  • Half Moon Bay

    Site Remediation

    Half Moon Bay — Croton-On-Hudson, NY

    The Half Moon Bay development is situated on the Hudson River in upstate New York and includes 117 high-end condominium units. The active Croton Harmon Rail Yard, operated by Metro North Commuter Railroad Company, borders the Half Moon Bay site to the east. The Westchester County Croton Point Park and the former County landfill (which is now closed) border the site to the south. The Hudson River forms the western boundary.

    Over the years, spills and contamination including floating product had moved with groundwater from the rail yard, under the project site, and out to the river. A sheen could be seen at times along the shoreline. In cooperation with Metro North Rail and the NYSDEC, it was agreed to place an underground cutoff wall between the two properties and remove the affected soils from Half Moon Bay property.

    Galli Engineering, P.C. completed the site remediation at the property. Remediation activities consisted of :

    • Conducting air monitoring to ensure workplace health and safety and to screen contaminated soil for disposal and sampling locations.
    • Collection and analysis of soil samples.
    • Excavating and disposing of petroleum contaminated soil and disposing of contaminated fluid from the excavations. The affected area measured approximately 140 ft by 100 ft by 12 ft deep.
    • Installation of a subsurface barrier wall along the eastern boundary of the Remediation Area to prevent the possible migration of contaminants from the Metro North Railroad Yard onto the subject site.
    • Removal of floating product via vactor truck and oil skimmer.
    • Removal of contaminated, stockpiled soils to licensed, off-site facilities via an authorized trucking company.
    • Backfilling of open pits with clean material.
    • Bio Treatment:
      Three injection wells were installed using a drill rig equipped with a hollow stem auger. Groundwater samples from these injection wells were shipped to a lab and analyzed in a treatability study to determine a suitable approach to bio-remediate the site?s free floating product and petroleum contaminated soils. Live, specifically selected, naturally occurring microorganisms, along with a supply of balanced nutrients were periodically administered via gravity force to all three injection wells at recommended dosages and frequencies. Galli implemented a routine plan to re-treat the injection wells every 4 to 5 weeks for a total of four treatments. The bioremediation program was successful in eliminating the sheen and affected soils.The remedial activities were conducted in accordance with “Remedial Action Plan for Petroleum Contamination in Soil and Groundwater” also prepared by Galli Engineering. 2,000 tons of contaminated soil were excavated, transported, and properly disposed off-site. Over 20,000 gallons of contaminated fluid was removed from the excavations, transported, and disposed off-site at properly licensed facilities.

    • three buildings that are to remain on site.
    • Abatement of the balance of ACM on the other buildings on the subject property.
    • Removal of ASTs and USTs, along with any existing soil contamination resulting from these tanks.

    Site Supervision and Air Monitoring

    • Air Monitoring is required by the NYS Department of Labor during asbestos and lead based paint abatement.
    • Removal of ASTs and USTs, along with any existing soil contamination resulting from these tanks. At the completion of each underground tank excavation, endpoint samples will be collected from each of the four walls and the floor of the finished excavation. Petroleum contaminated soils will be disposed of in accordance with the NYSDEC STARS Program. Soil removed from the excavation will be placed directly into dump trucks or trailers for transport to an authorized disposal facility if suitable arrangements can be made. Otherwise, contaminated soil will be stockpiled, sampled for waste characterization purposes, and transported at a later date. Any excavated soil to be held on site will be stored on top of, and be covered by, layers of plastic sheet. Contaminated soil will be sampled for waste characterization purposes using analyses likely to be required by anticipated disposal facilities.

    Final Closure Activities

    • A final closure report will be prepared and submitted to the NYSDEC, seeking a no further action letter. The goal of the report will be to demonstrate that the materials excavated from the site were disposed of properly and that the site is satisfactorily restored. The report would likely include the following: A brief narrative description of project activities to date; site description and site map; summary of available previous soil and groundwater results; nature and extent of contamination; evaluation of results; conclusions and recommendations; and documentation (may include tables, photographs, PID readings, laboratory results, and C&D tracking documents, as appropriate). The actual content of the report and its acceptability to DEC will depend on conditions encountered in the field.

  • Wellington Square

    Brownfield Redevelopment and Civil Site Engineering

    Wellington Square — Bronxville, NY

    Galli Engineering successfully entered this project into the New York State Brownfield Cleanup Program. This 1.74 acre site is currently used for at-grade parking by the Village of Bronxville. The project site is located directly adjacent to the Metro North Railroad right of way at the Bronxville Station. Around 1905, the “Hotel Gramatan Power and Light Plant” was built on the middle lot of the site. Coal was used to fuel the power plant until 1961, when the plant switched over to fuel oil. In 1910, the South Bronxville (Gramatan) Garage was built on the southern lot. The garage was used as an automobile service station and a gasoline filling station. The Village of Bronxville acquired the property in the 1980s, and the Gramatan Garage and power plant were demolished and used as parking lots. There was a large amount of residual contamination and debris left on site from the demolition of the power plant, and this has negatively impacted the environmental quality of the site.

    Soil samples have demonstrated the presence of elevated petroleum constituents and total petroleum hydrocarbons. Portions of the site have been assigned spill numbers by the New York State Department of Environmental Conservation (NYSDEC). Based on the age of some of the buildings located on the project site, there is reason to suspect the presence of lead containing paint and asbestos containing materials.

    To address these issues, Galli Engineering prepared the site-specific Health and Safety Plan and all required workplans and protocols for the investigation of the areas of environmental concern, and mitigation of these areas. Galli completed the Phase I and Phase II Environmental Site Assessments. This work included the use of ground penetrating radar to survey the entire parking lot area, installation of soil borings, groundwater and soil sample collection and a geotechnical investigation. Analytical data confirms that the subject property has been impacted by contaminants that are consistent with the past use of the parcels (i.e. a former gasoline service station, automotive repair and parking facility at the south parking lot; and a former heat and light power plant at the central parking lot property). Based on the field results, Galli made recommendations for environmental site remediation and mitigation of existing site contamination.

    The development of the property will include up to 65 luxury, empty nester condominiums in four-story buildings and the construction of a below grade 300 space parking garage. Galli Engineering designed a sub-slab venting system, Stormwater Pollution Prevention Plan and Stormwater filtration and detention basin design amongst other civil engineering aspects of the building.
