (1) if used as trench backfill, do not place affected soil in contact with underground utilities; (2) do not place affected wail as backfill for excavations if geotechnical properties are insufficient-, and (3) do not place shallower than 2 feet below ground surface w less covered by pavement. If affected soil cannot be reused in the subsurface or underneath surface coverings, the soil should be stockpiled separately from other non-affected soil excavated at the site. and CPL should be contacted(see contact list on last page). A,,=rding to the San Joaquin County Air Pollution Control District, no permit to stockpile this soil is required by them. If required by a regulatory agency, CPL will arrange to have the affected soil removed for off-site disposal (e.g., landfill). If affected soil is disposed of off site without CPL's involvement, CPL will not be responsible for any cost or liability associated with such disposal. In addition, it is important to consult with the disposal facility regarding potential restrictions for accepting petroleum hydrocarbon-affected soil. Health and Safety IS.5urt Because the affected soil does not pose a human health threat based on the Dividend risk assess- ment, construction workers or others who encounter and handle affected soil do not require any unique health and safety training above standard requirements for performing their job.
