Remote Telemetry for Active Exposure Pathway Mitigation Measures (AEPMM)

AEPMM Telemetry Device Registration Information

This information is applicable to certain response actions taken to address exposure to oil or hazardous material under the Massachusetts waste site cleanup regulations.

Active Exposure Pathway Mitigation Measures (AEPMM) installed to prevent the migration of subsurface vapors into a building that are part of a Permanent Solution, Temporary Solution or Remedy Operation Status require the use of remote monitoring technology to provide immediate notification to both MassDEP and the owner and operator of the building protected by the AEPMM when:

  • the vacuum level is outside the acceptable range and
  • when such level returns within the acceptable range.

This requirement is specified in the Massachusetts Contingency Plan at 310 CMR 40.1025(3)(d) and 40.1026(3)(d).

The steps below outline the AEPMM telemetry registration process (310 CMR 40.1027).  Any questions regarding remote telemetry for AEPMMs can be sent to brian.roden@Mass.Gov.

1. Select and install AEPMM Remote Monitoring System

System must be able to communicate via email. 

System must be able to immediately communicate BOTH when the vacuum level is outside the acceptable range (shutdown) and when such level returns within the acceptable range (restart).  
Shutdown and Restart event notifications must be sent by email to: AEPMM.BWSC@mass.gov

Typically, each fan or blower needs to be registered as a separate device.

System must be able to communicate in the CSV (comma separated values) format and as close to the sequence specified below as possible, with each value enclosed in quotes.              

    Site RTN, Device Number (01, 02, etc.), Event Description (Shutdown, Restart), Event Date: YYYYMMDD, Event Time: HH:MM (24 hour format).

For example, an email message notification of a shutdown of device number 01 belonging to RTN 1-12345 that occurred at 7:25 PM on June 20, 2024 would look like:

    "1-0012345","01","shutdown","20240620","19:25" 

IF the device is not capable of reporting in this exact sequence, then, at a minimum, it must relay ALL of the required information requested above. It is crucial that the data, regardless of order in which it is presented, be enclosed in quotation marks and be transmitted in a single text block message (not transmitted in separate emails). If the date format cannot be presented as YYYYMMDD, then the format in which the date is delivered must be the same EVERY TIME a message is sent. If the 24 hour time format cannot be met, then at a minimum the device must differentiate between day and night (AM and PM).

Notification emails should include the word "Notification" in the email subject.  

2. Register the System with MassDEP

Initiate the AEPMM remote monitoring system registration by completing the Initial Device Registration using the Telemetry Device Registration Form.

3. Conduct a System Test

After you have submitted the Telemetry Device Registration Form, MassDEP will contact the person listed as the Contact in the form by email within 5 business days to arrange to conduct a manual system shutdown and restart test in order to confirm that the communication between the AEPMM telemetry and MassDEP happens as required.

4. Receive Confirmation

Within five business days of the test, you will receive an email from MassDEP of the results of the communication test.

If the test is successful, you will concurrently receive written confirmation that the AEPMM remote monitoring system has been successfully registered and the process is complete (as specified at 310 CMR 40.1027(2)(d)).
