Services may include, but are not limited to the following: A. Preparation of site-specific work plans (including technical proposals and cost estimates) for specific technical tasks. B. Review of site files, site reconnaissance, property ownership determination, right-of-entry acquisition, and receptor surveys. C. Various hydrogeologic and contaminant assessment activities, including monitoring/remedial well installation, groundwater sampling, surface water and sediment sampling, soil gas sampling, crawl space sampling, indoor air sampling, soil sampling, aquifer testing, human exposure assessments (evaluation of site-specific risks to potential receptor populations from site-related contamination), and other tasks related to comprehensive assessment of groundwater, surface water, sediment, soil, soil gas, and indoor air at designated sites. D. Various geophysical assessment activities to delineate the vertical and horizontal extent of waste, subsurface piping and tanks, and possible geologic structures. E. Various land surveying activities. F. Prepare and record notices of residual petroleum and public notification. H. Preparation of site-specific mitigation plans, providing an evaluation of various mitigation alternatives for groundwater, surface water (including wetlands), sediment, and/or soil gas (including structural vapor intrusion) at contaminated sites. I. Design and installation of water supply alternatives (new wells, point-of-entry water treatment systems, bottled water, and extension of public water lines). J. Coordination and oversight of demolition of structures including the disposal of demolition debris. K. Management and oversight of specialty and engineering subcontractors, vendors, or contractor personnel. L. Preparation and submittal of all required permit applications for the construction and operation of various mitigation systems at designated sites, including National Discharge Pollutant Elimination System (NPDES), non-discharge, and air quality permit applications as may be required by the Department or other governmental agency; development and implementation of procedures designed to expedite acquisition of such permits so that site cleanups may proceed as quickly and effectively as possible. M. Implementation of site-specific mitigation plans, including management/oversight of all phases of site remediation. N. Preparation and implementation of site-specific health and safety plans, under the supervision of a qualified health and safety officer, so as to ensure compliance with all applicable Occupational Safety and Health Administration (OSHA) regulations for worker safety and for the health and safety of nearby residential and business communities during all phases of site assessment and remediation. O. Preparation and submittal of all required reports and any miscellaneous documentation as requested by the Department or Contract Administrator according to schedule(s) agreed to by both parties; submittal of site-specific project status summaries (technical progress, identification of problems/delays, and cost updates) to the Department at the time of invoice submittal. P. Technical and administrative support as needed at public hearings or public meetings to discuss elements of proposed investigation and/or mitigation plans. Also, as needed technical and administrative support in providing expert testimony at hearings, meetings, depositions, and in litigation involving the Department related to the Underground Storage Tank Section State-Lead Program expenditures at UST sites. Q. Implement tank closures/removals in accordance with all applicable state and federal rules and regulations, industry standards and codes of practice, and the most recent version of the UST Section's Guidelines for Site Checks, Tank Closure, and Initial Response and the Reasonable Rate Document Scope of Work documents in effect at the time of the work. R. Prepare and submit all required notices and reports in accordance with the most recent version of the UST Section's Guidelines for Site Checks, Tank Closure, and Initial Response, the UST Section's Guidelines for Assessment and Corrective Action, and the UST Section's Reasonable Rate Document Scope of Work, documents in effect at the time, according to schedule(s) agreed to by both parties. S. Contract administration, budget tracking, and invoicing. T. Coordinate and oversight of soil removal activities including offsite disposal of contaminated soils.
