How many levels of environmental site assessment are there?
There are three key types of Environmental Site Assessments: Phase I ESA. Phase II ESA. Contamination Assessment.
What is the difference between a Phase I and Phase II environmental site assessment?
A Phase I primarily assesses the likelihood that a site is contaminated through visual observations, historical use reviews and regulatory records, while a Phase II assesses whether contamination is in fact present.
How much does a Phase I environmental site assessment cost?
Phase I environmental site assessment costs usually start at around $1400 but can go up to $4600 or above, depending on the size and complexity of the site assessment. Some firms are open to discounting the price if you need multiple reports, thus lowering the total cost of the Phase 1 ESA process.
How long is a Phase I good for?
How Long is a Phase I ESA Valid? You may be wondering on the specifics of how long a Phase I ESA is good for in the eyes of the law for a property. The simple answer is one year – if the Phase I ESA was completed more than 365 days ago then it must be re-completed as it is no longer valid.
Why do I need a Phase 1?
The purpose of the Phase 1 ESA is to perform adequate due diligence as part of the property transfer in order to limit the liability of property buyers from previously existing environmental conditions. If they are discovered after you have purchased the property, you may have a liability.
How long are Phase I ESA good for?
one year

Which phase of environmental site assessment involves the actual remediation of a site?
Phase III Environmental Site Assessments Phase III ESA’s, also known as Remediation Investigations/Feasibility Studies, are a necessary step in the environmental remediation process of environmental contaminants from a property.
Which phase of an environmental assessment confirms contamination at a site?
A Phase II Environmental Site Assessments is a test performed to confirm or deny environmental contamination and quantify environmental risk, also known as a recognized environmental condition that was identified in a Phase I Environmental Site Assessment.
How do you conduct a Phase 1 environmental site assessment?
A Phase 1 ESA interviews with past and present building occupants, and with owners of neighboring properties are also conducted to validate past uses. A Phase 1 ESA does not involve any testing of things like paint, soil, or moisture, though a visual inspection may indicate the presence of hazardous materials.
Who is developing TH-302 in the US?
In the US, Threshold will have primary responsibility for development of TH-302 in the soft tissue sarcoma indication. Threshold and Merck KGaA will jointly develop TH-302 in all other cancer indications being pursued.
What is threshold’s TH-302?
Merck Serono, a division of Merck KGaA, Darmstadt, Germany, recently announced that a global agreement was signed with Threshold Pharmaceuticals, Inc., South San Francisco, to co-develop and commercialize TH-302, Threshold’s small molecule hypoxia-targeted drug.
What is the mechanism of thath-302 activation?
TH-302 is a hypoxia-targeted drug that is thought to be activated under tumor hypoxic conditions, a hallmark for many cancer indications. Areas of low oxygen levels (hypoxia) within tissues are common in many solid tumors due to insufficient blood vessel growth.
