What are the commons environmental hazards?
Asbestos containing material
Lead Based Paint
Radon
Underground Storage Tanks (UST)
Polychlorinated Biphenyls (PCBs)
What is Asbestos containing material?
Asbestos containing material is a naturally occurring fibrous mineral utilized for its thermal insulating chemical and thermal stability and high tensile strength. The three most common types of asbestos are chrysotile, amosite, and crocidolite.
What are some common misconceptions about asbestos?
- Asbestos is not a banned substance in the United States
- Only certain applications and new uses of this mineral has been banned
- It is still a common ingredient in floor tile and roofing tars. It is generally not listed as “asbestos” on the ingredient list and is more commonly labeled “Canadian mineral fibers”.
- There is no date referenced in the NESHAP documents.
- Compliance with 40CFR61 Subpart M is required prior to any demolition renovation activities. (This is NESHAP).
What is the difference between friable and non-friable asbestos?
The term “friable” is used to describe asbestos that can be reduced to dust by hand pressure (e.g. pipe insulation). If there is asbestos and it is friable or damaged it is recommended by the EP that it be removed.
The term “Non-friable” refers to asbestos that is too hard to reduce to dust by hand pressure (e.g. transite siding, vinyl, floor tile).
When is a Lead Based Paint Screening and Risk Assessments required?
Lead based paint (LBP) was banned in 1978. If a multifamily structure was built pre-1978, then a lead based paint and/or risk assessment is required. Lead based paint is only required for multi-family structures as lead based paint is not regulated in facilities occupied by senior citizens and/or disabled individuals.
What is a radon gas screening?
Radon gas screening requires short-term radon testing devices, typically activated charcoal canisters/kits (most common), electretion devices, or continuous radon monitors. Tenants are requested to maintain a closed building condition for 12 hours prior to and during the testing. Testing devices are placed for 48-96 hours and then sent to a laboratory for analysis. Testing is required on 100% of ground floor units in all radon zones.
What is the regulation that environmental professionals must adhere to when testing for Vapor Encroachment?
ASTME 2600-22 is the Standard Guide for Vapor Encroachment Screening on Property involved in real estate transactions. The purpose of this report is to determine if there is a potential for subsurface vapors from volatile organic compounds (VOCs), semi-volatile organic compounds (SVOCs) and inorganic volatile compounds to occur below existing and/or proposed structures.
What is an Underground Storage Tanks (UST)?
An underground storage tank is a tank and any attached underground piping that has at least 10% of its combined volume underground which can be located at interior or exterior locations and under pavement or grass. They are typically used to hold petroleum products, raw chemical materials or waste products.
What is Polychlorinated Biphenyls (PCBs)?
PCBs are a mixture of synthetic organic chemicals with the same basic chemical structure and similar physical properties ranging from oily liquids to waxy solids. Due to the non-flammability, chemical stability, high boiling point and electrical insulating properties, PCBs were used in hundreds of industrial and commercial applications. They are found in electric transformers, hydraulic equipment and fluorescent light bulbs. PCBs can be a cause of soil contamination.
What does the Phase I environmental report contain?
- Site reconnaissance of the subject property and a visual survey of the adjacent properties to evaluate potential RECs.
- Interviews with past and present owners, operators and occupants.
- Record Review of historical sources of information and federal, state, tribal, and local government records.
- The written report must include the findings, opinions and conclusions of the EP and supporting documentation. The findings section should also include identification or absence of RECs, historic RECs, CRECs and de minimis conditions.
What does the Phase II environmental report contain?
The phase II site assessment involves invasive sampling of the soil and ground water for testing of actual contamination found in the Phase 1 assessment, a determination of the amount of contamination, as well as air quality tests. Phase II is required if the Phase I indicates there is a REC and corrective action is potentially feasible, the Phase I comes to no definite conclusion regarding the presence of a REC.
What is the regulation that environmental professionals must adhere to when completing a phase II enviromental report?
ASTME 1903-19
What are the non-scope considerations?
- Floodplain Managment
- Wetlands
- Endangered Species
- Historic Preservation
- Noise
- Above Ground Storage Tanks (AST)
- Coastal Barriers Resources
- Coastal zone management
- Environmental Justice
- Pipelines
- Fall zone hazards
- Operating and/or abandoned oil and gas wells, sour gas wells, and slush pits

- Airport hazards and clear zones
- Chemical and radioactive materials
- Sole source aquifiers
What is Floodplain Managment?
A FEMA Flood Insurance Rate Map is obtained and used to determine if the property is located within a FEMA designated flood plain and/or flood way. The following documentation is used:
* FEMA Floodway Map
* Elevation Certificate
* Letter of MAP Amendment (LOMA)
* Letter of MAP Revision (LOMR)
* ALTA/ACSM Land Title Survey
