Phase I ESAs:

STERLING performs environmental site assessments (ESAs) using American Society for Testing and Materials (ASTM) Standard E1527-2005 for All Appropriate Inquiry (AAI), the industry standard for performance of environmental due diligence typically required by lenders and regulatory agencies.  Phase I ESAs are typically conducted to evaluate the potential for release of hazardous substances or petroleum products, and to identify “recognized environmental conditions.”

A Phase I ESA under this method consists of:

  • Reviewing governmental records (tax maps, building permits, zoning approvals) and databases (environmental permits, spill reports, remedial actions)  
  • Reviewing available literature (prior reports, permit records), aerial photographs and available mapping (e.g., topographic and fire insurance maps)
  • Interviews with government officials and other parties knowledgeable of the property and its history (current and past owners/occupants)
  • Conducting site inspection (including building interior, exterior, and observations of adjacent properties)
  • Report preparation

STERLING performs Phase I ESAs for a wide variety of clients, such as parties conducting pre-acquisition due diligence on multiple properties, individuals and small companies interested in buying a property, attorneys assisting clients, small and large companies wanting to assess their own property before initiating the sales process, and developers needing to control risk prior to a major investment.  STERLING is experienced in transitioning from the Phase I ESA process to subsequent steps while assisting clients in their specific needs. 

Phase II ESAs:

Phase II ESAs generally consist of a more extensive investigation into identified environmental conditions.  The objective of a Phase II ESA is to evaluate the environmental condition in order to provide sufficient information regarding the nature and extent of contamination to allow informed business decisions.

A Phase II ESA may include:

  • Environmental sampling (soil, groundwater, surface water, soil vapor)
  • Geophysical surveys (radar, magnetometer)
  • Test pits and/or trenches
  • Dye tracing

STERLING has designed and completed Phase II investigations on many properties with a wide range of histories including locations of former or active:

  • Spills of petroleum, hazardous chemicals or pesticides;
  • Petroleum or chemical tanks;
  • Fuel stations;
  • Factories;
  • Dry cleaners;
  • Container storage areas;
  • Floor drains;
  • Landfills;
  • Pesticide storage or application;
  • Solid waste storage; and
  • Waste collection floor sumps.

STERLING has been involved in negotiations between buyers and sellers regarding cleanups where environmental conditions have been identified.

Phase III ESAs:

Phase III efforts involve remediation or mitigation of sites impacted by petroleum or hazardous substances.  STERLING has utilized its expertise to design and gain NYSDEC approval for remedial or mitigating work plans, to obtain competent contractors, to supervise the work effort and conduct and report upon the confirmatory sampling.

Geographic Information Systems (GIS) is a powerful tool for environmental analysis, interpretation and visualization, and is an essential component of STERLING’s business.  From preliminary mapping to analyses, GIS supports a wide range of projects related to solid waste landfills, infrastructure, wetland science, etc.  STERLING staff utilize the latest software technology, ESRI (ArcGIS), AutoCAD and Trimble GPS to provide clients with ways to maximize their use of and manage their assets more efficiently.

Our commitment to Renewable Energy...

Sterling’s commitment to Renewable Energy is evidenced by the 1,100 square foot rooftop photo-voltaic (PV solar) electric system installed in 2011.  The system consists of three Sunny Boy 5000 US inverters employing 84 Schüco MPE 180 MS 05 modular panels. The system has an installed capacity of 15.12 kWs connected to the electric grid.  The system provides for the following:

  • The average monthly PV solar electric generation is 1,390 kWhrs.
  • The building averages 3,316 kWhrs of monthly electric usage.  The PV solar panels provide 42% of the average monthly electric power needs.
  • In its first full year of service, the PV solar electric system generated 16,776 kWhrs of electricity, which for the NYISO Grid mix results in the avoidance of approximately 12,000 tons of CO2 based carbon emissions.
  • To date, the PV solar system is running at approximately a 13% capacity factor. Photovoltaic power capacity is measured as max power output under standardized test conditions. The actual power output for any given PV solar system is typically below 25% and is dependent on geographic location, weather conditions and other conditions.

STERLING recognizes that waste materials often have potential as marketable commodities and can be utilized beneficially. 

STERLING often develops solid waste management solutions that create significant value for clients by utilizing solid waste as a construction material or as a substitute for a raw material.  STERLING has successfully identified beneficial construction applications for certain waste materials resulting in material becoming an asset rather than a liability requiring disposal at a permitted facility.  STERLING has also developed landfill construction, operational and closure programs that utilize solid waste as cover materials, thus avoiding the need to purchase earth materials at prevailing market prices. 

STERLING routinely utilizes the following materials in landfill closure or general construction projects:

  • Construction Surplus Soil
  • Stone
  • Wood Chips
  • Plaster
  • Brick
  • Pavement
  • Coal Ash
  • Class 1 Compost
  • Crushed Glass
  • C&D
  • CKD
  • Masonry Products
  • Rock Dust
  • Concrete
  • Clinker
  • Clearing & Grubbing Materials
  • Wood
  • Roofing Materials
  • Dewatered Sewage Sludge/Soil Mixture
  • Foundry Sand
  • Many entities are taking advantage of incentives to redevelop lands contaminated by past operations in order to bring new uses and value to the site.

    Such efforts involve determining the extent of contamination and current environmental risk; analyzing alternatives for future uses, determining the feasibility of selected options and environmental monitoring of redevelopment construction.
