Geraghty & Miller, Inc produce a summary report of exis ing information concerning the groundwater conditions and the Croton Point Sanitary Landfill for the County The County receives a Preliminary Engineering Report the planned expansions of the Croton Point Landfill Rotfield Associates & Wehran Engineering. of EXHIBIT B: PROJECT CHRONOLOGY continued Ecological Analysts, Inc submits their Croton Point Terrestrial Assessment Study which details the impacts of the Landfill. The County files Environmental Impacts Statements for the expansion and management of the Croton Point Landtill. The County releases a report concerning Engineeripg, Final Management Plans and Environmental Assessments o f t h e Croton Point Landfill, prepared by Dolph Rotfield Associates & Wehran Engineering. The County Departments of Public Works and Health complete a comprehensive document titled "The 1981 Croton Point Landfill Investigation" which discusses the health impacts of the site. t The USEPA directs NUS Corporation to perform a "S te Inspection Report and Hazard Ranking Model" for the CPSL. N SDEC utilizes this report to classify the landfill as an inactive hazardous waste site. The County enters into a Stipulation and Order witfh the Federal Government concerning the CPSL. The County begin$ negotiations with NYSDEC concerning a Consent Order and Title 3 funding of the Landfill Remediation Program. The County contract/s with VelzyWeston to prepare work plans to investigate and st$udy the Site. Velzy-Weston submits a report entitled "CPSL:Back round & Synopsis of Key Technical Reports" t o the County and NYSDE 3. NYSDEC and Westchester County reach agreement on 4he documents that govern the current remedial program: the NY8 Consent Order requiring a complete remedial program and the worR plans for the RIIFS. The County submits an application for State Assistance under Title 3 of the 1986 EQBA to reimburse costs incuraed under the landfill remedial program. The State accepts the application with an estimated total cost of $23,800,000 which inclqdes RI/FS ($2,400,000), Design ($700,000) and construction (1$20,700,000) costs. The contract is executed in Jan 1990. FieLd work begins for the RI/FS. A public informational meeting concerning the remqdial program and the Title 3 State Assistance Program is held at the CrOton Village Municipal Building. The County submits a Preliminary Site Characterization report which includes discussions of the need to eventually cap the site. DEC requests the County t o review the applicability of an early remedial action in the form of a cap over the landfill. The County submits and the DEC accepts a report which shpws that a accelerated remedial alternative for the CPSL would be a cap and that this action would not hinder the feasibility of other applicable alternatives. The County solicits engineerin$ proposals for Remedial Design and selects Gibbs & Hill im July 1990 t o implement this accelerated remedial action. The County submits the "Marsh Quality and Trends Report" on the Croton Marsh. Interim draft RI reports are prepared in June 1990. A second public informational meeting is held at the Village municipal building t o present the results of the RI work to date and to present the preliminary plans for the early cap. The County submits a revised "Interim Report on the RI/FS at CPSL" in response to DEC questions on the 611990 draft report. The County submits additional information concerning the tevised Velzy-Weston interim report under the title "Data UeeabilLty Report:CPSLm. The County also submits the "Landfill Cover Design Report" prepared by GH. The County receives a "Preliminary Evaluation of Volatile Emissions at CPSL" from Velzy-Weston. The DEC authorizes $he County to proceed with partial construction of the leachate transfer system in response t o a County request concerning their obligations under the Federal Order. The DEC and the County conclude negotiations for the scope of work for the second phase of work needed t o complete the RI/PS. The work begins and is completed in the summer of 1991. The County awards a $1,300,000 contract to Sentrail Constnuction Company for construction of the leachate transfer system which is completed and operational by 4/92. This system begins to dewater the leachate mounds in the 2 lined cells and assists in .the management of leachates from the original cell. The County holds a public hearing in the Village on their Draft Environmental Impacts Statement:Proposed Dredging for Materials Delivery:CPSLm. Due t o several issues the County does not pursue the dredging option and final design activities begin. .
