What is a Phase 1 Site Assessment
A phase 1 site assessment essentially produces the same report as the preliminary site assessment with one exception – – it includes the results from testing performed during the on – site inspection of both the interior and exterior of the site. The results of this testing are usually included as a separate section of the report. The phase I is the assessment most used by potential purchasers and also by lenders when the lender specifies the type of assessment to be done.
When performing the site inspection for phase 1 report, the consultant will carry the sampling kit as he or she performs the ground inspection. The kit will contain various types of containers and sampling instruments as well as labels and a notebook for recording samples taken. The process is relatively simple and should not take much more than the inspection for a PSA.
Exterior testing for phase 1 studies is generally limited to areas of specific interest. An environmental consultant will look for certain “signs” that indicate the necessary to do soil testing, i.e. Visible soil staining, areas without any vegetation, railroad track easements with staining on and around the tracks, cleared areas around electrical transformers.
Polychlorinated biphenyls are of particular concern: they were widely used in hydraulic fluids and oils on trains and as insulating liquids and transformers. also of interest are petroleum hydrocarbons which result from various oils, gasoline’s, hydraulic and other fluids that have been spilled or dumped on the ground, and the various.
Underground storage tanks are a major cause for concern on any property. Evidence of an underground storage tank in the form of gas pumps, filling facilities, including our bowels will almost certainly be noted and tested. Testing should be done to determine whether an underground storage tank has become a leaking underground storage tank.
Three types of tests are performed on underground storage tanks to evaluate the soil, the tank, and the groundwater. Taking soil samples 3 to 5 feet down is standard procedure. The samples are tested for petroleum products and their derivatives to determine if there has been any spillage or leakage. In conjunction with the soil sample, a “tightness” test is usually performed on tanks using an instrument positioned inside the tank. This is used to determine the presence of a leaking underground storage tank.
A monitoring well test underground water underneath the tank is always recommended in these situations. Although such test can be very expensive and time-consuming, most experts agree that any tank more than five years old has a 95% chance of leakage. From the property purchaser’s perspective, a test of underground water should always be performed.
When “active” tanks have annual tightness test records that go back 5 to 7 years and reveal no leakage, soil tests are unnecessary. These records should be easy to obtain through the owner of the tank – – the property owner or tenant – – tank owners are required by law to make such tests and keep records of them. The tank owning tenant should be required to provide the management company with a copy of each of these tests when completed. The manager taking over management of the property that has underground tanks and has no test results on file should request tests immediately upon commencement of the management contract.
The results of phase 1 tests should be included in the detailed section of the report along with copies of laboratory analysis and testing diagrams and parameters to support documentation sometimes provided as appendixes to the report because of the number of tests involved. The executive summary should contain a synopsis of the test results.
