Services Provided and Implementation Schedule/Proposed Work Plan
<br /> For this contract, Rincon will perform Phase I ESAs in accordance with ASTM E1527-13,Standard Practice for
<br /> Environmental Site Assessments: Phase 1 Environmental Site Assessment Process, but using strategic
<br /> approaches tailored to meeting the City's needs. Phase I ESAs will be performed by support staff under the
<br /> supervision or responsible charge of a qualified Environmental Professional as defined in ASTM E1527-13.The
<br /> scope of work for a Phase I ESAs is detailed in ASTM E1527-13 and consists of the following tasks:
<br /> • Record Review. A records review will be conducted to help identify potential environmental liabilities
<br /> associated with current and past uses of the project site. The review will include both environmental
<br /> information and historical use information readily available in public records and the records maintained by
<br /> the City, as well as performing a computer database records search in accordance with minimum search
<br /> distances and required database specified in ASTM E1527-13. Environmental agency file reviews will be
<br /> conducted for unauthorized release sites that fall within a project site, adjacent properties, or nearby
<br /> properties that would be expected to impact the site. Applicable historical use information will also be
<br /> assessed by a review of two or more of the following:Sanborn Fire Insurance maps, city directory listings,
<br /> USGS topographic maps, aerial photographs, and building permit files. In addition, property tax records,
<br /> chain of title reports,or lien search reports,will be reviewed, if provided by the City.
<br /> • Site Reconnaissance. Rincon will coordinate with the City to appropriately access a site and conduct a
<br /> reconnaissance to identify obvious potential environmental liabilities. Immediately adjacent properties(as
<br /> accessible)will be visually inspected from public thoroughfares.Site use practices that may have impacted
<br /> the property will be reviewed(e.g.,storage tanks,drums and containers,chemical/waste storage).
<br /> • Interviews. In coordination with the City, and upon authorization, Rincon will conduct interviews with site
<br /> owners, or a designated representative of a site owner,past site owners,and occupants/tenants to obtain
<br /> additional information regarding past and present site uses as they may have affected the property.
<br /> • Reports. Rincon will prepare reports in accordance with the requirements of ASTM E1527-13 and will
<br /> document the information and findings of the research and reconnaissance, include a series of maps
<br /> identifying existing site and nearby land uses,and provide conclusions regarding the potential presence and
<br /> impact of environmental site conditions. The Phase I ESA report will be signed by the Environmental
<br /> Professional and will include the required declaration statement.
<br /> Phase II Environmental Site Assessment
<br /> The objective of a Phase II ESA is to evaluate the nature and extent of contamination and to assess the
<br /> significance of the contamination relative to established threshold levels or some other risk-based criteria.Phase
<br /> II ESAs will be developed by the Phase II ESA TA Manager in coordination with the project manager, who is a
<br /> California-licensed Professional Engineer, and the Principal-in-Charge, who is a California-licensed Professional
<br /> Geologist and Certified Hydrogeologist. We understand that a Phase II ESA project under this contract may
<br /> involve assessment of soil,groundwater,soil vapor,water pipelines and related infrastructure materials,and/or
<br /> building materials.
<br /> Assessment is typically conducted in phases, which may include a preliminary site assessment, one or more
<br /> subsequent phases of assessment, periodic monitoring, risk assessment, and an evaluation of risk-based
<br /> cleanup levels. The assessments also involve working within established regulatory agency guidelines for
<br /> assessment and reporting.That said, Rincon approaches Phase II ESAs holistically;we balance the benefits of a
<br /> phased approach with the benefits of optimizing data collection during a single mobilization to meet project
<br /> deadlines.While each project will be scoped,developed,and implemented consistent with the City's needs and
<br /> relevant site-specific information,our approach to Phase II site investigations will include the following tasks:
<br /> • Work Plan. After the initial kick-off meeting with the City (and potentially a regulatory oversight agency, if
<br /> applicable),Rincon will develop a work scope to achieve the established assessment goals.A work plan will
<br /> be prepared that details project objectives;site history and background;regulatory framework;pre-field work
<br /> tasks(e.g.,permitting,notifications,utility clearance);site assessment tasks;methodology and procedures;
<br /> laboratory analysis;quality assurance/quality control; reporting;and project schedule.
<br /> • Health and Safety Plan. Prior to commencement of an assessment, a site-specific health and safety plan
<br /> (HSP)will be prepared. For complicated sites or site with high levels of contamination,an additional review
<br /> may be performed by Rincon's Health and Safety Officer pending site conditions.A site safety meeting will
<br /> be held whereby all field personnel will be informed of possible site conditions and provided with a copy of
<br /> the HSP.During the field work,daily tailgate meetings will be held prior to the commencement of each day's
<br /> activities and a copy of the HSP will be on-site at all times.All site personnel, subcontractors, and visitors
<br /> who enter the exclusion zone will be required to sign the HSP form daily.
