In addition to following current ASTM Standard Designation E1527 - 13 "Standard Practice for Environmental Site Assessments: Phase I Environmental Site Assessment Process", Jade's inspectors are trained to conduct thorough visual inspections for evidence of existing or the past presence of chemical and/or petroleum storage facilities. All Phase I ESAs are conducted under the auspices of a Licensed Engineer with 25+ years of experience conducting Phase I ESAs. At minimum our Phase I report scope of work includes :
One of the most important aspects o the Assessment, Jades inspectors and trained to conduct thorough Inspections of all areas of the Asset including detailed inspections of the areas within 10' of all on site structures for evidence of petroleum bulk storage. Exterior inspections include searches for depressions where backfill has settled after a tank excavation was backfilled or asphalt or concrete patches where surfaces were repaired after a tank pull. Interior basement walls are thoroughly inspected for possible penetrations from tanks buried outside the building.
All on-site petroleum and hazardous materials identified are photo-documented and added to the site map required for each assessment. Finally, the site visit includes an inspection of all surrounding properties which a detailed inspection o those properties topographically up gradient and possible sources of groundwater contamination and soil vapor intrusion that could negatively air quality inside on-site structures.
To add to the historical information obtained from the site contact, tenants that have been on-site for several years and/or even neighbors that have lived in the area for a long time, Jade will review the following sources of information to ascertain past uses of the Property back to at least 1940.
Building and Planning Files - although not required by ASTM, Jade inspectors are required to access all building files via FOIA if necessary due to the wealth of historical information provided in these files.
Title Information - Again although not required by ASTM, Jades inspectors are required to conduct title searches on all Property's back to 1940 or the extent feasible due to the wealth of info that can found in these records.
Fire Marshal Files - Many Fire Marshals offices collect data regarding the types and quantities of chemicals and petroleum's a facility maintains so that such information can be reviewed and understood in the event of a fire.
Historical Aerial Photographs
Sanborn Fire Insurance Maps
Geology and Hydrogeology
The following site characteristics will be collected from readily available sources such as at the county Soil Conservation Service Office in order to provide a better understanding of how readily contaminants could migrate onto or off site should they reach the aquifer.
Fire Marshal Office Records - for records of chemical and/or petroleum storage and use.
State Environmental Agencies - including databases of sites within distances of the site as specified by ASTM of site and facilities listed due to their use and storage of regulated materials including petroleum and chemicals as well as uncontrolled releases of these materials including sites currently under remediation as a result of a past spill say from a leaking buried tank.
Federal Environmental Agencies - Similarly to the state databases but on the federal level include various databases of sites that use and/or store larger quantities of select petroleums and chemicals
Interviews and Document Review
Jade considers interviews and review of older reports provided by property ownership one of the most important aspects of the Phase I process. As such, each and every inspection includes a Pre-Survey Questionnaire which is sent to the Site Contact/Owner for completion prior to our visiting the site, so that an understanding of current and past uses of the property with respect to chemical and petroleum use is known before visiting the Site. Interviews are targeted towards :
Property Tenants and Owners - Targeted to complete our Pre survey Questionnaire
Local Regulators/Town Offices
Review Provided Reports
