Section 6.0, and its associated subsections, is limited to those designs for an AVMS that EGLE has contracted and is funded by public money or dollars. An owner/operator is not required to and should not include this section for a submittal to EGLE for official review. The information in this section is based on the State Occupation Code, Act 299, Article 20 Section 339.2011 which requires any public works in excess of $15,000 to be prepared, reviewed, and overseen by a licensed professional engineer (PE). Though 339.2012 exempts single family home construction less than 3,500 sq ft, for AVMS systems where the estimated cost of the installed AVMS (based on design, installation, and commissioning) is expected to be greater than $15,000, the additional information in this section must be provided.
6.1 AVMS design professional engineer and license number
6.2 Engineers estimated cost of the AVMS considering design, installation, and commissioning
In order for EGLE to complete its review the following information must be included in the identified subsections (even if it otherwise appears):
6.3. Design flow (total and at each suction pit/extraction point)
6.4. Design vacuum (at the fan and at each suction/extraction point)
6.5. Selected blower/fan with pump curves
6.6. System total dynamic head
6.7. Pipe sizing
6.8. Pipe layout schematic w/ any valving
6.9. Suction pit/extraction point(s) design/layout
6.10. Location and selection of all flow and pressure gauges
6.11. Sampling locations
6.12. Failsafe devices
6.13. Permitting evaluation and information
6.14. Sealant information
6.15. HVAC and back drafting evaluation
Information provided in Section 6.3 through 6.12 should be based on the Pre-Design SubSlab Testing that was completed in Section 2. Typically, EGLE will not contract for a presumptive mitigation system without a building and known or potential unacceptable exposures; however, if pre-design sub-slab testing cannot be completed due to a structure not being present, the submitter should contact EGLE on how to provide sufficient information to complete the requirements of this section. Each section identified above must provide the necessary supporting documentation, calculations, and figures as required to support the conclusions being drawn.
Attachment 1 - Building survey
Note: This building survey is intended to be used only as an example in developing a building survey that is specific to the site with the appropriate information for the structure in which a vapor mitigation system has been proposed or installed. This form may not contain all of the information necessary to design a vapor mitigation system for a particular structure. The development and use of this form is fundamentally important to document site conditions during future inspections to confirm if any modifications to the structure have been made, and whether a more detailed assessment is warranted. It should be updated on an annual basis.
