ASTM E1903-11 Soil Vapor Intrusion Risk Investigation

Caltha LLP Project Summary

Project: SBA Vapor Intrusion Risk Study
Client:
National Bank
Location(s):
Saint Paul, Minnesota


Key Elements: Site investigation, subslab soil vapor testing, vapor encroachment, Small Business Administration loan


Overview: Caltha LLP conducted a Soil Vapor Intrusion Risk Assessment for this commercial property located in St. Paul. The Phase 1 assessment conducted a Tier I Vapor Encroachment Screening Assessment using ASTM E2600-10. This assessment determined that the potential for risks of vapor intrusion could not be screening out, therefore a Phase 2 vapor intrusion risk study was recommended.


An investigation approach was prepared which met the requirements of ASTM E1903-11 (Standard Practice for Environmental Site Assessments: Phase II Environmental Site Assessment Process). Subslab soil gas samples were collected from inside the building. Results were compared to MPCA vapor intrusion screening values. Although some volatile organics were detected in subslab soil gas, all concentrations were below agency risk-based screening values.

Soil and Groundwater Investigation In South Dakota

Caltha LLP Project Summary

Project: Tank Farm Investigation
Client:
Agricultural Production Sector
Location(s):
South Dakota


Key Elements: Phase 2 Investigation, leaking tank, SPCC requirements


Overview: Caltha LLP was retained by a potential investor group to conduct a Phase 2 Limited Site Investigation (LSI) at this large farm site. During a Phase 1 Environmental Site Investigation, visual evidence of past leaks and spills were identified within the tank farm. Due to recent changes to Federal Spill Prevention, Control & Countermeasure (SPCC) rules which would require above ground tanks at agricultural facilities to comply with SPCC rule, the tank farm was expected to require upgrades. The key question was what cost impact would be expected during tank farm upgrade to address existing contamination. The results of the investigation provided clarity to the potential investors on the range of cost impacts.

Changes To Vapor Intrusion Screening In Michigan

MDEQ has proposed to use a new tiered process for vapor intrusion, as recommended by the CSA. The Soil and Groundwater Volatilization to Indoor Air Criteria (SVIIC or GVIIC) in the 2013 rules are replaced by the Volatilization to Indoor Air Screening Levels and Criteria in the proposed rules. The proposed Volatilization to Indoor Air Screening Levels and Criteria protect for chronic exposures, in general, but also protect for acute toxicity for those volatile hazardous substances that have short-term health effects .


The tiered approach will reduce the number of site-specific evaluations that require a Department review by providing “off-ramps” at each tier:


VI Tier 1:
  • Initial generic screening levels.
  • Exceedances do not result in facility status, and DEQ will not use this Tier to require remedial action.
  • If exceeded, further assessment through the tiered process is needed.
VI Tier 2:
  • Incorporates facility-specific geologic and hydrogeological conditions
  • Compliance with VI Tier 2 criteria results in unrestricted residential closure.
  • Exceedances result in facility status.
VI Tier 3A:
  • Incorporates land use and building-specific information for generic criteria.
  • Identifies the need for response activity or a site-specific evaluation completed in VI Tier 3B.
VI Tier 3B:
  • Site-specific alternative approach.
  • Requires Department approval to implement.
