The CONTRACTOR will be responsible for proper abandonment of monitoring xxxxx installed by CONSUL TANT at the pump station. A Phase I Environmental Site Assessment report was conducted as part of the 10% Engineering Design Report for North City to San Xxxxxxx Conveyance System. The Phase I concluded that Phase II environmental site assessment is required. The CONSULTANT shall prepare Phase II environmental site assessment for the San Xxxxxxx Conveyance System. The scope Morena Pump Station and fee for such of this effort shall be included in the fee estimate. Since the Phase I ESA is not completed for the Miramar project, no Phase II EAS is included in this task for the Miramar project. CONSULTANT shall also perform an initial evaluation of environmental considerations related to pipeline alignment and construction techniques. The Phase II Environmental Site Assessment report shall present all findings, conclusions and recommendations relevant to design, including a specific discussion of: • Unique or unusual site/coordinator conditions that suggest any special design that may be required, • Groundwater handling during construction, • Contaminated soil or groundwater, • Develop a soil, groundwater and vapor management plan to be implemented during construction, and • Provide a map which shows locations of potential contaminant sources relative to the proposed alignment. For the Phase II Site investigations and reporting, CONSULTANT will: • Review existing documentation including Phase I ESA and files obtained from Regulatory agencies as identified in the Phase I ESA performed by Xxxxx and Xxxxxxxx (B&C). • Perform a site visit to locations identified as REC Sites/Cases with High Potential Impact in the B&C Phase I ESA to identify and map proposed boring locations, identify potential constraints to drilling, and assess any needed changes to assumptions made in scoping. Site visits will not be conducted at USMC Miramar Air Station or the former USMC Camp Elliot due to potential for unexploded ordnance (UXO) associated with these sites. • Develop a sampling and analysis plan (SAP), Quality Assurance Project Plan (QAPP) and health and safety plan (HSP) (draft and final). All sites considered for Phase II Site Investigation by CONSULTANT will be combined into a single SAP, QAPP, and HSP, respectively. • Prepare traffic control plans and seek required permits for drilling, as required, in public right of way. • Respond to one consolidated set of comments on the draft plans (HSP is considered to an internal document and is not anticipated to be reviewed, even though it will be submitted with other plans. • Subcontract with qualified environmental driller and California certified analytical laboratory to perform required investigation, disposal of up to five 55-gallon drums of decontamination water and soil cuttings, and chemical analysis of soil and groundwater. • Ensure utility clearances are done in advance of each site to be drilled, as required by local and state jurisdictions • Upon receipt of analytical data, CONSULTANT will perform a Level II data quality review of the chemical data to determine its suitability for use in design and construction. • Prepare a combined report for all sites associated with the Phase II Site Investigation (draft and final). • Prepare recommendations for use by design teams in developing pipeline design as part of this report. • Respond to one set of consolidated comments on the draft report. To support the design and risk mitigation CONSULTANT will: • Participate in up to 10 meeting with the design team to assess, map and discuss mitigation of contaminated materials during construction. These meetings will be up to 4 hours each, with 4 hours of preparation and 4 hours of the post-meeting activity for two people. • Review specifications for management of contaminated soils and dewatering water. • Develop a contaminated media management plan for the corridor and for up to 10 specific locations evaluated as part of the Phase II Site Investigation. The general assumptions that apply to the Phase II Environmental support includes, but is not limited to the following: • The Phase I ESA prepared by B&C represents the potential sites along that corridor that require Phase II investigation in advance of design and construction. This scope includes 10 of the sites considered by B&C to be the “RECS with High Potential Impact”. Should a review of the report or other documents indicate that additional sites require investigation in order to mitigate potential design or construction risks, CONSULTANT will prepare a supplemental scope and budget for these investigations. • Two of the sites identified by B&C relate to unexploded ordnance (UXO). This Phase II Site investigation does not include any work related to UXO. This work is being performed by others. Thus, no work will be performed in the vicinity of the USMC Miramar Air Station or the former USMC Camp Elliott, as described in the B&C report (2015). • The CITY will seek site access to private property as required. If site access to private property is not allowed, CONSULTANT will perform drilling activities in the public ROW and will provide qualifications and assumption in reporting based on areas able to be accessed. • The CITY will provide storage for up to five 55-gallon drums of decontamination water and soil cuttings for up to 90 days until analytical results are received, waste manifests are completed, and waste drums are transported for disposal. • All drilling will be done using geoprobe.
