Deliverable: • Geotechnical Report INITIAL. SITE ASSESSMEN'r FOR HAZARDOUS WASTE The Planning Center is proposing a Modified Phase I Environmental Site Assessment for the Warner Avenue widening project between Main Street and Grand Avenue. The assessment will assist in identifying environmental hazards related to current and past operations on the site. The scope will include a review of historic aerial photographs and topographic maps, site visit, and review of a regulatory database report and city directory. Government records (as available) including: NPL site list; Federal CERCLIS list; Federal CERCLIS NFRAP site list; Federal RCRA CORRACTS facility list; Federal RCRA non-CORRACTS TSD facilities list; Federal RCRA generators list; and Federal ERNS lists will be reviewed Additionally, California State lists of hazardous waste sites identified for investigation or rennediation (as available) wilt be provided. The Planning Center will perform the following detailed scope of services to complete our Transaction Screen Process Report • Visual observations of site conditions, to evaluate the nature and type of activities that have been or are being conducted at and adjacent to the site, in terms of the potential for release or threat of release of hazardous substances or petroleum products. • Review of federal and state environmental database information within the ASTM- specified radii from the subject property using a database service to access records. Use of 7.5-minute topographic maps to evaluate the sites physical setting. • Review of federal and state environmental files pertaining to the subject site and nearby sites with the potential to impact the subject site. • Review of the following sources of historical use information: ? Aerial Photographs ? Historical Topographic Maps • Contacts with state and local agencies regarding the site and surrounding properties and structures. An evaluation of business environmental risk associated with a parcel of commercial real estate may necessitate investigation beyond that identified in this environmental site assessment. The proposed assessment does not address whether requirements in addition to appropriate inquiry have been met in order to qualify for CERCLA's innocent landowner defense. The proposed assessment does not address requirements of any state or local laws or of any federal laws other than the appropriate inquiry provisions of CERCLA's innocent landowner defense. Users are cautioned that federal, state, and local laws may impose environmental assessment obligations that are beyond the scope of this practice. Users should also be aware that there are likely to be other legal obligations with regard to hazardous substances or petroleum products discovered on property that are not addressed in this practice and may pose risks of civil and /or criminal sanctions for non-compliance. No subsurface explorations or chemical testing of soils or groundwater will be performed during this assessment. Therefore, our conclusions regarding the evidence of recognized environmental conditions will be based on observations of existing visible conditions, and on our interpretation of site history and site usage information.
