(24 cards)
What is a Phase One Environmental Site Assessment?
A preliminary environmental report that includes site walk-through and records review, but no testing.
Who conducts Phase One assessments?
Environmental professionals with expertise in site conditions and records research.
What is the purpose of a Phase One assessment?
To determine if further environmental testing (Phase Two) is necessary.
What happens if a Phase One identifies concerns?
A Phase Two is recommended to perform testing for contaminants like lead, asbestos, or petroleum.
What is a Phase Two Environmental Site Assessment?
A detailed investigation involving sampling and testing of potentially hazardous materials.
What are Recognized Environmental Conditions (RECs)?
Indicators of environmental contamination, such as visible asbestos, oil tanks, or industrial waste.
What is the architect’s role in environmental issues?
To interpret environmental reports and incorporate recommendations into the contract documents.
Why don’t architects make environmental remediation recommendations?
Because they lack legal liability coverage and expertise compared to environmental engineers.
What is encapsulation in environmental remediation?
Covering hazardous materials to prevent exposure, such as concrete slabs over contaminated soil.
What is removal in environmental remediation?
Physically removing and disposing of contaminated materials.
What is remediation in place (in situ)?
Treating contamination on site using chemical or biological methods.
What is bioremediation?
Using living organisms like plants or bacteria to neutralize or absorb pollutants.
What does a Phase One Executive Summary contain?
The conclusion on whether RECs exist and if Phase Two is needed.
How can past land uses affect site contamination?
Contaminants can migrate through soils from neighboring sites, even after decades.
What kind of historical data is reviewed in a Phase One?
Sanborn maps, aerial photos, topographic maps, and government databases.
What would you do if a Phase One reveals no RECs?
Proceed with development unless minor monitoring or mitigation is suggested.
Why is sanding old lead paint not recommended?
It creates airborne lead dust, increasing health risks.
When is lead paint removal preferred over encapsulation?
When renovating spaces for vulnerable users like young children in schools.
When might encapsulation of lead paint be acceptable?
In settings like nursing homes where risks and exposure levels are lower.
Why must encapsulated lead paint be durable?
Because wear and tear (e.g., children chewing or bumping) can expose hazards.
What are environmental engineers responsible for?
Providing recommendations in Phase One and Phase Two reports.
What are architects responsible for?
Helping clients understand environmental reports and integrating guidance into CDs.
How should architects respond to mercury-contaminated soils?
Refer to environmental engineer recommendations; common methods include solidification, stabilization, or soil washing.
Why are sump pumps and floor drains noted in Phase One?
They can indicate potential underground water or contaminant management systems.
